PROBLEM

Show/hide table

This Product Improvement Program is a Safety recall in accordance with the US National Traffic and Motor Vehicle Safety Act and the Canadian Motor Vehicle Safety Act. The extension pipe attached to the Aftertreatment Regeneration Device (ARD) may develop a crack or hole and heat and flame may escape during a regeneration of the Diesel Particulate Filter, which may result in a fire hazard. This PIP identifies the final remedy repair and notifies the customer that the final remedy is available.

It is a violation of US Federal law for a dealer to deliver a new motor vehicle or new or used engine covered by this Safety PIP until the PIP has been completed.
