The 2024 F-250 Super Duty is still too new for widespread pattern failures, but early adopters are seeing some concerning trends with the 6.7L Power Stroke's fuel system and the 10R140 transmission's cooling circuit. The 7.3L gas motor has been more trouble-free so far.
10R140 Transmission Oil Cooler Failure
Occasional · high severity
Typical onset: 40,000-80,000 mi
Symptoms: transmission fluid mixing with coolant creating milkshake in overflow, erratic shifting or limp mode, transmission overheating warnings on dash, coolant loss with no visible external leak
Fix: Internal cooler failure allows cross-contamination. Requires complete transmission flush, cooler replacement, radiator flush, and often full trans rebuild if milkshake circulated long. 8-14 hours labor depending on contamination severity.
Estimated cost: $2,800-6,500
6.7L Power Stroke CP4.2 Fuel Pump Failure
Occasional · high severity
Typical onset: 60,000-120,000 mi
Symptoms: sudden loss of power and rough running, metal shavings in fuel system, hard starting or extended cranking, fuel in oil causing dilution, check engine light with low fuel pressure codes
Fix: CP4.2 pump grenades internally, sending metal through entire fuel system. Requires pump, injectors (all 8), fuel lines, tank cleaning, sometimes lift pump. Catastrophic and expensive. 18-24 hours labor.
Estimated cost: $8,500-12,000
6.7L EGR Cooler Clogging and Cracking
Common · medium severity
Typical onset: 80,000-140,000 mi
Symptoms: white smoke at startup, coolant loss with no visible leak, rough idle when cold, check engine light with EGR flow codes, coolant smell from exhaust
Fix: EGR cooler clogs with soot or cracks internally leaking coolant into exhaust. Replacement requires cab removal on some configurations or pulling engine accessories. 6-10 hours labor depending on access.
Estimated cost: $2,200-3,800
Transmission Mount Deterioration
Common · low severity
Typical onset: 50,000-90,000 mi
Symptoms: clunk when shifting from park to drive or reverse, vibration at idle in gear, excessive driveline movement felt through floor, visible cracking or separation of rubber mount
Fix: Heavy-duty use and torque from diesel destroys rubber mounts prematurely. Straightforward replacement, access is decent. 1.5-2.5 hours labor.
Estimated cost: $350-650
6.7L High-Pressure Fuel System Contamination
Occasional · medium severity
Symptoms: rough running and misfires, extended cranking especially when cold, reduced power and black smoke, multiple injector fault codes
Fix: Water or debris in diesel fuel wrecks injectors and pump seals. Usually requires replacing all 8 injectors and fuel filters, sometimes CP4 pump seals. Prevent with quality fuel and regular filter changes every 10k. 8-12 hours labor.
Estimated cost: $4,500-7,000
DEF System Heater and Sensor Failures (6.7L)
Occasional · medium severity
Typical onset: 70,000-110,000 mi
Symptoms: DEF quality warning on dash, speed limited to 55 mph after warning countdown, poor DEF system performance in cold weather, check engine light with NOx sensor codes
Fix: DEF tank heater fails or level/quality sensors give false readings. Can trigger limp mode if ignored. Tank access varies by bed config. 2-4 hours labor for heater, 1-2 hours for sensors.
Estimated cost: $600-1,400
Owner tips
Install a CP4 fuel pump bypass kit on the 6.7L diesel ($500-800) to prevent catastrophic fuel system failure—it's cheap insurance
Change fuel filters religiously every 10,000 miles on the diesel, use quality fuel from high-turnover stations
If towing heavy regularly, install auxiliary transmission cooler to protect the 10R140—factory cooler is marginal
Delete the EGR on the 6.7L if legal in your state and you're keeping the truck long-term—controversial but eliminates cooler failures
The 7.3L gas motor avoids most of these diesel headaches if you don't need the torque or towing capacity
Buy the 7.3L gas if you can live with lower towing capacity—it's proven more reliable; if you need the diesel, budget $2-3k annually for inevitable fuel system and emissions repairs after 60k miles.
