JLR mild-hybrid power-loss recall: what UK owners must check

JLR mild hybrid recall: which 2019-2024 MHEV Range Rover, Defender and Jaguar models are affected and how UK owners check their VIN now.

The JLR mild hybrid recall is the safety story premium owners keep asking us about, after Jaguar Land Rover confirmed a DC-DC converter fault on its 48V MHEV models that can cut drive power and exterior lighting while you are moving. The action began in the United States, where regulators logged it against roughly 170,000 vehicles, but the same 2019 to 2024 mild hybrid models were sold here, so UK owners should check their VIN now and watch for the warning.

What the JLR mild hybrid recall actually covers

The defect sits in the DC-DC converter, the unit that charges the 12V electrical system on a mild hybrid the way an alternator does on a conventional car. An internal fault in the converter’s boost-control microchip can make it fail. According to Carscoops, reporting on the US filing, three converter part numbers from LG Innotek and Yazaki are involved. JLR first reviewed the issue in September 2024 and judged it not a safety risk; further reports and testing led a JLR task force to reclassify it as a safety defect in April 2026, after a regulator review.

Which UK models and years are affected

The US action names nine model lines, all built to mild hybrid (MHEV) specification across roughly 2019 to 2024: on the Land Rover side, the Range Rover, Range Rover Sport, Velar, Evoque, Discovery, Discovery Sport and Defender; on the Jaguar side, the F-Pace and E-Pace. Only the 48V mild hybrid versions are caught, not every car in those ranges, so a VIN check matters more than the badge on the boot. If you are weighing a used Range Rover Evoque L551 or a used Defender L663, confirm recall status before any deposit.

What happens when the converter fails

The failure is staged rather than instant, which is part of why it took a second look to land as a recall. Within about 10 seconds of the converter giving up, the driver sees a red “Stop Safely Electrical Fault Detected” message and the 12V system stops charging. Keep going and the warnings cascade: driver-assistance such as lane-keep assist drops out, suspension and stability-control faults appear, and eventually the car can shift into neutral, the engine can shut down and the exterior lights can fail. No crashes, fires or injuries were reported at the time of the filing, but losing lights and drive in traffic or after dark is plainly serious.

What real owners say (CDE data)

CDE reviewed owner discussion on PistonHeads and the Land Rover Owners’ Forum alongside Carscoops and WardsAuto coverage in June 2026, and cross-checked the UK recall position via gov.uk.

  • Most-raised worry: whether an affected car is safe to drive before a fix exists, given the staged power loss.
  • Most-raised gripe: no remedy yet, so owners expect an interim notice rather than an immediate booking.
  • Reliability signal: the US filing cites around 6,000 field reports, with no crashes, fires or injuries logged at the time, per Carscoops.

What UK owners should do right now

First, run a free check at gov.uk/check-vehicle-recall, the official DVSA-linked service, using your registration or your make, model and year. Second, treat any red “Stop Safely Electrical Fault Detected” message as a reason to stop somewhere safe. Third, expect paperwork in stages: interim owner letters tied to the US action were scheduled to mail from around 12 June 2026, with a second once a fix is ready, and any UK remedy under a manufacturer recall is free. A JLR retailer can confirm whether your VIN is in scope.

Is the car safe to drive, and what about resale?

On safety, stick to what JLR and the regulator have said: the fault gives staged warnings before power is lost, so act on the dashboard alert rather than ignore it. On resale, an open recall is not the disaster some sellers fear. It is logged against the VIN, the fix is free, and a completed recall is a tidy thing to show a buyer. The trap is buying privately from someone who has ignored the notice, so make the recall lookup part of your pre-purchase checks, alongside our notes on Range Rover insurance costs in 2026 and on Jaguar F-Pace X761 used reliability.

Where to check next

If you own or are buying one of these cars, work through these UK checks: confirm recall status at gov.uk/check-vehicle-recall by registration; review the MOT history on the same service; ask a JLR retailer to confirm the VIN is in scope and book the remedy when released; and on a used buy, run an HPI-style provenance check so an unactioned recall cannot slip through. For how these notices play out, see our Audi e-tron brake-servo recall coverage, and watch our latest car news.

Our take

Our view on the JLR mild hybrid recall is that it is serious but manageable, and the worst response is to do nothing. The fault is real, the model spread is wide, and JLR initially waving it through before a regulator review forced a rethink is exactly what this site exists to flag. But the staged warnings buy you a moment, the fix will be free, and a recall logged against a VIN is easy to track and clear. We would check our registration at gov.uk today, treat a “Stop Safely” alert as a hard stop, and on any used Velar, Evoque, Defender, Discovery or F-Pace we would make the recall lookup non-negotiable before a deposit. What flips us to worried is an alert ignored, or a seller who cannot show the recall has been actioned.

How do I check if my car is in the JLR mild hybrid recall?

Use the free official service at gov.uk/check-vehicle-recall, entering your registration or your make, model and year. It shows any outstanding safety recall on the vehicle. A JLR retailer can also confirm whether your specific VIN is in scope, the surest answer for a mild hybrid model.

Which JLR models are affected?

The mild hybrid (48V MHEV) Range Rover, Range Rover Sport, Velar, Evoque, Discovery, Discovery Sport and Defender, plus the Jaguar F-Pace and E-Pace, across roughly 2019 to 2024. Only mild hybrid variants are caught, not every car in those ranges, so a VIN check is the reliable way to know.

Is it safe to drive in the meantime?

The fault gives staged dashboard warnings before drive power is lost, starting with a red “Stop Safely Electrical Fault Detected” message. If that appears, stop somewhere safe and do not press on. Follow JLR’s official guidance and your owner letter, and book the remedy once a fix is released; recall repairs are free.

Will the recall fix cost me anything?

No. Under a manufacturer safety recall the inspection and any repair are free; the sticking point is timing, not cost, as no remedy was finalised at the time of the filing.
