At 80,000 miles, after pulling out of parking, when I applied brakes the car started making rumbling noise from the engine and lurched forward despite pressing on brakes to stop. Pulled into a parking spot, while continuing to fight lurching of vehicle and turned car off to check engine oil, transmission oil, and power steering oil levels. All were fine. When attempted restart of vehicle, loud rumbling noise from engine, check engine light flickered and the car failed to start. Required a tow home from 100 miles away and $400. Hooked up obd, and received the following faults p0008, p0303, p0305, p0017, p0300, p0301. After researching on-line, common faults for timing chain issue estimate $3-4 thousand repair. Also, found 2007-2009 Acadia received extended warranty for same issue. However, 2010 not covered despite finding approximately 15 identical 2010 GMC Acadia on NHTSA site. I will be calling dealership first workday, however expect to be told timing chain issue based on codes and that GMC will not cover the repair since I am outside of the 5 year warranty, despite less than their 100,000 mile coverage.
