Jaguar Land Rover (JLR) has announced a significant recall affecting more than 170,000 vehicles in the United States, following concerns over a defect that could lead to a sudden loss of drive power. The recall, disclosed on April 23, 2026, was reported by the US National Highway Traffic Safety Administration (NHTSA) and represents one of the largest safety actions involving the British automaker in recent years.
According to regulatory filings and reporting, the recall covers approximately 170,169 vehicles across several of JLR’s core product lines. Affected models include various versions of the Jaguar E-Pace, F-Pace, Land Rover Defender, Discovery, Range Rover, Range Rover Sport, and Discovery, all of which form the backbone of the company’s global SUV portfolio.
The issue has been traced to a failure in the vehicles’ DC-DC converter, a critical component responsible for maintaining the 12-volt electrical system. When functioning correctly, this system supports essential vehicle operations, including power management and auxiliary systems. However, a fault in the converter can prevent the 12-volt battery from charging, which in turn may result in a complete loss of propulsion as well as the failure of exterior lighting systems.
Regulators have indicated that this type of failure presents a clear safety concern. A sudden loss of drive power, particularly at highway speeds, increases the risk of a crash, especially if it occurs without warning. The potential loss of exterior lighting compounds the risk, reducing vehicle visibility to other road users in low-light conditions.
Further technical details suggest that the fault may originate from an internal issue within the converter’s control electronics, specifically a microchip responsible for regulating voltage. If this component fails, the entire low-voltage system may shut down, triggering the cascade of failures described in the recall documentation.
At the time of the announcement, Jaguar Land Rover had not yet finalized a remedy for the defect. The NHTSA confirmed that a solution is still under development, and affected owners are expected to be notified once a fix has been approved and made available through authorized dealers.
This recall comes at a time when JLR has been navigating a range of operational and market challenges. The company, owned by India’s Tata Motors, has recently reported fluctuations in production and sales, influenced by factors such as supply chain disruptions, a prior cyberattack, and shifting global demand. The affected vehicles—particularly the Range Rover, Defender, and Range Rover Sport—are among the brand’s most profitable and strategically important models, making the recall notable not only from a safety perspective but also in terms of potential brand impact.
Jaguar Land Rover has yet to announce a timeline for the rollout of repairs, but the company is expected to work closely with regulators to address the issue and minimize risk to drivers. Until then, the recall remains under active investigation, with further updates likely as a technical solution is finalized and implemented.
