Just got off the phone with a lawyer. He is taking my lemon law case. He stated that my case is different than most he has dealt with because both Ford and my dealership are refusing to fix my truck, but acknowleging the problem. Good luck with your Facebook attempts. Maybe Ford will start to care about their customers when our problems start to cost them money.

I'm in that same boat with the attorney looking at my service invoices and seeing the statements that the dealer called Ford and noted that it is a known issue but no fix at this time. I had mine in 5 times prior to starting my lemon law... Takes awhile. The first paperwork went the first week of April and still not close to a resolution....

Higher 6th in EBs exacerbating the problem makes sense to me. Whenever mine does it the very first jerk feels like the engine lugging as in a tiny V6 not yet under boost in high gear at too freakin' low of an rpm that doesn't have the smarts to simply unlock the TC and downshift the second the load of the hill or stiffer headwind I've also noticed is detected.

Then I do feel/hear turbos/wast gates arguing if the shuddering continues.

Does this seem the same to any of you?

The answer is yes and no. It depends on the particular specifics at that point in time when the problem or problems occur.

The one time my engine bogged so heavily it had zero power, the more miles driven the worse it got (like over a period of 50 miles of hi-way); that just going up a gentle incline on a Dallas freeway at 60mph it had so little power it downshifted at steady state cruising and getting only 16MPG’s (this specific case was after 275 miles of steady state driving at just 16MPGs for the last 50-70 miles). Basically it was a joke. The engine was literally joking for lack of air. I know what hydrolock is like, and it was very close to a full hydrolock state. I cleared it in the most aggressive manner possible and it drove great for the next 650 miles.

Conversely, I will often have the poo cho waste gates flutter etc, missing etc long before the engine gets to a state of completely drowning in water. And those types of experiences occur frequently. I have been through the situation that upon entering the freeway after a short 10 minute stop I thought the front left tire had gone instantly bad………….turned out it was the dam engine shaking again. Within 2 miles of driving it was smooth as a baby’s butt again.

Now sometimes I will experience the lower speed lugging, jerking, and bucking in the power train, but this has always been after a period of steady state driving and the associated water accumulation (even if it is water from a previous day). If the water is cleared out of the CAC, and the dew point temp and ambient temp is greater than 10 degrees difference it will NEVER exhibit any of these problems – even after 700 miles of driving.

I have also had the “fall on your face” effect twice. Since this is throttle by wire system (and a poor one at that), I do not know if that was an electrical issue or a condensation issue. That has not occurred in the last 2,000 miles or so. In each case I just pushed on the accelerator to go from 40mph to 65 mph (less than an 1” push down), and nothing happened at all – “no go” and “complete silence”, just coasting. Took my foot off the accelerator and put it back on and all was perfect. Please no one has to tell me this is turbo lag (it’s not), I have driven diesels (good ones and bad ones) for 20 years.

Now many others have posted their problems with power train, transmission, driveshaft, etc. My truck really does not have any of those issues. The only time it does become ruff in the transmission is after the engine has developed its problems in that specific driving cycle. If and when the engine is running badly, then all those engine “fits” can start making the tranny act up too (though very rare in my truck).

I think the higher 6th ratio has absolutely nothing to do with anything. I can make my EB shudder in 4th, 5th and 6th at will. I have a hill I go up a couple of times a week and it's posted @ 30MPH. I go up it in 4th and it shudders just like it does in 6th @ 60 while pulling a slight grade. That little bit of a ratio change in 6th is negligible.

The reason I brought it up is because mine only does it in 6th and it is very light compared to the misfire feeling. I could understand that the misfire is caused by the condensation issue, but this rarely happens to my truck. Maybe 2 or 3 times a month. The 6th gear lugging shutter though happens every time i pull the slightest grade. It doesn't feel like the engine is missing. Its just not that intense. I could see how it is something in the TC or either the waste gates fluttering and messing with the boost.

If you take a v8 at 1200 rpm and the turbo charged v6 at 1200 rpm to the same hill at the same speed with the same gear ratio the 6 is going to feel choppier than the v8. The v8 has more cylinders less pressure per cylinder per revolution. The v6 has a lot more push per cylinder to do the same work per revolution as the v8.

Take a turbo 4, same load rpm and hill, even choppier. I'm not saying that people are not having problems with there trucks. Ford needs to man up and fix the ones with problems!!! Just saying that the Eco boost motor is not going to be super smooth going up a hill at low rpm.

i think Ford over complicated things again, i don't know why but it seems everytime Ford comes out with something new it is so complex and turns out to a disaster the 1st year or so Examples 6.0 Diesel, 6.4 diesel, ( not sure about the 6.7 diesel yet) '04 to '05 F-150 (cam phasers), 2011 Eco-boost, and the thing that pisses me off is they over hype the new stuff like it is the greatest thing ever good luck fellows

While I don't want to make light of the situation we are all experiencing, I just want to say that Ford had the ***** to go where no other American truck maker was willing to go. The EcoBoost is a great concept and mostly a great little engine who can hang with the big boys day in and day out. While I am planning on dumping my truck very soon and I am not at all happy with the run around Ford has given it's customers, I will probably happily by another EcoBoost F150 once they get the problems fixed.
