2025 Honda Accord

I was driving down the highway, and the dash started to flash a message about the vehicle being unsafe to drive, stop driving immediately, call dealer. I was able to stop and then turn left across traffic with limited power; and continued to make my way back to work thinking I could probably get to my parking lot. The dash continued to display warning lights, starting with brake failure, then parking brake failure, and then the whole series of possible failures. I continued to drive about one mile. I shut the power off an powered up twice thinking that might reset the sensors; but they continued to fail. As I continued to drive there was limited power to the throttle, and I eventually coasted through a red light and into my work parking lot where the vehicle shut down entirely, and eventually fully locked up (couldn't start or event put in neutral to push). I had the vehicle towed to back to the dealer, and they diagnosed the problem as a failed transmission cooler. Of note, I had purchased the vehicle brand new less than 3 weeks before this incident and the vehicle had less than 600 total miles on it. There were no prior signs of trouble or warning lights.

Dear NHTSA Representative, I am writing to formally report a recurring and unresolved fuel system issue with my 2025 Honda Accord EX, which I believe may point to a potential manufacturing defect or calibration problem affecting fuel delivery or measurement accuracy. Since purchasing the vehicle, I have observed a consistent and concerning pattern: whenever I refuel the car to a completely full tank, the fuel gauge almost immediately begins to drop. Within 5 to 10 minutes of operating the vehicle—sometimes within 30 minutes—the gauge already loses one full bar. This happens regardless of driving conditions or distance traveled. Under normal circumstances, I would expect a new Honda Accord to retain a full-tank reading for a reasonable period after refueling and to achieve the expected range between fill-ups. Instead, I am experiencing extremely rapid depletion. At best, each full tank lasts me approximately three to four days of moderate driving, far less than a week. For clarity: •I do not idle the vehicle unnecessarily. •I do not run the air conditioner; I usually drive with the windows open. •I operate the vehicle under normal conditions, without aggressive acceleration or excessive loads. Despite routine 125-point inspections and regular maintenance at authorized service centers, no visible leaks or external faults have been identified. Yet, the issue persists unchanged. The dealer’s technicians have been unable to detect a mechanical cause, and the vehicle’s diagnostic systems have not shown error codes related to the fuel system. Given these circumstances, I am deeply concerned that there may be an underlying defect in the fuel delivery system, fuel-pump calibration, or fuel-level sender module, potentially affecting not just my vehicle but others of the same model year. If the system is over-pressurizing or mismanaging the rate of fuel consumption, that would represent both a safety risk and an efficiency failure. I am therefore requesting that t
