2019 Acura MDX complaints

After driving for an extended timeframe (approximately 3 hours, trip was traveling between Des Moines, Iowa and Kansas City, Missouri) at Highway/interstate speeds, upon slowing down from those speeds, the vehicle goes into limp mode and check engine light begins blinking. After pulling over and turning car off and on again, normal behavior resumes. This has happened both as I arrived in the Kansas City area, and upon my return home to the Des Moines area. Depending on circumstances for when vehicle enters limp mode, there’s a significant risk of causing an accident. Dealer was unable to pull any codes and therefore is unwilling/unable to address the issue.

The contact owns a 2019 Acura MDX. The contact received notification of NHTSA Campaign Number: 19V256000 (Exterior Lighting). The dealer was made aware of the issue, but the service manager initially refused to perform the recall repair free of charge due to the vehicle's salvage title. However, after the contact threatened to report the dealer, the dealer complied and repaired the vehicle free of charge under NHTSA Campaign Number: 19V256000 (Exterior Lighting). The manufacturer was made aware of the issue with the dealer. The contact had not experienced a failure.

In March, I made an appointment at Lehigh Valley Acura in Emmaus, PA 18049, to address NHTSA Recall Number 23V-751 on my 2019 Acura MDX. When I got to the appointment on [XXX], the service technician told me that American Honda will only send parts for recall-related repairs for cases where the "vehicle is showing evidence of the connecting rod bearing defect." Since the evidence of the defect is that the car could "stall while driving," I believe this sounds like a defect that should be addressed immediately. I called American Honda on [XXX], and was told that they don't have sufficient parts to fix all the vehicles covered by the recall. The person I spoke to said that we would get a letter in the mail when it is our turn. I believe this is negligence on the part of American Honda and Lehigh Valley Acura. How do I get this defect addressed immediately? INFORMATION REDACTED PURSUANT TO THE FREEDOM OF INFORMATION ACT (FOIA), 5 U.S.C. 552(B)(6)

Problems may occur intermittently, including during engine startup and while driving, with warning messages appearing on the dashboard： Auto High-Beam Problem, Road departure mitigation sysem problem,, Collsion mitigation system problem, Lane keeping assist problem and Adaptive cruise control problem. All of Advanced Driver Assistance Systems can't be used.

MULTIPLE OCCASIONS THE BRAKE COLLISION SENOR ACTIVATES WITHOUT AN OBSTACLE IN SITE. THE CAR WOULD SPONTANEOUSLY BRAKE AS THE WARNING SENSOR FLASHES ON THE DASHBOARD. NO RESULTING CRASH, BUT A FEW CLOSE INCIDENTS.

See attached document for complaint

Forward Collision Mitigation braking randomly activates and slams on the brakes despite no cars/obstacles/items in front of it. I have luckily not been rear-ended, but I've had several close calls when driving in traffic (car noses dipping behind me). The dealership has so far been unable to replicate this issue and stated that unless they can replicate there is nothing they can/will do to fix the issue.

Infotainment system randomly becomes unresponsive and the screens will go black. The dealership stated that my phone was causing the issue. This is not true as the issue has happened when my phone is not in the car, phone is in the car/connected via bluetooth, in the car/connected via apple carplay (wired connection). This could be dangerous during the summer as these screens control the temperature controls and some of the safety systems.

2 Issues: Transmission shifts hard between 35-50mph and 50-60mph. Dealership accused me of utilizing improper gas which is not factual; this car has only received the recommended premium octane gas since I purchased it as a Certified Pre-Owned vehicle. Recall: vehicle is currently under crank shaft recall. In the original notification, Acura stated parts would be available in April. Per the Acura dealer, Acura told them parts will not be available until October. This timeline is unacceptable for such a serious safety recall (risk of fire/crash). I feel unsafe driving this car and am worried I will not get fair market value with the recall still open.

The contact owns a 2019 Acura MDX. The contact received notification of NHTSA Campaign Number: 23V751000 (Engine and Engine Cooling). The contact stated while her nephew was driving at an undisclosed speed, he noticed smoke coming from the front and rear of the vehicle. No warning light was illuminated. The contact’s nephew pulled off the road to lift the hood of the vehicle where he saw flames. The Fire and Police Department arrived at the scene however, the fire had already been extinguished. The contact was unaware if a Police report was filed. There were no injuries. The vehicle was towed to the nephew’s residence where the Insurance Adjustor took pictures of the damages. The vehicle was towed to Mack's Automotive but due to the extensive damage, the vehicle was not repaired. The contact was informed by Mack's Automotive that the rod went through the engine causing the oil to leak which caused the engine to catch on fire. The vehicle was towed back to the nephew’s residence and remained unrepaired due to the cost and because the Insurance provider declined to pay to repair the vehicle because it was deemed a mechanical failure. The manufacturer was made aware of the failure and opened a claim; however, the contact had not spoken with the manufacturer personally. The failure mileage was unknown.

While driving the vehicle at highway speeds the accelerator pedal became unresponsive. Additional force on the pedal pushed it to the floor with no response from the engine. After letting off the pedal while trying to pull the vehicle over to a safe location along the road, a press on the pedal from fully released, caused the engine to rev up and propel the vehicle again. This has happened 3 times but is very random, and not easily reproducible. It is a very unsafe condition when it does happen as the vehicle loses speed, and the driver no longer has speed control!

Unknown, manufacturer says can’t be fixed. It MOST certainly can be fixed! They just don’t want to do it.

Engine had a knocking noise, went to dealer and explained the problem. They mentioned there was a recall regarding this issue but when my vehicle's Vin was typed in they said it was not part of the recall. A few days later all the warning lights in the instrument panel came on and soon after the engine went bad and had to replace it. My vehicle had approximately 45k miles when this happened. I was completely shocked, angry and disappointed with Honda Motors when they didn't want to take responsibility. It's obvious this was a manufacturing problem with these engines and they should reimburse vehicle owners that had issues with these vehicles. Thank you for your attention!

Beginning in October of 2023, I was hearing an engine knock/ticking. Acura tech support at the local dealership said my rear cylinder head needed to be replaced. I asked Acura how, since my car is only a few years old, could this cylinder head already be bad. They responded that these vehicles are mass produced by the hundreds of thousands and sometimes bad parts or installations slip through. I paid $7,500 for the new cylinder head, but now I see the new recall about engine crank shaft and the connecting rod bearing can wear and cause damage to the engine. It further says if you hear engine knocking, to immediately call Acura.

I was yielding to make a left hand turn , in the middle of the intersection, and my car turned off and wouldn’t turn back on. In addition the car occasionally jerks as I’m driving almost like if it changes gear. Sometimes I can’t get the car in park position I have to press the button multiple times. The recall going on right now can cause a fire crash or injury and they cannot replace the parts until April 2024 and I don’t feel safe driving my car.

Transmission is very laggy when stepping on gas pedal causing late takeoffs. It may damage internals. Also very hard shifting at certain speeds

The contact owns a 2019 Acura MDX. The contact stated that occasionally while accelerating, at a stop, or while driving, the vehicle lost motive power and stalled. While driving at approximately 50 MPH, the vehicle unintendedly accelerated to 80 MPH. Additionally, while driving at an undisclosed speed, the brakes activated independently. There were no warning lights illuminated. The vehicle was taken to the local dealer, who was unable to duplicate the failure. The vehicle was not repaired. Upon returning the vehicle, the warning lights were flashing or beeping without a light. The steering wheel was loose. The steering wheel also turned a third of the way, but the wheels failed to respond. The contact stated that the failure was related to NHTSA Campaign Number: 23V751000 (Engine and Engine Cooling). The manufacturer was contacted and opened a case. The failure mileage was approximately 36,000.

The back inner tail light on my car is not working, which is the following recall, however, according to acura, my vin does not apply and does not show a recall. I believe this is an error since I am having the exact issue and my vin should be included in this recall. NHTSA RECALL NUMBER:19V-256 MFR CAMPAIGN ID:M49 CAMPAIGN DESCRIPTION:2014-19 MDX Tailgate Inner Taillight Safety Recall RECALL DATE:03/28/2019 RECALL STATUS:17 Character VIN Required

During normal driving transmission will shift to Neutral, locks the system, and engine does not start when automatic idle stop had been engaged at stoplight or stop sign. Instead of restarting the engine, the feature causes the transmission and electrical system to lockup taking quite a bit of time to convince the car to restart.

Continental Crosscontact LX Sport 265/45R20 104H Tires have about 33,275 miles on them (rotated regularly) and one of the tires has a huge bump in the tread. The belt has separated from the sidewall. From what I've read, there are recalls on this tire, but not for this particular date that these tires were made. With it being on the front, it makes the steering wheel shake and I'm scared to drive it anywhere except to the tire store.

While making a very normal commute, my 2019 Acura MDX began running very roughly, slowing rather abruptly. The check engine light began flashing, and several warning messages were displayed on the message center of the vehicle display unit. The vehicle would not accelerate, and would not attain a reasonable speed while in traffic. With the hazard lights on, I was able to move to the side of the road, but it was very difficult as I was unable to exceed 15-20 mph. The vehicle was taken to the dealership for repair. The dealer investigated and found the timing belt had "jumped time" causing the engine management system to set multiple misfire codes, and was described as the cause of the failure. I am aware certain 2018-2019 Acura MDX models were recalled for timing belt issues, but this particular vehicle was determined to be outside of the group of vehicles involved in the current recall. My MDX had 52,600 miles at the time of the incident. It has not had any modifications or repairs to the engine prior to this incident. Acura recommends replacing the timing best at 100,000 miles.

I took the car in for a recall , 2 months ago and the car is still cutting off in traffic and at stop lights. This auto shut off , activates on its in and this dangerous.

UNKNOWN Over the course of a couple weeks, engine has intermittently stalled while driving, forcing me to turn off the car in the middle of the road. Progressively, other electronics have also intermittent failed including power steering and infotainment system. All dashboard warning lights are on and do not resolve by turning car on/off. Generally, car is driveable until the random intermittent stall, which is obviously dangerous. 2 weeks ago, car had gone through state inspection and 30k mile maintenance without issue. Service station checked battery and alternator and no issues.

Starting having an issue over the last few weeks where the car will shut off as it should with the idle start/stop enhanced but when I release the brake, the car goes into neutral and doesn’t start… have had this happen 4 times already and was finally rear ended today due to this fault.

The Car shut down in engine idle and would not restart. It was unresponsive and took 5 minutes for the start button to function. This occurred in the middle of a busy intersection. 2 weeks ago Acura performed an update to the software that was supposed to resolve the engine restart issue, but clearly it has not.

This vehicle comes with Idle engine feature. when the brake pedal is pressed, the engine turns off (supposedly to save gas). The car should proceed when the gas pedal is pressed. So at any time, in any location, after the car is stopped at a stop sign or red light, the car does not always turn back on. I just sit in the vehicle, unable to proceed. I then have to restart the car in order to drive forward again. This is extremely unsafe, as I could be stalled in an unsafe location. this vehicle had a recall due to this faulty issue, and the sensor was replaced by the Acura dealer, however the problem remains. I feel unsafe driving this vehicle. Apparently many Acura owners have the same problem. This problem could result in death. It is extremely unsafe to have a car stall.

My car was purchased with 12,000 miles and supposedly worn tires. Because of that, I went to the dealership to get new tires and an alignment since the car was always pulling to the right. My car has been at the dealership four times for the same problem, and they still haven't fixed it. My car continues to constantly pull to the right, and when I use the cruise control, it stays above the other cars to the right, causing it to suddenly pull to the left, deactivating the speed control and losing control. The dealership's recommendation is to stop using the speed control."

I pulled up to a stop light at a busy intersection/highway exit and, after depressing the brake, the vehicle abruptly turned off and shifted to neutral. The brake became very difficult to depress and the parking brake enabled on its own. The entire dashboard lit up and the car would not shift or respond to any input. The vehicle would not turn off, turn back on, or shift for approximately 15 minutes. After this, I tried to turn the car off and it finally did, I started it again and was able to pull off the roadway. We just recently (within the past 2 weeks) had a recall done to update the auto-stop system. This occurred 1x prior to the recall and now this has happened again. My young children were in the car both times and this put us all in danger.

Vehicle was stopped at a traffic light (transmission in Drive) and the automatic idle shutoff engaged, turning off the engine. When the traffic light turned green, the brake was released and we found that the transmission had shifted to neutral and would not shift back into Drive. We had to restart the car. Being stalled at a green light is a serious safety hazard as approaching vehicles would not anticipate my vehicle being stalled.

The contact owns a 2019 Acura MDX. The contact stated that upon locking the doors with the key fob, the vehicle would remain unlocked. Due to the failure, the contact believed that someone entered the vehicle and changed certain setting from the original setting. The contact was informed by the dealer that the setting change should not have shown on the multi-information display (MID) screen. The manufacturer was notified of the failure. The vehicle was not diagnosed or repaired for the failure. The failure mileage was approximately 40,400.

The contact owns a 2019 Acura MDX. The contact stated that on numerous occasions while driving approximately 55 MPH, the vehicle failed to respond as needed. The contact stated that the engine revved however, the vehicle went into LIMP Mode for 10 seconds and then operated normally. The vehicle was taken to the dealer however, the failure could not be duplicated. No warning lights were illuminated. The manufacturer was notified of the failure; however, the contact never received a reply. The failure mileage was approximately 55,000.

While in traffic the auto start sometimes fails to engage and the car stalls. Battery lights come on and the car goes into neutral on its own. I have to sit there and wait about 5 minutes in traffic before it restarts. Battery checked out fine. It has happened 3 times now. This is dangerous, and can/will cause a collision.

During Idle stop at red light car stops and goes into neutral and engine stalls. 2019 MDX won't move unless completely restart the car in the middle of busy intersection. High risk for accident and injury. There is few recall mention in Acura site for 2019 MDX, but when input vin number its claims no recall to this vehicle . Need urgent help.

When stopped at a light or in traffic the vehicle engages the auto idle feature. (turns off the engine to save gas). Upon releasing the brake, the car should re-start, instead the car does not start. The car jumps out of the drive gear into neutral on the transmission. The electrical system goes crazy and does not allow you to either turn off the car's electrical system or re-restart the car using the car's on/off button. This has happened to me at least 5-10 times over the last year. Each time the car becomes immobile in the middle of the road or highway for up to 2 minutes, until the electrical system resets and allows you to turn off all the power and re-start the car. It's a very scary and dangerous situation, when my vehicle is stranded in the middle of a highway or a road for up to 2 minutes, as traffic tries to avoid crashing into my vehicle. Searching online, I was able to see that this same condition has affected many MDX owners but Honda does not seem to have recall or fix for this issue.

In stop and go traffic on a highway, the car went to auto idle mode, then shifted to neutral by itself instead of restarting to drive. This was a safety issue in that I was on a major 4 lane highway with my kids and could've been hit from behind. The only thing I could do was completely turn off and restart the car. There were no warning lights. It has not been inspected by the dealer yet. There have been similar reports of this occurring: https://www.mdxers.org/threads/2019-mdx-auto-stop-feature-causes-car-to-stall-or-shift-to-neutral.175759/

The auto stop feature is enabled by default when the car is started. When stopped at a traffic light or in a traffic jam, the auto stop turns off the engine and is supposed to restart when the drivers foot is off the brake. The engine unexpectedly will not restart, and the car must be put in park, turned off, and restarted. This is dangerous in heavy traffic. The dealer replaced the battery as an attempted repair. The problem reoccurred. The dealer then updated the software, which also did not solve the problem. The dealer advised that Honda is aware of the problem and currently has no solution. I was advised to manually turn off the auto stop feature until a solution can be found.
