The defect
THE INVOLVED VEHICLES ARE IN NON-COMPLIANCE TO FEDERAL MOTOR VEHICLE SAFETY STANDARD NO. 121, "AIR BRAKE SYSTEMS", DUE TO OMISSION OF A SUFFICIENT AIR RESERVOIR CAPACITY AND A QUICK RELEASE VALVE IN CONJUNCTION WITH THE PINTLE HOOK. LACK OF AIR RESERVOIR CAPACITY COULD, IN A PANIC STOP SITUATION AT HIGH SPEED OR ON A SHARP INCLINE, CAUSE ALL OF THE AIR TO BE RELEASED BEFORE THE VEHICLE IS BROUGHT TO A COMPLETE STOP. ALSO, LACK OF THE QUICK RELEASE VALVE DELAYS THE REACTION TIME BEYOND ACCEPTABLE LIMITS.
The remedy
THE DEALER WILL INSTALL THE MISSING COMPONENTS, FREE OF CHARGE.
