Never had the issue with my 11 F250 however my brother in-laws 12 F250 has had them go out several times. He was told its caused by excessive idling ( deal claim).

I had 3 of the 6.7s now only 2 and have had this happen multiple times. None of the trucks have over 30k miles on them. Simple fix according to local ford dealer. "Just put a bunch more highway miles on them and you won't have this problem." I said f u and I am cutting off all exhaust filter crap as soon as warranty is up. And they blow fuses to trailers all the time. All 3 of mine, my dad's f450 and my buddies f350 blew the same fuses. I still love the trucks though.

I got told the same thing when I had my 2011. My drive to and from work is only 12 or 13 miles so it would rarely kick into regen or wouldn't complete regen and ended up going into limp mode on me a couple of times.

Now I've got a 5.9 Cummins and don't have to deal with the def/dpf/egr bs. But, all in all the 6.7 power stroke is a nice truck.

Man, ford just dove head first into a diesel hole from hell and cant climb out.... Back in the early 90's I had a ford 6.9 boxvan for racing and you couldnt kill that thing if you had to. They dont make em like that anymore.

2012 f250 with 49k, but i dont think lack of idling will get me. I commute into New Orleans daily for a 80 mile round trip. No issues yet..

i have a 2011 f350 with 22,500 miles,no problems....yet.

We've got a dozen of these newer ford's at work. F550 crew cabs. Apparently they've had their share of problems from what I've heard. The trucks they are phasing out of the fleet with these, are older F350 crew cabs, with V10's. The older V10 trucks, have served them well, very reliable, according to the mechanics. These trucks spend most of the day idling, or simply getting beat on by the drivers. The older V10 trucks mostly have 80-130k miles on them, but tons of hours. Supposedly the purchasing dept is rethinking the diesel powered pickups after the recent purchase of these newer fords for this kind of use.

2011 80K no problem. Lots of short trips. I am listening. 0 defects.

11 F450 100,000 miles now... no problem with EGT... but Rad started leaking just out of warranty... few other small things but the truck has been good overall
lots of idling... now that I posted this somethings going to happen to it.... LOL

Truck is way way too complicated under the hood........fans/radiators/sensors everywhere!

My 03 Duramax was bone stock and went 170K miles. Here was the total repair list:
1. 106K miles, water pump
2. 132K miles, one front wheel bearing (I changed both and did front brake pads while it was apart)
3. 155K miles, injectors covered under GM extended warranty (zero cost to me)
4. 165K miles, pulley failed, needed to be towed/new pulley and belt
5. 200K (I traded it, new owner told me he had only done a gauge cluster (used off ebay $25)

Did 2 sets of batteries and 3 sets of tires in my ownership but I would consider those wear items not repairs.

Now maybe I had good luck or got a good truck off the line but this would be my expectation owning a new 50-60K pickup......certainly not the nonsense listed above. BTW not a Ford hater, I traded the GMC for a new Ford back in 2011.
