1 Adaptive Cruise Control problem

Failure Date: 07/19/2026

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.

2 Adaptive Cruise Control problem

Failure Date: 06/12/2026

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.

3 Adaptive Cruise Control problem

Failure Date: 05/20/2026

Front camera system failed lights that are on are brake system, lane assist lkas and acc.

4 Adaptive Cruise Control problem

Failure Date: 02/22/2026

Forward brake assist, collision mitigation, auto headlight dash lights came on sporadically. As of today the lights are now on constant and unable to clear. Advised that the forward facing camera most likely died and a replacement due to recalibration would be 1500-2000. .

5 Adaptive Cruise Control problem

Failure Date: 02/01/2022

This is a general issue that you can find in the forums of the Honda pilot/ridgeline/passport. Is affecting all of them. Very easy to replicate. When using adaptive cruise control and the person in front of you changes lanes. If that person that moved to another lane slows down your vehicle will slow down too, thinking that the car is still in front of you. This is a huge security risk that can cause a rear-end collision if the person behind you is distracted.

6 Adaptive Cruise Control problem

Failure Date: 06/23/2021

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.
