Yesterday morning when I started the car and buckled up the "fasten seat belt" warning continued on and the chime kept going off for about 5 minutes. Then no more chime or msg on cluster, but the seat belt sign on dash continued on. The steering wheel controls are not working while all this is happening. The car continued doing this today as well every time I start it. Then, on top of that, this evening, the headlights started flickering all the way from home to the movie theater and on the way home, and the interior lights came on and stayed on all the way home.
Anyone has any idea
what could be causing all this? Any input would be greatly appreciated.
