Chrysler has submitted a noncompliance report with the NHTSA containing details of a safety defect that could affect braking in certain 2011-2014 Dodge Durango and 2011-2014 Jeep Grand Cherokee vehicles. The problem will have approximately 644,354 owners returning their SUV’s to a manufacturer approved repair facility to have them tested and repaired as necessary.

According to the recall report, some Jeep Grand Cherokee and Dodge Durango vehicles may have a small amount of exposed uncoated surface at the crimp joints on the brake booster. The exposed surface could corrode, allowing water to enter the booster and freeze in cold climates. Drives may experience limited braking ability, increasing the chance of an accident.

Dealerships will inspect and test the booster to confirm it is able to hold an acceptable vacuum and will add a water diverter shield to the booster or replace defective parts as necessary. Owners wanting more information about the problem can contact Chrysler at 1-800-853-1403. Chrysler’s recall number is P14 and the NHTSA campaign number is 14V-154.
