The vehicle's dash states the following are malfunctioning: Road Departure Mitigation System, Adaptive Cruise Control, Auto High Beam, Collision Mitigation System, and Lane Keeping Assist. The vehicle is available for inspection upon request. A few days prior to this message appearing on the dash, the car flashed and beeped that I needed to BRAKE when there wasn't anything in front of me while driving. The car automatically braked without me doing anything. There weren't any vehicles behind me in that specific moment. With how sudden the car braked, this could have caused a collision. This vehicle has been repaired by the dealership where it was purchased, for this exact issue. The first sign of sensors malfunctioning was in January 2022 (I purchased the vehicle in June 2021). I have ta

49,622 mark on my 2020 Acura tlx AWD… auto stop was enabled, car was at stoplight, engine attempted to re-engage but did not and car went into “neutral”… and the lights stayed on. I immediately turned on blinkers to avoid crash and and attempted to re start car, I shifted into Park, shut down car and re-started it successfully. I am seeking repair or disablement of the auto stop system, this is a safety hazard to myself and my family as well as others who had to go around while the issue was being troubleshooted. This appears to be related to Investigation:EA25004

the engine failed and lost all power to the car. It is available for inspection. My safety was put at risk because if i was going on a freeway and freeway speeds i probably would have crash and potentially crash into other people, causing a huge safety issue. The problem has been confirmed by dealer. They said it is very possible the engine rod bearing could have caused this. This is being inspected by Acura. Prior to failed there were no warning lamps or indicators. They all turned on once the car died.
The contact owns a 2020 Acura TLX. The contact stated that while operating the vehicle, the check engine warning light, the emission system failure, and electronic parking assist messages were displayed. Additionally, the AWD feature had become inoperable, making the vehicle difficult to steer. The contact stated that the failure was intermittent. After disconnecting and reconnecting the negative battery terminal, the system was reset and the failure was corrected, but eventually reoccurred. The cause of the failure was not yet determined. The local dealer and manufacturer were notified of the failures, but no assistance was offered. The failure mileage was unknown.
Vehicle will suddenly shift into neutral while driving and won’t shift into drive until the vehicle is turned off and restarted
2 1/2 years before the current connecting rod bearing recall, my engine failed due to the connecting rod bearing at 53,000 miles. After fighting with Acura for almost a year, they agreed to replace the motor. However, when I picked it up, they had only rebuilt the motor. Now that motor's rod has failed at 68,000 miles and they refuse to replace the motor. They say it doesn't have anything to do with the connecting rod bearing but it is knocking with a thrown rod.

On or about October 21–22, 2025, I brought my 2020 Acura TLX (brown, 99,000 miles, VIN [XXX] ) to Goodson Acura of Dallas for a recall repair related to engine concerns. The vehicle was returned to me on October 24, 2025. Shortly afterward, the car began to lag and hesitate while accelerating. On November 3, 2025, while driving to a doctor’s appointment on the Bypass Bridge in morning traffic, the vehicle suddenly stalled and lost power completely. This created a dangerous situation in active traffic. I recently underwent surgery following a serious burn injury, so limited mobility made this stall especially hazardous. After restarting the engine, multiple ADAS and system-fault warnings appeared. I contacted Goodson Acura and was advised to bring the vehicle in. Upon arrival, the service
Multiple dash lights including "brake system failure, collision mitigation system problem, adaptive cruise control problem, road departure mitigation system problem, etc." RPMs effected, car does not shift into third gear. Safety of myself and others were at risk because the vehicle stalled then would not go over 20mph. Had this been a busy highway, lack of warning could cause a major collision. The vehicle was recently inspected and passed by Criswell Honda, Gaithersburg and purchased by me today. No dash lights were displayed. I drove less than 100 miles before the issue occurred. The vehicle is currently being towed back to Criswell Honda for diagnostics and repair (or I was told that is what they will be doing).
Warning lamps appeared for forward collision, lane keep assist, auto high beam, brakes, adaptive cruise control.
My wife and I had just turned into Kroger's parking lot and I was looking for a parking space, we were probably going 15~20 MPH. The car suddenly accelerated on its own. I was able to put on the brakes and slow the car down before we hit a pedestrian and/or other cars in the parking lot. We were fortunate that we were on an open stretch of parking lot, this may have turned out really bad. We drove around town after this happened and stopped and restarted the car several times. It has not happened again today.

suspension 1 complaint shown
I've received the recall notice for my car about 2 years ago. I've tried to schedule time with the dealership to get it fixed but they just keep telling me they don't have the parts or I have to wait till something "bad" happens first for them to prioritize me. This seems really unsafe and bad practice. I've reached out to Honda and they have open a case to review this but has not gotten back to me since. The car has stall once and a few times during the engine shut off while stopping, it takes a moment for the engine to come back, not normally like when I got the car. There has been a few time that there were cracking noise while I was driving. I stop driving the car as much as I can to avoid an accident happening. Please help me get some resolution with Honda, it's been almost 2 years.
steering 1 complaint shown
Was driving on the highway at posted 65 and 70-mph when car suddenly went into 'limp mode' to under 50mph and I was forced to exit the highway after nearly being rear-ended. Dash error indicated 'Precision All wheel steering had malfunctioned'. Took the car to Crown Acura in Cleveland where I was told that it would be $9210 to replace two rear wheel steering actuators or $2800 if they used salvage parts. This was a known issue with the 2015-2020 Acura TLX cars and there are numerous reports online in TLX and Acura forums. Had a semi truck been behind me, there is no question that I would have been in an accident and injured if not killed. Acura needs to address this issue with these cars under a federally mandated recall notice.

brakes 1 complaint shown
While traveling on highway, parking brake intermittently activated several times and parking brake malfunction alarm flashed on dashboard. This caused the vehicle to brake unexpectedly while driving through a construction zone on highway 45. Fortunately, we were very close to the Acura dealership where the vehicle was purchased and managed to drive the vehicle to the service department. The Parking brake alarm continued to display on dashboard even after turning off the vehicle and starting it again. The emissions alarm also flashed intermittently on the dashboard. After researching on several TLX Forums, we found similar incidents dating back to 2015 TLX vehicles. There is also an issue when trying to start the vehicle. Sometimes the engine does not turn over and the dashboard disp
