2018 Acura TLX Driver assistance Problems

I’ve bought my 2018 Acura TLX used from Holiday Mazda in [XXX] in XXX Now that my nightmare with the Auto Engine Idle is over(the shop that replaced my starter in November 2025 some how got it so it doesn’t work anymore. But that’s not my issue. I’ve had this issues 5-8 times in the last 2 years. I will be driving and my top screen in in the dash(it usually displays navigation, CarPlay, etc) will turn off and flash a couple times. Then it take out my “radio” screen. It’s like it’s resetting because the screens remind me when it electronics reset snd start up. It goes for a total of 2-3 times. Thank the Good Lord my car keeps driving safely. Here is the second issue. I’ve had my parking, forward collision, and the one where it says” object approaching.” Off for 2 years now. When they are on they will start beeping and freaking out. I’ve cleaned in front of wheee those cameras are located. I’ve researched online. And can’t figure it out. Now that I have my newly licensed son ([XXX] old) driving the car I want to get every safety issue working. Acura can’t figure it out and so I don’t know Where else to turn. A fiend recommended I do This. I do have video of these things happening. I can included them if asked to. Thank you. Ps. I wasn’t able to upload video, I can email them if you send me an email address I’ll get it to you asap. INFORMATION REDACTED PURSUANT TO THE FREEDOM OF INFORMATION ACT (FOIA), 5 U.S.C. 552(B)(6)

I was rolling up to a stop light at approximately 20 mph when the frontal crash mitigation feature suddenly slammed the brakes on fully to a complete stop. I searched the web and found that there are other owners of this model that have had similar occurrences. I could easily have been rear-ended if someone had been following. I was lucky that didn’t happen. Since that day, I have been afraid to drive the car until I have disabled the feature.So every time I start my car I have to disable this mode. There is no known fix. No technical service bulletins etc. regarding this problem. Honda Acura needs to find a solution to this. I should not have to disable a safety feature that is actually making my car unsafe!

I got 5 lights on my dash stating that I have an auto high beam problem, road departure mitigation system problem, collision mitigation system problem, lane keeping assist problem, and adaptive cruise control problem. I got these lights on my dash at the exact same time and this happened 1 week after my car alarm started going off randomly. I will now have to change my windshield camera sensor. Seems like this is an issue with many Acura owners.

While I was driving in the fwy I tried changed lanes and needed to speed so that incoming car wouldn’t hit me but my car was stalling. It has happened 3 times!!! I took it to the dealership and they said it’s the camera and that they don’t have the part on stock. I asked for a rental car meanwhile we wait for the part and they said they can’t do that. I stated to them that the car is dangerous not only for me but for the public if I keep driving it like that. They said there’s nothing they can do!

In September 2023 went in for an oil change. Next day all My CMBS, ACC, LKAS and Road Departure Mitigation System all light up on my dashboard as well brake system light. I called and took the car in they said that it had something to do with the camera sensor. I left a complaint and the manager called after I explained to him he said he would call me back. 1.5 years later he never called back. In October 2024 my car alarm started going off for no reason. I took it in and $1000 to fix. Seems like a lot of electric issues with this car

My CMBS, ACC, LKAS and Road Departure Mitigation System all light up on my dashboard as well brake system light. I had a alignment done on my car about 2 weeks ago and the next day they came on. I went back to the shop where I had the alignment done to ask why they came on. They check the alignment again and said something about calibrating the sensors and checked that again. But the lights didn't go off.

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 was driving and a lot of warning lights came on, on the dash and 10 different warning messages in the message center. The alignment instantly messed up jerking my car to the right and I had to try to gain control and correct. Luckily, I was only going about 25-30mph and was able to correct. If this would have occurred moving faster the outcome could have been very different. Dealership is stating it is the P-AWS actuator on my 2018 Acura TLX that have gone out and caused this to occur. Appears to be an issue many have encountered with two different Acura models according to what I have found online and a costly repair of $6,000. Someone could really have been hurt with this issue if going at a speed of normal driving or on a freeway.
