Have had several issues with the radio losing my presets and custom settings. It would reboot several times. Also had collision sensors kept turning off with a service soon message. At dealer today they did the upgrade on radio along ( service bulletin 17-na- 071 radio issues along with 17-na097 side blind zone) with resetting all the sensors and making sure grounds were good. Only had 1400 miles and already in shop 2 times for service checks. 1 st time I had 30 codes stored in several sensors they said but had no ideas on what caused them. Hopefully last time in.
