2016 GMC Sierra 1500 complaints

This complaint follows the same pattern for thousands of vehicles manufactured by General Motors. The specific component is the 8L90 (RPO-5MU) 8-speed transmission. The vehicle has experienced torque converter shudder since the purchase date of 06/28/2016. Numerous "attempts" via TSBs and cover-ups by General Motors has failed to alleviate the common shifting, shuddering, rough shifting, LURCHING out of control along with appurtenant damage to adjacent components and structures within the vehicle itself. The vehicle manufacturer has attempted to forestall remedy at the expense of consumers. It has knowingly violated specific requirements for merchantability of said vehicle. IF SUCH KNOWLEDGE had been in my possession prior to purchase, I would NEVER have purchased the subject vehicle. Damage to torque converter components via polluted fluid and destructive particles caused by torque converter malfunction are situated throughout the entire structure of the named Transmission itself. Valve bodies. Gears. Filters, Fluids and tolerances have all been affected by the KNOWN DEFICIENCY by the stated manufacturer: General Motors Corporation. General Motors has shown neither the desire; nor will, to effect a meaningful and reliable solution to this problem.

Experienced error code of P0307 after vehicle backfired while on highway. Check engine light and stabilitrak lights immediately turned on and vehicle was shaking violently. Immediately took vehicle to an independent shop to have it looked at. After running diagnostics, pressure tests, and bore scope. It has been determined that piston in cylinder 7 is a complete loss and has a 0 pressure reading. From talking with shop owner he said he sees this issue quite often with GM vehicles due to DOD or AFM (active fuel management) that GM has on their engines. I'm at just shy of 67k miles, out of warranty, and needing to replace the engine.

Sudden jerking while traveling at low speeds. This jerking / shuttering happens while traveling forward, reverse, and coming to a stop. Hard shifting while driving. I've never owned a 4x4 before and thought this was normal when I purchased the vehicle. After reading about this it seems like a known problem for Chevrolet, GMC, and Cadillac. Link below for exact issues going on with my truck. https://gmauthority.com/blog/2019/08/tsb-seems-to-fix-8-speed-automatic-gm-transmission-problems/

The transmission failed on my vehicle while going highway speeds. The vehicle shifted into neutral and I was force to pull onto the shoulder. The check engine light came on and would no longer drive without the vehicle being turned off and then back on. It would still repeat this problem over the next 2 miles while I traveled to an exit to get to a safe location. The vehicle was towed to the dealership and inspected. An internal problem was found and the whole transmission has to be replace at about 79000 miles.

The truck shakes on right side, it has done this in the past and was taken into the dealer for repair it worked for a few months then it was back and not it has returned again. it is to the point that if feels unsafe to drive

Brakes at low speeds and in drive ways and parking lots when stopping brakes won't work very dangerous a recall was issue but not for my truck, the vacuum pump is bad on my truck

1. Loss of Power Steering - Engine shuts down - Dashboard flickers (sometimes it turns back on) 2. Loss of Power Steering & Engine shuts off while in motion - EXTREMELY DANGEROUS (Usually happens at slower speeds when turning the steering wheel) 3. Dealer has not been able to confirm the problem 4. The dealer won't look at problems unless "it" happens in their hands because the diagnostic does not show this problem. 5. No warning before this happens. No way to force the problem to happen....it just happens usually when turning wheel at slow speeds. 6. THIS IS SO DANGEROUS.... 7. The 2015 Sierra has a recall for this problem, Mine is a 2016 8. PLEASE HELP - VERY DANGEROUS

While driving a hissing sound was heard from rear window, smoke appeared and rear window shattered. Dealer states that there was a short in the electrical system consistent with recall # N192220470 and that my vehicle does have RPO A48. My vehicle was not included in this recall due to geographical location of vehicle (Pennsylvania). This is a known potential fire risk and glass shattered into the vehicle. It should be noted that the outside temp was 60 degrees and my husband did NOT turn on defroster or open the rear window. After the smoke clear and window shattered he noticed that the defroster light was on and he shut it off manually. Had there been rear seat passengers they would have had glass on them and subjected to smoke and possible fire. God forbid a child in a rear facing child safety seat was back there, they would have been at serious risk of harm. GM has been notified and at this time is refusing to include this vehicle in their limited scope recall. I know of several others with similar stories (avail upon request), one lives in South Carolina, proving that this recall should not be limited to northern tier states. The current recall must be expanded to all 50 states asap. Lives and property are at risk.

The contact owns a 2016 GMC Sierra 1500. The contact stated while driving at 45 mph, the four-wheel drive service light illuminated on the instrument panel. As he proceeded driving down the highway, both the service stabilitrak and the no power steering, drive with caution messages appeared on the instrument panel. The contact started losing control of the steering wheel as the vehicle began to sway. The decreased engine power, drive with caution message was also displayed on the instrument panel as the contact cautiously drove the vehicle into a parking lot and restarted the vehicle without further incidence. The next day, the contact drove the vehicle to a dealer where an electrical reboot was performed and the vehicle was returned to the contact. After the vehicle was returned, the contact was driving 50 mph when the failure recurred. The contact continued driving to his destination. The contact returned the vehicle to the dealer where it remained in their possession. The manufacturer was notified of the failure and informed him that there were no recalls on the VIN. The vehicle was not yet repaired. The failure mileage was approximately 72,000. The VIN was unavailable.

Truck was purchased on 11:28:20 and had my first oil change in March. Started noticing a ticking sound coming from the motor but it was. Very faint. After a while it went away. After a few weeks later the noise started to get louder and started shaking. Took to the near mechanic and he diagnosed it with bad lifters on the passager side.. I took it to another mechanic where their replaceming all lifters for 4.8k. This truck is not too old and I shouldn’t be replacing any engine parts. It only has 100k miles and it’s a 2016.

-Engine gas consumption state 21 MPG Highway, 17 MPG Combined and 15 MPG City. When I started using this vehicle during the first weeks and months the best MPG I could get at the highway is 18.5 MPG with top tier gas such Shell & Chevron during the first 2 years and now Costco brand. Every since I bought it, the gas MPG have gone down around 0.5 MPG. The vehicle feels that it has to use more gas in order to perform. -The motor oil pump at times moves down from the 40 mark to the 20 when idle at traffic light and when it starts moving, it temporarily moves to the 60 mark. -The transmission is an 8 speed automatic. It has issues shifting to first gear, second gear and times 3rd gear. When driving at slow speeds like in traffic jams, mall parking lots or when you slow down at the traffic light and then turns green and you start accelerating again it feels harsh on gearing down and up, like someone rear ended your vehicle. -This truck has the Active Fuel Management (AFM) and it turns on even slower speeds and you feel how the engine and transmission struggle to really gear up and down. Like it never gears and tries to accelerate at a higher gear. Like in manual transmissions when you accelerate on a higher gear than at correct own it takes forever to reach the needed speed. -Even if all 8 pistons are on it feels as if I am running on a smaller engine like a V6 or V4. -The driver car seat feels that move a little like an 1/8 of an inch. -It just feels that something is wrong with

AT SLOW SPEED THE BRAKE BECOMES ROCK HARD AND CANNOT BE PUSHED IN. I HAVE RESEARCHED A RECALL # N192268490. I HAVE SEARCHED MY VEHICLE BY VIN AND IT STATES NO RECALL WHICH I DON'T UNDERSTAND. I BELIEVE IT IS SOMETHING RELATED TO THE SLOW SPEED BRAKE MODULE. I WOULD LIKE TO KNOW IF THIS IS AN ACTUAL RECALL AND WHY THIS VEHICLE IS NOT INCLUDED.

STEERING WHEEL JOLTS AGGRESSIVELY FROM THE DRIVERS HANDS. ALL ELECTRONICS SHUTDOWN, ENGINE SHUTS DOWN, STABILITRAK ERROR & TRAILER BRAKE ON DISPLAY. THESE CONDITIONS OCCUR AT ANY SPEED, GOING STRAIGHT OR TURNING. 25MPH IN CITY, DRIVING 45 MPH COUNTRY ROADS OR WHEN STATIONARY. VERY DANGEROUS!

WHILE DRIVING THE VEHICLE HOME FROM WORK, THE VEHICLE SHUT DOWN IN THE MIDDLE OF TRAFFIC ON A STREET WHILE STOPPED AT A TRAFFIC LIGHT AND WOULD NOT MOVE AFTER ATTEMPTING TO PUT THE TRUCK IN "DRIVE". I HAD TO CALL FOR AN EMERGENCY ROADSIDE SERVICE (TOW TRUCK) WHICH TOWED THE VEHICLE TO A GMC DEALERSHIP SERVICE DEPT. I WAS TOLD BY THE SERVICE TECHNICIAN THAT THE TRANSMISSION TORQUE CONVERTER HAS DISINTEGRATED AND IT WOULD COST OVER $5000 TO REPAIR. THIS VEHICLE DID NOT PROVIDE ANY WARNINGS (NO WARNING SIGNAL DISPLAYED ON THE INSTRUMENT PANEL) THAT THE TRANSMISSION NEEDED SERVICING. I HAVE OWNED THIS VEHICLE FOR 3 YEARS. THIS VEHICLE NEEDS REVIEWING FOR A RECALL.

"SERVICE BRAKE ASSIST" MESSAGE HAS CONTINUOUSLY SHOWN UP ON DASH FOR OVER A YEAR, ESPECIALLY WHILE AT LOW SPEED IN REVERSE MOST COMMONLY. VEHICLE FEELS LIKE POWER BRAKES NO LONGER FUNCTION AND VEHICLE CONTINUES TO ROLL UNLESS YOU STAND ON THE BRAKE PEDAL. THIS IS SUPPOSEDLY AFTER THE RECALL REPAIR.

WHEN DRIVING I FELT A SLIGHT SHIFT BETWEEN 1 AND 2. THAT SEEMED PRETTY NORMAL. WHILE DRIVING TO THE OCEAN BETWEEN 50-60 MPH THERE WAS NOT SHIFTING, SHARKING OR JERKING. ONCE SLOWING DOWN TO 30-40 MPH THE RPMS GO EXTREMELY HIGH TO 4 OR 5. PULLING AND JERKING THE VEHICLE. HAPPENING AROUND 20-30 MPH OR AT 40-50. THE VEHICLE WILL COME TO A STOP CAUSING TRAFFIC DISRUPTIONS AND NEAR ACCIDENTS. NO SERVICE OR CODING HAVE BEEN ABLE TO DIAGNOSE ISSUE WITH VEHICLE.

TL* THE CONTACT OWNS A 2016 GMC SIERRA 1500. THE CONTACT STATED THAT THE STEERING AND SUSPENSION EITHER LOCKED UP OR WAS VERY LOOSE WHILE DRIVING APPROXIMATELY 30 MPH. ADDITIONALLY, THE STEERING EITHER CEASED OR BECAME LOOSE. THE CONTACT CONTACTED ED BOZARTH CHEVROLET COMPANY, INC. (2001 S HAVANA ST, AURORA, CO 80247, (720) 773-5338) WHO STATED THAT A SOFTWARE UPDATE NEEDED TO BE PERFORMED ON THE VEHICLE. THE VEHICLE HAD NOT BEEN REPAIRED. THE MANUFACTURER WAS MADE AWARE OF THE FAILURE AND REFERRED THE CONTACT TO NHTSA. THE APPROXIMATE FAILURE MILEAGE WAS 56,000.

I'VE HAD MOVEMENT IN MY DRIVERS SEAT SINCE THE DAY I'VE OWNER THE TRUCK. GMC PUT IN A SHIM KIT TO ADDRESS THE PROBLEM BUT IT'S STILL ACTING UP. THEY REFUSE TO REPLACE OR REPAIR ANY FURTHER. ALSO MY TRANSMISSION HAS A HORRIBLE SHIFTING PROBLEM. WHEN IT'S COLD OUT OR AFTER THE FIRST TIME SHIFTING INTO GEAR AFTER SITTING A LONG TIME, THE TRUCK LAGS TO SHIFT INTO GEAR THEN ALL OF A SUDDEN LUNGES FORWARD OR BACKWARDS DEPENDING ON WHICH GEAR I'M IN. I'VE ALMOST RAN THROUGH MY GARAGE DOOR AND SIDE FENCE AND HAD TO SLAM ON THE BRAKES. GMC HAS LOOKED INTO THE ISSUES BUT WON'T RESOLVE THEM. THE LAST 'REPAIR' MADE WAS TO CHANGE OUT THE TRANSMISSION FLUID. THAT HAD HELPED WITH THE HARD SHIFTING WHILE DRIVING BUT THE TRUCK STILL LUNGES FORWARD OR BACKWARDS AND LAGS SHIFTING INTO GEAR. I'VE HAD TO LEARN TO DEAL WITH IT BUT ANYONE ELSE WHO WOULD DRIVE MY TRUCK COULD SERIOUSLY HURT THEMSELVES OR SOMEONE ELSE

I USED MY REMOTE START TO START MY 2016 GMC SIERRA TO WARM IT UP WHILE CLEANING THE SNOW OFF MY OTHER WINDOWS. I SMELLED SMOKE AND NOTICED MY DRIVERS SIDE BACK WINDOW COMPLETELY SHATTER BEFORE MY EYES. UPON FURTHER INVESTIGATION I SEE MANY PPL THAT HAVE REPORTED SIMILAR INCIDENTS OCCURRING IN GMC VEHICLES YEARS 14-18 SOME EVEN WITH SHARDS SHOOTING INTO THEIR VEHICLES. THIS IS COMPLETELY RIDICULOUS, AND EXTREMELY UNSAFE AND COULD SERIOUSLY INJURE SOMEONE. THE VEHICLE WAS STATIONARY AND STARTED BY REMOTE START

BRAKE ASSIST LIGHT CAME ON AND I HAD NO BRAKES WHEN I PUSHED THE PEDAL HARDER BRAKES TRIED TO LOCK UP I ALMOST WRECKED

MIPOWERED BRAKE-ASSIST SYSTEM, WHICH REDUCES THE AMOUNT OF EFFORT A DRIVER NEEDS TO EXERT TO STOP THE VEHICLE. IF THE SYSTEM FAILS, A DRIVER MAY FIND THAT THE BRAKE PEDAL TAKES MUCH MORE EFFORT TO PUSH. DRIVERS MAY ALSO FIND THAT IT TAKES MORE DISTANCE FOR THEIR VEHICLE TO STOP, WHICH COULD LEAD TO A CRASH,

I HIT A DEER ON THE HIGHWAY AND THE SEATBELTS LOCKED UP ON US AS WE HAD THEM ON, WE PULLED OFF AND TOKE OUR SEATBELTS OFF TO SEE THE DAMAGE DONE AND NOW THE SEATBELTS ARE LOCKED UP COMPLETELY AND WON'T COME LOSE TO WEAR THEM.

THE BRAKES ARE VERY HARD TO PRESS AT LOW SPEED MORE SO AFTER I HAVE PRESSED THEM A COUPLE TIMES OR MORE WHILE IN MOTION IN STOP AND GO TRAFFIC . I HAD A RECALL FOR THIS ABOUT A YEAR AGO AND TOOK IT TO THE DEALER TO HAVE IT FIXED BUT JUST STARTED EXPERIENCING THIS PROBLEM WITHIN THE LAST COUPLE OF MONTHS. VERY SCARY TO NOT HAVE POWER BRAKES ALL OF A SUDDEN! THE RECALL OBVIOUSLY DOES NOT FIX THE PROBLEM!!

UPON STARTING THE TRUCK TO WARM IT UP THE POWER SLIDING REAR WINDOW WITH DEFROSTER BURNED COMPONENTS AND THE LEFT PORTION OF THE WINDOW SHATTERED, LUCKILY AVOIDING A FIRE. IT IS JUST LIKE THE RECALL IN CANADA #N192220470 AND ALSO # N192265660. GM ALREADY ACCEPTED PARTIAL BLAME TRYING TO GIVE AN UNACCEPTABLE AMOUNT OFF THE REPAIRS.

TL* THE CONTACT OWNS A 2016 GMC SIERRA 1500. THE CONTACT STATED HE STARTED VEHICLE USING THE REMOTE START FUNCTION. WHILE DRIVING APPROXIMATELY 40 MPH, THERE WAS AN ABNORMAL ODOR OF SMOKE DETECTED INSIDE THE CABIN OF THE VEHICLE. THE REAR DRIVER'S SIDE WINDOW SHATTERED WITHOUT WARNING OR IMPACT. THE VEHICLE WAS TAKEN TO JOSEPH BUICK GMC (8700 COLERAIN AVE, CINCINNATI, OH 45251, (513) 741-1000) AND THE CONTACT WAS INFORMED TO SCHEDULE AN APPOINTMENT. THE VEHICLE WAS NOT DIAGNOSED NOR REPAIRED. THE MANUFACTURER WAS CONTACTED AND INFORMED OF THE FAILURE. THE CONTACT WAS REFERRED TO THE LOCAL DEALER FOR ASSISTANCE. THE FAILURE MILEAGE WAS 76,000.

DRIVE TRUCK TO THE STORE GOT BACK HOME WHEN I SHUT MY DOOR STATIONARY I HEARD A LOUD SHATTERING SOUND IT TURNED OUT TO BE MY REAR WINDOW LOOKED ONLINE IT LOOKS LIKE THIS IS BECOMING A COMMON OCCURANCE CALLED GMC THEY SAID IT IS ALL HE SAY SHE SAY AND NO RECALL IS AVAILABLE, IF THERE HAD BEEN A PERSON IN THE BACK SEAT THEY WOULD HAVE POSSIBLY BEEN INJURED WITH THE GLASS EXPLODING

WHEN TRAVELING BACKWARDS AT LOW SPEED IT APPEARS THAT MY ABS IS TRYING TO TURN ON. THE LIGHT DOESN'T COME ON, BUT IT IS VERY HARD TO STOP. IT WILL DO IT GOING FORWARD, BUT MAINLY BACKWARDS.

TL* THE CONTACT OWNS A 2016 GMC SIERRA 1500. THE CONTACT STATED THAT WHILE HER HUSBAND WAS DRIVING AT 45 MPH HE SUDDENLY SAW SMOKE COMING FROM UNDERNEATH THE HOOD.THE HUSBAND PULLED THE VEHICLE OVER AND GOT OUT OF THE VEHICLE QUICKLY AND WATCHED AS THE VEHICLE WAS ENGULFED IN FLAMES. THE ENTIRE VEHICLE WAS DESTROYED BY THE FIRE . THERE WERE NO INJURIES AND A POLICE REPORT WAS NOT FILED. THE WRECKAGE WAS TOWED TO AN IMPOUND YARD. THE CONTACT RETRIEVED A WRECKAGE AND TOWED IT TO A PRIVATE RESIDENCE. THE DEALER AND MANUFACTURER HAD NOT BEEN CONTACTED YET. THE FAILURE MILEAGE WAS 50,000.

WHILE MOVING SLOWLY IN TRAFFIC (~5MPH) WHEN APPLYING LIGHT BRAKE PRESSURE IT FELT LIKE ABS WAS KICKING IN AND THERE WAS NO BRAKING. THIS HAPPENED TWICE BEFORE THE BRAKES RESUMED NORMAL OPERATION. HAPPENED AGAIN AS I WAS BACKING OUT OF MY DRIVEWAY. THE RECALL REGARDING THE REPROGRAMMING OF ECBM (N192268490) WAS DONE ALREADY.

ON AVERAGE, ABOUT EVERY 3RD TIME I DRIVE THIS TRUCK, BUT ALMOST EVERY TIME IF IT'S WET OR COLD, I GET A WARNING THAT THERE IS A MECHANICAL ISSUE WITH MY AIRBAGS. I DON'T KNOW WHICH ONE, OR WHAT PART OF THE SYSTEM IS FAILING, BUT THE AIRBAG WARNING LIGHT WILL REMAIN ON THE ENTIRE TIME I'M DRIVING AND I GET NOTICES FROM ONSTAR THAT IT REQUIRES IMMEDIATE ATTENTION. IT'S HAPPENED TOO MANY TIMES FOR ME TO COUNT. THE FIRST TIME IT HAPPENED (OVER A YEAR AGO), I TOOK IT TO THE DEALERSHIP REGARDING THE ISSUE, THEY THOUGHT IT WAS LIKELY ELECTRICAL AND COULD BE FIXED WITH A $1000 REPAIR.

SMELLED ELECTRICAL BURNING AND THEN SECONDS LATER THE DRIVER SIDE OF MY REAR WINDOW EXPLODED INTO PIECES WITH A LOUD BANG.

BRAKES FAIL. WILL NOT ALLOW VEHICLE TO COME TO A COMPLETE STOP WHEN GOING FORWARD OR IN REVERSE. WHEN ACCELERATING VEHICLE VIOLENTLY SHAKES. THIS HAPPENS AT ANY SPEED ABOVE 20MPH.

AT LOW SPEEDS THE BRAKES GET VERY HARD TO PRESS AND THE TRUCK TAKES LONGER TO STOP. THE SERVICE BRAKE LIGHT HAS CAME ON SOMETIMES WHEN THIS OCCURS. I'VE SEEN AN OPEN RECALL FOR THE EXACT PROBLEM WITH MY TRUCK, BUT WHEN I ENTER MY VIN IT SAYS MY TRUCK IS NOT PART OF THE RECALLED VEHICLES. PLEASE HELP ME

BRAKES BECAME SPONGY WHILE HAULING A BOAT ALMOST CRASHED WHILE COMING TO A STOP AT A TRAFFIC LIGHT BRAKES WERE HARD TO COMPRESS. VEHICLE DIDN'T WANT TO STOP IMMEDIATELY... HAD TO USE THE EMERGENCY BRAKE TO COME TO A COMPLETE STOP. RIGHT AFTER THE SERVICE WARNING SIGN CAME ON SHOWING ( BRAKE ASSIST SERVICE)

AT STARTUP, IF YOU SHIFT FROM PARK TO DRIVE OR REVERSE, THE BRAKE PEDAL STIFFENS AND IT IS HARD TO STOP. IF YOU ARE ABLE TO SPEED UP OVER A CERTAIN SPEED, SAY 15 TO 20 MPH, THEN THE TRUCK BRAKES FINE. I HAVE TAKEN IT TO THE DEALER AND THEY REPLACED THE BRAKE BOOSTER PUMP, BUT IT STARTED DOING IT AGAIN WITHIN A DAY OR TWO.

TL* THE CONTACT OWNS A 2016 GMC SIERRA 1500. THE CONTACT STATED THAT WHILE REVERSING, THE STEERING WHEEL SEIZED WITH THE CHECK ENGINE WARNING LIGHT AND PARKING ASSIST WARNING LIGHT ILLUMINATED. THE CONTACT STATED THAT THE VEHICLE NEEDED TO BE SHIFTED TO PARK AND RESTARTED FOR THE VEHICLE TO OPERATE AS INTENDED. THE FAILURE RECURRED MULTIPLE TIMES. THE DEALER WAS NOT CONTACTED. THE VEHICLE WAS NOT REPAIRED. THE MANUFACTURER WAS NOTIFIED OF THE FAILURE. THE APPROXIMATE FAILURE MILEAGE WAS 42,000.

I BOUGHT MY GMC BRAND NEW WITH 25 MILES ON IT. THE FIRST TIME I HAD A BRAKING ISSUE WAS PULLING INTO WORK. I HAD ROUGHLY 56,500 MILES ON THE TRUCK AT THIS POINT. I WAS COMING IN CAUTIOUSLY DUE TO A HEAVY TRAFFIC AREA. AS I PULLED INTO MY PARKING SPOT I ENGAGED THE BRAKES. THE PEDAL WAS SOFTER THAN USUAL. I PUSHED DOWN HARDER AND I CAME TO A SLOW ROLLING STOP. I THOUGHT I WAS GOING TO HIT THE BUILDING. I LET THE TRUCK SIT/RUN 5MIN, (I AM MECHANICALLY INCLINED, WAS IN AUTOMOTIVE TECH COURSES FOR 3 YEARS) I CHECKED THE BRAKES/BRAKE FLUID AND TRIED THE BRAKES IN THE REVERSE GEAR. LET THE TRUCK CREEP BACK AND TESTED THE BRAKES. THEY WERE NORMAL AGAIN. I CALLED THE DEALERSHIP AND MADE AN APPOINTMENT.(UPLOADED SERVICE PAPERWORK). DEALER SAID THERE WASN'T A RECALL AT THIS TIME BUT WANTED ME TO DO A BRAKE FLUID FLUSH BUT I WASN'T IN WARRANTY ANYMORE SO IT WAS GOING TO COST ME OVER 100+ DOLLARS. THAT'S WHY I REFUSED THE SERVICE. THE WINTER MONTHS GO BY AND MY BRAKES ARE FINE. THE SECOND TIME I NOTICED THIS ISSUE, WAS SPRING TIME THE FOLLOWING YEAR, I WAS PUTTING MY PONTOON BOAT IN THE WATER. BACKING INTO THE WATER I WENT TO STOP AND MY TRUCK KEPT ROLLING INTO THE WATER. I ENGAGED THE EMERGENCY FOOT BRAKE. I PULLED FORWARD AND THE BRAKES WERE BACK TO NORMAL. I TEST DROVE THE TRUCK IN THE EMPTY PARKING LOT THIS TIME, SEE IF IT WOULD HAPPEN AGAIN. CALLED THE DEALERSHIP AND ASKED IF THERE WAS A RECALL AND THEY SAID NO. BRAKES ARE BACK TO NORMAL AT THIS POINT. FINALLY THAT YEAR I RECEIVED A

TL* THE CONTACT OWNS A 2016 GMC SIERRA 1500. THE CONTACT STATED WHILE DEPRESSING THE BRAKE PEDAL TO STOP THE VEHICLE, THE BRAKE PEDAL FELT VERY HARD CAUSING THE BRAKING DISTANCE TO BE EXTENDED. THE FRONT PASSENGER'S SIDE BRAKE ROTOR WAS DAMAGED. THE VEHCILE WAS TAKEN TO THE LOCAL DEALER RALLY CHEVROLET LOCATED AT 39012 CARRIAGE WAY, PALMDALE, CA 93551, WHO REPROGRAMMED THE BRAKING SYSTEM MODULE HOWEVER, THE FAILURE PERSISTED. THE MANUFACTURER WAS NOTIFIED OF THE FAILURE BUT, OFFERED NO ASSISTANCE. THE FAILURE MILEAGE WAS 46,000. THE VIN WAS NOT AVAILABLE.

AT VERY LOW SPEEDS SUCH AS BACKING UP OR PARKING THE BRAKE PEDAL WILL NOT INDICATE PRESSURE AS IF THE TRUCK WAS SHUT OFF. WHILE BACKING UP OR PARKING YOU MAY HIT ANOTHER VEHICLE. THIS HAS HAPPENED MORE THAN A FEW TIMES AND WE RETURNED THE TRUCK TO HAVE THIS CONDITION CORRECTED. GMC DEALER SAID IT WAS A RECALLED FOR THAT ISSUE AND IT WAS CORRECTED BUT IT SEEMS TO HAVE RETURNED.

ANTENNA HAS CRACKED SEAL AND MOISTURE GOT IN AND SHORTED OUT NAVIGATION & ON STAR. BULLETIN FOR PROBLEM WITH SAME YEAR, MAKE & MODEL BUT NOT VIN. REFUSE TO FIX. CLAIM ITS NOT A SAFETY ISSUE. NOT A GREAT STATEMENT TO MAKE TO A FIRST RESPONDER WHO HAS SAVED LIVES BY SOMEONE USING ON STAR. NO MORE GM'S FOR THIS FAMILY AND WE HAVE 3 CURRENTLY AND WAS LOOKING TO REPLACE ONE NEXT MONTH. NOT A FORD PERSON SO LOOKS LIKE A RAM IN OUR FUTURE. NOT A SAFETY ISSUE .... REALLY GM !!!!!!!!

WHILE BACKING OUT OF A PARKING SPACE, I LOST THE ABILITY TO DEPRESS THE BRAKE PEDAL. IT WAS STUCK MOMENTARILY. IT ONLY MOVE AFTER I STOMPED ON IT TWICE. AFTERWARD, THE VEHICLE WOULD STOP, BUT THE BRAKES WERE SQUISHY AND VERY EASILY OVER APPLIED. SERVICE BRAKE CONTROL MESSAGE IS NOW ON THE DASH. TRUCK HAS 42000 MILES.

THERE IS A SMALL PIN HOLE IN THE RADIATOR THAT THE DEALERSHIP ADVISED WAS CREATED BECAUSE OF A PROBLEM WITH THE THERMOSTAT. APPARENTLY GM IS AWARE OF THE PROBLEM AND WILL FIX IT IF IT'S PRIOR TO 60,000 MILES. I AM SEVERAL THOUSAND OVER NOW AND THEY REFUSE TO COVER ANY OF THE 1100.00 BILL TO REPAIR

DRIVING ON THE HIGHWAY BRAKES LOCKED UP BREAK PEDAL SUPER HARD TO PRESS

WHEN DRIVING AND THE TRUCK SHIFTS GEAR IN 30MPH IT STARTS TO VIBRATE OR JERK AND THE RPM JUST BOUNCES UP AND DOWN SAME THING HAPPENS IN 40 MPH AND 50 MPH AS WELL I HAVE TAKEN IT TO THE DEALER SHIP IN FALL OF 2019 AND ALL THEY DID WAS A TRANS FLUID FLUSH. AND WORKED FINE FOR A BIT NOW THE TRUCK STARTED TO DO THE SAME THIN IN THE BEGINING OF JULY 2020 AND TOOK IT AGAIN TO THE DEALER AND THEY WANTED TO DO THE SAME THING THEY DID IN 2019 DO THE TRANS FLUID FLUSH. NOT THIS TIME MY EXTENDED WARRANTY WAS NOT COVERING IT BECAUSE THE SAID IT WAS A MAINTENANCE WHICH IS NOT CORRECT BECAUSE GM KNOW IT WAS AN ISSUE AND I HAD ALREADY DONE THE FLUCH BACK IN 2019 AND THE DEALER DIDNT WANT TO COVER IT ETHIER I WOULD HAVE TO PAY ALMOST 500 TO GET IT DONE. I DONT KNOW HAT ELSE TO DO

STARTED TRUCK. NO RADIO, BACKUP CAMERA, NOTHING ON SCREEN. ALSO NO BLINKER SOUND. ALL CAME BACK ON AFTER DISCONNECTING AND RECONNECTING NEGATIVE BATTERY CABLE. BEFORE THIS HAPPENED, THE RADIO HAD RESET ITSELF 4 OTHER TIMES AND I HAD TO RESET CLOCK AND RADIO STATIONS. GMC HAS HAD THIS PROBLEM WITH OTHER VEHICLES.

AIR CONDITIONER STOPPED WORKING AT 70,000 MILES

[XXX] I WAS IN THE DESERT AND THE STEERING WHEEL STOPPED WORKING, I WAS ALONE WITHOUT WATER, UNDER STRESS I CALLED GM ROAD ASSISTANCE AND EMERGENCY TO HELP ME AND THANKS TO GOD THEY CAME AFTER 6 HOURS.

WHILE MAKING TURNS THE VEHICLE INTERMITTENTLY STALLS, LOSING ALL CONTROL OF STEERING AND ELECTRICAL COMPONENTS. WHEN IT STALLS THERE IS NO STEERING CONTROL WHATSOEVER AND THE VEHICLE DOES HAVE BRAKES, BUT SLOW TO REACT.. RESTART THE VEHICLE AND THE COMPUTER SYSTEM SLOWLY RESETS. THIS HAS HAPPENED 5 TIMES IN THE LAST2 DAYS. TAKING THE VEHICLE TO THE DEALERSHIP AS SOON AS THEY HAVE AN OPENING.

THE VEHICLE SHAKES AT HIGH SPEEDS OF 40 MPH AND HIGHER.
