Crimp points in the brake boosters of the Jeep Grand Cherokee and Dodge Durango SUVs from 2011 and 2014 model years can corrode if they're exposed to water. If the water freezes, the boosters won't help with braking as per usual, Chrysler officials said.
Chrysler began looking into the issue after receiving customer complaints. The company knows of one accident with no injuries.
Chrysler is expected to notify customers who own the affected models. Dealers will install a shield to protect the boosters for free and replace boosters that aren't working properly.
