The 2002 Range Rover with the 4.0L V8 (BMW M62-based engine) is mechanically ambitious but notorious for catastrophic engine failure due to cylinder liner slippage, plus transmission cooling and air suspension issues that define ownership experience.
Cylinder Liner Slippage / Engine Block Failure
Common · high severityTypical onset: 60,000-120,000 mi
Symptoms: Coolant loss with no external leaks, White smoke from exhaust on cold start, Overheating under load, Rough idle and misfires, Coolant in oil (milky dipstick), Loss of compression in one or more cylinders
Fix: The M62 V8 suffers from Nikasil-coated aluminum block liner failure where the thin liners slip down into the crankcase. Only real fix is complete engine replacement or short block swap with top-end rebuild. Expect 25-35 labor hours for complete engine R&R plus machine work if attempting liner repair (rarely successful long-term). Most shops recommend sourced replacement engine.
Estimated cost: $6,000-12,000
Head Gasket Failure (Secondary to Overheating)
Common · high severityTypical onset: 70,000-110,000 mi
Symptoms: Coolant loss, Overheating, Rough running, Steam from exhaust, Oil and coolant cross-contamination
Fix: Often occurs after chronic overheating from cooling system neglect or as precursor to liner issues. Both head gaskets require removal of intake manifolds, valley pan, and extensive ancillaries on this transverse-mount V8. 16-22 labor hours if heads don't need machining. Problem: by the time heads are off, you often discover the liner problem too.
Estimated cost: $3,500-5,500
Transmission Oil Cooler Line Failure
Common · high severityTypical onset: 80,000-140,000 mi
Symptoms: Transmission fluid leaking near radiator, Sudden transmission fluid loss, Harsh or slipping shifts, Pink coolant or milky transmission fluid (internal cooler failure), Transmission overheating warning
Fix: The external cooler lines rust through or the internal radiator-mounted cooler fails, allowing coolant and ATF to mix. External line replacement is 2-3 hours; internal cooler failure requires radiator replacement and complete transmission fluid flush (8-12 hours total to prevent valve body damage). If fluids mixed significantly, expect transmission rebuild within 5,000 miles.
Estimated cost: $400-1,200 (lines only) / $2,500-4,500 (with radiator and flush)
Air Suspension Compressor and Bag Failure
Common · medium severityTypical onset: 60,000-100,000 mi
Symptoms: Vehicle sagging at one corner or entire side, Suspension won't rise after startup, Compressor runs constantly, Warning light and 'suspension fault' message, Harsh ride quality
Fix: Air springs crack and leak, compressor overworks and burns out. Common to replace all four bags preventively when one fails (6-8 hours labor). Compressor replacement adds another 3-4 hours. Many owners convert to coil springs ($1,200-1,800 parts/labor) to eliminate the system permanently.
Estimated cost: $1,800-3,500 (full air system rebuild) / $1,200-1,800 (coil conversion)
Transmission Mounts Collapsing
Common · medium severityTypical onset: 70,000-120,000 mi
Symptoms: Clunk when shifting from Park to Drive, Excessive vibration at idle, Driveline shudder on acceleration, Visible transmission sag
Fix: The heavy ZF 4HP24 transmission destroys its rubber mounts, especially if engine mounts are also worn. Replacing transmission mount requires supporting transmission and is often done with engine mounts simultaneously. 4-6 hours labor for both engine and trans mounts.
Estimated cost: $800-1,400
WABCO ABS Modulator Valve Failure
Occasional · high severityTypical onset: 80,000-130,000 mi
Symptoms: ABS and traction control warning lights, Loss of ABS function, Spongy or hard brake pedal, Brake fluid leaking from modulator
Fix: The Wabco-D ABS modulator corrodes internally and fails. Requires complete unit replacement (dealer programming needed). 3-4 hours labor plus expensive modulator unit ($800-1,200 parts alone). No rebuild option; must replace with new or quality remanufactured unit.
Estimated cost: $1,500-2,200
Fuel Pump and Fuel Filter Housing Corrosion
Occasional · medium severityTypical onset: 90,000-150,000 mi
Symptoms: Hard starting especially when hot, Stalling after refueling, Rough running under load, Check engine light with lean codes, Fuel smell from rear of vehicle
Fix: In-tank fuel pump fails or fuel filter housing (under vehicle near tank) corrodes and leaks. Filter housing is plastic and cracks from road salt exposure. Pump replacement requires tank drop (4-5 hours); filter housing is 2-3 hours but often requires cutting rusted lines.
Estimated cost: $600-1,200
