When slowing down at a stop sign, in snowy conditions, the vehicle went into brake assist and locked the brakes up. Causing the vehicle to slide at an interesting and collide with another car. I had complained several times to the dealer about the braking system being to sensitive and touchy before the accident. This was purchased new and the accident happened about 1800 miles on it. Also, the air bag did not deploy. I was told by the dealer, it was because the impact was not hard enough. But the alerts on my phone, said air bag failure Since the accident, I have had this jeep back to the dealer several times. I asked for a full brake inspection, because I have never driven a vehicle that 1- brakes for you for no reason, 2- extremely touchy. The dealer service dept admitted the brakes were touchy, and drove an identical model to compare, and concluded that it must be normal. Didnt actually inspect them. It is NOT normal, and I do not feel safe driving this vehicle in the winter. I have since turned off all brake assist options in the settings, but it is still auto braking. Today at about 3000 miles, when slowing down to make a turn, the emergency braking system started acting up with no one close to me. There is something very wrong with this system, and needs to be addressed before serious injuries happen.
