2009 LAND ROVER RANGE ROVER SPORT

Typical onset: 60,000-100,000 mi

Symptoms: Excessive oil consumption (1qt per 500-1000 miles), Blue smoke on cold start, Misfires and rough idle, Loss of compression, Metallic knocking noise

Fix: The supercharged 5.0L AJ-V8 suffers from piston-to-bore contact causing cylinder wall scoring. Requires complete engine rebuild or replacement with updated pistons and cylinder liner work. 40-60 hours labor for rebuild, 25-35 hours for used/reman engine swap.

Estimated cost: $12,000-22,000

Typical onset: 80,000-120,000 mi

Symptoms: Coolant loss with no visible leaks, White smoke from exhaust, Overheating, Milky oil, Rough running when cold

Fix: Both head gaskets fail, often secondary to overheating from cooling system issues. Requires both heads removed, decked if warped, new gaskets, timing components, and coolant system flush. 18-24 hours labor if heads are serviceable.

Estimated cost: $4,500-7,500

Typical onset: 70,000-110,000 mi

Symptoms: Transmission slipping or harsh shifts, Coolant in transmission fluid (strawberry milkshake), Transmission overheating warnings, Coolant loss, Transmission failure

Fix: The internal transmission oil cooler in the radiator fails, allowing coolant and ATF to mix. Requires radiator replacement, transmission flush or rebuild (if contamination caused damage), and all cooler lines flushed. 8-12 hours if trans survives, add 25-35 hours if trans needs rebuild.

Estimated cost: $2,500-4,000 (cooler only) or $7,000-12,000 (with trans rebuild)

Typical onset: 60,000-90,000 mi

Symptoms: Clunking when shifting into gear, Excessive vibration at idle, Harsh engagement into drive or reverse, Visible sagging of transmission

Fix: The main transmission mount fatigues and tears from the weight and torque of the supercharged engine. Requires removing crossmember and supporting transmission. 2-3 hours labor.

Estimated cost: $400-700

Typical onset: 70,000-110,000 mi

Symptoms: Supercharger whine or grinding noise, Reduced power, Check engine light with supercharger codes, Coolant leaks from front of engine

Fix: The dedicated electric coolant pump for the supercharger intercooler fails, causing reduced boost and potential supercharger damage from heat. Pump is mounted low on the engine. 3-4 hours labor.

Estimated cost: $800-1,400

Typical onset: 80,000-130,000 mi

Symptoms: Suspension warning light, Vehicle sagging on one corner or entirely, Compressor running constantly, Hissing from suspension, Inability to raise/lower suspension

Fix: Air suspension compressor burns out from overwork due to line leaks, or lines themselves crack at fittings. Compressor replacement is 3-4 hours, individual air spring or line replacement is 2-3 hours per corner.

Estimated cost: $1,200-2,000 (compressor) or $600-1,200 (per corner)

Typical onset: 100,000-140,000 mi

Symptoms: Rattling noise on cold start for 2-3 seconds, Check engine light with cam/crank correlation codes, Rough running, Loss of power

Fix: Primary and secondary timing chain tensioners weaken, guides wear. If caught early (just noise), preventive replacement is 12-16 hours. If chains jump timing, add valve damage inspection and potential head work.

Estimated cost: $3,000-5,000 (preventive) or $6,000-10,000 (with valve damage)

Typical onset: 90,000-130,000 mi

Symptoms: Hard starting, especially when hot, Rough idle and misfires, Loss of power under load, Check engine light with fuel trim codes

Fix: High-pressure fuel pump on the engine fails or fuel filter clogs from contamination. Filter should be changed every 30k but is often neglected. Pump replacement requires special tools and fuel system depressurization. 4-6 hours labor for pump.

Estimated cost: $1,200-2,200
