We can add my 2017 GTI Autobahn to the list of casualties. In summary:
- 3/27: purchased vehicle new with 22 miles late on Monday. On drive home the stereo input controls stopped working and the head unit reset itself
- 3/28: navigation wouldn't start and was stuck searching for data
- 3/29: navigation somehow worked again; drove two hours without issue
- 3/30: navigation wouldn't work at all (searching and searching) and the system completely reset itself 5 times in 25 minutes, which seemed to stop when I yanked the SD navigation card
- 3/31 and 4/1: system wouldn't connect to iPhone via bluetooth, but I thought, at least until I can get to the dealer, I can use Apple CarPlay via USB. Nope. The reset cycle continued and only SiriusXM stations worked. Had to turn bluetooth off on phone and disconnect from USB to stop system resets
- 4/2: system resets itself even on just SiriusXM, when it does, the input and adjustment buttons (volume, etc.) don't work until a hard reset is performed
So, less than 500 miles in and I've had to return to use my phone headphones again - same as I did in the 1999 Honda Accord with 204k miles I traded in. Guess I'll be getting to know my local service department now. Had been hoping that a new vehicle would keep me from wasting my time in that way. At least it drives quite well.
