How long has this been happening?

It's been going on for a couple of weeks.

Try getting a tune

But seriously, the title of this thread is totally uncalled for. I just passed 5,000 miles which were mostly driven in below freezing temps without any issues whatsoever and I push it pretty hard. This is probably an issue that will effect less than 1% of the ppl who buy this car

Is your car still at Advantage Ford or did you take it back from the dealer?

Kind of funny (in some sad way) that we both got ours from the same dealership and have the same problem. It's cursed!

 

[spdracer50]

yes it sucks. However they are working on a solution and it doesn't harm the vehicle and sounds like it goes away once warm. Again it sucks but they will find a fix quickly I'am sure. I've not had any issues at all and I don't baby it by any means ive got over 4000 miles now. Good luck hope they find a fix quickly.

So.... They acknowledge there is an issue, the issue will not cause any damage, and they state they are working on finding a solution.

Sounds to me they are doing exactly what they should be doing. What else would you expect them to do?

Let me get this straight. So just because you're having issues that they are having a hard time fixing you post this telling people to not to buy the ecoboost... really?!?! Like seriously. I'm gonna go trade up for a GT now just because you said we shouldn't get the ecoboost.... makes sense right?

Couple questions. Did the techs try changing spark plugs, coil packs, check for loose wires or hoses, vacuum leaks, instead of changing octane gas did they change brand, etc? Sometimes it's stupid little shit that will cause a modern internal combustion engine to act funny.

I'm not sure. But I think you bought the first time a new car what is also a brand new model. Our Grand Cherokee has his 8 recall. Couple times we got a letter saying the same you are posting: "We are working on a solution. .....Please monitor it closely."
Don't buy a EcoBoost?? What about the burned out GT? Don't buy a GT too? Honestly?

1.) I expected some backlash from the title but, here's why I sent out the warning.

I was told by the service advisor today that Ford was aware of the issue and sent the cars out anyway in hopes of fixing the issue later. That means that there could be other issue's Ford knows about like the white smoke issue another user is having on this form and is also unable to resolve but, Ford will continue to sell the ecoboosts anyway.

It's just fair warning. "The Ecoboosts seem to be the most problematic right now." A direct quote from Ford Service.

2.) The statement that "it's not causing any damage" is not true. Error codes don't just appear out of thin air, there has to be an issue for it to appear. After speaking with another tech and reporting that the engine seems to be running ruffer now after they messed with it, leads him to believe there is damage being caused. The issue is they can't isolate the source of the problem.

You can buy a code scanner for $70. You can see the codes, delete the codes, see them return. A scanner is a good tool to have and cheap. U
It works on all modern cars after a certain year ( I forget exactly).!

Or a bluetooth OBD2 scanner and the Torque app on your phone. About $25 that way.

I agree with you davekro, it's a great tool to have in your case.

I need to chime in here as I have this same problem and my thread is a few below this one. I have currently 305 miles on my Ecoboost that I got last week and I also have the check engine light.

I believe I bought it at the same dealership that spdracer50 got his from. What a coincidence lol

Ok so I think first, there are GTs with this same problem that I've seen so it's not the ecoboost engine that's a problem. I don't know what the guy with the GT did to fix his but it was back in november and he hasn't responded to my PM.

Secondly, I haven't had the chance to troubleshoot it with a dealership and I have been corresponding with user "FordService" on here hoping to find a dealership take a look at mine. Looks like so far, Ford is stumped as to why this is happening? Spdracer50 is a few steps ahead in terms of troubleshooting than I am. I haven't taken mine in yet.

Mine doesn't run rough at all though, it runs normal I guess. I can't tell if there's any power loss or anything since I never got to go WOT due to the break-in period. but as far as starting cold, I don't have any issues.

My code is P0300 which is "random misfire" and not specific to a cylinder. I tried using better gas and I have a code reader and cleared the code. The code went away and came back after 80-100 miles.

DURING the time when it was gone, around 75 miles or so, I ran the code reader again. Since there was no check engine light I figured i'd try it anyway. There was no trouble code BUT, the EVAP monitor was not ready. It was still completing its drive cycle. So I am assuming that once the EVAP monitor became ready, that is when the dash showed a CEL. Given the fact that there are GTs with this problem and it is not limited to Ecoboosts, my uneducated guess here is that it has to do with an EVAP or emissions issue and not the engine.

Just throwing it out there. I don't know how to proceed now since if Ford is saying to wait on the fix and they're working on it, should I even bother bringing it into the dealership? I don't want them to mess with the car and hold it for weeks, it's my daily driver.

EDIT: Spdracer50, can you send this to whoever is that Ford that you are talking to? http://www.mustang6g.com/forums/showpost.php?p=370444&postcount=30
He said he fixed it and I also had an inkling it was EVAP related. Maybe they can check that.


EDIT2: Dude with a GT that had the same problem and code P0300. Hasn't responded to my PM.. :( Hasnt been active since Dec so I dn't know if he fixed it or if he sold the car or what.

Thanks for the info. I would reccommend that you defently take it in even if they can't resolve the issue just to get it on the record.

I picked up my car today. Don't take it to Advatage Ford, they have really bad service and I don't think the techs know what they are doing. Take it to a larger dealership like Ken Grody or Galpin Ford. That's my next step.

If you check out my other thread it has all the details.

I will forward it but, I was told that the GT's problem is completely different than the Ecoboosts. It seems like they have already resolved the GT's CEL issue. It was problem with the spark plugs from what I was told. Our issue is completely different according to Ford Service. Please let me know what happens if you take your car in.

Just because there's a cell doesn't mean your engines being damaged. Also aren't the smoke issues with aftermarket downpipes? You can search for days with just about every manufacture with aftermarket downpipe having that.
The sky is not falling, relax a little.

The statement that "it's not causing any damage" is not true.

This comment alone shows you are not knowledgeable enough to be making any conclusions about the status of your car. Let the dealership and Ford do their work. Take a Xanax and chill the f out.

I agree the sky is not falling but, I'm sure you be a littile pissed off if someone told you your brand new car was broken and they are not going to fix it for a couple months.

Hey poops, I've got a lot of knowledgable on cars but, if you read my complete post you would see I consulted with another mechanic. Read throughly before you start criticizing.

The dealership isn't doing anything more about it. They told me to wait a couple months till Ford feels like fixing it.

Wow that is crazy, I hope you can get your car fixed, I would be pissed to say the least.

Better change the title thoughopcorn:

Damn okay. Yeah I think I'm going to try a bigger dealership. Ken Grody has shit reviews but you never know if it's someone bitching about bad service or bad sales. Pretty much the biggest dealership around here though so I'll see what FordService has to say and I'll get the process going. Kind of sucks to deal with this.

Did they at least give you a rental for the week your car was gone?

 

[midnite9150]

oh yeah forgot the should of bought a v8 comment,there now thats out of the way carry on.

as if a V8 has never had first model year teething problems. Oh wait nearly every generation of modular did! especially the coyote had plenty of cylinder failure issues in its first year.

I bought the ESP plus rental coverage luckily before the CEL came up so they gave me a loner while it was at the dealer. Best of luck! Maybe we can get them to issue a mandatory recall or find a fix faster.

Still not sure why they'd drain the tank and fill it with 87.I would understand draining and filling with higher octane but lower?

Is your car still at Advantage Ford or did you take it back from the dealer?

Kind of funny (in some sad way) that we both got ours from the same dealership and have the same problem. It's cursed!

The dealer probably changed out the gas because maybe they thought it got some bad gas. Maybe the dealer has their own gas storage tank, and it's contaminated. I agree, there is no way 91 octane is going to cause an issue like this.
