2019 GMC SIERRA 1500 Complaints

STARTED WITH IGNITION BUTTON PUT IN REVERSE BACKED UP WENT TO STOP AND REALISED BRAKES ARE NOT WORKING AS USUAL HAD TO STAND ON PEDAL TO STOP. CHECKED MIRRORS TO MAKE SURE I DIDN'T HIT ANYTHING I DIDN'T .THOUGHT MAYBE I HIT SIDE OF BRAKE PEDAL SO I APPLIED THE BRAKE AGAIN AND FIGURED I LOST BRAKE BOOST. I CHECKED FOR WARNING LIGHTS THERE WERE NONE .BRAKES DID NOT WORK PROPERLY UNTIL I RESTARTED TRUCK .THEN I FELT THE PEDAL REACTED PROPERLY . CALLED DEALER THEY DID A RECALL BUT RECALL DIDN'T SPECIFICALLY MATCH MY BRAKE LOSS. I CAN ONLY HOPE IT'S FIXED

MY PICKUP STARTED, I PULLED OUT ON ROAD AND SPED UP TO 35 MPH, WHEN I STEPPED ON BRAKES TO SLOW DOWN THEY WERE UNRESPONSIVE, SO I BEGAN PUMPING. THEY FELT VERY HARD TO PUMP AND WERE NOT SLOWING THE TRUCK DOWN. LIGHTS CAME ON SAYING SERVICE BRAKES ETC. AS I COASTED TO TRY TO SLOW DOWN OFF SIDE OF ROAD. I HAD TO KEEP PUMPING THE BRAKES DOWN TO FLOORBOARD AND I?M NOT SURE THEY WERE EVEN WORKING. I LOST POWER STEERING AND WAS ALMOST INVOLVED IN A SERIOUS REAR-END COLLISION. 4 MESSAGES APPEARED ON DIGITAL DASH WHILE DRIVING. SERVICE ESC, BRAKE SYSTEM FAILURE 62 MPH TOP SPEED, SERVICE TRAILER BRAKE SYSTEM, STEERING ASSIST REDUCED. I HAD TO PRESS BRAKE PEDAL TO THE FLOOR WITH EXTREMELY EXCESSIVE FORCE TO GET TRUCK TO STOP. THIS FAILURE COULD HAVE EASILY RESULTED IN VEHICLE ACCIDENT, OR EVEN A FATALITY ACCIDENT. I DOUBT I WILL EVER CARRY MY FAMILY IN THE TRUCK AGAIN DUE TO THIS AND I CERTAINLY WILL NOT ALLOW MY CHILDREN TO DRIVE THE TRUCK. THIS IS THE 5TH TIME THIS HAS HAPPENED TO MY TRUCK.

I HAVE HAD THE 2019 SIERRA 1500 AT4 WITH 6.2 LITER ENGINE IN THE SHOP (8) TIMES SINCE PURCHASING IT IN LATE AUG 2019 FOR MULTIPLE ISSUES, INCLUDING THE ISSUES RELATING TO THE BRAKE SOFTWARE RECALL. THIS RESULTED IN ME ROLLING THROUGH A STOP SIGN WITHOUT ANY BRAKES. LUCKILY THERE WAS NO ONCOMING TRAFFIC. AS AN ENGINEER, I HAVE NO CONFIDENCE THAT THE ISSUE HAS BEEN FIXED LONG TERM BY GM. MY FAMILY WILL NO LONGER RIDE IN THE TRUCK WITH ME. AS A RESULT, I HAVE RETAINED AN ATTORNEY FOR THE PURPOSE OF FILING SUIT AGAINST GM FOR SELLING ME AN UNSAFE LEMON. EVEN FURTHER CONCERNING IS THE FACT THAT ON (2) OCCASIONS THE PARKING BRAKE HAS ENGAGED WHILE DRIVING DOWN THE HIGHWAY AT 55 MPH. ONE TIME WHILE IN 4WD IN SNOW, AND THE OTHER TIME WHILE IN 2WD ON DRY PAVEMENT. THE FIRST TIME THERE WAS A DIAGNOSTIC CODE ASSOCIATED WITH THE PARKING BRAKE ENGAGING RANDOMLY. THE SECOND TIME, THERE WAS NO DIAGNOSTIC CODE PRESENT. THE FIRST ISSUE WITH BRAKING BEGAN 11/14/2019, AND THE MOST RECENT ISSUE OCCURRED ON 2/2/2020 EVEN AFTER ALL RECALL "FIXES" HAVE BEEN APPLIED. *JS

I WAS DRIVING TO WORK IN SNOWY CONDITIONS AND ON A VERY SLIGHT BEND ON A FLAT PUBLIC HIGHWAY MY TRUCK STARTING SLIDING AND AS I TURNED THE WHEEL AND APPLIED THE BRAKES THE USUAL ACTION OF ANTILOCK BRAKES DID NOT WORK AS INTENDED ALLOWING ME TO STEER CLEAR OF THE OBSTACLE CAUSING ME TO WRECK.2018 GMC SIERRA 1500

ON TWO OCCASIONS THE VEHICLE LOST THE POWER BRAKES FUNCTION. NUMEROUS DASH ALERTS STATING INCLUDING "SERVICE ESC" "BRAKE SYSTEM FAILURE 62MPH TOP SPEED" "SERVICE TRAILER BRAKE SYSTEM" "STEERING ASSIST IS REDUCED DRIVE WITH CARE" ALONG WITH A CHECK ENGINE LIGHT. THE BRAKES PEDAL HAD TO BE PUSHED TO THE FLOOR TO SLOWLY COME TO A STOP. BOTH TIMES WERE IN A PARKING LOT. ONE OF WHICH TIMES I WAS MOVING. DEC 26TH AND AGAIN ON JAN 16TH 2019. THE VEHICLE WAS TOWED TO THE DEALERSHIP ON BOTH INCIDENTS.

4 MESSAGES APPEARED ON DIGITAL DASH WHILE DRIVING. SERVICE ESC, BRAKE SYSTEM FAILURE 62 MPH TOP SPEED, SERVICE TRAILER BRAKE SYSTEM, STEERING ASSIST REDUCED. I HAD TO PRESS BRAKE PEDAL TO THE FLOOR WITH EXTREMELY EXCESSIVE FORCE TO GET TRUCK TO STOP. NOTE THAT NONE OF THE 4 MESSAGES STATE THE VEHICLE WILL BE EXTREMELY DIFFICULT TO STOP OR SHOULDN'T BE DRIVEN, BUT RATHER THE VEHICLE WOULDN'T EXCEED 62 MPH. IT SHOULD HAVE REDUCED THE SPEED TO MUCH LESS, MAYBE 10 TO 15 MPH. THIS FAILURE COULD HAVE EASILY RESULTED IN VEHICLE ACCIDENT, OR EVEN A FATALITY ACCIDENT. I DOUBT I WILL EVER CARRY MY FAMILY IN THE TRUCK AGAIN DUE TO THIS AND I CERTAINLY WILL NOT ALLOW MY CHILDREN TO DRIVE THE TRUCK.

MY PICKUP STARTED, I PULLED OUT ON ROAD AND SPED UP TO 35 MPH, WHEN I STEPPED ON BRAKES TO SLOW DOWN THEY WERE UNRESPONSIVE, SO I BEGAN PUMPING. THEY FELT VERY HARD TO PUMP AND WERE NOT SLOWING THE TRUCK DOWN. LIGHTS CAME ON SAYING SERVICE BRAKES ETC. AS I COASTED TO TRY TO SLOW DOWN OFF SIDE OF ROAD. I HAD TO KEEP PUMPING THE BRAKES DOWN TO FLOORBOARD AND I'M NOT SURE THEY WERE EVEN WORKING AS I COASTED SAFELY OFF SIDE OF ROAD TO A STOP, I TURNED ENGINE OFF IMMEDIATELY CALLING MY DEALERSHIP SERVICE DEPARTMENT. I WOULDN'T DRIVE IT ANY FURTHER AS I FELT I HAD NO BRAKES WHATSOEVER. DEALERSHIP HAD IT TOWED TO THEIR SHOP. THE NEXT AFTERNOON I SPOKE WITH THEM. THEY STATED IT WAS A KNOWN ISSUE AND THAT A RECALL HAD BEEN ISSUED (SEE RECALL NUMBER BELOW) BUT I NEVER RECEIVED IT. I DID RECEIVE A SEAT BELT RECALL SO I KNOW THEY HAVE MY CORRECT ADDRESS. I WAS TOLD IT WAS SOME PROBLEM WITH A MODULE AND I CAN COME PUCK TRUCK UP. IT WAS SCARY WHEN IT HAPPENED. I PURCHASED THIS PICKUP NEW ON AUGUST 21, 2019. RECALL NUMBER: RECALL-N192268090 (PER DEALERSHIP SERVICE DEPARTMENT)

EVERY SINGLE DAY I BACK OUT OF MY DRIVEWAY AND WHEN I SHIFT INTO DRIVE AND STEP ON THE GAS THE TRUCK MOVES FORWARD SLIGHTLY AND THE RPMS WIND UP BUT THE TRUCK BOGS DOWN LIKE IT'S GOT A FUEL CLOG THEN IT SHIFTS INTO 2ND AT A HIGH RPM AND JERKS FORWARD LIKE SOMEONE POPPED A CLUTCH. THIS IS A MAJOR SAFETY ISSUE BECAUSE ONCE THIS WINTER IT HAPPENED AND THE REAL WHEELS SPUN AND THE BACK END SLID OUT ON THE ICE AND THE NOSE OF MY TRUCK WOUND UP IN THE ONCOMING LANE OF TRAFFIC. DEALER AND GMC SAY THAT A 'HARD SHIFT' IS A KNOWN ISSUE AND THE TRUCK IS 'WORKING AS DESIGNED' AND THERE IS NOTHING THEY WILL DO FURTHER. I HAVE HAD IT IN THE SHOP 3X ALREADY. I HAVE READ FORUMS SPEAKING OF MANY PEOPLE HAVING SIMILAR ISSUE WITH 2019 GMC TRUCKS AND NO FIX FROM GMC. THIS IS NOT NORMAL, SAFE AND I'M SURE NO ENGINEER DESIGNED THIS TRANSMISSION TO WORK THIS WAY.

STARTED TRUCK AND MANY SERVICES LIGHTS CAME ON SERVICE ESC, BRAKES LIGHTS, STEERING LIGHTS ALL WARNINGS. ON STAR CALLED AND SAID I HAD A BRAKE FAILURE. I WAS BACKING OUT OF DRIVEWAY AND COULD HARDLY STOP THE TRUCK AS I WAS APPROACHING THE ROAD

AFTER MY RECALL WAS FIXED MY TRUCK LOCKED INTO 4 WHEEL DRIVE AND I LOST CONTROL OF ALL MY SAFETY FEATURES. MY LIGHTS WOULD NOT WORK. THEY FIXED WHAT THEY SAID WAS A GLITCH IN THE RECALL AND 3 WEEKS LATER MY ENGINE LIGHT CAME ON AGAIN AND MY BRAKE SYSTEM STARTED TO SHOW LIGHTS. THEY RECALIBRATED THE BRAKE SYSTEM RECALL AGAIN.
