Bear with me for a second if this seems like a bad place to post this, or if this is in poor form, but I feel like I just got screwed on a repair and I need to figure out what the right play is, or if there even is a right play.
Back in October 2013 I bought a used 2012 Mustang V6 premium with just over 15,000 miles on it. It was sold to me with a remaining factory warranty from a Ford dealership. I also bought extended warranty coverage at that time.
I just got done shelling out 900 bucks to get the rear parking sensors fixed. According to the mechanic at the dealership that did the work, an aftermarket module of some kind had been installed and was interfering with the operation of the sensors.
He speculated with me that the previous owner, at some point, had installed an aftermarket security system, or remote starter or something, and that this was a remnant from that system after being removed. As a result, he said, there was no warranty coverage available to me, as the parking sensors allegedly failed as a result of this aftermarket module the he found in there.
So, here's the question:
Do I get mad at the dealership that sold me the car? Were they legally able to sell it with a warranty if there were defective/modified components? Are they liable if they didn't know?
Do I get mad at the dealership that did the work. Is there something fishy about this diagnosis?
... or is this really just an unfortunate set of circumstances and I just need to suck it up?
It always sucks to shell out this kind of cash, but I want to hear from some other owners before I start calling around tomorrow . What are your thoughts, guys?
