Jaguar Land Rover (JLR) is recalling 23,677 vehicles in the United States after identifying another potential problem with the electrical systems in several of its hybrid SUVs. The defect could cause vehicles to lose drive power and exterior lighting, increasing the risk of a crash.
The September 2026 recall involves nine Jaguar and Land Rover model ranges fitted with the manufacturer’s 48-volt hybrid system. It follows a larger recall issued in April 2026 for a similar problem involving the DC-DC converter, which is responsible for maintaining the vehicle’s 12-volt electrical system.
What is the problem?
The latest recall concerns a possible malfunction in the DC-DC converter. This component transfers electrical energy from the vehicle’s high-voltage hybrid battery to its conventional 12-volt system, which supports essential functions including vehicle electronics and exterior lighting. However, documents filed with the National Highway Traffic Safety Administration (NHTSA) indicate the converter can experience an electrical overload during periods of high power demand. A separate software error may also prevent it from operating correctly when the vehicle starts.
If the converter stops working, the 12-volt battery may no longer receive a charge, and as its available power decreases, the vehicle could eventually lose drive power altogether. Exterior lighting may also stop functioning, creating additional hazards for the driver and other road users.
Affected drivers may receive dashboard warnings instructing them to stop the vehicle safely. However, the potential for a complete loss of propulsion means the problem could become particularly dangerous if it develops while driving at speed. JLR received 393 claims and field reports relating to the issue between April and September 2026.
What owners should know
The recall affects the following model years:
- 2019-2024 Range Rover Sport
- 2020-2024 Range Rover
- 2020-2024 Range Rover Evoque
- 2020-2024 Land Rover Discovery Sport
- 2020-2024 Land Rover Defender
- 2021-2024 Range Rover Velar
- 2021-2024 Land Rover Discovery
- 2021-2024 Jaguar E-Pace
- 2021-2024 Jaguar F-Pace
The campaign covers 23,677 vehicles and expands on the April 2026 recall, which affected 170,169 JLR vehicles over an earlier DC-DC converter concern, and JLR dealers will install a software update at no cost to owners.
The update is intended to improve electrical load balancing and address the software fault that could prevent the converter from operating at startup. It will also introduce a limp-home mode designed to provide a warning if the converter goes offline.
Owner notification letters are scheduled to be sent by November 13, 2026, and owners can check their vehicle identification number through the NHTSA recall database to establish whether their vehicle is included.
If your Jaguar or Land Rover has experienced electrical problems
Sudden power loss can leave drivers vulnerable, especially when it affects a vehicle’s ability to maintain propulsion or operate its exterior lights. Owners who have experienced electrical warnings, unexpected shutdowns, or repeated converter problems should keep records of dealership visits, diagnostic reports, and repair costs.
If your vehicle has suffered recurring electrical failures or has spent significant time out of service because of these problems, The Lemon Firm can examine the history of the fault and help determine whether your experience raises concerns beyond the recall itself.
