Acura RDX power steering loss problems

Filed Apr 22, 2026 · Electrical, Steering · MT

I own a 2025 Acura RDX with an open EPS recall involving potential loss of power steering assist due to improper software calibration. I live in Bozeman, Montana, far from the nearest Acura dealer. Acura customer care and escalated supervisor offered no reasonable accommodation. Completing this safety recall requires substantial long-distance travel and lease mileage to repair a manufacturer defect. I am submitting this complaint regarding recall remedy access and owner burden.

Vehicle: 2019 Acura RDX (Technology Package) I am reporting a serious safety issue involving sudden loss of engine power while driving. On March 14, 2026, I filled my gas tank before traveling approximately 1.5 hours out of town. The vehicle operated normally that day. The following morning, during snowy and icy conditions, while accelerating in traffic, the vehicle suddenly lost power and stalled. Multiple warning lights illuminated on the dashboard (“Christmas tree” effect), and the steering became very stiff, making it difficult to safely maneuver the vehicle out of traffic. I was able to restart the vehicle, but warning lights remained on. The next day, while driving on the highway under normal conditions, the same issue occurred again. While accelerating, the vehicle suddenly lost power and stalled in traffic, creating a dangerous situation. In response, the fuel pump inside the gas tank was replaced; however, the problem persists. The vehicle continues to display warning lights and still loses power when accelerating. I contacted an Acura dealership after seeing reports of a fuel pump recall for similar vehicles, but I was told my VIN was not included. Despite this, the symptoms match known fuel pump-related issues. This defect poses a serious safety risk, especially when driving at highway speeds or in traffic, as sudden loss of power and steering assist can lead to a crash. No injuries have occurred yet, but the issue is ongoing and unresolved. I am requesting investigation into this issue as a potential safety defect.

August & September 2025 The power steering stopped while driving and without warning, causing the car to be almost impossible to steer. I happened about 3 weeks ago and the dealer replaced the power steering unit after consulting with the Acura techline. Then after the power steering unit was replaced, it happened again, the same problem. Both times the Lane Keeping Assistance was engaged, so it might be related. The first time I was on a curve and it forced the car into the oncoming lane at night. Fortunately, there was no oncoming traffic or a could have a head-on collision. The second time I was on a highway and moving into the Exit lane, so I was able to pull off the road. Both times, when I stopped the car and turned the engine off and back on, the problem went away, but I got a brake warning that did not seem to affect the driving or the brakes. This is a serious safety problem that is very dangerous and must be fixed by Acura immediately. The local dealer seems to know nothing about the problem. Online there are multiple customer complaints being reported of the same problem.

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.
