I don't know much about the 6.7L. I know that in years past there have been a lot of problems in the super duties. I drive a 97 7.3 and love it. I was wondering if anybody has any problems with the 6.7, how it stacks up against the 7.3, and how long it's built to last for. Any help is appreciated, thank you.

 

Any time you build a more complex engine you will have more chance for failures. So I think the opportunities are there for the 6.7L to have more problems than the 7.3L. But it is a much better engine, More power, Better mileage, quieter etc.

I'm at 82,000 miles and other than oil changes and a couple of software updates, It has not seen the dealer. That right there is better than my 7.3L or 6.0L ever did.

 

Newer sometimes IS better

Am on my second 6.7 and the first one in 45k miles never had a hiccup... the new one only has 700 miles so looking forward to using it up !

 

Love my 2011!

 

Thanks for the help keep it coming! I'm not really worried about the first 100 thousand miles or up to 200 because I'm sure it runs great then. Has anyone gotten really high miles on it yet? I'm not looking to own my truck for only 10 or even 20 years, you buy a truck like this to last you as long as possible, it's not like buying BMW this is a work truck. I've got 300 thou on my 7.3 and can probably put oner 400 or 500 thou on it. How long are these trucks made to last?

 

Well there's a video on YouTube of one with 500,000 miles

My only complaint is the 2011 job 1 transmissions.
I've not had the best luck with that piece of hardware on my truck.
My 6.7L engine, however, is flawless thus far.
I did lose my turbo driving down the highway awhile back but that was a PCM firmware issue and not hardware so that doesn't count as an engine repair.

I certainly wouldn't hesitate to purchase a 2013 if I were in the market.

 

Drive your 7.3 to the 400 or 500 thou and by then you will know if theses engines are holding up or not. I bought a 2012 and its ok, I really wish I could redo parts of this truck. Things I don't like: 6 speed transmission, electric throttle (not as responsive at times) and the brakes on the 2012 are anemic. Other than that I'm happy with it so far.

 

Have my 2012 truck for about a year now with 35,000 miles and lotsa custom work. Haven't had one warranty issue yet!! My '05 6.0l had all kinds of problems in the first year.

 

Funny how that works. My '05 6.0 was a fantastic truck and I wish I still had it.

That said, the engines in these trucks are spectacular. My transmission.....not so hot. Regardless of my issues though, I still maintain that these are the best HD trucks on the road and if I were in the market for one, I'd definitely get another. I think they've gotten the issues with the transmissions worked out by now.

 

Hi John.
How goes it? Good to see ya here. I've noticed you on some of the other FTE Forums. Staying busy helps pass the time.

I have to ask tho, what issues? I thought FORD told you it was normal for our trucks to shift like a teenage school girl trying to learn how to drive a standard transmission, and have shift flares whereby when you step on the throttle, all you get is high rpm's and no tranny engagement. If that's not normal then why did they have to, "work out any issues"?

I know, I'm being a smart alek, but if there wasn't anything wrong before, why did they make changes?

Hope your ordeal is nearing satisfaction.

 

Howdy Ron!

You hit the nail on the head. I purposely stay out of threads like this most of the time because I'm not going to gloom and doom and bring everyone down.

And truly, I believe I got the "one truck out of xxx trucks" that had issues. I don't think it's the norm but Ford needs to handle it better. I had the same questions you just asked and I asked them why they did over $3k in parts and labor (under warranty) in one visit alone, if it was all normal. I got the standard response....."It's operating as it should and these are normal operating characteristics of the transmissions in these trucks". The issues with mine go a lot deeper than this but I won't clog the OP's thread with the details.

All of those questions are great but unfortunately, no one at Ford has been able to answer any of them for me.

And yes, my situation is about to be resolved within the next week with any luck. Thanks for asking buddy.

I'll stop back by the WIH thread tomorrow sometime.

To the OP....sorry for the hijack.

My advice is get what will make you happy and get the job done and if that's the Super Duty, go for it. Like I said, I wouldn't hesitate to buy another if I needed it in the future.

 

I think the early build 2011's had some issues. I had a few problems with mine. I had a turbo oil leak, DEF pump and tank replaced, both batteries & starter. I traded mine on a 2013 a couple of months ago. Although I had a few problems I think they are very reliable for the most part. I absolutely love my truck. Lots of power, good fuel economy & fun to drive.
I think if you buy one you will be very pleased.

 

Indeed, my apologies as well to the OP.

My truck is a job 1 June 2010 build date. I have almost 36000 on my truck and have had a few issues. One is the tranny shifting. After a couple computer flashes and changing out the solenoids and a fluid swap, mine is pretty much the same as it has been. Herky jerky, clumsy and once in a while embarrassing. But for the most part, it works fine.

The shocks and the steering stabilizer are junk and should be replaced as soon as you can afford to. It took three trips to a local alignment shop to get my truck to quit the early death wobble effect it had.

The spring rates on these trucks are pretty weak. If you load them up heavy, you can expect a shudder in the rear end upon take-off. It's a driveline angle issue. You can shim the rear axle to change the angle when loaded, but then you have the problem when empty. Some folks have had good results using airbags to supplement the weak spring rates.

There have been a few turbo issues and a few valve train issues. Again, most of those in the 2011 range models.

There are a few High Pressure Fuel Pump, HPFP, issues too, but I think some of those have been mis-fuel problems caused by the owners.

I don't mean to come across wrong. The truck is pretty solid. I just don't like doing R&D for a major Corp, and then when you try and seek warranty help, you are told there is nothing wrong. Then in the next model year, they make changes and address the issue the previous year reported without consideration to the previous model years.

There are problems with all brands. Pick the one you want and feel most comfortable with. They will all get the job done.

 

I agree with Ron.

One thing I did learn about this is that buying a first year model isn't always a wise move. Some folks have had great experiences with 2011 models while a few others have not. I'll wait a year or so from now on when a vehicle is introduced before I buy. Not saying all '11s are bad. There are many, many great 2011 SDs out there and many, many happy owners.

All in all though, you should be good to go with a 2013 model. The major kinks should be worked out now and I really don't recall reading any complaints or problems with them so far.
