  • Unknown Or Other 10/15/2025

    The Multipurpose Camera had an Internal Electronic Failure. Indications we all of the warning lights were illuminated on my dash. Initially it began when I had about 43, 400 miles on my truck. The warning lights would all remail lighted on starting the vehicle. I could restart the vehicle and eventually get the lights to go off. Then the slowly began to stay on permanently. I eventually made an appointment and took my truck into a Honda dealership and it was diagnosed a the failure of the Multipurpose Camera at 44,000 miles. The Honda Service Tech told me that none of my safety features were working at this time which really scared me. The Honda Dealership witnessed the dashboard warning lights and ran a diagnostic indicating the problem. The dealership ordered a replacement camera and replaced it. Parts and Labor were $2118.78. The first indication was when the warning lights began staying lit on my dash.

  • Lane Departure, forward Collision Avoidance 07/30/2025

    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.
