Free VIN check — was it assembled in the US?
Paste the 17-character VIN. This reads NHTSA PlantCountry. It is a data check, not tax advice, and it does not decide whether any loan is deductible.
Severity: HIGH Severity: HIGH (orange). Why: Jaguar Land Rover told NHTSA that failure of the DC-DC converter “will result in a loss of 12V system charging,” and that if the driver continues after the red warning, “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.” It states: “A loss of motive power, or of vehicle lighting, will increase the risk of a crash” (NHTSA campaign 26V599000). Loss of drive power and exterior lighting fall under HIGH; there is a red “Stop Safely Electrical Fault Detected” warning before motive power is lost, and NHTSA’s record does not set a do-not-drive or park-outside advisory.

| Warning to driver | Red message “Stop Safely Electrical Fault Detected” within about 10 seconds of the failure; further warnings (including gearbox fault / shift to Neutral) may follow if driving continues |
| Remedy | Dealers will update vehicle software free of charge (load balancing, start-up bug fix, and a protective limp-home mode). Interim owner letters expected November 13, 2026; more letters when the final remedy is available |

What happened
On September 17, 2026, Jaguar Land Rover North America, LLC notified NHTSA of safety recall 26V599 (campaign 26V599000, JLR recall E008). In its Part 573 Safety Recall Report, JLR says a concern was identified on certain 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.” Separately, “a software bug had been introduced which could cause the DCDC converter to stop functioning at vehicle start-up under certain circumstances.”
JLR describes the safety risk this way: a DC-DC converter failure “will result in a loss of 12V system charging, and a ‘Stop Safely Electrical Fault Detected’ red warning.” If the customer ignores that warning and continues to drive, “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.”
This campaign expands earlier NHTSA recall 26V248000 (JLR campaigns D126 and H575). JLR says the new population was identified with field data and AI modelling as MHEVs through the end of the 2024 model year that use a later (“phase 2”) DC-DC converter, excluding vehicles already covered by those earlier recalls.
JLR reports 393 U.S. claims and field reports between April 2024 and September 2026 related to this concern, and says there have been no reported accidents, injuries or fires in the U.S. as a result. Its Product Safety and Compliance Committee Decision Forum directed a safety recall on September 10, 2026.
