Best gmc dealer in Saginaw, Michigan (MI) 2024

I brought my vehicle in to the service department because I've had issues with traction on dry roads, I needed an alignment and a tire rotation. I had an appt at 7:45, the service department called at 8 to make sure they knew what was wrong. At 1 I had to call to check on the status, I was told that they couldn't find anything wrong, the rotation and inspection were completed and all that was left was an alignment. I show up at 4 to pick it up only to be told that they weren't done with it. I finally got my vehicle back at 440, paid 211 dollars. Upon arriving home after driving through several towns (still experiencing the issue I brought it in for) I noticed that there was a lug nut missing!!!!! I was able to get in contact with the service manager, I will be getting a refund and he really is trying to make this right. But I will be very hesitant to return as this was a very big safety issue. Also, when I was looking at the missing lug nut and looking at the tires, every single one of them has a bald spot going down the middle. One would certainly think that this would be the cause of my stability issue?? Also, if the tires were rotated the tech never even so much as glanced at the tires? If things were inspected correctly how was this also missed? No matter how they fix these issues I would be very nervous to go back. ~Laurie
