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. OFFICIAL REPORTED CONSEQUENCE A loss of drive power increases the risk of a crash. OFFICIAL REPORTED REMEDY Dealers will update the vehicle software, free of charge. Interim letters notifying owners of the safety risk are expected to be mailed November 13, 2026. Additional letters will be sent once the final remedy is available. Owners may contact Land Rover's customer service at 800-637-6837. Land Rover's number for this recall is E008. This recall expands previous NHTSA recall number 26V248. OWNER PREPARATION Keep existing warnings or observations for service. This guide does not ask you to probe wiring, disconnect a battery or open a high-voltage assembly. REMEDY TIMING IN THE DATED SOURCE The source describes a pending remedy or parts The dated official record describes development, future availability or a later remedy step. It does not establish today’s parts or appointment availability. Confirm the current remedy and any interim instructions with the manufacturer. Additional letters will be sent once the final remedy is available. Current availability for your VIN: unconfirmed. YOUR SERVICE QUESTIONS 1. Does the manufacturer confirm that campaign 26V599000 applies to this VIN, including the report’s equipment and production restrictions? A matching model and year is only a starting point. The official lookup or manufacturer must establish the individual vehicle’s status. Discussion status / answer: __________ 2. The source describes a pending remedy or parts. What is available now for this VIN, and which interim instructions still apply? The dated official record describes development, future availability or a later remedy step. It does not establish today’s parts or appointment availability. Confirm the current remedy and any interim instructions with the manufacturer. Discussion status / answer: __________ 3. Does the prescribed software remedy address both high-demand overload and the startup software condition described in E008? The official report describes two failure circumstances affecting the DC-DC converter. Ask the provider to explain the applicable remedy without testing either condition. Discussion status / answer: __________ 4. What transport and interim instructions apply if 12-Volt charging, exterior lighting or drive power has already been lost? Keep the existing warning and service history together. A charged 12-Volt battery does not establish that the campaign remedy is complete. Discussion status / answer: __________ 5. Which electrical component or software function is covered, and what interim charging, parking or use instructions does the manufacturer give? Compare the answer with the reported component: ELECTRICAL SYSTEM:PROPULSION SYSTEM:DC/DC CONVERTER. Discussion status / answer: __________ 6. Which module and software completion record demonstrate that the update for 26V599000 was applied? Ask the service provider how the campaign-specific software remedy is documented. A dashboard reset is not evidence of the specified update. Discussion status / answer: __________ 7. How does this campaign relate to 26V248000, and does work recorded under an earlier campaign satisfy the current remedy? Show any earlier work order. Related recall numbers can describe expanded or repeated work; ask the manufacturer to reconcile the records. Discussion status / answer: __________ 8. What dated document records the remedy performed under 26V599000, and what should I do if the reported concern remains? Keep campaign completion and unresolved symptoms as separate questions. A saved worksheet or booked appointment does not establish a repair. Discussion status / answer: __________ OFFICIAL LOOKUP DECISIONS Not checked or unavailable: eligibility remains unconfirmed; use the official lookup or manufacturer. Campaign listed as open: confirm current instructions, availability and remedy arrangements. Campaign not listed as open: reconcile repair history and lookup coverage with the manufacturer if needed. A zero-open result does not diagnose symptoms. Work order records completed recall work: keep the exact campaign and dated remedy record; report unresolved symptoms separately. YOUR RECORD Check date: __________ Official lookup result: __________ Service arrangement: __________ Existing observation: __________ Questions and work-order notes (no VIN or plate needed): __________ LOOKUP LIMITS A model/year match does not establish VIN eligibility. The official lookup may omit completed recalls, some recent campaigns or recalls outside its coverage. The listed defect does not prove the cause of a symptom on your vehicle.
