In December 2024, I was driving my 2024 Honda Accord Hybrid Sport on a clear, dry day after school when the car just completely lost power out of nowhere. The dashboard went crazy, flashing a bunch of different error messages every few seconds. Because the car wouldn't respond, I ended up in a side-impact crash. I was able to turn on/off the car after putting on my hazards and I was able to drive it normally and drove it towards the side of the ramp. I called my dad and after some time and turning the car on and off, the error messages disappeared and I was able to drive it safely back home. I tried to file an insurance claim (State Farm #51-78K9-28M) back then, but they blamed my driving because the Recall TN2 (Campaign 25V785) hadn't been announced yet. …

The vehicle is experiencing an immediate and severe safety hazard due to a total electrical and mechanical failure within the steering column assembly. The driver horn has stopped working entirely, leaving the vehicle with no way to audibly warn pedestrians or other drivers in an emergency. Additionally, all integrated steering wheel auxiliary controls and buttons are completely non-functional, which points to a failed clock spring/cable reel or an electrical short inside the steering column. This total system failure creates an unacceptably high risk of a collision and raises severe concerns regarding whether the driver's steering wheel airbag will properly deploy in an accident. The vehicle is currently un-driveable, legally unsafe to operate under state transit laws, and induces extreme driver anxiety. …
1. The service center diagnosed the BCM as faulty. I do not have the faulty part available as it was replaced. Service center work notes: Vehicle no start confirmed, battery voltage is at 12.4V. Vehicle has message on dash to touch key to ignition start stop button, with no success. Proceeded to inspect all main fuses to under hood fuse box, found all fuses are good main 175 amp fuse is ok, along with all four multi fuses. Proceeded to follow troubleshooting for message displayed on dash, tested key fob for unlock and lock functions, tested start stop button functions with no issues. Checked fuses that power is at each supply pin, pin 1 on connector a has 12.2v and pin 18 12.3v.

The vehicle's infotainment system displays error code TT04 on every startup, preventing over-the-air software updates, including any potential safety-related updates delivered through this system. The TT04 telematics error appeared immediately following dealer service department completion of fuel pump recall service (NHTSA campaign 24V-763) on 4/12/2025. The vehicle exhibited no infotainment or telematics issues prior to this recall service. This suggests the recall repair procedure either was performed incorrectly or has an inherent flaw that damages the Telematics Control Unit (TCU) communication system. When I returned for subsequent recall service (NHTSA campaign 25V-785), the dealer dismissed the issue as 'normal' and refused repair, only offering to address it after I filed a formal complaint with management. …
