2014 Chevrolet Silverado Powertrain & Transmission Problems

HERE'S MY STORY FOR THOSE THAT WILL LISTEN. I PURCHASED THE VEHICLE BRAND NEW AND A FEW DAYS LATER I MENTIONED TO THE SALESMAN THAT IT DROVE UNUSUAL AND HE REPLIED THAT IT COULD BE FROM SITTING ON THE LOT...SO I WAITED FOR THE FIRST SCHEDULED MAINTENANCE AND LET THEM KNOW THAT THERE WAS SOMETHING NOT RIGHT WITH THE SHIFTING OF THE VEHICLE. I NOTED THAT IT WAS LOUD CLUNKING AT DOWNSHIFT FROM 3RD TO 2ND GEAR AND ALSO A CLUNK SHIFT WHEN THE VEHICLE APPROACHES A COMPLETE STOP. THE DOWNSHIFT IS SO HARD THAT IT IS FELT IN THE BRAKE PEDAL. THIS IS THE PART TO ME THAT RAISES THE SAFETY CONCERN. THE RESPONSE WAS THAT THEY CHECKED IT AND THAT EVERYTHING WAS NORMAL. I WAS INFORMED THAT IT SHOULD GET SMOOTHER AS IT BREAK IN. THEY WENT ON TO SAY IF I BRING THE VEHICLE IN FOR THE SAME ISSUE AND NOTHING IS FOUND THAT I WOULD HAVE TO PAY A DIAGNOSTIC FEE. SO NOW AT APPROX. 20,000 MILES AND I CONTACTED GENERAL MOTORS. THEY AGREED FOR MORE DIAGNOSTIC AND NOW THERE IS A TECHNICAL SERVICE BULLETIN THAT STATES THAT IT IS A NORMAL CHARACTERISTIC OF THE VEHICLE. NOW THE VEHICLE HAS FEELS LIKE IT GOT WORSE AND DRIVES TERRIBLE AND UNSAFE. MEANWHILE THERE ARE COMPLAINTS ABOUT THIS SAME PROBLEM ON THE INTERNET AND NOBODY HAS DONE ANYTHING ABOUT IT. IT'S FUNNY THAT 2016 SILVERADO IS THE SAME TRUCK BUT WITHOUT THE PROBLEM. GM NEEDS TO MAKE GOOD ON THEIR PRODUCTIONS MISTAKE AND SUPPORT THERE PRODUCT. SILVERADO DRIVERS EXPERIENCING THE SAME CONDITION SHOULD COMPLAIN TO MAKE MANUFACTURERS RESPONSIBLE. PLEASE INVESTIGATE!!!!!!!!!!!!

5/15 RADIO DISPLAY LOST POWER, RECURRED AT LEAST 3 OCCASIONS; 9/15 TRAILERING IN "TOW MODE" ON INTERSTATE AT 58 MPH WHEN VEHICLE SLOWED DOWN AND RPMS INCREASED WHEN STEPPING ON ACCELERATOR; HAD TO PULL OVER ONTO INTERSTATE SHOULDER AND STOP. VEHICLE BEGAN SHIFTING NORMALLY AGAIN- DEALER STATED THAT THEY UPDATED TRANSMISSION SHIFT POINTS AND TCM. 10/15 HARSH SHIFTING AND CLUNKING FROM RIGHT REAR WHEN TURNING RIGHT. 1/16 HARSH SHIFTING AND CLUNKING FROM RIGHT REAR WHEN TURNING - DEALER REPLACED "U JOINT" AND "ADJUSTED COMPUTER SHIFT POINTS. VEHICLE STILL HAS HARSH SHIFT AND CLUNK IN RIGHT REAR WHICH OCCURS DAILY.

WHILE DRIVING DOWN THE HIGHWAY A STABILIZATION CONTROL LIGHT CAME ON BRIEFLY, THEN WENT AWAY. APPROXIMATELY 5 MILES LATER AFTER EXITING THE HIGHWAY, AND GOING DOWN A SIDE STREET, THE TRUCK DIED AND THE STEERING WHEEL LOCKED WHEN I SLOWED AND STARTED TO MAKE A RIGHT HAND TURN INTO A PARKING LOT. THIS HAS SINCE OCCURRED ONCE MORE UNDER SIMILAR CONDITIONS WHILE SLOWING, BRAKING AND TURNING AT LOW SPEEDS AND NOT UNDER THROTTLE.

I WAS MERGING ONTO THE HIGHWAY AND JUST ABOUT GOT UP TO SPEED AND FELT A VIBRATION THAT WITHIN A FEW SECONDS GOT REALLY INTENSE THEN HEARD A POP AND THEN SEVERAL BANGS. I THOUGHT A TIRE BLEW, SO AS I LOOKED UP IN MY REAR VIEW MIRROR TO SEE IF I WAS CLEAR TO GET OVER TO THE SHOULDER, I SAW MY DRIVESHAFT CARTWHEELING ABOUT 8 FT. IN THE AIR AS PEOPLE BEHIND ME WERE SCRAMBLING TO AVOID FROM HITTING IT. LUCKILY THE DRIVESHAFT DIDN'T LIFT THE BACK OF THE TRUCK INTO THE AIR, AND MORE IMPORTANTLY IT DIDN'T GO THROUGH SOMEONES WINDSHIELD BEHIND ME! IT TURNS OUT THAT THE KNUCKLE ON THE REAR OF THE SHAFT HAD SNAPPED, VIOLENTLY VIBRATED AND THE SHAFT DROPPED, RIPPED APART ABOUT A FOOT BEHIND THE TRANSMISSION AND CAME OUT FROM UNDER THE TRUCK. THE U-JOINT WAS STILL IN THE DIFFERENTIAL AND A FOOT OF DRIVESHAFT WAS STILL IN THE TRANSMISSION. I HAD BROUGHT MY TRUCK TO 2 DIFFERENT DEALERSHIPS FOR A VIBRATION AND CLUNKING NOISE IN THE REAR WHEN IT WAS NEW, (1900 MILES) BOTH DEALERS TOLD ME "THEY COULDN'T DUPLICATE CUSTOMERS CONCERN"...I'M A MECHANIC, I'VE WORKED AT DEALERSHIPS, THIS IS WHAT THEY TELL PEOPLE WHEN THEY DON'T WANT THE HEADACHE OF DEALING WITH AN ISSUE. AFTER LOOKING DRIVESHAFT VIBRATIONS UP ON THESE SPECIFIC TRUCKS, I CAME TO REALIZE THAT IT IS A COMMON PROBLEM WITH 2014 AND 2015 GM FULL SIZE TRUCKS. THIS INCIDENT COULD HAVE TURNED OUT MUCH WORSE THAN IT DID...IF YOU OWN ONE OF THESE TRUCKS AND NOTICE A VIBRATION AT ALL, GET IT INTO THE DEALER AND GET IT FIXED IMMEDIATELY, DON'T TAKE THE CHANCE OF HURTING YOUR FAMILY OR SOMEONE ELSE!

VEHICLE VIBRATES AT 72-80 MPH. HAVE TAKEN IT TO THE DEALER 4 TIMES WITH NO POSITIVE RESULTS. THEY RF BALANCED ALL TIRES TWICE, REPLACED ONE TIRE, AND ON THE LAST VISIT DROVE IT 95 MILES AND DID NOTHING. CURRENTLY DEALING WITH GM CUSTOMER CARE REP AND DEALERSHIP. IF THEY CANNOT FIND A FIX, I WILL REQUEST THEY BUY THE VEHICLE BACK.

I BACKED MY TRUCK OUT OF THE GARAGE AND PARKED IN THE DRIVEWAY. I PUT IN PARK AND HAD MY KEYS IN MY HAND. I WENT TO WALK BACK INSIDE THE HOUSE WHEN I TURNED AROUND AND SAW MY TRUCK ROLLING DOWN THE DRIVEWAY. I STOPPED IT AND PULLED BACK UP IN THE DRIVEWAY AND PUT IN PARK AGAIN JUST FOR IT ROLL BACK DOWN THE DRIVEWAY. AFTER I COUPLE TIMES OF REPEATING THIS THE TRANSMISSION FINALLY ENGAGED INTO PARK. *TR

TL* THE CONTACT OWNS A 2014 CHEVROLET SILVERADO. THE CONTACT STATED THAT AFTER PARKING AND EXITING THE VEHICLE, THE VEHICLE ROLLED DOWN A HILL AND CRASHED INTO A TREE. THE AIR BAGS FAILED TO DEPLOY. AFTER INSPECTING THE VEHICLE, THE CONTACT NOTICED THAT THE GEAR SHIFTED FROM PARK TO NEUTRAL INDEPENDENTLY. THE CONTACT WAS AWARE OF NHTSA CAMPAIGN NUMBER: 14V374000 (POWER TRAIN) HOWEVER, THE VIN WAS NOT INCLUDED. THE MANUFACTURER WAS NOT NOTIFIED OF THE FAILURE. THE APPROXIMATE FAILURE MILEAGE WAS 34,000.

THE ABOVE STATED VEHICLE WAS SOLD TO ME, AND I WAS ALLOWED TO LEAVE WITH THIS VEHICLE BEFORE A RECALL THAT HAD BEEN ISSUED JUNE 26 2014 HAD BEEN REMEDIED. ( SALE AND DELIVERY OF AN UNREMEDIED RECALLED VEHICLE). UPON REPORTING TO THE SALESMAN ABOUT THE RECALL, HE AND HIS SALESMANAGER STATED TO ME THAT THERE WAS NO RECALL ON THE VEHICLE. I CHECKED WITH THE NTHSA FOUND THE RECALL AND HAD IT FIXED MAY 5, 2015. AFTER ASKING THE SALESMAN WHY MY VEHICLE HAD NOT BEEN FIXED DURING THE 6 MONTHS PRIOR TO THE SALE OF THE VEHICLE TO ME, HIS ANSWER WAS THAT THE VEHICLE HAD PREVIOUSLY SOLD IN JULY OF 2014. THE BUYER HAD THE TRUCK FOR 7 DAYS AND COULD NOT AQUIRE FINANCING AND THE VEHICLE WAS RETURNED. HENCE THIS ONE VEHICLE HAS BEEN SOLD AND ALLOWED TO LEAVE THEIR LOT TWICE WITHOUT THE RECALL BEING FIXED. THE DEALER IS NORMAN FREDE CHEVROLET IN HOUSTON TX.

THE ABOVE STATED VEHICLE WAS SOLD TO ME IN DEC. 2014, AND I WAS ALLOWED TO LEAVE WITH THE VEHICLE WITHOUT KNOWING THE VEHICLE WAS UNDER RECALL. (SALE AND DELIVERY ON AN UNREMEDIED RECALLED VEHICLE). THE RECALL FOR THIS VEHICLE HAD BEEN ISSUED JUNE 26, 2014. WHEN I ASKED THE SALESMAN ABOUT THIS RECALL, HE STATED TO ME HE HAD CKECKED WITH HIS SALESMANAGER AND THAT THERE WAS NO RECALL ON THIS VEHICLE. AFTER CHECKING WITH THE NTHSA DATABASE AND FOUND THE RECALL, I HAD IT FIXED ON MAY 5, 2015. I ASKED THE SALESMAN WHY MY VEHICLE HAD NOT BEEN FIXED DURING THE 6 MONTHS PRIOR TO THE SELL TO ME, HIS REPLY WAS THAT THE VEHICLE HAD BEEN SOLD IN JULY OF 2014 AND THAT THE BUYER HAD THE VEHICLE FOR 7 DAYS AND RETURNED IT FOR LACK OF FUNDS. THAT MEANS THEY SOLD THIS VEHICLE TWICE WHILE THE RECALL WAS UNREMEDIED.

TL* THE CONTACT OWNS A 2014 CHEVROLET SILVERADO. THE CONTACT STATED THAT WHILE DRIVING AT 85 MPH, THE SHIFT LEVER SHIFTED INDEPENDENTLY FROM HIGH TO LOW GEAR. THE VEHICLE WAS NOT DIAGNOSED OR REPAIRED. THE FAILURE RECURRED ON NUMEROUS OCCASIONS. THE MANUFACTURER WAS NOTIFIED OF THE FAILURE. THE FAILURE MILEAGE WAS 8,685.

BACKED MY TRUCK DOWN A BOAT RAMP. PUT MY TRUCK IN PARK WHILE APPLYING PARKING BRAKE TRUCK ROLLED BACK INTO WATER. WHEN PULLED OUT I NOTICED MY TRUCK WAS BACK IN PARK. I BELIEVE TRUCK JUMPED OUT OF GEAR. *TR

I WAS DRIVING DOWN THE ROAD AT ABOUT 45 MPH WHEN MY VEHICLE SUDDENLY JUMPED OUT OF GEAR INTO NEUTRAL. AFTER ABOUT 20 SECONDS IT WENT BACK INTO GEAR. *TR

I STARTED HEARING SOME TICKING. AND NO BIG DEAL THE NEXT DAY THE MOTOR JUST VIBRATED AND THEM STOPPED ACCELERATING, STARTED RATTLING. FREAKED ME OUT BIG TIME, I'VE ONLY HAD THE VEHICLE FOR ABOUT 2 MONTHS. I'M NO MECHANIC, BUT THIS AIN'T NORMAL. I FEAR THE WORST. *TR

I BEGAN TO NOTICE SEVERE VIBRATION IN THE DRIVE TRAIN AT 55 MPH, SIMILAR TO A WASHBOARD EFFECT. IN ADDITION, THE VEHICLE DOWN SHIFTED VERY HARD WHEN STOPPING. I REPORTED THIS PROBLEM TO THE DEALER ON THIS DATE AND THEY SAID IT WAS NORMAL OPERATION. IN DECEMBER, OF 2014, I TRIED PASSING A VEHICLE AND EXPERIENCED A LOUD THUMP IN THE REAR END OF THE VEHICLE, I THOUGHT THE DRIVE SHAFT WAS GOING TO FALL OUT. I TOOK THE VEHICLE TO THE DEALER AND THEY COULD NOT REPLICATE THE ISSUE. I HAVE TAKEN THE VEHICLE TO TWO DIFFERENT DEALERSHIPS A TOTAL OF 3 TIMES TO ADDRESS THIS ISSUE. THEY BOTH CLAIM THIS IS NORMAL. NOW THE VIBRATION HAS GOTTEN WORSE, IT CAN OCCUR AT 40-45, 50-55, AND 60 TO 65. I HAVE OWNED GM TRUCKS BEFORE AND THE ONLY TIME I HAD AN ISSUE LIKE THIS WAS WHEN THE DRIVE SHAFT ON A 1994 SAFARI VAN WAS OUT OF BALANCE HAD TO BE RE BALANCED. I HAVE NOTED SEVERAL OTHER COMPLAINTS FROM OTHER 2014 -15 VEHICLE OWNERS. THIS TYPE OF OPERATION HAS TO BE DAMAGING THE GEARS AND TRANSMISSION. I HAVE CALLED THE GM AREA REP AND GOT AN ATTITUDE FROM HIM. HOWEVER, I DO HAVE ANOTHER APPOINTMENT WITH THE SELLING DEALER, (3RD WITH HIM, 4TH OVER ALL) THIS WEEK. AND WAS TOLD TO CALL THE GM REP WHEN I ARRIVE.
