October 2024 the turbocharger was replaced. A few weeks ago check engine light came on. Bad turbocharger again while I was on a highway the car stopped running. Dealer said they will not replace it under the parts warranty. They said it was 3 quarts low on oil and I need to show receipts for last 3 oil changes. From previous times there they knew my son is a mechanic & did oil changes. They wanted me to call my son to ask him how much oil he put in 🄠after looking online it is a very common problem with the Chevy turbochargers. It will but an excessive amount of oil and cause it to be black and sludgy. I emailed the general manager. He never responded. I also filed a complaint with GM and consumer protection. When they replaced it in October it was still under the extended warranty. It is now over the 100,000 miles. However, I think a turbocharger should last more than 6 months. I could have been killed on the highway while broken down due to a part they know is defective. Instead they treated me like trash. It is not the first time they have done this to me. The car already has a new radiator, transmission, faulty turbocharger, and something with the valves was fixed. The car is a lemon. I just want them to be held accountable since they know this is a common occurrence with the Chevy turbochargers
