Jaguar Land Rover North America, LLC (Land Rover) is recalling certain 2021-2024 Land Rover Range Rover Velar and Land Rover Discovery, 2020-2023 Land Rover Range Rover Evoque, 2019-2024 Land Rover Range Rover Sport, 2020-2024 Land Rover Range Rover, 2020 Land Rover Discovery Sport, 2020-2024 Land Rover Defender, 2021-2024 Jaguar F-Pace, and 2021-2022 Jaguar E-Pace mild-hybrid electric vehicles (MHEVs). Insufficient electrical load balancing during times of high demand can lead to a current overload condition and malfunction of the DCDC converter. A failure of the DC-DC converter will result in a loss of 12-Volt system charging and can lead to complete loss of drive power and exterior lighting.
Consequence: A loss of drive power increases the risk of a crash.

Source: classified from NHTSA complaint and recall data. "Battery-related" includes high-voltage propulsion battery, charging system, hybrid drivetrain, electric propulsion, regenerative braking, 12V auxiliary battery, and thermal-event complaints. Other complaints (suspension, steering, brakes, infotainment) appear in the engine and vehicle-level sections. Rates are absolute counts, not normalized per-VIN — high-volume models naturally produce more raw complaints than low-volume ones. Self-reported death and injury counts are capped per complaint to limit form abuse.
