Being on a road trip for the last 10 days, this morning , my return home day, I started the car after having it parked for a couple of days and it happened, parking assist, sensors and infotainment sound were all out of order, hadn't happened in some time and elected to happen today on my 4 hour trip back home. Well, I tried rebooting the infotainment, nothing happened, I shut off the car for a few minutes, as this did the trick previously, nothing happened, so I couldn't wait the whole day and I was on my way back, no radio, no sound at all so me and the engine and road noise (thankfully the engine noise is almost non existent), stopped to gas up, started up again still no sound and no parking assistance. Anyhow, I got home after 4 hours listening and talking to my self, parked got all my stuff to my house , spent a few more minutes inhouse before going out to grab a bite to eat, started up the car and ALL was back to normal, sound, parking assist etc. All it needed was a few extra minutes to reset, now I remember when the same happened in the past it all went back to normal after a restart but I also remember the car been stopped, out of coincidence, for more than 10-15 minutes. Seems it needs some time before restarting to have the systems working again.
