Jaguar Land Rover recalls 170,000 cars

Jaguar Land Rover is recalling 170,169 U.S. vehicles after a fault in the mild-hybrid electrical system was linked to sudden loss of drive power. (nhtsa.gov) (reuters.com) The problem sits in a DC-DC converter, a box that turns power from the 48-volt mild-hybrid system into electricity for the 12-volt battery that runs key vehicle functions. Jaguar Land Rover told the National Highway Traffic Safety Administration that a fault in the converter’s boost-control microchip can stop that charging. (nhtsa.gov) (autos.yahoo.com) If that happens, the 12-volt battery can drain until the vehicle loses motive power and exterior lighting, according to the federal recall filing. The safety report lists the estimated defect rate in the recall population at 100%. (nhtsa.gov) The recall covers nine model lines across Jaguar and Land Rover brands, including the Jaguar E-Pace and F-Pace, plus the Defender, Discovery, Discovery Sport, Range Rover, Range Rover Evoque, Range Rover Sport and Range Rover Velar. Model years run from 2019 through 2024 depending on the vehicle. (nhtsa.gov) (autos.yahoo.com) The largest slice is the 2019-2024 Range Rover Sport at 61,616 vehicles, followed by the 2020-2024 Range Rover at 34,930 and the 2020-2024 Defender at 24,710. The filing also lists 5,304 Range Rover Velars and 2,994 Range Rover Evoques. (nhtsa.gov) Jaguar Land Rover filed the recall on April 17, 2026, and the National Highway Traffic Safety Administration acknowledged it on April 22. Reuters reported the action publicly on April 23. (nhtsa.gov 1) (nhtsa.gov 2) (reuters.com) Jaguar Land Rover said in the filing that it does not yet have a remedy. Owners will need to wait for a later notice telling them when dealers can complete repairs. (nhtsa.gov) (motor1.com) This is not the first time JLR has dealt with DC-DC converter issues in its mild-hybrid vehicles. Earlier technical bulletins and a 2020 update-before-sale campaign also addressed converter behavior in Land Rover models, though this 2026 action is far broader. (nhtsa.gov 1) (nhtsa.gov 2) (nhtsa.gov 3) For owners, the immediate step is simple: check the vehicle identification number in the federal recall database and watch for the manufacturer’s notice. The opening problem is unchanged until Jaguar Land Rover publishes the fix. (nhtsa.gov 1) (nhtsa.gov 2)
