2024 Honda Ridgeline, VIN [XXX], approximately 21,000 miles. The vehicle has repeatedly failed to restart in traffic after the Auto Idle Stop system automatically shut off the engine. Failures occurred XXX. During one occurrence, I was nearly rear-ended when the vehicle failed to restart as traffic began moving. The vehicle also intermittently cranks abnormally slowly when hot. The starter will crank, pause, then crank noticeably slower. I can intermittently reproduce the fail to start problem by driving until the vehicle is hot, shutting it off, and immediately restarting it. I have two videos of this condition. Honda replaced the battery, but the problem continues. The dealer reports that the battery, alternator, and starter pass diagnostic testing. I provided video documenting the abnormal slow cranking and failure to start, but no repair has been made. My primary safety concern is that Auto Idle Stop automatically shuts off the engine while stopped in active traffic, but the vehicle may then fail to restart, leaving it disabled in a traffic lane. The vehicle has already experienced this failure three times. NHTSA is currently investigating Auto Start/Stop no-restart complaints involving 2020–2025 Honda Ridgelines under EA25-004. INFORMATION REDACTED PURSUANT TO THE FREEDOM OF INFORMATION ACT (FOIA), 5 U.S.C. 552(B)(6)

I am filing this complaint regarding the OEM General Grabber A/T tires (date code 1424) that came with my brand new 2024 Honda Ridgeline, purchased in June 2024. At approximately 16,000 miles, I noticed significant dry rotting and cracking between the treads on all four tires. This was observed right before a planned long-distance trip, raising serious safety concerns. I maintain proper tire pressure and take excellent care of my vehicle, and I live in Vermont where the climate is harsh but not extreme enough to justify this kind of premature deterioration. The dealer referred me to Honda’s 1-800 number, who then directed me to Continental, the parent company of General. Continental opened a case and instructed me to visit a Continental dealer, who confirmed the dry rot but said they need to pull the tires to send them back to Continental for inspection before they decide whether to approve the warranty claim. Meanwhile, I am expected to purchase a new set of tires upfront. This process is not only burdensome but also concerning given the potential safety risk of these tires. Tires with only 16k miles should not be deteriorating like this, and I believe other owners should be aware of the issue. Please investigate the integrity and safety of these tires, as the premature dry rot could pose a serious hazard to drivers.

My Honda CMBS system has false warnings from cars coming from the other lane and road markers setting off the system. I had numerous incidents where the steering wheel shakes and a brake warning illuminates with no possibility of an accident. After this warning the car would automatically brake to stop you. I have taken this vehicle to the dealer twice they said it is perfect. Honda knows this system is defective. In the owners manual they describe all the false warnings. I have experienced every one in the manual. I have begged the dealer and Honda company that I believe the camera mounted in front of the mirror is too sensitive and defective but they won’t replace it. The camera also controls the automatic bright lights and they won’t stay on for more than 6 seconds. I contend that this camera also sets off the emergency braking due to oncoming lights or reflective lights in the road. There is a class action lawsuit over this system up to a 2023 Ridgeline. All I want is a new camera and the Cmbs system to work correctly but Honda won’t repair it. They deny it is defective. They claim they can’t duplicate it. Of course they drive it once and say it’s fine. Please make Honda replace this faulty system
