First off let me say I am new to the forum... and not that knowledgeable about engines.

I am unhappy with my new Ecoboost Lariat.. it has 2900 miles on it. I've had some weird issues and have been back to the dealer but they tell me everything is okay. I'm wondering if anyone else has had similar concerns or if this is just the normal behavior of the truck. I had a 2007 Lariat with the 5.4 that was smooth as glass and never had any issues.

1. Rough 1-2 shifts.
This has been a real problem spot. The shifts are rough when cold and sometimes when warm. 1-2 often gives you a kick... but the problem is intermittent. Things were bad enough on I-95 in stop and go traffic a few weeks ago that I just locked the truck into first gear with manual. The shifts tend to be rougher under light throttle inputs but that's not always the case.

2. Weird surge feeling when stopping.
When coming to a complete stop, the truck seems to have trouble getting the motor out. I feel like I'm braking through the engine. At about 1000 rpm, the tach bounces a little bit by a few hundred RPM once or twice. Only when you're finally at a complete stop does the engine return to idle.

3. Fast idle when cold.
Upon start up.. and for the first few miles.. the idle is exceedingly fast. It's annoying when pulling out of a lot and stopping. You really have to brake hard to hold it back.

4. Holding throttle in when off the pedal.
Say you're in a parking lot hunting for a space. You completely take your foot off the gas.. but the truck hangs onto the throttle at say 900 or 1000 and takes you on a trip without your foot being anywhere near the pedal.

5. Tach bounce at idle.
There's a fluctuation in the tach at idle.

Let me say that I am thrilled with the engine at speed.. it has enough power to launch you and everything else into next week. I seriously dislike the truck at low speeds and feel it needed more time on the proving grounds. If anybody else has had similar/issues concerns I'd love to know about them and what the dealer did or didn't do.

Thanks.

Problem #1: May be your Transmission need to be reprogrammed. I don't have this problem with mine as long as I'm smooth on the Gas Pedal. Because if I'm in 3rd and bounce on the pedal it will definitely kick in 2nd. But this is because you have a "no turbo spooling" situation and then bounce on the Pedal the boost will reach is maximum to give you as much torque as possible. Any Turbo Car will react the same way when equipped with a "no Turbo Lag mechanism". Be smooth on the pedal learn your truck and you'll be fine.

Problem #2: Sponge feeling on Pedal don't have this problem neither. BUT I've notice the RPM is bouncing when stoping and this is because the truck is Downshifting, well this is what I notice on my side. But no Sponge feeling. Maybe there's some air in the system...?

Problem #3: Fast Idle when cold I don't think there's anything wrong with this... this is just normal the engine will run little higher in RPM to reach the normal temperature (operational temp) faster. You will also notice (not sure on the F150 but on most Automatic Car), the last gear will not engage untill the normal temp is reach.

Problem #4: Not sure where's the problem there, this is just normal! If you want to stay without pushing the Brake you have to put in Neutral or Park!!!!

Problem #5: Fluctuation at Idle is something normal if your A/C is running. Turn off your Heating completly (push the off button) wait for the engine to reach the normal temp and you should not have this "Problem".... Note that even if your A/C light is turned off if you put the control in Defrost mode the A/C is running to help the Defrost.

Hope this help you... so far the only "problems" I can see it's the Transmission "maybe" and the Sponge Brake Pedal.

Yes, there seems to an issue with the ecoboost. Not that a dealer will admit to it. I have similar issues with my 2011 F150. Seems to have a slight miss in the engine intermittently, trans acts like it shutters intermittently under towing/loaded condition. Took vehicle to dealer and the report was that nothing is wrong. They test drove a new F150 right off the lot, and it had the same symptoms. The dealer said that there are a lot of systems working at one time. Engine control, trans shifting and trans braking (down shifting), turbo management, and it seems that some times they will conflict with each other. But that is normal or at least until Ford recognizes there is an issue. Well daaaah, of corse all of the systems work at the same time, the vehicle is running. If one of the systems doesn't operate, then the truck wont run. So all I have for you is that wait until Ford looks into these issues, but that won't happen until 30% of buyers make serious complaints. Keep going back to the dealer and develop a history record of the issues. After all it's still under warranty.

Had my EB for about a month now with 2000 miles on it. I am also experiencing issues 1,2,4 & 5.

I also am noting the issues numbered 1,2,4 & 5. However, I would add that all of these 4 issues are so minor that I have to be paying attention closely to notice them. The truck seems to always skip 2nd when shifting down as I coast to a light, which sometimes results in a "bump" when the truck shifts to first.

New to this forum and am experiencing 2,3,4 &5 as well on my 2011 Supercrew Lariat with 6000 miles. In addition I have noticed that when I am in 6 th gear and going up a grade I experience a subtle missing. Not severe like a bad plug, but a missing never the less. In addition my gas mileage has declined over the past month as well. Went in for an oil change and asked my service manager and he said Ford is aware of the problem and the complaints and there are a couple on theories and one is a bunch of bad coils on the number 3&5 cylinders. He advised I hold on for a few weeks until Ford comes up with a fix. I am really disappointed as I bought the vehicle with hesitation about potential problems with a new engine, but fell for Fords advertising regarding all the testing they had done.

[4506dave]

Mine has the long box shudder between 0 and 15km/h which Ford cant fix even after the TSB was done. Also has the slight miss/lugging in sixth under load. Month ago I put the hammer down and it missed bad, almost as if half the cylinders weren't firing, engine light came on and started flashing. Drove to the dealer right away, 2 mins away, as I pull into the lot the light goes out. Put the scanner on it and said 5 and 6 spark plug and coils need to be replaced and parts weren't available yet. Took for a test drive and could not duplicate. long story short truck goes in on the 21 of Nov to have the parts changed. 6500 km on it. Milage with this truck isn't as good as advertised, averaging 15mpg on the hiway at roughly 75 mph. But its a lot better (over double) than the 2011 F350 Diesel that this truck replaced. Overall this truck isn't nothing special and I almost always prefer driving my 2003 Dodge dually diesel with 881000 kms on it, Its get better milage as well. This is my 3rd Ford in as many years, 2009 F350 Harley Davidson, 2011 F350 Lariat, and will probably be my last.

I have a 2011 and it ran great until about 9000 miles then it started with the slight miss under load in 6th gear and also a couple of times when I would try to pass it would just fall on its face and miss and shutter I had to get out of the throttle and step in it again to get to respond. Never had a check engine light ever. Took to the ford dealer they scanned and ordered a couple of plugs took it back and left there same thing. I put a lot of miles on so the miss is a bother to me. I called the service mgr and he called Ford and they did admit they have seen some problems and gave him a list of parts to order which was coil packs for bank 2 and they had to check some grounds got the truck back to them at 12000 miles they had for a day. I picked it up and 10 miles down the road same thing. I called the dealer back and they said there is no more they could do Ford Enginerring is working on the problem. I took the truck back and made the service mgr take a ride with me and he could not believe what it was doing I told him I was leaving the truck until it was fixed because the problem was getting worse. Well long story longer the truck has been at the dealer for 3 weeks with all kinds of test being done and last week Ford had them order 3 new injectors and a new harness for bank 2 the dealer installed and same problem. They are telling me now that they are having engineering come up and take a look at the truck. So I guess if they figure out my truck they will have the fix but I could not deal with the missing anymore. With all that said I love the engine and the power. I was getting a consistent 18.7 MPG avg and 19.5 if you keep under 70.

[2011f150man]

I'm putting my 2011 Ecoboost F150 in the shop tomorrow for the sixth gear miss issue. I'm sure they will work out a fix for this issue.. Hopefully sooner then later!

[Dieselman1971]

Good luck everyone... My truck has been at the dealer for 31 days today. Ford told the dealer that know about the problem and hope to have a fix in begining to mid 2012 and to bring back the loaner and to drive the truck because the are no saftey concurns with the truck. I said HELLO the reason it has been in the 4 times is it falls on its face when you pass and twice it stumbled and would not go trying to cross a intersection with traffic coming. I told the service mgr would you or the engineer that told you to drive it put you family in a vehicle that was doing this?? He said he is going back to Ford and seek a better solution. I told them buy it back.. Now I am starting to wonder the long term issues with this engine.

[2011f150man]

I picked the truck up tonight from the dealership and they said they couldn't get a code for the issue. So till it throws a light there is nothing they can do.. go figure!

[pbyrd78]

Holy Moly, am I glad I switched to this F150 Ecoboost forum to see if anyone experienced my subtle engine problems! I have a 2010 Ecoboost MKS, and took delivery VERY early - August 2009. It's one of the first Ecoboosts out of the factory. I have 34000 on it now, 2.3 years later. For the first year, it ran like a CHAMP - all the time. 20 MPG to work, 25+ on the highway. Fast as lightening. But at about 12000 I started feeling a VERY faint missing with the cruise on heading up a slight hill at highway speeds in sixth. Mileage dropped almost imperceptably, but it did drop (I track every tank). Took it in, and because there were no codes, there was no problem Lincoln could fix. Kept driving it. It's been getting slightly worse over time. Now, if I roll a corner in 3rd gear and give it about 1/4 or 1/3 throttle (so it doesn't downshift), it will pull away from the corner like a normal V6 up to about 2500 RPM, then the boost kicks in and it takes off like a rocket, like it should. Again, no engine light, no engine codes. I was thinking of getting a performance chip, or taking it to a tuner, but kept thinking that I need to get it running correctly first. So now, as I approach my 36000 warranty end, I need to get it in and record this coil problem, so I have an active complaint.

I'm going to keep tabs on this forum and wait to see when you guys say that Ford has come up with a solution to this coil issue. I had a 2000 LS V8, and it started burning up coils after about 6 years. When a coil would go bad, it would feel a lot like this...a subtle missing at low RPM when lugging. High RPM seemed to be OK.

I do feel for the Ford Engineers (and especially the service guys) trying to chase these ghosts. But the problem is there, and I'm very happy to see it so well reported by the rest of you. Please keep us posted on your progress!!

[Crshelton21]

I COMPLETELY agree with this! I have the same problem! And the Local ford dealership I bought the truck from acts like its no big deal and not worrying about. Which is
Bull! I am not happy with that dealership nor am I with Ford. I'm a long time ford fan but their customer service at the dealership is absolutely pathetic.

[Crshelton21]

And I just bought this truck 11-31-11. Barely has 1300 miles and already having these problems.

[CTBob]

OK. As I reported earlier I am experiencing terrible mileage ( about 1 mpg better than my 5.4 2004 super crew) and a misfire in 6th gear going up a modest grade. Also the surging, high idle and shuttering as I come to a stop. Now check engine light is on full time. Going in tomorrow and hopefully can get this issue resolved. Interestingly Consumer Reports rates this engine in the F150 as recommended. I'd like to have them drive mine and see what they say.

I am also having the same issues as others in the thread. I was told by the dealer as well that there are no codes. There is definitely an issue with the ecoboost and I am concerned for the safety of my family as well as myself. I am also concerned with the effects these flaws will have on the longevity of the motor and trans. I have gotten better gas mileage in tow haul mode both highway and city, I would suggest that you see if this effects your gas mileage as well. I am going to see if the dealership will get me out of this truck and into something else without having to file a lawsuit. Class Action anyone? I paid to much for this vehicle to be having these issues, which are not even being addressed.

I have about 2000 miles on mine and I love it. Went from an f250 crew cab diesel that I loved but was tired of the extra money for diesel. Cost half as much in fuel to run this thing. Runs like a scalded monkey and I couldn't be happier with my mileage. Hard to keep your foot out of it though.

Sorry you guys are having problems. Of course we all knew this is a completely new engine. kind of a crap shoot really!

Its a shame engine 448AA pulled off the production line for the promotion videos had no issues. I'm not biting the bullet on this one. Taking it in again Monday and will most likely get the same response. This truck as of now is a lemon.

[Dalemc]

My question is are these are 2011 trucks or are they also 2012? I have been considering trading my 2009 F250 diesel in on one but have some major concerns about the engine. I also pull a 3 horse trailer at times as well as my 19 ft Ranger bass boat. I am trying to find out what kind of hit the mileage takes when pulling. It is one thing to say it will pull 11,300 pounds but concerning when they don't say what the mileage is if you do.

Thanks

Dale

well I have about 2700 miles on my truck now. A 2X4 Crew Cab with 3.55 rear end. I love this truck. Just finished a 275 mile road trip. 21 miles to the gallon burned 13 gallons by the computer and it took 13.075 to fill it up. Calculator says the computer is right.. Now that is at 75 on the interstate. At 65 on two lane blacktop the mileage is 22,5. . and average around town mileage is 18.5.

as far as the weird shifts and such, hell its a six speed transmission. Sometimes its looking for a place to go. you need to drive smoother.

Now this engine hates being cold. Idles high and fuel mileage goes to hell when its cold. Why don't you just crank it up in the morning and let it warm up like a diesel. that will solve that problem

I have learned through my years of experience dealing with people that there are those out there you can never satisfy

or maybe I just got a good one

Oh for the guy with the diesel. I traded an f250 for this truck. Cost half to feed this thing.I loved my f250 and if I wasn't sick of the extra $0.60 per gallon I would still be driving it. Now as for towing I haven't challenged it yet.. there won't be a problem with power. . hope that a weight distribution hitch really works.
