2018 Chrysler Pacifica body & structure problems

While driving our 2018 chrysler pacifica on I-95 south in nh, traffic came to an abrupt stop and we rear-ended a jeep wrangler at approximately 30-40 MPH. I braked for about 20 ft and struck the jeep. Our airbags deployed and the engine compartment immediately burst into flames upon impact. The flames were so immediate and so violent that my wife and I only had time to remove our young daughters from the middle row of the vehicle. The accident itself was minor, the jeep was able to drive away after the accident.

Came to full stop at a light on a 2 lane highway. There was no one in front of me and one care behind. Almost immediately after stopping for the light, the engine stopped, the transmission indicator light flashed the light under "d" and the gauge cluster flashed multiple lights. I can only remember seeing fwc or fcw flashing but there were other lights. Auto start/stop was not disabled so I was initially not surprised by the engine stopping at a light.
