My service appointment experience this past weekend was not good. After the service when I am driving my car back found that check engine light is on. When I took my car back, my service advisor found that some cables are not connected under the hood. He showed it to service manager and provided a credit of $50, that's nice of him. I hope McDavid put in additional checks to double check the Service work these mistakes can turn out to be dangerous to customers.
