Car Will Not Accelerate problems of the 2016 Volvo XC90

While driving at @35mph on a busy city street the car decelerated suddenly without warning and the drivers instrument panel went out, giving me, the driver a blank screen. Car would not accelerate and slowed to about 5mph. No previous indication of this happening. Spoke with 2 Volvo service departments and both providers stated this has happened to other cars before. This is a huge safety defect especially on a brand new car. What if I had been on a freeway going 70mph and the car decelerates all of a sudden? very concerned that my children and I will die in a crash getting rear ended on the freeway if this should happen again.

The dashboard instrument panel suddenly went blank on a city street and the car could not accelerate more than about 5-10 miles per hour. It's frightening to imaging what would have happened if this occurred on a highway. Volvo's towing company put rear wheels on ground and damage all wheel drive system during towing. After stayed at dealership for a month but within 48 hours after pickup, a warning message "all wheel drive service required" popped up.
