Traveling on the interstate late at night in the winter with my family, which includes small children, a clicking noise began but then went away. No diagnostic lamps came on, everything seemed fine, vehicle responded appropriately. Moments later, on a remote stretch of interstate, we lost power and the engine shut down.
I was driving down the interstate and with the no warning the vehicle would not accelerate any longer and tried to coast onto the exit. Totally stopped blocking all traffic on the exit. Could not crank the engine or at least put in to neutral to push out of the road.
On while driving on the highway near Wash DC engine stopped, went to neutral. Would not start again. OnStar towed vehicle to Koons Chevrolet GMC Tyson in Vienna VA. On Tuesday Koons Service Dept. looked at vehicle and determined that it was a thrown bearing and needed a new engine. There are 28,712 miles on vehicle.
Main bearing failure on my 6.2L at 17,000 miles. Starting making knocking noise, and within two miles it died and wouldn’t restart. No check engine light or warning lights. Blew a 40 amp fuse. Once replaced started but knocked and died. Dealership determined spun main causing internal engine failure. Motor replaced.
