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.

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.

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.

Cost to keep
What it costs to own, by how long you keep it
Scheduled servicing only, from a brand-new LR4 at 12,000 miles a year. Insurance, fuel, tires and depreciation are yours to add - this is the part the shop charges you for.
| You keep it | Odometer | Servicing | Per month |
|---|---|---|---|
| 1 year | 12,000 mi | $325 | $27 |
| 3 years | 36,000 mi | $1,575 | $44 |
| 5 years | 60,000 mi | $4,100 | $68 |
| 7 years | 84,000 mi | $4,750 | $57 |
| 10 years | 120,000 mi | $9,800 | $82 |
| 15 years | 180,000 mi | $15,500 | $86 |
Per-month can dip as the horizon lengthens - a major service lands in one year and then averages out across all the months after it. The left column is what you actually spend.
Beyond the schedule, the first big-ticket item this LR4 is known for is Coolant crossover pipe / water pump from about 60,000 miles ($1,000-$2,500). It is a range, not a certainty - but it is the number to have in your head at the dealership.
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
Keeping it yourself, there is no cutoff - the table above runs to fifteen years. On fleet math, where a car has to keep earning, 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.
