Chrysler recalls 868K SUVs to install brake booster shield Chrysler Group announced it will recall an estimated 867,795 SUVs to install a shield that protects their brake boosters from corrosion caused by undue water exposure. Chrysler will inspect the brake boosters on certain Jeep Grand Cherokee and Dodge Durango SUVs, model years 2011-2014. The boosters may be replaced if their capability has been reduced.Chrysler launched an investigation after receiving customer feedback about excessive brake-pedal firmness. The investigation discovered certain vehicles have brake boosters with small crimp joints; and these joints may exhibit corrosion when exposed to water. Should water enter the boosters through corroded joints – a previously unseen occurrence – brake function may be compromised if the water freezes. Chrysler is aware of one related accident and no injuries.
