• Jaguar Land Rover is recalling 23,677 SUVs with 48-volt hybrid systems due to malfunctions that could cause a loss of drive power and exterior lighting, according to NHTSA documents.
• This is a smaller group of vehicles within the nine models that were recalled in April 2026 for a similar DC-DC converter failure.
• JLR dealers will install a software update in affected vehicles to ensure adequate load-balancing in high-demand instances and fix a bug.

Jaguar Land Rover is recalling 23,677 vehicles across nine model ranges that feature JLR’s 48-volt hybrid system. The affected SUVs’ DC-DC converter can experience an electrical malfunction that could cause a loss of drive power and external lighting, according to documents filed with the National Highway Traffic Safety Administration (NHTSA).

Recalled vehicles include the 2020–2024 Land Rover Discovery Sport, Range Rover Evoque, Range Rover, and Land Rover Defender; the 2021–2024 Jaguar E-Pace, Jaguar F-Pace, Range Rover Velar, and Land Rover Discovery; and the 2019–2024 Range Rover Sport.

This is a smaller pool of the same models involved in an April 2026 recall filed with the NHTSA, which listed a similar DC-DC converter problem. That recall affected 170,169 vehicles across JLR’s inventory. While the first fix solved the hardware-related issues with the converter, new NHTSA documents say an investigative committee, along with an AI model, discovered that a software issue could cause similar overloads. The committee also found a software bug that could cause the converter to go offline at startup.

JLR vehicles with the 48-volt hybrid system use electric batteries alongside gas engines to improve fuel economy and provide extra power while accelerating. The DC-DC converters help convert and balance voltage levels within the hybrid system.

Affected vehicles may experience a DC-DC converter failure and overloaded current during times of high demand due to insufficient electrical load balancing. Vehicles with the failed converter will see warning lights urging the driver to stop when safe. As the battery loses charge, the vehicle will eventually coast to a stop and lose its exterior lighting.

The smallest pool of recalled models is the Land Rover Discovery Sport, with just three affected vehicles. Models with a smaller volume of recalls also include 10 Jaguar E-Paces, 35 Range Rover Evoques, 76 Range Rover Velars, and 79 Jaguar F-Paces.

Owners of the Land Rover Discovery, Range Rover, Range Rover Sport, and Land Rover Defender are most likely to be involved in the recall. JLR has identified 552 Discovery, 3849 Range Rover, 8100 Defender, and 10,973 Range Rover Sport models with potential for a failed converter.

Between April and September 2026, JLR has received 393 claims and field reports about the issue, but no injuries or accidents have been reported. At no cost to the owner, dealers will install a software update that corrects the software bug and introduces a “limp home” mode that will kick in if the DC-DC converter goes offline. Owners of identified vehicles will be notified by November 13, 2026.
