Jaguar Land Rover (JLR) has announced a significant safety recall affecting 170,169 hybrid vehicles in North America. The recall stems from a technical flaw that can cause a sudden and total loss of motive power while the vehicle is in motion, posing a serious risk to driver and passenger safety.
The Technical Root Cause
The issue centers on the DC-DC converter, a critical component that manages electrical power within the vehicle. Investigations revealed that a fault in the boost control software —specifically involving a microchip—can cause the converter to fail.
When this failure occurs, the vehicle undergoes a rapid and cascading electrical shutdown:
– Initial Warning: Within 10 seconds of the failure, the driver will see a “Stop Safely Electrical Fault Detected” message.
– System Failures: As the 12-volt system loses its charge, secondary safety systems—including lane-keep assistance, stability control, and suspension —may malfunction or display warnings.
– Total Shutdown: If the driver continues to operate the vehicle, it will automatically shift into neutral and coast to a stop. Eventually, the engine shuts down, the center infotainment screen and air conditioning turn off, and even the exterior lights cease to function.
This sequence of events is particularly dangerous if it occurs at high speeds or in low-visibility conditions, as the driver loses both propulsion and essential lighting.
Affected Models
The recall encompasses a wide range of luxury SUVs and electric vehicles produced between 2019 and 2024. Affected models include:
- Land Rover:
- Range Rover Velar (2021–2024)
- Range Rover Evoque (2020–2023)
- Range Rover Sport (2019–2024)
- Range Rover (2020–2024)
- Discovery Sport (2020)
- Discovery (2021–2024)
- Defender (2021–2024)
- Jaguar:
- I-Pace (2021–2024)
- E-Pace (2021–2022)
A Disputed Safety Timeline
The path to this recall highlights a significant friction point between the automaker and federal regulators.
JLR first identified the potential issue in September 2024. At that time, the company initially categorized the problem as a matter of customer satisfaction rather than a critical safety defect, noting that the symptoms progressed gradually. However, after receiving further reports in 2025, the National Highway Traffic Safety Administration (NHTSA) intervened.
The NHTSA clarified its stance, asserting that the loss of power and lighting constitutes a safety-related defect. Following this directive, JLR moved to issue the formal recall. Data shows that between July 2019 and April 2026, JLR received 5,952 reports regarding DC-DC converter replacements. While no accidents, injuries, or fires have been reported to date, the potential for a collision remains high.
Current Status and Next Steps
As of now, JLR has not yet developed a permanent remedy for the software fault. The company is currently in the engineering phase of developing a fix and has promised to provide updates regarding the repair timeline at a later date.
Summary: JLR is recalling over 170,000 vehicles due to a software flaw that can trigger a total loss of power and lighting. While no injuries have been reported, the company is working on a technical fix following pressure from federal safety regulators.
