2018 GMC TERRAIN Complaints

MY AUTO STARTED LEAKING SOME KIND OF OIL.NOT SURE WHAT KIND BUT I CAN SEE ACCUMULATION ON DRIVEWAY CONCRETE PAD. HAD MOTOR OIL & FILTER CHANGED IN CASE IT WAS A O-RING OR NOT TIGHT ENOUGH. IT CONTINUES TO LEAK.

MY 2018 GMC TERRAIN SLE HAS 41668 MILES AND HAS BEEN SERVICED AS NEEDED. ANYHOW, SOMETIMES WHEN I AM DRIVING, I CAN FEEL THE POWER TRAIN STALL OUT WHEN DRIVING INTERMITTENTLY. THIS CONCERNS ME AS A SINGLE PARENT WITH A 10 YEAR OLD CHILD THAT GOES EVERYWHERE WITH ME. I JUST WANT MY VEHICLE TO BE SAFE.

BRAKING ASSIST MESSAGE IS APPEARING AND BRAKING IS EXTREMELY HARD AT LOW SPEED. YOU HAVE TO PUSH DOWN HARD ON BRAKE TO GET CAR TO STOP.

TL* THE CONTACT OWNS A 2018 GMC TERRAIN. THE CONTACT STATED THAT WHILE DRIVING AT VARIOUS SPEEDS, THE VEHICLE STALLED INTERMITTENTLY WITH THE CHECK ENGINE WARNING LIGHT ILLUMINATED. THE CONTACT HAD TAKEN THE VEHICLE TO HILLSDALE BUICK GMC (99 W CARLETON RD, M-99, HILLSDALE, MI 49242) ON MULTIPLE OCCASIONS TO HAVE MULTIPLE REPAIRS PERFORMED ON THE VEHICLE INCLUDING THE REPLACEMENT OF THE ECM, SEVERAL FUEL INJECTORS, AND MULTIPLE COMPUTER UPDATES PERFORMED HOWEVER, THE FAILURE PERSISTED AFTER EACH VISIT. THE MANUFACTURER WAS NOTIFIED OF THE FAILURE AND REFERRED THE CONTACT TO NHTSA FOR ASSISTANCE. THE VEHICLE WAS NOT REPAIRED. THE FAILURE MILEAGE WAS APPROXIMATELY 90,000.

WHEN RESTARTING AFTER VEHICLE "AUTO STOP" I AM GETTING "SERVICE BRAKE ASSIST" AND OCCASIONALLY "SERVICE ESC" WARNINGS. THESE WARNINGS WERE ASSOCIATED WITH BRAKE FAILURE IN GM SUV'S AND PICKUPS AND WERE SUBJECT TO A RECALL. NO SUCH RECALL EXISTS FOR THE TERRAIN. I HAVEN'T YET EXPERIENCED A BRAKE FAILURE BUT GM SEEMS TO WANT TO WAIT UNTIL I DO TO FIX THE PROBLEM.

MY 2018 GMC TERRAIN BRAKES DID NOT WORK WHEN COMING TO A STOP AT STOP LIGHTS WHICH CAUSED ME TO REAR END THE CAR IN FRONT OF ME. THERE WAS NO WARNING ON MY SUV NOR DID I RECEIVE A RECALL ON THIS MATTER. THIS HAPPENED TWICE TO ME IN THIS SAME VEHICLE WHERE THE BRAKES DID NOT RESPOND AT A LOW SPEED CAUSING AN ACCIDENT. THIS ACCIDENT JUST HAPPENED TO CAUSE DAMAGE TO MY VEHICLE AND THE CAR IN FRONT OF ME.

THE SERVICE STABILITRAK LIGHT CONTINUES TO COME ON. WHEN IT DOES, ALMOST ALL OF THE LIGHTS ON THE DASH LIGHT UP AND THE CAR PUTS ITSELF IN NEUTRAL AND SHUTS OFF. THIS HAS HAPPENED 5 TIMES IN THE PAST TWO WEEKS. TWICE WITH MY [XXX] IN THE CAR. PARTS OF THIS DOCUMENT HAVE BEEN REDACTED TO PROTECT PERSONALLY IDENTIFIABLE INFORMATION PURSUANT TO THE FREEDOM OF INFORMATION ACT (FOIA), 5 U.S.C. 552(B)(6). THE CAR WAS PURCHASED 12/23/2020 AND IT FIRST SHUT OFF WITH THE SERVICE STABILITRAK WARNING 12/31/2020. I'VE TAKEN IT TO THE DEALERSHIP FOR REPAIR. THEY REPLACED THE FRONT RIGHT WHEEL SENSOR TODAY AND IMMEDIATELY AFTER LEAVING THEIR LOT, IT SHUT OFF TWICE. I DID A SEARCH ON THE VIN AND FOUND THAT THIS VEHICLE HAD ISSUES AT 11K MILES AND 27K MILES. NOW AGAIN AT 55K MILES. THE CAR JUST SHUTS ITSELF OFF WHILE DRIVING. FIRST TIME IT HAPPENED, I WAS ROUNDING A CORNER IN HIGH TRAFFIC AND IN MID TURN, THE CAR SHUT OFF. I WAS ALMOST HIT BY SEVERAL CARS. THIS VEHICLE IS DANGEROUS. IT HAPPENED ONCE WHILE ON THE HIGHWAY WITH MY 15 MONTH OLD IN THE CAR AND TODAY IT HAPPENED TWICE WITH HER IN THE CAR.

CAR SHUTS OFF COMPLETELY AT A STOP AND NO POWER AT ALL UNTILL IT IS JUMP STARTED.
