Cruze is getting a new turbo and a new water pump.
I took it back to the shop yesterday because, after having the cam cover/PCV replaced last week, the CEL came back on over the weekend. I hooked up my code reader and it was the “Turbo Underboost” code again, so I made an appointment for yesterday and took it back. I also mentioned it leaks coolant and I have to top it off every 4-6 weeks. I got a call yesterday evening that they had found both issues, the leak was due to a bad water pump seal and they went ahead and replaced it and the pump. They don’t have the parts for the turbo, though, so it could be another couple of days but they will fix that and both should be covered under warranty.
