For the last year my car has ran badly. Very rough idle, engine light throwing multiple codes, bad gas mileage, heavy oil consumption, and pulsating throttle while parked and driving. I've taken it to the dealership and for an entire year they've given me the runaround. On Monday I took it back in to rancho motor company in victorville, California and they finally say it's the timing chain. The recall warranty voided at 120000 miles. Now they refuse to honor the recall. My car is dangerous to drive.
Engine began burning oil. Gm replaced damage to timing chain but did not fix the problem in the engine that causes it to burn oil. So now, I have to add . 5 quart every 300 miles. My technician tells me he has many in the same boat.
