Common Problems & Known Issues

The 2018 Ford Transit is a workhorse van that suffers from catastrophic engine failures on the 3.5L EcoBoost and transmission cooling issues across the lineup. High-mileage examples often need major powertrain work that can exceed the vehicle's value.

3.5L EcoBoost Catastrophic Engine Failure (Spun Bearings, Piston Failure)

Common · high severity
Typical onset: 80,000-150,000 mi
Symptoms: Sudden loss of power with metallic knocking from engine, Oil pressure warning light illuminates, Metal shavings in oil during changes, Engine seizes or requires immediate shutdown
Fix: Complete engine replacement or rebuild required. This is a known Ford EcoBoost weakness under commercial van loads. Rebuild involves replacing pistons, rings, bearings, crankshaft work. 25-35 labor hours for replacement, 40-50 for rebuild.
Estimated cost: $8,000-15,000

Transmission Oil Cooler Failure / Contamination

Common · high severity
Typical onset: 60,000-120,000 mi
Symptoms: Transmission slipping or harsh shifting, Pink or milky transmission fluid (coolant mixing), Transmission overheating warnings, Coolant loss with no external leaks
Fix: Internal cooler in radiator fails, allowing coolant and ATF to mix. Requires radiator replacement, transmission flush or rebuild if contamination severe. Complete flush is 3-4 hours; if transmission damaged, add 12-18 hours for rebuild.
Estimated cost: $1,200-6,500

Transmission Mount Failure

Common · medium severity
Typical onset: 70,000-110,000 mi
Symptoms: Loud clunk when shifting into drive or reverse, Vibration through floor at idle, Visible transmission sag when inspecting underneath, Driveline shudder during acceleration
Fix: Heavy-duty van loads destroy OEM rubber mounts prematurely. Replacement requires supporting powertrain, typically 2-3 hours labor. Some techs upgrade to polyurethane aftermarket.
Estimated cost: $350-650

Fuel Filter Clogging (3.5L EcoBoost)

Occasional · medium severity
Typical onset: 40,000-80,000 mi
Symptoms: Hard starting or extended cranking, Loss of power under load or uphill, Check engine light with fuel pressure codes (P0087, P0093), Engine stalling at idle after driving
Fix: EcoBoost is sensitive to fuel contamination. Filter is in-tank and labor-intensive to replace. Requires dropping tank, 3-4 hours labor. Ford service interval is too long for commercial use.
Estimated cost: $450-750

Driveshaft U-Joint and Center Bearing Failure

Occasional · medium severity
Typical onset: 90,000-140,000 mi
Symptoms: Clunking noise from underneath during acceleration, Vibration at highway speeds (55-70 mph), Squeaking or grinding sounds when moving from stop, Visible play in driveshaft when inspecting
Fix: Long wheelbase models especially prone to center support bearing failure. U-joints wear from commercial loads. Driveshaft R&R and rebuild is 3-5 hours depending on configuration.
Estimated cost: $800-1,400

Second-Row Seat Latch Recall Issues

Occasional · medium severity
Symptoms: Second-row seats won't latch properly, Seat moves or tips during driving, Latch mechanism feels loose or doesn't engage, Recall notices for seat retention
Fix: Multiple recalls for seat latches failing to hold properly in crash. Even post-recall, some units have recurring latch problems. Dealer repair typically 1-2 hours, but availability of parts has been spotty.
Estimated cost: $0-300

Backup Camera System Failure

Occasional · low severity
Typical onset: 50,000-100,000 mi
Symptoms: Black screen or 'camera unavailable' message when shifting to reverse, Intermittent camera operation in cold or wet weather, Distorted or flickering camera image, Camera works but guidelines missing
Fix: Camera module or wiring harness at rear door fails from moisture intrusion. Replacement is 1-2 hours labor. Check wiring grommet at door hinge first before replacing camera.
Estimated cost: $350-700
Owner tips
  • Change transmission fluid every 40,000 miles regardless of 'lifetime fill' claims—critical for avoiding cooler contamination damage
  • EcoBoost owners: use premium fuel and change oil every 5,000 miles with quality synthetic—these engines do not tolerate neglect
  • Inspect fuel filter and consider replacement at 30,000-40,000 miles on commercial-duty vans
  • Check transmission and engine mounts annually—these wear fast under cargo loads
  • Avoid the 3.5L EcoBoost if buying used with unknown maintenance history; the 3.7L V6 is more durable for commercial use
Avoid high-mileage EcoBoost models unless you have full maintenance records and a $10k repair fund—the 3.7L V6 is the safer used buy.
