I have had a lot of problems with my turbo on my 14 Buick Encore

What is your question?

The first problem on my beautiful 2014 Buick Encore was a coolant leak on the turbo that had something to do with the AC. Was still under warranty so brought it to dealership took them forever but they fixed. On July 27,2020 while on a short trip my check engine light came on while the AC was running. I went to autozone and had error code checked and it said the turbo is misfiring or under producing. I’m extremely hesitant bringing back to dealership please advise.

What makes this problem better or worse?

Not running the AC

How long has your 2014 Buick Encore had this problem?

2 days or so
