Lose Power Steering problems of the 2018 Chrysler Pacifica

Several times, while driving 20-30mph as well as when stopped at a red light or a stop sign, the car has lost power steering (steering wheel locks, brake seems to lock in place), unable to accelerate or decelerate, dashboard flashes some message along the lines of "stop/start required" or "shift to p then desired gear", but even when attempting to shut off the car and restart, sometimes this does not even work. At times it has taken 2-3 minutes to even get the car to shut off completely in order to try to turn it back on (as if the car is completely frozen). This has happened on side streets, as well as at a stop sign and a red light on a busy road, which left me blocking traffic for several minutes, unable to operate my vehicle. This has happened at least 5-6 times in the last year, most recently twice in the last week.

On Sunday January 13th while getting off highway lost power steering while taking exit. Due to lack of power steering van went off the road up an embankment and damaged vehicle. I called Chrysler on 1/14/2019 and reported issue. Claim #57836097. I was told that someone from incident reporting team would be contacting me within 4-5 days. I have since called them again on 1/22/2019 and again today 1/28/2019. I have no choice but to drive vehicle because I am a 100% disabled veteran and in a powerchair. The van is customized for my powerchair and my only means of transportation. The power steering keeps going out intermittently and now other electrical issues are occuring now as well. The passenger side window comes down on its own, traction control light on dash goes on and off, stability warning flashes on dash and of course power steering light comes on and says service. Prior to the incident on the highway off ramp the steering went out for a few seconds. I brought it to bonneville dealer in manchester nh and they told me it was just a fluke. Obviously it was not a fluke and my van is now damaged. Drivers side sliding door does not close right and is bent upwards and not sure what else may be damaged. Waiting on Chrysler for next step.
