I'm very disappointed at the service department.
I had main software issue so I made appointment to fix my 2014 x5. My service adviser is Matthew Mueller. I dropped off and explain I need software reprogramming my car. He understand what is problem. 3 hours later came back to me and he said that, it is not ready yet. He said it will take about 1 day for reprogramming my car. He should told me early when I dropped off my car at dealer. Anyway I asked loan a car than, he said it is not available this time. so there is no choice just came back to home by my car. I loose 3 hours at the shop for nothing. Second time I dropped off my x5 for oil change and software reprogramming again. the oil change is great but they still didn't know what is problem going on about my car. I explained my previous visit and recommendation software reprogramming. after a few second later adviser came to me and he said that they can't not fix the day(I already know), come back next time. well I don't want to wasted my own time again so I need to fix right now I complained. then he talk to manager after that he gave to me loan a car and completed repaired my x5. I still have problem. when they repair my car, they lost my USB memory stick which is in the center console box. they should know who took out memory stick and reprogramming my car. but they said may some there in my car but they don't knows. that is dear answer.
