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 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.

While driving approximately 35 MPH and exiting the highway, the brakes locked up and the power steering became inoperable. The steering wheel was difficult to turn. The power steering, low brake speed, and Lane Keep Assist warning lights were illuminated. The message “Do Not Drive Vehicle – See Dealer” was displayed. If a vehicle had been behind me it definitely would have hit me. I got to a parking lot and shut off the car. I turned it on and the messages were still there. I called for roadside assistance for a tow. The vehicle was towed to the local dealer, who was unable to determine the cause of the failure; because there were no warning lights illuminated upon arrival. The vehicle was not diagnosed or repaired. The manufacturer was contacted and has no concerns. I am afraid to drive this car as it is on the highway every day.

Picked up the vehicle. on [XXX]... on the way home I was going around a curve on a highway with a semi-truck to my right, when the car suddenly braked autonomously, and the power steering stopped working. I struggled to steer into the curve and then allowed the semi to move ahead so I could safely pull to the side of the road. I had several alarms go off that I had to cycle though to turn off. I fully powered down the car, and when I turned it back on I had 2 alarms that stayed on. Lane Keep Assist warning, and Braking System problem. I returned to the dealership the following morning [XXX] and they could not diagnose nor replicate the issue. I'm being asked to roll the dice by picking up the car today 6/30/25, and gamble with mine and my families safety. This problem need to be fixed!

Driving 45mph. In a slight curve. Steering wheel power steering stops working. Car pulls to right into other lane of traffic. Brakes seem to apply like car is avoiding something. Multiple warnings come on. Like steering problem , lane keep assist failure. Brake system problem road departure problem. Car barely will steer. Limped along to stop. Cut off car and back on and steering came back in. Start driving and braking problem notification comes back on. Braking seems ok other than the wearing. Could have been real bad if other car was coming in other lane.
