Open the full vehicle complaint log (all categories)TOYOTA HAS A FAULTY DESIGN ON 5.7 LITER SEQUOIAS AND TUNDRAS WHERE THE ENGINE CAMSHAFT TOWER SEALANT LEAKS OIL TOWARDS THE CABIN. SINCE THE ENGINE IS TILTED BACK, THE ENGINE OIL IS DIRECTED TO A HEAT SHIELD AND THEN DIRECTLY TO THE EXHAUST PIPE. UPON REACHING THE EXHAUST IT CAUSES SMOKE. THE SMOKE WILL ENTER INTO THE CABIN CAUSING ENGINE FUMES WHICH OCCUR WHEN DRIVING OR PARKED UNTIL THE ENGINE COOLS. THE ENGINE COULD HAVE CAUGHT FIRE, BASED ON THE AMOUNT OF SMOKE THAT CAME OUT. UPON FURTHER RESEARCH, THIS ISSUE HAS CAUSED FIRES. EVIDENCE OF THIS PROBLEM IS READILY AVAILABLE SEARCHING "TOYOTA TUNDRA CAM LEAK FIRE", FURTHERMORE, CHANGE.ORG PETITION HAS OVER 5,178 SIGNATURES REQUESTING THE RECALL. THIS ISSUE HAS OCCURRED IN VEHICLES FROM 1,000 MILES AND UP. TOYOTA NOW USES A DIFFERENT SEALANT TO PREVENT THIS LEAKING, SO THEY MUST HAVE RECOGNIZED THE ISSUE BUT HAVE REMAINED SILENT. UPON CONTACTING TOYOTA, THE CUSTOMER SERVICE REPRESENTATIVE STATED THAT HE "HAD NEVER HEARD OF THIS PROBLEM". THE DEALERSHIP THAT IS FIXING THIS HAS A NUMBER OF EXPERIENCED MECHANICS THAT DO SEE THIS OFTEN. IT IS UNSAFE TO DRIVE WITH THIS CONDITION AND THE COST TO REPAIR IS OVER $3,000!
