So I've had my car for two weeks and only have like 300 miles on it and my boost gauge is broken already. It doesn't light up and the needle is stuck between 20 and -30. I believe it worked fine until I took my car to the dealer to have some weird wax stuff they sold me put on and now it's broke. I looked under the hood and don't see anything unplugged. Do you think it's a really easy fix and I'm just missing something or should I take it back to the dealer?

That stupid compartment thing that the trunk release button is inside broke already too. Love the car but what the hell?

Pic is with the car off but it doesn't move or light up at all anymore.

 

thats what the warrenty is for

 

I'm just hoping I don't have two things break every 300 miles.
