Details
What's wrong: The calibration of the transfer case control module could cause insufficient high speed gear engagement.
Why it matters: If the gear is not engaged, the vehicle can roll when the transmission is in "park" and a crash could result without warning.
The fix: Dealers will update the transfer case control module calibration to increase gear engagement. Owner notification began November 6, 2001.
