Does driving a 2019 Ford Expedition XLT in Eco mode reduce engine and transmission life?

Believe this might be the article @vintshave was talking about.

That article isn’t convincing at all. All fluff and no actual testing. Typical JD Power. Remember, JD Power also thinks Stellantis/Fiat products have the best initial quality year after year. And we all know that’s not true lol.

Eco mode on our particular vehicles does not change reliability. It only changes the pedal translation map. With a stock tune, anything hooked up to a 10r80 lugs the engine regardless of if your in normal or eco modes.

I have seen on Hondas in particular though that their Eco mode makes pretty dramatic differences in how their AC system and CVT transmissions react. Might be a more appropriate article for some of their stuff for sure.

I resemble that remark. My 2023 Dodge Durango R/T Premium TnG that I bought new has 13,000 miles and I've had no issues with it.

The 5.7 HEMI V8 has cylinder deactivation, aka multi displacement system (MDS). When you turn off ECO mode, it disables MDS. So, that's a clear case of ECO mode doing something.

But, this is a Ford forum and my point is that JD Power published an article that paints all cars sold in the U.S. with a broad brush. If you read all the way to the end of the article, you'll see: "Do not go to extremes and think that the Eco mode is definitely bad for the car."

But, I think that another statement from the article is the most important: "Also, note that there are many ways to achieve moderate fuel consumption without the activation of Eco mode." I'm an old fart and I still believe that the path to good fuel economy is fairly easy: Keep your tires properly inflated, keep your vehicle in a good state of tune, don't buy cheap gas, don't haul around a lot of unnecessary stuff, and drive like there's an egg between your foot and the throttle pedal.

Yep! Hard to do when you got two whistling snails under the hood though
