Air bags, side/window, curtain, inflatorSep 24, 2026
General Motors, LLC (GM) is recalling certain 2016 Chevrolet Silverado 2500/3500, GMC Sierra 2500/3500 vehicles, and 2016-2017 Chevrolet Silverado 1500 and GMC Sierra 1500 vehicles. The left-side or right-side roof rail air bag (RRAB) inflator end cap may detach from the inflator or the inflator sidewall may rupture.
A detached end cap or inflator rupture can allow compressed gas to escape and project the end cap or fragments of the inflator into the vehicle, increasing the risk of injury.
Dealers will replace both RRAB modules, free of charge. Owner notification letters are expected to be mailed November 9, 2026. Owners may contact GMC customer service at 1-888-988-7267 or Chevrolet customer service at 1-800-222-1020. GM's number for this recall is N262569920.

Service brakes, hydraulic, antilock/traction control/electronic limited slip, wheel speed sensor/tone ringOct 24, 2019
General Motors LLC (GM) is recalling certain 2015-2020 Chevrolet Suburban, Tahoe, and GMC Yukon, and 2014-2018 Chevrolet Silverado 1500 and GMC Sierra 1500 vehicles equipped with a 5.3-liter engine, a 3.08-ratio rear axle and four-wheel drive. If a wheel-speed sensor fails, while the vehicle is traveling between 41 and 60 mph in four-wheel or automatic mode, the Electronic-Brake Control Module (EBCM) software may activate the driveline-protection system.
Unintended activation of the driveline-protection system will cause unintended braking on the wheel on the opposite side of the failed sensor, causing the vehicle to pull to one side unexpectedly, increasing the risk of a crash.
GM will notify owners, and dealers will reprogram the EBCM, free of charge. The recall began December 11, 2019. Owners may contact Chevrolet customer service at 1-800-630-2438 or GMC customer service at 1-800-462-8782. GM's number for this recall is N192261050.

General Motors LLC (GM) is recalling certain 2015-2017 Cadillac Escalade, 2014-2018 Chevrolet Silverado, GMC Sierra, 2015-2018 Chevrolet Suburban, Tahoe, GMC Yukon vehicles. The amount of vacuum created by the vacuum pump may decrease over time.
As the vacuum level drops, the brake assist decreases, increasing braking effort, extending the distance required to stop the vehicle, thereby increasing the risk of a crash.
GM will notify owners, and dealers will reprogram the Electronic Brake Control Module, free of charge. The recall began October 8, 2019. Owners may contact Chevrolet customer service at 1-800-630-2438, Cadillac customer service at 1-800-458-8006 or GMC customer service at 1-800-462-8782. GM's number for this recall is N192268490.

Child seat, tether, connector/clipAug 3, 2017
General Motors LLC (GM) is recalling certain 2017 Chevrolet Silverado 1500, and GMC Sierra 1500 trucks.

As such, these vehicles fail to comply with the requirements of Federal Motor Vehicle Safety Standard (FMVSS) number 225, "Child Restraint Anchorage Systems."
If the instructions are missing from the owner's manual, the child seat may be installed incorrectly and not be properly secured, increasing the risk of injury in a crash.
GM will notify owners, and dealers will provide a corrected insert for the owners manual, free of charge. The recall began on September 25, 2017. Owners may contact GM customer service at 1-800-222-1020 (Chevrolet), or 1-800-462-8782 (GMC). GM's number for this recall is 17307.

While being previously remedied for recall 16V-651, the affected vehicles may not have received the complete software update necessary to remedy the recall condition. Without the update, certain driving conditions may cause the air bag sensing and diagnostic module (SDM) software to activate a diagnostic test. During this test, deployment of the frontal air bags and the seat belt pretensioners would not occur in the event of a crash.
A failure of the front air bags or seat belt pretensioners to deploy in the event of a crash necessitating deployment increases the risk of injury to the driver and front passenger.
GM will notify owners, and dealers will reflash the SDM software. Vehicles that have had a previous air bag deployment will have the SDM replaced. These repairs will be performed free of charge. The recall began on August 4, 2017.

THE SAME ISSUE AS GM SERVICE BULLETIN PI1513F (RADIATOR LEAK) HAS HAPPENED ON MY 2017 GMC SIERRA. THIS SERVICE BULLETIN CURRENTLY COVERS 2014 - 2016 MODELS AND NEEDS TO BE EXTENDED TO COVER 2017 MODELS (AND POSSIBLY 2018). THIS ISSUE IS A RADIATOR THAT LEAKS ON THE PASSENGER OR DRIVERS SIDE ON THE WALL BETWEEN THE COOLING FINS AND THE END OF THE RADIATOR. *TR
Power train, Service brakes, Engine, May 21, 2020
OUR TRUCK IS LESS THAN THREE YEARS OLD WITH APPROXIMATELY 69000 MILES. THE TRANSMISSION JUST STARTED SLIPPING OUT OF THE BLUE WHILE DRIVING THRU A NEIGHBORHOOD. WHILE IN DRIVE IT WOULD MOVE BUT ONCE ACCELERATING IT WOULD REV UP AND NOT CHANGE GEARS. THIS HAPPENED WITHOUT WARNING, WITHOUT AN ENGINE OR WARNING LIGHT. WE DO ALL THE NECESSARY REGULAR MAINTENANCE. IN ADDITION TWO YEARS AGO WHILE THE TRUCK WAS A YEAR OLD, THE BRAKES WENT OUT WHILE DRIVING ON THE INTERSTATE. I GUESS IT WAS THE BRAKE VACUUM PUMP OR WHATEVER THAT DIDN'T ALLOW THE BRAKE PEDDLE TO BE PRESSED WHICH PROVIDED ME WITH NO BRAKES. AGAIN WITH ABSOLUTELY NO WARNING! THIS LATER BECAME RECALL ISSUE BUT NOT BEFORE IT HAD ALREADY HAPPENED TO ME! I UNDERSTAND THERE IS A CLASS ACTION LAW SUIT AGAINST GMC FOR TRANSMISSION PROBLEMS AND I WOULD CONSIDER BEING A PART OF THIS. THIS IS A 50;000$ AND RELATIVELY NEW TRUCK, THIS IS UNACCEPTABLE! THE DEALER NOW WANTS OVER 4000$ FOR REPAIRS. *TR
Power train, Apr 13, 2020
I HAVE BEEN EXPERIENCING THE HARD UP SHIFT AND DOWN SHIFT PROBLEMS THAT HAS AFFECTED ALMOST ALL GMC SIERRA PICKUPS WITH THE GM 8L90 AND 8L45 TRANSMISSIONS SINCE 2015. THE DEALERSHIP TOLD ME THAT THERE WAS NO REPAIR FOR THE PROBLEM AND RESET THE TRANSMISSION COMPUTER ON 5 SEPARATE OCCASIONS WHICH DID ABSOLUTELY NOTHING TO REMEDY THE PROBLEM. MY VEHICLE IS NOW OUT OF WARRANTY AND THE DEALERSHIP WANTS TO CHARGE ME $2800 TO REPLACE THE VALVE BODY IN THE TRANSMISSION. WHAT IS THE NHTSA GOING TO DO ABOUT THIS ISSUE AND WHY HASN'T GMC BEEN FORCED TO RECALL THESE VEHICLES.
Power train, Feb 26, 2020
HAVE HAD THIS INTO THE DEALER AT THE FIRST OIL CHANGE AND COMPLAINED ABOUT TRANSMISSION SHIFTING ISSUES AND IT BEING UNSAFE TO DRIVE. COMPLAINTS ARE: HARD SHIFT, IT CLUNKS BOTH UPSHIFTING AND DOWNSHIFTING. GOING AROUND CORNERS FROM A STOP THE TRUCK WILL EITHER FALL ON ITS FACE OR JERKS YOU VIOLENTLY FORWARD. IN STOP OR GO TRAFFIC IT IS UNSAFE AND HAPPENS VERY FREQUENTLY- IT RANDOMLY ACCELERATES (JUMPS) QUICKLY ON ITS OWN WITH SLIGHT PEDAL PRESSURE TO THE POINT WHERE YOU CONSTANTLY HAVE TO BE AWARE AND HAVE YOUR FOOT NEAR THE BRAKE OR YOU CAUSE AN ACCIDENT BY REAR ENDING THE CAR IN FRONT, ITS AS IF THE TRANSMISSION ELECTRONICS GET CONFUSED ON HOW TO ACT. FEEL SHUDDERING FROM TRUCK'S MOTOR WHERE COLUMN SHIFT LEVER WOULD SHUDDER VIOLENTLY WHERE I WAS AFRAID IT WOULD VIBRATE OUT OF POSITION. ROUGH IDLE IS INCONSISTENT AT LOWER SPEED WHERE YOU SEE TACH GOING UP AND DOWN. STARTING COLD YOU GIVE IT AN EASY PEDAL TO MOVE AND WOULDN'T GO. TRANS DOESN'T KICK IN UNTIL YOU PRESS HARDER AND SOMETIMES WILL LUNGE. HAVE TAKEN INTO THE VARIOUS DEALERS 5-6 TIMES, VALVE BODY CHANGE, ENGINE MOTOR MOUNTS CHANGE AND DEALERS CAN FIND NO FIX. GM POWERTRAIN WAS EVEN INVOLVED WITH NO HELP. COMPLAINED TO THE GMC HOTLINE AND THEY SAID NEED 12,000 MILES ON TRUCK BEFORE THE TRUCK KNOWS HOW TO DRIVE BECAUSE OF THE 'SMART' TRANSMISSION WHERE IT LEARNS YOU'RE DRIVING HABITS. COMPLAINED THERE ARE 2 OF US THAT DRIVE IT HOW CAN IT LEARN EACH INDIVIDUALS DRIVING WHEN IT DOESN'T REALLY KNOW WHO IS DRIVING. THEY FINALLY SAID THERE IS NOTHING THAT CAN BE DONE FOR IT, THAT IS THE WAY IT IS. THIS ALL HAPPENS SPORADICALLY IN BOTH CITY LOW SPEED DRIVING AND HIGHWAY DRIVING, TURNING, BACKING UP OR GOING FORWARD FROM PARKING. BECAUSE OF THESE ISSUES, DIDN'T REALLY DRIVE THE TRUCK MUCH BECAUSE OF THE PROBLEMS.
Power train, Feb 4, 2020
VEHICLE SHIFTS VERY HARD IN AND OUT OF 1ST AND 2ND GEAR. WHEN STARTING TO GO AT LOW SPEEDS THE VEHICLE ALMOST STOPS WHEN SHIFTING AND THEN JERKS WHEN IT SHIFTS. SAME OCCURS WHEN SLOWING TO A STOP. VEHICLE WAS TAKEN TO THE DEALER AND THE POWER TRAIN WAS REPROGRAMMED. THE ISSUE WAS A LITTLE BETTER FOR A WHILE. A FEW WEEKS LATER THE SAME ISSUE APPEARED AGAIN. VEHICLE WAS TAKEN BACK TO THE DEALER IN JANUARY 2020 AND THERE IS NOW A CHECK ENGINE CODE. DEALER PLANS TO CHANGE 2 HARNESSES AND CHANGE THE FLUID. UNFORTUNATELY THE PARTS ARE ON BACK ORDER WHICH KIND OF TELLS A STORY.
Power train, Jan 30, 2020
TL* THE CONTACT OWNS A 2017 GMC SIERRA. THE CONTACT STATED THAT WHILE DRIVING AT 70 MPH THEIR WAS SUDDEN LOSS OF MOTIVE POWER AND THE GEARS DISENGAGED. THE CONTACT STATED THE CHECK ENGINE WARNING LIGHT ILLUMINATED. THE CONTACT PULLED THE VEHICLE TO THE SIDE OF THE ROAD AND RESTARTED VEHICLE AND THE CHECK ENGINE WARNING LIGHT DISAPPEARED. THE VEHICLE WAS TOWED TO (DUBLIN CHEVROLET GMC BUICK, 2042 VETERANS BLVD, DUBLIN, GA 31021 (478-246-4916) WHERE IT WAS DIAGNOSED THAT THE TRANSMISSION SHOWED EVIDENCE OF LARGE AMOUNTS OF METAL SHAVINGS FROM THE TORQUE CONVERTER. THE OIL PAN ALSO SHOWED EVIDENCE BURNT METAL. THE VEHICLE WAS NOT REPAIRED. THE MANUFACTURER WAS NOTIFIED OF THE FAILURE AND A CASE WAS OPENED. THE FAILURE MILEAGE WAS 61,719.
Power train, Dec 30, 2019
WHILE OPERATING VEHICLE ON HIGHWAY, I EXPERIENCE A SHAKE/SHUDDER WHEN AT SPEEDS OF 50 MPH AND HIGHER. VEHICLE WAS TAKEN TO DEALER STATED THAT THE TORQUE CONVERTER DID SHUDDER. DEALER CHANGED TRANSMISSION FLUID AND I WAS ADVISED TO DRIVE FOR 200 MILES TO SEE IF PROBLEM WAS CORRECTED. SHUDDER STILL REMAINS AND NOW THE VIBRATION IS CONSTANT AT 70 MPH. I CALLED DEALER AGAIN WHO SAID THAT IT WAS PROBABLY A TIRE BALANCE ISSUE. I ARGUED WITH THEM AND STATED I HAD NO SUCH ISSUE BEFORE FIRST BRINGING VEHICLE IN. DEALER IS SETTING UP APPOINTMENT FOR ME TO TAKE IN AGAIN. VIBRATIONS HAVE LITERALLY CAUSED MY 6 YR OLD DAUGHTER TO VOMIT ON 3 DIFFERENT OCCASIONS WHEN IN THE VEHICLE. SHE HAS ONLY BEEN IN VEHICLE 5 OR 6 TIMES. VEHICLE FEELS UNSAFE AT HIGHWAY SPEEDS. I HAVE READ MANY FORUMS ONLINE STATING THIS ISSUE IS ON MANY VEHICLES GM HAS MADE. I AM CURIOUS AS TO WHEN GM WILL BE MANDATED TO TAKE CORRECTIVE ACTION OR BUY THE VEHICLES BACK FROM THE OWNERS.
Power train, Dec 30, 2019
THERE IS A SHUTTERING IN THE TRANSMISSION AS THE VEHICLE ATTEMPTS TO CLIMB SLIGHT/STEEP GRADES AT SLOW TO MEDIUM SPEEDS. AROUND 1500 RPM THE VIBRATION IS SENT THROUGHOUT THE WHOLE VEHICLE. HAVING TO INCREASE ACCELERATION TO ALLOW THE TRUCK TO SHIFT PROPERLY TO OVERCOME THE LACK OF POWER HAS CREATED A DANGEROUS SITUATION WHILE NAVIGATING UP SNOWY/ICE HILLS. THE VEHICLE ALSO PERFORMS A LURCHING OR SUDDEN SPEEDING UP WHEN DOWNSHIFTING WHEN SLOWING TO COME TO A STOP. DEPENDING ON ROAD CONDITIONS THIS CREATES A DANGEROUS SITUATION WHEN APPROACHING ICY/SLIPPERY INTERSECTIONS.
Power train, Dec 4, 2019
VEHICLE IS SHUDDERING AND SHACKING AT SPEEDS ANY WHERE FROM 35 TO 55 MPH. I TOOK IT TO THE DEALERSHIP AND WAS TOLD IT'S A KNOWN TORQUE CONVERTER ISSUE.
Power train, Vehicle speed control, Nov 15, 2019
TL* THE CONTACT OWNS A 2017 GMC SIERRA 1500. ON SEVERAL OCCASIONS, THE ACCELERATOR PEDAL WAS DEPRESSED; HOWEVER, THE VEHICLE FAILED TO RESPOND. ON ONE OCCASION, THE GEAR SHIFT LEVER WAS PLACED IN REVERSE AND THE ACCELERATOR PEDAL WAS DEPRESSED; HOWEVER, THE RPMS REVVED WITHOUT THE VEHICLE RESPONDING. THE VEHICLE WAS TAKEN TO GREG LAIR BUICK GMC (16200 CANYON DR, CANYON, TX 79015, (806) 553-5706) ON TWO SEPARATE OCCASIONS; HOWEVER, THE TRANSMISSION TECHNICIAN WAS NOT AVAILABLE TO DIAGNOSE THE VEHICLE. THE VEHICLE WAS NOT REPAIRED. THE MANUFACTURER WAS NOT NOTIFIED OF THE FAILURE. THE APPROXIMATE FAILURE MILEAGE WAS 33,042.
Power train, Nov 6, 2019
THE 8 SPEED TRANSMISSION SHIFTS HARD GOING FROM 1ST TO 2ND. IT CANT DECIDE WHAT GEAR IT WANTS AT SPEEDS AROUND 40MPH. IT HAS REVVED UP AND THEN SLAMMED INTO GEAR GOING INTO GARAGE AND HAS EVEN DONE IT GOING INTO A PARKING SPOT. THANK GOD NO ONE WAS IN FRONT OF ME! THE TRUCK HAS DONE THIS SINCE NEW. DEALER HAS REPROGRAMMED THE SOFTWARE PER GM, CHANGED THE TRANSMISSION FLUID TO NO AVAIL. DEALER HAS BEEN GREAT IN TRYING TO FIND AND REPAIR ISSUE BUT ALL THEY TELL ME IS GM IS AWARE OF ISSUE BUT DOES NOT KNOW WHAT TO DO. THE ONLY THING THEY ARE ALLOWED IS TO REPROGRAM THE SOFTWARE AND SEND IT HOME. THE DEALER HAS EVEN TOLD ME THEY HAVE SEVERAL CUSTOMERS WITH THIS ISSUE IN ONLY THE 8 SPEED TRANSMISSION. I KNOW HOW TO FIX IT, REPLACE THE TRANSMISSIONS WITH THE NEW 10 SPEED. GM HAS EVEN SAID THAT IS WHY THEY CAME OUR WITH IT BECAUSE THE 8 SPEED HAS ISSUES. I KNOW GM WILL SAY IT IS NOT A SAFETY ISSUE BUT IF A VEHICLE JUMPS INTO GEAR AND HITS A PEDESTRIAN, WHO WILL BE TO BLAME! MY TRUCK HAS 46,000 MILES AND IT HAS DONE THIS SINCE IT WAS NEW.
Power train, Nov 1, 2019
TL* THE CONTACT OWNS A 2017 GMC SIERRA 1500. WHILE DRIVING AT LOW SPEEDS, THE VEHICLE VIOLENTLY DOWNSHIFTED FROM FIRST INTO SECOND GEAR. THERE WERE NO WARNING INDICATORS ILLUMINATED. THE VEHICLE WAS TAKEN FOUR TIMES TO DEMAROIS BUICK GMC MERCEDES-BENZ (3115 W BROADWAY ST, MISSOULA, MT 59808, (406) 721-4000) WHERE IT WAS DIAGNOSED THAT THE TRANSMISSION NEEDED TO BE REPROGRAMMED. THE VEHICLE WAS REPAIRED, BUT THE FAILURE RECURRED. THE MANUFACTURER WAS CONTACTED AND PROVIDED CASE NUMBER: 9-526--2561452. THE FAILURE MILEAGE WAS 20,000.
Power train, Oct 28, 2019
MY 2017 GMC SIERRA SHUTTERS AND JERKS WHEN GOING INTO AND OUT OF 1ST GEAR AND GOING AROUND CORNERS WHEN IT CHANGES GEARS. ESPECIALLY WHEN COLD. DOES NOT HAPPEN ALL THE TIME. AT TIMES IT HAS JERKED INTO AN INTERSECTIONAND WAS SCRY. MY WIFE WILL NOT DRIVE THIS VEHICLE. HAVE HAD IT LOOKED AT NUMEROUS TIMES AND THEY HAVE CHANGED THE FLUID. THEY TELL ME I HAVE A QUIRKY TRANS OR IT IS INHERENT TO THIS TRANSMISSION. IT IS EXTREMELY FRUSTRATING AND SCARY AT TIMES. I DON'T KNOW WHAT TO DO TO GET GM TO FIX IT. THIS HAS BEEN GOING ON SINCE I PURCHASED THE TRUCK ON 10/31/2017.
Suspension, Power train, Other or unspecified, Oct 5, 2019
THE VEHICLE EXHIBITS VIBRATIONS THAT CAN BE RATHER EXTREME AT TIMES. IT SEEMS TO BE MOST NOTICEABLE IN THE 70-75 MPH RANGE BUT CAN SOMETIMES BE FELT AT OTHER SPEEDS. IT FEELS LIKE THE VIBRATION ORIGINATES FROM THE REAR OF THE VEHICLE. TWO DEALERSHIPS HAVE REPLACED MULTIPLE PARTS AND HAVE PERFORMED NUMEROUS ALIGNMENTS AND ROAD FORCE BALANCES BUT CAN NOT IDENTIFY/REMEDY THE PROBLEM. THERE ARE THOUSANDS OF COMPLAINTS ON MULTIPLE ONLINE FORUMS OF THIS SAME ISSUE FOR 2014-2015 GM 1500 SERIES PICKUP TRUCK. SO FAR THERE HAS BEEN NO FIX FOR THEM EITHER. GM TREATS IT AS AN ANNOYANCE IN THE COMFORT OF THE RIDE, HOWEVER IF THEY CAN NOT IDENTIFY THE ISSUE HOW DO THEY KNOW IT IS NOT A SAFETY RISK.
Power train, Oct 4, 2019
WE WERE DRIVING UP A SLIGHT INCLINE IN A PARKING GARAGE WHEN THE ENGINE STARTED SPUTTERING AND SHUT OFF. AFTER SEVERAL ATTEMPTS IT STARTED AND WE WERE ABLE TO MAKE IT TO A PARKING SPACE WITH THE ENGINE STILL SPUTTERING. I RECEIVED A NOTIFICATION FROM THE TRUCK, DECREASED ENGINE POWER. THE NEXT DAY I BROUGHT IT TO BE CHECKED BY THE LOCAL GMC DEALER. THEIR DIAGNOSIS IS VAPOR LOCK WHEN THE FUEL PUMP GETS NEAR OR OVER 100 DEGREE. ITS MY OPINION THAT GMC PLACED A FAULTY PART WHEN MANUFACTURING THE VEHICLE. I WOULD LIKE THIS TO BE CONSIDERED FOR RECALL.
Power train, Visibility/wiper, Oct 3, 2019
MY WINDSHIELD WIPER FLUID ONLY SPRAYS OUT 30% OF THE TIME. USUALLY IN THE MORNING THEN ANY OTHER TIME OF THE DAY IT WILL NOT SPRAY OUT. THEY REPLACED THE PUMP AND THAT DID NOT FIX IT AND THEY WON'T DO ANYTHING ELSE AND NOW IT IS OUT OF WARRANTY. WHEN RUNNING LOWER RPMS DRIVING THE TRUCK IT BEGINS TO FEEL LIKE ITS SHAKING FORWARD AND BACKWARDS, LIKE A SHUDDERING FEELING. I HAVE READ ABOUT OTHER PEOPLE HAVING THIS PROBLEM AND IT DESCRIBES MINE PERFECTLY. I HAVE THE 8SPEED

TL* THE CONTACT OWNS A 2017 GMC SIERRA 1500. WHILE THE VEHICLE WAS IDLING AT A TRAFFIC LIGHT, IT BEGAN TO RATTLE. THERE WERE NO WARNING INDICATORS ILLUMINATED. THE VEHICLE WAS TAKEN TO FRESNO BUICK GMC (LOCATED AT 5515 N BLACKSTONE AVE, FRESNO, CA 93710, (559) 742-4113) WHERE AN UNKNOWN DIAGNOSIS AND REPAIR WERE PERFORMED; HOWEVER, THE FAILURE CONTINUED. THE MANUFACTURER WAS NOT NOTIFIED. THE FAILURE MILEAGE WAS 24,000.
Power train, Sep 11, 2019
SINCE DECEMBER OF 2017 THE TRANSMISSION, WHEN COLD, AT APPROX. 25 MPH AND AT 40-44 MPH WHEN NEUTRAL THROTTLE IS APPLIED, BANGS BETWEEN GEARS FORCING THE OPERATOR TO EITHER ACCELERATE OR DECELERATE SO THE CONDITION WILL CEASE. IF THERE IS NO CHANGE BY THE OPERATOR, IT FEELS AS IF THE TRANSMISSION WILL BREAK THE U-JOINTS IN THE DRIVELINE OR BLOWOUT THE REAR-END GEARS. I HAVE MADE NUMEROUS ATTEMPTS WITH GMC TO REMEDY THE ISSUE TO NO AVAIL. THE VEHICLE HAS BEEN IN THE DEALERSHIP IN EXCESS OF 40 DAYS FOR THE SAME PROBLEM WITH NO RESOLUTION
Power train, Vehicle speed control, Jul 12, 2019
THE TRUCK LURCHES FORWARD AS IF THE ACCELERATOR IS BEING DEPRESSED WHILE COMING TO A STOP OBVIOUSLY WHILE DEPRESSING THE BRAKE. THIS CAUSES DANGEROUS SITUATIONS EVERY DAY IN TRAFFIC. I HAVE NOT FOUND ANY SOLUTIONS TO THE PROBLEM ONLINE. REPROGRAMMING COMPUTER AND REPLACING OTHER SPEED CONTROL MODULES HAS NOT SOLVE THE PROBLEM FOR OTHER DRIVERS.
Power train, Jul 9, 2019
8 SPEED TRANSMISSION IS DANGEROUS. UNDER LIGHT THROTTLE, THE VEHICLE WILL MAKE A LOUD POPPING NOISE AND LURCH FORWRWARD. LIKE STOPPING AT A STOP LIGHT, DRIVING THROUGH A DRIVE-THRU. MY TRUCK WILL SHAKE VIOLENTLLY.. DEALER SAYS ITS THE TRANSMISSION. WHEN I TRY TO ENTER MY GARAGE THE TRUCK WILL SORT OF JUMP FORWARD. DELEAR SAYS ITS TORQUE CONVERTER SUTTER. TRANSMISSION HAS BEEN WORKED ON 3 TIME. IT SEEMS TO GET WORSE. DELEARS SAYS THE 8 SPEED TRANSMISSION HAS MANY ISSUES BUT GM DOES NOT HAVE A FIX. THESE 8 SPEED TRANSMISSIONS WILL END UP KILLING FOLK.. THIS STUFF HAPPENS ON A DAILY BASIS

MY TRUCK SHIFTS VERY HARD BETWEEN GEARS, ESPECIALLY 1ST TO 2ND. FEELS LIKE GETTING REAR ENDED SOMETIMES. IT ALSO HESITATES DAILY WHEN BACKING OUT OF MY DRIVEWAY AND PUTTING IT FROM REVERSE TO DRIVE. YOU DON'T KNOW WHEN IT WILL ACTUALLY ENGAGE MAKING IT DANGEROUS WHEN PULLING OUT INTO THE STREET. ITS DEFINITELY AN ISSUE WITH THE TRANSMISSION BUT NO FIXES OFFERED FROM DEALER YET.
