The first time I brought my new Buick Encore in for service, I was reporting a specific problem that got the usual "could not duplicate" response even though while I was there and explained the problem, nobody was all that interested in me duplicating it for them before they said they could not duplicate the problem. This resulted in alot of follow up calls from them which showed they are interested and I honestly learned to live with the issue and it is just an annoyance, but not a game changer issue. (the ignition switch has to be pushed dead center or it doesn't really work as it should and goes into a type of accessory mode).
Anyway, months later I came back for service on both of my Buicks (back to back service visits) with good results. They called to remind me of my pending service visits, which is good to make sure I hadn't forgotten, and they got them done in a very quick period of time. One reported issue was dealt with and the resolution, which sounding like maybe wasn't quite right, seems to be solved and hopefully will continue to stay resolved.
One of the service writers is a bit of an antagonist, and that is annoying - I say "My other one doesn't do that" and he explains that it isn't the same car; I'm thinking but don't say it "Really, I didn't know that", but Mom always said two wrongs don't make a right. But he redeemed himself by hand writing a nice note on the receipt, and that was appreciated. It seems as the manager sits near them, heard this, and never interjected to tell the guy that this response isn't appropriate. Hopefully he addressed it after I left.
I'll probably continue to go back for service, as I prefer dealer service to ensure things get done properly and are documented in their record keeping system vs. holding onto receipts or whatever.
Car dealers in general could learn alot by being a customer in the service department without them knowing who they are, like a secret shopper program. My honesty in this review should be a word to the wise that as a paying customer, who has purchased new cars and returned for service at their dealership, that I will not continue to support a dealership in which I get greeted with antagonists or get told "Could not duplicate" when I offered to duplicate for them prior to leaving the car with them for the reported problem. I will just go elsewhere and you'll find out only after I've gone to another dealership and you've lost me as a customer - that was why I never went back to the last GMC dealership when I was ready to trade in and trade up - their service people were so unable to be nice upon dropping off, I felt like I should have jumped in and rubbed their shoulders or do the write up for them because they were too slow on the computer and I was imposing upon them by wanting to drop my car off and pay for the services they were going to perform.
All in all, they get the job done and overall I'm satisfied the very basic services were done properly. I have not had any serious service concerns performed at this dealership yet.
