2014 Jeep Grand Cherokee. Consumer writes in regards to vehicle braking problems. The consumer stated water entered the brake booster, which caused it to freeze and reduced braking performance. Chrysler stated there was corrosion problem with the brake booster caused by a small amount exposed, uncoated surface at the crimp joints, that allowed water to enter the booster and freeze.
