All 7 Known Issues
The EGR (Exhaust Gas Recirculation) cooler on 2011-2019 6.7L Power Stroke diesel engines is prone to clogging with soot and eventually failing, particularly on trucks used for highway driving, light loads, or trucks that idle extensively. The EGR cooler recirculates cooled exhaust gas back into the intake to reduce NOx emissions. Over time, soot accumulates in the cooler's internal passages until coolant flow is restricted, causing the cooler to overheat and fail. When it fails, exhaust gases enter the coolant system, causing overheating and "puking" coolant from the degas bottle. The 2011-2014 models are particularly susceptible due to narrow internal coolant passages. Ford issued TSBs for 2011-2014 trucks covering EGR cooler cleaning/replacement under extended warranty up to 120,000 miles. The EGR cooler for 2011-2016 is OEM part BC3Z-9V425-A; 2017+ is HC3Z-9V425.
Common Symptoms
- Coolant loss with no visible external leak
- Coolant reservoir overflows or "pukes" coolant
- White smoke from exhaust (coolant in combustion)
- Engine overheating warning
- DTC codes P0401 (Insufficient EGR Flow) or P2457 (EGR Cooler Performance)
- Bubbling or foaming in coolant degas bottle
- Loss of power under load (especially towing)
- White deposits around degas bottle cap
How to Fix
Replace EGR cooler (BC3Z-9V425-A for 2011-2016; HC3Z-9V425 for 2017+). Check if truck qualifies for Ford extended service coverage with active DTC P0401 (Insufficient EGR Flow) or P2457 (EGR Cooler Performance). Some 2011-2014 trucks covered to 120,000 miles. Preventive: use a fuel additive (Diesel Kleen, Hot Shots Secret EDT) to reduce soot. Perform regular EGR cleaning at 60,000-mile intervals. Upgrade kits from Sinister Diesel and Dorman (904-405 kit) include both EGR cooler and gaskets.

Parts and tips from 3,450+ owners who fixed this issue
- TipEGR cooler OEM part numbers: 2011-2016 use BC3Z-9V425-A; 2017+ use HC3Z-9V425. The Dorman 904-405 kit is a complete drop-in replacement with gaskets for 2011-2016 at ~$200-$300, well-reviewed on FordTruckEnthusiasts. Labor is 4-6 hours on 6.7L.
- NoteWhen the EGR cooler fails, coolant enters the combustion chambers. If you see the degas bottle overfilling and white smoke from the exhaust, stop driving IMMEDIATELY. Continued operation can hydrolock the engine and cause $15,000+ in damage.
- TipFord extended service coverage applies to 2011-2014 trucks with active P0401 or P2457 codes up to 120,000 miles. Bring truck to dealer with these live codes for potential free repair. Check powerstroke.org for current status of extended coverage.
The 2011-2016 6.7L Power Stroke uses a Bosch CP4.2 high-pressure fuel injection pump that is fundamentally incompatible with North American diesel fuel specifications. US diesel fuel has lower lubricity than European fuel, and the CP4 pump relies on fuel for internal lubrication. Over time, the CP4 pump's internal metal components grind and generate metal shavings that are distributed throughout the entire high-pressure fuel system at 30,000+ PSI. Metal contamination destroys all downstream injectors, fuel rails, and low-pressure system components. A class action lawsuit filed against Ford alleges the company knew the CP4 was incompatible with US fuel. Catastrophic failure can occur as early as 80,000-120,000 miles and requires complete fuel system replacement costing $8,000-$15,000.
Common Symptoms
- Loss of power during acceleration
- Engine hesitation and stumbling under load
- Hard start or no-start condition
- Smoke from exhaust (black or white)
- Check engine light with fuel system pressure codes
- Loud ticking or knocking from injector area
- Fuel rail pressure too low codes (P0087, P0191)
- Complete engine shutdown on the road
How to Fix
Complete fuel system replacement required: CP4 pump, all 8 injectors, high-pressure fuel rails, low-pressure pump, fuel filter housing, all fuel lines (metal contamination spreads everywhere). Ford kit EC3Z-9B246-C covers the repair for some years. Total cost $8,000-$15,000. Prevention: add diesel fuel lubricity additive (Stanadyne Performance Formula, Hot Shots Secret DIESEL EXTREME) at every fill-up. Some owners install a CP3 conversion pump kit (eliminates the CP4 with a more reliable Bosch CP3).

Parts and tips from 1,870+ owners who fixed this issue
- NoteCP4 failure is a total fuel system contamination event - NOT just a pump replacement. Every component that touched the contaminated fuel (injectors, rails, lines, filter housing) must be replaced or metal particles will destroy the new pump immediately. Ford EC3Z-9B246-C kit is the correct repair package.
- TipPREVENTION is key: add Stanadyne Performance Formula or Hot Shots Secret DIESEL EXTREME at every fuel fill to raise diesel lubricity. This is the most cost-effective insurance against CP4 failure. Cost: ~$5-$10 per tank vs. $10,000+ repair. Many 6.7 owners do this from day one.
- TipCP3 conversion kit eliminates the problematic CP4 and replaces it with the more durable Bosch CP3 design. Kits from Driven Diesel, Industrial Injection, and others run $800-$1,500 installed. Ideal preventive measure especially for trucks used for towing or performance applications.
The 2011-2014 6.7L Power Stroke uses a Honeywell DualBoost variable geometry turbocharger with ceramic bearings that proved unreliable in real-world use. The ceramic bearings fail prematurely, especially under hard towing use or when oil change intervals are stretched. The variable geometry turbo's complex actuator mechanism also sticks or fails. When the turbo fails, it is unmistakable: a deafening screeching sound accompanied by smoke from the tailpipe as the engine burns oil through the failed turbo seals. Ford recognized the early turbo design was problematic and switched to a single-compressor-wheel variable geometry turbocharger in 2015, which is significantly more reliable. Retrofit kits for 2011-2014 trucks are available.
Common Symptoms
- Loud, deafening screeching or wailing noise from engine compartment
- Blue/black smoke from exhaust (oil burning through failed turbo seals)
- Significant loss of power - engine goes into limp mode
- Check engine light with turbocharger-related codes
- Boost pressure too low codes (P0299)
- Excessive oil consumption
- Oil in intercooler or intake tract
How to Fix
Replace turbocharger with updated 2015+ style single-compressor VGT unit using a retrofit kit (available from Drivingline/Banks Power aftermarket suppliers). OEM replacement of original DualBoost turbo is $2,500-$4,000 for the unit alone, plus 4-6 hours labor. Updated single-scroll VGT from 2015 is more reliable and kits allow installation on 2011-2014. Critical: always let turbocharged diesel idle for 3-5 minutes before shutdown to allow turbo bearing cooling.

Parts and tips from 1,240+ owners who fixed this issue
- NoteIf you hear a loud screeching from the engine bay on a 2011-2014 6.7 Power Stroke, stop driving immediately. Continuing to drive a failed turbo will push large amounts of oil into the intake manifold. If oil reaches the cylinders and the engine runs on its own oil, you can experience a "runaway diesel" which can destroy the engine.
- TipAlways idle your 6.7 for 3-5 minutes before shutting off after any hard work (towing, long highway drives). The turbo spins at 100,000+ RPM and ceramic bearings need oil to cool down. Abrupt shutoffs are a leading cause of premature bearing failure.
- TipConsider the DrivingLine/Banks Power 2015-style single-scroll VGT retrofit kit for 2011-2014 trucks. It replaces the problematic DualBoost design with the more reliable 2015+ turbo architecture. Cost is similar to OEM replacement but with significantly better long-term reliability.
The Selective Catalytic Reduction (SCR) system on 2015-2022 6.7L Power Stroke trucks - which uses Diesel Exhaust Fluid (DEF) to reduce NOx emissions - is prone to failure, most commonly triggering DTC codes P207F (Reductant Quality Performance) and P20EE (SCR NOx Catalyst Efficiency Below Threshold). Causes include degraded or crystallized DEF fluid (DEF has a shelf life of 1-2 years and degrades faster in heat), a failed DEF injector, SCR catalyst failure, DEF quality sensor failure, or NOx sensor failure. In limp mode, the truck's performance is severely limited. The system is complex and diagnosis requires a professional scan tool. The DEF injector is a particularly common failure point on 2017+ trucks.
Common Symptoms
- Check engine light with P207F (Reductant Quality Performance) code
- Check engine light with P20EE (SCR NOx Catalyst Efficiency Below Threshold)
- Reduced engine power / limp mode
- DEF gauge or warning light showing issue
- Truck will not restart after excessive limp mode cycles
- Rough running at idle
- Increased fuel consumption
How to Fix
Diagnose with Ford IDS or quality OBDII scanner capable of reading all PCM codes. Common fixes: (1) Drain and refill DEF tank with fresh fluid (AutoZone DEF, Ford Motorcraft DEF VC-10-B) - $15-$30. (2) Replace DEF quality sensor ($150-$300). (3) Replace DEF injector ($300-$600 + labor). (4) SCR catalyst replacement ($2,000-$4,000). Always use fresh, quality-brand DEF (avoid bargain/store-brand DEF). Do not let DEF tank run to empty repeatedly.

Parts and tips from 1,560+ owners who fixed this issue
- TipP207F almost always starts with degraded or contaminated DEF fluid. First fix: drain and completely refill the DEF tank with fresh Motorcraft DEF VC-10-B or a name-brand DEF. Cost is $15-$30. This clears the code in 30%+ of cases. Do not buy bargain DEF from no-name brands.
- NoteP207F is a "conditional code" - the PCM monitors must complete 3 consecutive drive cycles without fault before it clears. Simply erasing the code without fixing the root cause will just set the code again. Diagnosis requires a capable scan tool that reads all PCM monitors.
- TipPrevent DEF issues: use Motorcraft VC-10-B DEF or major brands (BlueDEF, Peak Blue DEF). Replace DEF every 12-18 months even if level is fine - DEF degrades over time especially in heat. Never let the tank run completely dry as this can crystallize deposits in the injector.
The 7.3L diesel engines (IDI pre-1994, Powerstroke 1994+) experience injector failure causing rough running, hard starts, and excessive smoke. The IDI injectors are simpler mechanical units; Powerstroke uses HEUI hydraulic electronic injectors.
Common Symptoms
- Hard starting
- Black or white smoke
- Rough idle
- Knocking noise
- Loss of power
How to Fix
Glow plug failure is common on 7.3L diesel engines, causing hard cold starts. The glow plug relay (solenoid) also fails, preventing power from reaching functional glow plugs. Broken glow plug tips can also fall into the cylinder.
Common Symptoms
- Hard starting in cold weather
- Extended cranking
- Wait-to-start light stays on
- White smoke on cold start
How to Fix
The Ford F-250 Super Duty (1999-2016) is notorious for premature front ball joint failure, a well-documented issue across all Super Duty forums. The heavy front-end weight from diesel engines (7.3L, 6.0L, 6.4L, 6.7L Power Stroke) combined with coil spring or leaf spring front suspension designs puts excessive stress on the upper and lower ball joints. RepairPal estimates ball joint replacement between $585 and $1,640 depending on model year. The 2005-2016 models with the coil spring front suspension appear most affected. Symptoms include clunking over bumps, loose steering feel, and uneven front tire wear. In severe cases, a completely failed ball joint can cause the wheel to tuck under the vehicle, resulting in loss of steering control. NHTSA has investigated ball joint complaints on various Super Duty model years. SuperDutyPSD.com provides a detailed ball joint replacement procedure documenting the issue.
Common Symptoms
- Clunking or knocking noise when turning or going over bumps
- Steering feels loose or wanders
- Uneven or accelerated front tire wear (inside or outside edge)
- Creaking noise from front suspension
- Vehicle pulls to one side
- Steering wheel vibration at highway speeds
- Visible play when rocking front wheel by hand (jack test)
- Front end feels unstable over rough roads
How to Fix
Replace upper and lower ball joints as a set on each affected side. OEM ball joints are adequate for stock vehicles, but heavy-duty aftermarket options (Dynatrac Free-Spin, Synergy, or Dana/Spicer heavy-duty) last significantly longer for trucks used for towing or off-road. RepairPal estimates $585-1,640 depending on model year and shop. DIY cost is approximately $300 in parts. Always perform a front-end alignment after ball joint replacement. Inspect tie rod ends, wheel bearings, and track bar bushings at the same time - these related components often wear together.
What Owners Are Using
Parts and tips from 5,800+ owners who fixed this issue
- TipStock Ford ball joints on Super Duty trucks are barely adequate for the front-end weight, especially with diesel engines. When replacing, upgrade to Dynatrac Free-Spin or Dana/Spicer heavy-duty ball joints. They cost $50-100 more per side but last 2-3x longer. Do both sides at once.
- NoteA completely failed ball joint on a Super Duty can cause the front wheel to tuck under the truck, resulting in catastrophic loss of steering control. If you hear clunking from the front end or feel loose steering, inspect ball joints immediately. Lift the front wheel and check for play - any detectable movement means replacement is needed.
