I have a 2017 1.5L SE with 144k miles on it. I bought it in 2018 with 79k miles already on it. Still going strong, no coolant problems, only had to replace an O2 sensor on it. Just take care of it, change your oil, don’t dog it when it’s cold. I would recommend getting a sport though down the road; these are super reliable as well and have so much power.

And synthetic oil!
I have this exact car. Got it with only 15k miles, now at 50k. No issues other than routine stuff so far.

I got it at 27k, 82k now on it. After 2 years. What’s your mpg that you average on it?
@Zyler
I’ve a 17 SE with the 1.5, got it at 62k, right at 130k now. No major issues for me, only regular oil changes and brakes. I got 26 mpg on average when I was doing mostly city driving. Mostly highway now, get 30+ consistently.
@Zyler
I will take a look when I drive to work on Monday… I’m curious about it now. I haven’t looked since I got it.
@Zyler
I’m getting 30-40 mpg. I have some photos if you want to compare yours.
Switch to a hybrid, imo.
I’ve a '13 with almost 177k. But mine is the 1.6 engine. I’m driving her until she tells me it is time… Good luck!
Save your money on something else.
The updated block didn’t get put into production cars until part way through the 2020 model year. Early 2019 was when they started replacing blown engines with the updated block. Ford knew of the problem and had the new engines, but why let thousands of premade engines go to waste so they continued to put them in until they were gone. They typically blow around 60k-ish miles. If your car has significantly more than that, it may have already been replaced. On top of the failing blocks, the transmissions aren’t great. While the 1.5L is technically a fuel-efficient engine, it’s quite underpowered for a car that heavy. There was a limited recall on some 17-18 1.5L cars. Drain and fill the transmission fluid immediately then every 30k miles in the future. Even with the new block, it’s just like any of these tiny turbo engines; it will require more maintenance than the 2.5L non-turbo available in these cars. At some point, the turbo will need to be replaced. There’s a lot of stuff that will eventually develop coolant leaks. I think these may have an internal belt that needs to be replaced; Ford has made a lot of bad engines to keep them straight.
It’s a 2017; they revised the block and coolant already by this time. The problem was the 1.5L and 1.6L from 2013-2015.
I have a 2019 with the 1.5L and I would honestly say to just take care of your 2017 and save for the repair. If your engine goes but everything else has been well maintained to have a new engine make sense then do it. Unless you plan on getting rid of it as a whole when the engine goes, then just make sure you stay on top of all of the maintenance. I don’t think it’s worth getting rid of it just to get another one a few years newer. I do agree with you about loving the car inside and out. Since they have discontinued the sedan that we all know and love, you might as well treat the one you got well. You never know how beat up a newer one could be if you swapped yours out now.
I had a 2014 SE with the 1.5L. Made it to around 189,000 miles without any engine-related problems. Two O2 sensor replacements was it. Maintain it with full synthetic motor oil. Flush the coolant at 100,000 miles. Change the engine air filter every 15k miles or so.
There’s a point of diminishing returns when cutting displacement. I believe the 1.5L actually will generally fare (worse) mileage than the 2.0 due to it needing to maintain higher revs to counteract its utter gutlessness. And this, combined with the weight of the car, = worst mileage. I just drove home from Taco Bell back home (about 7mi) in my 2.0 (Atkinson) and I got 46+ mpg. I’ve gotten up to 60 mpg avg on some drives… Oh… And mine’s a hybrid! 
RE: DON’T WASTE YOUR MONEY ON A “NEW” 1.5 FOR THAT CAR. Just buy a hybrid for $10k. They’re $10k with good miles.
From what I’ve read on this subreddit, the best Fusions to get are either the hybrid, 2.5L or the twin-turbo 2.7L sport. I have a 2020 Fusion Hybrid and I love it. Also, another thing to worry about besides the 1.5L EcoBoost is the 6F35 transmission. It’s recommended that you change the fluid every 30k miles.
I have the same question. I have a 2016 Fusion 1.5L. I do remember there was a problem with the motor at 50k miles: I was told the motor needs to be changed and they changed some parts. At that time, I didn’t care much about the problem since it was covered by the warranty. Do I still need to expect problems with the motor? Now I am at 120k.
We have a 2013 1.5 SE. 199,000 miles. We have a persistent coolant leak and no puddles on the floor. Apparently, the leak is getting into the combustion chamber but evaporating once we fire it up. So far it’s an irritant but it’s only a matter of time till something bad happens. It’s been a good car otherwise.

Consider using a head gasket sealant.
