2008 Toyota Tundra Power Train

2008 TOYOTA TUNDRA. CONSUMER WRITES IN REGARDS TO GRINDING NOISE FROM VEHICLE. *LD *JS *JS

TL* THE CONTACT OWNS A 2008 TOYOTA TUNDRA. WHILE DRIVING VARIOUS SPEEDS, THE POWER TRAIN WOULD MALFUNCTION WHILE IN FIRST, SECOND, AND SIXTH GEARS. THE FAILURE CAUSED THE TRANSMISSION TO ERRONEOUSLY DOWNSHIFT AND THE VEHICLE JERKED AND HESITATED. THE CAUSE OF THE FAILURE WAS NOT DIAGNOSED. THE VEHICLE WAS NOT REPAIRED. THE MANUFACTURER WAS NOT NOTIFIED OF THE FAILURE. THE FAILURE MILEAGE WAS 108,000.

ABNORMAL NOISE AND VIBRATION IN RIGHT REAR WHEEL AS VEHICLE WAS IN MOTION. TOYOTA DEALER IDENTIFIED RIGHT WHEEL BEARING AS DEFECTIVE AND REPLACED IN MAY 2017. DEALERSHIP HAD PROBLEMS REPLACING BEARING AND ALSO CONTACTED TOYOTA CORPORATE TO SEE IF REPAIR COULD BE COVERED-TOYOTA REFUSED TO COVER THE ISSUE. THE REPLACED BEARING FAILED AGAIN IN JUNE 2017 WITH A CLICKING SOUND WHICH INCREASED WITH SPEED. DEALERSHIP IS REPLACING RIGHT REAR BEARING UNDER THEIR WARRANTY. I REPORTED PROBLEMS TO TOYOTA CONSUMER ADVOCATE WHO ADVISED ME THAT THERE IS NO RECOURSE OR ESCALATION SINCE THEY HAD NO RECALLS, SERVICE BULLETINS OR WARRANTY COVERAGE DOCUMENTED. I PROVIDED NHTSA COMPLAINTS AND EVENTUALLY I LOCATED TSB T-SB-0151-10 TO TOYOTA CORP. MY CONCERN IS THAT A BEARING FAILURE CAN RESULT IN A LOSS OF STEERING CONTROL OR WHEEL SEPARATION FROM THE VEHICLE. I HAVE NO ASSURANCE FROM EITHER TOYOTA OR THE TOYOTA DEALER THAT THE REMAINING 3 BEARINGS ARE FREE OF THE SAME DEFECT OR THAT THE NEW REPLACEMENT WILL BE SUCCESSFUL. WEB SEARCHES HAVE INDICATED THAT THE PROBLEM HAS BEEN DOCUMENTED BY OTHER PARTIES AND GENERALLY UNSUPPORTED BY TOYOTA.

WE BOUGHT THIS VEHICLE USED IN FEBRUARY, 2012 WITH 33,000 MILES ON IT. A BULLETIN CAME OUT IN JUNE, 2010 (#T-SB-0151-10) ABOUT REAR WHEEL BEARINGS GOING ON 2007-2010 TOYOTA TUNDRA AND THE REPLACEMENT KIT. WE WERE NOT TOLD ABOUT THIS WHEN BOUGHT FROM DEALERSHIP. WE NOW HAVE 92,000 MILES ON IT AND HOWLING HAS STARTED IN THE BACK END AND DEALERSHIP SAID IT IS THE WHEEL BEARINGS--KNOWN ISSUE BUT STILL HAVE TO PAY OVER $1600 TO GET THEM REPLACED. TOYOTA CUSTOMER SERVICE NO HELP AT ALL SAYING OUT OF WARRANTY AT 36,000 MILES/3 YEARS EVEN THOUGH THEY KNOW THE WHEEL BEARS WERE JUNK AND THEY UPGRADED THE BEARING KIT WAY BACK IN 2010. WHEEL BEARINGS ARE A SAFETY ISSUE THE WHEEL CAN COME OFF IF NOT REPLACED. NO HELP FROM TOYOTA COMPANY OR DEALERSHIP. CALLED TOYOTA AND CASE #161110029.

I RECENTLY HAD A LOUD HUMMING NOISE COMING FROM THE REAR DRIVETRAIN OF MY 2008 TOYOTA TUNDRA AT ALMOST ANY SPEED AND THE SOUND WAS PRESENT REGARDLESS OF TURNS OR TYPE OF DRIVING. I HAD NOTICED THE NOISE FOR QUITE A WHILE BUT IT STARTED TO GET SO BAD THAT YOU COULD FEEL A VIBRATION IN THE FLOORBOARD. THE TRUCK ONLY HAS 75K MILES ON IT AND IT TURNS OUT THE REAR AXLE BEARINGS HAVE FAILED PREMATURELY. THIS IS A KNOWN ISSUE TO TOYOTA (SEE TSB-0151-01) BUT AFTER ASKING THEIR DEALERSHIP AND CALLING THEIR RECALL CENTER, THEY REFUSE TO ASSIST FINANCIALLY WITH THE REPAIR, WHICH WAS VERY EXPENSIVE. I BELIEVE THIS IS A SAFETY ISSUE ON THIS VEHICLE, AS THE BEARING COULD SEIZE OR COME APART, POTENTIALLY CAUSING AN ACCIDENT. PLEASE CONSIDER HAVING TOYOTA ISSUE A RECALL. ALSO, PLEASE NOTE THERE ARE QUITE A FEW COMPLAINTS ABOUT THIS ISSUE ON ONLINE CHAT FORUMS.

I HAVE 2008 TOYOTA TUNDRA THAT HAS DEVELOPED A REAREND WHINE/HOWLING NOISE AT HIGHWAY SPEEDS. I HAVE HAD IT TO THE SELLING DEALERSHIP 5 TIMES AT WHICH THEY HAVE ULTIMATELY REBUILT THE ENTIRE REAREND. IT DID NOT FIX THE PROBLEM AND THEY ARE SAY NOW THAT I HAVE TO LIVE WITH IT. TOYOTA CORP. WILL NOT ACT. THIS DOES HAVE A TSB. TOYOTA HAS A PROBLEM WITH TUNDRA REARENDS AND WILL NOT ACT. THERE ARE MANY POSTINGS ON THE INTERNET ABOUT THIS ISSUE. PLEASE HELP IF YOU CAN. I AM AT THE POINT OF NEEDING LEGAL ASSISTANCE. *LN

WHILE IN PARK AND WITH ENGINE RUNNING AND PARKING BRAKE ENGAGED, AFTER ABOUT 5 SECONDS VEHICLE SUDDENLY ROLLED BACKWARDS DOWN AN APPROXIMATE 10 DEGREE SLOPE AND CRASHED INTO A BUILDING. MY WIFE AND 3 CHILDREN WERE IN THE VEHICLE (FORTUNATELY ALL WERE WEARING SEAT BELTS) AND SUFFERED MINOR INJURIES. *TR

WHILE SITTING AT STOP LIGHT AND ONCE YOU LET GO OF THE BRAKE THE TRUCK JERKS WITHIN THE WHOLE DRIVE SHAFT FROM FRONT TO BACK. *TR

WE BEGAN LEASING OUR NEW TOYOTA TUNDRA 12/07. WE NOTICED THUMPING IN THE DRIVE TRAIN AND COMPLAINED OF THE THUMPING TO TOYOTA DEALER 4 TIMES PRIOR TO 12/08 AND THEY CONTINUED TO SAY NOTHING WAS WRONG. THERE WAS AN ACCIDENT 12/08. WAS DRIVING ON ROAD THE VEHICLE LOST CONTROL AFTER LOCKING UP. DEALER HAD VEHICLE FOR ALMOST 2 MONTHS REPAIRING ACCIDENT DAMAGE. UPON RETURN THUMPING CONTINUED AND REAR TIRES WORE OUT IN A FEW MONTHS AFTER PURCHASE OF NEW TIRES (ORIGINALS NEEDED REPLACED PREVIOUSLY). RETURNED VEHICLE TO TOYOTA, THEY CHANGED REAR END HOUSING 4/09. INSURANCE PAID AS CONTINUED DAMAGE FROM 12/08 ACCIDENT. THE THUMPING IS STILL CONTINUING AND APPEARS THERE IS SOMETHING STILL WRONG WITH THE VEHICLE. WE DID COMPLAIN TO INSURANCE COMPANY THAT WE FELT THE ACCIDENT WAS DUE TO AN AUTO DEFECT IMMEDIATELY FOLLOWING THE ACCIDENT. THEY WERE TO DO AN INVESTIGATION. NOW I AM BEING TOLD IT WAS CLOSED BUT WERE NEVER INFORMED OF RESULTS OF THE INVESTIGATION BY ALLSTATE. WE ARE UNSURE WHAT STEPS TO TAKE AT THIS POINT BUT ARE DISSATISFIED WITH THE PERFORMANCE OF OUR VEHICLE STILL AT THIS POINT AND FEEL DEALER AND INSURANCE COMPANY HAVE BEEN OF NO HELP. *TR

I HAVE A 2008 TOYOTA TUNDRA WITH A 4.7 L ENGINE AND 5 SPEED AUTOMATIC. ON TWO SEPARATE OCCASIONS, I HAVE HAD THE TRUCK IN PARK ON A VERY SLIGHT INCLINE, AND THE TRUCK HAS SUDDENLY STARTED ROLLING BACKWARDS. *TR

1. TURNING RIGHT IN 2008 TOYOTA TUNDRA OUT OF PARKING LOT AT WORK OR INTO TRAFFIC, I DECELERATE PREPARING TO TURN RIGHT AND REMOVE PRESSURE FROM GAS PEDAL AND BRAKE DURING THE TURN. WHEN I REAPPLY PRESSURE TO THE GAS PEDAL DURING THE TURN THE TRUCK DOES NOT ACCELERATE ONLY THE ENGINE ACCELERATES. ADDING ADDITIONAL PRESSURE TO THE GAS PEDAL ONLY CAUSES THE ENGINE TO ACCELERATE MORE. WHEN THE TRANSMISSION ENGAGES THE TRUCK SURGES FORWARD SUDDENLY. 2. THIS SLIPPING IN THE TRANSMISSION HAPPENS EVERY DAY. THE CONSEQUENCE OF DRIVING THIS VEHICLE IS WHEN WILL THE TRANSMISSION SLIP AND WHEN WILL THE TRANSMISSION ENGAGE. 3. HAVE TALKED TO THE DEALER (2) TWO TIMES ABOUT THIS ISSUE AND THE DEALER TELLS ME IT IS NORMAL FOR THIS VEHICLE TO REACT IN THIS MANNER. THE DEALER SAYS THERE IS NOTHING THEY CAN DO ABOUT THIS PROBLEM. *TR

THE LEFT FRONT WHEEL BEARINGS AND THE RIGHT REAR WHEEL BEARINGS FAILED AFTER 16,800 MILES ON MY 2008 TOYOTA TUNDRA. THE VEHICLE WAS OUTFITTED WITH A FIFTH WHEEL HITCH AND FACTORY TOWING PACKAGE. IT WAS USED SEVEN TIMES TO TOW A HEARTLAND RV FOE APPROXIMATELY 4K MILES. THE TRAILER WEIGHT AND TONGUE LOAD COMPLIED WITH THE SPECS. IN THE OWNERS MANUAL. ALL REPAIRS WERE COMPLETED UNDER THE TOYOTA WARRANTY. THE DEALER COMMENTED THAT FIFTH WHEEL TOWING IS PROHIBITED ON THE 2010 MODEL WHICH HAS THE SAME REAR END. *TR

THE TRANSMISSION AND TRANSFER CASE ON OUR 2008 TUNDRA 4WD DRIVE HAS FAILED, REPEATEDLY THIS PAST WEEK WHILE OPERATING THE VEHICLE ON A PUBLIC STREET. IN THIS "FAIL" CONDITION, THE TRANSFER CASE MAKES A GRINDING NOSE, THE TRANSFER CASE ALARM BUZZER MAKES NOSE AND IRRESPECTIVE OF TRANSMISSION POSITION OR TRANSFER CASE SELECTION (2WD, 4WD HI, 4WD LO) FAILS TO ENGAGE IN LOW OR HI, AND MOST TROUBLING, THE VEHICLE WILL ROLL IN ANY GEAR, NO GEAR WILL ENGAGE, AND THE CAR CAN ROLL FORWARD OR BACKWARDS OUT OF CONTROL. I WAS ALMOST HIT A BY A CAR TODAY BECAUSE I COULD NOT GET THE TRUCK TO ENGAGE IN ANY GEAR, IN ANY SETTING, INSPITE OF ATTEMPTS TO ROLL THE VEHICLE SLIGHTLY DOWN THE HILL TO ALLOW FOR THE TRANSFER CASE TO ENGAGE, AS SUGGESTED IN THE OWNER'S MANUAL. WHILE I AM NOT PLEASED WITH THE (FAILED) CONDITION OF THE DRIVE TRAIN FOR THIS NEW TRUCK, THIS IS AN ISSUE I WILL ADDRESS DIRECTLY WITH TOYOTA. IN THE FAIL CONDITION OF 4WD, THE TRANSFER CASE MERELY 'BEEPS' AND REFUSES TO ENGAGE TRANSMISSION, RESULTING IN A FREE-ROLLING, UNCONTROLLED VEHICLE. HAD THIS FAILURE HAPPENED TODAY AS WE ATTEMPTED TO ENTER THE FREEWAY, WE WOULD HAVE LIKELY BEEN IN A ACCIDENT. THIS IS UNACCEPTABLE. I AM MOST CONCERNED THAT OTHER TUNDRA OWNERS (AND THE SIMILAR SEQUOIA) WOULD HAVE A LOSS OF VEHICLE CONTROL AND POWER, RESULTING IN INJURY OR DEATH. HOW TROUBLING TOYOTA WOULD PUT THIS VEHICLE ON THE ROAD WITHOUT ADDRESSING THIS ISSUE. *TR

BOUGHT A NEW 2008 TOYOTA TUNDRA DOUBLE CAB 5.7 LITER V-8 4X4 HAD 52 MILES ON IT AUG 8, 2008. DURING THE DRIVE HOME FROM THE DEALERSHIP THE TRANSMISSION EXHIBITED THE RUMBLE STRIP VIBRATION UNDER LIGHT ENGINE LOAD AS DESCRIBED IN THE QUOTE FROM AUTOMOTIVE NEWS OCTOBER 22, 2007 - 12:01 AM ET I FOUND ON THE WORLD WIDE WEB. SEE QUOTE BELOW. MOTOR TREND ALSO MENTIONS IT IN AN ONLINE REVIEW. I EXPECT THE DEALER WILL FIX THIS ISSUE BUT OTHER ONLINE BLOGS SUGGEST THE ISSUE CAN BECOME SEVERE ENOUGH TO PREVENT SHIFTING INTO OR OUT OF GEAR. IF THE REPORTS ARE CORRECT THIS BECOMES A SAFETY ISSUE POSSIBLY STRANDING DRIVER AND OCCUPANTS IN A DANGEROUS SETTING WITH A VEHICLE THAT WON'T MOVE. TOYOTA SHOULD ADDRESS THIS AND CURRENT OWNERS SHOULD BE NOTIFIED OF THE POSSIBLE SAFETY CONCERN. A GOOGLE SEARCH OF TUNDRA RUMBLE STRIP VIBRATION WILL YIELD INFORMATION ON THE ISSUE. LOS ANGELES TOYOTA MOTOR SALES OFFICIALS HAVE NICKNAMED THE PROBLEM "THE RUMBLE STRIP" BECAUSE THE SLIPPAGE CAUSES VIBRATION SIMILAR TO THE SENSATION OF DRIVING OVER THE WAKE-UP STRIPS AT THE SIDE OF HIGHWAYS. THE RUMBLING USUALLY LASTS SEVERAL SECONDS. BUT THE PROBLEM SOMETIMES WORSENS TO THE POINT THAT SOME OWNERS CAN'T SHIFT INTO CERTAIN GEARS. THE PROBLEM HAS BEEN REPORTED ONLY IN SIX-SPEED TRANSMISSIONS, WHICH ARE LINKED TO THE POPULAR 5.7-LITER V-8 ENGINE. SINCE THE 2007 TUNDRA'S FEBRUARY LAUNCH, THE 5.7-LITER ENGINE HAS BEEN INSTALLED IN 70 PERCENT OF ABOUT 135,000 TUNDRAS SOLD. THAT MEANS THE PROBLEM COULD AFFECT NEARLY 100,000 VEHICLES. *TR

THE TRUCK IS A 2008 TOYOTA TUNDRA 4X4 LIMITED SUPERCREW. THE DRIVE TRAIN THUDS AND CLANKS WHEN ACCELERATING AND DECELERATING. IT IS GETTING PROGRESSIVELY WORSE. THE TRUCK WAS TAKEN BACK TO THE DEALER ON THREE OCCASIONS. THEY ADVISE THAT THEY CAN NOT DUPLICATE THE THUDS AND DO NOT FEEL THEM. I HAVE HAD NO LESS THAN FIVE PEOPLE DRIVE MY TRUCK AND THEY ALL ADVISED THEY CAN FEEL THE NOW VIOLENT BANGS AND THUDS. EARNHARDT TOYOTA SERVICE TECH'S ADVISED THEY DON'T FEEL THE THUDS. IF THEY WOULD JUST TELL ME THE THUDS ARE NORMAL INSTEAD OF LYING TO ME SAYING THEY DON'T FEEL ANYTHING IT WOULD BE MUCH EASIER TO SWALLOW. ON ONE OCCASION I STOPPED ABRUPTLY AND THE DRIVELINE MADE A VERY LOUD NOISE AND FELT LIKE THE ENTIRE UNDERCARRIAGE CAME OUT OF THE TRUCK. I HAD TO PULL OFF THE ROAD DUE TO THE INCIDENT SCARING ME. THE DRIVETRAIN IN THIS TRUCK IS ABSOLUTELY JUNK AND I FEEL DANGEROUS. *TR
