After having my SFS for almost a month now, I'm noticing something strange with the gear shifting. Shifting through the first 2 or 3 gears tends to be a bit rough. Both when accelerating and decelerating. Does anyone else have this issue?

Nope...sounds like a dealer visit opportunity.

Nobody else experiences any weird transmission things? High, rough idle during a cold start? Hard shifts between 1st, 2nd and 3rd gears? Downshifting too early when descelerating, causing the vehicle to drag?

Sounds like a warranty issue for the dealer.

Let the dealer sort it out.

The downshifting on coast down is the one part that may be normal. It does get a bit better after you get about 12K and the transmission is broken in with learned shift points, but on coast down.......That feeling if engine braking was there on our 2007 Entourage with the 5 speed auto and is there on both my 2015 SFS and my wife's 2017 long. Not fond of it, but it is what it is.

If more folks were complaining on the 2018 model, I'd suspect a programming issue like on my 2017 with the "acceleration" issue. That was a TSB with I think a TCM reprogramming fix? Or maybe I'm getting it confused with my 2005 Equinox that *also* had a TCM reprogramming "Fix" for downshifting. As did my roomate's father's Toyota Avalon (forget which year).

I'd still take it to the dealer though. I'd think if it's a programming issue, any vehicle off the lot should "dupe" the issue, like some nice folks were able to do with the 2017 SFS and the acceleration issue.

Good luck!

I'm hoping it's a programming issue. I drove out to Cedar Point in Ohio yesterday with my kids for vacation. The Santa Fe did great on the 468 mile trip! Only 26 MPG though But, this morning, after a cold start, the harsh shifting occurred, especially from 2nd to 3rd. It made a clicking, almost grinding, type of sound. It seems to get better as the engine warms up.

Definitely sounds like something needs "looking at".

On our most recent 210 mile jaunt...we averaged 28.8 MPG with our 2.0T Ultimate.

AWD?

Nope...but "hauling" pretty fast most of the way...which isn't the ideal for MPG results as we all know...was actually quite pleased with that number.

Is it in normal or sport mode? Big difference in shift points. If you're driving normal in sport mode it might feel like there is a problem...ie taking a long time to shift etc

Normal mode.

I have a 2018 SFS and in my opinion at times the shifts are a bit harsh or "confused" might be a better description, especially when cold. I find this under very light throttle the trans wants to upshift too early and then it starts gear hunting and can lead to a harsh shift or two. I often put the car in Sport mode when driving slow or when its cold and starting off slow to avoid this and it helps hold gear longer and avoid confused early upshifts. I don't think this is a mechanical issue but rather more of an annoying characteristic of this car, but I could be wrong. Overall I'm happy with it.
