Problems with 6.7s and Ford has no resolution

So my brand new F250 Powerstroke started bucking and hesitating at 2200 miles. I took it to the dealer and they were baffled. Ford finally flew in an engineer and the guy tells them to put a new MAF on it. Service guy laughed but had to do it since the engineer told him to do to. Sure as sh*t it did not fix the problem. Keep in mind this is after Ford told them just to upload the correct software. Supposedly mine cam with a F450 tune. So I talk to the service manager today and he told me Ford said for me to go pick up the truck as is!!!!! My buddy is having the exact same problem and Ford told them to put a different weight oil in it!!!! I have been on the phone with Ford service for over a month now and needless to say its time I get an attorney

Ford strikes again. The problem is serious enough to fly an engineer out, yet they seem eerily cavalier in their judgement for you to take the truck back without so much as an idea of whats wrong with it.

Not sure if you're aware of these... Just thought I'd post, if not:



TSB 11-12-14
Highlights from TSB:

Issue: Some F-Super Duty F-250-450 pickuptruckvehicles equipped with a 6.7L diesel engine may experience an engine shudder with or without turbo flutter noise around 900-1400 RPM with steady throttle. The issue may be more noticeable at high elevation, high ambient temperature and/or when driving up a slight incline. The concern is not present during regeneration or while using cruisecontrol. Some vehicles that exhibit the concern may set diagnostic trouble code (DTC) P0299.

Service Procedure: 1) Check all continuous memory diagnostic trouble codes (CMDTCs). Are any DTCs present other than the P0299?
Yes - This article does not apply, refer to Powertrain Control/Emission Diagnostic (PC/ED) Manual and continue with normal diagnostics.
No - Proceed to Step 2.
2) Using the IDS, take a recording of the event. Enter data logger and select the following pids:
MAP_A (psi), MAF_A (g/s), EBP (psi)
RPM, APP1 (%), VGTDC (%)
EGRTP_CMD (%)
DPF_REGEN_STAT
3) Road test vehicle and duplicate the concern.
4) Make a recording of the event.
5) Review the recording taken and compare it to figure one located and the end of the article. Does the recording show MAF_A fluctuation with APP1 steady like the figure provided?
Yes - Replace the turbocharger. Refer to WSM section 303-04D.
No - This article does not apply, refer to PC/ED for normal diagnostics.

------------------------------------------------------------------------------------------------------------------------

TSB 12-5-12

ISSUE:

Some 2011-2012 F-Super Duty vehicles equipped with a 6.7L engine and built on or before 5/15/2012 may exhibit diagnostic trouble code (DTC) P0181. Refer to the Calibration Content for additional calibration updates.

ACTION:

Follow the Service Procedure steps to correct the condition.

SERVICE PROCEDURE

Mine does the same thing, and has since new. Dealership doesn't beleive me because they haven't been able to duplicate it, but i am about to jump it off a cliff and collect the insurance and run! This is rediculous, after spending this kind of money. Mine has almost 10k now.

thats bs. ford knows about it and your dealership need to call them to get the info. ask them to give you a data logger. it plugs into your obd port and when your truck does it you hit a button on a controller. it will record 30 sec before and after and will hold 5 logs.

Same Problem - bucking/hesitating - Ford Can't Fix

I thought I was going crazy. I've checked everything. Ford flew in a tech from Denver to SLC to test. I'm told that Ford knows there is an issue but they don't have a resolution. They just gave me my truck back and said they'd call me if they figured something out.

I was told to electronically disable the higher gears so it would run at higher RPM and not have an issue until they could figure something out.

Happens everyday and is frustrating.

I'd love to know if anyone gets resolution from Ford on this and how they did it. I'm eager to know.

Are you in California?? We have a lemon law that I've seen exercised by a few folks without issue.
They weren't new Ford 6.7's, but if it goes to the shop an excessive number of time within so many months under warranty, then they have to replace it!
