2016 flex fuel toyota tundra with 118,00 miles was towed to toyota dealer in Las cruces with a no fuel issue. After the analysis it was determined the fuel pump over heated burning out conector and wiring ,but the pump was still working. According to toyota TSB 0166-19 this is a problem the can arise if the alcohol fuel density ID is not updated. I told the dealer to due repairs on vehicle even though a fuel pump was installed and reflashed at 114,000 miles. Viva toyota of las cruses advicate stated that a reflash is all the vehiles needs and does not desire to change the alchol fuel density to updated ID as per TSB-0166-19, so I am worried I will be operating a vehicle with a fuel pump that will over heat and burn out connectors again. I called Toyota complaints and they told me they cannot make a dealer do any repairs.

Gas tank no longer fills completely in a single squeeze. Each squeeze of the pump only fills up maybe a .25 gallon at a squeeze if I am lucky, but typically less. This results in a complete fill up taking close to a half hour. There are numerous posts on forums such as https://www.tundras.com/threads/gas-filling-problem.38449/, https://www.tundras.com/threads/gas-tank-roll-over-valve-stuck-causes-hard-fuelling-anyone-else.42535/, and many others regarding this issue, with no response from dealers other than sorry. This sounds like a pure manufacturing issue if so many people have issues with their tanks, in a similar fashion.

Fuel gauge provides false inaccurate reading, resulting in stranded situation when fuel runs out. Toyota is aware is issue and has only issued a TSB for limited years when the problem is more wide spread. My daughter has been stranded several times.

I PURCHASED TOYOTA TUNDRA ON 6 NOV 2015. SINCE OWNING THE VEHICLE I HAVE BEEN GETTING 460 MILES TO A FULL TANK OF GAS (38 GALLON TANK). THOSE NUMBERS EQUATE TO 12MPG IN FUEL ECONOMY ESTIMATES. I PICKED THE VEHICLE UP ON 6 NOV2015. THE TRUCK HAD A FULL TANK OF GAS. THE FUEL EFFICIENCY READ 570 MILE FOR A FULL TANK OF GAS. ON 13 NOV I DROVE THE VEHICLE TO FLORIDA. EVERY TIME I FILED UP THE TRUCK WITH FUEL THE FUEL EFFICIENCY READING STARTED TO DECLINE. ON THE FIRST THREE FULL TANK OF GAS, THE READING WAS 540 AND 520 MILES FOR A FULL TANK OF GAS ON 15 NOVEMBER. I TOOK THE VEHICLE TO THE DEALERSHIP ON OR ABOUT 17 NOV. THE SERVICE DEPARTMENT PLUGGED THE VEHICLE UP TO A COMPUTER. THE COMPUTER SENT OUT A REPORT THAT SHOWED THAT THE VEHICLE WAS GETTING 18 MPG. THE SERVICE PERSONNEL TOLD ME THAT I WOULD BE DOING WELL IF I GOT 14MPG. BASED ON THEIR COMMENTS I WAS NOT TO EXPECT ANYTHING OVER 15MPG OVER THE HIGHWAY. ON 25 NOV, I DROVE THE VEHICLE TO FLORIDA. I DECIDED TO MANUALLY TRACK THE MILEAGE IN REGARD TO A FULL TANK OF GAS WITH THE USE OF THE TRIP COUNTER. I TOOK PICTURES OF THE VEHICLE ONLY REGISTERING 12MPG ON A FULL TANK OF GAS. ON A FULL 38 GALLON TANK, I WAS ONLY ABLE TO DRIVE 460 MILES PER TANK. THAT EQUATE TO 12MPG. THE DRIVING CONDITION WAS 74-78 DEGREES; DRIVING ON I95; THERE WAS ONLY THREE PASSENGERS IN THE VEHICLE. I USED 89 OCTANE GRADED GAS.
