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:
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 (%)
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.
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.
Follow the Service Procedure steps to correct the condition.
Please run Oasis using the Vehicle Identification Number (VIN) to search for open Field Service Actions (FSA) and claim reprogramming updates against open FSA's when applicable. The latest level includes all previous enhancements released in prior calibration levels.
Reprogram the powertrain control module (PCM) and the transmission control module (TCM) to the latest calibration using IDS release 79.01 and higher. This new calibration is not included in the VCM 2012.5 DVD. Calibration files may also be obtained at Buy Motorcraft Parts Online | Official Motorcraft Auto Parts Site | FordParts.com.
NOTE: PLEASE ADVISE THE CUSTOMER THAT THIS VEHICLE IS EQUIPPED WITH AN ADAPTIVE TRANSMISSION SHIFT STRATEGY WHICH ALLOWS THE VEHICLE'S COMPUTER TO LEARN THE TRANSMISSION'S UNIQUE PARAMETERS AND IMPROVE SHIFT QUALITY. WHEN THE ADAPTIVE STRATEGY IS RESET, THE COMPUTER WILL BEGIN A RE-LEARNING PROCESS. THIS RE-LEARNING PROCESS MAY RESULT IN FIRMER THAN NORMAL UPSHIFTS AND DOWNSHIFTS FOR SEVERAL DAYS.
The Calibration Update Contains Improvement Actions And Enhancements To Address The Following:
False DTC P0181 (fuel temperature sensor A circuit range/performance)
Previously Released - Calibration Content
Included in IDS software release 74.03 and higher contained improvement actions and enhancements to address the following:

VSOUT signal inoperable from customer access circuits under dash
DTC P2463 or P246C (DPF restriction) and DTC P2459 (DPF regeneration frequency) - adds increased ability to perform manual regeneration at higher load values when performing system diagnostics
Calibration Content - Vehicles Built On Or Before 08/23/2010
False DTC P132B (turbocharger/supercharger boost control A performance)
False DTC P0299 (turbocharger/supercharger A under-boost condition)
False DTC P050E (cold start engine exhaust temperature too low)
False DTC P06EA (NOX sensor processor performance (bank 1, sensor 1)
DTC P249C (SCR time to closed loop) - improved diagnostics and reporting

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!
