“Hello, I have a 2018 Bmw M3 that is about 12 months old. There was a sirius xm (satellite radio) trial period of 1 year, and now that it is about to expire, there is an advertisement in my navigation window that comes up every time I turn on the car, that has to be cleared via pressing ok or else it doesn't go away. The safety concern is that if I turn on the car and go into reverse, the reverse camera will show but gets interrupted by the sirius xm advertisement, and doesn't come back until the advertisement to renew is manually cleared out. …”

I filled up my tank and gas started leaking from the bottom. 2015-2016 BMW covers it but mine is made in 2017 has the same issue but no recall. This is very dangerous because it’s gas related.”
