Ford has issued a recall that affects the C-Max Energi.
The recall actually includes the 2015 Focus, C-Max and Escape vehicles, but the C-Max Energi is the only plug-in affected.
According to reports there's an issue with a body control module that could allow the engine to continue running even after being properly shut off.
The C-Max Energi has a push-button start, but even Fords with a standard keyed ignition are affected by this problem.
Here's a rundown of the affect vehicles:
Focus models built in the Wayne, Mich., assembly plant from June 17, 2014 to June 12, 2015, C-Max hatchbacks built in the same plant between April 22, 2014 and June 12, 2015, and Escapes built in Louisville from April 1, 2014 to June 12, 2015 make up the roughly 433,000 vehicles affected.
Ford is contacting owners of affected models and will be replacing the modules free of charge.
