Surrendered my CEL affected '15 and got my new 16 st2 last week.. fresh off the truck with 6 miles on it with a healthy discount off msrp. I like this car a lot, sync3 is worth it and looking forward to the software update to allow Android Auto.

I decided to roll the dice and see if I got one from the good batch, if not ill just do another buyback :sweat_smile::yum:

 

How bad was it/what did you have to do for the buyback? Between the seat shenanigans, the engine issues, and now a recurring U3000 in the APIM with random/horrible sync issues I am getting the feeling this is in my future...

 

You can add me to the list! 15 Focus st with around 15,000 miles and a p0303 code. Taking it to the dealer tomorrow to see what they can do.

 

Let us know what they say/do

 

2015 with 44,000 miles. Stock besides wheels. Car has been flawless until now. Got a cel and rough idle last week.

Lately the cold start idle had been getting rough. Its been shaking more and you can hear the engine missing. Last week the CEL popped on and the cold start idle had gotten really bad. I could barely get out of the parking lot at work without stalling. After warmup everything is fine. MPG and power all stayed the same. So dropped it off at the dealer overnight so they can replicate symptoms in the morning. Got the car back today. I had codes 303 and 316 with misfire in #3 cylinder. They said my car needed an update/reprogramming of some sort so they did that, reset the memory and cel. Car is driving great again, even after warmup it is much smoother coasting in gear and also sitting at redlights. The service advisor told me they have been getting lots of ecoboost cars in with CELs lately, and that Ford engineering was investigating and at this time no fix is available.

 

The exact same thing has happened to most of us. Keep your eyes peeled because the issue is likely not resolved.

Can't tell you guys how excited I am to be in the misfire club too!! 15 ST3 with 13k on the clock now.

Dropped mine off at the dealer again this morning. This makes the 4th inpatient visit for my car. I'm having the same same misfire code and symptoms as all you guys: misfire on cold start up at idle. They've thrown plugs and coils at it. Reset (and sometimes the say "reprogrammed") the ECU about 5 times. Letting the process happen naturally, I guess. Glad its covered and glad for the rentals/loaners. Had a couple ecoboost Escapes and a F 150 ecoboost for loaners. No misfires in those yet.

Funny thing, the car threw a code once very early on, about 4k miles. Went away, and did not reappear for over a year later, until late October, 2016. Its back with a vengeance now. I didn't even think to put my BOV back to stock before taking it in to the dealer. They haven't said anything yet about it. I have a Cobb catback, which all the service people love. They compliment me on it every time.

 

I got my status call from my service manager this afternoon, and his tone was very deflated. He was sad to report that they had not figured out the source of the problem, and it would be another day before I heard back. I told him about this thread, and he was super interested. He even asked me to email him the link, so he could read some of what I told him about on the phone. If he ever gets to page 83, "Hi Todd!"

Here's to hoping that all you FocusST.org people do, by keeping fellow ST members up to date on what is going on in your world, will ultimately help!

In the meantime, I'm enjoying my rental AWD Ecoboost Escape. not.

 

Today's update: Surprise!! They can't find the source of the misfire.

Going to have a look with a borescope, and see if there are any valve train issues, carbon, etc.

Any wagers on whether this test will yield an answer??

 

I don't think they'll find anything.

But I give it legit 50/50 odds that they move to replace your cylinder head.

 

Hello Everyone!
I skimmed through this very long thread so I didn't know if anyone already posted this information.
I just purchased a 2016 Focus St last week and I was driving home yesterday, my CEL came on. I took it into the Ford dealership and the tech told me that this is an on going issue which Ford has been researching it since May 27th 2016. He told me that as of right now, they don't know what is the root cause of the issue and they will contact me when they do. He gave me this print out.

Thanks! I emailed this to my service guy today. No update from them yet. I hope they decide to forego tearing the head off for now.

Is there any indication whether this more likely an electrical/software issue versus a mechanical problem?

 

Not sure if my issue is similar or relevant... but I went out to my ST today to head to work and as soon as I turned the car on, the RPM's dropped to about 1k or less. 99% of the time I wait for the RPMs to drop as it does it's little warm up session. But it instantly went to 1k RPMs. Had the Service Engine Fault message pop up but no CEL. Turned the ST off and then back on. Same thing. 1k RPMs instantly and same message along with the CEL now. I pressed slightly on the accelerator and the car started to shudder and vibrate almost like it was misfiring or something. It seriously worried me so I turned it off and took a different car to work. Has anyone had this issue before? I'm getting tired of having to take this thing to the dealer and I'm worried about having to call a tow truck to get it there as I don't feel comfortable driving it on the highway.

 

was gonna get a stratified tune but then started thinking... is it even worth getting a tune knowing that this thread exists? what do you guys think?

 

It probably depends on what the fix for this problem is, and whether a tune could be reasonably blamed for causing the condition. There is a pretty good record here of cars that developed the condition without a tune at all, but I probably wouldn't risk it until the final solution comes out to this problem.

Given that this problem could be a software issue (if it is the same as the EB Mustangs) then maybe a tune could prevent this altogether? Are there any stories of cars who had the misfire MIL pop up, and the issue went away after flashing a tune?

 

Crazy.... I just popped on here to look into my cylinder 3 misfire that I've been getting... Ridiculous. I've got 3700 miles and popped two CEL's for misfires in the last week.


EDIT: actually, I'm an idiot... its a knock sensor P0332.... For some reason I have cylinder misfire stuck in my head.

 

I'm frustrated to come back to this topic 20 pages later to find that Ford hasn't come up with a solution yet.

What really concerns me is that I live in a place where customer service is still taking baby steps (Doha, Qatar). I finally took my ST to have the issue checked knowing that they would not be aware with "any issues related to this model" and that the problem would not be solved. They said the problem was a dirty throttle body, saying that it's normal in the region because of the dust and sand, and gave the car back to me with the same issue: unstable idle when starting the engine when it's warm. Also, gears are not good, it's hard to stick it to 3rd sometimes, almost like something is out of sync when I try to put a gear in.

I talked to one of the techs there and he is unaware of any TSB for the Ford Focus and he was sure that the problem was the throttle body... In other words, this process will be long and painful, as there's no such thing as a lemon law in Qatar. We barely have customer service...

I really don't know what to do and, sadly, I don't want this car anymore. Sadly, because I love it. It's been one year since I got it, I drove only 5000km and I can't do anything with it so I don't lose warranty...

This sucks.

 

Another one to add to the list. 2015 focus st, 8000 miles, check engine for misfire after starting car from sitting all day at work. Will keep you posted.

 

I hope Ford actually does put out a fix for this. I'm sure they know what it is, but likely will cost them big $$$ to fix. My guess is that due to the fact that the ST doesn't constitute a huge number of sales in the pantheon of Ford Motor Co., the beancounters will continue to tell dealerships to keep "swatting flies" until everyones warranties are up. Sorry to be such a pessimist, but I'm loosing faith in 'ol Ford on this one. Can't wait until mine starts acting up. :furious:

 

Add another 15 ST3, bone stock, to the list. Just under 15k miles. First code thrown about two weeks ago at cold start when leaving work, cylinder 3 misfire. Dealer cleared it and updated the software. Second code thrown yesterday, cold start, leaving work. Car is running rough at this point. Cylinder 3 misfire. Dealer swapped cylinder 3 ignition coil, did not resolve issue.

After reading all 84 pages of this thread today, I'm about as far from optimistic as one can be.

@FordService at this point I doubt I will ever feel safe driving this 2015 Focus ST which is so poorly understood by Ford itself. When will Ford do the right thing and allow consumers to exchange this vehicle, which Ford has apparently brought to market prematurely, for a full refund of their deposit and monthly payments? I prefer to work with the manufacturer before pursuing less amicable avenues and look forward to your response.

 

More and more misfires huh. Crazy.

Just so everyone knows, At fordservice, which is the CRC (customer relationship center) is a service that is third party and is hired by Ford. When you contact them, you are not contacting Ford Corporate. People from Corporate can read what the CRC documents but the CRC can only do what customer service entities do. Do whatever is within their power (which is limited) to make the customer happy. This can include organizing rentals, creating service appointments and in some cases pay full or in part service bills for non warranty stuff.

And, maybe I am wrong but I was under the impression that the original issue with the misfire code was that there were no symptoms? You could not physically feel the misfire. Just a CEL and a code that had set at one point but was inactive when checked? Can anyone clarify for me? I ask this because it is possible for an engine to misfire and not be related to what this post originally started with. Any engine, for any manufacture can misfire. No engine on this planet is immune from misfiring.

Just a heads up for the people who feel "unsafe" (what a joke) and want to turn their ST in for another non-Ford vehicle. That car could misfire too. Or have an entire list off issues to choose from. I agree Ford needs to find a resolution to this issue but people need to stop acting like this is Ford or ST specific.

One other question, has anyone experienced the DTC with no symptoms or with symptoms and put a tune on the vehicle? If so, did the fault ever return?

I about just shy of 16K and I have been tuned for about 13K, no misfires for me.

 

@tpiechow, there are only two jokes here: Ford's (lack of a proper) response to this issue, and your defense of Ford, Ford techs, etc. Oh, it's hard to diagnose these problems. Then sell the car for more money and hire better, more qualified techs, or spend more money on engineering R&D before taking ~$24-30k from consumers per vehicle.

There are three possibilities here, none of which are good for the customer:

1. Ford is not assigning enough resources to determine the root cause of the issue.
2. Ford has assigned enough resources, but is technically incapable of statistically determining the root cause of the issue. Look at that joke of a FSE that @AK2112 got looking at his engine. Probably some fresh out of college engineering noob that doesn't even know what a SHCS is.
3. Ford is able to statistically determine the root cause of the issue, but is either unable or unwilling to face the facts (e.g. too expensive to address).

You have a lot of Ford automotive experience? Do you know what happens when a sensor supplied to Ford fails? Go read up on APQP and 8D analysis -- the supplier must implement a containment plan, identify the root cause, and define the problem resolution within 14 days of the return of the failed sensor, all while ensuring continuity of supply of the affected sensor. Fourteen days. ONE-FOUR days. Ford has had over 400 days. Futhermore, there are often financial penalties involved. Talk about a double standard.

My issue with feeling safe driving this vehicle isn't specifically about the misfire. It's about Ford's inability to solve this problem and their unwillingness to engage with their customer base and do the ethical thing to make the consumer whole. Assuming that Ford doesn't understand the problem and this isn't just a board room calculation of how expensive engaging in the legal process would be versus recalling affected vehicles (*cough* Pinto *cough*), how many other things don't they understand about this car that will show up AFTER my warranty period ends?

I appreciate most of your contributions to the thread @tpiechow, but I don't think you're viewing this through entirely unbiased eyes. FYI, my car is not symptomless, it's running rougher than a sailor's hands after a year at sea.

Edit: I agree with you that modern driving systems have become rather complicated and that offers extra challenges to the service staff. My dealer is being fantastic at this point as well (although I'm not that far into my sure-to-be-saga). I just think that Ford should, by this point, be prepared to offer consumers who purchased vehicles with this known failure mode with an exit plan which fairly compensates the consumer.

 

My cold start idle has either degraded over time or the more likely option is that I've simply taken notice of it more since experiencing all this business.

One thing I can say with legitimacy is that since having my cylinder head replaced, the idle (at all temps) has gotten significantly worse. I have not thrown a code yet but the god damn car stalled out in a drive through this past sunday night.

I don't know. I'm beyond caring at this point. It's a cheap, poorly made car that is fun to drive and Ford service is offensively awful and truly pathetic. They're terrible on so many levels, well beyond the stuff we have dealt with in this thread.

The service experience alone is enough to make me recommend friends avoid buying a new Ford.

 

To elaborate I again am getting this code as of Tuesday night leaving work. 2015 ST 2 8000 miles.

I'm more than nervous after reading all these posts that I to will have the same issues. When I called the dealer to make an appointment I mentioned the service bulletin but they will not let you say a word over the phone. I pray mine is fixed as I know it's not a exspensive exotic car but to me it is.

Again I will keep my status updated but for now my car will not be seen till 11/23. I have the service code printed and ready to bring with me. The thought of some greasy slob destroying my seats or scratching my car freaks me out beyond all hell.

agreed!

 

Update on mine. This is the end of two full weeks in the shop (it was previously in the shop for a full week, and then two short stays for a day each) - they are, and have been since last Wednesday, "waiting on Ford to tell them what to do." They reportedly got a "whole list of tests" to run, primarily focused on determining "whether there is a problem with my vacuum." This explanation is almost nonsensical. It is obvious that I am not getting the whole story anymore from the dealer. I have a strong suspicion that my car is parked in the back lot, basically forgotten, until Ford tells the techs what to do next.

Has anyone pursued their respective state's lemon law on this particular issue? Mine technically qualifies in my state. This is my car's fourth time in the shop for the same problem, which remains unresolved. My state requires only three failed attempts, or a cumulative total of 30 days in the shop. I know most of you have been dealing with this much longer than I have - and must have a far greater level of frustration. I'm over it. I will either pursue the lemon route, or go trade it on a STi.

 

When they say same problem, does that go to as generic as the check engine light being on or does it come down to the meat being the same codes?

 

after replacing all the cheap stuff that was on the engine, I hope it's more durable now.

 

Here is NV's Lemon law:

It is presumed that a reasonable number of attempts have been undertaken to conform a motor vehicle to the applicable express warranties where:
(a) The same nonconformity has been subject to repair four or more times by the manufacturer, or its agent or authorized dealer within the time the express warranty is in effect or within 1 year following the date the motor vehicle is delivered to the original buyer, whichever occurs earlier, but the nonconformity continues to exist; or

(b) The motor vehicle is out of service for repairs for a cumulative total of 30 or more calendar days within the time the express warranty is in effect or within 1 year following the date the motor vehicle is delivered to the original buyer, whichever occurs earlier, except that if the necessary repairs cannot be made for reasons which are beyond the control of the manufacturer or its agent or authorized dealer, the number of days required to give rise to the presumption must be appropriately extended.

again, information only. Not to be construed as legal advice.

 

Not even sure what all that is supposed to mean. I have been to the shop (dealer, went to a different dealer for most recent check) 4 times now, wonder what they consider reasonable.

 

Forgot to update earlier. I brought it in and they went ahead and replaced my coil pack and spark plug. Took two days but I was able to get my car back at the end of day 1 and bring it back in the morning of day 2. Luckily I work right around the corner from the dealership so I can drop it off before going to work and get a ride to work. Well all was good for around 600 miles but that doggone check engine light is on again so back to the dealer I go. I was so excited when I first got this car and was thinking how great it is that I have a new car and I shouldn't have any problems then this crap comes along. I'm just happy it isn't anything serious yet.

 

I got the got checked at an auto parts store and there was a p0300 code three times. It listed it as pending, confirmed, and permanent. I've seen the pending and confirmed before but not the permanent. I was just wondering if anyone has insight as to why it would list it as permanent?

 

Update on my saga: Since some of you have reached this point before me, like AK2112, it is easy to predict how my story will play out. The additional "diagnostic steps" recommended by Ford (in my pervious post) did not yield any useful information. Apparently my "vacuum" is not the problem.

Ford is shipping a cylinder head to the dealer for replacement. I objected, and indicated that this is probably a software issue. My service tech indicated that Ford would not be wasting money on all this work if it was a software issue.

I'm not sure who is the bigger fool in this situation, Ford, the dealer, or me! I have serious concerns about invasive mechanical "repairs" on my car - not the least of which is resale. I would be hesitant to buy a used car that had so much work done during the warranty period - especially when very little, if any of the repairs performed, actually fixed the problem for which repairs were necessitated.

 

Im pretty sure AK2112 said a few pages back that the car has been noticably rougher since getting a new cylinder head. The guy is right though, ford would not be paying for all that work if they didnt think it may fix something.

 

at that point @NickP I would not allow a head replacement until a reason for it is presented

 

So my car is almost done being rebuilt, I went in today to deliver the last piece needed to crank up the car.
Two weeks ago I brought in a 90 degree silicon elbow, one side 3' in diameter other side was 2.5' in diameter; costed 10.85$ or so, now he needed a port for the turbo for the bpv to blow into. My old COBB elbow was too big and had the had the port needed. I told them i'd return with a intake manifold symposer delete with port (that I brought in today) Well my mechanic forgot...and drilled into the new 10$ silicone elbow...fml...So I told him to appolxy it shut (glue it shut) It sounds like an iffy call, but I NEED the car now.
(I hope posting this here is ok)

Advice?

 

Whoa there, thats a really bad idea.

Just stick a pencil in the screw hole, call it a day.

 

I believe they'll replace it right, the mechanic assumed I was going to return with a port that fits into a silicon elbow.
