2003-2012 Land Rover Range Rover 3rd Gen Maintenance and Cost
Maintenance on the L322 Range Rover is expensive because it is a premium SUV - and it's not particularly reliable. It's a car you buy for its all-conquering off-road talent, luxurious interior, and comfort, not for problem-free service. Since they are now quite old, even considering one with a patchy maintenance history is a big no-no. Carefully peruse the service history and try to find one that has had its oil changes every 7,500 miles at least and not at the prescribed 15,000-mile intervals according to the book. Models serviced by the book at 15,000-mile intervals can be reliable if they were lightly used for long-distance cruising and not for towing or off-road, but you'll have to examine the car carefully to see how it's been treated and maintained.
The cabin filter must be changed every 15,000 miles and the transfer case's oil every 30,000 miles. The 30,000-mile service typically costs around $1,000 at Land Rover and over $600 elsewhere on 2003-2005 cars, but $660 and $400 respectively on 2006-2009 4.4-liters. The cooling system should be flushed and refilled every 60,000 miles, and this service should amount to around $1,600 independently or $2,100 at Land Rover on 2003-2005 cars. At 90,000 miles, the brake fluid and differential oil must be changed on the 2003-2005 models, but we would reduce that to between 60,000-75,000 miles for the differential service, seeing how much trouble these parts caused on the L322. Not all services can be compared, since the service items and mileages changed with almost every engine, but the AJ-V8 4.4-liter engines are the cheapest to run; the 2003-2005 BMW engine is finicky and expensive to run, and the 2010+ 5.0-liters are less reliable and require more frequent maintenance.
On the AJ-V8 engines used from 2006, the cooling system's refill is every 30,000 miles, which is sensible, and the brake-fluid and differential-oil changes are every 75,000 miles; on 5.0-liter cars, the brake-fluid change is every 60,000 miles. It is a little bit worrying that you have to replace the brake hoses on the 4.2-liter supercharged models every 90,000 miles and on 5.0-liter cars, every 75,000 miles, as this is quite unusual and may indicate a potential weakness. That being said, there were never actually any 2006-2013 Land Rover Range Rover Supercharged recalls to deal with potential brake problems. Transmission fluid cannot be replaced too frequently, and we regard 60,000-mile intervals as the absolute maximum for a big and heavy SUV like the Range Rover, especially if you're going to tow with it.
