A recall of 23,677 Jaguar and Land Rover vehicles due to a failure of the DC-DC converter that can result in a loss of drive power.
Jaguar Land Rover North America, LLC (Land Rover) is recalling certain 2019-2024 Land Rover Range Rover Sport, 2020-2024 Land Rover Range Rover Evoque, Land Rover Range Rover, Land Rover Discovery Sport, Land Rover Defender, 2021-2024 Land Rover Range Rover Velar, Jaguar E-Pace, F-Pace, and Land Rover Discovery vehicles. The DC-DC converter may malfunction due to an electrical overload that can occur during high power demand. Additionally, a software error can cause the DC-DC converter to stop functioning at vehicle start-up under certain circumstances. Failure of the DC-DC converter will result in the loss of 12-Volt system charging and can lead to complete loss of drive power and exterior lighting.
Affected VINs should be searchable now at the NHTSA website.

The basis of the recall population of vehicles was determined through a combination of field data analysis and AI modelling to be Mild Hybrid Electric Vehicles (MHEVs) up to the end of 2024 Model Year, excluding those vehicles which have an earlier specification of DCDC converter and are included in recalls D126 or H575.
Description of defect or noncompliance:
A concern has been identified on Jaguar and Land Rover Mild Hybrid Electric Vehicles (MHEVs) where insufficient electrical load balancing during times of high demand can lead to a current overload condition and malfunction of the DCDC converter. Additionally, a software bug had been introduced which could cause the DCDC converter to stop functioning at vehicle start-up under certain circumstances.
Description of the safety risk, including crash, fire, death, injury:
A failure of the DCDC converter will result in a loss of 12V system charging, and a “Stop Safely Electrical Fault Detected” red warning. Should the customer ignore this warning and continue to drive, additional warnings may appear. Continuation of the journey will result in the vehicle losing motive power and coasting to a stop after a period of time, and eventually losing exterior lighting. A loss of motive power, or of vehicle lighting, will increase the risk of a crash.
Description of the cause:
None stated.
Identification of any warning that can occur:
Within 10 seconds of the failure, a red warning message saying “Stop Safely Electrical Fault Detected” will be displayed. Progressively as the 12V system loses charge, warnings including but not limited to Lane Keep Assistance being disabled, Suspension Fault, Stability Control Fault may be shown. Should the vehicle continue to be driven, the vehicle will shift into Neutral with a Gearbox fault shown. The engine will continue to run for a period of time, and exterior lighting will remain available after the center screen and air conditioning switches off. Eventually, the engine will shut down and, some time later, the battery will lose sufficient power to sustain exterior lighting.
Chronology
Following the decision to recall certain vehicles due to failure of the (phase 1) DCDC converter under JLR campaigns D126 & H575 (NHTSA reference 26V-248) in April 2026, JLR’s Product Safety and Compliance Committee (PSCC) has continued to monitor and progress the engineering investigation into the matter.
Through May, June and into July 2026, the PSCC heard that hardware-level stress testing was carried out on production DCDC converters to induce the failure and this work demonstrated that there was no evidence of later DCDC converters being routinely susceptible to the same failure mode that had previously been concluded to be the root cause of the failures under D126 & H575.
On 14 July 2026, the investigation task force reported to the PSCC that the workstream had shifted its primary focus to reviewing software content and changes after being unable to consistently induce hardware failures in DCDC converters. The investigation continued with rig-based physical experimentation whilst in parallel deploying a dedicated workforce to conduct a forensic review of every line of software code within the vehicles and analyse for individual changes or combinations of changes which could have had an impact on the performance of the DCDC converter.
Through the remainder of July and August 2026, the forensic software analysis continued, and in parallel an AI model was developed with a view to predicting future failures. The status of the investigation was regularly reviewed with the PSCC.
On 08 September 2026, the PSCC heard that the AI model had been successfully trained on a small, well-known population of vehicles and confirmed to be effective on a larger scale. It was reported that vehicles built with phase 2 DCDC converters up to the end of 24 Model Year are predicted to exhibit similar failures as those already recalled under D126 & H575. The PSCC was additionally informed that a software bug had been discovered on certain phase 2 vehicles which could theoretically result in the DCDC converter going offline at start-up with the same customer symptom of loss of 12V charging. It was noted that the real-world likelihood of this was not fully confirmed. The matter was referred to the PSCC Decision Forum.
On 10 September 2026, JLR’s PSCC Decision Forum reviewed the status of the investigation as well as the most recent AI-driven data analysis, which shows an elevated risk of failure for certain vehicles up to and including 24 Model Year, and requested that a safety recall be launched on the affected vehicles in the previously recalled markets.
JLR has received 393 claims and field reports in the US between April 2024 and September 2026.
There have been no reported accidents, injuries or fires in the US as a result of this concern.
Remedy
Description of Remedy
Remedy Type: Repair, Software
Description of remedy program:
Vehicles will have their software updated to ensure adequate load-balancing at times of high demand, as well as correcting the start-up stability bug. In addition, the software will introduce a protective “limp-home” mode which will provide a warning followed by a power derate in the event of the DCDC converter going offline for any reason.
There will be no charge for this remedy.
How remedy component differs from recalled component:
The remedy includes a new central software strategy to ensure adequate load balancing across the vehicle systems at times of high demand.
Description of recall schedule:
Notifications to dealers will occur on October 1, 2026. Distribution of owner notification letters will occur on or before November 13, 2026.
