The best 6.7 Powerstroke years are 2020 through 2024. These models feature the updated DCR fuel pump and improved turbochargers, eliminating the catastrophic fuel system failures of earlier versions.
Avoid the 2011 through 2014 model years. Early first-generation engines suffer from fragile GT32 turbochargers, dropping exhaust valves, and the notoriously unreliable CP4.2 injection pump.
Rankings are comparative, and no diesel engine is flawless. Meaningful differences exist between configurations, making proper maintenance and a thorough pre-purchase inspection critical for long-term reliability.

How We Evaluated the 6.7 Powerstroke Model Years
Our analysis considers official recalls, manufacturer service campaigns, technical service bulletins, and consumer complaint patterns. We evaluate powertrain changes, generation updates, and repair severity.
Complaints are not confirmed failure rates, and a recall does not automatically make a year unreliable. Recent models have less long-term ownership data. Best means comparatively stronger, not flawless.
Best 6.7 Powerstroke Years
2020-2022 (Best Choice)
Ford replaced the problematic CP4.2 injection pump with the much more reliable DCR fuel pump for the 2020 model year. This update eliminated the risk of metal shavings destroying the fuel system.
The 475-horsepower tuning and revised turbocharger provide excellent towing capability. These years balance modern reliability and strong aftermarket support without the premium price of the newest high-output models.
2023-2024 (Best Late-Generation Choice)
The high-output 500-horsepower engine introduced in 2023 offers massive torque for heavy towing. While the block and fuel system are proven, these trucks have limited long-term ownership history.
They remain excellent choices for buyers needing maximum factory capability. Long-term evidence remains limited, so strict adherence to factory maintenance schedules is essential.
Best Year by Buyer Type
Best Overall: 2020-2022
These years offer the updated DCR fuel system and strong reliability without the premium cost of the newest high-output trucks.
Best Older Choice: 2017-2019
If you must buy an older truck, these models offer the GT37 turbo and higher horsepower. You must verify the CP4.2 injection pump status before purchasing.
Years to Approach Carefully
2015-2019 (Approach Carefully)
Ford upgraded to the larger GT37 turbocharger in 2015, solving earlier turbo failures. However, the Bosch CP4.2 injection pump remained in use through 2019.
If this pump fails, it sends metal debris through the entire high-pressure fuel system. Buyers should only consider these years if the previous owner installed a disaster prevention kit.
Worst 6.7 Powerstroke Years
2011-2014 (Avoid)
The first-generation 6.7 Powerstroke introduced several severe engineering flaws. The GT32 turbocharger is prone to bearing failures and shaft snapping under heavy load.
Additionally, 2011 and 2012 models experienced exhaust valve dropping, which can destroy the engine. Combined with the early iterations of the fragile CP4.2 injection pump, these years carry massive financial risk.
6.7 Powerstroke Reliability by Generation
First Generation (2011-2014)
This generation introduced the 6.7L diesel to the Super Duty lineup. While the block itself is strong, the surrounding components were highly problematic.
The GT32 turbo and early emissions systems caused frequent downtime. Many buyers looking for older diesel reliability prefer the legendary 7.3 Powerstroke instead of these early 6.7L models.
Second Generation (2015-2019)
Ford addressed the turbo issues by introducing the GT37 unit in 2015. Horsepower increased to 440 and later 450, making it a favorite for tuning.
Despite these improvements, the lingering CP4.2 fuel pump issue kept reliability scores mixed. It is vastly superior to the problematic 6.0 Powerstroke, but still requires careful inspection.
Third Generation (2020-Present)
The 2020 refresh brought the DCR fuel pump, new pistons, and a revised turbocharger. This generation is widely considered the most reliable era of the 6.7L engine.
For those preferring gasoline or avoiding diesel emissions systems entirely, the modern Super Duty chassis offers capable alternatives, though buyers should still check F-250 years to avoid for gas-engine quirks.
Common 6.7 Powerstroke Problems
CP4.2 Injection Pump Failure (2011-2019)
The Bosch CP4.2 pump lacks adequate internal lubrication. When it fails, it sends metal shavings into the fuel rails, injectors, and return lines.
This requires replacing the entire high-pressure fuel system, which is incredibly expensive and leaves the truck stranded.
GT32 Turbocharger Failure (2011-2014)
Early models used a complex GT32 turbocharger with ceramic bearings that were prone to premature failure under heavy towing conditions.
A failing turbo can send shrapnel into the engine intake or cause a complete loss of power while hauling heavy loads.
Exhaust Valve Dropping (2011-2012)
Early cylinder heads suffered from valve stem wear and clearance issues. This could cause an exhaust valve to drop directly into the cylinder.
This results in catastrophic engine destruction and requires a complete long-block replacement to resolve.
EGR Cooler Clogging
Like many modern diesels, the exhaust gas recirculation system is prone to soot buildup over time.
Clogged EGR coolers can trigger limp mode and cause overheating issues, requiring regular cleaning or component replacement.
Repair-Cost Overview
| Problem | Commonly Affected Years | Approximate Repair Range | Important Notes |
|---|---|---|---|
| CP4.2 Fuel System Failure | 2011-2019 | $8,000 – $12,000 | Requires replacing pump, injectors, and lines |
| GT32 Turbo Replacement | 2011-2014 | $2,500 – $4,000 | Upgrading to GT37 is sometimes possible |
| EGR Cooler Replacement | 2011-2019 | $800 – $1,500 | Labor intensive due to engine bay packaging |
Repair costs vary significantly by region, labor rates, parts choice, and dealership versus independent shop pricing. Severe damage from a failed fuel pump or turbo can push costs well beyond these estimates.
What to Check Before Buying a Used 6.7 Powerstroke
- Verify the VIN for open recalls and CP4.2 service campaigns.
- Inspect the turbocharger for shaft play and abnormal whining noises.
- Check the fuel filter housing for metal shavings or debris.
- Ensure the emissions system is intact and has not been illegally deleted.
- Test the four-wheel-drive system and check for front-end suspension wear.
- Review maintenance records for frequent oil changes and fuel filter replacements.
- Scan for diagnostic codes using a dedicated diesel-compatible OBD2 scanner.

Frequently Asked Questions
What is the most reliable 6.7 Powerstroke year?
The 2020 and newer models are the most reliable. Ford replaced the problematic CP4.2 injection pump with the DCR pump, eliminating the risk of catastrophic fuel system contamination.
Did Ford fix the CP4.2 pump issues?
Yes, Ford eliminated the CP4.2 pump starting with the 2020 model year. They introduced the DCR fuel pump, which is much more durable and does not destroy the fuel system upon failure.
Why are 2011-2012 Powerstrokes considered bad?
These early years suffer from fragile GT32 turbochargers and a tendency for exhaust valves to drop into the cylinder. Both issues can cause complete engine destruction and massive repair bills.
How long does a 6.7 Powerstroke engine last?
The engine block and rotating assembly are incredibly strong. With strict maintenance, stock emissions systems, and proper tuning, well-maintained examples can reach high mileage, though individual outcomes vary.
Is the 6.7 Powerstroke better than the 6.4?
Yes, the 6.7 is vastly superior to the 6.4 Powerstroke. While early 6.7 models had teething issues, the overall architecture, block strength, and eventual fuel system updates make it much more dependable.
Should I buy a deleted 6.7 Powerstroke?
No. Removing emissions equipment is illegal, voids warranties, and can cause long-term reliability issues. Always buy a truck with intact emissions systems to ensure compliance and avoid severe legal penalties.
Which 6.7 Powerstroke Year Should You Buy?
Target the 2020 through 2024 model years for the best ownership experience. The introduction of the DCR fuel pump and updated turbochargers transformed this engine into a highly capable towing platform.
Avoid the 2011 through 2014 models entirely due to severe turbo and valve train flaws. If considering a 2015 through 2019 truck, verify the fuel system history and budget for potential repairs.
Always perform a strict VIN check, confirm recall completion, and hire an independent diesel technician for a pre-purchase inspection. Proper maintenance remains the most critical factor for long-term Super Duty reliability.
