Jaguar Land Rover recalls 23,000 SUVs that can lose power and exterior lights

Jaguar Land Rover has expanded a safety recall to include 23,677 SUVs in the United States after federal regulators identified an electrical fault that can cut drive power and exterior lighting. The defect concerns a DC-to-DC converter, a component that transfers power from a vehicle’s high-voltage battery to its conventional 12-volt electrical system. The company estimates that every vehicle in the recall population may be affected, according to an independent report on the campaign.

The practical hazard is unusually broad. A converter failure can leave the vehicle without 12-volt charging, and the resulting loss of power can affect both the ability to drive and the exterior lights other road users rely on to see a vehicle and read its signals.

The DC-to-DC Converter Sits Between Two Electrical Systems

Modern hybrid and electric-capable vehicles commonly carry two separate electrical systems. A high-voltage lithium-ion battery supplies propulsion-related energy, while a 12-volt battery supports familiar equipment such as lights, electronics and accessories. The DC-to-DC converter is the bridge between them: it lowers high-voltage direct current so that the smaller battery can be charged and the lower-voltage system can keep operating.

In the affected Jaguar Land Rover vehicles, the National Highway Traffic Safety Administration says an electrical overload during periods of high power demand can cause the converter to malfunction. A separate software error can also prevent the unit from functioning when the vehicle starts. The agency’s notice describes the consequence plainly: failure of the converter can lead to loss of 12-volt system charging, complete loss of drive power and loss of exterior lighting.

That sequence explains why the recall is more serious than a dashboard-message fix. A warning light is inconvenient; a power loss while a vehicle is moving can change how a driver controls it. Losing exterior lights at the same time can make the vehicle harder for nearby motorists to identify, particularly in poor weather or after dark.

Nine Jaguar and Land Rover Model Lines Are Included

The 23,677-vehicle total covers several model years and nameplates. The listed vehicles are 2021-2024 Range Rover Velars, 2019-2024 Range Rover Sports, 2020-2024 Range Rover Evoques, 2020-2024 Range Rovers, 2021-2024 Jaguar F-Paces, 2021-2024 Jaguar E-Paces, 2020-2024 Discovery Sports, 2021-2024 Discoverys and 2021-2024 Land Rover Defenders.

That is a wide group because the relevant question is not whether an SUV carries one particular badge. It is whether it has the high-voltage and 12-volt arrangement covered by the recall and the converter/software combination named in the federal filing. Owners should use a vehicle identification number lookup rather than relying only on model year or a model name, since a recall population can be narrower than every vehicle sold under a particular label.

Jaguar Land Rover reported 393 U.S. claims and field reports associated with the issue to NHTSA. The source says no accidents, injuries or fires had been reported in connection with the defect at the time of the notice. That absence is important context, but it is not a reason to ignore a recall: the purpose of a safety campaign is to correct a known failure mode before it produces a crash or injury.

The Planned Software Update Adds a Limp-Home Warning

Dealers will update the vehicles’ software at no charge. Jaguar Land Rover’s planned update is intended to introduce a limp-home mode, giving a driver a warning if the DC-to-DC converter goes offline rather than leaving the loss of electrical support entirely unannounced. A limp-home setting is not a cure for a failed converter; it is a strategy for giving the driver enough notice to reduce speed and get the vehicle to a safer location.

The recall source distinguishes between an interim notice and the completed repair campaign. Interim owner letters warning of the safety risk are expected to be mailed November 13. Additional letters are expected once the final remedy is available. Owners who receive an interim letter should keep it, check the VIN against the official recall record, and follow the manufacturer’s directions rather than assuming a software update has already been installed.

Dealership service is the central remedy because recall work is tied to a specific vehicle and campaign. A generic software update or routine service visit does not prove the recall has been closed. The service record needs to show that the applicable recall remedy was performed on that vehicle.

Why Power and Lighting Failures Raise the Same Safety Concern

Drive power and exterior lighting sound like separate systems, but the converter fault links them through the 12-volt network. When that network no longer receives charge from the high-voltage battery, the vehicle can lose functions that depend on the smaller battery even while the larger battery still holds energy. The fault therefore has the potential to turn a problem in an electrical conversion component into a visibility and mobility problem at once.

The safest next step for a covered owner is to confirm the vehicle’s status through the official recall lookup and arrange the dealer remedy when it is offered. NHTSA’s finding and Jaguar Land Rover’s campaign are specific to the named vehicles and defect; they do not establish that every Jaguar or Land Rover SUV has the same problem. The immediate fact is narrower, but serious: 23,677 listed SUVs are subject to a recall over a failure that can remove both drive power and exterior lights.
