Chronology :

On 8-6-2021, Shyft was contacted by ZF to inform us of the potential for approximately 87 power steering pumps that may have been subject to a machining defect which may cause pressure to build in the pump and the shaft seal. This condition could cause power steering fluid to leak into the engine and result in a loss of power steering assist. ZF further asserted this would be an infantile failure. Upon notice, Shyft began a review of warranty data and customer complaints in an effort to identify complaints involving loss of power steering assist. Although none were identified, there were two claims involving power steering fluid leaking into the engine oil. Further, production information was pulled then compared to purchase order and receipt history.

From there 90 VIN’s were identified that potentially would be equipped with the suspect pumps. From the warranty and customer complaint history, one power steering pump was retrieved from the complainant and an analysis by ZF, provided on 8-31-2001, pump seal failed due to a separate cause. The second pump has not been returned for analysis. On 9-14-2021, in discussion with ZF, they could not identify what changed, and when, in their process to result in the machining defect. (e.g. a gradual change or sudden change) On 9-16-2021, a discussion with ODI occurred on the matter and on 9-20-2021, in an overabundance of caution, Shyft elected to issue a safety related recall.
