2015 GMC Terrain Engine

BURNING EXCESSIVE AMOUNTS OF OIL.

SMELT SOMETHING BURNING WHILE DRIVING. CAR STARTED BUCKING AND JERKING. I PULLED INTO A PARKING LOT AND NOTICED A PUDDLE OF OIL LEAKING OUT UNDERNEATH MY CAR. NO CHECK ENGINE LIGHT OR ANY NOTIFICATION THAT ANYTHING WAS WRONG. HAD IT TOWED TO DEALERSHIP AND THEY TOLD ME PVC FROZE UP AND BLEW OUT REAR MAIN SEAL. THIS IS THE 2ND TIME THIS HAS HAPPENED TO US THIS YEAR. WE OWN ANOTHER GMC (2013 EQUINOX) AND THE EXACT SAME THING HAPPENED 2 WEEKS EARLIER WITH IT. FRUSTRATING THAT GMC IS AWARE OF THIS DEFECT WITH THEIR ENGINES AND NOT WILLING TO ISSUE A RECALL TO CORRECT IT. WE HAD TO PAY $2500 TO FIX THE EQUINOX. LUCKILY THE TERRAIN IS STILL UNDER FACTORY WARRANTY BUT WITH BOTH CARS WE WERE OUT OF A VEHICLE FOR SEVERAL DAYS. WILL IT HAPPEN AGAIN???
