SERVICE BRAKES, ELECTRICAL SYSTEM, STEERING
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.

OFTEN TIMES A MESSAGE IS DISPLAYED THAT READS "SERVICE REAR CAMERA". ALSO, WHEN DRIVING THE INFOTAINMENT SYSTEM WILL TURN OFF, REBOOT, OR TURN BLACK INTERMITTENTLY.

SERVICE BRAKES, ENGINE
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

SERVICE BRAKES
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.

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)

SERVICE BRAKES, STEERING
AFTER STARTING MY VEHICLE REMOTELY USING ON-STAR, MY BRAKES STOPPED FUNCTIONING PROPERLY... AFTER REMOTE STARTING THE VEHICLE USING MY ON-STAR APP, WE ENTERED IT, DEPRESSED THE BRAKE AND PRESSED THE START BUTTON. AT THAT TIME I RECEIVED MULTIPLE ERROR MESSAGES, STATING "BRAKE SYSTEM FAILURE, 62 MPH TOP SPEED" "SERVICE ESC" " STEERING ASSIST IS REDUCED DRIVE WITH CARE." I RESTARTED THE VEHICLE A NUMBER OF TIMES AND THE ERROR MESSAGES WENT AWAY. I THEN BEGAN TO DRIVE HOME AND AFTER ABOUT 2 MILES THE ERROR MESSAGES ALL CAME BACK AND MY BRAKES STOPPED FUNCTIONING. I WAS ABLE TO USE THE FULL FORCE OF MY BODY ON THE BRAKES TO GET THE VEHICLE TO COME TO A STOP FROM AROUND 30 MPH IN MY NEIGHBORHOOD. HAD I BEEN ON THE HIGHWAY OR ON THE MAIN STREET I HAD JUST BEEN ON I LIKELY WOULD NOT HAVE BEEN ABLE TO STOP WITHOUT HITTING ANOTHER VEHICLE OR OBJECT.

ELECTRICAL SYSTEM, POWER TRAIN, UNKNOWN OR OTHER
ELECTRIC/ELECTRONIC/COMPUTER ISSUES. MOST ISSUES ARE INTERMITTENT, SOME HAPPEN ALL THE TIME. THE INTERMITTENT ONES SOMETIME HAPPEN IN CLUSTERS (MULTIPLE TIMES A DAY THEN NOT FOR DAYS, WEEKS, MONTHS) A FEW HAVE ONLY HAPPENED ONCE SO FAR. THE FOLLOWING ISSUES HAPPEN ALL THE TIME. DOES NOT COME OUT OF CRUISE CONTROL AUTOMATICALLY DURING COLLISION ALERT. DOES NOT AUTOMATICALLY BRAKE DURING IMMINENT COLLISION WITH AUTO BRAKE FEATURE TURNED ON. SECONDARY BLUETOOTH PHONE DOES OUTGOING CALLS THROUGH TRUCKS INFO SYSTEM. HEADS-UP DISPLAY GIVES DOUBLE TURN DIRECTIONS DURING ROUTE GUIDANCE NAV. BLUETOOTH TEXTING DOES NOT WORK. THE FOLLOWING ISSUES HAPPEN FREQUENTLY. TRANSMISSION BANGS/SHUDDERS PERIODICALLY, ACCELERATING, NOT ACCELERATING, SLOWING DOWN, JUST DRIVING, MOSTLY ON LEVEL GRADE. SOMETIMES STRONG ENOUGH TO FEEL LIKE I WAS REAR ENDED, PASSENGERS HAVE JUMPED MANY RADIO MEDIA ISSUES WITH SOUND AND NAV BOOT UP. DURING PARKING MANEUVER AFTER COMING OUT OF REVERSE AND GOING INTO DRIVE, FORWARD CAMERA WOULD COME ON AND THEN SWITCH TO NAV SCREEN WHEN I TOOK MY FOOT OFF THE BRAKE. TO RESOLVE WOULD GO IN REVERSE THEN BACK TO DRIVE AND THE FRONT CAMERA WOULD STAY ON. AFTER VEHICLE START I GO INTO DRIVE AND FRONT CAMERA COMES ON. SOMETIMES IT DOES NOT IN THE EXACT SIMILAR CIRCUMSTANCES. NO INDICATION FROM FORWARD DETECTION SENSORS. AFTER BACKING OUT OF A PARKING SPOT, GOING INTO DRIVE FORWARD CAMERA COMES ON THEN THE WHOLE SCREEN GOES BRIGHT BLUE, AFTER A FEW SECONDS FORWARD CAMERA COMES BACK ON UNTIL I SPEED UP. OTHER ISSUES NOT SO FREQUENT. HAVE BEEN TO DEALERSHIP OVER 9 TIMES FOR A TOTAL OF 37 DAYS IT WAS IN THE SHOP. GMC CAC USELESS AND DO NOT KNOW THE PRODUCT. DEALERSHIP TECHNICIANS ARE NOT FAMILIAR WITH NEW PRODUCT OR HAVE THE COMPUTER SKILL SET TO FIX.

SERVICE BRAKES, ELECTRONIC STABILITY CONTROL (ESC), STEERING
AFTER USING APP TO START THE VEHICLE, I SAT IN THE DRIVER SEAT DEPRESSED THE BRAKE AND PUSHED THE START BUTTON. IMMEDIATELY A WARNING POPPED UP SAYING ESC NEEDED SERVICE, SERVICE TRAILER BRAKE, SPEED LIMITED TO 62MPH. ADDITIONAL LIGHTS ILLUMINATED INCLUDING BRAKE, TRACTION CONTROL, ABS, AND CEL. SINCE THE DASH INDICATED THAT THE SPEED WAS REDUCED I THOUGHT IT WOULD BE SAFE TO DRIVE, HOWEVER AT THE FIRST TURN I REALIZED MY BRAKES WERE NEARLY GONE AND I WENT THROUGH THE INTERSECTION. THE BRAKES APPEARED TO HAVE LOST THE BOOST AND WERE EXTREMELY HARD TO DEPRESS MAKING IT DIFFICULT TO STOP THE VEHICLE. I LIMPED THE TRUCK HOME AND NOTIFIED THE DEALER. THE NEXT DAY I TRIED STARTING THE TRUCK AND THE BRAKES RETURNED WITH NO DASH MESSAGES ALTHOUGH THE CEL WAS STILL ILLUMINATED. THERE IS A RECALL FOR A SIMILAR ISSUE BUT IT LOOKS LIKE MY VIN IS NOT APART OF IT.

SERVICE BRAKES, STEERING
TL* THE CONTACT OWNS A 2019 GMC SIERRA DENALI. THE CONTACT STATED THAT WHILE DRIVING AT AN UNDISCLOSED SPEED, THE POWER FAILED TO OPERATE AS DESIGNED. THE BRAKE PEDAL WAS DEPRESSED HOWEVER, THE STOPPING DISTANCE WAS EXTENDED. THE VEHICLE WAS TAKEN TO (BALLAS BUICK GMC 5715 CENTRAL AVE, TOLEDO, OH 43615 (419) 464-7699) TO BE DIAGNOSED. THE TECHNICIAN STATED THAT THERE WAS A LOSS OF COMMUNICATION BETWEEN THE VEHICLE COMPUTERS TO THE POWER STEERING MODULE. THE VEHICLE REMAINED IN DEALER CUSTODY FOR SEVERAL WEEKS BUT WAS NOT REPAIRED. THE MANUFACTURER WAS INFORMED OF THE FAILURE. THE FAILURE MILEAGE WAS 4,500.

POWER TRAIN
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.

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.

SERVICE BRAKES, ELECTRONIC STABILITY CONTROL (ESC)
FOUR DAYS AFTER HAVING A RECALL PERFORMED I WAS GETTING AN ERROR FOR MY ECS AND ABS BEING DISABLED. THE TRUCK LOST ALMOST COMPLETE CONTROL OF BRAKING. I TOOK IT BACK TO THE DEALERSHIP TO BE REPROGRAMMED AND THE SAME THING HAPPENED A WEEK LATER. BOTH TIMES THIS HAPPENED WHEN THE TRUCK WAS FIRST STARTED.

UPON STARTING THE VEHICLE AND TAKING OFF AFTER REMOTELY STARTING IT, MULTIPLE WARNINGS POPPED UP ON THE TRUCKS DIC. THEY WERE, SYSTEM BRAKE FAILURE, TRAILER BRAKE FAILURE, ESC FAILURE, DO NOT EXCEED 65MPH WARNING. AFTER SEEING THOSE I APPLIED THE BRAKE TO STOP AND THE BRAKE PEDAL WENT TO FLOOR LEAVING THE TRUCK WITHOUT ANY TYPE OF BRAKING POWER WHAT SO EVER. AFTER COASTING TO A STOP I SHUT THE TRUCK OFF RESTARTED IT AND THE CHECK ENGINE ICON WAS ON. THE BRAKES DID WORK AFTER THE TRUCK WAS SHUT OFF AND RESTARTED.

SERVICE BRAKES
AFTER HAVING A RECALL ISSUE FIXED ON THE ABS BRAKING SYSTEM OF MY TRUCK, I REMOTED STARTED IT FROM GM'S ONSTAR APP, WHICH CAUSED THE DASHBOARD TO LIGHT UP LIKE A CHRISTMAS TREE AND GIVE A NUMBER OF ERRORS, INCLUDING A SOLID ENGINE LIGHT. GM ONSTAR DIAGNOSIS IDENTIFIED THAT THERE IS NOW ANOTHER ISSUE IN THE ABS BRAKING SYSTEM. THERE HAS BEEN NO MECHANICAL FAILURE AT THIS POINT, BUT I AM CONCERNED THEIR MAYBE AS OTHERS WITH THIS SAME ISSUE HAVE SEEN MECHANICAL FAILURE.
