The 2019 Range Rover with the 5.0L supercharged V8 is a luxury SUV plagued by catastrophic engine failures and transmission cooling issues that can bankrupt owners outside warranty. When they run, they're magnificent; the problem is keeping them running past 60,000 miles without a five-figure repair bill.
Catastrophic Engine Failure - Cylinder Liner/Piston Cracking
Common · high severityTypical onset: 40,000-80,000 mi
Symptoms: Metallic knocking from engine bay, especially on cold starts, White smoke from exhaust indicating coolant consumption, Sudden loss of coolant with no visible external leaks, Check engine light with misfire codes (P0300 series), Metal shavings in oil during changes
Fix: Complete engine rebuild or short block replacement required. Cylinder liners crack and allow coolant into combustion chambers, destroying pistons, rings, and bearings. This is a design flaw in the AJ-V8 Gen III engine. Expect 40-60 hours labor for short block swap, more for full rebuild. Many owners opt for remanufactured long blocks.
Estimated cost: $15,000-25,000
Transmission Oil Cooler Failure and Fluid Contamination
Common · high severityTypical onset: 50,000-90,000 mi
Symptoms: Transmission slipping or harsh shifts, especially when cold, Milky appearance to transmission fluid (coolant mixing), Transmission overheating warnings on dashboard, Rough or delayed engagement into gear, Engine coolant level dropping without visible leaks
Fix: Oil cooler internal seal fails, allowing coolant and ATF to mix. Requires cooler replacement, complete transmission fluid flush (multiple cycles), and often transmission filter/pan service. If not caught early, contaminated fluid destroys transmission clutch packs requiring full rebuild or replacement. 6-8 hours labor for cooler and thorough flush; add 25-35 hours if transmission is damaged.
Estimated cost: $1,800-3,500 (cooler only), $8,000-12,000 (if transmission damaged)
Timing Chain Tensioner and Guide Wear
Occasional · high severityTypical onset: 60,000-100,000 mi
Symptoms: Rattling noise from front of engine on startup that disappears after few seconds, Check engine light with cam/crank correlation codes (P0016, P0017), Rough idle or misfires, Metal debris in oil during changes, In severe cases, complete failure to start
Fix: Plastic-backed timing chain guides deteriorate and tensioners lose pressure. Requires removal of supercharger, front engine accessories, and timing cover. All chains, guides, tensioners, and gears should be replaced as assembly. 18-24 hours labor. Critical to address early—if chain jumps timing, valve-to-piston contact causes complete engine destruction.
Estimated cost: $5,000-8,000
Supercharger Coupler and Bearing Failure
Occasional · medium severityTypical onset: 70,000-120,000 mi
Symptoms: High-pitched whining or squealing from engine bay under acceleration, Loss of power and boost pressure, Check engine light with underboost codes (P0299), Rough rubber pieces found in intake system, Belt squealing that doesn't resolve with tensioner adjustment
Fix: The rubber coupler between supercharger and drive pulley degrades, or front bearings seize. Requires supercharger removal and rebuild or replacement. Coupler alone is 8-10 hours; bearing replacement requires supercharger rebuild adding another 6-8 hours. Many shops recommend full supercharger rebuild at this point given labor already invested.
Estimated cost: $2,500-4,000 (coupler), $4,500-7,000 (full rebuild)
Air Suspension Compressor and Strut Failures
Common · medium severityTypical onset: 50,000-90,000 mi
Symptoms: Vehicle sitting low, especially after sitting overnight, Suspension fault warning on dashboard, Compressor running constantly (audible from rear), Uneven ride height side-to-side, Harsh ride quality, loss of adaptive damping
Fix: Air struts develop leaks in bellows or valve blocks; compressor wears from overwork. Each strut is 2-3 hours; compressor is 3-4 hours. Front struts more prone to failure than rears. Compressor relay also fails frequently (common click-click-click under driver seat). Budget for multiple struts if one has failed—others typically follow within 10,000 miles.
Estimated cost: $1,200-1,800 per strut, $1,500-2,200 (compressor)
Fuel System Low Pressure Pump and Filter Clogging
Occasional · medium severityTypical onset: 60,000-100,000 mi
Symptoms: Hard starting, especially after sitting, Loss of power under acceleration, Engine stumbling or hesitation at highway speeds, Check engine light with fuel pressure codes (P0087, P0088), Engine stalling at idle after driving
Fix: In-tank low pressure pump fails or inline fuel filter clogs (despite being advertised as lifetime). Filter is buried under vehicle near tank, requires dropping exhaust and shields. Pump requires tank drop. 4-6 hours for filter, 8-10 hours for in-tank pump. Land Rover claims filter is non-serviceable but it absolutely needs changing. Use only premium fuel—these engines are intolerant of fuel quality issues.
Estimated cost: $800-1,200 (filter), $1,800-2,800 (pump)
Only buy if you have deep pockets or comprehensive warranty coverage—these are $15k+ engine failures waiting to happen, typically before 80,000 miles, and repair costs often exceed remaining vehicle value.
