NHTSA Complaint #11141225 — 2017 CHEVROLET TRAVERSE

MY ENGINE, WHILE THE CAR WAS STATIONARY, MADE A LOUD CRANKING NOISE. IT SOUNDED LIKE LARGE METAL PIECES GRINDING TOGETHER. THE ENTIRE CAR WOULD THEN RUMBLE AND THE ENGINE LIGHT WOULD COME ON. AFTER SITTING FOR A WHILE IT WOULD STOP. THE RUMBLING WOULD HAPPEN ALMOST EVERY TIME MY VEHICLE IS AT A STANDSTILL. IT WOULD ALSO DO A JERKING MOTION WHILE DRIVING ON THE ROAD. THE GM REPAIR MECHANICS SAID IT WAS A SMALL VALVE. THEY REPLACED IT BUT THE SAME THING CONTINUED TO HAPPEN. MY CAR WAS BRAND NEW WHEN I PURCHASED IT IN 2017.
