2017 Ford Fusion SE undrivable

Bought a used 2017 Ford Fusion in June 2023 from a Ford dealership. Literally as I drove off the lot, the wrench light turned on. I turned around and took it back, and they ended up having to replace the transmission. Car had 72,000 miles on it then. I’ve kept up on oil changes. A few weeks ago, I noticed the car would lag when accelerating. Check engine light came on. Took it to the shop, they replaced spark plugs, coils, and fuel injector. Got a call yesterday that the engine is compromised and pretty much not worth replacing the engine. Car only has 83,000 miles on it at this point. I’m pissed. Is this common? No car should have to have a transmission AND engine replaced this soon. Definitely given me a bad taste in my mouth on Fords.

I’m betting coolant intrusion. And the dealer should have known better than to think it was the ignition/fuel system when one of these starts misfiring; it’s almost always because there’s coolant in the cylinders. That was a dumb unnecessary repair they made you pay for.

Actually, because he didn’t fix the problem, he didn’t charge me.

Well that’s good at least.

Curious what fault they found to replace the plugs, coils, and injectors. Sounds like you were taken to the cleaners on that repair.

The diagnostics said it was misfiring.

So they replaced everything instead of actually figuring out what is faulty. That’s the shotgun method. Replace it all and hope you fixed it.

I have the 2017 SE 2.5 n/a 160,000 miles, ol reliable so far, no engine issues so far, oil change every 4,000. By far, most reliable Fusion after reading into every variant. It’s FWD, pretty basic trim. Bought it at 30,000 and have done every kind of driving with it; wheel bearings on all four corners and brakes are the only maintenance I’ve had to do.

I have a 2016 Ford Fusion Hybrid SE, and it’s running like a charm with 110,000 miles. I change the oil myself every 3-5 thousand miles, and I do all general maintenance myself (spark plugs, oil change, engine air filter, cabin air filter, throttle body, brake pads, rotors, and 12v battery).

When I first purchased the car, I remember bringing it to Ford for an oil change, and not only did they put the wrong amount of oil in my car, but they also added the wrong kind of oil. I highly suggest to anyone who doesn’t have some type of warranty on their car through Ford not to take their car there. Those people are crooks! I also suggest that you figure out how to do the general maintenance to your car yourself. A lot of mechanics are not trustworthy. They’re mostly out for your money, unfortunately. They’ll fix one thing and then mess up another so you would have to come back.

So, all in all, a car with only 83,000 miles with a nonfunctioning engine and transmission is definitely not common. These cars typically last about 200,000 miles, maybe more if you are someone who’s on top of everything in terms of maintenance and upkeep.

Good luck with your next car.

I have a 2017 1.5L SE and it has 144k miles on it. Runs great, shifts smooth, still gets upwards of 35mpg on the highway. Sorry for your luck man, what engine was in yours? You might be able to get a recall claim…

My car lags too when accelerating. It almost feels like it loses all power. Hmmm. What should I look out for? Coolant level? 50k miles.

What is Stern Law?

Check engine light came on my 2017 SE 2.0 ecoboost; somewhere I too feel the lag in acceleration, I’ll be taking it to the shop today. I hope it doesn’t end up with something major; I got the car just a week back.

Check your spark plugs for oil. Since they’re out, switch for brand new ones and switch coils too. Easy DIY and might save you a trip to the mechanic. Get Motorcraft brand only; they can be found on Amazon and AutoZone.

@Lian
Hopefully that’s their issue. I hoped these things would fix my car, because these two things are what a lot of people were assuming. As well as the diagnostics that showed it was misfiring.

@Dai
Please post what they find wrong with it. Hopefully you don’t have the same issue as me.
