There is a risk that the brake booster water shield may be incorrectly installed. This may result in limited braking ability due to water ingress into the brake booster.

Fix: On affected vehicles the brake booster water shield must be inspected for proper installation. If the brake booster water shield is found to be missing or incorrectly installed the brake booster must also be vacuum tested. Brake boosters that do not pass the vacuum test must be replaced. At the conclusion of this the brake booster must be equipped with a properly installed shield to protect the brake booster crimp joints from water exposure.

Recalled models: GRAND CHEROKEE · 1,770 vehicles

It is possible that during the manufacturing process the coating on the Occupant Restraint Control (ORC) printed circuit may not have been applied correctly. If the coating has been applied incorrectly it can result in lead salts forming which can cause a resistive short across the ORC module printed circuit board(s). Atmospheric humidity may increase the potential for this condition to occur. Should this occur then it will cause the airbag warning lamp to illuminate and potentially disable the passive restraint system. Ultimately this can result in an inoperative passive restraint system (airbag) which could increase the risk of injury in the event of a collision.

Fix: Recall all affected vehicles to replace the ORC module.

Recalled models: GRAND CHEROKEE · 1,069 vehicles

The brake booster may prematurely corrode. If perforation of the brake booster shell (due to corrosion) occurs water could enter the brake booster during wet weather. In very cold weather the water may freeze. The driver may be required to apply additional application force to the brakes during sub-freezing driving conditions leading to an additional brake pedal application force requirement which could slow the driver's brake application reaction time and cause a crash.

Fix: Recall the vehicles that are likely to be affected to check the brake booster for corrosion and where necessary replace the brake booster. In all cases a shield to protect the brake booster crimp joints from water exposure will be fitted.

Recalled models: GRAND CHEROKEE · 2,420 vehicles
