## NHTSA's summary

Motiv Power Systems, Inc. has determined that on certain vehicles converted to a Motiv Gen 5 EPIC \(E\-450, F\-59, F\-53 models\) powertrain, the vehicle control software could misclassify a loss of isolation between the chassis and high voltage system during operation. This in turn could result in a loss of vehicle propulsion and power\-assistance for steering and braking.
