2020 Honda Accord: lane keeping assist jerks the wheel

Filed Oct 28, 2026 · Electrical · FL

Unknown cause - Heavy Traffic I get all warning lights (idiot) come on. No performance loss but every advisory and caution is illuminated. Tested battery 550amps and regulator was putting out 14 volts so all seemed fine. Check battery terminals and connections, all good. After two days lights go away and everything works fine. When lights and advisory are on, no cruise control, TMPS, lane departure, assisted steering, and anything else in the caution light display doesn't work. Good thing all other aspects of the car work fine. Unable to determine the issue with Why this happens. Seen on line others have had this same issue.

I have constantly had to replace spark plugs within the last year — all lights are on dashboard. Finally took it and got a P0372 code, rough idling and misfiring, and stalling. Car once cut off on me while driving. Took it to the Honda dealership and it is indeed my fuel injectors and gasket. I have tried to get in touch about a possible recall but the Honda Manufacturer are failing to release a recall. With all lights on dashboard, NO features of the car can be used (cruise control, road departure, lane keep assist, collision mitigation, hill start assist, traction control, brake hold, and tpms) I’m looking forward to a recall coming as soon as possible. I have done my research and thousands of people are having the SAME issue, it is frustrating especially with the cost of work having to be done. Nobody should have to purchase a new car because of a defect of the manufacturer or too lazy to investigate the issue. HONDA Salesmen and mechanics all say the same thing about the 1.5L Sports model. Over 3,400 worth of work due to a problem I did not cause.

It is unknown what system failed. While coasting to slow for the stopped car in front of me, the car began aggressively accelerating without warning. Adaptive and standard cruise control were both off. Lane keep assist and road departure were also switched off. Due to the slick nature of the road, the acceleration left me traveling far too fast with little space to stop. After sliding to a stop, I was within a foot from the car in front of me. This failure very nearly caused an at-fault accident which there was nothing more I could do. Note that this happened roughly 40 mins into a drive, which was otherwise uneventful. No warning lights were present before, during, or after the issue. This car has been having phantom braking issues and power loss issues consistently since March and has spent significant time in Honda's hands for this issue. The vehicle has come to a near stop on the highway from the previous braking issues and has lost power, stranding me in traffic on a highway. It is suspected that the same system failure that caused those issues has come back up again. To date, thousands have been spent on repair "guesses" and tow bills with no end in sight to these safety issues. This vehicle has become a liability and, as a result, inspections are strongly encouraged. I have included photos of the floor mats as they were at the time, properly secured and not near either pedal.

During a forward-side lane departure collision in my 2020 Honda Accord, the Body Control Module (BCM), forward collision radar system, braking assist, and Vehicle Stability Assist (VSI) all failed to activate. As a result, the vehicle did not brake, warn, or stabilize before impact. The airbags also failed to deploy during the crash. My safety and the safety of others were put at serious risk, as the vehicle did not respond as designed despite being equipped with these systems. The car is now undrivable but available for inspection. This issue has not yet been confirmed by a dealer due to the car's condition, but similar failures have been reported in other 2020 Honda Accords already under recall. The insurance company did not request vehicle data and did not inspect the systems. There were no warning lamps, alerts, or messages prior to the failure; the malfunction occurred without notice. I am requesting that this vehicle be added to the existing recall list related to BCM and safety system failures.

My blinker won't appear on the dash. My trunk won't open. My back up camera won't come on at all. Can't adjust my exterior lights, stuck on the dimmest setting and can't change. Lights will also flicker and I have no control over it. My radio screen told me to enter a code but wouldn't allow me to. My break system light was on. There is warning reading adaptive cruise control see dealer, automatic emergency braking see dealer, lane departure warning see dealer. Doors locked and unlocked while driving. Air condition wasn't blowing the temperature it said, and acting as it was on low when it was on the highest setting. It is available for inspection upon request. I brought my car into a Honda dealership today. My car had to stay overnight because they were unable to address the problem. There were no prior problems or warnings beforehand. All these problems first appeared when I started my car for the first time on November 14, 2024. These put myself and others at risk because the doors locked and unlocked which could have caused us to get trapped in. The lights not working put me at risk at night because I could not see the road that good.

Have taken my car to dealership 3 separate times for all warning lights illuminated. Last time they replaced the transmission for a CVT belt prematurely breaking and all codes went away for one day. Now all are present again. Emmisions system warning, lane departure warning, cruise control warning, exc. Every single light never goes out. Just spent 6k on a car that had under 100,000 miles because I was told it was the transmission belt only to come home and have the exact issues happen. The day it was taken to the shop, it stalled in the road and almost caused an accident on a major highway. At this point, I'm afraid to drive it.

I am an 81 years old widow and am very afraid to drive my new 2020 Honda Accord. I am regularly experiencing an ongoing intermittent issue where my car stalls for no apparent reason. I've taken it to the Honda garage where I purchased it two times and no one seems to be able to satisfactorily address this concern. The first time I reported it to the shop (4/24/24), the technician didn't even pull it into the garage to investigate it. I assumed they would hook it to some diagnostic device and see if the cars computer would have some record of the fault. Instead, he jumped in, pushed some buttons relating to the lane keeping system (?) and claimed that would fix it, but it did not. I continue to experience the same problems. One example is when I take my car to the car wash, it stalls at the end and starts beeping. No matter what car wash I go to, it's the same awful experience, where they must shut down their equipment and come out to help me get the car restarted so as to get me out of the way and let everyone else out who are now stuck behind me (Very frightening and embarrassing). I've also had the car shut off after hitting some small potholes. It will shut down and requires a few attempts to get it restarted from the middle of the road!again - I then took it back to the Honda garage where I purchased it for a 2nd time (6/3/24) and for some other routine maintenance. This time they told me that maybe it was caused by my Toll-Road EZ-Pass which was mounted to my windshield near the rear view mirror. As you may imagine, I'm beginning to think the reason for the inability to address the issue is either intentional, incompetence, or perhaps I have a lemon..

At least once a month with lane keep assist on, and a vehicle in the lane to my right, an emergency braking maneuver happens automatically. I have to disconnect the system

The contact owns a 2020 Honda Accord. The contact stated while driving 25 MPH, the messages "Lane Departure. See Dealer", "Engine Problem See Dealership”, “High Beam Problem. See Dealer" and other unknown messages were displayed. The vehicle was towed to the dealer, where an unknown fuse was replaced; however, the vehicle started temporarily but the failure recurred. The dealer diagnosed and determined that the transmission needed to be replaced. The vehicle was towed to a transmission specialist, where the transmission was replaced; however, the failure persisted. The contact related the failure to the federal safety agency Campaign Number: 20V771000 (Electrical System, Back Over Prevention, Visibility/Wiper, Visibility, Exterior Lighting); however, the VIN was not included. The vehicle was not repaired. The manufacturer was notified of the failure and informed the contact that they could not assist due to the mileage on the vehicle. The failure mileage was approximately 84,000.

The lane departure has two separate problems with both happen frequently, these are not one-time problems. 1. The system seems to pull the vehicle in the wrong direction. For example, if you the car starts to deft to the left, and makes contact with the left lane line, it feels like the pressure exerted on the steering wheel, or the drivetrain itself, actually pulls the vehicle further left. This has the completely opposite effect of what is intended. This is not 100% of the time. Sometimes lane departure does nude the vehicle back towards the center of the lane as expected. 2. The vehicle cannot safely determine lane markings. It frequently mistakes tar lines on the road as a lane line and attempts to correct the vehicle's course. The vehicle also does not know how new lanes/ending lanes work. It will often see a new lane line, from a lane newly added to the road (like when a lane splits into two), as a lane departure and will direct the vehicle to one of the two lanes regardless of driver steering. Each time this happens I have to be aware and manually steer the car where I want to go, fighting against the lane departure system. The car is available for inspection and has not been inspected by Honda.
