2022 LAND ROVER DEFENDER 90

Typical onset: 15,000-45,000 mi

Symptoms: metallic knocking on cold start, sudden loss of oil pressure, engine seizure, metal shavings in oil, check engine light with low oil pressure codes

Fix: Complete engine teardown reveals spun rod or main bearings, often requiring short block replacement or full rebuild. This is a catastrophic failure traced to inadequate oiling or bearing clearance issues in early production engines. 40-60 hours labor for short block swap, more if you're rebuilding long block in-house.

Estimated cost: $18,000-28,000

Typical onset: 20,000-50,000 mi

Symptoms: transmission fluid drips under vehicle center, burnt smell after highway driving, transmission temperature warnings, pink fluid on driveway, slipping between gears when hot

Fix: Factory cooler lines crack at crimp points or develop pinhole leaks from road debris and vibration. Requires dropping skid plates and replacing both hard and flex lines as an assembly — Land Rover revised the part twice already. 3-4 hours labor plus fluid flush.

Estimated cost: $800-1,400

Typical onset: 25,000-60,000 mi

Symptoms: clunk when shifting from Park to Drive, vibration at idle in gear, driveline shudder on acceleration, visible sagging or torn rubber on inspection

Fix: The main transmission mount tears prematurely, especially on vehicles used off-road or with aggressive driving. Rubber compound seems inadequate for the torque. Replace the mount and inspect transfer case mounts at same time. 2-3 hours labor.

Estimated cost: $500-900

Symptoms: hesitation on acceleration, limp mode activation, hard starting when cold, loss of power above 3000 RPM, multiple fuel system fault codes

Fix: Early diesel Defenders (if optioned) suffer from contaminated fuel filters much sooner than the 30k service interval — traced to either tank manufacturing debris or inadequate pre-delivery prep. Replace filter and check for tank contamination. If gas P300, this is rare but can happen from bad fuel. 1.5-2 hours labor.

Estimated cost: $300-600

Typical onset: 30,000-70,000 mi

Symptoms: burning 1+ quart every 1000 miles, blue smoke on startup, fouled spark plugs, carbon buildup on intake valves, loss of power and misfires

Fix: A subset of engines have piston ring land failures or inadequate ring tension causing oil burning and blowby. Requires head removal minimum, often full short block if cylinder wear is present. Compression and leakdown tests confirm. 30-50 hours for proper fix with new pistons and rings, honing, and valve cleaning.

Estimated cost: $12,000-20,000

Typical onset: 40,000-80,000 mi

Symptoms: external coolant weeping at head-to-block junction, slight oil in coolant (tan residue in reservoir), overheating under load, rough idle when warm, bubbles in coolant reservoir

Fix: Not as common as the bearing failures, but some units develop head gasket leaks on one or both banks, likely from thermal cycling or improper torque sequence during manufacturing. Head gasket replacement requires heads off, resurface check, new bolts, and timing cover work. 18-24 hours labor for both banks.

Estimated cost: $6,500-9,500
