I've had multiple failures on this vehicle. First, the engine had a rod knock and Acura gave me a very hard time approving the repair and eventually replacement of the engine. Second, the ADAS system is not working and is a huge safety concern. I keep getting error messages that my road mitigation and lane keeping assist systems do not work. Third, the ABS module system cannot communicate with my ECU and is not working properly. Another safety concern as this controls a lot of the wheel speed sensors, brakes, etc on this vehicle. A quick Google search for acura tlx ABS module repair will bring up pages and pages of people complaining about this very same problem yet Acura is not doing anything about it. This problem also affected other models such as the TSX, TL, RL, and the Oddysey. I've taken my vehicle to several mechanics and they all state that this is a very common problem in Honda/Acura. I'm not sure how Honda/Acura can risk the lives of their customers in this way but it is not safe as this vehicle is my daily commuter that I use for my family.

I have had, for years, Idle Stop/restart failures on my 2018 Acura TLX, too many times to count. One time, I heard the screeching tires of a car behind me stopping to avoid rear-ending me, when the driver thought I was going to proceed through an intersection, only to have the car die. Another time, with my infant in the car, I was nearly T-Boned when the car died failing to get through an intersection after a stop. I've taken the car in for service numerous times. Each time, they either couldn't find the problem, or told me I didn't drive it enough, or needed to keep it on a trickle charger, or that I needed a new Battery. In June of 2022, I received a letter from Acura informing me to get a PGM-FI software update. I did. Last night, the car died attempting to restart on a freeway off ramp (which it has done previously as well I should add). I shouldn't have to explain how dangerous it is having a car die on a freeway off ramp. Acura - FAIL.

Engine fails to start after idle stop, when the idle-stop off button is not engaged, and the battery doesn't have enough power to re-start the vehicle. Essentially, the engine tries to start up at a traffic light/intersection but fails, causing the car to turn off and shift to Neutral without warning. I then have to realize what is happening, shift the car from Neutral to Park, and hit the start button to be able to re-start the car. There is no warning from the car that the battery is going to be unable to keep the car running, so the stall is 100% unexpected. This is unsafe, as the re-start procedure is not intuitive, takes time, and causes cars behind you to start honking. It could very easily cause a crash. Either Acura needs to fix this issue with a battery warning, or provide the option of turning the auto-idle stop off button on permanently (which some members of our government wouldn't like, but would fix the problem and keep someone from being seriously injured). This is also a known issue by Honda/Acura, as many other owners are reporting it: https://www.tlxforums.com/threads/engine-failing-to-start-after-idle-stop.31809/

There are so many lights flashing, my vehicle will not go over 50MPH, My steering wheel is no longer straight its actually to the left. I brought it to Acura and they are stating its a REAR TOE ACTUATOR issue and refuse to cover the $5,100 fee to fix this issue that has had a SAFETY BULLETIN posted for a 2015 TLX. There has been a bulletin about this according to Carvana so ACURA is aware of this issue but refuse to recall this issue. Warning lights are as follow, BRAKE SYSTEM ISSUE, ROAD DEPARTURE MITIGATION SYSTEM PROBLEM, Adaptive Cruise Control problem, VEHICLE STABILITY ASSIST PROBLEM, PRECISION ALL WHEEL STEER PROBLEM, POWER STEERING FAILURE. This vehicle only has 46,987 miles.

When I press the start button with my key fob in range and with a new battery, the car won't start, but makes a rapid "ticking" noise while all of the dashboard lights flicker and other interior and exterior lights turn on. Despite repeated attempts over several hours, the car will not start.

When returning from a 40 mile trip to naples Florida, the vehicle stability system displayed failure warning lights. When I made it back to my condo in cape coral, there was S total system failure locking out the transmission, inability to put the car in neutral, antilock brakes, etc. This could have been a major safety issue had I been on the highway.

The contact owns a 2018 Acura Tlx. While driving at an unknown speed, on three occasions, the steering wheel seized while making either a left or right turn. The brake pedal was applied, but felt stiff and failed to respond. The accelerator pedal was applied, but the vehicle failed to move. In addition, the electrical system, emission, transmission, stability control, all wheel assist, blind spot, cruise control, and lane assist indicators illuminated. The vehicle was towed to Acura of memphis (2611 ridgeway rd, memphis, tn 38119) where it was diagnosed that the vehicle overheated and the automatic start malfunctioned. The vehicle was repaired, but the failures recurred. The manufacturer was not notified and opened case number: 08586429. No further assistance was provided. The failure mileage was 31,081. The VIN was not available.
