2023 Honda Accord Hybrid: lane keeping assist jerks the wheel

Filed Jun 30, 2025 · Acceleration, Electrical · TX

Vehicle Power Loss and System Malfunctions I am writing to formally express my concern regarding a recurring and potentially dangerous issue with my vehicle, 2023 Honda Accord Hybrid. Twice while driving, the vehicle suddenly shut down on the freeway and completely lost power. In both cases, I was fortunately able to steer the car to the shoulder of the road, but this posed a serious safety risk. During these incidents, multiple system error messages appeared on the dashboard, including alerts related to braking, lane departure, and other critical functions. Alarmingly, this same issue has also occurred while the vehicle was parked in my garage. Each time, the only way to temporarily resolve the issue has been to shut off the vehicle and restart it. Upon restarting, the only remaining warning is related to the braking system, along with a prompt to bring the car to the dealership. If the vehicle is restarted again, all error messages disappear. I have contacted my dealership after each occurrence and brought the vehicle in for inspection. My car is currently at the dealership, and I am awaiting information on the cause of the problem and the proposed resolution. After the first time it happened, I have taken video/pictures of the errors and supplied same to the dealership. I consider this a serious safety concern—not only for myself but also for any passengers and other drivers on the road. Quite honestly, I am now afraid to drive the car, knowing that it could unexpectedly shut down at any moment without warning.

I was driving approximately 60 mph on a local highway when my the check engine light came on. The dashboard then started flashing warning messages for multiple error messages stating that many features were failing such as power steering, acceleration, brakes, lane assist, stability assist, and more. My car then lost power and decelerated, coming to a complete stop in the middle of the highway. I was unable accelerate or steer my vehicle to the side of the road. No one hit me but this could have easily caused an accident where either myself or others were hurt. I turned the car off and when I restarted it, my dashboard message stated that I had a brake system problem and that I should see my dealer. I was able to drive to the dealer where they ran a diagnostic and could not replicate the problem. They only stated it was a loss of communication in the computer but that "it would probably not happen again." They did nothing to identify what could have caused the loss in communication and said if it happened again, to bring the car back. I plan to take it to a certified mechanic to inspect the vehicle but I feel very unsafe driving a car that may lose power.

While driving at moderate speed (between 25 and 35mph), the car's dashboard indicated that The Brake System, Lane Departure, Honda Scene, Electric Motor/power Steering, and several other systems were having issues and I should see the dealer. I would have attempted to record these, but I was at an intersection, trying not to get hit. The battery light, tire pressure light, and another indicator (I cannot recall which one) was on. I was able to stop before entering the intersection. After letting up on the break, I did not move forward. I pressed the gas, and still did not move forward. I powered the car off by pressing the power down button after putting the car into park. Upon restart, the Break System error about the "Break Performance being reduced..." was still there and I was able to make my way into a nearby parking lot. I parked, and restarted the car again. The error was still there, but no more indicator lights were on. Inspecting around the car and under the hood, I didn't see anything that stood out. I restarted the car again, and had no lights, but the break message did appear again before disappearing. I was able to drive back home without further incident.

Driving on town road up a hill at about 30 mph when I got a brake system warning and the engine shut off and accelerator did not work. I was able glide to the side of the road (steering worked). I turned the car off and on and was able to continue driving to my destination but the same error message was present along with several others (eg TPMS, lane assist, collision mitigation). After being parked for 1 hour, I started car and there were no error messages and car functioned normally. Brought car to dealer (Westbrook CT Honda) and they ran diagnostic codes but found nothing other than what they described as an older voltage flux. They had never heard of a car's engine shutting off with the break system error. Told me that if it happened again to have car towed in so that there would be no code resets. I can only imagine my fear level if this had happened at 65 mph in the middle lane of a highway! I found a on-line forum where others are describing the same thing. Time for a recall?

I was backing out of my driveway and put the car into drive I accelerated and applied firm brakes to slow the car down cause I forgot my brother. Brake system warning and tire pressure warning popped up and stayed. Turned the car on and off and it was still there. The next day everything was back to normal. Took it to the dealer and they said no codes were stored in the cars computer. Literally the next day a code popped up for the lane keep assist and disappeared 3 seconds later( this never happens usually). Took it to the dealer again but they said they can’t do anything if they can’t replicate the problem themselves. I’m suspecting an electrical issue.

When lane keep assist is enabled high speed steering becomes harder to turn left or right, and get sticky at the center position. This leads to an increased effort needed to turn the steering wheel wheel either left or right past the center position

When driving the car at 45 mph, warning lights came on for: (1)Vehicle Stability system problem. Reduced traction and handling. See your dealer. (2)Electric power steering system problem. Steering assist reduced. See your dealer. (3)Hill start assist problem. Vehicle my role upon brake release. See your dealer. (4)Adaptive cruise control system problem. See your dealer. (5)Brake System problem. Brake Performance may be reduced. See your dealer. While these messages flashed, the car lost ability to accelerate, steer very well, and brake very well. The car came to a stop after it slowed and I slammed on the brakes as hard as I could. I placed in in park, turned it off, and then turned it back on. It drove normally for a few minutes and then another warning light came on for a few seconds. It disappeared and the car drove normally. The dealer said a code showed up but they couldn't replicate the issue. They ended up replacing the battery because they didn't want to give it back to me without a fix. About 4 weeks later, we were stopped on the highway and in park waiting for over an hour. As we sat there, the warning light came on that said, "Electric parking brake system problem. Parking brake not available. See your dealer." The dealer kept the car for 2 weeks, couldn't replicate the problem, and said there were no codes. They offered no fix. 2 weeks after that, the car flashed up a warning light while driving 5 mph in a parking lot. The warning light said that the "Lane assist" was not operational and that I should contact the dealer. I couldn't take a pic of it because it only flashed up for 5-10 seconds. I'm taking the car in later today.

While driving I received a message stating the automatic emergency braking, steering assist, lane keeping assist, braking assist, hill hold, adaptive cruise control all we turned off. Additionally regenerative braking was also turned off. This system problem did not clear after the car turned off and back on. The dealership addressed the issue, but unsure of the cause. All codes were cleared and the system was recalibrated. This is the first incident of this type with this vehicle.
