My wife was driving down the highway and out of no where there was a loud taping sound, the vehicle started running real bad (skipping), the vehicle lost power and she lost control of the steering. As a result, she ran off the road into a ditch. this is a known concern with the 6.2 liter engines and all signs are pointing to lifter failure. She could have ben seriously injured and GM is responsible for this.
