Honda referenced this manufacturing defect in its Service Bulletin 21-055 dated XXX. I have attached a copy of the Service Bulletin. Since this problem is affecting a number of different Honda models, my question is if this admitted manufacting…

   Initially the car would not turn on. We were able to start it but then the engine would not turn off. Shop indicated that the Body Control Module is faulty. Honda of Olathe has the component that malfunctioned as of today 11/1/2024.

There was a warning message indicating "Keyless Start…

    The backup camera has stopped working, at least the imaging part. This makes backing up riskier, especially in parking lots, driveways or where pedestrians may be behind me. I have not been to the dealership yet as it failed today but this seems a common complaint for Ridgeline owners online. I have not had others inspect this problem yet. There was no warning, yesterday worked fine, today it doesn't work. I took a picture of the broken wiring harness at the corner of the…

    The backup camera intermittently works. When put in reverse, sometimes I’ll have a black screen with grid lines, other times just a blank screen. Yes, it is available for inspection. I cannot see persons and property when backing up. I am afraid, in reverse, of running over persons shorter than the vehicle that only the backup camera would pick up. This has not been reproduced or confirmed by a dealer or service station. The vehicle has not been inspected by another entity.…

    The failed system is the Backup camera and the failure can be inspected. Our safety is compromised because we cannot see objects behind the vehicle before or during backing maneuvers. The damage has been reported and confirmed by the Honda dealer as well as an independent. There was no warning of the failure, one day it worked the next day it did not work.
