RPM lowers very slowly to Idle
4 Answers
No, this is not normal. While in "park" As soon as you let off of the accelerator, the RPM's should drop to idle within a few seconds.

The dealer where I bought it told me that since it is a four wheel drive vehicle, this is normal. Should I believe them? .....or should I get an opinion from the Chrysler Corporation? Thank you.
By the way, I bought it used, from a Mercedes dealer.
Being 4 wheel drive would have nothing to do with your RPM's hanging. If you are in park, the engine is disengaged from the transmission/drivetrain and should not hang at 2500 RPM. It could be a mechanical throttle issue or throttle sensor/servo hanging up.
