My issues started almost two years ago when dropping my child off at daycare. I was on the highway and noticed a loud ticking noise coming from the engine. At first I was not sure what it was until I pulled in the daycare and it was evident something was wrong. At that point the stablitrak and traction control light started flashing. I had to have the vehicle towed because I tried to move it and when I put it in gear it jerked so hard I was scared the engine blew. I took it to the certified chevy mechanic, cylinder 6 misfire. We replaced the plugs, coil packs etc, trying to see what the issue could be. He finally replaced all 16 lifters, cam, head gaskets and oil pump as well. Once he got it together, it was still a misfire on cylinder 6. He took it apart to look at the pistons, they were fine. The top of the motor he practically everything brand new on it. The chevy dealership are aware of the lifter issues with this vehicle and blatantly told me, I need a new engine or could purchase a new vehicle. Still no resolve as of June 23, 2020! please issue a recall on this as so many of these vehicles have this issue and it's not fair to us that they designed the engine so poorly.
