Powertrain (other) reportsComplaints are reports submitted to NHTSA by owners and drivers.

Volume is influenced by how many of a vehicle were sold, how long it has been on the road, and how much attention an issue has received.

After purchasing my vehicle through a bank loan, the frame started to deteriorate resulting in suspension components to come loose and fall off. Lastly, rear driveshaft broke off, leaving me inoperable.

The vehicle was sold with significant rust damage to the underbody of the truck. The truck parts are rusted to a point the suspension, and axel are about to fall out. The truck is leaking gasoline due to the amount of rust. The power steering that they fixed after one day driving it had issues when sold is still having issues leaking fluid. It has been deemed unsafe to drive on road. The dealership sold the vehicle in unsafe conditions, and will not rectify the situation. I have documentation, and photos of the damage to the vehicle.

DRIVING DOWN THE ROAD THE TRUCK ENGINE WILL BE RUNNING WITH NO ABNORMAL SOUNDS, SMELLS, LEAKS BUT WILL ACT AS IF NOT IN GEAR. RPM'S WILL REV BUT TRUCK WILL NOT MOVE. ONLY AFTER PUTTING TRUCK IN PARK (LOTS OF GRINDING NOISES) THEN PRESSING THE 4WHEEL BUTTON THEN BACK TO 2WHEEL (SOMETIMES THROUGH TWO CYCLES) THE TRUCK WILL BACK INTO GEAR AND OPERATE PROPERLY. TOOK IT TO A TRANSMISSION SHOP PUT IT ON THE DIAGNOSTIC MACHINE AND NO ERROR CODES WERE GIVEN TO GIVE REASON WHY THE TRANSFER CASE DISENGAGES RANDOMLY. REPLACED THE TRANSFER SWITCH PER SHOP RECOMMENDATION "JUST IN CASE"IT WAS OKAY FOR ABOUT A MONTH THEN ONCE AGAIN ISSUES STARTED AGAIN JUST THE SAME AS BEFORE.

I PURCHASED THE 2006 VEHICLE USED IN DEC 2013. IN 2014 THE TRANSMISSION WENT BAD. IN 2015 I REPLACED THE TRANSMISSION AND BRAKE PADS & ROADERS.2016 REPLACED THE FUEL PUMP BECAUSE IT ALSO WENT BAD, REPLACED TIRES (NORMAL WEAR), BOUGHT A NEW BATTERY BECAUSE IT DIED. 2017 IT NEEDED TWO HUB BEARING AND BOTH FRONT WHEEL HUB REPLACED. THIS IS AN ONGOING PROBLEM WITH THIS VEHICLE! I JUST FOUND OUT MY AIR BAG SENSOR WILL NEED TO BE REMOVED AND REPLACED. ALL MY MONEY HAS BEEN FLUSHED DOWN TO THIS VEHICLE. I DON'T RECOMMEND ANYONE BUYING A CHEVY TRUCK.

TRANSMISSION SLIPPING. WHEN TRAVELING AT SHIFT POINT 1-2, 2-3 THE ENGINE RPMS SUDDENLY INCREASE THEN RETURN TO NOMINAL SPEED. THE MILEAGE IS WAY TO LOW FOR THIS BEHAVOIR. I BELIEVE GM SHOULD ISSUE (OR PAY FOR) THE PARTS (THE TOUGHENED OR IMPROVED PARTS) TO CORRECT THIS PROBLEM OR RE-REIMBURSE THE CURRENT OWNER FOR THE RETAIL COST OF THE GM (IMPROVED) PARTS IF THE OWNER CHOOSES TO HAVE THE WORK DONE ELSE WHERE. THE SHIFTING ACTION IS NOT FIRM, IT'S SLOPPY. AT TIMES YOU CAN'T FEEL THE SHIFT IN THE CONVENTIONAL WAY BUT YOU CAN HEAR IT.
