My car become worse after I did some service in a big car dealer?

Question

Hi there, I just spent 2700$ to check every thing of my car and fixed someting in McKenna Volkswagen on Norwalk one week ago. But my car become worse than befor, my check engine light is on sometimes and it will speed up little bit by it self when I start the car. (I didnt step on the gas )

Is this their fault? Because they told me my car is ok` every thing is fine now, but my car become worse... I think is their responsibility. What should I do if they still wanna to charge me for that ? I dont want spend money just because their mistake.

Answer 1

2700 dollars later  and  it runs lousey and they tell you the car is fine and the check engine lite is on. Get your money  back or take them to court or call the volkswagen head office and complain about them BUT don't let them s***w you like they are trying now.

Answer 2

take it back to the dealer and complain they have to tell you everything that's wrong and maybe they have a bad part that they put on they should fix it no charge make sure you talk to the mane service manager not a flunky they should make it good
