Land Rover LR4 maintenance: the schedule, the costs, the traps
A full-size 7-seat SUV with a gas powertrain. Below: the service intervals with real cost ranges, the repairs LR4 owners actually report, and when a fleet operator would sell. Same data Carlyle uses to score fleet buys.
Service schedule
What it needs, and what that runs
| Interval | Service | Typical cost |
|---|---|---|
| 10,000 mi / 12 mo | Synthetic oil & filter, inspection, tire rotation, top-offs | $200-$450 |
| 30,000 mi | Engine air filter, cabin air filter, brake fluid flush | $400-$800 |
| 60,000 mi | Spark plugs, coolant service, supercharger has no belt-replacement interval (chain-driven), driveline fluid inspection | $600-$1,300 |
| 90,000 mi | Coolant change, ZF 8-speed transmission service, transfer-case/diff fluids | $1,000-$2,200 |
Known repair windows
What LR4 owners actually run into
Mileage ranges where these repairs typically show up. Buying above a window is not automatically a pass - it just needs to be priced in.
Air suspension compressor & air springs
high severity70,000-130,000 mi · $1,200-$2,800
Classic LR4 weak point; compressor burns out and rubber air springs leak, dropping the vehicle.
3.0 SC V6 timing chain / tensioner & guides
high severity90,000-150,000 mi · $3,000-$6,000
AJ126 supercharged V6 known for timing-chain tensioner/guide wear; front-cover-off repair is labor-intensive.
Coolant crossover pipe / water pump
high severity60,000-120,000 mi · $1,000-$2,500
Plastic crossover pipe under the supercharger and water pump leak; overheating risk, intake removal needed.
Electronic parking brake module
medium severity60,000-120,000 mi · $600-$1,300
Well-documented EPB actuator/module failure locking or faulting the parking brake.
Supercharger nose bearing / secondary tensioners
medium severity90,000-160,000 mi · $1,500-$3,500
Supercharger whine/bearing wear and drive-belt tensioner issues at high mileage.
Operator notes
US-market Discovery 4; final model year 2016. Final years used the 3.0L supercharged V6 (AJ126, timing CHAIN); earlier LR4s used a 5.0L V8. Body-on-frame-ish integrated body, air suspension standard. OE interval ~16,000 mi / 12 mo; given age treat as 10,000 mi on synthetic plus age items.
When the smart money sells
On fleet math, a gas LR4 retires around 95,000 miles - but the exit window opens earlier here: Coolant crossover pipe / water pump risk window ($1,000-$2,500) opens ~60,000 mi. Carlyle's garage tracks this per car, against your actual odometer.
Cost ranges are typical US independent-shop estimates and vary by region and condition. Modeling, not mechanic advice - always confirm against your car's service records.
