2013 Toyota Tundra Engine Problems

Your secondary air injection system has repeatedly failed, causing your check engine light to come on three times. You've replaced multiple sensors and are now on your third pump replacement, and you've lost engine power at highway speeds—which nearly caused an accident. Toyota has redesigned the connection where the hose attaches to the pump, suggesting they acknowledged a design flaw. Fixing this will likely require replacing the air injection pump and hose assembly.

Your vehicle failed a safety inspection due to a faulty air injection pump, and your check engine light came on. The air injection pump helps reduce emissions by injecting air into the exhaust system. The issue was detected at 64,000 miles. Fixing this will likely involve replacing the air injection pump and clearing the check engine code.

Your cam tower uses a rubber sealant instead of a traditional gasket, and this rubber deteriorates over time, causing engine oil to leak onto the heat shield below it. This is a known issue on the 5.7L engine that requires major engine disassembly to repair. The fix involves replacing the rubber sealant with the same material, which may deteriorate again in the future.

While driving at 70 MPH, your steering wheel and vehicle started shaking noticeably. You safely pulled over and found power steering fluid leaking from the engine area. A mechanic confirmed an engine leak was causing the problem, and your check engine light came on after you got home. The issue will likely require identifying the source of the leak and replacing the damaged seals or gaskets to stop the fluid loss.

PLEASE HELP

AT ONLY 64000 MILES MY 2013 PLATINUM TUNDRA HAS A CAM TOWER LEAK. THIS IS A FIRE HAZARD AND NEEDS TO BE ADDRESSED ASAP.

CAM TOWER OIL LEAKS ON BOTH DRIVER AND PASSENGER SIDE - OIL LEAKING ONTO TO MANIFOLD CAUSING SMOKE - POSSIBLE FIRE RISK - NUMEROUS COMPLAINTS WENT UNANSWERED, FINALLY DIAGNOSED BY THE DEALER, HOWEVER TOYOTA NOT WILLING TO FIX AS VEHICLE IS OUTSIDE OF MANUFACTURER'S WARRANTY - THIS IS A KNOWN ISSUE!!

TRUCK HAS ISSUES WITH DELAYED STARTING. MOTOR WILL TURN OVER BUT WILL NOT START IMMEDIATELY FIRST THING IN THE MORNING. HAVE TO TURN ON AND OFF SEVERAL TIMES BEFORE SUCCESSFUL START. HAVE BEEN TOLD THAT THE PROBLEM MAY BE THE FUEL PUMP AND THIS COULD BE CRITICAL WHILE DRIVING AS THE PUMP MIGHT FAIL AT SPEED CAUSING COMPLETE POWER LOSS. ISSUE BEGAN ON OR ABOUT 12/03/2018 AND CONTINUES TO PRESENT.

TL* THE CONTACT OWNS A 2013 TOYOTA TUNDRA. THE CONTACT NOTICED SMOKE COMING FROM THE ENGINE. THE CONTACT CHECKED UNDER THE HOOD AND NOTICED THAT THE CAM SHAFT TOWER SEAL WAS LEAKING ONTO THE EXHAUST. THE DEALER (DAVID MAUS TOYOTA, 1160 REINEHART RD, SANFORD, FL 32771) STATED THAT THE VEHICLE WAS NOT INCLUDED IN ANY RECALLS AND DID NOT ASSIST. THE MANUFACTURER WAS NOTIFIED. THE VEHICLE WAS NOT REPAIRED. THE FAILURE MILEAGE WAS 87,000.

CRANKED TRUCK AND CHECK ENGINE LIGHT CAME ON. UPON COMPUTER DIAGNOSTICS, FIND OUT THERE IS A PROBLEM WITH THE EMISSIONS SYSTEM - STUCK AIR INJECTION CONTROL VALVES. AFTER VISITING TWO SHOPS AND TALKING TO TWO MORE I FIND OUT THIS IS AN EXTREMELY COMMON PROBLEM. THERE ARE LITERALLY TENS OF THOUSANDS TUNDRA'S, SEQUOIA'S, ETC WITH THE EXACT SAME PROBLEM. THERE HAS BEEN NO RECALL, BUT TOYOTA HAS SET UP CUSTOMER SUPPORT PROGRAMS (CSP'S) TO REIMBURSE SOME OF THOSE AFFECTED BY HIGH REPAIR BILLS $3,000 - $5,000. THIS WAS OBVIOUSLY A VERY POOR DESIGN BY TOYOTA THAT'S BEEN DUMPED ON THEIR CUSTOMERS. MY VEHICLE IS NOT COVERED BY THE CSP.

CAM TOWER GASKETS (RIGHT AND LEFT) LEAKING @ 25,000 MI/5 YEARS ON EXHAUST MANIFOLD CAUSING SMOKE AND A FIRE HAZARD. TRUCK WOULD NOT PASS MAINE STATE INSPECTION BECAUSE OF THE OIL LEAK.

CAM TOWER LEAK -OIL LEAKING ON MOTOR

WHEN THE ENGINE STARTS IT HAS A VERY NOTICEABLE KNOCKING NOISE ON THE PASSENGER SIDE THAT NEVER GOES AWAY. YOU PUT IT IN GEAR AND YOU CAN REALLY HEAR THE ENGINE KNOCKING, AND THE KNOCKING SPEEDS UP AS YOU ACCELERATE. EVEN AFTER THE ENGINE WARMS UP COMPLETELY YOU CAN STILL HEAR IT KNOCKING(STATIONARY, OR IN MOTION) . ALSO MY GAS MILEAGE IS HORRIBLE! I AVERAGE ABOUT 12.3MPG EVERY TANK. THE BEST MPG I HAVE EVER SEEN IS 13.4 MPG AVERAGE WHICH IS RIDICULOUS EVEN FOR A FULL SIZE TRUCK. I ALWAYS LOVED TOYOTA VEHICLES AND EVER SINCE I WAS YOUNG I ALWAYS WANTED A TOYOTA TRUCK BECAUSE I THOUGHT THEY WERE THE TOUGHEST OUT THERE, BUT AFTER OWNING THIS 2013 TOYOTA TUNDRA I'M DISGUSTED.

OIL LEAK AROUND CAMS. THIS IS A COMMON PROBLEM NOTED ALL OVER THE INTERNET - BOTH 4.6 AND 5.7 LITER MOTORS. TOYOTA REFUSES TO COVER IF YOU ARE NOT NOTIFIED OF THIS PROBLEM AFTER 60K MILES OR 5 YEARS. OIL LEAKS ON BOTH SIDES OF THE MOTOR ON TO THE EXHAUST. THE DATE I NOTED BELOW, IS ONLY WHEN THE DEALERSHIP TOLD ME. I BELIEVE THIS HAS BEEN HAPPENING FOR SOMETIME NOW. I JUST REACHED 60K+ WITH MY LAST OIL CHANGE AND WAS THEN REPORTED TO ME -- I BELIEVE WITH THAT INTENTION.

VEHICLE AT 23199 MILES, STILL UNDER WARRANTY-CAR STATIONARY, SMELLED BURNING OIL AND NOTICED THE OIL LEAK FROM BOTH SIDES OF THE WHEEL WELL ABOVE THE HEAT SHIELD. VEHICLE WAS DIAGNOSED BY A DEALER AND CAM TOWER SEAL WAS LEAKING FROM BOTH SIDES. THEY ALSO FOUND VALVE COVER WAS LEAKING AS WELL. THIS WAS A GREAT SAFETY CONCERN DUE TO FIRE HAZARD. FACTORY DEFECT DUE TO INSUFFICIENT SEAL APPLIED TO THE MATTING SURFACES. DEFECT REMEDIED AND MAJOR REPAIR WAS COMPLETED. THEY HAVE CHANGED ALL THE GASKETS AND SEALS ON THE ENGINE.

CONTINUOUS OIL LEAK FROM CAM TOWER ONTO EXHAUST MANIFOLD. DEALER DENIED THE ISSUE EVEN THOUGH THE SIGNS ARE VERY OBVIOUS. A CALL TO TOYOTA TO GOT ME NO WHERE. THEY DENIED THE ISSUE LIKE THE DEALER. THERE IS OIL ON THE ENGINE BLOCK AND ALSO THE EXHAUST MANIFOLD IS BLACK FROM THE ALL OF THE OIL DRIPPING. AFTER DRIVING FOR AWHILE THE CAR SMELLS LIKE IT'S BURNING. THERE IS A VERY REAL POTENTIAL FOR FIRE. THE ISSUE APPEARS TO BE WIDESPREAD. A QUICK INTERNET SEARCH CAN FIND EXTENSIVE EXAMPLES. TOYOTA APPEARS TO BE REVERTING TO IT'S OLD WAYS AND NOT TAKING RESPONSIBILITY FOR SERIOUS SAFETY ISSUES.

I WOULD LIKE YOUR HELP IN ASSESSING THE POSSIBLE DANGER FROM AN ACTIVE EXCESSIVE OIL LEAK FROM THE CAM TOWER ON THE 2013 TUNDRA. THIS RELATIVELY NEW TRUCK LEAKED OIL ALL OVER THE ENGINE WITHOUT MY KNOWLEDGE UNTIL I BROUGHT IT IN FOR SERVICE. I WAS TOLD THIS COULD HAVE LEAD TO AN AUTO FIRE AND SINCE I AM A DISABLED SENIOR THIS IS TERRIFYING. A BRIEF REVIEW OF THE INTERNET LITERATURE SHOWS THAT THIS LEAKING CAM TOWER SEAL IS A COMMON PROBLEM AND CAN HAPPEN REPETITIVELY BECAUSE OF A MANUFACTURE DEFECT IN THE CAM TOWER COVER AND SEALS. MY QUESTION TO YOU IS THIS A COMMON PROBLEM AND IS THERE REALLY A DANGER OF FIRE? IN SHORT SHOULD I THINK ABOUT BUYING A NEW TRUCK AND IS THERE ANY INVESTIGATION TAKING PLACE AT THIS TIME. THANK YOU FOR YOUR HELP AND ASSISTANCE AT THIS TIME. *TR
