Chronology :

On May 1, 2024, Bendix (the PVM supplier) notified DTNA that it had determined a safety-related defect existed in certain PVMs using a rubber ball seal sourced from a specific sub-supplier and on May 8, 2024, DTNA decided to conduct a recall based on the supplier’s safety defect determination. Prior to this notification from the supplier, in late December 2023, FCCC became aware of a possible quality issue with the Bendix PVM and in January 2024, DTNA started an investigation for any field impacts to safety and requested information from Bendix directly in order to support its review. As DTNA had not received information from Bendix, it proceeded to review the issue internally and did not identify any risk to motor vehicle safety. In late April 2024, Bendix advised FCCC to quarantine parts and Bendix advised DTNA of its decision to conduct a recall shortly thereafter. DTNA has not received reports of any field occurrences of PVM failures related to this issue.
