There are 6 owner-reported fuel system complaints for the 2020 Toyota Tundrain NHTSA's database. These are unverified consumer reports and may not reflect confirmed defects.
The contact owns a 2020 Toyota Tundra. The contact stated while driving at an undisclosed speed, the vehicle inadvertently lost motive power. The contact was able to pull to the shoulder of the roadway, where the vehicle failed to restart. The check engine and traction control warning lights were illuminated. The vehicle was not taken to the dealer or an independent mechanic. The vehicle was not repaired. After investigating the failure, the contact related the failure to NHTSA Campaign Number: 20V682000 (Fuel System, Gasoline) however, the VIN was not included. The manufacturer was not notified of the failure. The failure mileage was 34,000.
Can not fuel truck normally. Gas stops pumping after 2secs and have confirmed the issues with multiple gas stations.
Vehicle stalled and lost power at approximately 45 mph. Warning lights activated and "Not ready to drive" message was displayed. Vehicle has had 3 other similar episodes all resulting in the vehicle losing power at high speed. Vehicle was towed to local Toyota service dept. where they said it generated a code for rough idling - low fuel. They did no repairs and offered no explanation. Three miles from the dealership the Tundra died in traffic. The safety of my family was certainly at stake and had my wife been driving the vehicle she likely couldn't have steered the vehicle to safety. These are not low speed failures, but rather high speeds.
FUEL PUMP RUNNING WHILE ENGINE IS OFF AND KEY IS TURNED OFF
I ACCELERATED FROM A STOP MAKING A RIGHT TURN IN A NORMAL MANNER TO KEEP SAFELY IN FRONT OF ONCOMING TRAFFIC, I HAD NO POWER ALTHOUGH I KEPT PUSHING THE ACCELERATOR. MULTIPLE LIGHTS FLASHED ON THE DASH. I COASTED TO THE SHOULDER OF THE ROAD. AFTER I STOPPED, ALL THE LIGHTS ON THE DASH HAD GONE OUT BUT THE ENGINE WAS STILL RUNNING. IT RESPONDED NORMALLY AFTER THAT. DEALERSHIP SAID A COMMUNICATION CODE SHOWED BUT WAS NOT RELATED TO MY ISSUE. I HAD THREE OTHER "LOSS OF POWER INCIDENTS" SINCE ALL AT LOW SPEED, EITHER STARTING FROM A STOP OR ATTEMPTING ACCELERATION AFTER A TURN. THE YELLOW TRIANGLE FLASHED THOSE TIMES BUT TRAFFIC DID NOT ALLOW ME TO KEEP PUSHING ON ACCELERATOR. AFTER A SHORT COAST POWER RETURNED. DEALERSHIP REPORTED NO CODE. EXPERIENCE SIMILAR TO DESCRIPTION OF BEHAVIOR OF VEHICLES IN TOYOTA FUEL PUMP RECALL. I BELIEVE IT IS THE FUEL PUMP. DEALERSHIP AND TOYOTA CUSTOMER SERVICE TELL ME I MUST DRIVE IT UNTIL IT "FAILS" AND SHOWS A CODE. SAFETY ISSUE, ACCIDENT WAITING TO HAPPEN.
UPON FILLING UP WITH FUEL AT VARIOUS FUEL STATIONS, WHEN THE PUMP SHUTS OFF AND IS REMOVED FROM THE FILLER NECK, FUEL BEGINS TO COME BACK OUT THE FILLER NECK AND POUR OUT ONTO THE VEHICLE AND GROUND. VEHICLE ONLY HAS 2000 MILES ON IT AND HAS DONE THIS FROM DAY ONE. THE SPILLS HAVE RANGED FROM A CUP FULL TO HALF A GALLON MAKING A HAZARDOUS AND POTENTIALLY DEADLY SITUATION. ANOTHER DEALER IN NM ADVISED SOME TOYOTA VEHICLES HAVE DONE THIS DUE TO A DEFECTIVE OVERFLOW VALVE IN THE FUEL TANK. MY LOCAL DEALER HAS HAD ME RETURN SEVERAL TIMES EVEN THOUGH I HAVE VIDEO EVIDENCE OF THE DEFECT. TOYOTA USA HAS ALSO NOT BEEN HELPFUL WITH TRYING TO FIX THE PROBLEM.
