POWER TRAIN
AFTER COMING TO A COMPLETE STOP AT TRAFFIC STOP LIGHT TRUCK'S TRANSMISSION MADE A LOUD "CLUNK" SOUND. WHEN ATTEMPTING TO ACCELERATE ON THE GREEN LIGHT TRUCK, INITIALLY WOULD NOT MOVE THEN IT LERCHED FORWARD BUT WOULD NOT SHIFT OUT OF FIRST GEAR. PULLED OFF MAIN ROAD AND INTO A PARKING LOT WHERE I SHIFTED TRUCK INTO PARK AND TURNED OFF THE ENGINE. AFTER WAITING A COUPLE OF MINUTES I RESTARTED THE TRUCK, SHIFTED INTO DRIVE AND PULLED BACK ONTO THE STREET, BUT THE TRUCK STILL WOULD NOT SHIFT OUT OF FIRST GEAR.

ENGINE, FORWARD COLLISION AVOIDANCE: ADAPTIVE CRUISE CONTROL, BACK OVER PREVENTION: WARNINGS
ON OR ABOUT 10-14-2020 I HAD GOT A CALL FROM MY NIECE THAT SHE WAS AT A PARKING LOT AND THE TRUCK DIDN'T WANT TO RUN THE SAME. SHE WAS PASSING A INTERSECTION WHEN SHE HEARD A VERY LOUD POP NOISE AND A VERY SCARY NOISE COMING FROM THE ENGINE. THE NOISE DID SHACK HER SOME BUT WHEN SHE NOTICES THE TRUCK HAD LOST ITS POWER SHE WAS MORE SCARE THAT SHE WAS GOING TO GET HIT BY A OTHER CAR CAME OUT TO BE THE LIFTERS AND CAMSHAFT . WHERE THEY BEEN HAVING CLASS ACTSIONS LAW SUITS WITH GM MOTORS FOR THE SAME PROBLEM WITH OTHER GMC YEAR FROM 2009-2015 5.3 VORTEX ENGINS AND GMC KNEW ABOUT IT BEFORE THE SOLD THE VERY FIRST TRUCK ITS A $10,000.00 DALLORS REPAIR AND WITH THE BANK FINANCE I WILL BE PAYING MORE THEN 25,000.00 AFTER COST AND THIS TRUCK BLUE BOOK ITS AT 15,000.00 LAST TIME I CHECK IT SO ITS NOT WORTH PUTTING SO MUCH MORE MONEY FOR THAT YEAR OF TRUCK. I HAD TRYED TO WORK THINGS OUT WITH THE DEALERSHIP AS WELL WITH GM MOTORS AND HAD NO LUCK OR EVEN A CALL BACK FROM BOTH SIDES. I ASK THAT IF YOU CAN INVESTIGATE THIS MATTER SOME MORE I WILL GLADLY APPRECIATE IT. THANK YOU FOR YOUR TIME.

2019 GMC SIERRA WITH 56K MILES WHEN ACCELERATING TRANSMISSION SEEMS TO GET STUCK IN FIRST GEAR MAKES IDOL SOUNDS RPMS JUMP UP THEN HARD SHIFT INTO SECOND, MAKES THE TRUCK JERK WHEN IT HAPPENS, SINCE THE ISSUE STARTED IT HAPPENS EVERY TIME I DRIVE IT. I TOOK IT TO LOCAL GMC DEALERSHIP ON 2/9/21 MANAGER SAID 'YES IT'S A KNOWN ISSUE WITH GMC & THAT YEAR MODEL TRUCKS' 2 DAYS LATER CALLED TO SEE STATUS OF TRUCK MANGER SAID HIS TRANSMISSION GUY FOUND THE ISSUE AND FIXED IT SAID COMPUTER AND TRANSMISSION NOT TALKING TO EACH OTHER DID A 'TRANSMISSION RELEARN' WAS COVERED UNDER POWER TRAIN WARRANTY. I HAD THE TRUCK BACK LESS THAN 24 HOURS AND NOW BACK TO HAVING THE SAME ISSUES AGAIN! CLEARLY IT'S NOT FIXED AND CONCERNING THIS IS GOING TO BE A SAFETY ISSUE WHILE DRIVING! GMC 'KNOWN' ISSUE THEN ISSUE A RECALL AND FIX IT RIGHT THE FIRST TIME!

ENGINE, POWER TRAIN
VIOLENT AND ERRATIC SHIFTING DURING ACCELERATION AND DECELERATION... A SIMULTANEOUS POP AND JERK HAPPENS... ALSO WHEN ACCELERATING AND HITTING PASSING GEAR THE TRUCK SEEMS TO STALL OUT AND THEN QUICKLY ENGAGES TO APPLY MORE POWER THAN EXPECTED... THIS CAN BE DANGEROUS FOR A DRIVER ATTEMPTING TO MERGE ONTO HIGHWAYS/HIGHWAYS! THE JERKING OCCURS ON A REGULAR BASIS AND AT VARIOUS SPEEDS ON VARIOUS HIGHWAYS...

FUEL/PROPULSION SYSTEM
2015 GMC SIERRA 2500 DURAMAX DRIVING EAST WITH THE FLOW OF TRAFFIC ON 80 REACHING THE SUMMIT TOWARDS TAHOE. WE SUDDENLY EXPERIENCE AT "CHANGE FUEL FILTER" WARNING WHICH ONLY LASTED APPROXIMATELY 20 SECONDS BEFORE THE MESSAGE THEN READ "DERATING". UPON THIS SECOND NOTIFICATION WE IMMEDIATELY LOST POWER TO THE ENGINE WHICH RESULTED IN REDUCED BRAKING CAPABILITY AND STEERING AT LITERALLY THE TOP OF THE MOUNTAIN. WE WERE TRAVELING IN SNOWY CONDITIONS WITH MANY SEMI TRUCKS AROUND US. WE TRIED TO SAFELY DRIFT TO THE SHOULDER TO THE SAFEST POSSIBLE PLACE. THE SUDDEN LACK OF POWER LEFT MY FAMILY, INCLUDING 3 CHILDREN, IN A VERY DANGEROUS POSITION. WE ENDED UP BEING STRANDED WITH TOW TRUCKS BEING VERY SCARCE AND CHALLENGING TO FIND. THE NEAREST RENTAL CAR TOOK 2 HOURS TO GET TO, AND WE HAD TO SHUFFLE KIDS ALL OVER. ONE CHILD WAS CRYING AND SCARED TO DEATH AT ALL THE CARS ZOOMING BY AND OUR INABILITY TO MOVE. IT APPEARS THAT THE CP4 FUEL PUMP MAY HAVE FAILED LEAVING US ALMOST INSTANTANEOUSLY IN AN UNSAFE SITUATION.

STRUCTURE:BODY
THE DRIVER'S SIDE DOOR HANDLE DOESN'T WORK. I BELIEVE THIS WAS A 'RECALL' BUT I COULDN'T GET THE DEALERSHIP TO FIX IT. REAL FUN HAVING TO ROLL DOWN THE WINDOW JUST TO OPEN THE DOOR FROM INSIDE, ESPECIALLY WHEN THE DOOR'S WINDOW IS FROZEN. OBVIOUSLY THE VEHICLE IS IN A PARKED POSTION. THE TRUCK ONLY HAD 149,000 WHEN THE HANDLE STOPPED WORKING.

CONTACTED GM CORPORATE, THEY TOLD ME THEY CAN'T HELP ME AND TO CALL THE LOCAL DEALER TO SCHEDULE GETTING THE SERVICE TO GET DONE. LOCAL DEALER DOES NOT HAVE ANY INFORMATION, IS NOT ABLE TO GET PARTS, AND IS NOT WILLING TO DO SERVICE AS IT WILL NOT BE COVERED UNDER WARRANTY AS ITS NOT IN GM'S SYSTEM. GM IS CONTINUING TO STALL AND THIS HAS BEEN A FOUR YEAR ORDEAL. LOCAL DEALER HAS NO TIMEFRAME OF WHEN THE SYSTEM WILL BE UPDATED SO THEY CAN BEGIN THE WORK, THEY HAVE NO CLUE WHEN THEY WILL BE ABLE TO GET PARTS OR IF THEY WILL EVEN BE ABLE TO GET PARTS.

UNKNOWN OR OTHER
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

REAR WINDOW DEFROSTER STARTED SMOKING AND CREATED A BURNING PLASTIC SMELL. AFTER TURNING OFF THE REAR DEFROSTER THE REAR WINDOW EXPLODED/SHATTERED IN PLACE. I SEE THERE IS A RECALL IN CANADA, BUT NOT HERE. THIS IS HAPPENING HERE AND I HAVE READ OF MANY OTHERS WITH SAME ISSUE. FIRE AND BROKEN GLASS IS NOT SAFE AND SHOULD BE ADDRESSED

IT HAS A PROBLEM WITH CYCLING OF THE THERMOSTAT THAT CAUSES STRESS FRACTURES ON THE RADIATOR LEADING TO COOLANT LEAKS. ATTACHED ARE GM BULLETINS ON THE 2014 AND 2015 MODELS. AS ONE CAN SEE THEY HAVE PROVIDED SPECIAL COVERAGE. MY RADIATOR IS LEAKING JUST LIKE THE SERVICE BULLETIN SAYS. THIS NEEDS TO BE RECALL.

STEERING
I HAVE 48,000 MILES ON MY TRUCK , 2019 MODEL. I JUST EXPERIENCE MY STEERING WHEEL TO GET STIFF WITHOUT THE POSSIBILITY TO MANEUVER IT WHEN IT WAS STATIONARY. MY DASH BRINGS A TWO MESSAGES, " SERVICE ESC," " SERVICE POWER STEERING." I WENT TO THE DEALERSHIP TO CHECK IF THERE HAS BEEN ANY RECALLS AND THE ANSWER THE WAS NEGATIVE. I DID MY RESEARCH AND ON PREVIOUS MODELS THERE HAS BEEN EXISTING RECALLS ON THIS ELECTRICAL ENGINEERING ISSUE. " 2018 GMC SIERRA MODELS AND BELOW ," I SINCERELY FEEL THIS SHOULD BE FILE AS SAFETY COMPLAINT. THE VEHICLE IS TO NEW HAVE THIS SORT OF ISSUE. IT'S NOT A MECHANICAL FAILURE BUT A ELECTRICAL ENGINEERING PROBLEM. *TR
