Service bulletin B320123

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.

After prolonged straight-ahead driving (e.g. highway driving), there may be a temporary, slightly noticeable increase in steering forces when steering out of the steering wheel center position. This minimally noticeable increase in steering forces is perceived as a slight, brief resistance. After overcoming this brief resistance when steering out of the steering wheel center position, no permanent increase in steering forces is noticeable.
