2019 GMC SIERRA 1500 Complaints

GPS INFOTAINMENT SCREEN IS TO BRIGHT AT NIGHT AND THERE IS MINIMAL ADJUSTMENT THAT ALSO DIMS THE INSTRUMENT CLUSTER SO THAT YOU CAN'T SEE IT AND CONTROLS. AFTER DIMMING EVERYTHING TOGETHER INSTRUMENT CLUSTER AND THE GPS SCREEN AND PLACING THE VEHICLE INTO REVERSE THE SCREEN GOES INTO FULL BRIGHTNESS IF YOU PUT IT IN DRIVE THE SCREEN GOES TO THE FRONT CAMERA AND IS DIM LIKE IT WAS BEFORE PLACING IT IN REVERSE. THERE IS NO CONTRAST OR DIM OPTION FOR JUST THE INFOTAINMENT SCREEN. THE ONLY OPTION IS AUOT DAY NIGHT ALL ARE VERY BRIGHT AND DULL GRAY LOOKING LACKING CONTRAST. IT'S VERY DIFFICULT TO DRIVE AT NIGHT WITH THIS SCREEN BLINDING YOU NON STOP THE ONLY THING YOU CAN DO IS PLACE A RAG OVER IT. I CAN'T DRIVE THE TRUCK AT NIGHT IT IS VERY DISTRACTING TO ME AND I DON'T FEEL SAFE.

ON APRIL 21ST A PRESSURIZED LINE LEADING FROM THE ENGINE TO THE ENGINE COOLER FAILED AND THE ENGINE SUFFERED RAPID OIL LOSS LEADING TO ENGINE FAILURE. THIS APPEARS TO BE A FREQUENT ISSUE WITH 2019 SIERRAS AND SILVERADOS (THE NEW BODY STYLE): HTTPS://WWW.GM-TRUCKS.COM/FORUMS/TOPIC/222403-2019-SILVERADO-TRAILBOSS-53L-ENGINE-OIL-COOLER-LINE-FAILURE/ THE TRUCK WAS MOVING AT APPROXIMATELY 35MPH ON A STRAIGHT SURFACE STREET AT THE TIME OF FAILURE. MILEAGE WAS ONLY 5,500 MILES. OTHER IMPACTED OWNERS SEEM TO BELIEVE IT IS A FAILURE OF A POORLY DESIGNED CRIMP CONNECTOR. IT'S BEEN 15 DAYS SINCE THE INCIDENT AND MY VEHICLE ISN'T REPAIRED YET. OTHER OWNERS REPORT WAITING CLOSE TO 30 DAYS FOR GM TO DECIDE HOW TO PROCEED.

TRANSMISSION JERKS INTO GEAR WHEN SLOWING DOWN. WHEN SPEEDING UP TRUCK WILL JERK. SERVICE MANAGER SAID IT WAS NORMAL. TRUCK FEELS LIKE IT THE REAR END FALLS OUT WHEN STOPPING.

FIRST WEEK OF OWNERSHIP I NOTICED THAT THE REAR WINDOW HAD A WATER LEAK BY REAR DRIVER SEAT. WHILE INSPECTING THE LEAK, I NOTICE THAT THE PAINT ON THE REAR BRAKE SPOILER ABOVE THE REAR WINDOW HAD TWO BLACK MARKS. BODY SHOP TECHNICIAN RUBBED HIS FINGERS ON THE SPOTS AND PAINT WAS RUBBING OFF. I STARTED TO RECEIVE 'SERVICE STEERING COLUMN LOCK' MESSAGES INTERMITTENTLY AND REGULARLY DURING STARTUP. HEATING INDICATOR LIGHTS FOR ALL THE SEATS DO NOT LIGHT UP TO INDICATE THEIR SETTINGS. THIS OCCURS WHILE VEHICLE IS STATIONARY OR ON THE ROAD. THE REAR BACKUP CAMERA SCREEN TURNS BLUE AND DISPLAYS 'SERVICE REAR BACKUP CAMERA' WHILE REVERSING AND IT OCCURS OCCASIONALLY.

ON APRIL 2, 2019 I PARKED BREFILY FOR ABOUT 30 MINUTES. UPON RE-ENTERING MY 2019 GMC SIERRA TRUCK WITH APPROXIMATELY 4500 MILES AND STARTING THE ENGINE I IMMEDIATELY RECEIVED MULTIPLE WARNING MESSAGES ON MY DASH PANEL. THEY WERE "SERVICE ESC" "SERVICE TRAILER BRAKE", "BRAKE SYSTEM FAILURE" "STEERING ASSIST REDUCED" AND TO DRIVE NO FASTER THAN 62 MPH. PREVIOUSLY PRIOR TO PARKING I HAD NEVER HAD ANY PROBLEMS WHATSOEVER. I WAS IN A LOCATION WHERE I NEEDED TO GO SO I ATTEMPTED TO DRIVE BUT FOUND QUICKLY THAT THE BRAKE PEDEL WENT ALL THE WAY TO THE FLOOR WITH VERY LIMITED OR BASICALLY NO BRAKING. THE STEERING BECAME VERY DIFFICULT WITH NO APPARENT POWER ASSIST. I DROVE IT APPROXIMATELY TWO MILES AND GOT TO A LOCATION WHERE I COULD PARK. I TURNED THE ENGINE OFF AND BACK ON AND THE PROBLEM DID NOT GO AWAY. I TURNED IT OFF AGAIN AND WAITED A COUPLE OF MINUTES AND THEN HEARD AN AUTOMATED COUPLE OF CLUNK SOUNDS FROM THE FRONT.. I STARTED IT UP AND EVERYTHING WAS OKAY EXCEPT THE CHECK ENGINE LIGHT WAS ON AND STAYED ON THE REST OF EVENING. THE NEXT MORNING THE CHECK ENGINE LIGHT WAS STILL ON HOWEVER ABOUT TWENTY MINUTES LATER I NOTICED IT WAS OFF AND EVERYTHING HAS BEEN FINE SINCE. I HAD PLANNED TO TAKE IT TO THE GMC DEALER HOWEVER WITH NO PROBLEM SHOWING NOW AND FROM PAST EXPERIENCE WITH THE DEALERSHIPS I DECIDED THERE WAS NO NEED TO SCHEDULE AN APPOINTMENT UNTIL THE SYMPTOMS COME BACK. I FOUND ON THE INTERNET LATER THAT THERE ARE NUMEROUS INSTANCES WHERE THIS HAS HAPPENED TO MANY OTHER 2019 GMC SIERRA OWNERS. I FEEL THAT THIS IS A EXTREMELY SERIOUS PROBLEM THAT NEEDS IMMEDIATE ATTENTION ESPECIALLY WITH THE NEAR TOTAL BRAKING SYSTEM FAILURE!

WHILE DRIVING DOWN ROAD, SUDDEN MESSAGE OF "NO OIL PRESSURE, TURN OFF ENGINE IMMEDIATELY". WAS ABLE TO PULL OVER WITH NO POWER (LUCKILY IT WAS SAFE TO DO SO AT THE TIME). LEFT A LARGE PUDDLE OF OIL UNDERNEATH THE FRONT OF THE VEHICLE. ALSO, LEFT LARGE CLOUD OF SMOKE FROM OIL SPLASHING ON HOT COMPONENTS UNDERNEATH VEHICLE (EXHAUST, ETC...) BEHIND ME. VEHICLE WAS UNDRIVEABLE AND HAD TO BE TOWED. LARGE OIL LEAK WAS THE RESULT OF A BURST OIL COOLER LINE. DEALER DID NOT SHOW ME THE FAILED PART. UNABLE TO CONFIRM NATURE OF "BURST".

I AM A HEAVY HIGHWAY CONSTRUCTION INSPECTOR FOR WVDOH AND WHILE WORKING ON I 81 SB IN MARTINSBURG, WV THIS MORNING AROUND 2:00 AM WHILE PERFORMING MY DUTIES I ATTEMPTED TO PULL OUT OF MY LANE CLOSURE INTO TRAFFIC WHEN MY TRUCK LITERALLY GOT STUCK HALFWAY OUT INTO LIVE TRAFFIC. IT WAS AS IF I WAS STOMPING ON THE BRAKES INSTEAD OF GIVING IT GAS. FORTUNATELY I REACTED SWIFTLY AND PUT THE TRUCK IN REVERSE TO BACK INTO MY LANE CLOSURE PREVENTING A COLLISION WITH A TRACTOR TRAILER TRAVELING AT SPEEDS IN EXCESS OF 55 MPH. I WAS LITERALLY SHAKING WHEN I REALIZED HOW CLOSE OF A CALL IT ACTUALLY WAS AND THAT NOT ONLY COULD I OR THE TRUCK DRIVER HAVE BEEN KILLED, BUT SO COULD THE WORKERS ON MY JOB HAVE BEEN INJURED AND/OR KILLED. I HAD TO HAVE MY TRUCK TOWED BACK TO MY FIELD OFFICE. FOR SOME REASON THE TRUCK STARTED DRIVING PROPERLY AGAIN. THERE IS DEFINITELY SOMETHING WRONG AND IT IS EXTREMELY FORTUNATE THAT NO INJURIES OCCURRED ON MY PROJECT. I DID NOTICE A POST ON THIS WEBSITE EXPLAINING THE VERY THING THAT HAPPENED TO ME THIS MORNING. THIS ISSUE MUST BE ADDRESSED IMMEDIATELY BEFORE PEOPLE ARE KILLED.

WHILE DRIVING MY TRUCK APPROXIMATELY 45 MPH ON A STREET, I HEARD THE VEHICLE NOTIFICATION ALARM SOUND, I LOOKED DOWN AT THE DASH AND HAD SEVERAL WARNING LIGHTS ILLUMINATED:I HAD FOUR MESSAGES: SERVICE ESC SERVICE TRAILER BRAKE BRAKE SYSTEM FAILURE - 62 MPH TOP SPEED STEERING ASSIST REDUCED DRIVE WITH CARE LIGHTS ON DASH THAT WERE ILLUMINATED ABS CHECK ENGINE BRAKE TRACTION CONTROL BEFORE I COULD READ EACH WARNING LIGHT, A RED STOP LIGHT WAS APPROACHING. I WAS AT THAT TIME I PRESSED ON THE BRAKES AND REALIZED THAT MY BRAKES WERE EXTREMELY SPONGEY. I FIGURED I ONLY HAD ABOUT 10% BRAKING POWER. WITH MY TWO YEAR OLD IN THE BACK SEAT, I PUSHED AS HARD AS I COULD TO STOP MY TRUCK. LUCKILY, BY THE GRACE OF GOD, I WAS ABLE TO STOP MY TRUCK WITHOUT REAR ENDING THE CAR IN FRONT OF ME. MY TRUCK WAS THEN TOWED TO THE DEALERSHIP. I BOUGHT THE TRUCK 5 DAYS PRIOR. MY TRUCK HAS APPROXIMATELY 161 MILES ON IT. THE DEALER TOLD ME THE NEXT DAY I NEEDED A NEW MASTER CYLINDER AND HYDRO BOOST. PROBABLY THE ABSOLUTE WORSE COMPONENT TO FAIL ON THE DRIVER WHILE THE VEHICLE IS IN MOTION.

MY 2018 GMC SIERRA HAS VIBRATION AT HIGHWAY SPEEDS 60-75 MPH. AFTER SEVERAL HOURS OF DRIVING THE VIBRATION CAN BE FELT AS LOW A 20 MPH AND UP TO 75 MPH.

WHEN I AM DRIVING MY TRUCK, I WILL GET NOTIFICATIONS SAYING THAT THERE IS A TRAILER DISCONNECTION ISSUE WHEN I DON'T EVEN HAVE A TRAILER CONNECTED. IT ALSO FLASHES AN ALERT SAYING THAT THE LANE DEPARTURE SYSTEM AND PEDESTRIAN SENSOR ARE BEING EFFECTED. AS THIS IS GOING ON, THE INFOTAINMENT SCREEN FLASHES ON AND OFF AS WELL WHICH IS VERY DISTRACTING. THEY HAVE CONTINUED TO COME ON IN COLD WEATHER AFTER I HAVE TAKEN IT TO THE DEALERSHIP TO BE LOOKED AT. I DON'T KNOW IF THIS IS A HARDWARE OR SOFTWARE PROBLEM BUT IT NEEDS TO BE ADDRESSED BECAUSE IT BECOMES BOTH A LARGE NUISANCE AND SAFETY HAZARDS WHEN YOU HAVE ERRORS MESSAGES AND LIGHTS FLASHING WHILE YOU'RE DRIVING.
