IT IS VERY HARD TO EVEN SEE THE SIDE MIRRORS DUE TO THE BLINDING BRIGHTNESS OF THE DASH DISPLAY. THERE NEEDS TO BE A FIX TO THIS PROBLEM AS IT MAKES BACKING UP AT NIGHT VERY CHALLENGING. *TR

WHEN I WAS AT A STOP LIGHT ON A CITY STREET AND I PRESSED THE GAS PEDAL, THE BRAKES LOCKED ITSELF AND I COULD ONLY GO 5MPH. THIS IS THE FOURTH TIME IT HAS HAPPENED.

TL* THE CONTACT OWNS A 2019 GMC SIERRA 1500. THE CONTACT STATED THAT WHILE DRIVING AT 75 MPH, THE STEERING WHEEL CEASED WITH SEVERAL UNKNOWN WARNING LIGHTS ILLUMINATED. THE CONTACT COASTED TO THE SIDE OF THE ROADWAY AND TURNED OFF THE VEHICLE. THE VEHICLE WAS RESTARTED HOWEVER, THE FAILURE RECURRED.

DRIVING MY 2019 SIERRA ON A SLIGHTLY SNOW COVERED ROAD APPLIED BRAKES AND TRUCK PULLED TO THE RIGHT AND ANTILOCK BRAKES NEVER WORKED CAUSING ME TO HIT GUARD RAIL. CALLED INSURANCE TALKED WITH DEALER ABOUT WHAT HAPPENED THEY SAID TO CONTACT GM CUSTOMER SERVICE. HAD MY WRECKED TRUCK FIXED AND WHEN GM GOT BACK TO ME THEY SAID THERE WAS NOTHING ELSE THEY COULD DO BECAUSE I CONTACTED MY INSURANCE INSTEAD OF DEALERSHIP???? NOW I HAVE RECEIVED ANOTHER RECALL NOTICE TELLING ME MY BRAKES ARE NOT RESPONDING PROPERLY. GUESS I NEED A LAWYER I DON'T KNOW. *TR

WHEN TRUCK IS TURNED ON DASH SAYS SERVICE ESC BRAKE SYSTEM AND SERVICE 4 WHEEL DRIVE WILL NOT DISENGAGE FROM 2 WHEEL DRIVE AND PARKING BRAKE IS ENGAGED AND WILL NOT DISENGAGE AND TRUCK WILL NOT MOVE. INFOTAINMENT SCREEN WILL FREEZE UP AND NOT BE ABLE TO CHANGE RADION NAVIGATION ETC

WHEN I STARTED MY VEHICLE THIS MORNING, I GOT A WARNING OF BRAKE FAILURE THAT CAME UP ON MY DIC; THIS HAS BEEN HAPPENING A LOT. I JUST TOOK THE TRUCK IN LAST WEEK FOR THE 4TH TIME AND THEY DID ANOTHER UPDATE DUE TO THE LAST RECALL THAT WAS PUT OUT BY GM. NOTHING SEEMS TO BE WORKING WITH THIS BRAKE ISSUE. THE BRAKE PEDAL AT TIMES SEEMS TO HAVE DIFFICULTY WHEN I'M STARTING THE TRUCK. I DID NOT USE MY REMOTE START ON ANY OF THE ISSUES I'M HAVING.THE TRUCK WAS PARKED IN MY DRIVE WAY YET IT'S ALSO HAPPENING AT VARIOUS PLACES AROUND TOWN AS WELL. *TR

AT AROUND 1500 MILES MY TRUCK HAD A ROTATIONAL NOISE WHICH LED INTO CLICKING THE GRINDING AND SQUEALING, THEY CHANGED OUT THE FRONT AXLE AND ALL NEW BRAKES AND ROTORS ALONG WITH A BRAKING SOFTWARE UPDATE. THEY ASSURED ME I SHOULD NOT HAVE ANY MORE ISSUES. NOW AT 4,300 MILES I'M STARTING TO HAVE ROTATIONAL NOISE AGAIN AFTER DRIVING ABOUT 1 HOUR, OF COURSE THEY CANT DUPLICATE NOISE. THE TRUCK HAS HAD 5 RECALLS AND ALSO A 4WD PUMP DEFECTIVE ALL WITH 4,300 MILES. I AM FEARFUL THAT THE BRAKES WILL FAIL

SERVICE ESC WARNING ON DASH SERVICE TRAILER BRAKE ON DASH BRAKE SYSTEM FAILURE - 62 MPH TOP SPEED WARNING ON DASH STEERING ASSIST REDUCED DRIVE WITH CARE ON DASH RESTARTED TRUCK AND CHECK ENGINE LIGHT CAME ON

A BLUE SCREEN WITH THE "SERVICE REAR VISION SYSTEM" APPEARED INTERMITTENTLY WHEN I PUT MY TRUCK IN REVERSE. AT FIRST IT WOULD GO AWAY ONCE THE TRUCK HAD RESTARTED. I HAD THE DEALER SERVICE DEPARTMENT CHECK IT OUT BUT THEY SAID THEY COULDN'T REPLICATE IT. THE CAMERA SYSTEM IS NOT ALWAYS IN A BLUE SCREEN REGARDLESS IF I SELECT CAMERA OPTIONS FROM THE INFOTAINMENT MENU OR IF WHEN PUTTING THE TRUCK IN REVERSE. THE DEALER IS CURRENTLY HAVING ISSUES WITH GM PROVIDING THE RIGHT "CALIBRATION" TO FIX THIS ISSUE. WHEN THE CAMERA WAS WORKING, A STRANGE ISSUE OCCURRED IN ADDITION TO BLUE SCREENS. THE RIGHT SIDE CAMERA TURNED OFF AND REMOVED VISIBILITY FROM THAT SIDE OF THE VEHICLE THROUGH THE INFOTAINMENT SCREEN. I FEEL THIS IS A HUGE SAFETY ISSUE SINCE MY VISIBILITY IS SEVERELY HINDERED WHEN REVERSING IN DARK OR DENSE CONDITIONS.

AFTER SHUTTING VEHICLE OFF, THERE'S LOUD NOISES COMING FROM BEHIND THE STEERING WHEEL THAT SOUNDS LIKE RELAYS.

TL* THE CONTACT OWNS A 2019 GMC SIERRA 1500. WHILE DRIVING IN THE SNOW THE LED HEADLAMP COVERS BECAME COVERED WITH SNOW WHICH DIMINISHED THE PROJECTION OF THE HEADLAMP BEAM. THE CONTACT STATED THAT THE BEAM PROVIDED WAS INADEQUATE FOR SAFE DRIVING. THERE WERE NO WARNING LIGHTS ILLUMINATED. THE CONTACT CALLED KING BUICK GMC LOCATED AT (4175 BYRD DR, LOVELAND, CO 80538 (970) 667-8905) AND NOTIFIED THE DEALER OF THE FAILURE. THE VEHICLE NOT TAKEN TO BE DIAGNOSED NOR REPAIRED.

TRANSMISSION SLIPPING TURNING CORNERS AT 5 MPH, TRANSMISSION SLIP TAKE OFF AT HILL STOP SIGN, TRANSMISSION HARD SHIFT 2ND TO 3RD GEAR INTERMITTED AND VIBRATION 45 MPH TO 55 MPH

JUST BOUGHT THIS VEHICLE AND TOOK IT TO THE DEALER AND THEY DON`T HAVE AN EXPLANATION BUT THE BACKUP CAMERA MALFUNCTIONS. THIS COULD BE VERY DANGEROUS WITH YOUNG KIDS AND WHEN BACKING UP WHILE PICKING THE KIDS UP FROM SCHOOL AND AT LOCAL GROCERY OR DEPARTMENT STORES.

2019 GMC SIERRA SHIFTS EXTREMELY HARD WHEN SHIFTING FROM 1ST TO 2ND GEAR WHEN ACCELERATING AFTER SITTING IDLE FOR A LONG PERIOD OF TIME. I TOOK THE VEHICLE TO ROMAIN GMC IN EVANSVILLE, IN AND THEY STATED THAT GM SAYS THIS IS HOW THE TRANSMISSION NORMALLY OPERATES. THIS HAS THE POTENTIAL TO BE A SAFETY ISSUES AS THE ENGINE GOES INTO HIGH REVS AND SLAMS INTO GEAR, RISKING LOSING CONTROL OF THE VEHICLE, ESPECIALLY DURING ICY OR SNOWY CONDITIONS. THIS ISSUE OCCURS DAILY, SOMETIME MULTIPLE TIMES A DAY.

MULTIPLE WARNINGS POPPED UP ON THE SCREEN TELLING ME "BRAKE SYSTEM FAILURE" "ECU FAILURE" "TRAILER BRAKE FAILURE" AND "MAX SPEED 62 MPH." AFTER THAT THE BRAKES BECOME ALMOST NON-FUNCTIONAL. I HAD TO STAND ON THE PEDAL WITH BOTH FEET AND WAS UNABLE TO SLOW DOWN ENOUGH (45 MPH TRAFFIC) TO HAD TO GO INTO THE E-LANE TO AVOID AN ACCIDENT. TRUCK ALSO GAVE DTC P25A2. I CAN'T STRESS ENOUGH THAT IT WASN'T JUST DEGRADED BRAKING, IT WAS ALMOST NOTHING AT ALL. IT TOOK NEARLY 1/8TH OF A MILE TO GET IT STOPPED ON A MILD DOWNHILL GRADE.

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.

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

SUNROOF EXPLODED WHILE DRIVING.

DURING NORMAL OPERATION, WHEN PLACING THE VEHICLE IN REVERSE, THE INFOTAINMENT SCREEN INTERMITTENTLY TURNS BLUE, FLASHES, SCROLLS, OR TURNS BLACK. 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.

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

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.

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.

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.

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.

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.

I HAD NO ISSUES WITH MY TRUCK UNTIL I WENT AND HAD THE MOST RECENT RECALL DONE FOR THE BRAKES. I SINCE HAVE HAD BRAKE ISSUES TWICE. ONCE, HOURS AFTER HAVING THE RECALL DONE I GOT IN MY TRUCK AND STARTED IT AND ALL THE DASHBOARD LIGHTS WERE ILLUMINATED AND I HAD TO PUSH THE BRAKE PEDAL TO THE FLOOR AFTER ACCELERATING. THE OTHER INSTANCE WAS A WEEK LATER AFTER REMOTE STARTING MY TRUCK FROM THE PHONE APPLICATION HAD THE SAME SCENARIO PLAY OUT.

TRUCK PARKED IN MORNING, TURNED IT ON AND MULTIPLE WARNINGS CAME ON, SERVICE TRAILER BRAKE SYSTEM,SERVICE ESC,BRAKE SYSTEM FAILURE AT 62MPH,GOT WARNING FROM ONSTAR THAT THERE IS AN ISSUE WITH MY ANTILOCK BRAKING SYSTEM, I TOOK PICTURES OF ERROR BUT ONLY COULD UPLOAD ONE.

THE TRANSMISSION SHIFTS HARD FROM REVERSE TO DRIVE. ALSO FROM 1ST TO 2ND WHEN ACCELERATING AND FROM 2ND TO 1ST WHEN DECELERATING. THE JERK FROM THE HARD SHIFT FEELS LIKE THE VEHICLE HAS JUST BEEN REAR ENDED BY ANOTHER VEHICLE AND HIS LED ME HITTING OBJECTS WITH THE VEHICLE NUMEROUS TIMES. THIS HAS BEEN GOING ON SINCE I PURCHASED THE TRUCK IN AUGUST OF 2019 AND HAS CONTINUED. I'VE TAKEN THE VEHICLE TO THE DEALER WHO HAS EXPLICITLY STATED THAT THE PROTOCOL IS TO NOTATE THE ISSUE ONLY. NO INVESTIGATION BEYOND THAT HAS OR WILL BE PERFORMED.

THEY INVESTIGATED THE ISSUE AND MADE A SOFTWARE UPDATE WORKING DIRECTLY WITH GM, WHICH IS NOW A CURRENT RECALL. THE TRUCK HAS DONE IT AGAIN AS OF TODAY SO THE SW FIX IS OBVIOUSLY NOT CORRECT.

I RECEIVED NOTICE THAT THERE ARE TWO RECALLS OUT FOR MY TRUCK: A BRAKE SYSTEM RECALL AND A FORWARD CAMERA/COLLISION RECALL. HAD BOTH RECALLS PERFORMED AND IMMEDIATELY THE FORWARD CAMERA COLLISION ALERT, LANE KEEP AND INTELLIBEAM SYSTEMS DIDN'T WORK. DELAER INFORMED ME THERE IS A PROBLEM WITH THE UPDATE AND I NEED A NEW CAMERA. THAT IS ON ORDER AND PENDING. MORE IMPORTANTLY, ABOUT 2 DAYS AFTER THE UPDATES THE TRUCK SHOWED ALERTS ABOUT THE BRAKES, TRACTION CONTROL AND STABILITRACK SYSTEMS. UPON DRIVING THE TRUCK THE POWER/VACUUM ASSIST SYSTEM FAILED AND THE BRAKE PEDAL NEARLY WENT TO THE FLOOR BEFORE ENGAGING BRAKES; I COULD BARELY STOP. RETURNED THE TRUCK TO THE DEALER AND WAS TOLD ITS A COMMON ISSUE WITH THE BRAKE RECALL UPDATE (THE TRUCK HAD NO SUCH SYMPTOMS BEFORE THE UPDATE). IF YOU CHECK OUT VARIOUS GM VEHICLE OWNER FORUMS YOU WILL SEE SCORES OF SILVERADO AND SIERRA OWNERS WITH THE SAME TWO ISSUES POST-UPDATE: NO COLLISION CAMERA AND SUDDEN LOSS OF BRAKES. THERE IS A PROBLEM - A VERY DANGEROUS PROBLEM - WITH THESE UPDATES.

AFTER STARTING MY 2019 GMC SIERRA, I RECEIVED A NUMBER OF WARNINGS INCLUDING: 1. SERVICE TRAILER BRAKE SYSTEM 2. STEERING ASSIST IS REDUCED DRIVE WITH CARE 3. SERVICE ESC 4. BRAKE SYSTEM FAILURE 62 MPH TOP SPEED 5. CHECK ENGINE LIGHT AS I STARTED TO DRIVE, I REALIZED I HAD A VERY DIFFICULT TIME STOPPING AS I HAD TO PRESS THE BRAKE VERY HARD. I WAS IN A PARKING LOT AND ONLY GOING 5 - 10 MPH, BUT STILL HAD DIFFICULTY STOPPING. I TOOK THE VEHICLE TO THE DEALERSHIP. THEY INVESTIGATED THE ISSUE AND MADE A SOFTWARE UPDATE WORKING DIRECTLY WITH GM. FIVE DAYS AFTER PICKING MY VEHICLE UP, I RECEIVED A CALL FROM THE DEALERSHIP SAYING THAT GM DOES NOT HAVE A PERMANENT FIX FOR THE ISSUE AND THAT I MAY EXPERIENCE BRAKE FAILURE AGAIN. MY VEHICLE IS BACK AT THE DEALER WITHOUT A SOLUTION OR TIMEFRAME FOR REPAIR.

PURCHASED NEW, DEC 24, 2019. CURRENT ODOMETER 645MILES. THE VEHICLE WAS PARKED FOR ABOUT 15 MINUTES, WHEN I RETURNED TO MY TRUCK AND TURNED IT ON, MULTIPLE WARNING TONES BEGAN TO SOUND AND THE DASHBOARD WAS ILLUMINATED WITH MULTIPLE WARNING LIGHTS (ABS, TRACTION CONTROL, CHECK ENGINE, PARKING BRAKE) AND MESSAGES READING: "BRAKE SYSTEM FAILURE 62MPH TOP SPEED," 'SERVICE TRAILER BRAKE SYSTEM,' 'STEERING ASSIST IS REDUCED DRIVE WITH CARE,' 'SERVICE ESC.' I TURNED THE VEHICLE OFF AND ON MULTIPLE TIMES OVER THE COURSE OF 20 MINUTES, EXITING THE VEHICLE, LOCKING THE DOORS, UNLOCKING THE DOORS, AND STARTING THE PROCESS FROM THE BEGINNING. I DECIDED I WOULDN'T BE DRIVING OVER 62MPH AS I WAS ONLY 2 MILES FROM MY HOME, SO I DECIDED TO BACK OUT AND DRIVE HOME WITH FULL INTENTIONS OF CALLING THE DEALERSHIP IN THE MORNING. WHEN I TRIED TO BACK OUT I REALIZED THAT I HAD ALMOST ZERO BRAKING POWER, HAVING TO ALMOST STAND UP ON THE BRAKE PEDAL TO STOP THE VEHICLE WITHOUT GIVING IT ANY GAS, AND TURNING WAS DIFFICULT (SIMILAR TO MANUAL STEERING IN A VINTAGE VEHICLE). I KNEW DRIVING HOME WOULD NOT BE SAFE. I TURNS THE VEHICLE OFF AND ON ONCE MORE AND ALL THE WARNING MESSAGES AND LIGHTS WERE NO LONGER THERE. THE CHECK ENGINE LIGHT REMAINED ON AND IS STILL ON. I WAS ABLE TO DRIVE HOME AS THOUGH NOTHING HAPPENED, BUT AM FEARFUL THIS WILL HAPPEN WHILE DRIVING DOWN THE ROAD, ESPECIALLY WHILE MY CHILDREN ARE IN THE CAR. I HAVE READ MULTIPLE FORUMS, THIS IS NOT AN ISOLATED INCIDENT, WITH MANY OTHERS EX

CRUISE CONTROL WOULD NOT DISENGAGE WHEN THE BRAKE WAS APPLIED I WAS ON A HIGHWAY TRAVELING 65 MPH. HAD TO TAKE AN EXIT RAMP TO AVOID A COLLISION WITH VEHICLE IN FRONT OF AND BESIDE ME.

DEAR NHTSA, I RECENTLY LEASED A 2019 GMC SIERRA PICKUP TRUCK. THIS TRUCK IS CURRENTLY IN THE SHOP FOR THE 6TH TIME, AND NEITHER GM OR THE LOCAL DEALERSHIP CAN SEEM TO FIX ANYTHING ON THIS TRUCK. MOST RECENTLY, AS YESTERDAY I HAD MY CAR IN FOR THE BRAKING SYSTEM. THE DEALERSHIP CALLED ME AND SAID MY TRUCK WAS FIXED. AS I TURNED MY TRUCK ON, THE BRAKE SYSTEM LIGHT CAME ON. I WAS TOLD BY THE DEALERSHIP TO JUST DRIVE IT AND IT WILL GO AWAY. I DO NOT FEEL THIS IS A GOOD/SAFE PRACTICE AND GM IS NOT HELPING ME TO GET OUT OF THIS UNSAFE TRUCK.

WHEN I TRIED TO DRIVE MY TRUCK I RECEIVED THE BELOW ERROR MESSAGES AND LIGHTS ON MY DASH BOARD: STEERING ASSIST REDUCED DRIVE WITH CARE SERVICE TRAILER BRAKE SERVICE ESC BRAKE SYSTEM FAILURE - 62 MPH TOP SPEED ABS CHECK ENGINE BRAKE TRACTION CONTROL I DROPPED THE TRUCK OFF AT THE GMC DEALER FOR TWO DAYS, I PICKED IT UP AND IT WAS FINE. I WAS TOLD IT WAS A SOFTWARE UPDATE. THEN 7 DAYS LATER I HAD THE SAME ERRORS MESSAGES AND LIGHTS ON MY DASH BOARD. AND THIS TIME IT WAS EXTREMELY HARD TO STOP THE TRUCK. I NEEDED TO PRESS DOWN ALL THE WAY TO STOP THE TRUCK.

I OWN A 2019 GMC SIERRA DENALI 1500 CREW CAB. AFTER STARTING MY VEHICLE AND BEGINNING MY JOURNEY HOME. SEVER WARNING INDICATIONS OF PROBLEMS CAME ON MY DASHBOARD SYSTEM. WHILE DRIVING, THE BRAKE FAILURE INDICATOR ILLUMINATED AND THE VEHICLE WOULD NOT IMMEDIATELY STOP WHEN DEPRESSING THE BRAKE PEDAL. ALSO, SEVERAL WARNING INDICATORS ILLUMINATED, INCLUDING THE POWER STEERING, SERVICE ESC, BRAKE SYSTEM FAILURE 62 MPH TOP SPEED, STEERING ASSIST IS REDUCED DRIVE WITH CARE, SERVICE TRAILER BRAKE SYSTEM, ABS, AND TRAILER TOWING WARNING MESSAGE INDICATING THAT THE VEHICLE WOULD NOT ACCELERATE ABOVE 62 MPH. IN ADDITION, THE STEERING WHEEL BECAME EXTREMELY DIFFICULT TO TURN IN EITHER DIRECTION.
