It means you got chumped. Sorry to have to say it.

You bought a worn out POS that's going to cost you more in monthly maintenance than it will in payments.

It means there is an issue with the powertrain, because if it was just a stupid gas cap, the problem would be gone.

It means it's a booger on your finger and you need to wipe it off ASAP.

Unless it's covered under warranty, do NOT take a used car to a dealer for repair or maintenance

You will get HOSED. Like getting charged $50 for soiling an oil rag. No joke.

Get rid of that thing.

I did the run around with my local Ford dealer with my '06 F-250 Powerstroke. I finally cornered the service manager after the 2nd catastrophic breakdown in 2 weeks and after 30 minutes of bugging him he finally nervously whispered to me that I had 4 months of warranty left to get rid of the thing.
Find an independent mechanic you trust at least on a business level and do your changes and tune-ups through him. You will save thousands.

Another thing about small town dealerships: They have you over a barrel and they know it. Olympia's like that. All Star knows damn well that locals have to drive 40 miles before you find another dealership and they treat you accordingly. I don't even shop for cars locally anymore, but drive to Tacoma, Seattle, or Bellevue.

Good luck.
