What is wrong
THE INVOLVED VEHICLES CONTAIN EMISSION CONTROL SYSTEMS THAT UTILIZE A PULSE AIR REED VALVE TO PERMIT AIR FLOW FROM THE AIR CLEANER TO THE EXHAUST MANIFOLD ON NEGATIVE PRESSURE PULSATIONS. THESE REED VALVES MAY FAIL UNDER COLD WEATHER CONDITIONS, CAUSING A BACKFLOW OF EXHAUST GAS INTO THE AIR CLEANER AND FUEL INDUCTION SYSTEM ON POSITIVE EXHAUST PULSES. THIS CAUSES AN OVERLY RICH AIR/FUEL MIXTURE, REDUCED FUEL ECONOMY AND REDUCED ENGINE PERFORMANCE. CONTINUED VEHICLE OPERATION MAY RESULT IN ENGINE STALLING OR OVERHEATING OF THE EXHAUST SYSTEM.
The fix
Recall repairs are free of charge.
THE DEALER WILL REPLACE THE PULSE AIR SYSTEM REED VALVE AND SILENCER WITHOUT CHARGE.

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.
