Worst experience ever! The shop was unable to diagnose my problem and once they finally did they refused to honor my warranty . After deciding to go elsewhere I drove off to find ALL of my lights on dash, check engine , ABS , brakes , etc on AND my speedometer doesn t work! After contacting them they tried to say it came in like that. Showed me an invoice with the incorrect name and service dates ! I will be taking legal action and will NEVER return!
