📌 Ford Fusion FAQ – Common Questions & Answers Welcome to the unofficial FAQ for the Ford Fusion (2006–2020)! Whether you’re a new owner, potential buyer, or long-time driver, this post is here to answer the most common questions we see in the community.


🔧 General Questions

Q: What years was the Ford Fusion produced? A: The Ford Fusion was sold in North America from 2006 to 2020. It was discontinued after the 2020 model year.

Q: What engines are available in the Fusion? A: This depends on the model year:

2006–2009: 2.3L I4, 3.0L V6

2010–2012: Same as above, plus 2.5L I4 Hybrid option and 3.5L V6 (Sport)

2013–2020 (2nd Gen): 1.5L EcoBoost, 2.0L EcoBoost, 2.5L I4, 2.7L EcoBoost V6 (Sport model), and Hybrid/Plug-in Hybrid options.

Q: Is the Fusion reliable? A: Generally yes, especially the 2.5L naturally aspirated engine. However, EcoBoost engines (especially early 1.6L and some 2.0L) had issues with coolant intrusion and head gaskets in certain model years.


🛠️ Common Issues

Q: What are common problems with Ford Fusions? A: Depends on the year, but common issues include:

Transmission shudder (2010–2012)

Power steering failure (electric units on 2010–2014)

Coolant intrusion in EcoBoost engines (2014–2019, especially 1.5L and 2.0L)

APIM (infotainment) failures with Sync systems

Door latch recalls (2013–2016)

Q: What should I watch for when buying a used Fusion? A: Ask about:

Engine codes (especially misfires or coolant loss)

Transmission service history

Recalls completed (door latch, power steering, etc.)

Hybrid battery health if applicable


🧰 Maintenance

Q: When should I change the transmission fluid? A: Ford says 150k miles on sealed units, but many owners recommend every 60–80k miles to avoid issues.

Q: What type of oil does my Fusion use? A: Check your manual, but typically:

2.5L I4 – 5W-20

EcoBoost engines – 5W-30 or 5W-20 depending on year

Always use synthetic and a quality oil filter.

Q: Timing belt or chain? A: All Fusion engines use timing chains, which typically do not require regular replacement unless there's a failure.


🔌 Tech & Features

Q: Does my Fusion have Apple CarPlay/Android Auto? A: Available on 2017+ models with SYNC 3. Earlier SYNC versions do not support it, but some owners retrofit SYNC 3 modules.

Q: How do I update SYNC? A: Visit owner.ford.com and input your VIN. SYNC updates can be installed via USB drive.

Q: Can I remote start my Fusion? A: Many Fusion trims with key fobs or FordPass app (2018+) have remote start. It may be enabled via the dealer if not active.


⚙️ Performance & Mods

Q: Is the Fusion Sport worth it? A: If you're looking for power (325 hp, AWD, 2.7L V6), yes. It's the fastest Fusion ever made. Downsides: lower MPG, more complex engine, and discontinued after 2019.

Q: Can I tune my EcoBoost Fusion? A: Yes! Companies like Cobb, Livernois, and SCT offer tuners. Tuning can void warranty and increase wear—do your research.


💬 Final Tips

Always check for recalls (NHTSA or Ford site).

Keep up on coolant levels, especially with EcoBoosts.

If it starts overheating, stop driving immediately—coolant issues can wreck the engine fast.

Hybrids are solid but make sure the high-voltage battery is tested before buying.

New tire, alignment, shocks and struts, bushings and casings completely busted. Deemed a safety hazard until fixed. Hopefully it’s worth it to get it fixed and not spring for a new car.

Hello I have a 2014 fusion ecoboost car has been out of commission for a while with a misfire on cylinder one. Rings are shot and needs a new motor. Recently my friend has asked me what I would let it go for. Now I know I’m
Not sitting on a gold mine, but what’s a price for a fusion with a blown motor going for? Body is decent shape little corrosion on the hood interior is still nice no rips in the leather and it has options on it being a titanium.

Discussion For Fusion 2020 - had for about a month.... list of things we've had done to it so far

3 Upvotes

87,000 miles

Comes with a national powertrain warranty

Oil was changed shortly before we bought it. It had a 91% oil life left according to the computer.

Inspection to get a sticker for the state we live in. Brake fluid flush, engine air filter change and cabin air filter change

Had to replace the battery as it was low voltage. Had to have the alternator replaced.

Had some issues with the throttlebody. They took it out and cleaned it and it seems to be running fine now

Does all of this sound typical? We're really looking to get to a place where we don't have to constantly have it in the shop.

2018 Ford Fusion 2.0L EcoBoost — recurring P0303, low coolant, and gasoline smell in oil. Should I be worried about coolant intrusion

2 Upvotes

I recently bought a used 2018 Ford Fusion AWD with the 2.0L EcoBoost and am trying to figure out what’s going on before spending money on parts. I had a P0303 cylinder 3 misfire code that went away after clearing it, but it has since returned as a pending code even though the check-engine light is off and the car feels completely normal. I also noticed the coolant reservoir was below the MIN line, although the level seems relatively stable over the last day or so and I haven’t confirmed a consistent drop when the engine is completely cold. My oil is a little dark but not milky, the level seems normal and hasn’t noticeably risen, although it does smell somewhat like gasoline. I also noticed the long-term fuel trim was around +18% at idle but dropped to around +7–12% while driving, while short-term fuel trim stayed roughly between -2% and +3%. The engine maintains normal temperature, starts normally, and I haven’t noticed persistent white smoke or rough running. I’ve read about coolant intrusion issues on these engines, but I’m also wondering about an ignition coil, spark plug, injector, or PCV/intake leak. Has anyone experienced this combination of symptoms on their 2.0 EcoBoost? What would you test first, and what findings would distinguish a relatively inexpensive repair from internal coolant intrusion? I’d appreciate any advice, has anyone diagnosed this themselves.

2014 Ford Fusion Weird electrical issues

3 Upvotes

So this morning my buttons on my steering wheel, my turn signals, and my low, intermittent, and washer fluid functions stopped working on my 2014 SE. As well as all of my steering wheel buttons. I'm not sure what the issue was. But all of a sudden, they started working again.

It made me start wondering if my aftermarket android radio is the culprit. Occasionally I'll have to reboot it because I'll lose the steering wheel button functionality. I had noticed the wiper functions not working prior to the other things not working so I decided to reboot the radio and everything now works. So it made me think the issue the whole time was with the android radio. Is it possible that the steering wheel buttons not working also caused the wipers and turn signals to stop working?

I was originally thinking it could be a blown fuse or relay connected to the wipers but now I'm not so sure.

I paid $200 for the radio from China last year and I know you get what you pay for. For the most part, it's worked well for what I've expected from it. But if it's going to cause issues with my steering wheel buttons and signals and wipers, then I might just reinstall the factory 4" sync 1 radio and cd player and be done with the cheap Chinese radio. If that's even the culprit. I know the harness that plugs into the back of it has to have wires that go to the steering wheel and HVAC controls. But I just didn't think it would have wires for the wipers and turn signals in a harness. Like I said, the high speed wiper and the high beams worked on the steering wheel levers, but everything else didn't.

AWD system reliability?

2020 Ford Fusion 2.0 AWD, 80,000 miles.

I bought this as my first real car in July, and since then I have put ~5,000 miles on it. So far I have loved it, but recently I have heard a few sounds from the RDU area that concern me.

Beginning a couple of weeks ago, I have noticed a dull or hollow thump sound from the rear. It only occurred when turning at slow speeds, and occasionally over small bumps (while turning slowly) It was not exceptionally noticeable, but I did hear it a few times over the week. I had some baseball cleats in the back, so I removed them, and the noise disappeared for several days.

I thought the noise could just be my cleats rolling, but as it turns out it was not. As I turned onto the highway up a hill, I heard a sort of crunch or grind from the same area, but this time, much louder.

I was already planning to do a change of the fluid in the differential, and I’m wondering if it could help. I also am unfamiliar with what the issue could be, and if this AWD system is known to be reliable or not.

any insight into this issue or past experiences with similar cars would be extremely appreciated

additionally, what fluid for the differential housing, I am getting conflicting answers as to whether or not it is 80w-90 or 75 SAE

How common is HF35 Bearing/Transmission failure

3 Upvotes

Hi all!

I’m looking into purchasing a ford fusion and i had a chance to test drive a hybrid model from MY2013 with just over 100,000 miles. I’ve seen that the HF35 is known to have bad bearings and the cost to fix can be expensive because they either have to take out the transmission to fix it or outright replace it. For those who have seen this issue before was it at higher mileage and is it less of an if and more of a when for these transmissions?

Hi yall, im looking at getting a 2020 titanium. The only concern I have is the coolant intrusion problem. Ik the problem affects 2013 to 2019 2.0t engines but I would love to hear from other 2.0t engine owners to see if they still have problems or if the 2020 modle year is safe. Here is a link to the car if yall wanna check it out. https://www.luethjesales.com/inventory/details/used/Ford/Fusion/2020/Gladbrook/Iowa/6267540/F0825

I need to get my front number replaced and 1 mechanic gave me an estimate including active shutter, and 1 without active shutter. I don't know which one i had originally, but I want to keep it running smoothly.

Also, the bumper does have some hairline cracks in it so 1 said get a whole new bumper and the other will put the old bumper back on.

I'm just overall trying to decide what to do to extend the life of my car. any advice would be appreciated. thanks.

2020 Fusion Titanium energi wheel bearing issue

1 Upvotes

So my 2020 Fusion has 87k miles on it.
About 6 weeks ago I started hearing a grinding/clicking noise coming out of the front left wheel when I would turn the wheel and apply power to it.
3 weeks ago I took it to a mechanic, he looked at it and said the wheel bearing was damaged and falling apart.
He replaced it. I drove about 300 miles and then I started hearing the clicking again. I brought it back to him and he was shocked that the new wheel bearing was damaged and it was under warranty so he replaced it this past Saturday. I drove back home(180 miles) on Saturday in stop and go traffic through LA.
Sunday morning I went to go get coffee. Back out of the driveway, that damn clicking sound, again!
Drive 2 blocks, hit a dip then the front left wheel seizes up like I smashed the breaks and then keeps going.
At this point I know I can't drive this car much longer. Drove it down the street to a local mechanic and they looked at it and said I need a new wheel bearing/wheel hub (for the 3rd time) and a new axel on the front left.
They repair it and I go on my way. Today when driving I didn't hear any real noises, but over time am feeling the same delay in movement when I press on the gas from a stopped postion. And almost like a light clunking sound. I did hear a Couple clicks out of the front left wheel today, but nothing like before.
What the heck is going on?!

Also new mechanic said front motor mount is colapsedZ could this be the root of the issue? With the motor mount collapsed causing more pressure on the whole drive train?

2014 Fusion Hybrid transmission seal failure

Post image
6 Upvotes

My car is currently at 103k miles. I brought my car to a shop to replace a broken CV axle at 101k. At 102k I noticed the axle seal was leaking on the same side the CV was replaced(passenger). Now at 103k the seal is leaking again. The shop is replacing the CV again and the seal. I’m trying to figure out since they are using aftermarket CV axles if this could be causing the seal to go out. They just got a new seal in and it’s not lining up properly and they don’t know if it’s a seal issue or not. I know 100% it wasn’t leaking before the CV axle change because I just did a second drain and refill of the transmission and checked both seal prior to them doing any of the work.

Head Gasket Replacement

Post image
40 Upvotes

​

I just finished replacing the head gasket on my 2017 Platinum. It took me 9 days of working a few hours at a time. It felt really good to drive it for a half hour tonight to see if there were any gremlins.

It's not a small job but it is doable if you are very careful.

I used a Haynes manual and these videos for reference:

https://youtu.be/34municAvMQ?is=1KJ1judprZuqoaRD

https://youtu.be/sw16nUZV7JA?is=tCN7b1gS6C6g8fr8

I'm probably crazy for doing it but it seemed a shame to junk the car or do a full motor replacement. Neither of those options were in the budget and I couldn't afford to pay a shop to do the job.
