Service bulletin G-206405

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.

THE VEHICLE MAY REVERT TO MANUAL STEERING WHICH REQUIRES GREATER DRIVER EFFORT, PARTICULARLY AT LOW VEHICLE SPEEDS. DEALERS ARE TO FLUSH THE POWER STEERING SYSTEM, REPLACE THE POWER STEERING PUMP, AND IF IT HASN'T ALREADY BEEN REPLACED, INSTALL A NEW STEERING GEAR VALVE HOUSING.
