Hello everyone,

I chimed in on this thread early on and just kind of took a back seat to see where it went. Can't believe all the disappointment and ongoing issues with the CEL misfire codes. My 2015 ST threw another misfire P0316 code just a few days ago so I took it in for service at my usual stellar dealership today. I figured I would let everyone know the results even though it basically just confirms what everyone else is hearing, "Engineering is working on it".

First a small summary of my misfire CEL occurrences. The first few around 4K-6K miles and the dealership did full diagnostics and cleared the codes along with reprogramming the Misfire Profile and KAM clear procedure (took over an hour) that seemed to help for a little while. Sure enough a few thousand miles later another code. This time I just ran it for a few days and even hit full boost just to see if anything would break lol .. nothing did but it cleared the code and CEL light went off by itself. I believe this happened 2 or 3 times so that's a total of 5 codes in the first 15k miles. Then around 20K miles another CEL so I planned to take it in again just to get it documented and see if they had any fixes, especially after reading here about all the ongoing concerns. So the next day when I took it into the dealer to look at the CEL and do the oil change the CEL disappeared on the way there. I reported it to them and as a courtesy they went ahead and hooked it up to the computer to look for any error codes. The technician came back puzzled and said nothing was stored and no evidence a CEL code was ever there. I was like oh well I'll bring it in next time when it comes on, since I knew it would sooner or later. I guess it's good news that the CEL and code goes away after a few days. I would rather have a fix though.

So today when I brought it in the CEL was still on and the service advisor was very familiar with the issue on Focus ST's. BTW I'm currently just about 24K miles. He also mentioned it affects some Mustangs too. He looked it up on OASIS and found no updates on the issue. He was cool enough to let me read the OASIS report and even gave me print out. I'll type out word for word what the OASIS report said here:

45788 Some Vehicles Could Exhibit Misfire Codes After Certain Repairs - Multiple Vehicle Lines
Some vehicles equipped with On Board Diagnostics (OBD) misfire monitor neutral profile learning capabilities may experience the MIL illuminating or flashing, accompanied by one or more engine misfire related codes(PO30x). These faults can be a result of the crankshaft position sensor profile (MR_LRN) not being relearned after engine transmission repairs. The MP_LRN data is no longer cleared with a battery disconnect. In order to properly reset the Misfire Profile, a KAM clear must be performed. Repairs that can require relearning the MP_LRN data with IDS include: crank sensor, trigger wheel, engine timing, and any time the engine or transmission (including DPS6) is removed. From the IDS toolbox select "Powertrain", "Service Functions", then "Misfire Monitor Neutral Profile Correction" and follow the on screen prompts.
EFFECTIVE DATE: 29-APRIL-2016

So this was the latest OASIS info and obviously does not explain why SO MANY vehicles have had this trouble without any of the named repairs. Especially the ones that constantly fail or fail very frequently. I feel lucky mine is only every few thousand miles and the CEL and code clears itself after a few days. The most recent code happened at start up when I noticed some abnormal shaking from the engine right after I hit the start button. I didn't notice the CEl appear until the next time I started the engine. Other times they occurred at low rpm's in in first or second gear, and all of them occurred when engine was cold.

The previous OASIS was not very helpful or encouraging but the advisor assured my Ford engineering is working on a fix. I asked him to have the tech's take a look at it after my oil change and just clear the code. Mostly I wanted to document the CEL so "just in case" I have record of it. He came back after some time and asked if I thought the CEL resulted in any drivability concerns. I told him "No" but it is annoying. He agreed and said the tech would just clear the code so I could get on my way without any delay. Sure they could of reprogrammed the Misfire Profile again but that didn't fix it last time so I guess it's best not to waste any more time with that procedure. I was just happy to back into my car and get on with my day lol.

Here is where I have some further news. The technician that cleared the code, and who is a friend of mine, approached me with some further information. He also assured me that Ford engineering is working on a solution and to be patient and one will hopefully come. When it does I'm sure there will be a long line of repairs and I'll be in that line lol .. anyway here is a word for word copy of what the tech gave me:

45856 2015-2016 Focus ST May illuminate the Malfunction Indicator Lamp (MIL) With Misfire Codes
Some 2015-2016 Focus ST vehicles may exhibit MIL On with a perceived misfire after cold start. Diagnostic Trouble codes may include P0300, P0301, P0302, P0303, P0304, and P03016. Engineering is currently investigating this concern. Refer to Workshop Manual (WSM) Section, 303-01 for normal diagnostics. For drivability concerns Refer to Powertrain Control/Emissions Diagnostics (PC/ED) manual. To assist with the investigation use the Report A Vehicle Concern link at the bottom of the OASIS report and submit a Global Concern Report (GCR). Continue to monitor OASIS for updates.

So that's my update for the topic. It's sad such a great car can have these issues on a widespread basis but at least since it has been such an issue there is hope that Ford engineers will find a solution. C'mon Ford get it done please. I love my ST and looking forward to getting some good years and another 100K miles before I trade up to the RS!

I just skimmed through most of this thread, slightly concerned as well. My 2015 ST threw a misfire code at 3600 miles during a cold startup, seemed to drive normally. I drove it straight to the dealer, ended up diagnosing it as bad #2 coil. They replaced the coil and I haven't had any issues up until recently. Earlier this week, I started the ST up to leave work and it immediately threw a CEL. Started to drive home and it was obvious a misfire condition. Rough idle, almost died twice while idling at a stop light. Vibration at 1500 rpm and could tell there was some loss of power while driving on the freeway. It has been at the dealer for three days with no update. The vehicle is bone stock with only 11,000 miles.

Noah, thanks for the update on your car.

Back on May 27th, Slow95Cobra posted a photo of that exact "engineering is working on it" update in Ford's system. It's the first post on page 43 of this thread:

http://www.focusst.org/forum/focus-...1024-check-engine-light-code-says-misfire-can-t-get-service-43.html#post1080027

So it's been almost 4 months since they officially recognized this issue as being at least somewhat wide spread. I'm taking my car in tomorrow to have the cylinder head replaced even though everyone in this thread knows that a cylinder head replacement will not solve this issue.

Either Ford still doesn't know the real root cause of this misfire issue (doubtful) or they do know the root cause but there's something about it that is keeping them from actually fixing our cars.

- Ford has many cases of this problem being reported to them
- Ford has extensive data mined from my car which captured this problem happening repeatedly
- According to people I've talked to, Ford possesses an affected car that is being / has been examined

If anyone with a pulse is actually working on this issue, they must know the cause by now.

An update on my car, I completed a lemon buy back in July after visiting service a total of 7 times in less than 1 year/15k miles. Symptoms were getting worse and continued after a head replacement.

Sorry to hear that. Are you replacing it with another ST?

I got my car back today. Replaced a spark plug and coil assembly, didn't specify which one. This would be the second coil replaced in less than a year.

Hello AK2112,

Got it, yes I figured this was not any new news. My fault for not reading through the entire thread as it has grown so large. Thanks for the reply and further details on the investigation. Man you would think something would of been released by now. Hopefully something comes soon. Ridiculous this issue does not have a solution yet. Surely Ford knows something by now as you mentioned. Good luck with yours and everyone else trying to resolve this.

Update on my 4th CEL, 2015 with 32500 miles. Ford gave it back to me with the CEL on still and asked me to just call in periodically to see if there's a fix. They think it'll just be a firmware update. Sunday the CEL went off since there wasn't anything causing the code after a few engine cycles, so guess that's a plus.

That's a big negative. I understand these things happen but the attitudes I dealt with at Ford at the regional and up level soured my view on Ford.

 

[AK2112]

Update-

I brought my car in on Monday so they could needlessly replace the cylinder head. I called them today to see if it was nearly done.

Nope.

I got some bull**** story about how Ford wanted them to do more testing on my car (get the **** out of here) and attempt a fix (which they refused to tell me what that attempt was) that did not end up fixing my car. I won't be getting the car back until Wednesday at the latest now due to this dealer screwing with my car instead of just installing the new head.

Ridiculous. More screwing around, more time without my car and more money wasted on a repair that the car doesn't need.


Also, I received my buy-back paperwork Fed-Ex'd from Ford today. Based on all my dealings with Ford up until this point, I am not confident that this buy-back will go as it should. Time will tell.

Sure sounds like they're giving you a bunch of sh*t! Hope your buyback goes through a whole lot better than the rest. Not looking forward to dealing with Ford, should I have issues with mine. But then again, I knew the risks going in.

Havent visited this thread in a while... Ford has my buyback check and im just waiting to make the exchange for my misfire affected '15 ST1... Im stuck between getting a 16 ST2 or a 2017 GTI Sport

Given all the BS Ford gave you, I'd look at the VW. But I understand the turbo lag at low speeds on those suck. Hope I have better luck with my ST.

I received the dreaded P0301 cel light today, car is a 15 with 16,000 miles. FML.

Update

Went to my dealership to do two things today.

1- check on the status of my car's cylinder head replacement (was told it should be done today)

2- speak to someone regarding my buyback per the directions on the buyback paperwork

what happened?

The dealer ended up calling the police on me and I have a video of their service manage losing his mind screaming at me for checking on my car so often.

Shal I post the video?

Two police arrived. The service manager explained what happened and then I stepped outside with the police to discuss my side of things.

As expected, the police were professional and managed to cool the whole bizarre, unbelievable situation down.

Prior to their arrival, the service manager was literally SCREAMING at me that they weren't going to finish my car (they still need to replace the timing chain tensioner and are waiting on the part to arrive)... they were just going to put it all back together and give it to me, unfinished.

Long story short- apparently I'm banned from ever going to Fair Oaks Ford in Naperville Illinois ever again. If I set foot in there (to pick up my car, to return the loaner, to buy a car, anything), I'll be arrested for trespassing.

This is all really good stuff.

 

[Redline727]

How are you supposed to get your car then?

Video please haha

 

[HBGeek]

What the actual F? Please post the video if you feel comfortable doing so. I am not sure if @FordService can help or buy reporting this guy. He sounds like a royal jackass. I also would like to know how the heck you are supposed to get your car back.

 

[AK2112]

Well, this service manager (and another service writer there) both told me that they were going to put my car back together and give it to me right there and then because I was so desperate to drive my car.

In fact, I have him on video saying they're just going to put my car back together and give it to me so I can get out of there.

Obviously this is terrifying... putting together an unfinished engine bay. And the prospect of these guys doing something to my car now that they're upset with me is also a very real thing that I'm scared of.

Once the police were there, they got Fair Oaks Ford to agree to the following:

1- They're going to finish the cylinder head repair. The timing chain tensioner will be there later today/tomorrow and the car should be finished by Friday.

2- They're going to deliver the finished car to my house at which point, they will take back the loaner.


Now, if you're anything like me- the prospect of one of these guys driving my car is also quite frankly- not appealing at all. God knows what these maniacs are going to do.

 

[HBGeek]

That is insane. Now if/when something else goes wrong with the car you will have to go to a different dealer? I would try to complete to buy back. You have spent far too much time and patience on that car.
