My instructions on restoring the hybrid EV function on the Ford Fusion Hybrid approaching the 8/9+ years mark.

I did the battery age reset last night and the instructions were great!  EV works like a new car now.  Thanks Allen!

For owners who did the battery modification months ago, has anybody had any issues with battery degradation?

Allen, I created an account on this site just to say THANK YOU! I had been researching this problem for 2+ years, and never found anyone that described the same problems until I recently ran across this thread. 

 

My 2010 Fusion with ~180,000 miles now instantly drives like it did when it was new. Not only does it finally use the battery again, but the annoying (and often dangerous) hesitation that occurred when pressing the go-pedal from a stop is gone. For those experiencing the problem, stop browsing the web and put down your beer and go follow Allen's instructions to fix it now!

 

I don't know what the long-term effects of this change will be, but frankly, I don't care. It's a 10-year-old car that has a decent number of miles on it that wasn't working right. I had little to lose and much to gain, so I gave it a shot, and I'm definitely glad I did. It literally runs like new. I never thought driving a 4-door sedan would put a smile on my face, but it did tonight!

 

Allen, thanks again for not only taking the time to figure this out, but also for taking the time to help all of us by documenting the fix.

Wow, this fix was amazing! Thank you so much!

 

I bought my Fusion on the last few days of December 2018, and it never drove in EV mode or in hybrid mode very often. It now has 188k on it!

 

I was perplexed, did lots of research, almost bought a new hybrid battery pack! I had the car sitting for 6 months due to rust issues making the car unsafe, but I bought my friend's water-damaged fusion hybrid (drove over a puddle) and used/new parts from that car to get mine back on the road. Now, I found your guide, made the changes and am driving trouble-free! It's been good for about a week now! This is awesome, thank you so much! I almost swapped my friend's battery from his fusion, which at 150k miles is a bit less used, but the mechanic I had never had swapped a hybrid battery, and didn't seem to have guys that really knew what they were doing. So glad this saved me hundreds from doing that and I avoided the risk of any complications with the swap.

 

Also, is there a way to manually configure the battery to go into re-conditioning mode with Forscan, or any other software that is similar? I don't want to wait for the car to re-condition itself. I also don't want to spend $700 on one of the Autel MS 808 or something similar.

No need to force reconditioning. It will probably do it on it's own at some point. Information says if reconditioning is unsuccessful a message will appear to take it to the dealer. I have not heard of any of those messages appearing to date.

Hello! I found this forum topic when Googling the 'red warning triangle' issue on my 2010 Ford Fusion Hybrid and I'm VERY happy that I did!  I ordered the Wifi OBD-2 connector and just paid for the 1 year FORScan license (10.00 US), figuring that even if it doesn't work, I'm only out 1/3 the cost of a dealer diagnosis.

 

2010 Fusion Hybrid with nearly 249,000 miles on it.

 

I followed the steps, selected '1' and disconnected, and restarted the car.  Since I live in the boonies, I took the vehicle in for a Dr. appt.; I immediately noticed that it had the 'pep' back in it from a standing start.  It had gotten to the point where it would 'drag' really slow for about 2-3 seconds from a standing start, then the motor would kick in like a normal car.  Really frustrating, Ford Motor Co.

 

I was able to get all the way into my appt. with no issues (35 miles, up to 75mph on the freeway) and this was my result.  It hasn't been in the 30's mpg for about 18 months.  I'm super stoked at this point!  Thank you to Allen84 for the instructions, and to everyone else posting on this topic! Your experiences are why I was willing to try it!

 

I forgot to mention; I have a long trip (driving) coming up, so I'll be taking this rig and will let everyone know how it goes.

Thank you allen84.  I followed your instructions on our 2010 Ford Fusion hybrid with 70K miles.  We had our mechanic disconnect both batteries last week in hopes that would reset the battery age but it didn’t.   I used Forscan and ODB device from Amazon.    I changed the value to 1.   Our FFH has been operating like new for 2 days.  It worked instantly having making the change.    Before I decided to order the ODB device on Amazon, I had called 3 Ford Service depts in my area and mentioned the OASIS report regarding our FFH.  None of them knew or heard of Ford,Mercury or Mazda hybrids from 2010-2013 having battery issues.

After months if not years of thinking my transmission, fuel injectors, spark plugs and more was wrong with my 2010 FFH, I noticed one day that EV mode was not working.  I started monitoring the EV movement on the main screen and noticed the battery was shutting off and ONLY receiving power and not expelling power.  I found this post and followed it and it worked to perfection.  Who knows how long I have been driving around on ICE only and how much money I have spent on fuel, fuel injector cleaner, spark plugs, coils, and more only to find it is a simple software bug.  The fact that Ford disables the HVB is pretty bad and makes me wonder if this is class action worthy.  How many people haven't been savvy enough to find this thread or similar and bought a new HVB or a new car or even spend hundreds on diagnostics only to be told nothing is wrong. I love Fords but this is just one more shenanigan.  

 

@Allen - Please DM me for further.

Allen Thank you so very much. My wife has a 2010 Milan Hybrid with 55,000 miles. She has been complaining about loss of pickup, and said her gas mileage had fallen to to 22MPG.  I just figured it was the cold weather combined with the auto start. I rarely drive the car, but decided that I should check into it. I reset the MPG, and she was right. I couldn't get above 22MPG. I started looking at the digital display and listening. It was obvious the Electric Motor was not turning on. My first thought was it needed a battery, and I guess we should get rid of it.

I  started to search for solutions on line. I was just getting ready to take it to the dealer when I saw your post. I bought the OBD from amazon, and I followed your instructions. It immediately corrected the problem (it's been two weeks).  I can only imagine taking it to the dealer for poor gas mileage. I probably would have bought new plugs, coils, air filter, and intake gasket only to still have the problem (if not a battery).

Again, thank you Allen. Anybody who follows your instructions and takes their time can do this. I hope that Ford will own up to this problem since many more cars will be hitting the 10 year mark shortly. It's great for their service department and new car sales but at the expense of their customers.

I did my trip, 850 miles total driving and it went great! Prior to doing the reset, we had the check engine light come on, throwing out codes like 'EGR', 'Intake bank * lean', etc.  After doing the reset and driving it for a week, my wife told me the check engine light went off.  So, I took off.  I topped off the tank at Costco, and as I pulled out, 10' feet from the pump, red triangle; 'stop safely now'.  So, stopped, restarted, drove away.  Then, drove down to Vegas, stopped at a Costco there, filled up, 10' out, red triangle... Again, turn off/back on again, drive out; no issues.  I got 33mpg for the trip down (I-15 is 80mph in Utah...) Spent 2 days, drove out, topped off in Mesquite (convenience store gas) and no red triangle.  I think I've established that the car doesn't like Costco gas...

 

At any rate, the vehicle is performing great! Mileage isn't quite what it was when I acquired it at 59k, it got between 38-41mpg then, but I'm much happier with low-30's mpg over the low-20's it has been over the past 18 months!  Thanks again Allen84!!

Sofiane- i did the reset and im in the albany ny area. Depends on how far in mass your at. 

 

Allen84 - I'm $ensing an opportunity here for you.  What if you had a kit consisting of an old cheapo laptop fully configured, and the OBD adapter. Customer pays shipping both ways for the kit.  Customer can either perform the reset themselves with the self enclosed instructions, or you remote login to the PC.   Return shipping label included, they drive to the local UPS store (in EV mode of course) and drop off.  All for a nominal fee (and deposit).  It seems Ford is avoiding the issue for the foreseeable future.

Thanks Allen

 

You da man!  I wanna send you some money. 

 

I just used this to restore hybrid function on my 2011 mkz hybrid with 248,000 miles, using a windows 7 laptop and elm327 cable off amazon. 

 

For my cable it only worked when I had the switch flipped away from the cable not towards the cable fyi.

 

I have a taxi fleet with toyota hybrids that have never failed a battery or lost battery performance. I have a hybrid highlander with 405k on the original battery and it still does nearly 30mpg with tons of battery power.

 

My toyota tech says the best thing you can do is drive these hybrids all the time. 

 

I have no fear of battery failure I just have fear of dealer service costs. 

 

I changed a hybrid battery pack out of a Prius that I bought with a failed battery and it's less complicated then this reset procedure.  I'm sure the ford hybrid batteries are just as durable.  

 

So reset your batteries fearlessly is how I feel.   You have nothing to lose.   

 

I don't know why ford would program these cars to stop using the batteries.   It seems silly to me.  These hybrids run forever with minimal maintenance.   

 

The change was immediate.   Before I couldn't accelerate without engine.  Now I can drive from a stoplight without any engine.  

 

I'm more excited about this then a grown man should be.

Just reset my wife's 2011 Fusion at 184,000 miles. Couldn't be easier. Waiting to see if there is any difference in the mileage. I'd be happy to help anyone in the Lancaster PA area. Thanks for the extremely helpful information (and for keeping me from needing to buy a new vehicle, cause my wife wasn't going to tolerate the lag for much longer)!

I already had thoughts on this, lol.  But it was only for the remote login support,  I did this with another member here, a couple of months ago. 

 

I will gladly help anyone out here. If they have a laptop.   If they don't have a laptop,  I'm sure they can borrow one from work, a friend, or family member, neighbor whatever, just for a day. Even for a couple of hours at most.  It is a 10  minute or less job.  

 

Then, the next thing is to buy the odb2 device from Amazon.  You can even return it for a full refund back to Amazon if you wanted it to, when you're done with it lol

 

The reason I wouldn't want to do the shipping the items route, is because I live in Canada (I'm guessing most FFH's are mostly in the US) .  Shipping these items would be subject it to customs duties, border fees and taxes.  Something that can't be avoided.

Allen,  I am interested in having you walk me through the reset process. I have ordered the odb2 device from amazon (delivery last week of January) and have a windows lap top, but being old and  dyslectic  I have a terrible time reading and following your excellent  procedure for resetting the clock.  I find the thought of messing with  my Hybrid terrifying  for fear that I might  do real damage with a slip up.  The Ford service department near me called yesterday and said they will fix my car as soon at the Ford Motor Co engineers tell them what to do.  This has been going on since my 2010 Hybrid stopped being a hybrid and I have little faith  that their fix will come any time soon.

Yes, shipping across the border is a show-stopper.   If the demand is there, I could facilitate assembling the kit & shipping.

I am lucky I have access to a number of mobile windows devices (a work laptop, a personal laptop, an old beat up 4 years of college laptop, a Surface Pro, etc), but if I didn't, and I still might do it, is an older Windows 8/10 Intel based tablet. $70 for the tablet, $10 for the OBDII adapter (USB or Bluetooth).

 

Using the Surface Pro for me is the best, as a tablet with a bluetooth keyboard seems the best with Forscan (or the shipped keyboard also).

 

I don't have an FFH but have driven a few as I would love to add one for a second car and possibly for a teen driver (if he ever felt like getting his license). But I use Torque on my phone and Forscan for Fords and other windows app for other makes, to help friends out (I usually end up giving them one of the really cheap $4-5 Bluetooth adapters).

I've had that same issue before. It was the electronic cooling system for the hybrid system. Yours could be something completely different though even need somebody with a Ford dealer level scan tool. Regular scan tools won't pick up the code

PRDobson, I had the same concerns. Allen kindly said you must have someone younger in your life to do it. Of course, my 24 year old grandson works for a software company. I bought the device, he brought the computer and had it fixed in 10 minutes. I drove him to lunch in my "like new" 2010 FFH.
