2021 Honda Ridgeline: lane keeping assist jerks the wheel

Filed Jul 23, 2026 · Driver assistance · FL

When driving the vehicle suddenly displayed warning and failure lights for the following: Adaptive Cruise Control, Lane Keep Assist, Road Departure, High Beam Support, and Collision Mitigation. The vehicle in the past regularly experiences issues with oncoming traffic (especially on 2 lane roads) when it comes to auto braking and forward crash warnings so I immediately brought the vehicle home as I was worried for my safety and the safety of others on the road that if these systems were now warning of malfunction the vehicle might auto brake in traffic for no reason and cause a crash. I took the vehicle in following this as I looked online and discovered there were multiple recalls on this vehicle for other various issues and I wanted the dealer to fix those in addition to determining if this was part of one of the recalls also. The dealership has diagnosed the issue as the forward multi-purpose camera and is stating it needs to be replaced to correct the safety issues of the vehicle. I reviewed online and found that just a coupe years ago this part was approx $800 and the dealer is not charging over $1600 for the part. The other issue is that I paid for the part and the dealer claims this part will not even ship until August 26 (over a month away). Additionally I have further researched this issue and found that it is a common failure on Honda and Acura vehicles and creates a major safety concern, yet Honda Motors has refused to address the issue and handle this as a recall as it should be done. New vehicles should not be regularly experiencing catastrophic safety system failures regularly and the manufacture not be held liable for the damages and not be able to fix the part or car in a timely manner. The fact the parts are in such short supply and backorder further attests to the common failure of this part. I would appreciate your immediate review and action of this matter to ensure that Honda is held accountable for the major safety failures they have created.

My 2021 Honda Ridgeline Sport experienced failure of the forward-facing Honda Sensing camera system. This camera controls safety features including Collision Mitigation Braking, Lane Keeping Assist, and Adaptive Cruise Control. The failure disables safety assistance features. Honda acknowledged the issue but refused to provide full repair coverage and only offered $941 toward a repair costing significantly more. I believe a safety-related camera failure should be investigated as a potential defect

2021 Honda Ridgeline RTL-E. Part number 36160-T6Z-A62-M1 failure, hard code U3000-49. Results in total loss of Honda Sense Safety system. Including Collision Mitigation Braking System, Road Departure Mitigation System, Adaptive Cruise Control, Lane Keeping Assist System, Traffic Sign Recognition, Auto High-Beam Headlights. This appears to be a fairly common issue across Honda models where the multipurpose camera fails, generally due to heat from exposure to sun. The replacement cost and required re-calibration via the dealer is ~$2000. Living in northern California with extreme heat, I will assume this problem will resurface after a few years resulting in another $2000+ repair.

At 48,000 miles, the vehicle began to experience multiple Advanced Driver Assistance Systems problems, including Adaptive Cruise Control, Forward Collision Warning, Automatic Emergency Braking, Forward Collision Warning, Lane Departure Warning, and Lane Keeping Assistance, which rendered all these systems inoperable. Systems that were designed to mitigate collisions became non-functional, and continuous warnings on the dashboard were a distraction while driving. Dealer scanned the vehicle with a code U300-40 Multipurpose Camera Unit/Millimeter Wave Radar Internal Electronic Failure, and diagnosed a failure of the multipurpose camera, which was then replaced and recalibrated. I have retained the failed unit after paying to have the replacement installed and calibrated. All warning lamps for the above mentioned systems flashed on my dashboard every time the vehicle was started, prior to the dealer repair. The safety of the driver and those around them was affected because repairs for this safety feature suite may be cost prohibitive to some ($2000) and they just won't fix it.

What happened? While driving in the right lane on a two lane highway, I slowed slightly when approaching a vehicle ahead of me. I then started to move into the left lane to pass when the engine stopped (as confirmed by the tachometer quickly dropping to 0 (zero) rpms). In response, I started feathering the throttle and moved back into the right lane where the engine restarted on its own. I then continued my trip without further incident. This happened with approximately 60,000 miles on the truck which was purchased new by me. I did have a similar incident when the truck was much newer but didn't pay much attention as I was still learning Honda's ADAS and wasn't sure if 'pilot error' came into play. And to clarify, the only safety that was in use this time was Lane Keeping Assist but it wasn't active as I was actively signaling my lane change. Questions under your General Guidelines: While the engine stopped unexpectedly, I don't believe it was an engine fault simply due to the number of miles I've driven the truck with no similar problem. While my wife and I weren't at risk since traffic was light at the time with no one behind us, I can see a safety issue in heavier traffic, especially if the engine doesn't restart as soon as it did. The truck has not been inspected by Honda. I did file a complaint with American Honda (case #14787271) and they simply suggested a visit to my local Honda service department. But due to the very limited occurrence of this issue, I can't see how their service department can be of any help. During the incident occurrence, there were no warning lights, messages or otherwise hints of an impending problem.

Vehicle veering constantly while Lane Keeping Assistance is engaged causing persistent swerving and inviding adjacent lanes as well as requiring additional distraction while system is engaged. Adaptive Cruise Control erratically and some times violently applies brakes, causing the following vehicles to constantly apply their brakes to avoid rear collision with the Ridgeline.

While driving at night even with no traffic ahead, the automatic high beams rarely turn on. When they do, they turn off almost immediately due to reflections from road signs and even small road markers. Occasionally, they'll fail to dim in a timely fashion or will flash causing other drivers to think I'm doing this on purpose. Other owners of 2020 and 2021 honda ridgelines are reporting the same useless and unsafe operation. I owned 2017 and 2019 honda ridgelines with automatic high beams and the feature worked reasonably well. From 2017-2019, honda used a dedicated camera for the automatic high beam function. For the 2020 model year, honda eliminated this camera and merged the automatic high beam functionality into the "multi-purpose camera unit" that is also used for other functions such as the lane keeping assist system feature of honda sensing. In short, the new automatic high beam system is not only useless, but offensive to other drivers. I'm afraid the flashing will induce road rage or gain unwanted attention from law enforcement officers. For now, I have disabled the automatic high beam system. The 2021 ridgeline's headlights are already a step backwards according to iihs testing (and my own observations) and I feel like the "high beam assist' credit they apply should be removed since this feature is next to useless since the 2020 model year.
