Ford brings a number of year editions to the market under the 6.4 category engine. But among them, some are much appreciated and some have issues. For these issues, some people suggest new buyers to avoid one specific year of the 6.4 Powerstroke.

We tried to take some users’ opinions on their experience of different years of the 6.4 Powerstroke. From that research, we find one year edition has the most complaints against it. We will suggest that you avoid this year.

Common Problems of 6.4 Powerstroke

There is a reputation for the 6.4 Powerstroke to be one of the most successful engines of trucks. This is popular around the world for many reasons. Its fuel injector system, DPF technology and many more features make it one of the best.

But that is not the end of all. Problems are unwanted for all of us. Same problems also came with this Powerstroke too. These problems are like the following.

  • Piston ring failures
  • Higher Pressure on Valve-train
  • Turbo-charger Bearing Seal Failures
  • Higher Incidents of Cavitation Erosion
  • Excessive Wear and Oil Leakage Around the Valves

Which 6.4 Powerstroke Years to Avoid?

From our point of view, there is no year edition of Ford truck that you must avoid. But we think, as you are going to buy only one truck and you want to buy the best one then you have to keep some points in mind.

Almost all the years’ editions have some good and bad sides. But among them, some models have more problems than others. We find a number of complaints against these models from users’ opinions. These opinions came forward from the truck owners. If you want to buy the best one, you may avoid these models.

The year edition that gets the most negative reviews is 2008. This model has got some negative reviews from customers. They blame this for many reasons. Why you should avoid these 6.4 Powerstroke will be discussed below.

Why Avoid This 6.4 Powerstroke Year?

While users talked about the negative reviews after using this model, they also mentioned some reasons there. These reasons are serious enough to avoid this year model of 6.4 Powerstroke. Sometimes these reasons are so serious that they were the main culprit of a number of accidents. Let’s see the reasons.

Steering Seizing

Among the problems that this year edition faces, the most serious one is the steering problem. The problem is so serious that a number of accidents were the result of this. Most of the users complain against this one saying that the 2008 editions seize its steering suddenly without any warning. This happens at the time of the truck’s running.

This allegation is not from one or two users of this truck. A number of people talk about this problem of the 2008 model. That’s why many people are avoiding this model from 6.4 Powerstroke.

Acceleration Problem

The driving experience of this vehicle is also very bad. This was another blame against this model. The acceleration system is not so improved. Some users say that 2008 smokes while accelerating. The smoke is so severe that it is not acceptable anyway.

 Another problem with the acceleration of 2008 is shutting off. Some blame that the engine shuts off while accelerating the engine. Even the engine starts troubling while the truck is in motion. I hope you have enough idea about the seriousness of this problem.

Transmission Problem

The transmission problem is another serious problem that the 2008 users face. Several users of this model say that the transmission seal burns completely very frequently. If you go for a replacement then it will cost you $5000.

Other Problems

Not only the steering, acceleration, and transmission problems, there are so many other problems also in this model. They are like Turbocharger leaks in the Up-Pipe. Weak exhaust backpressure valve that fails frequently and many more.

For these reasons, some users suggest avoiding the 2008 edition of 6.4 Powerstroke. If you don’t want to take any risk in truck buying then you may follow their suggestions. But I don’t think these problems will be true in the case of your truck.


That was all about the worst 6.4 Powerstroke engine. I hope now you know which Powerstroke year to avoid and why you should do that. But I have a different view on this. The performance of an engine depends on a number of things.

So, you can not blame all the vehicles of one model. Maybe some vehicles were faulty. But I think the manufacturer later thought about this seriously and fixed it. But the decision is up to you.
