  Intermitted Flashing Dash Lights, Headlights, and Car Alarms. Steering wheel moving up and down. Looks like the same issue as Service Bulleting 21-055.

  I had purchased this vehicle and was not aware there was a stop sale on this vehicle model. I took the 2020 MDX to the dealer to get the recall service done, the connecting rod bearing and fuel pump issues. They were done back in March of 2024, j had taken the vehicle back to the dealer over 5 times for issues with stalling and trouble turning back on as well as engine noise, ticking and stalling. The dealer “cannot replicate” the noise all of sudden, but was initially able to hear the noise and stated “ it’s probably fine, but bring it in if it gets worse” this issue happened after the recall service was performed and the vehicle has never been correct since, I believe there is engine damage caused by the needed recall service.

  Twice at a stop light the car went into neutral by itself which then required me to go put in park then drive. One time a police officer was nearby and pulled me over after, asking if everything was ok since I was stopped at the light for a prolonged period of time. I took it to the dealership and they said it was the battery and replaced under warranty. Battery should not go when car has less than 30k miles. I checked forums and many people have experienced this issue. There are too many other complaints on line not to bring this to your attention. It has happened already. It is very nerve racking to be at a stop, hit the gas and go nowhere when traffic is quickly approaching from behind. This will eventually lead to someone getting rear ended.

  The contact owns a 2020 Acura MDX. The contact stated that while driving at slower speeds, the vehicle stalled and shifted into neutral. After shifting to the park, the vehicle was restarted and operated normally. The contact stated that the failure had occurred on numerous occasions while accelerating from a stop or while decelerating to a stop. The vehicle was taken to the local dealer on multiple occasions and software updates had been performed, the battery and starter were replaced, but the failure persisted. The manufacturer was notified of the failure. The approximate failure mileage was 25,000.

  The rear seats for my 2020 MDX are making a loud squeaky noise. The car has all of 47,000 miles and this should not be happening. American Honda wants $4,467 to replace the rear seat that is in a newer car from 2020. I’ve already had to spend over $2,000 last year to replace the drivers seat motor. I’d like to know if this problem is prevalent in the 2020 MDX with other owners? I’d appreciate your insight. Thank you.

  We were traveling far from home on I-44 in Missouri when our 2020 Acura MDX experienced a total engine failure. An engine rod broke and pierced the oil pan causing a sudden loss of engine power. I believe this is related to the NHTSA Investigation #RQ24013, even though the Acura dealership had performed the recall service for this issue a couple months earlier. I suspect the recall service was either performed incorrectly or that a part was not tightened properly, ultimately leading to the engine failure.

  The contact owns a 2020 Acura MDX. The contact stated that upon coming to a complete stop, the vehicle suddenly stalled. After which, the contact became aware that the vehicle briefly failed to detect that the key was present, preventing the vehicle from restarting. After a while, the vehicle was able to detect that the key was present, and the vehicle started. The vehicle returned to normal functionality, but the failure became a regular occurrence. No warning lights were illuminated. The vehicle was taken to the dealer, who was unable to duplicate the failure. The manufacturer was not notified of the failure. The failure mileage was 10,000.

• 12/10/2025· FORWARD COLLISION AVOIDANCE,LANE DEPARTURE

  I drove my car in the morning and parked it in the lot for about an hour. After I came back and started my car, the following multiple safety systems displayed on my dashboard at the same time: - Lane Keeping Assist Problem - Collision Mitigation System Problem - Road Departure Mitigation System Problem - Auto High Beam Problem - Adaptive Cruise Control Problem When I took it to the dealership on the same day to diagnose this, they came back and said it was an internal failure with the camera and quoted me around $2200 to replace and recalibrate the camera. These lights just came on out of nowhere, I had no repairs or modifications with my windshield and there were no accidents of any sort. This appears to be a widespread problem among 2020 Acura MDX vehicles with similar camera modules. A malfunctioning front camera can prevent the vehicle from automatically braking or maintaining lanes, hence increasing the risk of collision. I am requesting that NHTSA investigate the front multi-purpose camera system on the 2020 Acura MDX for potential defect and safety hazard.

  There is a clear engine knock. I have a recording of it both on video and audio, my engine performance and gas mileage has gotten worse. I picked up on the sound about 6 weeks ago and called (Mueller Acura), said I would have it checked at the next oil change. The dealer (Mueller Acura of Merrillville) has had my Acura MDX, for two days two weeks ago and for the last 7 days, currently. The didn’t tear down the engine completely. But they told me they had their master mechanic and Honda’s (from another shop Team Honda) Master mechanic came down and used a camera and I have a bad tensioner, bad rockers, and a bad cam shaft. I’ve been speaking with an outside mechanic who is a Honda certified Master mechanic who now runs an independent shop. Acura, says I have a bad camshaft, bad rockers, and bad tensioner. They said I need all of those replaced as well as the $3000 100K service. They are deeply discounting what they quoted me because I’ve documented well and made so many trips out there to physically show them the engine knock (right now they want $3606 to fix and then they will listen again). They finally heard it at the back of the engine. I’m in a rental and it’s costing me daily. The independent shop says the correct answer is you have a bad engine and they need to check the crank shaft, the head, and the rod bearings, in addition. He said if I changed the oil myself I would probably see metal particles in the oil and if I fix it I’m wasting my money as the entire engine is in need of replacement. It only has 86K miles on it and should not have these issues. I don’t think I should have to pay, and I need my vehicle back. I’m now without a vehicle and they are demanding I give them an answer by Monday at 7am on whether or not I’m fixing it. They won’t put anything in writing as they want to keep it kept quiet until I make a decision. The service manager is now trying to talk me into trading but not at their dealership. I feel like May need to contact an attorney.

  Was at stoplight with idle stop on and when light turned green car wouldn’t engage. Saw it had shifted to neutral and needed to turn the car off, restart before I could drive away. Could have been hit from behind especially since it was dark out

• 12/04/2023· ELECTRICAL SYSTEM

  I was on a bridge heading into a tunnel stopped due to traffic and the car shut off completely. The screen said to put the car in park and restart it. I tried several times and after a few attempts it started back up. This is the third time this happened. I had a recall when I purchased it and had the recall addressed for the same issue. Now I am back at Acura again. And being told I may have to pay for diagnostics. The car is still under warranty.

  The Auto Start-Stop Technology is malfunctioning. I bought my 2020 Acura MDX in 2022 and with the first 2 weeks of having it, it turned completely off while in a drive through line. It only does this when the Auto start- stop is on. I took it back to the dealership and of course they found nothing wrong. This happens frequently and sometimes the car doesn’t want to start back up. Sounds like I am not the only one with the same issue.

• 11/30/2023· ELECTRICAL SYSTEM

  While coming to a stop the engine start stop engaged causing the engine to turn off completely and would not restart when the throttle was pressed . The transmission shifted into neutral and the push button start would not fire the engine. Car would not go back to park. After locking and unlocking the door 30 seconds later it reset and the engine refired. This occurred with traffic flowing behind me and caused the car to be placed in neutral and the driver having no control over the vehicle. If this had occurred in an intersection while turning, the driver and occupants of the vehicle could be in significant danger of an accident. I took the car to the Acura dealer the next day and was told they had several complaints of this kind but would need to duplicate the issue on my car to assist me. If they could not duplicate the issue then the could not help me. At this time, it has not been inspected by the manufacturer. There were several warning lamps that came on when the car turned off.

• 11/29/2024· ENGINE

  My car is producing a loud noise from the engine bay, which closely resembles the sound of a failing crankshaft. I have taken the vehicle to the dealership several times, but they were unable to determine the source of the noise. I consulted with an experienced mechanic who advised me that the engine is likely to fail soon if the issue is not addressed. He recommended inspecting the internal components of the engine, specifically the crankshaft, for potential faults. I am not sure if the official dealership can check my engine for a faulty crankshaft.

• 11/28/2025· FORWARD COLLISION AVOIDANCE,LANE DEPARTURE

  While driving my 2020 Acura MDX with 29,647 miles, all AcuraWatch safety systems suddenly failed at once, including Collision Mitigation Braking System (CMBS), Lane Keeping Assist, Road Departure Mitigation, Adaptive Cruise Control, and Automatic High Beams. Multiple warning messages appeared simultaneously. This disabled forward collision warning, automatic emergency braking, and lane departure/lane keeping functions, creating a serious safety risk. The dealer inspected the vehicle and confirmed an internal failure of the multipurpose front camera/radar unit, and recommended replacement of the entire assembly. The repair estimate is 2,200. The dealer stated the component has failed and cannot be repaired. This issue is widely reported by many Acura owners of similar model years, and appears to be a recurring defect. The failure occurred without any impact, damage, or modification. The vehicle is available for inspection. The symptoms began suddenly and all warnings appeared at the same time. Because this failure disables critical collision-avoidance and lane-keeping systems, it presents a significant risk to the driver and others on the road. I believe this should be investigated as a safety defect.

• 11/28/2023· ELECTRICAL SYSTEM,SERVICE BRAKES,FORWARD COLLISION AVOIDANCE

  Auto braking system engaged abruptly, without necessity. This occurred twice (December 2022 and November 2023) almost causing collisions on both occasions. The dealer could not reproduce the problem when it was brought in in December 2022 and said this could occur if the sensors are dirty and to ensure they are always clean. I have since done so, and the same thing happened again. There were no warning signs for this error prior to it occuring.

  My 2020 model Acura MDX is experiencing unexpected engine shutdowns while braking during motion. The issue has been reported multiple times to the vehicle manufacturer and their authorized dealers; however, their responses have been consistently unhelpful and have not resolved the problem. I currently have an open complaint with American Honda Motor Co., Inc. since December 2023 Case Number: 14329512 Additionally, I have found numerous reports online from other owners of the same model experiencing the same issue, as documented here: 2020 Acura MDX Engine Complaints – CarComplaints.com This recurring malfunction presents a serious safety risk, especially in moderate traffic conditions, where sudden engine failure during braking could lead to collisions or injuries.

  I started to here a very light knocking noise on cold starts. I made an appointment with my dealership to check it out. The earliest appoint they had open was a bout a week out. A few days later I was driving on the highway and the knocking noise suddenly became very loud and all the dashboard lights came on. The vehicle lost power and I barely coasted off the highway before the MDX came to a complete stop. I called AAA and had the car towed to the dealer. The next day they called me and told me it had been a connecting rod bearing failure and needed an entire new engine for $25,000.00. I was in total shock. I googled what happened to me online and found this is happening to many acuras and hondas. The dealer said there is absolutely no warranty and they cant do anything even though there are articles online and from NHTSA saying this is a common problem and under investigation. I was forced to replace the engine in my car because I still have a loan on it and dont know what else to do. The engine basically blew up on the highway in heavy traffic and was extremely dangerous and now acura wants nothing to do with the repairs. I think this situation deserves investigation.

• 11/18/2025· ENGINE

  I was driving on the interstate when suddenly the check engine light began to flash and the car lost power. I was traveling at 70 mph and the sudden loss of power caused the vehicles behind me to move into the other lane to prevent rear ending me. While there was no accident, there could have been if the other drivers were not reactive. There was no advanced warning. This could have been deadly for me and my family. I was several miles from home and needed to have the vehicle towed to a mechanic who stated it sounded like a rod bearing and suggested we take it to an Acura dealer. We are yet to have a resolution.

  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!!!

The contact restarted the vehicle several times to shift back into drive. The contact also noticed that the steering wheel had seized, making the steering wheel difficult to turn. The vehicle was taken to the dealer but was not diagnosed or repaired. The manufacturer was not mad aware of the failure. The approximate failure mileage was 26,000.

• 11/12/2024· SUSPENSION

  I brought my 2020 Acura MDX with 61,086 miles on it for a routine service and was informed that the front suspension control arms were failing and needed to be replaced within weeks otherwise it could break causing a safety issue while driving. I have never had a car including prior MDX's that required this to be replaced and when I asked about it, I was told by the dealer and other dealers that I spoke to that is was unusal for this to happen with this many miles but it can. I feel that this is a manufacturer flaw and could be an issue in other MDX's. Again, if I did not go in for routine service at that time, it could have resulted in a safety incident within weeks according to them without notice and there was no mention of this with my prior routine service back in June 2024.

• 11/12/2022· UNKNOWN OR OTHER

  When the brake is suppressed at a Stop sign or stop light, the vehicle has an Auto Idle stop feature which shuts off the engine completely to preserve fuel. The vehicle is supposed to restart once the brake is released. In my case, there have been multiple times when the brake is released but fails to restart and go. I have encountered the issue in the following scenarios: 1. Getting off the freeway, if there is a line getting off the freeway, then the vehicle will potentially shut off and fail to restart. This is a safety hazard as the driver behind me or others behind at a distance can potentially hit the vehicle. 2. At a Stoplight, especially when making a left turn, the vehicle will shut off and fail to restart. It takes more than 8 secs to restart/reengage by restarting manually. If there are any vehicles attempting to go behind me or at a distance, then they can potentially hit my vehicle. This is a huge risk to my family and I, to assist in our safety, we end up having to turn on our hazard lights. This is unacceptable especially since this is a 2020 vehicle with under 45k miles. I have attempted to reach out to the Acura service team, Customer relations team and even called the Warranty department. However, they were not taking ownership on the issue and responded as it has not been reported before. Based on forums, the issue is being encountered by other owners as well. Hopefully, this can be sorted in the near future for safety of my family.

• 11/08/2024· FORWARD COLLISION AVOIDANCE,LANE DEPARTURE

  While at a stoplight, my car notified me of many sensors having "problems" From my understanding, it relates to the front camera located on the windshield. I am unable to use these additional safety features since the problem arose earlier this week. Had this gone out while I was driving, my family and I could have been fatally affected. My cursory research online shows this is a recurring problem that customers need to address independently. All expenses are paid from their own pockets. There were no warnings prior to the system's failure. I have not taken my car in yet for this to be addressed. I am frustrated that this is a known issue with no proactive solution by a brand I had trusted.

  Idle stop feature causes vehicle to auto shift to neutral at stop. There are many forums noting this issue. It happened a year ago several times, they replaced the battery and it is happening again. You are sitting at a light or stop sign, go to hit the gas, and the car is in neutral. You need to turn the car off and start again. This is a serious risk of getting rear ended with this issue. One time when it happened last year a cop pulled me over to see if everything was all right. The car should not be shifting to neutral at a stop.

• 11/03/2025· STEERING

  The power steering failed while driving, and multiple warning lights came on. This happened in the middle of a busy city street and came very close to causing an accident. When the car was restarted the power steering came back on line but failed again the next day. My wife and I decided it was unsafe to drive and had it towed to the dealer. The dealer told us that the "Wire Harness" failed and the Clockspring/Reel assembly had to be replaced. The total cost was $3,888.91. There were no warning lamps, messages or symptoms prior to the failure. This is definitely a safety issue. The dealer had no explanation of why a component like this should have failed. I contacted Honda and was told that there is no recall on this part and i should make a report to the NHTSA. This was a scary and distressing event. Please look into it and get Honda/Acura to issue a recall.

  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 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.

  2020 Acura MDX, bought this in February of 2021. Issue with the auto-idle completely turning off the engine, when you pull up to a red light or stop sign and the engine goes into Auto-idle, then go into neutral, sometimes showing the battery sign. The car is completely disabled, have to shut off the engine and restart. This happened about 3 times, the last time was with my 2 young children in the car and people honking at me!!!!! Brought it into Acura, when said it was battery issure and replaced the battery in Sept. 2022. August 2023, brought it in for 2 recalls, once was for the idle engine, they service person said the issue was fixed. October 2023, by car did not restart from auto-idle (AGAIN TWICE in less than a week), brought it in again, they said they couldn't find anything wrong with it!

  Our 2020 MDX we lease has lost electrical 3x since Sep 1. Once while sitting at a stoplight. Twice while turning at intersection. Each time, there was a complete power loss. When the car was moving, it quickly slowed to a stop in the road. In each case, it took a few minutes to get the car restarted due to being startled at what happened. I checked the battery cables, and they are tight. The radio settings were not lost, so I do not think it was a battery connection failure. We are not sure what to do with this as, while there are a lot of similar reports for acuras, there is no consistent diagnosis.

  There was an active recall on this car from Acura for the auto start system malfunctioning. When the car auto stops at a signal or stop sign it does not turn back on sometimes. We took the car to Acura 3 times for the same issue and they keep saying that it is fixed but the recall was never fixed. This is highly dangerous in traffic situations when the car does not turn back on when you take your foot off the brake.

Step on gas pedal and car will not go. Tried putting into Drive but will not shift into Drive. Lots of vehicle behind me. It was very scary and dangerous, I could have been rear ended. I had to turn the engine off and restarted again then I was able to put it Drive and go. This issue happened twice, once at a stop sign about a month earlier.

  Issue with Auto Idle Stop. I have had multiple instances of the auto idle stop kicking in and shutting the car off while I am at a stoplight. This has resulted in VERY close calls with me getting rear ended. I have taken the vehicle in to be inspected at an Acura dealership only to be told that they cannot replicate the issue. When this issue occurs, it takes about a minute to get the car working again. The dashboard lights up with a lot of different flashing lights. There was no warning prior to this issue occurring. You cannot permanently shut off the auto idle stop and I should not be expected to remember to do it every time I get into the vehicle. I am afraid that one day this will cause a bad car accident that will lead to myself or my family getting severely injured/killed as other drivers are not aware that the car won't be going. The most recent incident occurred last weekend.

  On multiple occasions, after coming to a complete stop, the engine shut off as designed but then failed to automatically restart when I released the brake pedal or pressed the accelerator. This left the vehicle completely disabled in traffic until I manually restarted it by shifting into Park and pressing the ignition button. This failure is unpredictable, occurs without warning, and poses a significant risk of collision, particularly when stopped at busy intersections or in heavy traffic. I contacted my Acura dealer, who confirmed that this issue is a known concern on 2016–2020 MDX models and that Acura has issued Technical Service Bulletins (such as 23-001 and 23-002) and a warranty extension. However, even after updates, the problem continues to occur, and there is no permanent remedy at this time.

  The engine idle stop function is unreliable and often fails to restart the engine when the brake pedal is released. The vehicle will, suddenly and without notice, become inoperable and undrivable wherever it rests, whether at a red light or stop sign, in the middle of an intersection while making a left-hand turn, or on an entrance ramp to a highway, causing a dangerous situation for myself and other drivers. It takes several minutes to restart the engine and sometimes must be jump-started. The issue has been reported to my local dealership, and they said it is not covered.

  Auto idle cuts off idling at stop light but when reengaged stalls the car completely. Must totally restart car before continuing causing back up in intersection and almost being hit. Happened several times, when I forget to turn auto idle off. New battery did not help
