The power brake booster in these vehicles uses vacuum developed by the engine to provide power assistance to the braking system. Certain vehicles are being recalled because the shell of the vacuum brake booster can corrode and allow water to get inside. The water inside could freeze and limit ability of the brake booster to provide brake assistance. This reduced braking ability can increase the risk of a crash. Dealers will test the brake booster and replace those that fail, and all vehicles will have a diverter shield installed on the brake booster to prevent this from occurring in the future.
2012 Jeep Grand Cherokee Recalls
Certain vehicles equipped with the Ready Alert Braking (RAB) System are being recalled because the brake pedal may feel harder that normal when the driver applies the brakes. As a result, the driver may not press the brake pedal as hard as necessary to achieve a normal distance. An increased stopping distance increases the risk of a crash. Dealers will update the ABS control module software to correct this concern.
667 vehicles equipped with a 3.6L engine are being recalled because a connecting rod bearing can fail due to debris inside the engine block.
