Why is my 2007 GMC Sierra making a noise like someone tapping on an empty vegetable can...sounds like it's coming from underneath the motor
I have a 2007 GMC Sierra 1500, I bought it brand new. I was driving home from work and a tapping sound started, it sounded like something was wrapped around my drive shaft. The service stabilatrack warning light came on, I drove about 10 miles and I heard a loud bang, and the truck powered down. I got it toad to my mechanic and he told me my engine seized up. It has 73,000 miles and I have all maintenance done at the dealer according to their schedule. My guy said the 5.3 engine in the 007-09 are not strong at all.
The problem was a lifter that was eat up by something or just faulty....changed it and now runs great
