NHTSA Complaint #11400008 — 2015 BUICK REGAL

I STARTED EXPERIENCING EXCESSIVE OIL BURN AT AROUND. SINCE THEN, I HAVE CHECKED MY OIL BIWEEKLY TO TOP OFF AND KEEP AT PROPER LEVELS ALONG WITH CONSISTENT OIL CHANGES AS THE OIL GETS DIRTY QUICKLY. DEALERSHIPS BEFORE HAVE TOLD ME THAT ITS "NORMAL" FOR THESE ENGINES. I DISCOVERED A BAD OIL LEAK. VACUUM PUMP ISSUES. MULTIPLE CAMSHAFT SEALS WORN AWAY, THAT WERE HARD AS ROCK FROM EXCESSIVE HEAT INCLUDING PISTON SEALS THAT HAD BEEN AFFECTED. THOUGHT THIS POSSIBLY HAD FIXED THE EXCESSIVE OIL BURN. A FEW WEEKS LATER I RECEIVED THE OIL LEVEL LOW NOTIFICATION ON THE CAR COMPUTER. I CHECK AND ITS VERY LOW. THE OIL BURN IS CONTINUING WITH NO CLEAR SIGNS OF AN OIL LEAK WITH DIRTY OIL. THERE IS POSSIBLY MORE PROBLEMS WITHIN THE ENGINE THAT AREN'T SEEN. I HAVE CHECKED PREVIOUS COMPLAINTS. I NOTICE THAT THIS ENGINE HAS MANY OF THE SAME PROBLEMS WITH THE TURBO PACKAGE ON GM VEHICLES. IT HAS A ROUGH IDLE AND ENGINE HESITATION. THESE CHARACTERISTICS SEEM TO INCLUDE INCONSISTENT ENGINE PERFORMANCE SOUND AND ARE FELT THROUGH THE PEDALS, THE DRIVER'S SEAT AND STEERING WHEEL, THERE IS A PUTTER AND HESITATES WHILE ACCELERATING.
