Its hard to quantify based on quantities. 50x more ecoboosts sold would be 50x more issues and still be equal between the 2 engines on reliability. Not saying you're not right, but the logic is not.

Lo

Lol you think a 4 cylinder pushing 18-20 pounds of boost is more reliable than the most bullet proof v8 on the market?. You do realize ford tested the coyote at 800 hp and certified that it met its 100k miles tests. You can literally rag on the coyote every day and it will be fine as long as you check the oil every 1-2k miles and top it off.

Not what I think. What that video stated. I'm just sharing info, not trolling.

Actually, the Ecoboost is more reliable than the Coyote according to this source (skip to 5:28):

And they don't even say how they determine that.

Service appointment numbers?

Replaced engines?

Repairs made?

Useless.

Reliable engines don't get nicknamed 'EcoBoom'

So I was happily driving along in my 2024 Ecoboost Premium with just under 5K. All of sudden it started misfiring and got engine light. Bummer!
Turns out, I am told, a part of the #4 spark plug broke off and trashed the cylinder and turbo.
Got it back with new (“single use”) long block and turbo.
I’ve put about 100 miles on it, and noticed hood flutter and on a close look the hood is a bit out of alignment. I was so focused on looking for dents and paint chips that I missed it. Called service and they said they will send a tech to my house to fix it and also do the BCM recall. So that’s cool.
Anyway it took 30 days to get the car back, but seat of pants says it’s running just like it did before. Of course for 30 daze I had to answer everybody the question “where is your Mustang?” - very embarrassing. I’m 72 never had a motor let loose on me - I guess my luck ran out - hope I have better luck with this motor.
My question to you all - what does “single use” long block and turbo mean?
Thanks!

The ecoboost in the mustang is a modernized open deck version of the 2.3 engine ford and mazda developed that they put in the mazda speed 3. Back then it what gave mazda the zoom zoom boom stereo type.

I don't know what Ford did to it, but the Mazda 2.3 was the go to for high power MX5 turbo set ups. No one seemed to have reliability problems

Would that be the Youtube font of all truth?
I don't believe a fraction of what's said unless they prove their credibility in some way.

Great info - thanx!!

Thanks for all the feedback. I can say that the dealer rep told me that they never saw a failure specifically like I had, and that since ‘24s came out they have had two other 2.3 Ecoboost 24/25 motors let go. Out of how many I have no idea. But he also told me that all day everyday they are doing blown motors and transmissions on F series. Ecoboost and 5.0 he said. How much truth lies here who knows, but when I went to the lot to empty out my car after the diagnosis, it was full of late model F series I would assume still under warranty.

Related my GF’s VW Taos just had a head gasket repair at 30K miles, thankfully under warranty, and a friend just did a GMC tranny out of warranty- cost big $. All in all very disappointing.

I remember in the 60’s a lot of times engines were burning oil by 50k miles but I can’t remember anybody I knew having one just blow unless it was gross beating on it. I knew guys who purposely ran without air cleaners even. Where I lived cars rusted out before engines quit.

What’s sad is i love driving this Mustang, the power, handling, steering, etc., it’s just a blast. So I guess I’ll just try to treat it right, enjoy, and hope for the best.

I’ve put 250 miles on my new motor now, runs fine, keeping eye on fluids, fingers crossed!

I think the reason is that the old time engines were low stressed; low revs, low power, low compression etc.
I remember my Dads Holden running it's conrod bearings. The fix was simple, crank grind, new shells, new rings for luck, and off it went.
These days of high specific outputs and revs, it's a matter of seconds before bearing knock turns into a spun bearing and a rod going walkabout.
I'm still taken back at the number of catastrophic blow ups of stock modern engines.

The boosted 2.3 in the mazda speed gen 1 and gen2 was known to have reliability issues with the timing chain and vvt actuator as well as premature turbo failures and leaks. They also had trash fuel pumps stock to where owner had to change the fuel pump internals just to be able to run an intake or downpipe without running it lean. It has definitely gotten alot more reliable since ford tinkered with it over the years.

 

[robvas]

They sell what, 600,000 F150's a year compared to 20,000 EcoBoost mustangs?

hopefully the new block design of the 2020 or whatever year it was holds up better than the old ones

I bet half or more of the f150's are ecoboost. I buy 1 to 2 coyote f150's a year. Very few on the lots. Bronco, ranger, escape (and more) are all ecoboost also.

OK, we may be talking about different engines. The one's I was referring to were late 80's, early 90's
