I took my car in for a 7:45 AM appointment to have a 170000 mile check up, which can take about 3 hours or so to do so they offered me a ride back home as they had no loaners. While at home, I didn't receive a phone call until about 2:30 PM and they told me what was wrong and the repair costs I had to ok. I was surprised at the lateness, but as long as I got my car back by the end of the day I had no real issue with it. 5:45 PM came and I still had not heard that my car was finished. I called the operator and she told me that the VW Service had closed at 5. I had her check to see if my car was awaiting pick up and it wasn't. At no point, did they ever say my car was staying overnight. I needed my car as it was my only car, especially when I was using it to go out of town the next day. I was not happy. All I could do was wait until they opened the next day. I finally spoke with Jeremy, who apologized as he was originally told by the parts person that the part needed was in stock before he left work that day. However, apparently it wasn't and they wouldn't have the part until 8:15 AM and no one called to tell me that. When I finally got my car at 11:15 AM that next day, the bill had no discount on it for the coupon that I was using for the 170000, so I had to wait for that. However, I should have received a small discount regardless of a having a coupon. I would have been satisfied with a free oil change for the problem this caused. There were many apologies for the mix-up, but my extreme frustration is that I told them I needed my car to travel out of town when I dropped it off. I even mentioned it again when they called with the repair costs. I didn't have my only vehicle in the evening when I needed to run a bunch of errands before I left. None of which I was able to do. I was told I would have gotten a loaner should my car not be fixed to take out of town, but the point was there was no communication and there supposedly wasn't a loaner. It was a major inconvenience for me and all I got was apologies. They had no idea that I had to be at my out of town destination at a certain time because I didn't think I needed to give that level of detail. If this wasn't so close to a previous problem I had with this service department, I would have not have written a review as I respected and appreciated how they handled that problem as it was their fault. However, if this is the trend in service, I may have to rethink taking my car there.
