Jaguar Land Rover expanded an existing recall to include an additional 23,677 vehicles over an electronic system error that may lead to the loss of drive power and exterior lighting, according to federal regulators.
About 23,677 vehicles are affected by the recall, including 2021-2024 Land Rover Range Rover Velar, 2019-2024 Land Rover Range Rover Sport, 2020-2024 Land Rover Range Rover Evoque, 2020-2024 Land Rover Range Rover, 2021-2024 Jaguar F-Pace, 2021-2024 Jaguar E-Pace, 2020-2024 Land Rover Discovery Sport, 2021-2024 Land Rover Discovery and 2020-2024 Land Rover Defender models.
The recall was initiated because a DC-DC converter may malfunction due to an electrical overload that can happen during high power demand, the National Highway Traffic Safety Administration (NHTSA) said in its recall notice.

A software error can also cause the converter to stop functioning at vehicle start-up, which may result in the loss of drive power and exterior lighting.
“Failure of the DC-DC converter will result in the loss of 12-Volt system charging and can lead to complete loss of drive power and exterior lighting,” the notice reads.
Jaguar Land Rover estimates that all the listed vehicles are affected by the defect.

The affected vehicles use a high-voltage battery system alongside a conventional 12-volt battery that powers systems such as lighting and electronic accessories. The DC-DC converter charges the 12-volt battery from the high-voltage system.
The lithium-ion battery is charged at a charging station, and the lead battery is charged with power from the lithium-ion battery, according to Panasonic. As the lithium-ion battery is charging, a DC-DC converter converts high-voltage DC power into low-voltage DC power.
Jaguar Land Rover has received 393 claims and field reports about the issue in the U.S., according to the NHTSA.

No accidents, injuries or fires have been reported.
Dealerships will update the vehicle software at no cost. The update will introduce a new “limp-home” mode, providing a warning to the driver in case the DC-DC converter goes offline.
Interim letters notifying owners of the safety risk are expected to be mailed on Nov. 13. Additional letters will be sent out once the final remedy is available.
