So I noticed last night that the brakes were kind of studdering like they when trying to stop in snow. However, there is no snow. No rain. Nothing. I put on focal K5 18"s a few weeks back and everything was smooth as butter. But this morning while on my way to the local MAC Donalds restauraunt I got three instantanious beeps....ABS Service, TC turned off, Assissted steering off. Why? Is it because a speed sensor in a wheel? Loose wire...this sucks.
