Service Department is terrible. We have purchased multiple vehicles from this dealership and always been treated well on the sales side... however.., We brought our Cadillac in for a check engine light and after paying a diagnosis fee were informed that gas tank would have to be dropped to repair a manufacturers defect at my cost - $2800!!! Took vehicle to a different shop where they smoke charged the system, found the problem and replaced fuel pump and accessory lines for $700. Shop showed me the defective part and informed me that there was no way that they properly checked vehicle and that any shop that missed this should be considered very suspect... Very disappointed and my loyalty as a customer (4 cars) is over...
