Land Rover Range Rover P400
The 3.0L Ingenium straight-six petrol with 48V MHEV is the most reliable modern JLR engine. Note oil filter housing recall N908. Turbocharger and cooling system benefit from regular oil changes and adequate cool-down time after spirited driving.
Range Rover L460 P400: the premium flagship
In the new Range Rover L460 the inline-six petrol reaches its zenith. Silent at cruising speed, with direct thrust on demand. The driving feel is so composed that one barely misses the eight cylinders of the past.
Engine Weaknesses 6
Incorrect plastic specification for the Ingenium I6 3.0L petrol oil filter housing. The housing can crack and spray engine oil onto hot components. Fire risk. Recall N908.
Symptoms: Visible oil leak, oil puddles, oil warning light, in severe cases smoke or fire
The PT306 inline-six shows timing chain wear with rattling on cold start. Although more robust than the 2.0L four-cylinder, wear and tensioner issues are documented at higher mileages.
Symptoms: Metallic rattling on cold start, rough idle, engine warning light with camshaft correlation errors
PT306 turbochargers develop bearing wear and oil blow-by particularly with insufficient oil change intervals. Allow cool-down time after spirited driving.
Symptoms: Whistling or howling noise, smoke from exhaust, power loss, elevated oil consumption
The PT306 water pump and thermostat are known wear items. Failure leads either to persistent undercooling or dangerous overheating.
Symptoms: Temperature fluctuations, coolant loss, steam from bonnet, overheating warning
The turbocharged PT306 inline-six shows elevated oil consumption at higher mileages, especially under hard use. Causes: turbocharger shaft seal wear and short-trip degradation.
Symptoms: Regular top-ups required, faint blue smoke under acceleration
On the 48V mild hybrid system, the DC-DC converter from 48V to 12V fails. Without a working converter the 12V battery is not charged — complete vehicle shutdown is possible.
Symptoms: Charging system fault warning, red battery symbol, infotainment shutdown
Vehicle Weaknesses 4
Even on the new generation, early L460s show compressor failures and height sensor faults. ABS modulator noises addressed via OTA update. Repairs are inherently expensive. Regular maintenance extends service life.
Pivi Pro freezes, restarts or loses connectivity. Proximity auto-lock sometimes fails. OTA updates arrive regularly but occasionally introduce new problems. Coolant level warnings and engine warning lights due to ECU errors are known.
Flush electric door handles make loud noises when locking and unlocking on all four doors. Proximity function fails, doors must be opened manually by pressing a button. Problem officially acknowledged by JLR Engineering.
Early production years show panel gap variation at tailgate and doors as well as wind noise from door seals that do not sit correctly. MY25 model with revised door mirrors shows significantly less wind noise.
