When I started car I got service messages for side detection system, tire monitor system, safety restraint system, front camera system, trailer break system and theft deterrent system. Each one gave option to dismiss. When I would dismiss the messages would come back. When I was driving, all the things on dash, mph, oil, battery etc all stayed on zero. Super dangerous and I could have died!!!!!!. No blinker sound.
