My truck is a 2017, but only has 46,000 miles on it. The engine light came on and it started banding loudly. I lost power and it would not go over 30 miles per hour. The dealer informed me the lifter failed and destroyed the cam shaft. Upon research, I have discovered this is a problem for many of the 5.3 engines. Many people are stuck now. I realize I have no warrantee, but I take excellent care of the truck and it only has 46,000 miles on it. It should not need a new motor, especially if it is due to a defect from GM. They knew about this issue and are doing nothing. I am now faced with an $11,000 quote for a new engine. This is wrong on so many levels.
