1999 Chrysler Concorde transmission problems

The consumer stated that her husband put their vehicle in park and got out of the vehicle. When he got out of the vehicle and closed the door, his vehicle began to roll forward. She stated he tried to catch it, but could not. He stated that the vehicle rolled down an embankment and damaged the front and side of their vehicle. No one else was involved. She states that they received a recall notice about 2 wks ago, but forgot exactly what it was for.

Transmission input sensor failed on my 1999 chrysler concorde lxi with 25,000+ miles causing the transmission to abruptly down shift causing vehicle to over rev engine which caused an abrupt slowdown which could have caused a rear end collision or a loss of control. Part id # is 4800878. Since my failure I have heard of 2 other failures just from people I've talked to. This is a problem chrysler is aware of. They should be held accountable for any accident which this failure contributes to.
