Service bulletin 143

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 MDPS (motor driven power steering) assembly contains a flexible rubber coupling which may wear over time resulting in a slight "clicking" or "thud" type noise when turning the steering wheel. The warranty coverage for this coupling has been extended to 10 years from the date of original retail delivery or date of first use or 100,000 miles, whichever occurs first. This bulletin describes the service procedure to replace the coupling. Refer to the warranty and service parts information outlined in this bulletin whenever MDPS coupling replacement is required.
