Suspension Related Problems of the 2015 Dodge Grand Caravan

Suspension problem

I drove like regular the transmission was starting to delay in response but nothing to this extreme. I parked it after an evening of m working; once parked the vehicle will shift through all gears but only park is engaged and stays engaged even while shifting to r, n, d it only stays parked. This is a safety issue as I can not even get it in neutral to tow and get it looked at or anything. I was not expecting it to not engage ever again so my vehicle is on an angle parked and I cannot gear shit it to n to get it moved and out of the road. Also the sway bar seems to be faulty as well. I think that’s suspension but it rocks back and forth really badly actually while taking on bumps or cracks it’s caused concerns enough that I stopped having my 3 children in it now while driving until an investigation is completed.
