Service bulletin 18276

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

18276 - Customer Satisfaction Program - Certain vehicles, may have a condition in which the power steering assist power pack is potentially missing ?welds? between the circuit board and the motor. If this condition exists, power steering may be lost, and the driver may experience unanticipated increased steering effort as the vehicle reverts to manual steering. A chime will also sound in the vehicle, and a ?Service Power Steering? message will appear on the Driver Information Center (DIC). Manual steering functionality will be maintained but will require additional effort, particularly at lower speeds. Dealers are to replace the complete power steering rack assembly

18207 012022-05-31. Service bulletin. Customer Satisfaction. Certain vehicles may have a condition in which the power steering gear motor could separate from the steering gear housing due to corrosion of the attaching bolts. If the motor separates, power steering assist may be reduced or lost, and the driver may experience an unexpected increase in steering effort, especially at low speeds. Replace the bolts that attach the electric power steering motor to the steering gear and add a protective wax coating to each bolt and the seam around the electric power steering motor. If the bolts cannot be removed due to corrosion, the steering gear must be replaced. ** Revised Parts Information **
