Open the full vehicle complaint log (all categories)Have replaced every part in the fuel system. Pumps, modules, etc. and it continues to have issues. Now a fuel smell issue. These cars have constant issues and need a full recall. Still has issues and have had multiple times it stopped running due to the fuel system issues. Attached is most recent receipt
Truck shuts down after running for about 2 minutes; As if the ignition switch was turned off while driving. I then have to wait about 30 seconds to restart the truck. The truck will not start immediately after shutting off. It acts like something has to reset to allow the truck to start. The truck will do the same thing idling in my driveway. It starts right up; Runs about 2 minutes and shuts off. After 30 seconds the truck will restart. This is a danger on the highway. I do not have remote start.
MULTIPLE RECALLS ISSUED FOR TOYOTA FUEL PUMP BUT NOT THIS YEAR. VEHICLE QUIT WHILE DRIVING, WOULD NOT START, TERRIBLE GAS MILEAGE, AND ROUGH RUNNING. DEALER RAN DIAGNOSTICS AND SAID IT WAS A DEFECTIVE FUEL PUMP (JUST LIKE ALL PREVIOUS MODELS) AND REPLACED IT WITH THE REPLACEMENT USED IN THE OTHER RECALLS.
HARD STARTING ISSUE ON COLD START DUE TO FUEL PUMP/ECU FLEX FUEL ISSUE FFV ENGINE 3UR-FBE. DATA SHOWS READING FUEL ALCOHOL CONTENT @ 56% EVEN THOUGH I'VE NEVER RUN ETHANOL... THIS IS COMMON PROBLEM ID ON MANY TUNDRA THREADS ONLINE. IN ADDITION TO INCREASED ENGINE WEAR ON STARTS, FUEL ECONOMY IS REDUCED BECAUSE ENGINE IS MAPPED TO ETHANOL BASED FUEL INSTEAD OF STANDARD GASOLINE FUEL MAPPING.
VEHICLE EXPERIENCES EXCESSIVE CRANK AND NO START WHEN KEY TURNED DO TO PROBLEMS WITH FLEX FUEL SYSTEM DEALER HAS REFLAGGED TRUCK AND THE PROBLEM IS STILL ON GOING IN MANY VEHICLES
WITH THE MANY TIMES I HAVE SEVERELY TRIED TO START MY VEHICLE IT HAS A HARD START NOT DUE TO OTHER COMPONENTS SUCH AS THE BATTERY OR OTHER ELECTRICAL ISSUES BUT THE FLEX FUEL INTEGRATION IN THE SYSTEM NOT READING CORRECTLY. WITH THE REFLASH DONE MANY TIMES IT WILL STILL NOT RESOLVE THE ISSUE. WITH THE VEHICLE ALWAYS AT A COLD START WEATHER IT WOULD BE A HOT DAY OR A COLD DAY IT ALWAYS SEEMS TO HAVE THE HARD START ISSUE. THIS ISSUE HAS MANY AFFECTS ON DRIVERS SAFETY AND COULD CAUSE SEVERITY ON THE ENGINE WITH FAULTS SOON TO HAPPEN. THE SERVICE BULLETIN IS A START BUT SHOULD BE A RECALL DUE TO THE ERROR TOYOTA HAS MADE WITH THIS COSTING MANY MANY OWNERS TO SUFFER HAVING TO TAKE TIME OUT OF THEIR DAY TO DO THIS AND THE COSTLY EFFECTS IT HAS. THIS REMEDY SHOULD BE HEARD BY EVERYONE IN THE TOYOTA INSTITUTE TO FIX THE ISSUE AND HAVE A HASSLE FREE SOLUTION TO BETTER ASSIST AND MAKE THE TOYOTA OWNER HAPPY TO KEEP ON PURSUING AND BUYING TOYOTA TRUCKS.
