Common Failure
High-voltage battery degradation and charging system faults are commonly reported, alongside the 2.0L combustion engine's susceptibility to timing chain stretch and direct injector coking. Typical failure mileage ranges from 60,000 to 100,000 miles.
The AJ200P plug-in hybrid powertrain dominating the Range Rover Sport P400e offers excellent efficiency, but its complex integration of combustion and electric systems introduces specific failure points. Rebuilt AJ200P engines through EnginesMarket include upgraded components addressing these original failure points, plus a minimum 12-month unlimited-mileage warranty.
Why the Range Rover Sport P400e AJ200P Requires Specialist Attention
Affected Vehicles
Range Rover Sport P400e (AJ200P, 2017-2022)
Typical Failure Mileage
60,000-100,000 miles
Root Cause
The 13.1kWh battery pack and AC-DC converter can develop faults over time, leading to reduced electric range or failure to charge. This forces the 2.0L petrol engine to work harder and more frequently, exposing its inherent susceptibility to timing chain stretch and injector coking.

Vehicle Value Check
Vehicle Value Check
Modern Range Rover Sport L494 P400e values typically range from £18,000 to £35,000+ depending on specification, mileage, and service history [THIRD-PARTY]. Because the vehicle worth is well above £15,000, a £4,500-£7,500 rebuilt engine replacement cost is typically small relative to the vehicle value ( Safe). Replacing the engine preserves the vehicle's usability, hybrid efficiency, and strong market value.
Our Recommendation
Our Recommendation
If your Range Rover Sport P400e is only showing reduced electric range or minor charging faults but the 2.0L combustion engine runs smoothly, a specialist high-voltage system diagnostic and repair is the most cost-effective route. However, if the combustion engine has developed timing chain rattle or suffered wear from constant use due to a depleted battery, a full rebuilt unit is the only reliable long-term solution.

Question 2What are the signs of engine or hybrid system failure in a Range Rover Sport P400e-
The AJ200P powertrain can exhibit both electrical and mechanical warning signs. Watch for early indicators before catastrophic failure.
- Significantly reduced electric-only range or failure to charge via the AC port.
- Rough running or excessive vibration when the battery is depleted and the 2.0L engine is solely responsible for propulsion.
- A distinct metallic rattling noise from the engine bay on cold starts, indicating timing chain stretch.
Question 3Is it worth replacing the engine in a Range Rover Sport P400e-

- A £4,500-£7,500 rebuilt engine preserves the vehicle's drivability, hybrid efficiency, and market appeal.
Question 4How long does a Range Rover Sport P400e engine replacement take-
Because the AJ200P is a complex plug-in hybrid powertrain, a specialist workshop requires hybrid-trained technicians and specific JLR diagnostic tools.
- Engine removal, high-voltage system isolation, and refitting usually takes 12 to 16 hours of labour.
- Total workshop turnaround is typically 3 to 5 working days, including ECU coding and hybrid system calibration.
