The Problem: Chrysler Group received feedback from customers that brake pedal feel in the 2011-2014 Jeep Grand Cherokee and Dodge Durango became harder than normal, meaning it required pushing harder to stop the vehicles. If small crimped joints leading to the brake booster system rust over time, that can increase brake pedal firmness. If the corrosion leads to minute gaps in the joints, water could enter the gaps. It cold weather, the water could freeze and further inhibit brake operation. Chrysler says it has reports of one accident due to this problems, but says the accident didn’t result in any injuries. Even though a firmer pedal could make it harder for drivers to stop the vehicle, Chrysler says that the Jeep Grand Cherokee and Dodge Durango still meet all federal standards for braking performance.
The Fix: Chrysler will inspect the brake boosters on the 2011-2014 Jeep Grand Cherokee and Dodge Durango, and replace them if the crimp joints have rusted. Regardless of corrosion, Chrysler will install a new shield to protect the joints from water. On new models, Chrysler applies an anti-corrosion coating to all the crimp joints and hosing, preventing this problem on future models.
