Acura RDX collision warning problems

Filed Sep 1, 2025 · Driver assistance, Electrical · MA

While driving at highway speed, all of a sudden I lost all power steering and multiple system failure warning lights appeared on the center dashboard including power steering failure, brake system failure and collision mitigation system failure, among others. With great difficulty I was able to steer the car off the highway and was towed to an Acura dealer. The car was 5 months old with just over 3000 miles at the time and there were no prior issues and no advanced warning when this happened. The dealer (Acura of Berlin in CT) stated they have seen this issues several times. The battery voltage was low (11.98-12.09 volts), although the car was being driven at highway speeds for at least 45 minutes before the incident. They charged and tested the battery, and their diagnostics said the battery was good. They also found a code "DTC U3000-49 EPS CONTROL UNIT INTERNAL CIRCUIT MALFUNCTION". The dealer opened an incident with the Acura Tech line, who indicated that if the problem happens again they should replace the steering rack. No repair other than battery charging was performed. This is an unacceptable safety risk waiting for it to happen again. There are many reports of this exact problem online from 2025 Acura RDX owners. We need an immediate recall.

While driving my 2025 Acura RDX A-Spec Advance (approx. 5,000 miles) at about 40 mph through a light curve, the vehicle suddenly lost power steering mid-turn. The dash displayed: “Electric Power Steering System Problem. Steering Assist Not Available. Do Not Drive.” This was not just a loss of assist. The wheel felt like it was resisting input and was nearly impossible to turn, locking the car into an off-road path. I narrowly missed a curb and a large tree by inches, only avoiding collision by forcing the wheel with maximum effort while applying heavy brakes. If this had occurred at higher speed or on a mountain road, the result could have been catastrophic. Once stopped, five additional warnings appeared: Brake System Problem, Lane Keeping Assist System Problem, Collision Mitigation Braking System Problem, Road Departure Mitigation System Problem, and Low Speed Braking Control Problem. After restarting, most warnings remained, though steering assist and brakes seemed temporarily normal. I cautiously drove to a nearby lot, then to the dealership. At the service center, the errors cleared only after shutting down the engine. Staff first suggested a “loose battery cable.” When I mentioned that other 2025 RDX owners have reported the same issue, I was told not to trust the internet. They kept the vehicle overnight under warranty. Initially no loaner vehicle was available, which forced my wife to leave work for daycare pickup. After she called management directly, a loaner was provided. At the time of this report, no diagnosis has been given. Service staff speculated it could be nothing or it could be a failed steering column, which matches reports from other owners. This sudden steering failure, combined with simultaneous warnings across multiple safety systems, created an immediate risk of serious crash. The incident occurred only two days after routine service at the same dealership.

As I was navigating a turn onto a highway on-ramp, the vehicle unexpectedly decelerated or attempted to brake autonomously, accompanied by a sudden loss of power steering assist. This created a hazardous situation, nearly causing a collision with the guardrail. After safely bringing the vehicle to a stop, the dashboard illuminated with numerous warning lights and messages such as: Electric Power Steering System Problem. Steering Assist Not Available. Do Not Drive. Brake System Problem. Brake performance may be reduced. See your dealer. Lane Keeping Assist System Problem. See your dealer. Collision Mitigation Braking System Problem. See your dealer. Road Departure Mitigation System Problem. See your dealer. Low Speed Braking Control Problem. See your dealer. The power steering light and brake system lights came on.

I started driving on the freeway for a few miles in the rain and suddenly started to hear a low rumble/rattling sound from the engine area. The car began to cycle through error messages for every one of the electronic safety systems (Brake system, vehicle stability assist system, electric power steering system, adaptive cruise control system, collision mitigation braking, & road departure mitigation) The car then began to lose drive power (wouldn’t maintain/increase speed when pressing the gas pedal). I moved over to the furthest right lane/slow lane and continued to lose propulsion from the gas pedal. Being forced to such a slow speed on the freeway in inclement weather was very unsafe for me and my wife who was in the car with me. I had to drive on the shoulder in order to exit the freeway and the engine rattle got increasingly louder and worse sounding. I pulled into a parking lot and the car was not drivable. AAA tow to a AAA certified mechanic repair shop and was told that there was metal debris in the oil pan and oil filter which was signs a faulty engine components that has now destroyed the motor. I’m currently without the RDX and being told it is in need of a whole new motor.
