2017 GMC Terrain UNKNOWN OR OTHER

In September of 2022 my gmc automatically shut off right in the middle of traffic on a Friday night. No warring, no lights to indicate that something was wrong with my vehicle. I took it to a mechanic shop and they said nothing was wrong and they did a diagnostic test on the car and no codes popped up. A week later my engine light came on. And my car died again. Thankfully, I had an extended warranty on my car and took to another mechanic shop. It turns out the timing changes on my car needed to be replaced. Fast forward to today Jan 22,2024. I smelled burning oil every time I would drive the vehicle. The rear main seal and PCV was leaking in between my engine and transmission. I lost 5 quarts of oil between Wednesday and Sunday. My oil light never came in. Thankfully, my engine didn’t lock up. It is currently in the shop getting repaired. My car is still under an extended warranty.

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.

VEHICLE WAS PARKED WITH THE MOTOR RUNNING. REACHED OVER FROM THE PASSENGER SEAT AND TURNED THE MOTOR OFF. VEHICLE BEGAN TO ROLL BACKWARDS. WAS ABLE TO TURN VEHICLE BUT UNFORTUNATELY BACKED INTO THE DOOR OF A PARKED TRUCK TURNING THE IGNITION OFF SHOULDN'T START THE VEHICLE TO MOVE.

I WAS DRIVING AND INSIDE ALARM CAME ON SOUNDED LIKE A FIRE ALARM. HOWEVER NO LIGHTS IN THE CAR CAME ON INDICATION SOMETHING WAS WRONG, TIRE PRESSURE WAS GOOD, EVERYTHING AS FAR AS MY EYES COULD SEE IT WAS FINE EXCEPT THAT AN ALARM KEPT GOING OFF COMING THRU THE SPEAKERS. I PULLED OVER GOT OUT LOOKED AROUND THE VEHICLE. NOTHING! MADE SURE ALL DOORS WHERE LOCKED AND EVERYTHING GOOD ALARM STILL GOING OFF. NOT THE CAR THEFT ALARM AN INTERNAL ALARM THRU THE SPEAKERS OF THE CAR. PLEASE HELP AS I AM SCARED TO DRIVE MY VEHICLE BECAUSE MAYBE IT WAS TRYING TO TELL ME SOMETHING IS WRONG. IT EVENTUALLY WENT OFF AND I PULLED OFF VEHICLE DROVE FINE.

I'VE HAD MY TERRAIN FOR 3 MONTHS. CAR HAD 3400 MILES AT THE TIME OF THE ISSUE. BACKED OUT OF MY DRIVEWAY, PUT THE CAR IN DRIVE AND IT WOULDN'T GO. THE CAR WOULD REV UP BUT WOULDN'T MOVE FORWARD. HAD TO PUT THE CAR IN NEUTRAL AND PUSH OUT OF THE MIDDLE OF THE STREET. CAR WAS STRANDED IN THE STREET FOR THREE DAYS DUE TO THE DEALERSHIP SERVICE DEPARTMENT BEING CLOSED. EACH DAY I TRIED TO PUT THE CAR IN DRIVE AND IT STILL WOULDN'T GO WHEN PUT IN DRIVE OR MANUAL ONLY REVERSE. CAR WAS TOWED TO THE DEALERSHIP AND SAT FOR ANOTHER DAY BEFORE THE DEALERSHIP COULD GET TO IT. DEALERSHIP CALLED AND THE CAR WOULD DRIVE WITH NO ISSUE. ASKED IF SOMETHING COULD HAVE SHIFTED WHEN THE CAR WAS TOWED SO THEY KEPT THE CAR ONE MORE DAY TO RUN SOME DIAGNOSTIC TESTS WHICH STILL RESULTED IN NOTHING BEING FOUND.

OUR NEW TERRAIN HAS "VEHICLE IN FRONT" VISUAL WARNING SYSTEMS. WE WERE FOLLOWING A TANKER TYPE SEMI ON THE INTERSTATE AND PULLED ALL THE WAY UP BEHIND THE TANKER SEMI (WITHIN 25 FT) AND THE VEHICLE IN FRONT LIGHT NEVER CAME ON. WE TESTED THIS ON ALL TYPES OF CARS AND TRUCKS AS WELL AS STANDARD BOX TYPE SEMI AND IT WORKED PERFECTLY. I HAVE PICTURES OF THE REAR END OF THE TANKER SEMI IN WHICH IT DID NOT DETECT AT ALL.

SIDE BLIND SPOT ALERT COMES ON AND OFF WHEN RAINING OR SNOWING WITH NOTHING THERE, THEY SHOULD TELL YOU THIS WILL HAPPEN BEFORE YOU PAY EXTRA FOR THIS PACKAGE, HOW DO YOU KNOW IF IT WORKS OR NOT WHEN DRIVING DOWN HIGHWAY
