Bring it to the dealer for diagnosis , then bring it to a well equipped independent shop for a second diag.and see if they come up with the same.If your looking at thousands to repair , then the price of two diagnosis to be more certain would be well worth it. Whomever you have do the repairs , hold them accountable , for their diagnosis.
