This Product Improvement Program is a Safety Recall in accordance with the US National Motor Vehicle Safety Act and the Canadian Motor Vehicle Safety Act. Cooling system coolant in this application can degrade, which may cause engine components to prematurely deteriorate and a coolant leak could be experienced. If coolant leaks are observed, they should be immediately remedied. Failure to remedy a coolant leak, in conjunction with other factors or circumstances, may create the potential for a crash hazard.
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.
