NHTSA Complaint #11677708 — 2022 TOYOTA TUNDRA

I recently put my boat in the water with my 2022 Toyota Tundra at local boat launch. When I put the boat in the water my truck registered a quarter tank of gas. After launching and loading the boat my truck registered a full tank of gas and would not reset or adjust the fuel gauge once it was on a level surface. I found several complaints on the Toyota forum regarding the fuel gauge improperly reading a full tank after being on an incline and not adjusting once on a level surface. I was forced to disconnect the negative battery cable to reset the fuel sensor. Fast forward the truck was at the dealer on 7/28/2025 for the engine replacement. I asked them to look into the fuel gauge sensor issue and was advised that there is a Toyota TSB for the sensor and it needed a computer reflash, but would not do the reflash at their expense. This is a safety issue that if not corrected may cause individuals to run out of gas while in motion on the highways causing the vehicle to stall causing a collision or road hazard.
