The car was clicking when it was first started up, a short time later it started to shake terribly which forced my [XXX] son who was driving the vehicle at the time to pull over, on a major toll-way in heavy traffic. Engine light started to blink and traction control light came on. I immediately took the car into the dealer and was told I need new lifters ($3800 + Tax) and most likely a new engine (they quoted me $15,865). From what I am reading this issue is common place with the 6.2L engine...frightening and very lucky my son was not injured. I have filed a case with GMC - Case #[XXX] INFORMATION REDACTED PURSUANT TO THE FREEDOM OF INFORMATION ACT (FOIA), 5 U.S.C. 552(B)(6)
