On the recalled trucks, which were built between March 2009 and October 2010 and are powered by the available Cummins diesel engine, excessive vent pressure in the reservoir cap could lead to a brake pedal that’s slow to return. As a result, the brake lights may remain lit longer, increasing the risk of a crash. The affected vehicles are equipped with a diesel engine and Hydroboost brake system, which uses power-steering pressure for brake assist.
Chrysler will notify owners in February 2011, and dealers will replace the reservoir cap for free. For more info, owners can call Chrysler at 800-853-1403 or NHTSA’s hot line at 888-327-4236.
