The recall affects 576,417 2001-2002 Dodge Dakota trucks, Dodge Durango sport utility vehicles and Dodge Ram vans and the 2002 Dodge Ram pickup. In some cases, long-term wear on the gearshift assembly could erode the height of the shift blocker, creating the potential for the vehicle to shift out of park.
Chrysler spokesman Max Gates said there have been nine incidents involving injuries connected to the issue. No fatalities have been reported, he said in an e-mail.
Owners will be notified beginning in January 2008 and dealers will replace the gearshift blocker and bracket assembly.
In the interim, vehicle owners are advised to use the parking brake at all times when the vehicle is not in use, Gates said.
