Acura headquarters USA 1919 torrence boulevard torrence, California 90501 mr. [xxx] [xxx] [xxx] email: [xxx] dear sir or madam, I am writing your company to the attention of whomever oversees the product development and design of the 2022 Acura Mdx and to warn them that certain system features and design flaws of this make and model vehicle will undoubtedly lead to the death of someone in the near future as was nearly the case with myself and spouse very recently. On Sunday [xxx], my spouse and I attended church services that morning. Fortunately, after services our Acura Mdx did start as usual, and we began our journey home. Upom arriving home, we backed our car into our garage and during that process thankfully I had the wits to unlock the passenger and driver side door mechanisms. Once we enteredthe garage and at thta point, our car went absolutely dead. Our car stayed dead for the next 5 1/2 hours. Had I not unlocked those doors, we would have been trapped inside for that duration of time, only to be found dead fron suffocation and asphysxiation from being in a car with all the windows rolled up, no power to the vehicle and no way to get out, while beingdeprived of oxygen. At that point, your manufactured vehicle became a death trap for us. We're the fortunate ones who lived through the experience and to be able to tell the story. Others may not be so lucky to tell theirs and there will be others. We wanted the manufacturer to understand the full implications of our letter and to stress in the strongest terms possible that this is a very serious matter that will eventually cost lives, as it nearly cost us ours. The vehicle in question is VIN# [xxx] and was last serviced at vandergriff Acura in arlington, texas on 6/13/2025 information redacted pursuant to the freedom of information act (foia), 5 u. S. C. 552(b)(6).

As I was driving under the freeway stopped preparing to make a u-turn my car put itself in neutral and I could not change gears. I had to turn the car on and off for it to get itself back into drive. Another time I was stopped at a light and it did the same thing. Some time went one and it happened again but this time I was reversing to park and again put itself into neural. This is a safety hazard as it happens at different times when I’m driving when other vehicles are around. I do the maintenance at the dealership and they never say anything about my complaints or the car needing to be updated. Please let me know what I need to do?.

I purchased the vehicle March of 2025. Since I have been to the dealership on multiple occasions. I was there less than a week after purchase because there was a noise coming from the front tire the dealership balanced the tire. The noise was still there so I returned and the next time they replaced the front wheel bearings. I still have issues with the steering wheel shaking so they replaced all 4 tires. The problem still persists but they don’t know why. The car feels unsafe to drive especially on the highway and in rain. I have had the recall for the brake pin assembly addressed and fixed. I also have issues with the audio shutting off or not responding the dealer did a hard reset and an update to the software that has not resolved the issue. The car would turn off at random times and struggle to turn back on when the idle shut off was activated. The dealer replaced the starter. I have had issues with the car randomly braking when there is nothing in front of me and other safety features either not working at all or working when not needed. Dealer advised it was a faulty battery and replaced it. I currently am still having shaking with loud noises especially at higher speed. The engine is very hesitant when accelerating and I struggle to merge onto the highway. It is also extremely jerky at lower gears and its most noticeable in stop go traffic. The brakes are squealing already and the mileage is low. I also sometimes need to press the brakes hard to even stop. The screen often goes black or will not connect to anything and I am unable to see directions or hear music. I feel extremely unsafe in this car and have anxiety every time I need to have anyone in the car with me.

Vehicle will suddenly shut the engine off and shift into park, even when the auto engine shut off is not active. Typically happens when stopped at a stop light. You will feel the engine shut off, and the car shift into park. It is very scary and unsafe. It has also caused the vehicle to shut off and shift into neutral while it was moving, and the vehicle gave a transmission warning. It sounds very similar to NHTSA recall 25v-031, however, my vehicle was not included in the recall as it is not a type s. I took it to the dealership and they said that Acura has opened an investigation due to the number of complaints, but there is no solution yet. I have not other option but to dry the vehicle, but I am worried that it is unsafe and not good for the vehicle to keep stalling the way it is.

Lane keep assist, adaptive cruise control, forward collision warning all stopped working and received error codes. Dealership stated camera was faulty and needed to be replaced at my cost. Continued issues with electrical systems where the car alarm will go off intermittently, and vehicle will not lock unless manually locking. Dealership stated Smart control unit needs to also be replaced at my cost. Part number for control unit #38320 was issued by Honda motor company service bulletin 21-055 for their Honda ridgeline. Acura dealer will not honor since part number does not specify Acura. Part issued in service bulletin is 38320-t6z-a11 (Honda ridgeline) part needed to be replaced by Acura is 38320-trx-a11. Other service bulletins related to original issues: 20-015, 19-005, 23-008, and 24-022 and safety recall report 23v-751. Dealership is still placing responsibility of repair of defective parts on car owner.

My vehicle intermittently fails to go into "drive" when pressing the gear shift button. Additionally, various warning messages appear at random, including: lane keeping assist problem, & road departure mitigation system problem. I have brought my vehicle to dch montclair Acura#709, located at 100 bloomfield Ave, verona, NJ 07044, on January 10, 2025, February 18, 2025, and March 13, 2025. Despite these visits and an inspection conducted by my extended warranty provider, the problem continues. On [xxx], while my daughter was a passenger, the vehicle once again failed to shift into drive when pressing the "d" button. This incident, like others before it, occurred without warning and reinforces my growing concern about the safety and reliability of the vehicle. I am now afraid to drive the car, unsure when it might fail again. I respectfully request that Acura take immediate and decisive action to investigate and resolve this issue. If a reliable repair cannot be made, I would like to discuss alternative remedies such as vehicle replacement of buyback under applicable warranties and safety protections.

Start n stop button not working right shuts off and hard to start.

The engine light came on more than 12 times in the past 3 months. I tried to have the dealer check, but they found nothing. Then the light started to of on and off every time I drive in the rain.

My 2019 Acura Mdx with 100k miles stalled on the road with several alerts on the dashboard and went into parking mode with no further movement. Had several alerts stating transmission failure, blind spot monitoring failure, auto break system failure and vehicle stalled on the road. Had similar issues previously where the steering jammed and vehicle was stalled on the signal, took it to Acura dealer and they had to fix some circuit / reset the circuit board. Was ok for few months and last week the car stalled with parking sign on. Towed the car to the dealer service center, they diagnosed and identified there is a failure with transmission. They quoted around 10000 dollars for replace new and 7000 for used transmission. This is huge money, hence called Acura customer care for any review/support but they claimed this issue is not in their current recalls or claims, so cannot support. Had to pay out of the pocket. Per google there seemed to be a lawsuit with transmission failures with Acura 2019 Mdx vehicle. Acura customer relations is asking to get into the law suit group and Acura as such cannot help the customers with these problems. Had Lexus for several years with no issues and very upset/annoyed with these type of repairs within 100k / 5year old.

There is an active recall on the brake calipers and fuel pump for Acura Mdx 2017, and hondas. My Acura Mdx 2017 has the same issues with a code of p07e4, which is the brake calipers. When looking up the recall of my car, there is no recall on it when inserting the VIN. My car is an Acura Mdx 2017; I do not understand why it is not included in the recall when it should.

Electric parking brake problem and emission system problem lights came on spontaneously.

My vehicle has a battery issue, we replaced the battery twice in two years still the issue might happened again and again. Once the battery start draining energy, everything start blinking and car stops all of a sudden in the middle of the road because of brake assistance problem. All the system errors come up. It is very scary to drive the vehicle with my kids inside. All system in car works with battery. Service center told me that this kind of cars needs bigger battery and company only put small batteries in the car. Company don’t put warranty on battery if it is replaced under car warranty. My car is only 33 months old and I have to change battery twice, it might happen again. Please help me to resolve the problem. It looks like factory problem that company do not make sufficient batteries to satisfy the vehicle needs. I have attached the pictures of safety lights.

I reported these issues to Acura corporate and to jackson Acura, dealership I purchased the vehicle from in February 2024. Beginning in July 2024 the vehicle would stall, DE-accelerate then the automatic brake would engage, and the vehicle would go into "n" mode, neutral and lock up. I was able to press the gas pedal a few times, and the vehicle would come back online and drive. This issue happens about every 100 miles driven. On [xxx] the vehicle suddenly DE-accelerated, went into auto brake mode and then shifted into neutral. On this date the vehicle locked up suddenly to an abrupt stop, we were almost impacted in the rear with two other vehicles having to take evasive action to avoid hitting us. My wife and I were lucky not to injured by the sudden brake, or transmission lock up. There were no other issues with the vehicle until this date, other than the stall issue. It seems the system had a sudden catastrophic failure. The car has been maintained with oil changes, new battery and transmission service. The car was shutdown then restarted. All the lights on the dash were on and the vehicle was unable to shift to any gear. The vehicle had to be towed to my home address. I was advised to have the vehicle towed to a dealer for diagnostics at my expense. It is currently at nalley Acura, marietta, GA being diagnosed for the issues. The vehicle has 74,000 miles currently. It was purchased with 57,700 miles from jacson Acura as a certified Acura used vehicle. The Acura dealer and Acura corporate both stated my VIN # was not included in the recalls. It should be included in the recalls as it has the same issues as other Acura models. Information redacted pursuant to the freedom of information act (foia), 5 u. S. C. 552(b)(6).

There is a recall on my 2020 Acura Mdx and I have been going to the local Acura dealer to get the part for the last 6 months and every time I go they tell me they are still waiting for the part. Periodically, the vehicle lurches while I am driving causing a major back and forth tugging and jerking. This is very unsafe. I am demanding that Acura prioritizes my need to get this fixed. I do not know if the jerking of the vehicle is due to the recall, but regardless, Acura needs to do the right thing and send the part to the Acura dealership so I can get this fixed. No Acura dealer in my area says they have the part. I am on a "waiting list. " my car last did this jerking motion on 12.

The vehicle stalled and was unable to start again, called aaa , they jump started but when I went to dealership they said it wasn't the battery. The car electrical electric system was flashing. The breaks won't release. This is not the first time. My car is currently in Acura service for 5 days and they can't figure out what the problem is. My friends car also has had similar issues. I have a video of the flashing indicators. The car has only 33k miles.

See attached document for complaint.

I was lightly stepped on the gas coming off a complete stop with no cars in front of me. The automatic breaking came on hard and a sensor flashed to brake as if I was going to hit someone but there was nobody in front of me. The sensor alert system was turned off 15min prior as I had gone through a car wash. This is the first time this has happened but unknown why. Had there been a car behind me, I may have been hit.

My vehicle stalled and the engine cut while I was waiting at a stop light. The engine auto shut-off feature was active at the time of the incident. While sitting a the red light the auto engine feature shut the engine down, which is normal to reserve the use of fuel while at a stop light. When I took my foot off the brake, the vehicle should have restarted. But instead, the vehicle went into n (neutral) and the engine did not restart. I was sitting in the middle of traffic with cars behind me, so I put the emergency signal on, I then put it in p (park) and started the vehicle. This is the second time this has happened. The first time I thought I touched the neutral button by mistake. There were no injuries, but I'm concerned that this could cause a crash in the future,.

I am [xxx] and I have owned Honda/Acura since I was 16 yrs old. My last vehicle was a Honda odyssey minivan with 423k when I donated it, running well to a family that fostered kids! I bought a new 2016 Acura Mdx and now it is 8 years old and has 180k on it. I get the oil changed and other normal service maintenance done only at Honda or Acura dealerships. I have never had a car accident and I take care of the maintenance early. All of a sudden, on Friday, [xxx], I had just started driving ( ~20 minutes in the car) and every light started flashing and the car sounded funny and it was hard to drive. I immediately got off the highway and found a repair place (red's auto repair) right off the exit. They had me shut off the car. Then they checked the oil, which was showing 70%, and I had just had it changed less than 1000 miles earlier, and it had plenty of oil. They told me I could not drive the car! they said "something is wrong with the engine". Currently, lafontaine Acura has my car. I have a loaner from them. They said it "spun a bearing" in the engine. Apparently there is a recall for this same problem for my year, make and model, but "currently" my VIN number is not included? and, it is the exact same problem bearing from the recall! this is crazy! my car has been well taken care of and I would expect it to get at least 350k miles at least before any issues. If the same problem was recalled for other cars, why not mine? it is un-drivable now. I think that Honda has changed their manufacturing because in 43 years of driving hondas they always are reliable and work well for years and years. My 5 adult kids drive hondas as well! never a problem. I think I got a vehicle with a defect that should not be, especially when the car has always been maintained so well, with the service records to show that. Please help get this included in the recall for safety! what is my next step to ensure that my car is included? thank you very much information redacted pursuant to the freedom of information act.

Vehicle always smells hot or as if something electric is burning in the engine compartment. Have always had scheduled maintenance and have taken it in on time for all oil changes and maintenance to be performed. Have asked for this to be checked at that time and when the smell has become over powering. Engine lights have popped up and then all lights have shut off two separate times previously to the point where I had to turn off the vehicle. I have taken it to two dealerships and another mechanic to look for the cause. They are not able to determine the cause but recommend I contact Acura as this sounds like a warranty issue.

I came to a stop at a stop sign. The start/stop feature activated and the engine shut off. When I lifted my foot off the brake, the engine did not restart (as it's supposed to), and then vehicle automatically shifted itself into neutral (without any of my doing). I put the emergency flashers on to alert other motorists, hoping to avoid a rear-end collision as I was stopped in the middle of an intersection in rush hour traffic. At this time, the battery light illuminated. The engine light illluminated as well. I had to forcefully and unusually push the brakew pedal towards the floor as the vehicle was drifting backwards. At this time, the vehicle would not shift into park. Then "park" illuminated, so I attempted to reapply the brake hoping that when I let up from the brake the car would start again (like the usual procedure). The vehicle then shifted into park, but the engine had not restarted. I pressed the on/off red button to follow normal procedures for turning the vehicle off. With my foot remaining on the brake, I pressed the off/on red button to start the engine as usual and the engine finally restarted. Afraid for the safety for myself and other motorists, I put the vehicle into drive and I pushed the button to stop the stop/start system from engaging. No codes generated during this. This is a safety issue for several reasons. First, I was stuck in the middle of a busy intersection where a large volume of cars travel through each day. It was rush hour, so the roads couldn't be more filled. Someone coming around the corner who might not have been prepared to stop could have hit me. Likewise, I could have been hit while in the intersection. Secondly, once the vehicle failed to turn back on, the washington grove (montgomery county fire and rescue services - mcfrs) was responding to a vehicular file nearby on I-270 and had I not have been able to move in time, some of their vehicles likely wouldn't have made it through because my vehicle was blocking the lane.

Electrical, brake and car acceleration problems.

We experienced multiple/many warning lights all at the same time. Systems not working. Repeated every time. The Acura dealer diagnosed the problem to the dtc u3000-49 multipurpose camera internal electronic failure. Replaced the unit and they performed a couple of calibrations. Thank you, [xxx] information redacted pursuant to the freedom of information act (foia), 5 u. S. C. 552(b)(6).

When the vehicle is idle, for instance at a light, it will shut down. It idles a little, goes into neutral and shuts completely down having to be restarted. I always turn off the automatic start on the vehicle after I start it, so it is not that. It has also done it while driving. It is very unsafe to be driving in traffic and have your vehicle shut down with no warning. Please advise on what actions should be taken to correct this issue.

Upon engine start noticed vibration buzz noise and steering wheel locked, very difficult to steer. Turned off the ignition and waited 20 min, steering wheel was back to normal. Upon driving in the road for approximately 5-10 min, the wheel locked up with notification alert of "electrical power steering failure" it was very difficult to maneuver the steering wheel and manage to pull into a parking lot. Turned the ignition off and waited again another 5min and upon restart, wheel was back to normal. As we were on our way home, the same alert came with steering wheel locked and difficult to turn. We managed to get home with difficulty turning. Car was towed to Acura plesanton and was reported no recalls for this issue.

Twice so far my car just turned itself off while stopped in traffic at a stoplight. It would not turn on immediately. Traffic built behind me, steering was locked, brakes not working. After sitting a minute or so it would start again and then the steering would then work, gas accelerator, brakes would all then start to work again. It was scary and unsafe. This needs a recall!!!.

Driving when all electronic lights flashed. Rakes steering driver assist lift and towing. Said see dealer reset after I waited at gas station for 30 min power steering worked but was hard to control car.

For the last 50k miles we've taken our Acura Mdx to the dealership for regular oil changes. Almost every visit results in a bad battery. We've had the dealership replace a side mirror due to the electrical and several batteries as well. They've kept it for several days diagnosing issues but haven't to this day found out what's wrong with it. Now my back taillight stopped working, we bought another one and replaced it for it to work for a couple months and stop working again. Now we've taken it to another place for diagnosing, they have said the inter taillight assembly and wiring needs replaced. Seems like this has been the issue the entire 6 yrs we've been complaining. The dealership says they took care of the problem already, clearly this is a safety issue when driving at night especially. Having a taillight that works off and on is not my idea of safe or "fixed" according to the dealership.

While waiting to turn left from a busy street onto a highway, the engine seized. The car was unable to be moved from it's location in the center of the busy street with cars approaching quickly from behind and weaving around my stopped vehicle. I had the vehicle towed to metro Acura in montclair, CA and they confirmed that the connecting rod bearing had failed causing the engine to seize. They also confirmed that the vehicle is not part of the existing recall. The engine produced some rough noise prior to failing but otherwise did not provide any warning lamps or other messages.

1. ) I have had repeated, on-going issues with the fuel propulsion system since the day I bought the car. When I step on the accelerator it randomly (lately more constant than random) does not respond, then it will shoot me out into traffic. For example when I am entering the highway from an onramp, I see my opportunity to merge into traffic and I step on the gas - nothing - no response, then it suddenly accelerates and shoots me into oncoming traffic. This is so bad that I am afraid to drive the vehicle. It is deadly. I have reported the issue every time I have had the car serviced (always dealer serviced, from same dealer where I bought it. ) 2. ) the vehicle will randomly decide that I am going to hit a car in another lane, and will forcefully apply the brakes (when there is no issue, no danger, no possible way I am going to even be close to hitting another car) causing the cars behind me to come extremely close to rear-ending me! or the car will decide I am going off the road when I am taking a soft curve, and it will sound a warning and try to turn the wheel. 3. ) the display panel will go black for no reason. I then cannot use the navigation screen. It will randomly return after a few hours or after a day or two. 4. ) the camera/display will get stuck on the reverse camera causing a visual disconnect as I drive forward, but can only see what is in reverse. (like seasickness). No idea what causes it or how to fix it. Eventually it corrects itself after a few hours/day+. 5. ) car will occasionally make a strange squealing noise after it has been turned off - no idea what that is, or what causes it. As a salesperson who spends many, many hours in her car, this vehicle has become a constant danger to both my livelihood and my life. I am afraid to drive it and I will not let family members drive it as I am afraid for their lives due to the issues stated above.

I was driving down the highway today at 70 mph and all the lights illuminated on my Mdx. It began to struggle to keep speed and eventually shut down once I was on the service road. I was extremely scared and nervous that I was going to be involved in an accident or the car was going to blow up as it started bouncing up and down while I was still on the highway.
