Diesel engines don't get much louder praise than the Ford 6.7 Power Stroke V8. Truck nuts love its raw power. Regular drivers notice it too. Still, it's not perfect. Plenty of owners deal with headaches from early models. If you're thinking about renting one, these stories matter. They help you pick smart.
The Allure of Power
The Ford 6.7 Power Stroke packs a punch. It hits 500 horsepower. Torque? Up to 1,200 lb-ft. That lets it pull fifth-wheel trailers weighing 40,000 pounds. Great for big jobs, like hauling gear or dragging an RV. Payload tops out near 6,935 pounds.
Ford rolled it out in 2011. They've fixed bugs along the way. Built it all in-house, no partners this time. The block uses compacted graphite iron. Fuel system runs high-pressure common rail. Solid engineering meets real muscle.
The Problematic Early Years
Even with that background, some owners gripe about breakdowns. 2011 models top the complaint list. Glow plugs fail. Exhaust valves crack too. A busted valve can wreck the whole engine. Forums buzz with those warnings.
Take this one guy's tale. He was towing a trailer. Power cut out cold. No dash light. Engine locked up. Stranded. That's the kind of surprise no one wants, especially if you're renting for a job.
Faulty Fuel Systems
2011s have another weak spot: the injection pump. Bosch CP4.2 units shred themselves. Metal bits contaminate the fuel. Repairs? They run $10,000 or more. One owner got hit with a $10,500 bill to swap the whole system. Ouch. Derails any road trip dreams fast.
Continuing Concerns from 2012 to 2014
Things got a bit better in 2012 to 2014. But not by much. Emissions gear still acted up. The EGR cooler clogged with carbon. That drops power. Temps climb too.
Turbochargers gave out often. The stock one couldn't handle the engine's grunt. Parts wore fast. Broke early. It's like pairing a weak link with a beast. Disaster waits.
Positive Turnaround in Recent Models
Ford listened to the gripes eventually. Newer Power Strokes hold up better. The CP4 pump issue lingers, sure. But overall, they're tougher. Feels like they finally tuned in.

Categories of Common Issues
Owners point to these troubles in the 6.7 Power Stroke over the years. Back in 2011, you'd see glow plug failures popping up left and right, along with those cracking exhaust valves that could trash the engine in a heartbeat, and fuel system meltdowns that left folks high and dry. Then from 2012 to 2014, emissions components started failing more than they'd like, EGR coolers got gummed up with carbon buildup dropping power output while temps spiked dangerously, and turbos just quit too soon under the strain.
| Model Year | Common Issues |
|---|---|
| 2011 | Glow plug malfunctions, valve cracking, fuel system failure. |
| 2012-2014 | Emissions system faults, EGR cooler clogs, turbo failure. |
