2014 Chevrolet Silverado 1500 Power Train

WHILE DRIVING THE TRUCK STARTED MAKING A WEIRD NOISE AND THEN WOULD ALMOST FEEL LIKE U RAN OVER RUMBLE STRIPS. WITHIN A COUPLE WEEKS THE TRUCK WILL NOW NO LONGER SWITCH GEARS. THERE ARE SHAVINGS IN TRANNY FLUID. ALMOST HAD AN ACCIDENT BECAUSE THE TRUCK JUST WOULDN'T SHIFT OR GO WHILE ON THE INTERSTATE. CHEVY HAS PUT FAULTY TORQUE CONVERTERS IN THESE TRUCKS AND THEY NEED TO BE HELD RESPONSIBLE FOR FIXING THIS PROBLEM. THERE ARE THOUSANDS OF OTHER PEOPLE THAT HAVE THE SAME EXACT THING HAPPEN TO THEM. FAILURE WAS AT ONLY 120,000 MILES AND OUR TRUCK IS VERY WELL TAKEN CARE OF, MAINTENANCE DONE, AND WAS NEVER EVER DROVE HARD.

14192A TRANSFER CASE SHIFTS OUT OF GEAR WHILE DRIVING, CAUSING LOSS OF POWER, THAT COULD RESULT IN A CRASH.

I BOUGHT MY 2014 SILVERADO NEW . AFTER 10,000 MILES I COULD HEAR SOMETHING IN THE DRIVETRAIN BETWEEN 2ND AND 3 RD GEAR MAKE A MOANING SOUND . BROUGHT IT TO THE DEALERSHIP AND COULDN'T FIND ANYTHING . THIS WENT ON UNTIL 141,000 MILES AND THE TRANSMISSION CAME OUT . HAD IT REBUILT FOR $ 3,700.00 AND WAS TOLD THE TORQUE CONVERTER CAUSED THE PROBLEM . NOW I'M AT 181,000 AND WE ARE HOPING IT'S THE TCM INSIDE THE TRANSMISSION BUT IF NOT WHO KNOWS WHAT THIS WILL COST . I THINK GM SHOULD BE RESPONSIBLE FOR DEFECTIVE TORQUE CONVERTERS AS I HAVE READ MORE CUSTOMERS HAVE HAD THE SAME PROBLEM . IT WOULD BE NICE TO SEE SOME KIND OF REIMBURSEMENT . I LOVE MY TRUCK AND HAVE OWNED NOTHING BUT GM VEHICLES BUT THIS SHOULD NOT HAPPEN TWICE .

TL* THE CONTACT OWNS A 2014 CHEVROLET SILVERADO 1500. WHILE DRIVING OVER 50 MPH, THE VEHICLE SHOOK AND VIBRATED. THE VEHICLE WAS TAKEN TO AN INDEPENDENT MECHANIC WHO DIAGNOSED THAT THE TRANSMISSION TORQUE CONVERTER WAS FAULTY. THE TRANSMISSION WAS REBUILT, BUT THE FAILURE RECURRED 99,000 MILES LATER. THE VEHICLE WAS TAKEN TO H&N CHEVROLET (713 GRAND AVE, SPENCER, IA) WHERE IT WAS DIAGNOSED THAT THE TORQUE CONVERTER FAILED AGAIN. THE VEHICLE WAS REPAIRED. THE MANUFACTURER WAS NOTIFIED AND DID NOT ASSIST. THE FAILURE MILEAGE WAS 145,000. *BF *TR

THERE ARE 2 CONSCERNS I HAVE THERE IS A VIBRATION SO BAD IT WILL SPILLL A COFFEE IN THE CUP HOLDERS WHEN I AM ON THE HIGHWAY AT CRUISING SPEED AND PASSING SPEED UP TO 80 MPH AND MY SECOND ISSUE WILL HAPPEN DURING CITY DRIVING WHERE I WILL STEP ON THE GAS AND THE TRUCK LUNGES FORWARD MAKING ME HIT THE BRAKES SO I DON'T HIT ANOTHER CAR I HAVE HAD MY TIRES BALANCED AND HAD THE TRUCK IN THE SHOP MULTIPLE TIMES AND GOT DIFFERENT TIRES TO TRY AND FIX THE VIBRATION AND NOTHING WORKED AND I'VE THAD THE TRUCK AT THE DEALERSHIP FOR THE TRANSMISSION ISSUE BUT THEY SAID 'IT'S NORMAL'

2014 CHEVROLET SILVERADO LTZ CREW CAB TRANSMISSION FLUID WAS SERVICED IN 2015 AT 48,900 MILES. STILL EXPERIENCED HARD DOWN SHIFT AND TOLD BY THE DEALER THIS IS BECAUSE ITS A TRUCK. AT 100,763 MILES THE TRANSMISSION BEGINS CAVITATING, LOSS OF POWER WHILE TRAVELING AND WITH LOUD INTERMITTING SOUNDS OF METAL ON METAL. GOT THE TRUCK IN FOR LOCAL TRANSMISSION SERVICE AND THE SERVICE MANAGER SAID THE TRANSMISSION FLUID WAS BURNT AND LITTERED WITH HEAVY METAL FRAGMENTS FROM THE TRANSMISSION GEARS. OTHER LOCAL (FRIENDS) OF 2014 TRUCK OWNERS HAVE REPORTED THIS CONDITION WHICH ALL RESULTED IN A TRANSMISSION REBUILD WHICH IS $4,000 FOR THIS VEHICLE. THE STRANGE PROBLEM IS THEY ARE FAILING AT 100K MILES AND THE DEALER HAS BEEN SENT SERVICE ADVISORIES TO NOT WARRANTY ANY POWERTRAINS AFTER 100K MILES EVEN IF THE DATE IS STILL EFFECTIVE. THIS TRUCK WAS IN MOTION WHEN THE CAVITATION BEGAN AND SHORTLY AFTER (100 MILES OR SO) BEGAN METAL ON METAL SOUNDS AND LOUD CLACKING FORM THE TRANSMISSION AREA UNDER THE TRUCK. IF YOU NEED ANY FURTHER INFORMATION TO LOOK INTO THIS DON'T HESITATE TO CONTACT ME AT YOUR CONVENIENCE. JUST A QUICK BACKGROUND, I AM A LONG TIME CHEVROLET OWNER AND HAVE A 1998 K 1500 AND HAVE REPLACED THE ENGINE AND REPLACED TWO TRANSMISSIONS SO I KNOW IT DOESN'T LAST FOREVER BUT I WOULD HOPE CHEVROLET WANTS TO KNOW THIS IS HAPPENING IN THEIR PREMIUM LINE UP OF TRUCKS. I WOULD ONLY HOPE THE POWER TRAIN WOULD LAST LONGER THAN 100K MILES. THANK YOU FOR YOUR TIME!

INCIDENT OCCURRED ON MAY 27TH, 2018. AT 65 MPH (INTERSTATE) GOING ON A DOWNHILL GRADE OF APPROXIMATELY 6%, TOWING AN APPROXIMATE 2500 LB TRAILER WITH WET ROADS TO SLOW THE TRUCK DOWN APPLIED BRAKES LIGHTLY, THE TRANSMISSION UPSHIFTED (HIGHER RPM), APPLIED BRAKES AGAIN, UPSHIFTED AGAIN, DID A THIRD TIME, UPSHIFTED AGAIN (NOW AT 4000 RPM). HAD TO TAP THE GAS TO GET THE TRUCK TO DOWNSHIFT. TRANSMISSION WAS SET IN DRIVE, NOT MANUAL MODE. THIS IS A REPEATABLE CONDITION; IT DOES NOT MATTER IF TRAILER MODE ON THE TRANSMISSION IS SELECTED OR NOT. LESS DOWNGRADES (APPROXIMATELY 3% OR LESS) DO NOT SEEM TO CAUSE THE ISSUE. TRANSMISSION PROGRAMMING SEEMS TO HAVE AN ERROR. THIS IS HIGHLY UNDESIRABLE AND COULD LEAD EASILY TO AN ACCIDENT.

WAS PULLING OUT OF MY DRIVEWAY WHEN THE TRANSMISSION SLIPPED AND CAR HAD TO SLAM ON ITS BRAKES SO IT WOULDN'T HIT ME. THEN IT WAS SLUGGISH AND SLIPPING ON MY 30 MINUTE DRIVE TO WORK ON INTERSTATE 81. ON THE WAY HOME IT STARTED TO GET WORSE AND MAKING AN AWFUL HUMMING SOUND OUT OF THE TRANSMISSION. I'VE RESEARCHED THIS PROBLEM AND EVERYONE IS HAVING THE SAME PROBLEM WITH GMC AND CHEVY 1500 TRUCKS FROM 2014 TO 2017. I CHECK THE FLUIDS EVERY WEEK AND THERE ARE ALWAYS GOOD. IT JUST SEEMS THERE SHOULD BE A RECALL IF EVERYONE IS HAVING THE SAME PROBLEM. THANK YOU.

TRANSMISSION ISSUES: SURGES FORWARD AND SHIFTING TOO SOON LOUD CLUNKS WHEN IT SHIFTS UP AND DOWN LOWER GEARS VIBRATION WHEN COASTING TO A STOP DIFFICULTY/HESITATION ON SHIFTING PROPERLY ON ACCELERATION LOUD CLUNKING AT DOWNSHIFT FROM 3RD TO 2ND GEAR AND VISE VERSA AND ALSO A CLUNK SHIFT WHEN THE VEHICLE APPROACHES A COMPLETE STOP. THE DOWNSHIFT IS SO HARD THAT IT IS A SAFETY CONCERN. THERE IS TONS OF COMPLAINTS ON THE INTERNET CLAIMING THAT A PLATE ON THE 2ND GEAR HAS TO MUCH OF A GAP. IT'S A MANUFACTURE DEFECT, GM SERVICE BULLETIN: #PIP5175B AND REFERS TO MEXICAN SOURCED TRANSMISSIONS THAT WERE BUILT WITH THE STATOR SUPPORT BOLTS NOT BEING PROPERLY TORQUED, LEADING TO VARIOUS CONCERNS, THE FIRST OF WHICH TO SHOW UP IS USUALLY THE 1-2 SHIFT FLARE/SLIP. THE KICK IS HARD ENOUGH WHEN IT SHIFTS THAT YOU FEEL LIKE YOUR GETTING REAR ENDED FROM 3RD TO 2ND. ALSO YOU THINK YOUR TRANSMISSION WILL DROP OUT IT GOES INTO GEAR SO HARD.

AFTER A STATE INSPECTION OF MY 2014 CHEVY SILVERADO, I WAS TOLD THAT THE TRANSMISSION COOLING LINES WERE LEAKING AND NEEDED TO BE REPLACED. THE TRANSMISSION LINES HAD FAILED WHERE THE TWO PIECES ARE CRIMPED TOGETHER CAUSING THE LEAK.

THE RIGHT REAR AXLE SEAL WAS REPLACED BY THE DEALER DUE TO LEAKING AT 16K MILES. VEHICLE NOW HAS 44K MILES AND THE LEAK IS BACK. THIS LEAK ALLOWS REAR AXLE OIL TO POTENTIALLY CONTAMINATE THE BRAKE PADS ON THAT WHEEL IF LEFT UNNOTICED LONG ENOUGH, WHICH COULD LEAD TO HINDERED BRAKING POWER ON THE WHEEL.

VEHICLE EXHIBITS VIBRATION AT SPEEDS OF 75 MPH +. VIBRATION IS COMING FROM REAR OF VEHICLE, SUCH AS REAR AXLE. VEHICLE STARTED VIBRATING AT APPROX 30K MILES. VEHICLE IS CURRENTLY AT 44K. NO VIBRATION IN THE STEERING WHEEL. VEHICLE IS SMOOTH BELOW THE THRESHOLD SPEED NOTED ABOVE.

SHORTLY AFTER GETTING MY TRUCK, I STARTED NOTICING A VIBRATION THAT APPEARED AT CERTAIN SPEEDS. I TOOK IT TO THE TIRE SHOP AND HAD THEM COMPUTER BALANCE, ONLY TO FIND THAT THEY WERE IN BALANCE. CALLED THE DEALER WHERE IT WAS PURCHASED, AND THEY HAD NOTHING TO ADD.NOW I AM HEARING THAT MANY OWNERS OF THIS MODEL ARE HAVING THE SAME VIBRATION. NOW I HAVE RECEIVED A LETTER FROM A GROUP OF ATTORNEYS THAT SAY THAT THEY ARE REPRESENTING THE TRUCK OWNERS WITH THIS PROBLEM. I REALLY DO NOT WANT TO GET INTO SOME LEGAL THING. BUT WANT THE VIBRATION TO GO AWAY.

AT 113,000 MOSTLY HIGHWAY MILES, TRUCK STARTED SHIMMERING WHEN A LOAD WAS PLACED ON IT, LIKE GOING UP HILLS. WAS TOLD AT CHEVY DEALER IT WAS TRANSMISSION. MY WARRANTY WAS UP TILL 100K WHICH WAS 2.5 MONTHS BEFORE THIS PROBLEM. I FLUSHED TRANSMISSION EVERY 30K (WAY EARLY) AND LOCAL DEALER SAID TRANSMISSION SHOULD NEVER HAVE GONE LIKE THAT. GM IS NOT WANTING TO HELP AT ALL ON A 48K COST TRUCK AND I HAD TO PAY 5150.00 TO REPLACE TRANSMISSION. PLUS OUT OF TOWN "BEING STUCK" COSTS TOO.

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.

VERY NOTICEABLE VIBRATION AT 25 MPH AND AGAIN AT 45 MPH. ONLY SEEMS TO AFFECT VEHICLE IN 4 CYLINDER MODE. LOTS OF INTERNET RESEARCH HAS FOUND THIS TO BE A RECURRING PROBLEM WITH MANY CHEVY SILVERADO 1500'S AS IT IS IN MINE. I HAVE CONTACTED GM WITH A COMPLAINT AND THEY HAVE GIVEN ME CASE # 8-2286316021. THERE SEEMS TO BE NO FIX ESTABLISHED AS OF YET. BUT, MY CONCERN IS WHEN DRIVING ON SNOW, ICE OR WET ROADS, THE VIBRATION COULD CAUSE A SERIOUS ISSUE WITH TRACTION. IF IT VIBRATES WHILE ON SLIPPERY ROAD CONDITIONS THEN THE TRACTION IS REDUCED CAUSING A SAFETY CONCERN.

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!!!!!!!!!!!!
