What is wrong
THE INVOLVED VEHICLES MAY NOT COMPLY WITH FEDERAL MOTOR VEHICLE SAFETY STANDARD NO. 121, "MODULATED EMERGENCY BRAKING". THE "O" RINGS IN THE SHUTTLE VALVE MAY DEVELOP SLIGHT LEAKS IN COLD WEATHER. IN ADDITION, NEOPRENE WASHERS USED ON THESE "O" RINGS MAY EVENTUALLY EXPAND OR PUCKER IN COLD CLIMATES, MAKING IT POSSIBLE FOR THE SHUTTLE PISTON TO BECOME TRAPPED BY THE INNER-CIRCUMFERENCES OF THE WASHERS. THIS WOULD FORCE THE EMERGENCY BRAKES TO THE "ON" POSITION AND WOULD PREVENT THEM FROM BEING RELEASED.
The fix
Recall repairs are free of charge.
THE DEALER WILL REPLACE THE TWO NEOPRENE WASHERS WITH GLASS FILLED TEFLON WASHERS THAT WILL NOT BE AFFECTED BY COLD CLIMATES.

A recall means the maker found a safety problem and offers a free fix; it does not mean every unit has the problem. Units affected are as reported by the company. Popular models sell more and so have more recalls and complaints. Official public data; texts are shortened. A dealer can tell whether a single vehicle still needs the repair.
