Range Rover L460 Engine Problems: Symptoms, Causes and What to Do

The Range Rover L460 engine problems reported so far mostly show up as misfires and rough running on the 3.0 six-cylinder petrol engines, oil leaks from specific components covered by recalls, and loss of 12-volt charging or drive power linked to the mild-hybrid DC-DC converter. Plug-in hybrids have their own battery warnings and recalls. Many of these faults have a JLR recall or technical bulletin behind them, and some are fixed with software rather than parts. The L460 is still a young car, so the first step is usually to check warranty and recall status before paying for anything. This guide is organised by what you notice.

L460 Engines in Brief

The fifth-generation Range Rover (L460) arrived in 2022 with modern six-cylinder and V8 engines, all electrified to some degree.

L460 Engine Problems by Symptom

Misfires, Rough Running and Warning Lights

Misfires on the 3.0 petrol (AJ20P6). JLR bulletin SSM000030 (March 2026) covers "combustion instability" on 2024-onwards Range Rover and Range Rover Sport models with the AJ20P6 mild-hybrid and plug-in hybrid petrol engines. Symptoms include the engine warning light, misfires (usually several cylinders at once), rough running, hesitation and reduced acceleration. The bulletin's procedure is to record data on a specified cold-start drive cycle and, if needed, update the engine, transmission and hybrid control software. It says not to replace components. It also recommends premium unleaded of at least 95 RON, with 98 RON as an alternative. If your P400 or PHEV misfires, ask a retailer whether this bulletin applies before anyone replaces coils or injectors.

Gearbox warning and no Drive or Reverse. It is not an engine fault, but owners often report it as one. Bulletin SSM76346 (June 2025) covers a gearbox warning and an inability to select D or R on 2024–2025 L460s with the V8 and the 3.0 petrol PHEV, with fault code P0850-94 stored. The root cause was still being investigated. The bulletin's interim instruction is to clear the code and not replace parts.

General warning lights. On any L460, a warning light needs a proper diagnostic scan. The car's many control modules mean that one fault can trigger several messages. Our engine diagnostics and repair service provides a written diagnosis before any repair begins.

Oil Leaks, Loss of Drive and Hybrid Warnings

Oil leaks covered by recalls. Several L460 recalls involve oil leaking in the engine bay:

• 23V044: a cam carrier oil gallery not fully drilled on some 2023 3.0 petrol engines, which could cause an external leak or oil entering the intake
• 23V222: a missing or misfitted turbo oil drain gasket on a 4.4 V8, which affected one vehicle
• 23V790: loose engine oil cooler hoses on some 2024 Range Rovers
• 24V450: an oil filter housing that can crack and leak oil on 2023–2024 Range Rovers among other models

Leaking oil near hot components is a fire risk, so a burning-oil smell or visible oil in the engine bay needs checking straight away. If a turbo is affected, our turbo replacement service identifies the cause before recommending any parts.

Loss of drive power or 12-volt charging (mild hybrids). NHTSA recalls 26V248 and 26V599 cover DC-DC converter faults on JLR mild hybrids, including some Range Rovers. They can cause loss of 12-volt charging and, in some cases, loss of drive power. Battery or charging warnings on these cars may not be an engine fault at all.

PHEV battery warnings and range. NHTSA recall 23V568 covered a small number of 2023 PHEVs whose high-voltage battery busbar bolts may not have reached the required clamp force, which risked arcing and fire. The fix was a battery pack replacement. JLR's interim advice was to stop safely if a red battery-fault warning appeared. Separately, JLR action D101 (May 2026) replaces two battery modules on some 2024–2025 Range Rover PHEVs because of weld quality that can reduce electric range. JLR classes D101 as non-safety. If your PHEV's electric range has dropped noticeably, ask a retailer whether D101 applies.

What to Do First

On a car this new, the order matters:

1. Check recall status by registration on the GOV.UK vehicle recall checker.
2. Check whether the manufacturer's warranty or an extended warranty still applies.
3. Get a proper diagnosis before any parts are replaced, because some faults are fixed with software.

FAQs

Range Rover L460 Engine FAQs

Is the L460 Range Rover engine reliable?
 The L460 is still a young model. The reported engine-related issues so far are mostly specific and covered by recalls or bulletins, such as oil leaks from particular parts, petrol misfires fixed by software and mild-hybrid converter faults. Check that all recall work has been done.

Why does my L460 3.0 petrol misfire?
 JLR bulletin SSM000030 covers combustion instability on 2024-onwards AJ20P6 petrol engines. The procedure involves data recording and software updates rather than new parts, and JLR recommends at least 95 RON fuel.

What does a DC-DC converter fault do?
 On mild hybrids it can stop the 12-volt battery charging and, in some cases, cause a loss of drive power. Recalls 26V248 and 26V599 cover this on some JLR models.

My PHEV's electric range has dropped. Is that a fault?
 It could be. JLR action D101 replaces battery modules on some 2024–2025 Range Rover PHEVs because of weld quality that can reduce range. Ask a retailer whether it applies to your car.

How do I check my L460 for recalls?
 Enter your registration on the GOV.UK vehicle recall checker, or ask a Land Rover retailer. Recall work is done free at authorised repairers.
