The TPMS display went thermal. It blew smoke out of the unit that is mounted to the drivers side front windshield. We were able to disconnect USB power to the device and roll the windows down to ventilate the cabin and ultimately remove the device from the windshield and isolate it. If we would not have been in the vehicle at the time of the failure this could have been a catastrophic failure between the solar collector and the LiFePO4 battery going thermal. There has been no inspection of the vehicle as we were able to remove the device prior to any serious damage. There were no warnings, the TPMS display simply went dark and quite reporting tire data, then a strong burning smell followed by smoke.

What 2021 Toyota Tundra owners say
Most recent owner complaints, unedited.
Were were driving, my 2021 Toyota Tundra, just stopped running. No check engine lights had come on until the engine stalled as we coasted to a stop on the side of the road. We had it towed to the Central Maine Motor in Waterville, Maine 04901. Central Maine Motor -Toyota service just got my truck in to a service bay today 1/29/26 and in formed me the failure was due to the fuel pressure module and a fuel pump failure. Toyota has other years of vehicles that they have issues recalls for and my truck has the same fuel system and fuel pump as in those year vehicles, but no recalls for my truck, a 2021 Toyota Tundra built in Sept/Oct of 2020.
