2021 Honda Pilot complaints

The contact owns a 2021 Honda Pilot. The contact stated that while the engine was idling and with the gear shifter in the park position, the contact reached into the vehicle from the front driver's door, and suddenly the vehicle began to slowly roll backwards. The contact was pushed to the ground, causing the front driver's side wheel to roll over the contact's right leg. The vehicle continued to roll backwards before making a U-turn and then rolling forward down the inclined street and increasing speed. To avoid having the vehicle roll down hill into a crowded street with pedestrians, the front passenger inside the vehicle turned the steering wheel, causing the vehicle to crash into the rear of another parked vehicle. During the incident, the contact suffered an injured right leg and was transported to the hospital. A police report was taken at the scene, and the vehicle was towed away. The both air bags had deployed, and the vehicle was destroyed. The contact indicated that during the incident, the emergency brake was not activated. The cause of the failure was not determined. The manufacturer and local dealer were not notified of the incident. The failure mileage was 20,000.

I am submitting this complaint to formally report a serious and widespread safety defect involving the front-facing camera system on my 2021 Honda Pilot. This defect has resulted in multiple safety system failures and has placed myself, my passengers, and other motorists at unacceptable risk. The front camera on my vehicle does not function as designed, which has caused the complete loss or repeated failure of critical safety features, including adaptive cruise control, lane keeping assist, lane departure mitigation, collision mitigation braking, and other forward-facing driver assistance and alert systems. These systems are not optional or convenience features. They are advertised and sold as essential safety technology intended to reduce accidents, mitigate driver error, and protect human life. Their failure substantially impairs the vehicle’s safety performance and creates a foreseeable risk of serious accidents, injuries, or fatalities, particularly during highway driving or emergency situations. When I sought assistance from the dealership, I was informed that Honda would not cover the repair because the vehicle exceeded a mileage threshold. This rationale is unreasonable and misleading. A front-facing camera is not a wear-and-tear component and has no logical connection to mileage accumulation. It is an electronic safety system whose premature failure suggests a defect in design, materials, or manufacturing. I then contacted Honda directly, and the manufacturer again re

While my husband was taking our daughter to school on 01/05/2026 around 6:00am, a warning message flashed on the radio screen: "EMISSIONS SYSTEM PROBLEM: The engine is not operating properly. Avoid high speeds and visit your dealer as soon as possible. If the indicator is blinking, stop in a safe place where there are no flammable objects. Turn off the engine for 10 minutes or more to let it cool. Restart the engine. If the indicator continues to blink, immediately have your vehicle checked by the dealer. " This was a safety at risk for my husband, my child, and the public - anyone driving near the vehicle. My husband pulled over and called me to let me know what was happening. He called AAA to have the car towed to the dealer. And called the dealer to let them know we were having the vehicle towed to them. They diagnosed it with "a unit in need of engine replacement." The car was purchased as a certified pre-owned vehicle in 12/2021. It is a 2021 Honda Pilot and had a few hundred miles over 8000 at the time of purchase. The dealer is not taking responsibility as the miles 62,007 are just over the 60,000 mile powertrain warranty. And over the 5 years by weeks - 11/2020 to 01/05/2026. I was advised to contact American Honda. They basically told me I was not eligible for a goodwill assist as because: 1.) I was not the original owner 2.)I did not have my service done at Honda. However, I did have documents of all of the service that had been done and sent those receipts to the H

The auto-idle feature on this vehicle stalls out the engine on a regular basis, causing risk of accident from surrounding traffic. When breaks applied for red light, stop sign, traffic, etc., the auto-idle feature first engages and powers down the engine, however upon releasing the breaks, the engine stalls out, shifts into neutral, and the battery light comes on. I then have to get it into park and try to restart the vehicle. Sometimes it starts right away, other times it can take a few tries. Meanwhile, cars behind me are honking because I can't get my vehicle to move forward with traffic. Several times I have almost been rear-ended because the car behind me is expecting me to move forward when they see my brake lights turn off. I've talked to my dealer who informed me they completed a auto-idle recall software update in 2023 (recall #23-008) but the problem continues to happen. They have scheduled me to bring in the vehicle to look at the starter for potential replacement, I am hopeful it will not cost me a lot of money. THERE SHOULD BE A RECALL TO FIX THIS ISSUE! This is known issue on many Honda vehicles (there is a class-action lawsuit). It is also ridiculous that ther is no way to permanently disable the auto-idle feature. Thank you!

Check Engine Light came on during normal highway driving with Cylinder 2 Misfire as the readout. The vehicle was brought to local Honda dealer for troubleshooting and maintenance. Dealer maintained vehicle on schedule with 96,000 miles on it. Initially, informed us that this was due to the air filter housing being improperly placed and low power from the battery. Resolved both and then informed us it was an issue with the connecting rod/crankshaft and the engine would need to be replaced. During most recent fluids service about 2 months prior, had raised concerns about an intermittent shifting/low RPM jump and was told it was just debris but no real issue.

While driving the check engine light started flashing and lost a lot of power. Pulled over and turned the car off. Turned the car back on and the light was gone and power seemed to be back. Trying to get home about 15 minutes later every light came on. Lane assist, check engine, blind spot, traction control, literally all warning lights. When these came on the car lost all power within a minute. Wouldn't turn over or even power on to use lights or the radio. Got the car towed to two separate garages both stating engine failure. Honda dealer provided documentation of a bearing failure which damaged cylinder 5.

We were driving our 2019 Honda Pilot and at a traffic light the car failed to restart after the auto stop-start system shut off the engine. This happened when I started to step on the gas so we could have been rear-ended by the car behind us. The brakes also appeared stuck when I tried to depress them so I could restart the car. There was no warning until the car refused to start, but the computer system did appear to do some sort of a reboot sequence.

After I drove for 30 minutes and made a stop in a red light, the car automatically went to neutral position and I wasn't able to turn it back to driving or parking ( the brake locks) and I had to turn the car off for 10 seconds in the middle of the road and put my emergency lights on. After I turn it back on It worked normally.

Problems started showing on car a week ago. Tested battery and it was not holding a charge. Replaced battery and problem still persisted. Car is now at dealership and they are quoting close to $2000 due to failure for internal windshield camera. Car has right over 78k miles. This is a safety issue.

Car does not want to start even though the batter and alternator are good (tested by tow truck company). Restarts fine once batter is disconnected and then reconnected again. This has now happened twice.

I have had two major problems with this car. At approximately 84,000 miles, the engine started making a very loud noise, regardless of speed. It was first diagnosed by an independent service center as a control arm bearing failure. I contacted Honda Corporate and was told that it had to be diagnosed by a Honda dealer/service center. It was then diagnosed as a failure of the control arm bearing by a Honda dealer/service center. I was told the engine had to be replaced. Honda Corporate offered a 50-50 split, leaving me with a bill of $8480. This is completely unfair and unjust for me to have to pay this for a manufacturer's defect. In the second incident shortly thereafter, I was on the highway in traffic when the automatic stop-start function failed, and the car stopped and did not re-start. I had cars backed up behind me, and it was a very unsafe situation. After turning the car off completely, I managed to restart it, and got off the highway. The problem continued afterwards, and I had to turn off the function manually in order to drive the car at all.

While stopped at an intersection, the car died, the transmission shifted to neutral automatically and the radio would not turn on. The AGM battery was replaced approximately one year ago when a similar situation took place.

The front camera has malfunctioned after locking down the brakes on my vehicle. Without the camera, the automatic braking system, forward collision, lane departure, adaptive cruise control, and high beam are no longer functioning. While the high beams are not as big of a deal, the safety features such as the braking system and forward collision are of more significance.

The contact owns a 2021 Honda Pilot. The vehicle was serviced under NHTSA Campaign Number: 23V174000 (Visibility), but the failure occurred. The contact stated that the first time the driver's side mirror was replaced, the image in the mirror was distorted, severely compromising driver visibility. The contact stated that the mirror looked like it was made of plastic and not glass. The vehicle was taken back to the dealer. The driver's side mirror was replaced. The contact stated that the failure persisted. The vehicle was taken back to the dealer, and the driver's side mirror was replaced. The contact stated that the failure persisted. The contact stated that before the recall the driver's side mirror never experienced the failure. The manufacturer was not notified of the failure. The failure mileage was approximately 100,000.

Multiple safety features are failing on this 2021 Honda Pilot. At startup, I get the following errors: Collision Mitigation System Problem, Road Departure Mitigation System Problem, Adaptive Cruise Control Problem, Lane Keeping Assist Problem. Dealership says it is an infotainment system problem and it will cost about $1,200.

When driving and wanting to accelerate at 65mph car just because limp, won’t go when accelerating for a few seconds, speed drops, then you press back on the accelerator and after a few times the car goes back to normal. So, you loose control of the accelerator for a few seconds and you cant go faster, it just freezes and speed drops. This has been happen g for awhile. I even called Honda Corporate to advise them. It’s been happening for over 2 years. It comes and goes. We are starting to hear a clunk noise now.

The infotainment system screen would simply not illuminate when the car is started. Also the auto engine shut off, chooses not to restart the engine when your foot is removed from the break peddle.

The contact owns a 2021 Honda Pilot. The contact received notification of NHTSA Campaign Number: 24V064000 (Air Bags); however, the part to do the recall repair was unavailable. The contact stated that the manufacturer had exceeded a reasonable amount of time for the recall repair. The dealer was contacted. The manufacturer was not made aware of the issue. The contact had not experienced a failure.

The contact owns a 2021 Honda Pilot. The contact stated that the vehicle was repaired under NHTSA Campaign Numbers: 23V174000 (VISIBILITY), 24V064000 (AIR BAGS), and under TSB: 0101T0. The contact stated that the dealer did not repair all the recalls. The contact stated that in the driver’s side mirror, the image appeared wavy and resembled a funhouse mirror. The TSB regarding the coaxial cable terminal (FAKRA) was not repaired properly. The contact stated that when the vehicle was started there was an abnormal popping and crackling sound coming from the speakers. The contact returned the vehicle to the Service Department to have the vehicle re-examined; however, the dealer refused. In addition, the contact stated that the rearview camera displayed a distorted image while the vehicle was in reverse(R). The dealer stated that the camera was on fish-eye mode. The dealer switched the lens and cleaned the camera. The manufacturer was not made aware of the failure. The failure mileage was 84,436.

On multiple occasions the hazard mitigation system has picked up on hazards that aren't there causing rapid braking AND steering over correction. Currently the button on my vehicle that has an image representing the ability to turn the system off doesn't appear to be connected or working. I have always left the system on as it felt "safer" when I bought the vehicle new. I haven't even tried to turn it off until recently when the system seemed to start malfunctioning. Today (11/19/2025) while traveling the interstate for a routine doctor appointment the adaptive cruise control randomly shut off as I was driving multiple times. If I changed lanes and a vehicle was in front of me the adaptive cruise control would just shut off with no warning or alert rather than adjust the speed as the system is designed to do. Once I exited from the interstate at a traffic light (green, turning left) the lane assist overcorrected, the steering wheel got stiff and it was jerked into the other lane almost causing a collision. This is very concerning as I was very fortunate not to have been involved in a collision today thankfully the other driver was paying attention and evaded. Each incident there has been ZERO warning. There have been a couple times recently where the system randomly fails and says there is a problem, but within minutes come right back on and operates properly until it randomly malfunctions again. This has occurred very sporadically over the past 6 months with incidents rapidl

Vehicle is setting multiple faults for ADAS system. LKAS, ACC, collision mitigation system, auto high beam lights inoperable. Forward facing camera in the top of the windshield has failed.

While driving on the freeway at a slow speed due to two freeways merging, my Honda Pilot suddenly stopped/stalled. When I tried to restart the car by pressing the Auto Idle Stop button to vehicle did not start. It took three times of pressing the Auto Idle Stop button for the engine to restart. I am lucky that the traffic was going at a slow speed due to the merging of freeways so I was able to right away press my emergency signal lights on. I panicked and was scared for my safety and what could have happened to myself and others if the vehicle was running at a higher speed. This could have caused a major accident. Because this happened yesterday, I will be calling Honda to report the issue as well and have my vehicle inspected. My vehicle has had issues many times in the past with the Auto Idle Stop button not starting, however, it has never happened while driving. The concerning part as well is that the vehicle did not give any kind of warning light or message.

Upon startup, LKAS, ACC, FCW and brake lights are illuminated and the corresponding systems are non-functional. This failed with less than 50k miles and the car was ~3 years old. This is making the car less safe to drive because some of the safety systems are non functional. The basic cruise control also does not work.

Honda’s Auto Idle Stop system shuts vehicle off when at a full stop and fails to restart after removing foot from the brake. Instead, when you remove your foot off the brake, the vehicle switches to neutral or park and does not restart despite following on screen instructions to restart (Example: switch to park, put foot on the brake, and press start button). We have to put the hazard lights on and try the steps over and over again until it restarts. This is a major safety issue, especially when at a traffic light or in heavy traffic, where every second counts and you have to worry about someone not noticing that you are stopped or have hazard lights on and plows into you.

Transmission failed and car would no longer get into gears. It started when I tried accelerating on the highway and heard a whine The car would not accelerate. I tried again and this time it accelerated just fine. Made it home and the next day the car would turn on but not go into gears. The front panel showed warning of “Transmission Failed”, and “Engine trouble”. The dealership diagnosed that I needed a new transmission for $9,000! The previous day the car was working fine until and after that “whine” noise. I have not paid for repairs yet.

Wife was driving car and it stalled when slowing down for a red light. No check engine light or dash warning notices. Car then displayed instructions to restart the car Tried to restart 4 or 5 times. Finally started. We were lucky she was not on a highway driving at highway speeds.

UNKNOWN

Component inspected by Honda dealer It’s the forward camera it has already malfunctioned and no longer works I only have 62,000 miles on my pilot. This seems excessive there is definitely a defect in these vehicles. The incident is the warning lights that came up and no longer worked

While stopped at a traffic light the “Auto Stop” engine shut off feature engaged. When releasing the brake, the vehicle completely shut down, all dash lights came on as did the transmission mode lights. Upon trying to restart with the start button, prompts came up to place the vehicle in park. Trans select button did not work. Pressed the Start button several more times. At one time all dash lights went off, except for the battery light. Brake pedal went all the way down to the floor. Opened the drivers door and then tried the start button one more time with the AutoStart button switched off after dash lights returned. Vehicle started after that. Blocked traffic for one traffic light sequence. Occurred on Route 30 and Schoolhouse Road; New Lenox IL on 10/25/25. Attempted to restart several times afterward and vehicle restarted. Trying to drive with “autostart” feature manually turned off from now on, if I remember. Scheduled checkup @ dealer 10/29/25. Honda of Joliet Vehicle has slightly over 40k miles.

Per the mechanic the rod bearing broke into the engine and caused sudden engine failure. I was on a highway when this occured, thankfully I was already in the right lane and right before an exit to which I took and secured the vehicle in a safe location. It was extremely dangerous location for this to occur and thankfully no one was right behind me. There were no warnings or messages prior to the incident. It was just routinely serviced within the past month. I heard a loud clank, the engine light started flashing, and the car started to slow down, there was knocking sounds in the engine. We had it towed to D and M service center then moved to Gillman Honda service center. It was confirmed by two different shops, D and M service center at 1029 Pat Booker Rd, Universal City, TX 78148 and Gillman Honda dealership at 16044 I-35 N Selma, TX 78154 that the rod bearing cracked into the engine and metal shavings were identified in the engine oil.

Car is slow to start or doesn't start at all, particularly after frequent engine stops/starts or when engine has idled for a period of time. Battery has been replaced. Symptom comes and goes, but seems to get worse with frequent engine stops/starts (i.e., driving to different locations with short stays at each, or with the automatic engine shut off)

The contact owns a 2021 Honda Pilot. The contact stated that while attempting to reverse, the rearview camera became inoperable. The contact stated that the rearview camera image was blank. The vehicle was taken to the dealer, but was not diagnosed or repaired. The manufacturer was made aware of the failure. The approximate failure mileage was 55,000.

After stopping at a traffic light or stop sign the car's auto-stop/restart feature has failed multiple times to restart the engine. This has left the car stalled at a light and needing to manually place the car in park, turn off the electrical, then attempt to restart the vehicle. The problem started about 4 months ago and has been starting to happen more frequently.

The front camera which controls all of the safety features went out! 1 week ago. It has been confirmed and I am now having to pay almost $2700.00 to have it fixed. I am really upset to see how many issues this year of the car has. And the fact that Honda has known about it since 2019 and did nothing to fix them. There are 318 complaints on this car and I’m guessing over half of them have to do with the front camera. It is showing 5 safety codes.

My Honda Pilot experiences a serious safety issue with the Auto Idle Stop feature. When the system engages at a stop (such as a red light), the vehicle sometimes fails to restart, leaving me stalled in traffic. This creates a dangerous situation for myself and other drivers. The problem appears to be related to the Auto Idle Stop system and/or the auxiliary battery. Many other Honda owners are reporting similar issues, which suggests this may be a widespread defect that needs investigation. I just dropped the car at Honda dealership for further inspection

My 2021 Honda Pilot AWD (40,200 miles) shifting from Drive to Neutral at intersections by itself, then Engine dies. It happened multiple times. If you need more information, pls contact me at [XXX] INFORMATION REDACTED PURSUANT TO THE FREEDOM OF INFORMATION ACT (FOIA), 5 U.S.C. 552(B)(6)

The contact owns a 2021 Honda Pilot. The contact stated that while his wife was driving 50 MPH, the engine seized, and the functions on the vehicle became inoperable. After waiting for an hour, the vehicle restarted. The contact was unaware if there were any warning lights illuminated. The contact stated that on a separate occasion, while the contact's wife was driving 30 MPH, the engine seized. No warning lights were illuminated. After waiting for a long while, the vehicle was restarted. The vehicle was taken to another dealer, Honda of Whittier; however, no cause for the failure was found. The dealer restarted the vehicle. The contact stated that the failure persisted. The vehicle was not repaired. The manufacturer was not notified of the failure. The failure mileage was approximately 15,000.

The contact owns a 2021 Honda Pilot. The contact stated that the infotainment system had turned off unintendedly while driving. Additionally, the rearview camera image was black while reversing. The vehicle was taken to the dealer, where the contact was informed that the repair could not be covered under NHTSA Campaign Number: 23V431000 (Back Over Prevention), which was previously performed on the vehicle. The contact stated that the recall repair failed to correct the failure. The vehicle was not diagnosed or repaired. The manufacturer was not contacted. The failure mileage was approximately 48,000.

When stopped at a stop light the engine idle kills the engine and want start back up causing traffic backups...have to go through process to setting back to park and trying to start which does not happen quickly leaving people behind you frustrated and honking. This needs to have an option to disable it if you don't want that function as it's very frustrating and dangerous. Please get honda to fix issue. Thanks for your help.

Vehicle: 2021 Honda Pilot VIN: [XXX] Complaint: My 2021 Honda Pilot continues to have the same issues described in NHTSA Recall 23V-431 (backup camera / infotainment coaxial cable defect). The recall was marked “completed” about two years ago, but the safety problem persists. Symptoms include: •Infotainment screen going black •“Network communication lost” error messages •Backup camera flickering or failing to display Because the backup camera is federally required under FMVSS 111, my vehicle is not compliant with safety standards. The dealership told me that since the recall was already performed, I would now have to pay out of pocket for further repairs. This means the original recall remedy either failed or was not effective. I am filing this complaint because Honda and its dealership are refusing to correct an unresolved safety defect, leaving my vehicle unsafe to operate.

AFTER I had the softwear update! When idle at stoplight, auto idle feature kicked on. When light turn green and I pushed gas, car shut off entirely. This happened on multiple occasions. While waiting for an appointment to get this issue looked at, my car failed to start after being parked. It would not start after a jump from another vehicle. The tow truck driver was able to bet it jumped using a battery pack case. At the dealership, battery failed load test. Waiting to see if starter needs to be replaced and valves adjusted under extended warranty.

On the afternoon of Friday, August 29, 2025 while driving the Honda Pilot on a US Highway, the "Check Engine" light came on and the vehicle immediately experience a decrease in speed. Top speed on the highway suddenly became approximately 25 MPH and the Pilot became sluggish and was shaking. We had to drive with the vehicle's "flashing hazard lights" on due to the low speed on the 55 MPH highway speeds. Multiple alerts appeared on the vehicle information display panel. I was just able to get the vehicle home. Due to the Labor Day Holiday, we were not able to get the vehicle scheduled to go into the shop until the Tuesday following the Monday Labor Day holiday. It was very difficult to get the Pilot to start on the Monday "Labor Day" to drive to the automobile shop for them to look at it the next morning (Tuesday, September 02, 2025). Once it did start, it again displayed multiple alerts on the vehicle information display panel behind the steering wheel. Speed was again limited to a maximum of 25 MPH. While driving to the shop (less than 5 miles away), the engine stopped completely and the car shifted out of the "Drive" mode and switched into Neutral without any action of the driver to do so. We had to coast into a nearby parking lot to get the vehicle out of the active city road. All attempts to restart the vehicle in the lot failed. We had to call for a tow truck with a flat bed to take the AWD Pilot to the local shop. While in the shop the codes were diagnosed by the attach

When using Apple CarPlay (wired or wireless), audio intermittently skips and stutters like a skipping CD or static AM radio. This only occurs on CarPlay, not Bluetooth. The skipping can make navigation prompts and hands-free calls unintelligible. Bluetooth audio works fine. Concern: The infotainment/head unit system may be part of the known MOST bus / FAKRA connector issue documented in Honda TSB A20-058 (which covers 2019-21 Pilot/Passport). Although my VIN shows no recalls, the behavior suggests a communication defect in the infotainment system. Safety relevance: This impacts driver attention and safety, since distorted CarPlay audio interferes with navigation directions, voice calls, and Siri prompts. It forces the driver to look down at the phone more frequently, which increases distraction.

I have two issues. First issue is the car will hit an intermediately not start once shut off and will take a few times of making sure the car is completely shut off opening your doors letting it power down before being able to restart. The next issue is the forward collision notification will randomly beep at every car that goes by specifically white cars. And also the adaptive cruise control brakes a little bit harder than expected.

The contact owns a 2021 Honda Pilot. The contact received notification of NHTSA Campaign Number: 24V064000 (Air Bags). The local dealer was contacted regarding the recall and confirmed that parts were not yet available for the recall repair. The vehicle was not diagnosed or repaired. The manufacturer was not contacted. The contact had not experienced a failure.

Dash warning lights come on for Lane keeping assist, collision mitigation, ACC, brake system, auto high beam.

Car does not restart after auto start stop is engaged, car stalls at intersections, causing dangerous conditions.

The contact owns a 2021 Honda Pilot. The contact stated that while at a complete stop with the START/STOP feature activated, the engine shut off while depressing the accelerator pedal. There was no warning light illuminated. After waiting for several minutes, the contact had to perform several procedures to restart the vehicle. The vehicle was initially taken to a dealer where a software update was performed; however, the failure returned weekly. Recently, the contact stated that upon restarting the vehicle after the failure, the vehicle began to jerk while accelerating, with an abnormal tapping sound coming from the engine. The vehicle was taken to a dealer and was diagnosed with a defective engine rod bearing. The contact was informed by the mechanic that the repair could not be warranted. The vehicle was not repaired. The manufacturer was notified of the failure but offered no assistance. The contact was referred to the NHTSA Hotline to report the failure. The vehicle was not repaired. The failure mileage was approximately 15,000.

My 2021 Honda Pilot SE has developed a failure of the forward-facing Multipurpose Camera Unit (mounted behind the rearview mirror). A scan with a professional tool confirmed Diagnostic Trouble Code U3000-49 – “Multipurpose Camera Unit Internal Electronic Failure.” When this occurs, the vehicle immediately displays multiple warning lights at every startup: Collision Mitigation Braking System (CMBS), Lane Keeping Assist (LKAS), Road Departure Mitigation (RDM), Adaptive Cruise Control (ACC), and Automatic High-Beam/Dimming headlights. In addition, the dashboard shows a “brake system failure” message, although the brakes continue to function normally. This single camera failure disables all of Honda’s Honda Sensing crash-avoidance features, leaving the driver without forward collision prevention or lane-keeping systems. The failure is persistent, and the DTC remains “Current” after clearing. I took the vehicle to a Honda dealer, but because the car is out of warranty they refused to perform diagnosis or provide a repair estimate, essentially telling me it was my responsibility to resolve. This problem is widely reported by owners of Pilots, Odysseys, CR-Vs, Accords, and Passports, all showing the same U3000-49 code and symptoms. Independent shops confirm they often see these failures, and forums show repeated cases of owners paying high out-of-pocket costs, sometimes with parts on back-order. Honda has recalled less serious issues, such as rearview camera display faults, while th
