If Your Range Rover Is in the 2026 DCDC‑Converter Recall: Symptoms, Immediate Steps, and What to Expect

What this update covers

This post summarizes the two recent NHTSA recall filings that affect Range Rover models in 2026, explains the electrical‑system recall’s specific symptoms, and gives a practical, safety‑first checklist for owners who may be affected or who see an in‑vehicle warning. The guidance below is based on the official recall filings and supporting reporting; do not rely on unofficial fixes.

Recalls to know right now

There are two recent NHTSA safety recall filings that Range Rover owners should be aware of:

• NHTSA 26V248 / JLR campaign D126 H575: a large recall covering 170,169 mild‑hybrid (MHEV) Jaguar and Land Rover vehicles built before a revised DC‑DC converter specification; submission date Apr 17, 2026. (NHTSA 26V248)
• NHTSA 26V097 / JLR campaign D095: a limited recall affecting 178 Range Rover and Range Rover Sport vehicles for a panoramic roof side finisher adhesion issue; submission date Feb 23, 2026. The remedy for this small campaign is defined and dealers will re‑attach the finisher. (NHTSA 26V097)

Why the big (26V248) recall matters to MHEV Range Rover owners

The 26V248 filing describes a potential internal failure in the DC‑DC converter caused by a boost‑control microchip fault (supplier parts from LG Innotek and Yazaki are named in the filing). If the converter fails, an affected vehicle can lose 12‑volt charging and trigger a rapid sequence of faults that may include a red dashboard message and progressive loss of vehicle systems. (NHTSA 26V248)

Reported symptoms

• A red message stating "Stop Safely Electrical Fault Detected" can appear within roughly 10 seconds of failure.
• Subsequent warnings may include loss of 12V charging, stability and suspension alerts, gearbox faults and, in some cases, the vehicle shifting to neutral or losing motive power and exterior lighting.
• JLR documented 5,952 U.S. field reports/claims related to DC‑DC converter replacements between July 2019 and April 2026 in the filing; no U.S. accidents, injuries, or fires were reported in that filing. (NHTSA 26V248)

Immediate safety checklist if you see the electrical fault message

Follow a safety‑first approach. The steps below are practical actions based on the recall advisory and common roadside safety practice:

1. Stop safely as soon as you can: when the red "Stop Safely Electrical Fault Detected" appears, pull over promptly to a safe location and park off the road.
2. Turn on hazards and make the vehicle visible: ensure hazard lights are activated and you and passengers are clear of traffic.
3. Do not continue driving if the vehicle is losing power or lights: the NHTSA filing includes a consumer advisory that cautions owners about driving or parking outside when the fault occurs; follow official guidance and avoid driving the vehicle if systems are failing. (NHTSA 26V248)
4. Contact roadside assistance or your dealer: arrange towing to a dealer rather than driving the vehicle if major faults are present; dealers had been scheduled to receive campaign notifications starting May 1, 2026. (NHTSA 26V248)
5. Document the event: photograph the dashboard message, exterior lighting status, odometer reading, and any other visible warnings. Keep these records for the dealer and for any warranty/field‑report follow up.

What owners should do now, even before a warning appears

• Check whether your vehicle falls in the affected production window: the official NHTSA recall report lists model‑by‑model production dates and unit counts; owners should compare their vehicle’s VIN/production date to the filing. (NHTSA 26V248)
• Watch for the owner notification: JLR planned an interim owner notification on or before Jun 12, 2026 and said VIN lookup/remedy letters would follow — the remedy itself was under development at the time of the filing. (NHTSA 26V248)
• If you own a Solihull‑built 2023–2026 Range Rover or Range Rover Sport: check your vehicle against campaign 26V097 too; that campaign affects a small population and the remedy (re‑attaching the panoramic roof side finisher) is already defined. (NHTSA 26V097)

What to expect from the dealer and JLR

For 26V248, JLR’s filing indicates a remedy was still being developed as of the April 17, 2026 submission; dealers were scheduled to receive campaign notices beginning May 1, 2026 and owners an interim notice on or before June 12, 2026. Once the recall remedy is finalized, dealers will be instructed on parts and repair procedures and VIN lookup tools should be published. (NHTSA 26V248)

Further reading and official documents

If you’re unsure whether your Range Rover is affected, keep the documentation above saved and contact your dealer once VIN lookup tools are published; follow official instructions from JLR and NHTSA rather than third‑party repair suggestions. Safety first: if the red electrical fault warning appears, stop safely and contact assistance.
