Jeff,

I did a search on the forum regarding this but did not come up with much (perhaps I overlooked it). Anyway a search on the NHTSA.DOT.GOV website lists the following recall for the transmission parking prawl for certain '05 & '06 X5's-

"
NHTSA Campaign ID Number: 05V504000
Summary:
CERTAIN PASSENGER VEHICLES MAY HAVE BEEN BUILT WITH AN INCORRECTLY MANUFACTURED AUTOMATIC TRANSMISSION PARKING PAWL GUIDE PLATE.
Consequence:
THIS COULD CAUSE THE PARKING LOCK SYSTEM NOT TO ENGAGE, AFTER THE TRANSMISSION IS PLACED IN THE PARK ("P") POSITION. IF THE VEHICLE WAS PARKED ON AN INCLINE, AND THE PARKING BRAKE WAS NOT ENGAGED, THIS COULD RESULT IN A VEHICLE ROLLAWAY CONDITION.
Remedy:
DEALERS WILL REPAIR AND REPLACE THE AUTOMATIC TRANSMISSION GUIDE PLATE FREE OF CHARGE. THE RECALL BEGAN ON NOVEMBER 30, 2005. OWNERS MAY CONTACT BMW AT 1-800-332-4269.
Notes:
CUSTOMERS MAY ALSO CONTACT THE NATIONAL HIGHWAY TRAFFIC SAFETY ADMINISTRATION'S VEHICLE SAFETY HOTLINE AT 1-888-327-4236 (TTY 1-800-424-9153), OR GO TO HTTP://WWW.SAFERCAR.GOV.
"

My questions are-

1) Is this commonly known among members of the site?

2) Is it a big deal?

3) Not being a transmission expert, having the dealer repair it under warranty (if in fact it has not been done already, I purchased mine used and have not checked yet), would they open it up and then, replace the tranny fluid?

What are your thoughts at your convenience (would you get it fixed)?

Thanks-
