I had one some time ago with a dealer where I bought a used car and would call it failed excuse of the year (tnx to my car knowledge I have as a DIY-guy ☺).

A month after buying (every used car has to have at least one month warranty when sold) I brought it to the dealer to check it because AC was not blowing cold enough and car wasn't heading straight on a straight road.

Dealer tried to convince me that maybe the battery is shot for AC problems (yeah sure, and my car starts up without problems, I just wonder how😅)

When they checked underbody they said sth was loosed but that was not a huge problem (and my car suddenly went straight by a miracle after they repaired that)

They tried to scam me. Just imagine how they manage to fool pure laics 😕.
