Jaguar Land Rover (JLR) has issued another JLR SUV recall covering 23,677 of its vehicles in the United States due to an error in a software program that may create issues with a DC-DC converter as part of its 48-volt hybrid system. According to documentation submitted to the National Highway Traffic Safety Administration (NHTSA), at times this failure of the converter can cause the loss of electricity to the vehicle and ultimately result in the loss of all external lighting.
The recall covers several Land Rover and Jaguar models, including the Defender, Discovery, Range Rover, Range Rover Sport, Range Rover Evoque, Range Rover Velar, Discovery Sport, F-Pace, and E-Pace.
The issue arises when a dc-dc converter has a large amount of electrical demand (load) on it and cannot effectively manage that load. Once the converter shuts off, the vehicle will run only as long as there is enough battery power left to operate the engine and headlights.
Which Land Rover and Jaguar Models Are Recalled?
The latest JLR SUV recall covers vehicles from several model years:
- Land Rover Discovery Sport: 2020–2024
- Range Rover Evoque: 2020–2024
- Range Rover: 2020–2024
- Land Rover Defender: 2020–2024
- Jaguar E-Pace: 2021–2024
- Jaguar F-Pace: 2021–2024
- Range Rover Velar: 2021–2024
- Land Rover Discovery: 2021–2024
- Range Rover Sport: 2019–2024
The number of affected vehicles varies widely between models. JLR has identified 10,973 Range Rover Sport vehicles and 8,100 Land Rover Defenders in the recall population.
The Range Rover has 3,849 affected vehicles, while 552 Land Rover Discovery SUVs are included.
At the other end of the list, only three Discovery Sport vehicles are part of the recall. The Jaguar E-Pace accounts for 10 vehicles, while 35 Range Rover Evoques, 76 Range Rover Velars, and 79 Jaguar F-Paces are included.
What Is Causing the Problem?
The problem behind the JLR SUV recall centers on the DC-DC converter used with JLR’s 48-volt hybrid system.
These vehicles use a 48-volt electrical system alongside their gasoline engines. The system supports functions such as improved fuel efficiency and additional electrical assistance during acceleration. The DC-DC converter helps manage the different voltage levels required by the vehicle’s electrical components.
According to NHTSA documents, the affected vehicles can experience excessive electrical demand when the system is operating under high-load conditions. Insufficient load balancing can allow the converter to become overloaded.
JLR’s investigation also identified a software bug that could cause the converter to go offline during vehicle startup.
That means the latest problem is different from the hardware-related issue addressed in an earlier recall, even though both involve the same component.
This Follows a Much Larger JLR Recall
The current JLR SUV recall involves a smaller group of vehicles from a much larger recall announced in April 2026.
That earlier recall covered 170,169 vehicles across JLR’s lineup and involved a similar DC-DC converter failure. The initial repair addressed hardware-related problems with the converter.
JLR’s subsequent investigation found that software could create another path to a similar overload condition. The investigation also identified the startup software bug that could cause the converter to shut down.
The latest recall therefore focuses on correcting the software rather than replacing the converter hardware.
What Happens If the Converter Fails?
A failure covered by the JLR SUV recall can produce warning messages or warning lights telling the driver to stop when it is safe to do so.
As the vehicle’s battery loses charge, the electrical system can eventually become unable to maintain normal operation. The vehicle may then coast to a stop and lose its exterior lighting.
The combination of a potential loss of propulsion and exterior lighting creates a safety concern, particularly if the problem occurs while the vehicle is being driven.
JLR has not reported any injuries or crashes connected to the latest issue.
Between April and September 2026, the company received 393 claims and field reports related to the problem behind the JLR SUV recall, according to the recall information submitted to NHTSA.
How Will JLR Fix the Recall?
JLR dealers will address the JLR SUV recall by installing a software update on affected vehicles at no cost to owners.
The update is designed to improve electrical load balancing when the 48-volt system is under heavy demand. It will also correct the software bug that can cause the DC-DC converter to go offline during startup.
The update will also add a “limp home” mode that can activate if the converter goes offline. This is intended to help the vehicle continue operating under the fault condition rather than simply losing normal drive capability.
Owners of affected vehicles are expected to receive recall notifications by November 13, 2026.
Owners who receive a notice should contact an authorized JLR dealer to arrange the software update. The repair will be performed free of charge.
Land Rover Defender Owners Are Among Those Affected
The JLR SUV recall includes 8,100 Land Rover Defender vehicles, making it one of the larger groups of vehicles being recalled under this program. A number of JLR models utilize the 48-volt hybrid system being addressed through the campaign.
In addition to the Defender, Range Rover Sport owners represent the largest group of owners who could have been impacted by the issue at hand. There are 10,973 Range Rover Sports that were identified as possibly affected. Owners can check their vehicle identification numbers (VINs) against the official recall information to determine if their vehicle falls into the group of vehicles covered by the recall. The fact that a vehicle was identified as being in an affected model or model year range means that it has been identified as falling into the population of vehicles that JLR believes may be susceptible to the software-related issue.
What Owners Should Do
Owners who receive a recall notice should follow the instructions provided by JLR and schedule the software update with an authorized dealer.
If warning messages related to the electrical or hybrid system appear while driving, the recall information advises drivers to stop when it is safe to do so.
The repair does not require owners to pay for the software update. JLR will handle the recall repair through its authorized dealer network at no charge.
The latest campaign shows how a component-related recall can expand after additional investigation identifies a separate software issue. In this case, JLR’s initial hardware fix addressed one source of DC-DC converter problems, while the newer recall targets software-controlled electrical load management and a startup fault.
