2018 Acura TLX: lane keeping assist jerks the wheel

Filed Sep 22, 2026 · Driver assistance, Electrical · TN

I own a 2018 Acura TLX with approximately 41,384 miles. While driving, multiple safety-system warnings suddenly appeared simultaneously, including: Lane Keeping Assist Problem Adaptive Cruise Control Problem Auto High-Beam Problem Collision Mitigation System Problem Road Departure Mitigation System Problem Brake System warning I safely stopped the vehicle, shut it off, and restarted it. The warnings initially disappeared but later returned, including when I started the vehicle to take it to the Acura dealership. An authorized Acura dealership inspected the vehicle and retrieved multiple diagnostic trouble codes, including U3000-49, indicating an internal electronic failure associated with the multipurpose camera/driver-assistance system. The dealership cleared the codes, retested the vehicle, and confirmed that the fault returned. The technician also tested the battery, alternator, starter, and camera ground. The brake system was inspected, and no separate braking problem was identified. The dealership diagnosed a failed monocular camera requiring replacement. Safety concern: Multiple driver-assistance systems became unavailable unexpectedly while I was driving, including collision mitigation, lane-keeping assistance, road-departure mitigation, and adaptive cruise control. The simultaneous failure of these systems creates a safety concern because the vehicle's collision-prevention and driver-assistance features may be unavailable without advance warning. The dealership quoted approximately $2,400 for the camera replacement. The vehicle has only 41,384 miles. I have photographs and video documenting the dashboard warnings, as well as the dealership's diagnostic trouble code report and repair estimate. These records are available upon request. I am submitting this complaint to document the unexpected failure of multiple driver-assistance safety systems and request that the federal safety agency evaluate whether this represents a potential safety-related defect.

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.

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.
