March 5th 2020 I finally recorded a message that had been appearing in my dash board during late night drives. Message read as "Adaptive Cruise Control Problem" "Collision Mitigation System Problem" I notified Honda of North Hollywood service department at the time, and they said they could not do anything to fix the problem unless the message was actively displayed on the dash board during the time of service.

Several times my vehicle would randomly brake abruptly (to a screeching halt) due to a malfunction in detecting cars/objects around me. Luckily I managed to not crash or have other vehicles crash into my car from behind, but it scared me. I've always wondered what the issue was, and was never able to get it resolved because I didn't have proof of the abrupt stops. …

I am an Indiana resident. I purchased a vehicle from a private seller in Ohio (seller operates through an LLC) on 1/16/2026 Fraudulent title activity was discovered by mechanic on 1/26/26 (taken to mechanic due to sudden and unexpected issues) The purchase agreement and price ($9,000) were confirmed via text message; there was no written bill of sale and no "as-is" agreement. Prior to purchase, the seller provided a VIN that belonged to a different vehicle than the one sold. After purchase, I discovered the vehicle has evidence of odometer rollback; the Ohio title indicates "odometer inaccurate," which was not disclosed prior to sale. The vehicle was previously salvage titled and originated from Canada, neither of which were disclosed. The Ohio title lists an incorrect purchase price of $4,000, despite the agreed purchase price of $9,000. …
