2015 GMC SIERRA 1500 Complaints

VEHICLE IS SHUTTING OFF AT ANY GIVEN SPEED, IE. 35 MPH IN TOWN OR 70 MPH ON A HIGHWAY WITH ONCOMING TRAFFIC. WHEN VEHICLE SHUTS OFF, LOSS OF ALL CONTROL OF THE VEHICLE TAKES PLACE. NO BRAKES, NO STEERING, NOTHING UNTIL THE VEHICLE RANDOMLY TURNS BACK ON. THIS IS NOT A CONSISTENT OCCURRENCE TO KNOW WHEN IT IS GOING TO HAPPEN OR BE PREPARED FOR IT TO HAPPEN. I WATCHED MY HUSBAND SHOOT ACROSS THE ROAD INTO THE OTHER LANE AND ALMOST PUT THE VEHICLE OVER A BANK ONE NIGHT WHEN IT HAPPENED. THIS HAS BEEN AN ISSUE SINCE JANUARY 2018 FOR US, WE HAVE TAKEN IT TO THE DEALER WHERE IT WAS PURCHASED MULTIPLE TIMES FOR THEM TO TELL US THEY CAN'T DUPLICATE THE ISSUE AND NOTHING IS COMING UP IN THEIR SYSTEM FOR AN ERROR CODE. IT HAS CAUSED A MAJOR INCONVENIENCE FOR MY FAMILY, AS WE DON'T DARE PUT OUR CHILDREN IN THE TRUCK LEAVING THE RESPONSIBILITY SOLELY ON ONE PARENT TO TRANSPORT THE KIDS TO AND FROM DAYCARE. I WORRY FOR THE SAFETY OF MY HUSBAND ON A DAILY BASIS.

THE VEHICLE WAS REPAIRED, BUT THE DEALER WAS NOT SURE IF IT WOULD REMEDY THE FAILURE. THE MANUFACTURER WAS NOT MADE AWARE OF THE FAILURE. THE FAILURE MILEAGE WAS 29,597.

WHILE DRIVING AT HIGHWAY SPEED, I ENTERED AN OFF RAMP TO FIND NO POWER ASSIST TO MY BRAKES. THE PEDAL WAS EXTREMELY STIFF. I CAME VERY CLOSE TO HAVING A COLLISION WITH THE CAR IN FRONT OF ME. I CONTACTED MY MECHANIC IMMEDIATELY, HE CHECKED IT OUT AND IT APPEARS THE VACUUM PUMP HAS FAILED WITHOUT WARNING. I HAVE OWNED THIS VEHICLE SINCE NEW AND HAVE HAD NO PROBLEMS WITH IT UNTIL THIS ISSUE.

THIS POST IS ABOUT MAKING THE PUBLIC AWARE OF A POTENTIAL PROBLEM. ALTHOUGH THE MANUFACTURER DID NOT STEP UP AND DO THE RIGHT THING, I'M CONCERNED OTHERS MAY HAVE DEALT WITH THIS PROBLEM OR IT MAY HAPPEN IN THE FUTURE. ON AUGUST 29, 2018, MY TRUCK WAS PARKED ON MY DRIVEWAY BY 4PM AFTER RUNNING ERRANDS FOR A COUPLE OF HOURS. AT 6PM MY HUSBAND WENT OUT TO GET SOMETHING OUT OF IT AND SAW IT HAD CAUGHT ON FIRE. NOTHING WAS LEFT PLUGGED IN AND THERE WAS NOTHING FLAMMABLE IN THE TRUCK. THE FIRE DEPT WAS CALLED AND UPON INSPECTION STATED THE FIRE HAD STARTED IN THE CENTER CONSOLE AND SPREAD TO THE FRONT PASSENGER SEAT. THE CAUSE OF THE FIRE LOOK TO BE WIRING THAT OVERHEATED INSIDE THE CONSOLE WHERE THE WIRING CONNECTED TO 2 USB PORTS. GM INSPECTED THE DAMAGE AND FOUND THERE WAS NOT A MANUFACTURER DEFECT AND THE CAUSE OF THE FIRE WAS FROM AN EXTERNAL SOURCE. IRONICALLY, THEIR 3RD PARTY "EXPERT" FIRE INVESTIGATOR WAS NOT AWARE THERE WAS A WIRING HARNESS LOCATED BEHIND THE USB PORTS AND HAD TO BE SHOWN THEIR LOCATION. MY INSURANCE COMPANY IS NOW INVESTIGATING THE INCIDENT. I'M ASKING THEM TO LOOK INTO THE 12V POWER OUTLET POSSIBLY OVERHEATING AS I KNOW OF SOMEONE WHO HAD THEIRS OVERHEAT IN THEIR 2018 CHEVY SILVERADO. THE DAY AFTER THE FIRE I SENT PHOTOS TO THEM AND THEY COULD NOT BELIEVE THE DAMAGE. WHEN I TOLD THEM THE OUTCOME OF GM'S INVESTIGATION THEY WERE DUMBFOUNDED. I'M FORTUNATE NO ONE WAS HURT, BUT AM AFRAID THIS MAY HAPPEN TO SOMEONE ELSE. I MADE A 40K + INVESTMENT WITH GM AND LITERALLY "WAS BURNED". I WANT OTHER TO BE AWARE OF THE POTENTIAL FIRE DANGER. I DID EXPECT GM TO STEP UP AND TAKE CARE OF THEIR LOYAL CUSTOMER (I'VE BOUGHT 8 GM VEHICLES), BUT IT APPEARS THE ALMIGHTY DOLLAR WON OUT. THANKFULLY, IN MY CASE, NO ONE WAS HURT.

I WAS BACKING UP AND THE BRAKE PEDAL GOT HARD AND WOULD NOT STOP THE TRUCK. I TRIED TO GO FORWARD AND THE SAME THING HAPPEN.

WHEN MAKING SLIGHT LEFT TURNS, THE TRUCK WOULD FLASH STABILITRAK ON THE DISPLAY AND THE STEERING WHEEL WOULD AUTOMATICALLY PULL OUT OF MY HANDS AND MAKE THE WHEELS STRAIGHTEN UP. THE RADIO WOULD THEN GO DEAD AND THEN 5 TO 10 SECONDS LATER THE ENTIRE TRUCK WOULD TURN OFF. THIS HAPPENED WHILE DRIVING DOWN THE ROAD. THIS HAPPENED ON 2 SEPARATE OCCASIONS WITH NO OTHER WARNINGS. I CONTACTED GMC AND THEY HAVE NOT GIVEN ME ANY TYPE OF ANSWER OR ASSISTANCE.
