The 2022 Defender 110 with the P400 mild-hybrid inline-six is still early in its lifecycle, but we're seeing some concerning patterns with transmission cooling, engine oiling under specific conditions, and electrical gremlins typical of modern Land Rover complexity.
Transmission Oil Cooler Failure
Occasional · high severityTypical onset: 20,000-50,000 mi
Symptoms: Transmission overheat warning on dash, Limp mode activation, especially during towing or spiraling mountain roads, Pink or milky fluid in transmission pan (coolant cross-contamination), Erratic shifting when hot
Fix: Replace transmission oil cooler and flush both cooling system and transmission. If coolant mixed with ATF, may need valve body cleaning or full transmission rebuild. 6-10 hours labor depending on contamination severity.
Estimated cost: $1,800-5,500
Mild-Hybrid System Belt-Driven Starter/Generator (BSG) Bearing Noise
Occasional · medium severityTypical onset: 30,000-60,000 mi
Symptoms: Whirring or grinding noise from front of engine bay on cold start, Check engine light with P0A93 or P0562 codes (hybrid system voltage), Auto start-stop function becomes intermittent or disabled, Battery warning light
Fix: Replace belt-driven starter generator unit (BSG). Requires special programming with IDS/SDD software. 4-6 hours labor including programming.
Estimated cost: $2,200-3,800
Engine Bearing Wear on Early Build Units (Pre-VIN Cutoff)
Rare · high severityTypical onset: 15,000-40,000 mi
Symptoms: Metallic knocking at idle that worsens with RPM, Low oil pressure warning at operating temperature, Metal debris visible on oil filter media or drain plug magnet, Engine oil consumption exceeding 1 quart per 1,000 miles
Fix: Full engine teardown reveals rod bearing or main bearing damage, often from oil starvation during extended spirited driving or off-road angles. Short block replacement or full rebuild with updated bearings. 18-25 hours labor plus machine work if block needs line-honing.
Estimated cost: $12,000-18,000
Transmission Mount Collapse
Common · low severityTypical onset: 25,000-50,000 mi
Symptoms: Clunking when shifting from Park to Drive or Reverse, Excessive driveline vibration at idle in Drive, Visible drivetrain movement when revving in Park, Rubber deterioration visible on inspection
Fix: Replace transmission mount (often the rear mount fails first). 2-3 hours labor. Updated part number available with stiffer compound for off-road use.
Estimated cost: $450-750
Pivi Pro Infotainment System Freezing/Black Screen
Occasional · low severitySymptoms: Touchscreen goes black and unresponsive, Apple CarPlay/Android Auto randomly disconnects, System reboots during drive, Climate controls inaccessible (integrated into screen)
Fix: Software update via dealer SDD system usually resolves. Persistent cases need Pivi Pro head unit replacement. 1.5-2 hours labor for programming, 3-4 hours if hardware replacement needed.
Estimated cost: $200-2,500
Air Suspension Compressor Premature Wear
Occasional · medium severityTypical onset: 40,000-70,000 mi
Symptoms: Suspension fault warning with vehicle sitting low, Compressor runs excessively (audible under vehicle), One corner sags overnight, Extended time to raise from access height
Fix: Replace air suspension compressor and check for leaks at air springs and lines. Compressor failure often secondary to small leak causing overwork. 2-3 hours labor for compressor, add 1-2 hours per air spring if replacing.
Estimated cost: $1,800-3,200
Fuel Filter Clogging (Diesel Models) / Fuel System Contamination
Occasional · medium severityTypical onset: 20,000-40,000 mi
Symptoms: Rough idle and hesitation under load, Check engine light with fuel pressure codes, Hard starting when cold, Loss of power on highway acceleration
Fix: Replace fuel filter and inspect tank for debris or water contamination. Some early tanks had manufacturing debris. If contamination severe, requires tank drop and fuel system flush. 1.5-2 hours for filter, 6-8 hours if tank service needed.
Estimated cost: $300-2,200
Buy with caution: fantastic capability but early adopter risk is real—budget $2,000/year for non-maintenance repairs and ensure full warranty transferability or buy extended coverage.
