| Feb 2025 | ENGINE | The first time it happened my Truck started shaking a lot on the highway and it left me stranded on the side of the road. It had around 20,000 miles on it. When it got repaired I was told it had to do with the lifters on the left side of the engine. Took them 2 weeks to fix the issue. The second time it happened was on the ramp getting on to the highway, this time at 58,000 miles and now the right side lifters. Except this time they couldn’t fix it and they are going to replace the whole engine and give me a new one. Only thing is that it's been in Chevrolet shop for over 2 months and they have an ETA of a new Engine arriving in about a month if even that. So currently don't have my truck. | Crash: No Fire: No | Unknown |
