Brought my car in for a diagnostic test which they failed to do and fail to fix the issue they want me to bring my car in multiple times for them to figure out why the check engine light is on and stead of doing a complete inspection to figure out why the light is on. I will never bring my car back to this dealership spoke to Kevin the general manager over the dealership and he stated to me while your car is under warranty so every time you bring it in to get fixed we re going to get paid Regardless.
