Detroit, MI: Chrysler Group LLC (Chrysler) is recalling
644,354 model year 2011-2014 Jeep Grand Cherokee and Dodge Durango vehicles manufactured from January 5, 2010, through September 8, 2013. The affected vehicles have a brake booster with a center shell that may corrode and allow water to get inside.
The water inside could freeze and limit the braking ability of the vehicle, increasing the risk of a crash.
According to information on the National Highway Traffic Safety Administration website, Chrysler will notify owners, and dealers will add a water diverter shield to the booster after the booster has been tested to confirm it can hold an acceptable amount of vacuum pressure. If the booster inspection confirms an unacceptable loss of vacuum pressure, the booster will be replaced.
