2008 Toyota Sequoia Engine Problems

A valve spring inside your engine failed without any warning, causing one cylinder to stop working. While this happened at low speed and didn't cause the engine to seize, this is a known issue with Toyota V8 engines from this model year that previously triggered a recall on similar Lexus vehicles. The problem would require either a complete engine rebuild or a full engine replacement, both of which are expensive repairs.

AT 66,000 MILES MY SEQUOIA HAD ENGINE PROBLEM, ( THAT'S WHAT TOYOTA PEOPLE SAID ) I TOOK MY TRUCK FOR MAINTENANCE AND OIL CHANGE IF I SEE THE LIGHT IS ON FOR MAINTENANCE. FRIDAY SEPT 16, 2011 I TOOK IT TOYOTA DEALERSHIP FOR OIL CHANGE AND BRAKE PADS DONE, WED THE 21 OF SEPT, I HEARD A LOUD NOISE AND IT JUST STOP! I WAS DEVASTATED BECAUSE, THEY DIDN'T KNOW WHAT HAVE CAUSED IT, PLEASE HELP! *TR

TL* THE CONTACT OWNS A 2008 TOYOTA SEQUOIA. THE CONTACT STATED THAT HE TOOK THE VEHICLE TO A DEALER FOR UNKNOWN SERVICE IN MARCH 2010 AND IMMEDIATELY AFTER, HE NOTICED OIL LEAKING FROM THE VEHICLE. THE VEHICLE WAS TAKEN BACK TO THE DEALER WHERE THEY WERE UNABLE TO LOCATE THE SOURCE OF THE OIL LEAK. THE VEHICLE WAS RELEASED TO THE CONTACT YET THE FAILURE PERSISTED. THE VEHICLE WAS TAKEN TO THE DEALER A THIRD TIME AND THE DEALER REPLACED THE O-RING. THE FAILURE STOPPED HOWEVER WITHIN SEVERAL DAYS, THE FAILURE RECURRED. THE MANUFACTURER ADVISED TAKING THE VEHICLE TO A DIFFERENT DEALER. THE VEHICLE WAS NOT REPAIRED. THE FAILURE AND CURRENT MILEAGES WERE APPROXIMATELY 10,000.

2008 TOYOTA SEQUOIA LOST POWER WHILE DRIVING AT 65 MPH. I WAS ABLE TO PULL OVER TO SHOULDER ON THE FREEWAY THEN THE CAR LOST ALL POWER, EVEN TO STEERING. TECH SAID IT IS NOT BATTERY, STARTER, ETC... *TR

ENGINE OIL SEEPAGE (OR SLOW LEAK) AT THE CAM HOUSING AND ENGINE HEAD CONNECTION (GASKET SEAM) AREA, ABOVE THE EXHAUST MANIFOLD, ON THE RIGHT-HAND-SIDE ENGINE CYLINDER BANK. OIL FIRST DETECTED AT 9,000 MILES (VEHICLE WAS PURCHASED NEW). CONCERN: POSSIBLE ENGINE FIRE IF THE OIL SEEPAGE BECOMES WORSE OVER THE COURSE OF ADDITIONAL MILES DRIVEN. OIL SEEPAGE SHOULD NOT OCCUR IN AN ENGINE THIS NEW - ESPECIALLY IN AREAS NEAR A HOT EXHAUST MANIFOLD. OTHER SIMILAR TOYOTA V8 ENGINES APPEAR CLEAN AT THE SAME AREA - NO OIL RESIDUE APPARENT IN OTHER TOYOTA V8 5.7L ENGINES OF SIMILAR SPECIFICATIONS. THIS APPEARS TO BE A MATERIAL SURFACE MANUFACTURING DEFECT IN MY VEHICLE'S ENGINE. ENGINE INFO: TOYOTA 5.7L V8 CORRECTIVE ACTION: I TOOK THE VEHICLE TO TOYOTA DEALER TO REPAIR THE SEEPAGE OR LEAK TO AVOID A POSSIBLE ENGINE FIRE (AS A PREVENTIVE MEASURE), AND DEALER TOLD ME I HAD TO CALL TOYOTA. I CALLED THE TOYOTA CUSTOMER EXPERIENCE CENTER 1-800 NUMBER AND THE RECORDING STATED I WAS NOT ABLE TO SPEAK TO A TOYOTA REPRESENTATIVE AND I SHOULD CALL BACK LATER. I HAVE NOT BEEN HAPPY WITH TOYOTA'S CUSTOMER SERVICE. WHEN I ASKED A SERVICE MANAGER AT A DEALER ABOUT GETTING THIS REPAIR DONE UNDER WARRANTY, HE RESPONDED BY SAYING "I CAN'T DO THAT TO TOYOTA." IT IS UNFORTUNATE THAT TOYOTA VALUES ITSELF MORE THAN IT VALUES CUSTOMERS. *TR

AFTER 4,399 MI. THE LEFT EXHAUST MANIFOLD CRACKED AND PRODUCED A TICKING SOUND ON ACCELERATION AND EXHAUST FUMES CAN BE SMELLED THROUGH THE VENTS WHEN FAN IS ON. AS PER DEALERS ADVICE, IT'S OK TO USE VEHICLE PENDING REPAIR. IT'S BEEN 5 DAYS AND THE PART HASN'T ARRIVED YET. CONTACTED DEALER FEW TIMES TO FACILITATE REPAIR. *TR

WHENEVER I DRIVE UP HILL OR JUST SPEED UP, THE BAD SMELL OF ROTTEN EGGS COMES INTO THE VEHICLE INTERIOR EVEN WITH THE WINDOWS ROLL UP AND WITH THE RECALCULATING VENT BUTTON ON. *TR
