Same problem...6th service visit...long post

2012 350 4wd ext cab short bed XL purchased july 3rd of 2013 new. Shudders on incline in 5th. Worse in 6th. Between 45-70mph. Very intermittently. Took it in to dealer I purchased it at first time at around 6200 miles. Was told there was a tsb for trans. Got truck back next day. Week or so later doing it again. Slightly worse. Took it back again 2nd time. This time diesel tech got it instead of trans tech. Said there was another tsb out for similar complaints during regen. Got it back two or three days later. Week later it's doing it again and worse. Took it back 3rd time. After 1.5 wks of dealership driving it around with it only doing it mildly once Was told tech dialog was created by tech to find out what engineer wanted to do. No cels or any lights of any source mind you. Does it in regen AND NOT in regen. Engineer said install flight recorder and return truck to me. Made 4 recordings in 2 weeks and took it back for 4th visit. Engineer said data was corrupted on flight recorder however enough was used to determine bad turbo. Turbo replaced at 7600miles. Driving same day as getting truck back, only 89 miles since I got it back it from dealer it does it again but severely. Tues morning I take it back (5th time) and was told they were going to ask engineer what to do next and to keep truck till they find something else. Driving home from work this afternoon it does it so violently at 70 mph it actually knocked so bad it shut off and stranded me on side of interstate. Have vehicle towed back for 6th visit. Contacted ford customer care to find out what can be done and they tell me someone will contact me within two days to discuss fixing truck. Meanwhile I'm paying for a F350 driving a focus. 6 service visits for same complaint since bought in July. Truck still not fixed. Spoke with field engineer in person and he said its due to my driving habits. I don't need to baby it. Quote Russ Pryor ford field engineer "drive it like you stole it"... And that I needed to add fuel additive as well after they replace my exhaust valves. So I own a f350 with 7700 miles that I've had 3 months and it's been at ford so many times my presets are still on rental cars radio. I paid 44k for a truck I have to drive like I stole and add an additive after each fill up????? Somebody needs to give me advice on what to do. I know ford won't pay my tickets for "driving like I stole it"....

I share your frustration with this issue! The suggestion that your driving style causes it is BS. I do drive mine hard when I can and as soon as conditions are right it does this crap again. If these trucks need to be driven hard at all times then they haven't been engineered correctly. Just curious, do you have the 331 rear axel?

Don't know bud. I'll have to dig out the window sticker when I get it back. They are pulling cab right now to remove heads and change exhaust valves.

I've heard the cause of the issue blamed on everything from driving style, to waste gate adjustment, to exhaust valve issues, etc....... In this day of technology and diagnostic capability, I think it's ridiculous that this problem hasn't been identified and resolved. This issue has been present on some trucks since the introduction of the 6.7 in late 2010. If the new '15s have addressed this issue then Ford should be required to retro fit and fix the issue on the earlier models with the problem. I tried to trade for a gaser Friday. I was only offered $42K for a truck that stickered for $56K three months ago when I bought it new. If I could have traded without getting screwed I would have done so. I guess my only recourse is to continue to return it to the dealership in an effort to document a Lemon Law case. I hate the damn thing!

I agree. My turbo was replaced and they said the wastegate was all messed up. Then why is it still doing it? Now it's my driving style and exhaust valves? How does exhaust valves cause an intermittent problem? Either way I think this is a problem that Ford moco doesn't want to address. I'm having loads of assistance through my dealer. They really are doing everything they can do to help me. However FoMoCo is useless. I will never buy another new ford ever again. I've had wreckers, multiple super duties, etc. this is the first new one. Won't make that mistake again.

Ok so now my warranty has been moved to 7 yrs and 200k miles. However they've ordered parts and aren't going to work on my truck till tomm. So I've been without my truck for another week driving a focus and they tell me that even pulling the cab off and the heads off won't guarantee this fixes it.

theres a TSB about replacing the exhaust valves on the left cylinder head.
From what I understand, when it starts its regen cycle part of the strategy is to dose the left bank with fuel. The added fuel is apparently driving up the cylinder temp to the point that the exhaust valves are sticking slightly.
This is why when the problem is recorded on a datalog, it commonly gets misinterpeted as a turbocharger surge and/or wastegate issue. Its actually the drive pressure on the turbine wheel varying wildly due to the sticking valves. The turbo is just reacting

Poor man, then why does mine do it not in regen, and when I shut it off immediately after it does it nd cut it back on it runs fine? I can shut it off while rolling and cut it right back on and it's fine.

man I dunno why it does it not in regen. but if it was in regen and acting up and you cycle the key, im sure its gonna stop the regen cycle due to cycling the keyswitch.
Thats crazy, hope you get it fixed.
did they get all the parts in? at one time, the head gaskets were on backorder.
