​My car is making a severe rattling noise when driving on even the slightest bumps. There has been a recall issued regarding a suspension issue with loose bolts. I have tried calling Acura, have written an email and sent a registered letter to the corporate office. They do not respond. ​Recall Campaign Numbers: 25V234000, 25V018000, 26V306000, 26V112000, 24V614000 ​Acura Case Number: 16703145 ​Core Complaint Description: ​"Dealer refused immediate recall service due to staffing shortages (only one EV technician), scheduling first available appointment 5 months out.

The "shark fin" antenna on the top of the car came off while driving on the highway. I've had no prior issues with it being loose nor did I notice any issues with it being loose when I wash the car. I did not notice it came off until I returned home. The fact that normal highway speeds could cause it to dethatch puts other drivers at risk from the flying debris.

The contact owned a 2024 Acura ZDX. The contact stated that while driving on several occasions, the vehicle unintendedly applied the brake with the brake warning light illuminated and an audible alert sounding. The vehicle had experienced phantom braking. The contact stated that due to the failure, another vehicle crashed into the rear of the vehicle. The manufacturer was notified of the failure. The vehicle was taken to the dealer, but the dealer was unable to duplicate the failure. The failure mileage was 18,200.

The contact owns a 2024 Acura ZDX. The contact received notification of NHTSA Campaign Number: 26V306000 (Back Over Prevention); however, the part to complete the recall repair was not yet available. The contact stated that the manufacturer had exceeded a reasonable amount of time for the recall repair. While the contact's wife was reversing, the rearview camera displayed a distorted or blank image. The dealer was made aware of the failure but confirmed that parts were not yet available. The failure mileage was 10,000.

2024 Acura ZDX Type S displayed “Service Brake Assist,” “One-Pedal Driving Unavailable: Use Brake for Stopping,” and “Auto Hold Unavailable” simultaneously at 5995 odometer miles. An electronic ticking or clicking sound occurred from the brake-control area and the vehicle experienced a jerking sensation when coming to a stop. This noise originates from under the dashboard near the steering column and suggests a possible malfunction in the braking or electronic control systems. The warnings cleared after the vehicle was shut down and restarted several times. This VIN previously had DTC C2A22 and brake operating simulator-related warranty repairs but this issue has persisted after being inspected by Acura and confirming that all braking systems systems check out.

I am reporting a prolonged inability to obtain the rearview\-camera safety recall repair for my leased 2024 Acura ZDX, campaign R06, NHTSA number 26V\-306\. The recall is dated May 14, 2026\. On July 6, 2026, my husband brought the vehicle to Cerritos Acura for a scheduled recall repair appointment at 8:20 a\.m\. The dealership had sent an appointment reminder\. After he arrived, staff said the replacement part was unavailable and the recall could not be completed\. When he asked why the appointment had been accepted and confirmed without the required part, staff apologized but told him to check with the dealership before coming in the future\. We were not notified of the parts shortage before making the trip\. I am attaching the appointment reminder and service adviser’s message from that visit\. Despite repeated calls to dealerships and Acura Client Relations, we continue to be told that parts are unavailable and that someone will notify us\. As of October 4, 2026, the recall remains incomplete, with no estimated parts\-availability date or repair date\. The recall warns that moisture intrusion can cause a blurry, distorted, or black rearview\-camera image, increasing crash or injury risk\. Acura lists parts as available in limited supply, and CARFAX lists the remedy as available, but we have been unable to obtain the repair\. This complaint concerns the failure to provide the recall repair, not a specific camera failure or crash\. I have also submitted a written complaint

I am reporting repeated unintended automatic emergency braking in my 2024 Acura ZDX. The vehicle was leased new on April 9, 2025 and currently has approximately 9,500 miles. The system involved appears to be the Forward Collision Warning/Automatic Emergency Braking system and related braking controls. The vehicle is available for inspection upon request. On September 14, 2026, while driving at less than 25 mph, the forward collision warning suddenly activated even though there was no pedestrian, vehicle, or other apparent obstruction requiring emergency braking. Immediately after the warning, the vehicle automatically applied the brakes abruptly. The sudden braking caused the driver to be thrown forward, and she experienced neck pain afterward. This is not an isolated incident. The vehicle has experienced similar unintended collision warnings and/or automatic braking events multiple times and at different speeds, including at higher roadway and freeway speeds. These events create a serious safety risk because sudden, unexpected braking can cause the vehicle to be struck from behind, can cause injury to the occupants, and could potentially cause the driver to lose control of the vehicle. The vehicle has been taken to the same authorized Acura dealership at least twice specifically for this unintended braking problem. The dealership has performed software updates or other software-related service in an effort to correct the problem, but the unintended braking has continued. The

The shark-fin antenna housing on my Acura ZDX appears to have a defect in the way it is secured to the vehicle. The housing can separate from the roof during normal vehicle operation, creating a road hazard and potentially striking another vehicle, cyclist, or pedestrian. I reported the issue to Acura, but the company stated that the repair was not covered under warranty. I have found reports from other Acura ZDX and Honda Prologue owners describing the same failure. Although some dealerships have covered the repair, replacing or reattaching the housing does not necessarily correct the underlying design or retention defect. Because this component can detach from a moving vehicle and become a projectile, I believe it presents a legitimate safety risk. I am requesting that this issue be investigated to determine how widespread it is and whether a recall or redesigned attachment method is necessary.

Approximately three weeks ago, following a manufacturer-issued software update, the AcuraLink connected services app stopped functioning on my 2024 Acura ZDX. This outage has disabled OnStar-connected safety features including remote monitoring and emergency/roadside assistance connectivity and concerned there were other technology issues that may affect this, but I’m not aware exactly all of them. Additionally, none of the remote features work. This vehicle is an electric vehicle and there is no ability to monitor the status of the battery charge or to monitor the battery. Given the amount of technology in this electric vehicle the fact that the remote functions are not working presents a severe safety problem. I have contacted both OnStar and Acura customer support multiple times; both confirm awareness of the outage issue but have provided no fix or timeline. Both companies have taken no responsibility and their communication is terrible.The outage began around August 3, 2026 and remains unresolved as of August 20.

CONTEMPORANEOUS NOTE 2024 ACURA ZDX – AWD - NHTSA Recall No. 26V306000 Date: XXX Time: 12:25 PM On XXX at approximately 12:25 PM, I contacted Miami Acura Service at [XXX] to schedule the recently issued rear-view camera safety recall 26V306000 for my 2024 Acura ZDX. I was advised by the dealership representative that no appointments were being scheduled for the recall at this time because the required parts and tools had not yet been received by the dealership. As a result, I was unable to schedule the recall repair. However, she said she would take my number and put me on a waiting list when the hardware came in. Today is XXX and I have not been contacted by the dealer for this safety recall. I am still experiencing other intermittent issues that are non-related and have not been identified by Acura: ghost braking, improper shift status, collision mitigation without anything around, conditions not ready to shift, press start button and try to shift and gears are frozen. This was brougth to the attention of the Service Dept at Miami Acura and here we are 4 month later the vehicle is experiencing intermittent issues and the Safety Recall has not been applied in over 45 days.

The contact owns a 2024 Acura ZDX. The contact received notification for NHTSA Campaign Number: 26V306000 (Back Over Prevention); however, the part to complete the recall repair was unavailable. The contact stated that the manufacturer exceeded a reasonable amount of time to perform the recall repair. The dealer was contacted and confirmed that the part was unavailable. The manufacturer was made aware of the issue. The contact had not experienced a failure.

The contact owns a 2024 Acura ZDX. The contact received notice of NHTSA Campaign Number: 26V306000 (Back Over Prevention). The contact stated that while in reverse(R), the rear-view camera became inoperable with a red or yellow caution sign displayed on the screen. Additionally, the contact stated that while the vehicle was in reverse(R) on several occasions, the electric side mirrors rotated down, and the driver could see objects and other vehicles behind the vehicle. The vehicle was taken to a dealer, and the contact was informed that a software update was needed. The software update was performed, but the failure persisted. The vehicle was diagnosed another time, and it was determined that the rear-view camera and an unknown part needed to be replaced. The vehicle was not repaired. The contact stated that on one occasion, after the dealer visit, while in reverse(R) with the rear-view camera displaying a blank screen, the vehicle reversed into another parked vehicle. The contact had to physically turn while reversing, but did not see the vehicle. There was no injury sustained. A Police report was not filed. The other vehicle sustained minor damage. The manufacturer was not notified of the failure. The failure mileage was approximately 11,915.

The braking system does not engage properly and is worse in the rain. When adaptive cruise control is on, the car does not slow down at every instance when there is a car in front slowing down. When the car finally realizes there's an object/car in front it then slips before engaging in traction control, which seems to make the car actually slide forward rather than attempting to stop immediately.

My 2024 Acura ZDX has an intermittent braking-related malfunction that causes the vehicle to jerk unexpectedly while slowing or stopping. The problem has occurred in stop-and-go traffic, on hills, and while reversing. The exact cause is UNKNOWN. This creates a serious safety risk because the vehicle does not always respond smoothly or predictably when braking. In traffic, the sudden jerking could cause a rear-end collision or make it difficult to maintain a safe stopping distance. On hills or while reversing, the unpredictable movement could cause the vehicle to strike another vehicle, pedestrian, cyclist, child, or object. The vehicle has also experienced unusually rapid battery depletion, raising concern that it could become disabled unexpectedly in traffic, severe weather, or an unsafe location. Any relationship between the battery issue and the braking problem is UNKNOWN. The vehicle has been taken to authorized Acura dealerships multiple times, including Acura of Westchester and Curry Acura. The condition was reported repeatedly. The dealers stated they could not duplicate it, even after an extended road test of more than 300 miles. No permanent diagnosis or repair was provided, and the problem remains unresolved. Acura/American Honda was notified and opened a corporate case. There were no consistent warning lights or dashboard messages before the incidents. Because the malfunction is intermittent and may occur without warning, I cannot predict when the vehicle will jerk

My 2024 Acura ZDX A-Spec is impacted by the NHTSA Campaign Number 26V112000 (blank instrument panel/rearview camera). I took the vehicle to the dealership for the recall software update. The service invoice explicitly states: 'software update due performed software update on vehicle A11.' However, the update did not actually apply. The A11 module update is supposed to transition the infotainment system from Android 12 to Android 14 to resolve the safety issue. My vehicle is still stuck on Android 12, and Acura has incorrectly advised me that my trim does not get the update. The dealership's diagnostic tools are falsely reporting that the A11 safety recall update was successfully completed when it has not been, leaving my vehicle's camera and instrument panel vulnerable to failure. I have attached the service invoice as proof of the failed repair attempt. I have contacted Acura Customer Relations multiple times and advised that the recall is not complete. They have marked the recall update as complete.

On [XXX] at approximately 700 miles on a 2024 Acura ZDX A-Spec AWD (VIN [XXX] ), the Collision Mitigation Braking System (CMBS) failed to engage during a collision event. The system did not provide forward collision warning and did not initiate automatic emergency braking before impact. The collision resulted in minor damage to my vehicle. There were no injuries. CMBS is a manufacturer-installed automatic emergency braking system designed and marketed as a primary collision-avoidance safety feature; its failure to engage in an impending-impact scenario is a safety-critical defect. This CMBS failure is one of multiple safety system defects on this vehicle. Beginning at approximately 200 miles, the rear Advanced Driver Assistance System (ADAS) developed progressive failures, including: Rear Cross Traffic Alert and Rear Park Assist intermittently non-functional Blind Spot Monitoring failures on both left and right sides (DTCs U197A-00 confirmed by independent pre-repair diagnostic scan) A stress-cracked rear parking sensor housing A factory wiring harness routed incorrectly from the vehicle side, causing mechanical tension on the rear parking sensor connector and mounting bracket (confirmed in writing by the Acura dealer service manager on Repair Order [XXX][ dated February 25, 2026) American Honda Motor Co. (AHM) refused to honor the factory warranty, asserting without supporting forensic evidence that the defects were caused by an unspecified "outside influence" or "third-part

This is the most recent time that the automatic brake on my car kicked in for no reason. It has happened several times and I have made Acura aware of it, but this is the first time it has almost caused an accident because the car behind me almost rear-ended me. A Similar incident happened last year and I brought it in and they did nothing since they could not replicate it. I let the dealership know that there is a recall associated with this and they said that my VIN number does not match any recalls. I made it very clear to them that it is a safety issue and that it needs to be looked into in more depth in the only response they gave me was that sometimes the automatic brakes can be triggered by items that look like bicycles or people. In this case, there was a car in front of me and a car behind me, neither of which look like a bicycle or a person. It happened so quickly and so suddenly that I am not sure if any lights came on. The Acura client relations team so far has not been able to get a hold of a manager at the dealership and this remains unresolved.

The contact owns a 2024 Acura MDX. The contact stated that while driving at approximately 10 MPH and coming to a stop, the ABS activated unexpectedly and released brake pressure in the service brake system. The contact stated that the vehicle unexpectedly came to a complete stop. The dealer was contacted. The vehicle was not diagnosed or repaired. The contact stated that the failure was associated with NHTSA Campaign Number: 24V614000 (Service Brakes, Hydraulic); however, the VIN was not included in the recall. The manufacturer was made aware of the failure. The failure mileage was approximately 10,080.

Was trying to unlock the vehicle but it wouldn’t unlock the doors with the remote. Had to crawl through the trunk to access the car. Got a “door latch system service” maintenance error on the screen after the dealership had “fixed” it. This is a huge safety concern as this car is electric and if it does not unlock from the inside, can cause the passengers to be stuck in the car.

Incident Date: [XXX] Location: Miami, FL, USA What happened: On [XXX], in Miami, Florida, I brought my 2024 Acura ZDX to a complete stop on a flat surface, applied the brake, and then selected Park (the “P” indicator was illuminated on the instrument panel). After selecting Park, I opened the driver’s door and exited the vehicle. While I was outside the vehicle and no one was in the driver’s seat, the vehicle moved backward on its own and struck another car. I did not press Reverse or command any additional gear change after selecting Park. The vehicle had been fully stopped before Park was selected. No injuries occurred, but property damage resulted. This incident created a significant safety concern because the vehicle moved while unattended after Park was selected. I am reporting this event for safety documentation and investigation. INFORMATION REDACTED PURSUANT TO THE FREEDOM OF INFORMATION ACT (FOIA), 5 U.S.C. 552(B)(6)

My husband was driving on a small road and we were going about 25mph when he tapped the brakes the car jumped forward and the brakes did not catch. We lunged forward almost crashing into another car. No warning lights appeared. Driving conditions were normal, dry roads. Brought it into the dealership again for the same issue that we brought it in for less than 30 days ago.

On Sunday, February 15th at approximately 9:00 AM EST, I took my vehicle to Wash Co Car Wash (1020 Dolsontown Road, Middletown, NY 10940). This was the first and only time I have taken this vehicle through a car wash since beginning my lease in July 2025. It is important to note that this specific car wash is one for which my local Acura dealership provides service coupons during routine maintenance visits. As a loyal Acura customer, this reasonably implied that the facility is appropriate and safe for Acura vehicles. While inside the automatic wash tunnel, the roof-mounted shark-fin antenna assembly detached completely. There were no prior issues, no visible damage, and no warning signs before entering the wash. The following day, February 16th, I brought the vehicle to my local Acura dealership for inspection. After diagnostics, I was presented with an estimated $1,700 repair cost. This incident is particularly concerning because it is not the first issue I have experienced with this vehicle. Since beginning my lease in July, I have brought this ZDX to the dealership for service on three separate occasions to address different concerns. For a vehicle that is less than a year into its lease term, this pattern of service visits raises legitimate concerns about quality, durability, and reliability. Given the severity of the cost and the nature of the failure, I contacted Acura Client Relations in an effort to resolve the matter directly and professionally. After more than 48 h

2024 Acura ZDX Collision Mitigation Brake System will activate without warning engaging the parking brake. Has occurred intermittently while driving forward or in reverse. Dealership claims there are no codes and has advised that both front and rear systems should be disabled. Manufacturer states there are no software updates to address this issue. Failure milage approx. 100.

I was driving my 2024 Acura ZDX at approximately 50 mph on a rainy day and activated the rear windshield wiper. Upon activation, the rear wiper assembly detached from the vehicle and flew off while the vehicle was in motion. Fortunately, there were no nearby vehicles at the time; however, the detached wiper could have struck another vehicle or created a road hazard. The failure also resulted in loss of rear visibility during inclement weather. I contacted the authorized Acura dealer immediately. The dealer declined to inspect the vehicle or perform a warranty repair, stating that they could not proceed because the detached part could not be produced. The part was lost as a direct result of the failure. I provided photographs showing the location on the vehicle from which the wiper detached. The incident occurred less than six months after purchase, with fewer than 2,000 miles on the vehicle. I then contacted Acura corporate support. After an extended review period, Acura offered only a partial “courtesy” discount rather than a warranty repair for what appears to be a safety-related defect. I am reporting this incident due to the risk of detached exterior components becoming road debris and the associated safety hazard to other motorists.

1. What component or system failed or malfunctioned, and is it available for inspection upon request? The failed component is the drive motor inverter cooling system, specifically the drive motor inverter cooler (OEM part number 87821986). This component is responsible for regulating temperature within the high-voltage electric drive system. The vehicle is currently at the dealership with the repair order open, and the part has not yet been replaced due to national backorder status. The vehicle and failed component are available for inspection upon request. 2. How was your safety or the safety of others put at risk? The failure triggered a “High Voltage System Warning” message. This warning indicates a malfunction within the electric propulsion system, which controls vehicle movement and power delivery. A malfunction in the inverter cooling system can lead to: Loss of propulsion Sudden power reduction Vehicle shutdown while driving Potential overheating of high-voltage components Because this is a $75,000 electric performance vehicle with only approximately 5,100 miles and four months of ownership, a critical high-voltage system failure creates a serious safety concern. I do not feel the vehicle is safe to operate, and I have refused to drive it under these conditions. 3. Has the problem been reproduced or confirmed by a dealer or independent service center? Yes. The issue was diagnosed and confirmed by an authorized Acura dealership service department on January 29, 2026. Th

I am submitting this complaint regarding a significant safety-related failure in my 2024 Acura ZDX that occurred immediately after a dealer-installed software update. After my vehicle received a software update performed by an authorized Acura dealership, the entire infotainment system became inoperable. I was subsequently informed that the update caused a complete failure of the unit and that full replacement of the infotainment module is required. As a result of this failure, the following systems are nonfunctional: Hands-free Bluetooth (unable to make or receive calls legally and safely while driving) Audio/radio system Navigation system Climate control interface (controls integrated into the display) Phone charging capability The loss of hands-free Bluetooth functionality presents a direct safety concern, as drivers are required in many states to use hands-free systems while operating a vehicle. Additionally, the inability to access navigation and certain vehicle settings increases driver distraction. The climate control integration within the infotainment display further compounds safety concerns. These systems were fully operational prior to the dealership performing the software update. A routine manufacturer-issued update should not result in total system failure requiring hardware replacement. I am concerned that this issue may represent a broader defect affecting other vehicles equipped with the same system. I request that this incident be reviewed for potential saf

I’m reaching out regarding a serious vehicle incident that occurred in September 2024 involving my 2024 Acura ZDX. The vehicle i am leasing, accelerated forward into our property under circumstances that remain unclear and crashed into our garage, tearing down approximately half of the structure. During the event, the vehicle struck my girlfriend, causing her to sustain significant injuries, including a fractured femur, fractured tailbone, and a T12 compression fracture. There are several concerns regarding potential failure of vehicle safety systems, including lack of automatic emergency braking activation and no emergency call initiation. The vehicle remains in my possession and has not been repaired. I would like to explore whether a mechanical defect, unintended acceleration issue, or safety system failure may have contributed to the incident. Please let me know if you are available to review this matter. I can provide photos, documentation, and access to the vehicle for inspection.

I am filing this complaint due to a persistent and dangerous safety defect in my 2024 Acura ZDX. Since January 2025, the vehicle has suffered from recurring heating system failures. This has happened multiple times throughout the year, each time I have had this issue I have taken the vehicle to the dealership and have documented records that are verifiable. The issue most recently occured, on January 21, 2026, the heater failed and was blowing ice cold air, during a winter with 'Real Feel' temperatures of -25°F. The manufacturer has refused mechanical repairs (claiming it is a 'software issue') and has suggested I simply 'charge the car every time I stop' to generate heat. This is an inadequate technical remedy for a life-safety issue, especially as I transport three small children. The dealership is currently demanding the return of their loaner vehicle, which would leave my family stranded in dangerous, sub-zero conditions. My vehicle meets the statutory presumption of a Lemon under the New Vehicle Buyer Protection Act because it has been out of service for over 30 business days. Manufacturer: American Honda Motor Co. (Acura) Model: 2024 Acura ZDX (EV) Defect: Complete failure of the heat pump/HVAC system in sub-zero temperatures. Mediation Start Date: April 2025 (Exceeds 9 months without resolution), I was finally assigned a mediator in December 2025 only after sending emails to Acura executives. Current Status: Vehicle is currently out-of-service at the dealership, the de

I am reporting a safety concern involving delayed brake engagement on my 2024 Acura ZDX RWD. During normal braking, the brakes do not respond immediately. The vehicle slips and launches forward several times before braking force applies, and the traction control system activates prior to adequate deceleration. It feels like the brakes aren't catching properly. This condition occurs consistently and repeatedly, including on dry pavement, and is worse on wet pavement. It is not intermittent and does not require hard or emergency braking to occur. The delayed braking response creates a loss of braking confidence and presents a safety risk, particularly in traffic or during routine stops. I am concerned this may involve the brake control system, regenerative braking transition, or stability/traction control integration.

Acura TSB 25-033 details how dealerships or independent shops should update the infotainment unit (a11). When followed correctly, the update causes the infotainment unit to fail. This leaves the vehicle with no hands-free safety and GPS functions, in addition to no radio. Acura cannot replace the radio unit, rendering hands-free safety features useless.

The contact owns a 2024 Acura ZDX. The contact stated that while driving at slow speeds and driving over a bump or an object in the roadway, the brake pedal would depress to the floorboard. The contact stated that upon approaching an object once the brakes had failed, the Automatic Emergency Braking system would activate, and the ABS and traction control warning lights would illuminate on the instrument panel. The contact had taken the vehicle to the dealer on several occasions for repairs, but the dealer failed to duplicate the failure. The manufacturer was notified of the failure and provided a case number. The contact had been working with the manufacturer through arbitration for a buyback of the vehicle. The vehicle was not repaired and remained with the dealer. The failure mileage was approximately 15.

The contact owns a 2024 Acura ZDX. The contact stated while driving at various speeds, the Collision Mitigation Braking System (CMBS) activated the Automatic Emergency Braking (AEB) erroneously. There was no warning light illuminated. The contact stated that the failure occurred more frequently while reversing and occurred intermittently while driving forward. The contact stated that his wife also owned the same model vehicle, which had experienced the same failure. The contact had taken his wife's vehicle to an unknown local dealer, where it was suggested that the Forward Collision Avoidance system should be disabled. The contact had not taken the vehicle to the dealer to be diagnosed. The vehicle was not diagnosed or repaired. The manufacturer was informed of the failure. The failure mileage was approximately 200.

The vehicle was not diagnosed or repaired by an independent mechanic or dealer. The manufacturer was made aware of the failure, and a case was filed. The failure mileage was approximately 200.

The contact owns a 2024 Acura ZDX. The contact stated that while driving 35-40 MPH and depressing the brake pedal, the brake pedal went down to the floorboard, and the vehicle slightly responded, causing the braking distance to be extended and the vehicle drove through the red traffic light before stopping. There was no warning light illuminated. The contact was able to continue driving. The dealer was contacted, and an appointment was scheduled for a diagnostic test. The vehicle was not diagnosed or repaired. The manufacturer was not notified of the failure. The failure mileage was approximately 11,000.

On Wednesday, [XXX], I was driving near an intersection. There was a vehicle in front of me; however, they were accelerating as was I and at approximately the same speed. For no apparent reason, the automatic emergency braking activated and slammed on the brakes for absolutely no reason. This not only scared myself, but my [XXX] daughter in the back seat, and we almost were rear-ended by the car behind us. It was almost as if I was "brake-checking" the person. Both my daughter and I complained of neck pain (almost felt like whiplash) as well as a headache following this incident. There was absolutely no warning that this was going to happen. There were no messages, lights, or any other issues at the time. While this incident has only happened one time, it has happened one time when the vehicle has less than 3,000 miles on. This can quickly become an issue of someone getting rear-ended, or potentially even a road rage situation. INFORMATION REDACTED PURSUANT TO THE FREEDOM OF INFORMATION ACT (FOIA), 5 U.S.C. 552(B)(6)

While moving about 40mph, the emergency brake engaged and it slowed car down significantly. However, there was nothing in front of me. I turned emergency braking off due to this issue. Also, during raining day, when backing out of driveway, car's emergency brakes engaged. This happen twice.

Multiple times, while both reversing and driving forward, the vehicle has initiated hard emergency braking maneuvers when no emergency exists -- no rear or front cross traffic, no pedestrians. This is dangerous and could initiate a crash with other cars following the vehicle.

When hard braking the car doesn’t stop, you can feel the wheels lock up and it slides forward. Some times when stopping at slow speeds the car will lunge forward. I almost hit a car, went in an intersection and one time almost hit a person and I was only going 5-10 mph that time and I hit the brakes and the car slid forward. I am really scared and Acura says they test drove mine and a new one and they both do it so there is nothing wrong with it.

When backing up the car will slam on its brakes when there is NOTHING behind me. Most of the time it is when I am backing out of my driveway it will do it 2-3 times when nothing is there. It has done it a couple of times backing out of a parking space when nothing is there. I reported this to Acura but they didn’t do anything about it.

The forward collision warning and forward collision braking malfunctioned several times triggering false warnings and unnecessary hard braking. My safety was put at risk because the vehicle came to an abrupt, violent stop while in traffic and applied the parking brake. This action not only caused items in my vehicle (e.g., phone, water bottle, sunglasses) to fly to the front of the car and land in the footwells, but also hurt my neck and head from the severe and harsh movement. Additionally, this sudden unpredictable full stop creates a very high risk of the vehicle following me rear ending my vehicle, resulting in further injury and property damage. The problem has not been reproduced or confirmed by a service center as I have not had time to bring the vehicle in for service yet. The vehicle or component has not been inspected by the manufacturer, police, or insurance representatives. There were not any warning lamps, messages or other symptoms of the problem prior to the failure. However, the emergency brake warning has triggered several times without activating the brakes.

The automatic rear braking system on my 2024 Acura ZDX engages unexpectedly and without cause. It happens regularly when reversing, even though there are no obstacles, people, or vehicles behind the car. The sudden braking is jarring and creates a real safety concern, especially in traffic or tight spaces. I took the vehicle to my local Acura dealership, but they had no information or guidance on the issue. Despite this, many other ZDX owners are reporting the exact same problem on forums like Reddit, AcuraZine, and Facebook groups. This is clearly not an isolated incident and should be investigated immediately. The system is too aggressive and unreliable in its current state. It poses a risk of causing accidents or injuries. Acura must address this issue with a software update or recall before someone gets hurt.

On several occasions the car will violently stop as if we have crashed into something but there is nothing there. There is no warning before this happens even though we have the alert setting turned on. This has happened while we are reversing and moving forward. This puts us (driver and passengers) at risk because it is such a sudden and violent stop that it hurts our bodies (neck/back) and it is very stressful. It has not been reproduced or confirmed by the dealership yet

The following diagnostic tip was issued by the NHTSA for the Cadillac Lyriq (same vehicle as Acura ZDX): PIC6537A The Acura ZDX has the same issue and there are multiple forum posts online. However Acura dealers are claiming there is no bulletin / fix from Acura. The AC compress which also functions as a heat pump vibrates and shakes the entire vehicle. This system may be responsible for battery temps as well, Im not sure. If that is the case it is very important so battery temps are regulated and fires don't happen.

I am writing to report a serious safety defect in my 2024 Acura ZDX concerning the Forward Collision Alert and Automatic Emergency Braking. The system exhibits hyper-sensitivity, leading to unwarranted and dangerous automatic braking events. On 3/17/25, at approximately 4pm PT, I was driving my Acura ZDX on US 101 at 65 mph. A vehicle in front of me changed lanes into my lane. There was ample space between my vehicle and the vehicle that changed lanes. However, the Automatic Emergency Braking engaged the brakes forcefully, bringing my vehicle to a complete stop in the middle of the freeway. The vehicle essentially stalled for approximately 5-10 seconds, and I was unable to accelerate or move forward during this time. This created a highly dangerous situation, as I was vulnerable to being rear-ended by oncoming traffic. This incident occurred even though I had disabled the Forward Collision Mitigation System through the vehicle's settings. The system's behavior indicates a severe malfunction or design flaw, as it overrides the driver's intent and poses a significant safety risk. The fact that the system engaged the brakes when it was supposed to be disabled is very concerning. This hyper-sensitivity and the inability to fully disable the Emergency Braking System are critical safety issues that could lead to serious accidents, injuries, or fatalities. I request that the NHTSA investigate this matter immediately.

When you activate the turn signal to go right and complete the turn the signal snaps back so hard it auto activates the left turn signal. This occurs even when manually turning the signal on and off

I am submitting this complaint regarding serious safety issues with my vehicle. After a recent 180-mile trip, the car initially functioned without issue during local driving. However, on the morning of February 16, 2025, I encountered multiple warning messages at startup, including "Service Brake Assist," "One Pedal Driving Unavailable, Use Brake for Stopping," and "AUTO HOLD Unavailable." These warnings indicate potential braking system failures, which raise major concerns about the vehicle’s safety and reliability. Additionally, several key safety features became inoperable, including Adaptive Cruise Control and Acura Watch 360 (Supercruise). These features are critical for safe highway driving, and their unexpected failure compromises the vehicle’s performance and driver assistance capabilities. The fact that these systems became nonfunctional without warning creates a hazardous driving condition. Further compounding my concerns, the vehicle emits an electric, clicking sound when the brake pedal is depressed. This noise originates from under the dashboard near the steering column and suggests a possible malfunction in the braking or electronic control systems. Given the nature of these warnings and the potential risk of brake system failure, I am deeply concerned that the vehicle is unsafe to drive. I am seeking immediate resolution and will be bringing the car in for service as soon as possible. I urge the NHTSA to investigate these issues, as they pose a significant risk

Traveling 10-15 MPH on street when car immediately stopped/braked and message on screen said something like “forward brake assist applied” or something like that. There was ABSOLUTELY NOTHING in front of me. Thank god there was no car immediately behind me or I would have been rear-ended

The parking brake continously engages when in reverse disabling the vehicle until you manually release it. This happened 6 times and I was not able to safely back out of a parking lot and had to call for a tow truck to take vehicle to dealership. Dealership scanned vehicle for codes but could not find an issue and told me that is part of the safety features. Not sure how safe it is to engage the parking brake 6 times and cause my vehicle to be in traffic. There were no obstructions around the car, so I feel this is a very dangerous malfunction.

The contact owns a 2024 Acura ZDX. The contact stated that while depressing the manual regenerative brake lever the braking system failed to activate and the driver had to depress the brake pedal to stop the vehicle. The contact stated that during the failure the message "Service Brake Assistance" was displayed. The contact stated that the BRAKE Hold feature and Adaptive Cruise Control were inoperable, and there was a ticking sound while depressing the brake pedal. The vehicle was taken to the dealer who reprogrammed an undisclosed software, but the failure persisted. The vehicle was returned to the dealer. The manufacturer was notified of the failure. The failure mileage was 320.
