Service bulletin R51

A bulletin is a manufacturer's communication to its dealers, as NHTSA indexes it. The summary is NHTSA's. The document is the manufacturer's: read it at NHTSA. A bulletin is not a recall, and listing a model year does not mean every vehicle of it is concerned.

NHTSA's summary

The Charge Air Cooler (CAC) on about 7,600 of the above vehicles may develop internal icing in cold temperature regions. This condition may cause the Malfunction Indicator Light (MIL) to illuminate and cause the vehicle to experience a 35 mph limp in condition. A winter front cover must be installed when sustained day and night time temperatures drop below 30° F (-1° C).
