| Apr 2019 | ELECTRICAL SYSTEM,SERVICE BRAKES,FUEL/PROPULSION SYSTEM | 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. THANK YOU, [XXX] INFORMATION REDACTED PURSUANT TO THE FREEDOM OF INFORMATION ACT (FOIA), 5 U.S.C. 552(B)(6). *CC *TR | Crash: No Fire: No | 17,300 |
| Apr 2019 | ENGINE | 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". | Crash: No Fire: No | 10,000 |
| Mar 2019 | SERVICE BRAKES | 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. | Crash: No Fire: No | 161 |
| Feb 2019 | UNKNOWN OR OTHER | 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. | Crash: No Fire: No | 100 |
| Jan 2019 | ELECTRICAL SYSTEM,UNKNOWN OR OTHER | 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. | Crash: No Fire: No | 100 |
| Jan 2019 | ELECTRICAL SYSTEM | WHEN THE TEMPERATURE DROPS BELOW ABOUT 20 DEGREES (FAHRENHEIT) THE CENTER INSTRUMENT CLUSTER STARTS DISPLAYING EMERGENCY CODES THAT REQUIRE CONSTANT CLEARING, ONLY TO HAVE THE ERROR CODES REAPPEAR. THE SAME THING HAPPENS ON THE INFOTAINMENT HEAD UNIT IN THE CENTER STACK -- IT FLASHES, RESETS, CUTS THE SOUND IN AND OUT AND DISPLAYS TRAILERING CHECKLISTS. ALL OF THIS IS IMMENSELY DISTRACTING TO THE DRIVER AND CREATES A SAFETY HAZARD. I'VE HAD IT SERVICED AND HAVE BEEN TOLD GM ENGINEERS ARE AWARE OF THE ISSUE (ITS COMMON ON 2019 SIERRA AND SILVERADO 1500 TRUCKS) BUT HAVE BEEN UNABLE TO FIND A SOLUTION. I HAVE VIDEO OF BOTH TYPES OF ERRORS. | Crash: No Fire: No | 2,300 |

ALERTS HAPPENED EVER 2-4 SECONDS WITH SCREEN FLASHES EACH TIME. VERY DISTRACTING IN THE DARK WHICH MAKES IT DIFFICULT TO PAY ATTENTION TO THE ROAD. ALMOST REAR ENDED ANOTHER VEHICLE DUE TO THIS ISSUES. | Crash: No Fire: No | 1,000 |
