When driving my car out of nowhere with no warning as I proceed to drive off from a red light or stop sign my car will ding and instantly and cut off at that point a light. Comes on saying shift to park and hit the start the car button when I hit the start button it cranks up but it's dangrous at that point I'm almost hit and and getting cursing out by the driver . My radio is going in and out losing bluetooth it will automatically disconnect and my seat belt has been repaired out of pocket.
