I just had my AC compressor? replaced on my 2018 Sport Touring at only 7500 miles. Luckily covered by warranty, but it would have cost around 17 to $1,800 if I had to pay for it myself. My local Pensacola dealer had the part in one day, & it took about 3 hours, with one hour letting it cool down to be able to work on it so the mechanic didn't burn his hands or arms on the hot engine area he had to get into. Sounds like someone is really trying to rip you off! Get other estimates, especially if not under warranty, & you are paying.
