2020 Toyota Tundra Fuel System Problems

Your Tundra has stalled and lost power multiple times while driving at highway speeds (around 45 mph), with warning lights and a "Not ready to drive" message appearing each time. The Toyota dealership identified a rough idling code related to low fuel but didn't perform any repairs or explain the cause. The truck died again just three miles after leaving the dealership, putting your family's safety at risk since steering and braking become harder without engine power at high speeds.

Your 2020 Tundra lost power while driving and wouldn't restart after you pulled over. The check engine and traction control warning lights came on. You believe this may be related to a known fuel system issue (NHTSA Campaign 20V682000), though you haven't had the vehicle inspected or repaired. The problem occurred at 34,000 miles and may involve fuel system components that need inspection or replacement.

Your truck won't fuel normally—the gas pump automatically stops after about 2 seconds of pumping, even when you try at different gas stations. This prevents you from filling up your tank completely. The issue likely involves a fuel filler neck or vapor recovery system that may need inspection or replacement.

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.
