Question Common problems and annoyances

Hey everyone,

I'm a new owner of a 2016 base EcoBoost fastback with an automatic, and I was curious as to what commonly goes wrong with S550s in general, as well as the 2.3L specifically. Baseline things most owners find annoying about the factory cars, but aren't "problems" per say are welcome too.

So far this is what I've heard:

- Wheel hop and deflection is a killjoy
- Blow-by is a serious concern for the 2.3L
- Head gasket failure isn't common, but it isn't rare either
- A/C failure is pretty common (a problem with mine from the get-go)
- The automatic is good only for short intervals of spirited driving

Let me know what y'all think of these and what else is worth adding...

I have not experienced any of the issues you've listed, nor have I seen numerous posts complaining about any of those things. I too have a 2016 A/T Ecoboost.

As per Consumer Reports, there does seem to be an above normal rate of A/C failures on the 2015, 2016. But engine and transmission owner ratings are above average to excellent. Rear camera failure seems to occur often due to the wiring harness being too short between the trunk and trunk lid as described in Consumer Reports and my own experience detailed here:

But I have not encountered any major problems with my 2017 Ecoboost and love the car. The 2.3L Ecoboost is one of the most technologically advanced engines made today. Just compare it's HP and MPG ratings to any other 4 cylinder turbo made today from Chevy, Audi, Honda, Toyota, etc. The engine and trans seem quite reliable which in my opinion are the main things to be concerned about with any vehicle due to the potentially high repair costs. Most other repairs are relatively low cost in comparison.
