Default 2021 F-150 V-6 engine issues?

My nephew tells me that the Ford F-150 pickups with a V-6 are notorious for having horrible problems with the turbo and blowing oil seals and gaskets on the engine itself.
Any truth to any of this?


Sure miss those days of being able to hunt a lease for a nominal cost that didnít create greed and a feeling of despair if you didnít kill something!

I run a 2012 F150, with the 3.5L Ecoboost. 186K miles in, and no trouble with seals or gaskets.

The only things I have had to fix are oxygen sensors, a water pump, and a starter.

Been a good engine for me, and I tow heavy trailers.

Don’t know about the 2021s, but my 2019 3.5 ecoboost only has had an issue with the cam phasers. Knock on wood. Ford replaced the cams under warranty. Have not heard of issues with the seals or turbos.

No problems with my 23 MPG, 2018 (non-ecoboost), V6.

I think that was more of the early Eco-boosts.

Not an issue. Long story short, a tiny percentage had an issue, and so it gets blown out of proportion. Just like the electrics on GM don't last because there are a lot of one headlight wonders out there. Or on like on my current car, the motor was "known" to start consuming oil, and need a full replacement. A new motor is currently $20k. Again, this issue happened on a tiny % of cars, but those owners made the most noise.

2013 f150 3.5 ecoboost here, going strong with just general maintenance. I'm guessing your nephew isn't a Ford guy?

The early 2.7's had an issue where you'd have a little blow by which would result in a puff of blue smoke on start up occasionally.

They also suffered early on from a leaking oil pan. Never a threat to the engine but a residual drip which would cause a mess over time.

Guy who calls on the company I work for had his phasers go out three or four times before the truck had 160,000 miles on it.

Nephew by marriage has one of the eco-boost v6's that overheats when you pull anything or have a load in the bed. Been that way since new.

No truth to that. I have two and driven three others with no problems. I abuse mine in rugged terrain that the average guy doesn't see.
Adios,

I don't remember the figures, but aren't the vast majority of 2011+ F150s on the road 3.5 ecoboosts? ie you hear about more problems with the ecoboost because there are way more on the road than 3.7s or 5.0s.

146,000 miles on a F-150 2014 EB engine. Not a single issue. Replaced fluids, filters, and 2 batteries. Pushed it harder than I did my previous 2 GMs w/5.3 which were also great.

In a 2019 F-150 with EB now. Needs the cam correction which Ford will handle.

What I hear on the turbos is that some lose the cooling line connection and that causes a quick failure. If you don't change your own fluids, better have trust in who you pay to do it.

yes the turbo lines that run from the back of the block to the turbo have crap orings and ford has done nothing to fix them...
they leak coolant but its a design flaw that they want so you have to bring it in for a new rubber oring on a fitting that gets glowing hot lol..

i personally have done this fix and it takes monkey hands and fingers to get the parts on and off

had ford used AN fittings there would be zero chance of leak, but then that would mean no service money

I looked under the hood of my dads new truck just now to confirm what engine it is and itís the same as yours, 3.5 eco boost. Hoping he has the same good luck you have had. There is a recall for aluminum driveshaft for some reason?


Sure miss those days of being able to hunt a lease for a nominal cost that didnít create greed and a feeling of despair if you didnít kill something!

Thanks very much for all the comments guys. Sounds like for the most part that these are not horribly prone to issues unless you get unlucky.
I do need to search to see if it has the extra towing package to help it run cooler when towing... wonít really tow a whole lot of weight with it and usually just a 20í big Tex trailer and side by side wheeler. Guessing 3500-4000#...

Could be said for just about any half ton, but mine (3.5) is a lot happier towing at 60-65 than 70+. Lower rpm, fewer downshifts (a lot fewer), and several mpg better. I would venture to guess most overheating issues stem from folks hauling too fast and allowing the trans to gear hunt.
