NHTSA Complaint #11577798 — 2018 ALFA ROMEO STELVIO

I have had several incidents with my Alfa Romero Stelvio losing power while driving, This problem has been going on for quite some time, i have had several parts changed out with the same results a few weeks or months later. I took the vehicle to Jim Ellis Alfa Romero for repairs and told them the vehicle was losing power while driving and was told that this problem has occurred on several Stelvios. I left my car with Jim Ellis and a few days later I was told all was good. I didn’t even get a mile away before I loss power again. I brought it back to Jim Ellis and left it again and a few hours later they called and said that the Stelvio needed a new turbocharger that would be $4000 plus installation fees. How is this possible if you told me you had taken care of the issue, and the car didn't even make it a mile.
