Service was done to correct the issue. The $32 part cost $780 to replace. Service agent did his job fine. The 2020 Chevy Blazer had 31.8k miles and 5 year 60k drive train expired 30 days before. This was a known Chevy issue. Randy Marion on top put a 3% CC fee.
So, unless it is within warranty time or miles, go to a certified mechanic. Will most likely cost you less less.
