My 2008 F350 has 220,000 light duty miles on it. I love the truck, but the engine is on its last legs. I'm pi$$ed to learn that the 6.4 is basically a throw away engine and a reman is going to cost $15K or so by the time I'm done. To say nothing about my 6.4 needing a new fuel system, DPF and radiator while I had it.

So I'm in the market for a new truck. I haven't looked at new trucks in forever. So I test drove a 2017 F350 with a 6.7L thinking I would finally be able to buy a Superduty with a good engine that would outlive the rest of the truck. Because Ford now builds their own diesel engines and the 6.7s are bulletproof, right ?

Wrong !

I walk past the service bay doors and there are two 2011+ Superduties in the bay with the cabs lifted. One has the heads removed. WTH ? I ask the salesman about the 6.7s and of course he tells me what a great engine they are. I point to the trucks in the service bays and he he starts telling me about emissions, fuel quality, abuse, etc. Really ?

So I start talking to truck owners about their 6.7s and I get the same familiar Ford diesel story. "Oh yeah, love the truck and the engine is excellent." "Have you had any issues ?" "Well..."

And then you start getting the real story. Blown turbos, leaking radiators, dropped valves, DEF issues, etc. On the 6.7s ! And the owners always smooth things over by saying the dealer took care of them and it was covered under warranty.

Of course it was ! Most of these trucks are only a few years old ! But what about when these trucks have some real miles on them and the real issues start coming out ?

I remember when the 6.0L came out. It was supposed to be such a great engine. Then people got some miles on them and, well, you know the story.

And then came the 6.4. It was supposed to be bulletproof. Supposedly Navistar fixed all the 6.0 issues with it. And now we find it has issues, it doesn't last much longer than 200K and it is a throw away engine when that time comes.

And then came the 6.7. It was supposed to be the engine that ended the issues, because this time Ford designed it themselves. Millions of miles of testing, extreme duty, blah, blah, blah. But guess what ? The 2011s had bad valves. They've had turbo issues. The radiators leak, just like the 6.4 radiators leaked. WTH ? The DEF systems give problems. The fuel systems can give problems and now I learn that the 2015-16s have an issue with valves during the regen process.

Are you kidding me ?

And the kicker of it all is that when you open the hood there is crap from fenderwell to fenderall, grill to firewall.

One of the main selling points of a diesel engine is supposed to be reliability and longevity. Listen up, Ford. I am not going to sink $75K into a new truck with a questionable engine. Luckily I skipped the 6.0 trucks by keeping my 2000 until I bought my 2008. My experience with the 6.4 has been so so. I purposely waited until the 2017s came out to get my next truck and now I find out the same old song and Ford diesel dance. Sorry, I'm not biting.

I was right there with you but I have friends that are Ford diesel techs who talked me into getting one. They tell me the issues with them are few and far between. Obviously if you are the one having the issue at the moment what I am saying is not likely helpful but I have observed from afar and I have taken the plunge. So far, so good. Easily the most powerful truck I've ever owned. Time will tell.

That's two threads where you're telling us you don't like the 2017's. You're entitled to your opinion and as someone else mentioned in your other thread, there is just no pleasing some people. So what value do you add with threads like this other than trolling.

Did you happen to walk by the service bays of Ram and Chevy and see no diesels on their lifts?? I mean, if someone were to build an absolutely trouble free vehicle, then there would be no contest. Rolls Royce was to be one such company, and yet... So even if you spend a quarter of a million dollars on a vehicle, it will not be trouble free.

Perhaps buying a truck for you is like voting at the polls; checking the box next to the lesser of evils??

If you like your 2008 so well, why not spend that $15k on the engine and continue enjoying it?? That's a far cry from the cost of these new trucks!

Yep, just like every other car on the planet.

1st model year changes will have teething issues. Get the last model year prior to major engine changes and you will have a higher degree of reliability/ less failures.

If you expect eternal perfection in a vehicle (at any price) then you don't understand economics.

Toyota comes the closest to complete long term reliability, but even they have similar issues. I've got two 4.7L V8s that are crazy reliable engines. But that moronic plastic tank/ metal fin radiator design leaks like a sieve just like it does in the Ford SD.

So, you weigh the options and pick the best fit for your needs.

If you could actually build a truck that never wore out in any regard, then you would be in business for a decade and gone. Since no one would ever need a new one unless they crashed the old one.

A vehicle is a consumable tool. Granted with a higher entry ticket and a longer usable life than most. Use it up, recycle it, and buy another.

So, I've documented my issue with the 2014 HPFP and my disgust with Ford. That being said, are those same issues still cropping up in the 2016-2017? I was under the impression that changes were made.

Thanks

Whoever told you the 6.4 was bulletproof was blowing more smoke than a bro truck on a race tune.
The 6.0, believe it or not, is a really great engine, once the problems that crop up are addressed. The problems remained consistent, but the time to failure was the variable, depending on how much fuel was applied, and cylinder pressure wasincreased.
The 6.7 is clean sheet, and the only one like it. Intake is on the low side of the head, exhaust up top, turbo in the valley with short runners. That fixed the exhaust bellows and up pipe problems in short order. The oil system was fixed, the cooler is outside the engine. The cooling system was fixed... a split design to handle the oil and turbo cooling differently than the heads.
Yes, there are some problems, DEF tanks being one, the fuel system being two, IF exposed to water. I'm willing to bet the owners with problems drove the crap out of them, little maintenance, didn't drain the water separator, didn't add anything to the fuel to deal with water.
A FASS system, a DPF friendly tune from DPTuner, and regular maintenance can and will make the 6.7 as close to bulletproof as you can get. Even regular, diligent maintenance stock can get impressive numbers.
You can look and find DuraMax and Cummins problems as well. But you wont find too many mentions like this.

Unfortunately, I am with you man. I will not own a 6.7 or any modern diesel for that matter. It is ridiculous to think that a bad fuel pump may set me back 10K. This is simply unacceptable. This could have been designed differently. One truck is too many to have that issue. Fuel quality is ofter hit or miss. Or the phrase "I need a extended warranty on a 75k truck?" Umm no, that is unacceptable as well. When the 7.3 dies a gasser will replace it.

Sticking to my 7.3 also...it has sort of replaced my old 69 mach1 as my hotrod project as in I'm alright with wrenching on it now and again.

My 2016 has been flawless.. my 2011 6.7 was flawless too. traded at 125k..I work it hard. Trans was clunking then but probably solenoids. The 2017 might have issues with anything other then the 6.7. actually being a new body model year.

Things have gotten too complicated with modern vehicles. It's not just Ford. In fact Ford is probably one of the better ones. The advent of CAN BUS was the game changer. I chased a CAN issue with the wife's Jeep. Dash lights all lit up. Turn Signal on with the switch turned off. Basically not driveable. Turns out after two days of troubleshooting it was the right rear stop/tail bulb. The tail filiment burned out and fell onto the brake light filiment. One new bulb and it was fixed. It would have been a high dollar fix at a dealer or any shop. I got lucky. There is no need for this level of complexity.

I have a theory. Yes I'm a conspiracy theorist but it's not paranoia if they really are out to get you.

If you remember back a few years ago, the OEM's wanted to lock down their software arguing that they are like Microsoft, it's proprietary. The result would be no access for aftermarket shops or retail customers to be able to repair vehicles any more... only the dealer. Obviously, this got shot down.

So my guess is they decided on "plan B"..."since the consumer has such a ferocious appetite for electronic shiny gizmo's....we'll give 'em gizmo's"

Now you have computers telling you how to park, how to drive, your not slowing down quick enough, your slowing too fast, someone is beside you, your trailer is swaying.... and on and on. Bells ringing, lights in mirrors going on and off, it's a freaking circus while driving now.

So if the vehicle is buried in 18 layers of electronics, the knowledge, tools and desire to work on them by retails and small to medium size shops will dwindle funneling more business back to the OE, achieving their initial goal. Not only does this help their business's back end revenue, I'm sure front end margins at the dealers has also improved as electronics are cheap to build and they charge a fortune for most of this stuff. Win-Win for the OE's.

In warranty, there will seldom an issue, but as they age, if this crap can't be disabled without causing issues to safely use the vehicle and all systems have to be maintained, that's going to be a problem.

I drove Ford diesels for 16 years. When it was time to replace my 7.3, there was no way in heck I would have bought another Ford. The 6.0's, the 6.4's and the 6.7's were all having issues. I ended up with a Cummins and have been pleased so far.

There have not been any mentions of major malfunctions regarding the engines, and the fuel systems aren't having problems either. I don't understand how Ford is having so many issues with the fuel system when we are all running the same fuel!
