I've had a bang & slight rocking motion at low speed seemingly while shifting 1st to 2nd or vice versa. It's been quite noticeable. This has happened 4 times now since February. The first time the vehicle was about 3 weeks old. I took it to the dealer and of course this event did not happen for them. I picked it up today at 2PM and it repeated the bang within 20 minutes, so I took it back again.
Interesting. Sounds similar to my experiences. At least I know I'm not alone now. Keep us updated.

Take it to the dealer and have them check the automatic transmission fluid level. This is a more involved process than just pulling a dipstick on this transmission. They have to go through an involved process to check it, but there have been issues with the fluid level being below normal causing this exact shifting problem.

It's been in the shop since Saturday April 11, so 5 days now. The dealer has driven it several times and of course the problem does not re-occur. Just my luck. But, the last two times I picked it up from them, the bang occurred on the way home from the shop.

I'll quiz them today on the fluid level as [b]GenCoupe10 has suggested. (Thanks for the suggestion)

That is no good to say the least. Our 2010 seems to jump forward a bit every once and while when starting up the engine which I thought I saw a post about somewhere but can not find it. No clunks as you mention so far though with ours.

Good suggestion on the transmission fluid level. I'll ask about that when we take it in.

So we've been recording all the characteristics of when the problem occurs... Up until recently the problem had only seemed to occur when the car was cold. That is, in the first 5 minutes of driving from a cold start. But on the weekend I had the issue where it revs up high and seems to be in neutral mid-shift occur after a good 20 minutes of highway driving followed by some stop-and-go. So to me, this sounds like a new piece of data.

Hi rpm123,
I found your problem very interesting. Although I do not have a Santa Fe yet (still waiting for one) I had a very similar situation with my Toyota Camry. I know they are 2 differant cars but my transmission issue was exactly the same as yours. Would only happen when it was cold, and of course the dealer could not duplicate the issue. I left the car at the dealers many times and still no luck. Like you I documented every time it happened and every time I was at the dealer. Believe it or not this went on for over a year. One issue was that once the car warmed up (about 10 minutes) the problem was gone. Then I read in a forum like this one (for Toyota's) about many other owners having the same issue and that a TSB was issued. I then went back to the dealer again with the information in my hand and finally got the service manager to make the repairs. Guess what, the whole problem all along was with the computer. They had to "reflash" the Transmission Control Module. The car now shifts perfectly. It was like installing an update for your computer at home. Can't say that this is your problem, but you never know, since the computer these days pretty much runs the whole car.
Good Luck,
Bob

It has done it 3 times now since I picked up my Sante Fe from the dealer, while my wife was driving it. 2 times were at 30 km/hr, 1500 rpm, while easing off the accelerator in traffic, then thud! The last time was at 40 km/hr, 1000 rpm, while easing off the accelerator in traffic, then thud! Scared my wife because she felt it was coming from right under her seat. All 3 times the temperature was between 6 and 10 degrees Celsius, so on cool days.

There is a TSB on this, the TSB number is 10-AT-006 dated March 2010 for MY2010 Santa fe, Sonata, and Tucson, I found it on hmaservice.com. It is for harsh or delayed shift problems on the 6-speed auto. Like I mentioned mine was doing this, since they reset the adaptive learning values it has not done it again. Hope this helps.

Thanks, jb10!!! This is great!

However... I called my dealer and they basically don't care. They said this is an american TSB, and there isn't one for Canada. They said they can't even see it - which I find hard to believe. This is the same problem I had with my Honda a few years back where they kept saying there was no TSB in Canada for the issue I had and they couldn't do anything about the problem. They refused to try to apply the same fix. About 6 months later the exact same TSB came out in Canada and then they just applied the fix and the problem went away. So frustrating...

They went through the whole speech about how they need to reproduce the problem before they'll do anything... I asked them multiple times to try just flashing the TCM since that would cost both me and them less time and money and is a zero-risk fix with no parts to change, etc. They kept saying that without reproducing they won't do anything. Which I do understand... but the problem is so intermittent. In the end, I got them to agree to take the car for a day and they'll have someone drive it once an hour for the day to try to reproduce. And if by the end of the day, they haven't been able to repro, that they will just flash it. I'm not sure if I believe whether they'll actually do this or not, but I'll keep you all updated.

I have a dealer login, and your 10-AT-006 is not on my AT menu...
