A class-action lawsuit has been filed in the United States against Jaguar Land Rover over a hybrid system malfunction in Land Rover and Range Rover vehicles. The plaintiffs allege that the company knew about the defect for years but concealed it from buyers and failed to fix the issue even after announcing a large-scale recall, according to Autoblog.
The lawsuit covers crossovers and SUVs with mild hybrid systems (MHEV) produced from 2019 to 2024. According to the plaintiffs, the malfunction is caused by a defective DC/DC converter that powers the 12-volt system from a 48-volt battery. A failure could lead to electrical system malfunctions, loss of propulsion, and vehicle stalling.
In April 2026, JLR recalled more than 170,000 vehicles in the US due to this issue. However, according to the plaintiffs, the recall did not resolve the problem. Drivers were advised to stop immediately if a warning light appeared on the dashboard, while a permanent fix was still being developed.
Models affected by the lawsuit include the Range Rover, Range Rover Sport, Defender, Discovery, Discovery Sport, Range Rover Velar, and Range Rover Evoque, as well as some Jaguar models.
The court will now determine whether the manufacturer concealed information about the defect and violated warranty obligations to vehicle owners.
Previously, similar class-action lawsuits were filed against Toyota over an automatic transmission defect and against Honda over peeling white paint that impairs visibility.
