NHTSA Complaint #11414635 — 2015 GMC TERRAIN

AT ROUGHLY 106500 MILES OUR TERRAIN STARTED 'JUMPING' WHEN STOPPED AT A STOP SIGN. WE BROUGHT IT IN AND OUR OILS WAS LOW EVEN THOUGH WE ARE REGULAR IN OIL CHANGES AND CHECK IT REGULARLY. AFTER A FRESH OIL CHANGE THE DEALER SAID THEY COULDN'T TELL WHERE IT WAS COMING FROM AND TO COME BACK IN 500 MILES TO CHECK IT AGAIN. AT 107000 MILES WE BROUGHT IT BACK IN AS ASKED. THE OIL WAS SLIGHTLY LOW BUT THEY SAID THEY WOULD CALL AFTER TALKING TO THE MECHANIC TO LET US KNOW IF WE SHOULD HAVE CONCERN. SHORTLY AFTER WE DROVE IT TO WORK WITH NO SOUNDS OR MOVEMENT ISSUES BUT AFTER WHEN WE STARTED IT BACK UP IT SOUNDED MADE LOTS OF NOISE. THE NOISE WAS COMING FROM THE ENGINE. WE HAD IT TOWED TO THE DEALER AND THEY SAID THERE WAS A GOOD CHANCE IT WAS THE TIMING CHAIN BECAUSE THEY HAD SEEN IT ON SOME OTHER TERRAINS AS WELL. THEY ANTICIPATED JUST NEEDING TO REDO THE TIMING CHAIN SINCE WE HADN'T BEEN MOVING WHEN IT HAD ISSUES AGAIN BUT THE ENGINE HAS DAMAGE AS IF IT'S BEEN HAVING ISSUES FOR A BIT AND WE NEED A NEW ENGINE. FROM WHAT I'VE GATHERED THERE SEEMS TO BE AN ONGOING ISSUE WITH THE TIMING CHAINS STRETCHING/BREAKING AND DESTROYING THE ENGINES ON THIS MODEL. I'M SURPRISED THAT I HAVEN'T SEEN A RECALL YET. OUR BILL WAS GOING TO BE 1500 AND NOW WE ARE ANTICIPATING 9000 FOR SOMETHING THAT SHOULD NEVER HAVE HAPPENED. WE ARE JUST FORTUNATE WE WEREN'T DRIVING WHEN IT DID. HAD WE BEEN NOTIFIED OF THIS ONGOING ISSUE AHEAD OF TIME WHEN WE FIRST EXPERIENCED THE LOSS OF OIL AND THE JUMPING WE COULD HAVE CAUGHT IT IN TIME TO FIX IT.
