OnStar - I've had OnStar for several years and paid the bill annually by check. The company never sent a renewal bill this year. I contacted them via phone on 1-23-2021, 2-8-2021, 2-22-2021 and 3-9-2021. I used phone numbers 1-866-891-1233, 1-866-579-0028, and the OnStar button to talk to representatives. I also wrote letters to OnStar dated March 9 and March 27, 2021 without results. I had a confirmation # CN4175174. I never received a bill and now the safety device is cut off in my car.

PURCHASED GMC 2017 TERRAIN 1 MONTH AGO TODAY. THE FIRST WEEK I HAD IT THE ENGINE KEPT STALLING WHILE IDLING. I TOOK IT TO THE DEALERSHIP FOR THEM TO FIX. I GOT IT BACK AND IT SEEMED TO RUN HARD. 3 DAYS LATER I FOUND THAT NOT ONE BUT BOTH KEY FOBS WOULD NOT WORK. THE BATTERY IS BRAND NEW. WHEN I SPOKE TO SERVICE MAN AT DEALERSHIP, HE STATED THAT ONE FOB WAS FAULTY AND THEY WOULD ORDER A NEW ONE. I HAVEN'T HEARD BACK FROM THEM...TODAY I GOT INTO A FRONT END COLLISION WHERE THE AIR BAGS DID NOT DEPLOY CAUSING ME INJURY. ONLY AFTER THE FACT DID THE ALARM SOUND AND DASH MESSAGE CAME ON STATING SERVICE AIRBAG. THE FOUR WAY LIGHTS WOULD NOT STAY ON AND THE INTERIOR LIGHTS WOULD NOT TURN OFF. AND THERE WAS A SMELL OF SOMETHING BURNING.. NO RETURN CALL FROM GMC.

MY CHECK ENGINE LIGHT CAME ON ALONG WITH A A MESSAGE THAT STATES 'REDUCED ENGINE POWER' AND A MESSAGE READING 'SERVICE STABILITREK WHEN I WAS DRIVING ON THE HIGHWAY AT 70 MPH. THIS CREATED SUDDENLY JERKING AND SLOW ACCELERATION SO THAT I HAD TO PULL OFF THE ROAD. I FOUND A FORUM AT [XXX] THAT REVEALS THAT THIS HAS BEEN AN ISSUE WITH GMC MODES AT LEAST AS LONG AS 2011. THE DURATION FOR WHICH THIS HAS BEEN A PROBLEM WITH GMC MODELS, AND THE FACT THAT STABILITREK IS AN INTEGRAL SAFETY FEATURE OF THE VEHICLE IN AVOIDING ACCIDENTS SEEMS TO MERIT A RECALL. 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).

I AM THE OWNER OF A 2017 GMC TERRAIN. YESTERDAY, I WAS INVOLVED IN A CAR ACCIDENT IN THIS VEHICLE. SOME PERSON PULLED OUT IN FRONT OF ME AND I SLAMMED ON MY BRAKES TO AVOID A CAR ACCIDENT. HIS VEHICLE CONTINUED THROUGH AN INTERSECTION IN WHICH HE DID NOT HAVE THE RIGHT AWAY CAUSING ME TO HIT THE FRONT END OF HIS TRUCK. AS THE DRIVER STATES HE DID NOT SEE ME, I CAN CONFIRM I SLAMMED ON MY BRAKES, WHICH ACTED AS THEY COULDN'T STOP. IT FELT AS THE BRAKES WERE NONEXISTENT. THIS WAS AN EXTREMELY TERRIFYING MOMENT, AS I WAS GOING 45MPH (PER THE SPEED LIMIT). AS I HAD READ EARLIER, THE 2018 TERRAINS ALSO SEEM TO HAVE THE SAME PROBLEM.

THEY HIT THE FRONT DRIVERS END OF MY CAR WHICH MADE MY CAR SPIN OUT. THE AIRBAGS DID NOT DEPLOY. THE WHOLE FRONT END OF MY CAR WAS RUINED.

AT AROUND 20 MILES PER HOUR, WHILE ACCELERATING, ALL TORQUE IS LOST AND THE VEHICLE ENGINE REVS HIGH. IT TAKES A FEW SECONDS, THEN THE TRANSMISSION FINALLY SHIFTS INTO THE NEXT GEAR. THIS CAUSES A BIG JOLT. IT IS DANGEROUS, ALL POWER IS LOST, THEN SUDDENLY TOO MUCH POWER IS APPLIED. THIS HAS HAPPENED SINCE I PURCHASED THE VEHICLE. I HAVE TAKEN IT TO THE DEALERSHIP. THEY WON'T DO ANYTHING ABOUT IT. THE VEHICLE NOW HAS 40,502 MILES.
