The issue is unrelated to the 500e’s electric powertrain. Half shafts transfer torque from a vehicle’s gearbox to its wheels.

An investigation was launched after Chrysler Group learned a customer’s vehicle exhibited power loss. Engineers discovered two assembly steps had not been properly completed, thereby creating a condition that could lead to half shaft separation.

Chrysler Group is unaware of any related accidents or injuries.

Customers will receive free rental vehicles while their vehicles are being repaired at no charge.

Vehicles on dealer lots also are affected. Chrysler Group will advise the National Highway Traffic Safety Administration when the precise recall population is determined.
