2012 CHEVROLET SILVERADO Complaints

PARKED FACING UPSLOPE. THE TRUCK SLIPPED OUT OF PARK GEAR AND ROLLED DOWNHILL BACKWARDS, KNOCKING OVER OWNER. FINALLY HIT A TREE AND STOPPED. INSURANCE DECLARED IT TOTALED. *TR

THIS FAULT HAS BEEN PRESENT SINCE THE FIRST WEEK OF OWNING MY 2012 SILVERADO CREW CAB LT EQUIPPED WITH THE 5.3 LITER AND 6 SPEED TRANSMISSION. UPON SLOWING TO A STOP, THE TRUCK SURGES AND LUNGES FORWARD AS THE TRANSMISSION DOWNSHIFTS BETWEEN GEARS, AND IS MOST NOTICEABLE WHEN TRAVELING UP OR DOWN HILLS. THE FAILURE MODE CAN BE TECHNICALLY DESCRIBED AS THE FOLLOWING SEQUENCE OF EVENTS: 1. SLOWING TO A STOP (COASTING), ENGINE BEGINS RIDING OUT 4TH GEAR (FOR EXAMPLE). 2. APPLY BRAKES; TRANSMISSION DOWNSHIFTS TO 3RD, AND ENGINE RPMS INCREASE TO COMPENSATE FOR DYNAMICS OF SHIFTING. TORQUE CONVERTER IMMEDIATELY ENGAGES THE ENGINE TO THE WHEELS. AS THE ENGINE IS AT A HIGH RPM LEVEL, AN ACCELERATING LOAD IS APPLIED TO THE WHEELS, WHILE BRAKING. 3. THIS CREATES AN UNINTENDED SURGE OF ACCELERATION, WHICH IS THEN ALSO NOTICEABLE THROUGH THE REMAINING GEARS (TRUCK SLOWS, THEN SURGES, SLOWS, THEN SURGES UNTIL COMING TO A COMPLETE STOP). I HAVE ALSO VERIFIED THAT THIS IS A COMMON COMPLAINT IN THE ONLINE FORUMS, AND MANY PEOPLE ARE EXPERIENCING THIS FAULT. IN FACT, ONE OF THE DEALERSHIPS ACTUALLY INFORMED ME THAT MANY OF HIS CUSTOMERS GO TO AN AFTERMARKET SHIFT PROGRAM TO AVOID THE ISSUE. I HAVE TRIED THIS, AND IT DID NOT RESOLVE THE ISSUE. EACH TIME THE TRANSMISSION IS EVALUATED AT THE DEALERSHIP, THE DAPS (DIGITAL PARAMETERS) ARE "RESET" (ACCORDING TO THE SERVICE SHOPS), AND THE TRUCK DRIVES FANTASTICALLY. HOWEVER, ROUGHLY 10 MILES LATER, IT IS BACK TO EXHIBITING THE EXACT SAME FAILURE MODE. DEALERSHIP HAS TROUBLESHOOT THIS FAULT EXTENSIVELY, AND HAS STATED THAT THIS MODE OF OPERATION IS "NORMAL" - I ASKED THEM TO EXPLAIN HOW FORWARD ACCELERATION DURING BRAKING WAS "NORMAL", AND OF COURSE THEY COULD NOT. *TR

EFM ISSUE: LIFE-TIME CHEVY SILVERADO OWNER, CURRENTLY OWN 2003 & 2012 1500 SILVERADO 1/2 TONS. EVER SINCE GM STARTED USING EFM CHIPS, FOR SOME UNKNOWN REASON THE ENGINE WILL LOSE SEVERAL QUARTS OF OIL FOR NO REASON. WITHOUT WARNING THE CHECK ENGINE LIGHT COMES ON. PULL-OVER & CHECK THE OIL LEVEL. ON EVERY OCCASION, (SEVERAL INCIDENTS NOW), MUCH TO MY SURPRISE THE OIL LEVEL BARELY REGISTERS ON THE DIP STICK. WHERE DID 3-4 QUARTS OF OIL GO? YESTERDAY THE OIL LEVEL WAS FULL, TODAY THE OIL LEVEL IS ALMOST NON-EXISTENT - WITHOUT A DROP OF OIL LEAKING ANYWHERE? I NOW HAVE TO CARRY 3-4 QUARTS OF OIL WITH ME EVERYWHERE I GO JUST IN CASE THE CHECK ENGINE LIGHT COMES ON. GM SHOULD DO THE RIGHT THING AND ISSUE A RECALL. WARNING: IF YOU DRIVE A CHEVY YOU BETTER KEEP 4 QUARTS OF OIL WITH YOU AT ALL TIMES IN THE EVENT THIS HAPPENS TO YOU. NOT IMMEDIATELY PULLING-OVER & FILLING THE OIL LEVEL BACK TO PROPER LEVEL MAY DESTROY YOUR ENGINE. FIX THIS EFM ISSUE > LOSS OF OIL, AS IT HAS BEEN GOING ON FOR YEARS AND STILL PERSISTS AFTER 2 COMPLETE MODEL CHANGEOVERS. THIS MAJOR MALFUNCTION IS THE RESULT OF THE EFM SYSTEM DUMPING THE OIL INTO THE EXHAUST & THE CATALYTIC CONVERTER BURNING IT AWAY. THAT IS THE ONLY PLAUSIBLE EXPLANATION FOR LOSING SO MUCH OIL WITHOUT WARNING AND WITHOUT A DROP OF OIL BEING FOUND ANYWHERE OUTSIDE THE ENGINE OR UNDERNEATH THE ENGINE COMPARTMENT OR CHASSIS. *TR

I BOUGHT MY 2012 CHEVY OCTOF 2013. NOW AFTER 11000 MILES MY FRAME LOOKS LIKE A TRUCK OUT OF THE 80'S. I TOOK IT BACK TO THE LOCAL DEALER. THERE FIX IS TO SCRAPE OFF THE RUST AND PUT THE SAME CRAP BACK ON THE FRAME. SO I KNOW THAT THIS ISSUE WILL ONLY LAST A VERY SHORT TIME. *TR

I HAVE BEEN HAVING PROBLEMS WITH MY CHEVY SILVERADO TRUCK, TEXAS EDITION, IT HAS 23,800 MILES ON IT I PURCHASED IT WITH O MILES, I ADHERE TO OIL CHANGES AND ANY REPAIRS IN TIMELY MANNER. MY TRUCK HAS BEEN IN SERVICE DEPARTMENT TWICE FOR THE SAME ISSUE, WHEN THE TRANSMISSION IS SWITCHING GEARS, IT MAKES A CLUNKING NOISE WHILE DRIVING IT, IT FEELS LIKE SOMEONE IS BUMPING THE REAR OF TRUCK. THE REPAIRS INCLUDE TRANSMISSION HARD SHIFTING 2 - 3 TIMES, RR UPPER CONTROL VALVE BODY AND SPACER PLATE REPLACED, RESET TRANSMISSION, 1 2 3 4 CLUTCH REGULATOR VALVE BINDING IN BORE. ALSO REPLACED SPRINGS, SECOND SERVICE THE U JOINTS ANITSD YOKE REPLACED, MY TRUCK CONTINUES WITH SAME PROBLEM, PLEASE LOOK IN TO THIS ITS HORRIBLE & VERY DISAPPOINTING WHY CAN`T THEY FIX IT, MY TRUCK SOUNDS LIKE AN OLD VEHICLE I THINK SOMETHING IS WRONG WITH SUSPENSION. I`M DESPERATE TO FIND AN ANSWER. ITS AN EXPENSIVE TRUCK TO BE DEALING WITH THESE ISSUES. *TR

THIS TRUCK HAS CHATTERED, HOPPED, AND HAD BAD BRAKES AS SOON AS WE DROVE THE TRUCK OFF OF THE LOT. WHEN WE WENT WITH THE DEALER WHO SOLD US THE TRUCK, MY HUSBAND SAID WHY IS IT VIBRATING & HE TOLD US THAT IT WAS IN THE TIRES FROM "SITTING". IT HAS HAD 2 NEW WHEELS & NUMEROUS BRAKES, PADS, ROTORS, CALIPERS, DRUMS. & IT STILL VIBRATES. THE DEALERSHIP HAS EVEN PUT ANOTHER TRUCKS TIRES & RIMS ON THE TRUCK & IT STILL VIBRATES. THIS IS UNACCEPTABLE FOR A NEW VEHICLE. WHEN I CALLED THE GM DISTRICT SPECIALIST ON 5/29/13 SHE TOLD ME THAT THE VIBRATION & HIT & MISS ACCELERATION WAS A CHARACTERISTIC OF THE TRUCK. $40,000 TRUCK & IT IS NOT A VERY GOOD RIDE. *TR

WHEN YOU TRY TO ACCELERATE, THE TRUCK DOES NOT RESPOND. THE TRUCK ACCELERATION FEELS LIKE THEIR IS A FLAT SPOT IN THE ACCELERATION. THIS IS VERY DANGEROUS. SEVERAL OF MY FAMILY MEMBERS HAVE ALMOST GOTTEN IN TERRIBLE T-BONE ACCIDENTS DUE TO THIS MALFUNCTION. BROUGHT THE TRUCK TO THE LOCAL DEALERSHIP & THE SAID THEY REPLACED THE THROTTLE POSITION SENSOR & IT IS WORSE NOW. *TR
