Honda Ridgeline lane assist problems

Filed Oct 21, 2026 · Electrical · FL

I've been having trouble with the auto start stop on my vehicle pretty much since i bought it. If I don't forget to disable it, when i come to a stop light my truck won't restart and shut off. Leaving me scrambling to restart it while i have cars flying by me. I've taken it to the dealership multiple time. They've changed the throttle body when it was under warranty, that didnt fix it. they've changed the battery, that didn't fix it. Also when it happens a bunch of warning lights come on for power steering, lane assist, hill decent braking etc.. Then when i turn the vehicle off they all disappear. I've done research on this and its a known problem with other honda years and models. Why this hasn't been recalled and fixed I have no idea, but I am genuinely afraid for my and my childrens safety.

The vehicle's front-facing monocular camera experienced an internal component failure that triggered a permanent error code U3000-49. This hardware failure instantly disabled multiple core safety features simultaneously, including the Adaptive Cruise Control, Lane Keeping Assist (LKAS), Road Departure Mitigation, and Collision Mitigation Braking System (CMBS) ABS Braking and High Beam Support with all dash lights remaining on. The sudden, unexpected loss of automatic safety braking and driver-assist features while moving poses an immediate highway safety risk.

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

Multiple warning lights appeared and remained illuminated on my dash, all related to safety features (LKAS, ACC, CMBS AND ROAD DEPARTURE). The problem was confirmed by Capitol Honda Service Department. The vehicle was scanned and stored DTC was found at INTEGRATED DRIVER SUPPORT SYSTEM. U3000-49 MULTIPURPOSE CAMERA UNIT INTERNAL ELECTRONIC FAILURE. The DTC was set as hard code, unable to clear. RECOMMEND REPLACING MULTIPURPOSE CAMERA AND PERFORMING CALIBRATION. The estimate I was initially given for the cost of the repair parts and labor was close to $2,000. The repair was necessary because the inoperable safety features directly affects my safety on the road as well as the safety of others. Honda Sensing is a suite of driver-assist safety technologies that use cameras, radar, and sensors to monitor the vehicle's surroundings, alert the driver to potential hazards, and provide automatic steering and braking assistance to help prevent collisions. Key features include Collision Mitigation Braking, which applies the brakes to avoid or mitigate a crash; Adaptive Cruise Control, which maintains a set distance behind the leading vehicle; and Lane Keeping Assist, which provides subtle steering adjustments to keep the vehicle centered in its lane.

This is design feedback. When taking curves to the right on 2 lane highways and especially when the oncoming is a truck, and the forward collision warning set on short, the system experiences a spurious event: BRAKE warning and wheel shake. Lane departure is off. Both vehicles in their lanes. Suggest Honda use right curve inputs (camera right curve view) to reduce the radar scan field to avoid these spurious alarms. I've not had this experience with numerous other vehicles by different manufacturers. On a right curve the radar is looking at the oncoming lane. This should be analyzed and corrected.

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.

My Honda 2020 ridgeline has intermittent faults on the dash monitor, it displays ACC, LKAS, Collision Mitigation, High beam, lane departure warnings, and sometimes transmission problem. I am told it is the muti cable assembly sensor on the front window not communicating with the other sensors. I took my car to auto zone and they stated no communication, due to a bad battery. I replaced the battery, and it still has the multiple errors/ fault codes. During research several people have had this problem with Honda vehicles. At times it goes away for a day or two and then comes back with the same faults. It seems like a faulty part. The dealer wants 1800 for repair and calibration of sensors, this was after they ran a diagnostic test and found no engine faults/codes.
