I took it in for the long overdue headlight recall issue. Every recall experience I've ever had has basically resulted in ruining a good car, so I waited until the headlights actually failed before letting the dealer do this work.
Why, oh! Why then didn't you follow your gut instinct and avoid them at any cost.
I am sorry they messed your car up (to put it mildly).
Please do not let them convince you that it is not worth the time and money to fix, while they scheme to sell you another car.
A little wiring damage is no reason to get rid of an otherwise good vehicle.
Beleive me on that point. See this.
Take it to another shop if you cannot repair it yourself.
An electrician could most likely do the repair for you.
I would not trust that dealer to replace a light bulb.
It sounds like the mechanic s being trained on YOUR dime.
Not what I would call "service"
Just my 2c & heartfelt empathy sent your way.
