VEHICLE SINCE PURCHASE SHOWS NO SIGNS OF LEAK BUT GOES THROUGH OIL AT ABOUT 1 QUART EVERY 1000 MILES MAX. CHECK ENGINE LIGHT ALWAYS ON, SENSORS INDICATE POSSIBLE FAULTY PISTON RINGS. ALL WERE PROBLEMS IN LATER MODEL GMC TERRAINS. WHEN LOW ON OIL WHILE DRIVING AND STATIONARY ALL LIGHTS WILL LIGHT UP AND ENGINE WILL GO INTO REDUCED POWER MODE SAYING TO SERVICE STABILITRACK. CAR WILL NOT GO ABOVE 10 MPH WHEN IN THIS MODE, SOMETIMES UNABLE TO MOVE AT ALL. GOES AWAY AFTER MORE OIL ADDED. GMC TERRAIN HAD RECALLS ON YEARS 2010-2013 FOR ALL ENGINE FAILURE PROBLEMS/REPAIRS DUE TO FAULTY PISTON RINGS/OIL CONSUMPTION ISSUES. NUMEROUS 2014-2016 GMC TerrainS HAVE CLAIMS OF THE REDUCED POWER/STABILITRACK PROBLEM WITH NO SOLUTION, I BELIEVE BOTH PROBLEMS ARE DIRECTLY RELATED.

I place vehicle in park and the computer does not recognize so the bell comes on. I have to go in and out of park several times before it engages. This occurs when i am turning the engine off, i first place in park then push the ignition to shut off. We had a prior issue where the emergency brake was on, auto backed in a driveway with slight incline, and when we tried to disengage it was simply stuck, we called to tow the care; once driver arrived we went through the release one more time and it finally released. Since that time, i never use the parking brake. That occurred approximately 9/20/2018..

  • Date complaint filed: 13:24 Feb-24, 2021

Dangerous visibility hazard when backing up vehicle at night. Infotainment screen switches to "full brightness" when backup camera is activated, resulting in blinding light to driver. Driver can not backup safely without physically covering the screen to regain visibility. Screen brightness reflects off all 4 windows, windshield and back glass. Side mirrors are unusable in this condition. There was a fix for this issue on previous gm models, (prior to 2018), however no fix for 2019 - present

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.
