I can't speak for the sales department, but if you intend to have your car serviced here, do so at your own risk. Service department is incompetent, unsympathetic and will take ZERO responsibility for their actions. And now of course my car is leper that no dealership or GM wants to touch!
In Nov 2017 I took my 2017 Volt in for a simple recall service. My car's performance was flawless and I loved it, racking up about 13k miles in a year and a half. Upon getting the car back, the Lane Departure features were inop (a costly upgraded feature that I specifically waited until 2017 model year to purchase for this vehicle and a "safety" feature that is tied into the cars fully drive-by-wire braking, automatic braking, and steering functions).
Upon returning the car to them a few weeks later for the remedy service, I'm told by the service advisor that in performing the repairs GM allegedly never instructed them to reprogram that feature (since speaking with another GM dealership service department that is well versed in the latest Chevy functions, that feature had nothing to do with the recall repair.) I think little of it and thank them for at least addressing it in this follow up visit. They assure me that it works fine now (despite learning later that they have NO other vehicles on the lot to confirm how the operation is to properly work anyhow).
Long story shortened due to a legal breach of contract lawsuit pending, over the course of 1 week they acknowledge, confirm and document the problem, GM/Chevrolet Customer DisService 'reps' claim a high escalation of the matter and lied to me as to the 'status' of the repair and their alleged interaction with the dealership, the dealer states that can't undo what they did and will do nothing more and demand that I bring back the loaner car to the point of harassing me and then threaten to call the police. 1 WEEK! I invite them to come get their loaner and inform them that I will not take possession of the car until they repair their error. So what do these unscrupulous guys do? They drive my car, leave it in the street in front of my neighbor's house, facing the wrong side of the road, doors unlocked, keys in obviously visible in the cupholders and jump into their loaner. They were so anxious to sneak & drop my car that they brought their own spare key and I had to flag them down before pulling out of my driveway to give them back the key that I was given.
Horrendous integrity and they can rest assure I will be joining my neighbors in NEVER taking my car to them for further disservice again.
