Had this problem for 6 months now and no one else seems to have the same issue.
SRT drive modes. I have set a custom drive mode which consists of:
transmission - track
paddle shifters - on
all wheel drive - sport
stability control - sport
suspension - sport
steering - track
Operation on the daily is normal, jump in, start up the car, double tap srt button, start driving in my custom set drive mode.
Now what pisses me off is, every 3 days or so I will start the car and double tap the srt button, only to see my "custom setting" has reverted back to default "street" on everything. Nothing else gets reset on the uconnect, only the srt drive modes..
