Jaguar Land Rover Mild-Hybrid Recall: Models and Remedy

Which models are included?

The U.S. campaign covers certain mild-hybrid electric vehicles, or MHEVs, in the following groups. Jaguar Land Rover’s campaign references are D126 and H575.

This is a potential recall population, not a count of vehicles that have failed or remain unrepaired. A model and year match does not establish that a particular vehicle is included; the powertrain and actual VIN matter.

Why a charging fault can become a loss of power

The current NHTSA description identifies insufficient electrical load balancing during high demand. That can cause current overload and a DC-DC converter malfunction. The resulting loss of 12-volt system charging can progress to loss of drive power and exterior lighting, increasing crash risk.

That is more consequential than an inconvenience with a single electrical accessory. The manufacturer’s filing describes multiple warnings and systems becoming unavailable as the 12-volt supply loses charge. It does not provide a safe distance that an owner can continue driving.

Take the red “Stop Safely” warning literally

Jaguar Land Rover’s original safety filing identifies a red “Stop Safely Electrical Fault Detected” message. It says ignoring that warning and continuing the journey can lead to the vehicle losing drive power, coasting to a stop and eventually losing exterior lighting.

Follow the instruction to stop safely rather than continuing to see whether more warnings appear. Contact the appropriate Jaguar or Land Rover retailer for instructions for the vehicle. The sequence described in the filing is an explanation of the hazard, not a countdown or permission to drive until another system shuts down.

What changed about the letters and remedy?

The April 17, 2026 filing said the corrective action was not yet defined and planned interim owner notification by June 12. NHTSA’s current record instead reports that interim letters were mailed June 17, 2026. A planned mailing date and a reported mailing date are different; neither proves that an individual owner received a letter.

The current record says dealers will update the central software free of charge. It also says additional letters will be sent once the final remedy is available. Because both statements remain in the record, owners should ask the retailer for the latest D126 or H575 instructions for their VIN rather than assume an update is already available for every vehicle. A software-remedy description also does not establish over-the-air delivery or replacement of every converter.

Check eligibility and completion separately

Use the actual VIN in the manufacturer’s Land Rover or Jaguar recall search. Ask the retailer to identify this campaign and its current repair status, especially if a previous visit included electrical repairs or a software update.

NHTSA’s VIN search reports unrepaired recalls and excludes recalls already repaired. For a used vehicle, request the repair order showing its VIN, campaign number and work performed. An interim notice, unrelated software update or ordinary service visit does not by itself document completion of D126 or H575.
