| May 2026 | SUSPENSION | Clunking or Looseness in the Outer Tie Rod. The issue is related to TSB-B23-019 Bulletin. The exact same issue is occurring that has happened with years 2022-2023. I have had at the dealership to fix the issue and they never mentioned the outer tie rod cotter pin or castle nut loosening. | Crash: No Fire: No | Unknown |
| May 2026 | ENGINE,FUEL/PROPULSION SYSTEM | I am reporting a recurring safety issue following the Acura rod bearing recall repair on my 2019 Acura MDX SH-AWD. The original recall resulted in catastrophic engine failure and Acura replaced the long block assembly. Since that repair, the vehicle has repeatedly failed and returned to the dealership multiple times for the same issue pattern. Symptoms include: * “Emissions System Problem” warning * SH-AWD, brake, and traction control warnings * strong raw gasoline odor * vehicle becoming undriveable/no-start Timeline: * Recall repair completed with long block replacement * Vehicle failed again the next day * Dealer repaired vehicle * Vehicle failed again about one month later * Dealer repaired vehicle again * Vehicle failed a third time about one week later during normal commuting The recurring failures are accompanied by a strong gasoline smell, creating concern about fire risk and vehicle safety. I regularly transport children in this vehicle and no longer have confidence in the safety or reliability of the recall repair. The dealership has continued repairing the vehicle and providing loaners, indicating the issue is related to the original recall repair, but the underlying problem has still not been resolved despite multiple repair attempts. I am submitting this report because the recall repair has not resulted in safe and reliable vehicle operation. | Crash: No Fire: No | Unknown |
| Apr 2026 | POWER TRAIN | The contact owns a 2019 Acura MDX. The contact stated while driving at an undisclosed speed and depressing the accelerator pedal, the vehicle failed to accelerate as intended and to exceed 5 MPH. The vehicle was driven to the shoulder of the roadway. The contact stated that several unknown warning lights were illuminated. The vehicle was towed to the dealer, where it was diagnosed with transmission failure. The contact was informed that the transmission needed to be replaced. The contact did not agree with the diagnosis. The contact stated that the failure was a known failure with the vehicle. The vehicle was not repaired. The manufacturer was made aware of the failure. The failure mileage was approximately 72,692. | Crash: No Fire: No Towed | 72,692 |
| Apr 2026 | SEATS | The drivers seat is lose and can be felt and heard making noise when driving, even at low speeds. It shifts back and forth upon acceleration and deceleration. Ive had a mechanic look at it and determine it is in fact shifting around while driving, which is extremely unsafe. Upon further research found that many othet Acura/Honda users have had the same issue especially in the MDX model mentioned here. Its even been reported by dealers in brand new, still in the showroom MDX. It is clearly not a wear and tear issue and needs a recall to be addressed. | Crash: No Fire: No | Unknown |
| Apr 2026 | ELECTRICAL SYSTEM,ENGINE | My car has stalled while driving on the highway multiple times now. The first time it happened, it lost power, stopped accelerating, and cycled through multiple warning lights, causing a significant safety risk. I pulled over and it restarted within minutes. I took it to a repair shop and they could not find a problem with it, even with the codes provided. Nothing pointed to a solution. It happened two other times while I was driving my child on a highway where it lost acceleration and then kicked back in. Again, this post, a significant safety risk as always in a fast lane on a highway with my child cars behind me had to hit their brakes to avoid me after this incident. Other times it doesn’t lose power, yet it cycles through warning lights randomly. I took it to the dealer instead of a local shop. They texted me about items that should be fixed per an inspection, including struts and a battery replacement. Complete with a large bill just for diagnostics. Yet, nothing was found having to do with the main problem at hand. Losing power while driving. . My battery is less than six months old. I had it tested and it is fine. My vin is not listed in the recall, but, all of the symptoms match the other recalls of the same year make and model. | Crash: No Fire: No | Unknown |
| Mar 2026 | AIR BAGS | While driving at 25 miles an hour on a smooth curving road out of a housing area my wife who was driving and my grand daughter in the front passenger seat heard a loud boom that sounded like somthing hit the roof. My grand daughter looked into the back passenger area and said she saw a large buldge in the headliner near the back window on the drivers side. My wife continued driving saftly to the nearest parking lot and parked the vehicle, she got out and inspected the roof and found no dammage of any kind. she opened the back window tail gate and saw a large fist size buldge in the headliner near the open area on the drivers side. She had no idea what happened. There were no waring lights or indicators that indicated a problem and she drove home and showed it to me. When I saw it I thought it was a rear window or curtian air bag that tried to deploy but did not break through the headlinner. I have called the dealer and scheduled an appointment to check it out on thur March 26 at 09:00 2026. I verified that there are no indicators or warning lights that indicate a problem. The service department said it should be safe to drive until then. | Crash: No Fire: No | Unknown |
| Mar 2026 | LANE DEPARTURE,FORWARD COLLISION AVOIDANCE | The front camera mounted near the rear view mirror stopped working which caused several systems to fail. Acura was slow to respond and was not able to complete the repair because the camera was backordered for several months. | Crash: No Fire: No | Unknown |
| Mar 2026 | FORWARD COLLISION AVOIDANCE,LANE DEPARTURE | Constant errors in dash. Cruise control fails while driving. Auto braking no longer works. Warning of other vehicles in blind spots does not work anymore. Many error in dash display regarding the camera and lkas are displayed. | Crash: No Fire: No | Unknown |

| Feb 2026 | POWER TRAIN,ENGINE | While driving at highway speed, the vehicle suddenly lost the ability to accelerate. Immediately prior to this, the vehicle was making an abnormal engine noise, which continued until the failure. "Drive" light turned off and the "Neutral" turned on its own. I tried to get it to shift back to "Drive" and it wouldn't. I pulled off to the side of the highway. The engine stalled and the vehicle would not restart. The vehicle was towed from the highway and we were told to have it towed to Acura dealer in the morning. This incident occurred while Recall 23V-751 (engine connecting rod bearing defect) was open and incomplete. | Crash: No Fire: No | Unknown |
| Jan 2026 | UNKNOWN OR OTHER | We had the recall repair done on the start/stop feature on our MDX and it seemed to work initially. But recently the feature has caused the vehicle to stall at intersections again as it did before. It’s happened at least 3 times in the last six months with the most recent occurrence being on 1/20/2026. These occurrences happen despite the fact that we try to remember to turn off the feature when we start our trip. Each occurrence has stalled the vehicle at a traffic light in rush hour traffic. It’s very frightening and we are lucky that it hasn’t caused an accident or gotten us shot! We live in Texas (funny but not). | Crash: No Fire: No | Unknown |
| Jan 2026 | WHEELS | Factory wheels on Acura MDX cracking at low mileage under normal driving conditions. Structural failure concern. | Crash: No Fire: No | Unknown |
| Jan 2026 | EXTERIOR LIGHTING | The taillights on this vehicle are defective. I have already had one taillight replaced and now the other side needs to be replaced. These taillights are $300 each for parts only. | Crash: No Fire: No | Unknown |
| Jan 2026 | ENGINE | I was merging onto the interstate from another interstate when my car suddenly became limp and would not accelerate. I had zero warning there was anything wrong with my car, only 67,150 miles. I had to coast to the side of the road and it wasn't driveable. I was forced to have it towed to Acura to find out it's a rocker arm oil pressure switch that apparently goes out after 60,000-100,000 miles. Without warning, this is a huge safety issue. There should be a backup switch and notification to get it to a dealer. I had 3 kids in the car, traveling 65 when it suddenly decided to stop accelerating. ZERO warning. It was terrifying. I could have been hit by another car on the interstate, with 3 kids in the car, zero warning to cars behind me that my speed went from 65 to almost nothing instantly. I've always owned Honda cars and this is the first vehicle I've ever had this happen in. Dealership confirmed it was a faulty switch, nothing to do with low oil, dirty oil and I have that in writing. Acrua/Honda should figure out how to alert users that there is an issue before there is an issue. Or put this on the maintenance schedule because I'm terrified to drive this car now. Or how will I know if it's ready to do it again. Again, some type of backup switch that works for a bit until you can get it to dealer. I had to be towed to dealer. Kids had to be picked up. All things that could have been avoided if Honda did a better job. | Crash: No Fire: No | Unknown |
| Jan 2026 | UNKNOWN OR OTHER,LANE DEPARTURE,FORWARD COLLISION AVOIDANCE | Front windshield camera went bad due to overheating. When malfunction it gives multiple warning lights, everything that has to deal with front windshield camera does not work. Ive hearing multiple and multiple stories online and in person that they too is affected by camera malfunctioning. There needs to be a recall on it as it is affecting way too many people. My car is a 2019 with ONLY 47000 miles pretty much still new. Parts plus labor and camera calibration is $2200 | Crash: No Fire: No | Unknown |
| Dec 2025 | FORWARD COLLISION AVOIDANCE,LANE DEPARTURE | Multi purpose camera stops working while in use causing safety features to stop working. Has almost caused a serious accident.Acura is stating it is not an issue they feel obligated to fix. | Crash: No Fire: No | Unknown |
| Dec 2025 | ELECTRICAL SYSTEM,ENGINE | Since the purchase of my Acura MDX 2019, the following problems have been reported to the dealership and to Honda Manufacturing Inc. without any resolution. The dealer shop has replaced recall parts, but the problems persist and have not gone away. The vehicle stalls and stops working while driving. The engine makes knocking/rattling noises upon becoming disabled while driving.The engine would randomly not start when turning it on. When car becomes disabled the dashboard lights up warning lights displaying messages intermittently of the following problems: Anti-Lock Brake System Problem (ABS), Vehicle Stability Assist (VSA), Hill Start Assist, Trailer Stability Assist, Collision Mitigation System, Road Departure Mitigation System, Adaptive Cruise Control, Lane Keeping Assist, Brake System, Brake Hold System, Electric Parking Brake, SH-AWD, Keyless Start System and Power Steering System (EPS) Problems, while displaying ACC and LWKS codes. Additionally, the vehicle runs improperly and shuts down completely making the window, doors, etc, inoperable while passengers are inside locking me in and my entire family for long periods of time. A few times has left me either myself or with my children and dog inside. The only place where I take my car for services is where I purchased it (Chevy Chase Acura). The issues noted are the same reported by the recalls I have received, and I have not taken it somewhere else because of that reason. Nobody can fix them as the problems are manufacturing issues that even Acura/Honda cannot repair. This safety defect can kill or seriously injure me, my passengers, and other drivers on the road. As noted in one of the many recalls the fuel pump defect can cause the vehicle to stop in the highway and could prevent an engine from starting or cause a vehicle to stall while being driven, it potentially increases the risk of a fire, crash, or injury. My car continues to have these issues and nobody is helping me. Please help! | Crash: No Fire: No | Unknown |
| Nov 2025 | ELECTRICAL SYSTEM,UNKNOWN OR OTHER,SERVICE BRAKES | Turned on my car last night and many lights appeared including emissions system problem, electronic brake problem and SH-AWD malfunctioning. All the lights came on at once. According to forums, this is happening with many Acura RDX, MDX models and manufacturer does not have a clear way to repair or resolve the issue. My car has had all the routine maintenance and is scheduled for the 2 recalls to be repaired next week. | Crash: No Fire: No | Unknown |
| Nov 2025 | POWER TRAIN | The transfer case is blown, with metal debris collected in it. This has caused the all wheel drive to not work because the transfer case is not sending any power to the rear wheels. The car dashboard doesn't register that that transfer case isn't working, so it it thinks the all wheel drive is working, when it isn't. A bad transfer case can cause the car to lose control or traction when it needs to use the all wheel drive system or completely stop while on a highway because it can lead to damage to other parts of the power train. This has been confirmed by an independent service center. There are no warning lights telling me the transfer case is blown or that there are any issues with the power train. The only sympton I noticed was a high pitched sound when driving. These symptoms first appeared about 3 weeks ago. | Crash: No Fire: No | Unknown |
| Oct 2025 | STEERING | Loud clunking noise when steering, possibly the rack and pinion. Control arms and struts have been replaced. | Crash: No Fire: No | Unknown |
| Oct 2025 | ENGINE | My car has failed to restart while sitting at red lights. The engine complete shut down. This has happened twice now since I have owned the vehicle. The first occurrence was around March 2024 and the most recent occurrence was 09/2025. Very dangerous situation both times and I had my child in the car. | Crash: No Fire: No | Unknown |
| Oct 2025 | FORWARD COLLISION AVOIDANCE,LANE DEPARTURE | Camera is failing - reportedly due to a bad internal ground-wire. Acura is charging $900 for the part and $1600 for the installation and calibration of a new unit !! Also - the unit is a black color, and located right behind the windshield, so bakes itself to death. Acura should be using white colors inside the space, limit the un-used volume, and recalling the units (or at least providing a low-cost unit) to allow simple replacement and improve safety. Such an important AND EXPENSIVE part should not be failing so often. The MXers.org web site has hundreds of posts about this item. ALSO - the parts should be pre-calibrated! Acura wants several hundred $$ to calibrate it and 4 days to do it. NHTSA should NOT be requiring ADAS technology if it is so fragile and expensive to fix/replace, as in the long-run owners will not maintain it (e..g $2,400 repair bills for a small camera part nad 5 minute change). See: https://www.mdxers.org/threads/multiple-errors-that-wont-go-away-adaptive-cruise-lane-keep-assist-road-departure-collision-mitigation-now-with-troubleshooting-and-solutions.182671/ | Crash: No Fire: No | Unknown |
| Oct 2025 | ENGINE AND ENGINE COOLING | The contact owns a 2019 Acura MDX. The contact stated that while at a stoplight with the Auto START/STOP feature activated, the vehicle failed to restart after releasing the brake pedal. The contact stated that the vehicle was able to be restarted approximately 5 minutes later. The failure had occurred on several occasions. The local dealer was notified of the failure, but the cause of the failure was not yet determined. The manufacturer was not notified of the failure. The contact was made aware of NHTSA Action Number: EA25004 (ENGINE AND ENGINE COOLING); and related the failure to the action number. The failure mileage was 1,000. | Crash: No Fire: No | 1,000 |
| Sep 2025 | FORWARD COLLISION AVOIDANCE,LANE DEPARTURE | The front camera responsible for forward collision warning and lanekeep has failed. The camera has part number 36160-TYR-A02. It failed on it's own but it could have been alot worse if it failed before a collision occurred. The dealer and independent repair shop said it was the camera code U3000-49 and this was an out of pocket repair. The symptoms include having these error messages on the gauge cluster. Adaptive Cruise, Lane Keep Assist, Road Departure, Collision Mitigation, and Auto High Beam Problem. At first it would intermittently show up but then after a while those errors would not go away. | Crash: No Fire: No | Unknown |
| Sep 2025 | VISIBILITY/WIPER | We just got into the vehicle and was driving down the road when the sunroof exploded. Nothing hit it and nobody was around us when it happened. I about went off the road. Didn't know what happened. Very scary that a sunroof can just explode on its own with nothing hitting it. | Crash: No Fire: No | Unknown |
