TRACTION CONTROL/STABILITRAC SYSTEM: SERVICE INDICATOR WARNINGS ACTIVATE, SWITCHES FROM 2 WHEEL DRIVE TO 4 WHEEL DRIVE HIGH EVEN THOUGH SELECTOR IS IN 2WD MODE. THE FIRST OCCURRENCE OF THIS WAS AT 70K MILES, THEN AGAIN AT 90K. THEN AGAIN AT 97K THE TRANSMISSION WAS DAMAGED AND NEEDED TO BE REPLACED. AGAIN AT 101K MILES THE RINGGEAR IN THE REAR AXEL WAS DESTROYED. REAR AXEL WAS REPLACED.

CAR STALLED UNEXPECTEDLY ON FREEWAY EXIT FOR NO APPARENT REASON WITH LOSS OF POWER STEERING AND ALL FUNCTIONS. HAD TO COAST TO A STOP AND LUCKILY NO OTHER CARS WERE BEHIND US. *TR ADDITIONALLY, CAR FUEL TANK VALVE DOES NOT STOP GAS WHEN FUELING AND CAUSES GAS TO SURGE OUT OF TANK WHEN FUELED AND ONTO VEHICLE. REPORTED THIS PROBLEM TO DODGE AND THEY SAID THIS VIN NO. WASN'T COVERED BY RECALL.

TRANSMISSION FAILED ON ACCELERATION FROM STOP. BROUGHT TO CHEVROLET DEALER WHO TOLD ME "THE 1ST AND 2ND GEAR CAME APART INTERNALLY" AND THAT A COMPLETE REBUILD WAS NECESSARY. NO PRIOR INDICATIONS OF TRANSMISSION PROBLEMS (I.E. SLIPPING, NOISE, ETC...). WILL COST ME OVER $3000 TO REPAIR. SEARCHING ON LINE, I FOUND SEVERAL OTHER OWNERS COMPLAINING ABOUT THE SAME PROBLEM WITH LESS THAT 90000 MILES ON THEIR VEHICLES. *TR

TRANSMISSION FAILURE, NO WARNING SIGNS. VEHICLE FELT LIKE IT POPPED OUT OF GEAR. TRUCK DOES NOTHING IN DRIVE, ONLY MOVES IN REVERSE, 1ST, AND STILL DOES MAJOR SLIPPING. ONLINE RESEARCH HAS INFORMED ME THAT THIS IS A COMMON ISSUE AMONG THIS TYPE OF TRUCK. *TR

TL*THE CONTACT OWNS A 2007 CHEVROLET AVALANCHE 1500. WHILE DRIVING 65 MPH, THE CONTACT NOTICED WHITE AND BLACK SMOKE THROUGH THE REAR VIEW MIRROR. THE BRAKE PEDAL EXTENDED TO THE FLOOR WHEN IT WAS APPLIED. THE VEHICLE WAS TOWING A TRAILER AT THE TIME OF THE FAILURE. THE CONTACT WAS ABLE TO STOP THE VEHICLE USING THE ELECTRIC BRAKE CONTROLLER FOR THE TRAILER. HE NOTICED FLUID DRIPPING FROM THE REAR AXLE, WHICH THEN CAUGHT FIRE. THE FIRE DEPARTMENT EXTINGUISHED THE FIRE. THE VEHICLE WAS TOWED TO THE DEALER AND THEY DETERMINED THAT A DEFECTIVE PINION SEAL CAUSED THE FAILURE, HOWEVER, THE FIRE DEPARTMENT DETERMINED THAT THE FAILURE WAS CAUSED BY SYNTHETIC REAR AXLE FLUID. THE FIRE DAMAGED THE FUEL TANK, TRAILER, TAILGATE AND DRIVER SIDE REAR QUARTER PANEL OF THE VEHICLE. THE CURRENT AND FAILURE MILEAGES WERE 12,832. UPDATED 01-16-08. *KB THE CONSUMER STATED THE REAR AXLE CAUGHT ON FIRE. THE GAS FILLER TUBE WAS ALSO BURNED. THE VEHICLE HAD 1800 DOLLARS WORTH OF DAMAGE. UPDATED *JB
