Service Bulletin - The brake tandem motor cylinder on certain vehicles may only operate in failsafe mode if saltwater (in areas where road salt is used) enters the brake tandem motor cylinder and corrodes its metal components. The saltwater is able to enter the motor due to small gaps in the motor cover that result from issues in the manufacturing process. If the brake tandem motor cylinder enters into failsafe mode, instrument panel indicators will come on to alert the driver and there will be an increase in brake pedal travel during braking.
