2025 ACURA RDX Lane Departure Problems

The problem I am reporting I found reported on the internet. My dashboard lite up with power steering and brake warning lights and told me to contact the dealer. Power steering was lost and braking power diminished. Pulled over and restarted the car several times and steering and braking came back but the warning lights still on. After sitting for an hour while we ate the car started with no warnings and brakes and steering functioning. From what I saw on the internet the problem stems from when the LKAS system is turned on. I found on your site my VIN has the issue I described above. Why hasn't Acura contacted me about the problem ? Seems irresponsible.

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.

Started vehicle in the morning and had driven about 5 miles. LKAS, Adaptive Cruise Control and all other collision avoidance systems turned on. ACC Speed set, but disengaged due to prior braking for the curve. Weather overcast but dry. While turning left around a sweeping curve at about 40mph the vehicle suddenly started emergency braking and trying to turn right into the guardrail on the side of the road. Major force required to keep vehicle in the lane and under control. Power steering went out. Collision braking warning, Power steering warning, LKAS warning, Road departure mitigation warning, Low speed braking control problem, also power steering icon glowed orange, safety system icon glowed orange, Lane keeping icon glowed orange, Brake system icon glowed orange. No place to pull off, continued several miles to a parking lot. Took photos of dash warnings (provided to dealer). Cycled engine power to no effect. Cycled again waiting about 1 minute and opening door to turn off nav display. Upon restart warnings all remain, power steering returned. Drove home and parked for about 1 hour. Upon restart all errors gone and functioning normally. Noted Acura Link sent CMBS Problem! notification. Car now at Acura of Brookfield (WI) for evaluation. All notification on vehicle and Acural Link cleared by time I arrived at dealer. Note vehicle defaulted back to "Normal" drive mode after this event. Had been set on "Comfort" which is normally retained at power cycle.

When slowing as I exited freeway the steering locked up and forced me into right lane. There were lots of warning lights, STOP when safe, steering assist problem, brake system problem, low speed braking problem. I had no power steering but was able to get car into a parking lot. I turned the car off and back on. The warning message said it was a brake system problem and to see dealer. Acura Link showed it was a CMBS problem. After turning the car off and on a couple more times the warnings went away and I was able to drive car to dealership. There were no warnings prior to steering lockup. Dealer told me it was a power steering malfunction. The vehicle is available for inspection at the dealership in Fresno, CA. This happened on [XXX]. Parts have been ordered but not expected to arrive until Monday, Jul 7th, 2025. If there had been a car in the right lane this would have caused an accident. I researched this issue on the internet and have found several reports of the same problem. Some people have had it happen multiple times. I purchased the car [XXX] and there were 4,523 miles on the odometer. INFORMATION REDACTED PURSUANT TO THE FREEDOM OF INFORMATION ACT (FOIA), 5 U.S.C. 552(B)(6)

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!

For the third time now, my steering has locked up and sent my 2025 Acura RDX into limp mode. It is a major safety concern because the car steering locks up and or tries to turn. The first time it occured I almost went into a field because the car was trying to turn right while in the middle of a LH corner at 55mph. The second time was on a country road at around 40-50mph with no shoulder, and this most recent time on a straight country road at 50mph. Two times it has been towed to the nearest dealer and Acura has made major component replacements, including the engine wiring harness, and steering system twice now. I have opened a case with Acura stating the severity of safety concerns I have for myself, my family and other drivers on the road. If someone is not prepared to fight the steering and or strong enough it could very likely cause a crash and injuries. At this point, I don't believe Acura knows exactly what the issue is, since they are making the same repair as they did the first time. There are also other reports of this exact issue being reported online, specific to the 2025 model year.

The contact owns a 2025 Acura RDX. The contact stated that while driving approximately 30-35 MPH and exiting the interstate, 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. The driver pulled over safely. The vehicle was restarted, and the contact continued driving. 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. The failure mileage was approximately 2,000.

Mileage: 2,000

While driving around a curve with the LKAS system engaged the steering wheel locked up causing me to move into the next lane. Many warning lights came on, e.g., Stop brake system malfunction. LKAS malfunction etc. My safety was compromised and I had to pull over and shut the car off. My car is currently at the dealer. They said the power steering mechanism malfunctioned and needs replacing. They had to order the parts.

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.

While trying to steer on the highway steering wheel locked up and received an error that the electric steering was not functioning

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. This incident occurred on April 12, 2025 and then occurred again on April 20th. The dealer took the vehicle in on May 9th and told me they can not reproduce the problem. This has the potential to cause life threatening injuries or even death.

I was going around a curve at 20mph and all of a sudden my steering wheel locked up and so did my brakes and I ended up in a ditch. I took a picture of all the alerts that came up on the vehicle.
