In the past, these issues were mostly caused by the 12 volt battery needing to be replaced. Your vehicle is around 5 yo so it sounds like it should be replaced. That's the easiest and most economical option.

In all the posts I've read on these forums, with the symptoms you are having, the recommendation is almost always to change the 12v battery. It's the easiest, cheapest and quickest option. It's old enough to be questionable and as you indicated, it's needs a charge, all indicators of a needed replacement. When my 2010 started to act weird I replaced mine. My 2019 is 4 years old but is not showing any issues, yet.

Is ECO on or off? (button on the console) On my 2019 when ECO is off my performance is excellent but mileage suffers a lot. With it on it's much slower off the line but if I drive more sedate I get very good mileage. My mpg for the 33k miles I've driven is currently at 46. Suffers a lot during the hot summer with A/C and winter with heater on. But 46 mpg for the 33k miles is more than acceptable for me.

I traded in my 2010 FFH for a new 2019 Titanium FFH on 12/28/18. At that time the battery reset was not known and circulated like it is today. Since I was dealing with a 9.5 year old vehicle I was looking at the usual set of long term issues too, i.e. tires, exhaust, etc. The 2010 was the most inexpensive vehicle I have ever owned. Other than the yearly oil & filter change and one set of tires I spent nothing else on any repairs. This is one of the main reasons I bought another hybrid. The 2019 Titanium FFH is a step up. It came loaded with I believe everything they offer and like the 2010 it continues to be a low maintenance vehicle. I do the Ford Works (oil change, filter and tire rotation) either every 10k miles or once a year as per the maintenance schedule. Other than that with 30k+ miles it's been great. Dan

Thanks for the clarification.

Just searched for the 2011 FFH online and it lists what I posted above. If you have the hybrid you have a eCVT and no change is recommend unless you have a problem. Link to the manual is (page 307): https://www.fordservicecontent.com/Ford_Content/catalog/owner_guides/11fhyog2e.pdf TRANSMISSION FLUID Checking electronically-controlled Continuously Variable Transmission (eCVT) The eCVT does not have an underhood transmission fluid dipstick. Your transmission does not consume fluid. It is designed to be filled for life. However, the fluid level should be checked if the transmission is not working properly, or if you notice some sign of fluid leakage. Transmission fluid should be checked and, if required, fluid should be added by an authorized dealer. Do not use supplemental transmission fluid additives, treatments or cleaning agents. The use of these materials may affect transmission operation and result in damage to internal transmission components. And the documentation is a bit unclear since it lists auto transmission and manual transmission. Neither are in the hybrid.

Here's what my owners manual says for my 2010: Checking electronically controlled Continuously Variable Transmission (eCVT) The eCVT does not have an underhood transmission fluid dipstick. Refer to your scheduled maintenance information for scheduled intervals for fluid checks and changes. Your transmission does not consume fluid. It is designed to be filled for life. However, the fluid level should be checked if the transmission is not working properly, or if you notice some sign of fluid leakage. Dan

Never experienced this on my 2010 or now on my 2019 FFH. Ford recommends 10k miles or once a year for oil changes. Had my 2010 almost 10 years and only did it once a year. Never any issues. While "The Works" package is reasonably priced, every 6 month may be a bit of an overkill. Any more frequent than that is just wasting money unless there is a good reason other than dealer profit. Dan

"Sealed" may be overkill. Sorry. My understanding it's not like the old transmissions with the fill and check capability from a tube in the engine compartment. You need to get under the vehicle and drain, fil and check from a small fill hole. It's also my understanding that CVTs don't have the frequency of fluid changing like auto trans. And CVT fluid is much more expensive. I usually follow the manufacturers recommendations unless there is a good reason to deviate. And while 150k may be a bit too long for some, 36k seems overkill unless there are some symptoms.

According to my owners manual the 2019 FFH transmission should be changed every 150k miles. Every 150,000 mi Change automatic transmission fluid. (240,000 km) The FFh uses a CVT. It's a sealed unit. Here's a link to get the manual: https://owner.ford.com/tools/account/how-tos/owner-manuals.html?year=2019&make=Ford&model=Fusion

If you follow this other thread you will see that looks like Ford released a TSB addressing the battery age problem: https://fordfusionhybridforum.com/topic/12638-wont-run-in-ev-mode-ice-kicks-in-immediately/page/10/#comments

Don't disagree with you but these are hybrids which Ford doesn't have decades of experience with. The 2005 Escape hybrid was their first foray into hybrid vehicles. Was thinking of getting one but price wise for us didn't pan out. And true that other Ford vehicles go 200k-300k miles, but Ford doesn't warranty them or do and TSBs other than safety recalls that I am aware of. So the expectation of Ford supporting a 10 year old vehicle hasn't been done before.

Instead of conspiracy theory how about planned obsolesce? No car manufacturer designs a vehicle to last forever. I remember many years ago (many) that 100k was the designed goal for a car. Nowadays cars can easily double or triple that with judicious maintenance. So, what is the planned obsolesce timeframe for a hybrid, where the engine may only run half as much as a non-hybrid vehicle? Just my thought. Dan

Should be in the first post on that thread from billford. I've copied the pdf below. Not sure if it will work 2010 to 2012 Fusion Hybrid.pdf

On another Ford Fusion Hybrid forum this was just posted. Could Ford now be addressing the battery age issue? https://fordfusionhybridforum.com/topic/13380-2010-2012-fusion-hybrid-high-voltage-battery-tsb-at-10-years-of-age/

I would start it every week or so and let it run for about 15 minutes. On my 2019 FFH Titanium, when we were on vacation last Oct, at the 2 week mark, I received a text from FordPass indicating it's been two weeks since the car was run, and it was going into sleep mode when I would not be able to remote start it. I would need to start it in the vehicle. So going forward if I plan on being away I can remote start it every week. Remote starts shuts off after 15 minutes.

Most who have read these forums, and this thread have applied the fix or had help. But how many don't read these forums and go to the dealer for help? So far perhaps one or two dealers have offered to do the fix. Most try and upsell a new battery. And of course, no one is going to put that amount of money into a 10 year old car. My own situation was, I experienced the lack of EV on my 2010 back in the fall of 2018. I actually looked into getting Greentech to replace the battery at the tune of about $4k. But they used reconditioned batteries and not OEM which they said would drive up the price over double. The fix by ALLEN84 advertised now wasn't even known at that time by the folks on these forums. So I traded it in on a 2019 FFH Titanium rather then pumping $4k+ into a 10 year old car with no guarantee it would solve the problem. I believe if Ford is pushed to recognize and offer a solution to this issue it will help a lot of folks who do not read these forums. Just my 2 cents.

HyperMiler19, Thanks for the links. I was not aware of these issues. My 2010 FFH was always serviced at the local dealer and I never noticed and swollen lug nuts. Perhaps it is more prevalent in states with harsher winter weather where more road salt is used. I will keep an eye on the 2019 FFH. But I do have the premium external warranty which covers me for 10 years or 80k miles. And given that there is no spare on this vehicle, I don't expect to be changing any tires. Dan

I've had mine since Dec 2018. Love it. Prior one was a 2010 FFH and loved it. These have been the least expensive vehicles I have ever owned. I haven't heard of any issues on them. What is this lug nut issue you're talking about? Dan

There is two temp dials on the dash. One for the driver and one for the passenger. Make sure the passenger temp setting isn't set to cold. If the small light on the passenger side is lit it's on and can be real easy to set it and not realize it. I believe you press the drivers temp setting to override the passenger side or just set it higher. If that does not work then it's something else.

My 2019 FFH Titanium doesn't make the noise.

Been thinking about adding a spare to the '19 Titanium I have. Looked through Ebay and found a bunch. Most list a 16" compact spare but a few have a "17 compact spare with tools for a few bucks more. My tires are 18" so would you think/recommend getting the "17 or it really doesn't matter since it's a compact spare meant to be driven short distances?

My understanding is EV means that portion of the drive you just took that the vehicle ran on electricity only (battery - EV = electric vehicle). Regen is that portion of the drive you just took that the vehicle was regeneration of electricity through the wheels to charge the battery. I'm sure others will have a more detailed or technically clearer explanation. Dan

Not much activity on this forum/thread about this issue. But as a followup to my prior post it seems there has been at least two successful alterations to the software that may help others.SOme concern as to why Ford isn't pushing this out and as always YMMV. On the following link page 9 are the procedure taken along with the concerns from a FFH owner: http://fordfusionhybridforum.com/topic/12638-wont-run-in-ev-mode-ice-kicks-in-immediately/page-9 Dan

Not sure if this is helpful to other with the battery issue in the older FFH. On another Fusion forum there is a poster who indicates he was able to get his issue fixed with a date change in the software. There is a bit of reading on the thread. I'm posting the last page of that thread. scroll to the bottom and you will see how that claim it was fixed. Not a lot of more current info but this dealer date resetting seems to be the least expensive and easiest option for those with the problem: http://fordfusionhybridforum.com/topic/12638-wont-run-in-ev-mode-ice-kicks-in-immediately/page-8
