Is the Land Rover Range Rover Sport P440e reliable?

The P440e combines the proven AJ20P6 3.0-litre Ingenium petrol engine with a 105kW electric motor. The combustion engine is well-developed and reliable, with ignition coils as the main wear item. The hybrid system adds complexity, but early owner reports indicate strong reliability. Battery health is the long-term question mark — all lithium-ion batteries degrade over time.

What are the common problems with the Range Rover Sport P440e?

PHEV battery degradation (reduced electric range, £8,000–£12,000 replacement), ignition coil failure on the combustion engine (misfire, rough idle, £350–£600 repair), and hybrid system software issues (drive mode malfunctions, warning lights, £150–£500 software update).

Is it worth replacing a Range Rover Sport P440e powertrain, or should I scrap the car?

Range Rover Sport P440e values range from £60,000–£120,000 depending on year, condition and mileage. A £6,500–£10,000 reconditioned powertrain represents 5–15% of vehicle value — well within our 60% Land Rover scrap threshold. For most examples, replacement is financially viable. Battery replacement at £8,000–£12,000 is a separate consideration.

How do I find my Land Rover Range Rover Sport P440e engine code?

The P440e uses the AJ20P6 engine code — JLR's 3.0-litre Ingenium inline-six — combined with a 105kW electric motor. This is the same engine as the P400 but with additional hybrid hardware. The total system output is 440PS. The code is stamped on the engine block; your VIN and vehicle documentation will also confirm the specification.

Can I repair the battery degradation issue, or does it need replacement?

In many cases, individual battery modules can be replaced (£2,000–£4,000 per module) rather than the entire pack (£8,000–£12,000). A Land Rover specialist can perform a battery health check to determine which cells have degraded. At the first sign of significant range reduction, book a health check. Regular AC charging (rather than rapid DC charging) and avoiding deep discharges help preserve battery life.

Buying This Range Rover Sport P440e? Check These First

Buy If

Full Land Rover service history with documented battery health checks
Recent software updates applied (PCM, BMS, TCU)
Low-mileage with documented charging history (AC charging preferred)
Still under the 3-year/80,000-mile battery warranty (check transferability)

Avoid If

Significant reduction in electric-only range (battery degradation warning)
Any hybrid system warnings or drive mode malfunctions without a documented fix
Poor charging history (frequent rapid charging or deep discharges)
Missing service history — the PHEV system is complex and unforgiving

Closing Verdict

The P440e is a landmark powertrain — combining the refined 3.0-litre Ingenium petrol engine with a powerful electric motor for 440PS of seamless performance. The combustion engine is the same well-developed unit as the P400, while the hybrid system adds electric range and lower running costs. Battery health is the long-term question mark — buy on documented history, charge it properly, and this is a genuinely compelling plug-in hybrid.

Charging History — Has the vehicle been charged correctly? Frequent rapid charging can degrade batteries

Cold Start — Listen for any rattle on startup (timing chain stretch warning)

Service History — Must show hybrid system checks; 12,000 mile oil changes are essential

Misfire Check — Any hesitation, rough idle, or engine warning light? (coil failure)

Hybrid System — Check all drive modes work; any warning lights or messages?

Engine Warning Light — Have codes been read? Coil and hybrid system codes are common

MOT History — Check for emissions-related failures
