My plan now is to take my car to a regular mechanic, and let them fix it. My Mirage is new enough it's worth sinking some money into it.
On principle I feel that I bought my 10 year warranty the day I bought my car.
That said, I can't even afford the time any more to spend ,yet another day, at the dealer. Last time I felt like I was at the greyhound station, waiting for transportation. It's annoying, but clearly they're not gonna really 'fix' my issue.
The passive-aggressive service tech is about 1 string from me snapping, and I'm not getting entangled. It's just a car, lots of people have far larger issues so I don't want to be a jerk.
