The 2022 Expedition with 3.5L EcoBoost is a capable full-size SUV, but the twin-turbo V6 carries significant long-term reliability concerns including catastrophic engine failures and transmission cooling issues that can emerge surprisingly early.
3.5L EcoBoost Catastrophic Engine Failure (Piston/Ring/Bearing Damage)
Occasional · high severityTypical onset: 40,000-90,000 mi
Symptoms: Sudden loss of power or engine knock, Metal shavings in oil during changes, White or blue smoke from exhaust, Check engine light with misfire or low oil pressure codes, Abnormal rattling or ticking from engine bay
Fix: Complete engine rebuild or short block replacement required. 20-30 labor hours for rebuild, 18-25 hours for short block swap. Root causes include carbon buildup on intake valves, turbo oil coking, and inadequate oiling under high load. Some failures covered under powertrain warranty if under 60k mi, but many occur just outside coverage.
Estimated cost: $8,500-15,000
Transmission Oil Cooler Failure and Contamination
Common · high severityTypical onset: 50,000-100,000 mi
Symptoms: Transmission slipping or harsh shifting, Pink or milky transmission fluid (coolant mixing), Transmission overheating warnings, Strawberry milkshake appearance in coolant reservoir, Loss of gears or limp mode
Fix: Replace transmission oil cooler (inside radiator), flush transmission and cooling system, sometimes requires full transmission replacement if contamination severe. 8-12 hours labor for cooler and flush, 16-22 hours if transmission rebuild needed. The 10R80 transmission does not tolerate coolant contamination.
Estimated cost: $2,800-9,500
Fuel Pump Failure (Low-Pressure Module)
Occasional · high severityTypical onset: 30,000-70,000 mi
Symptoms: Engine stalling or no-start condition, Hesitation or stumbling under acceleration, Check engine light with fuel pressure codes (P0087, P0230), Engine cranks but won't fire, Loss of power at highway speeds
Fix: Replace in-tank fuel pump module. 3-4 hours labor to drop tank and swap module. Ford issued recall 21S45 for some VINs, but many units fail outside recall scope. High-pressure pump on engine can also fail but less common on 2022s.
Estimated cost: $1,200-1,800
Integrated Trailer Brake Controller Malfunction
Common · medium severitySymptoms: Trailer brakes engaging randomly without input, Brake controller error messages on dash, Trailer brakes not responding when towing, ABS or stability control warnings with trailer connected, Brake pedal pulsation when towing
Fix: Software flash or module replacement. Multiple recalls (21S24, 22S37, 22S66) address this. 1-2 hours for software update, 2-3 hours if module replacement needed. Affects towing safety significantly. Dealer-only repair due to programming requirements.
Estimated cost: $0-650
Transmission Mount Failure
Common · low severityTypical onset: 40,000-80,000 mi
Symptoms: Clunking when shifting from park to drive/reverse, Vibration at idle in gear, Excessive driveline movement over bumps, Thud felt through floor during acceleration, Visible sagging or tearing of rubber mount
Fix: Replace transmission mount(s). The rear mount takes most abuse on heavy SUVs. 1.5-2.5 hours labor depending on which mount. Often overlooked until severe. Use OEM or upgraded polyurethane mounts for longevity.
Estimated cost: $350-600
Windshield Wiper Linkage Binding/Failure
Occasional · medium severityTypical onset: 20,000-60,000 mi
Symptoms: Wipers stop mid-cycle and won't park, One wiper moves slower than the other, Clicking or grinding from wiper mechanism, Wipers work intermittently or not at all, Wiper motor runs but blades don't move
Fix: Replace wiper linkage assembly or bushings. 2-3 hours labor to remove cowl and access linkage. Recall 22S32 covers some units. Common on Expeditions due to cowl design trapping debris and moisture. Motor itself rarely fails.
Estimated cost: $450-750
Buy only with comprehensive warranty coverage or budget $3,000-5,000 for inevitable repairs between 50k-100k miles; the EcoBoost engine and 10R80 trans combo is powerful but not durable under real-world heavy-duty use.
