2008 Santa Fe abrupt 2nd to 3rd cold shift?
It has done it since new (it only has about 8,000 miles on it now) and I do not like the behavior - it seems that something is wrong. I had it to the dealer a couple of weeks ago to check out the problem. They put a "flight recorder" on it and ran it cold and warm and said all parameters were in spec. It shifts fine once it warms up, but when the engine/trans is cold, the 2nd to 3rd shift is consistently abrupt. It even does it somewhat when the weather is warm (over 70 degrees F), but the problem gets worse the colder the weather (and therefore the longer the warm-up time for the engine/trans).
The dealer gave me some baloney about the adaptive transmission possibly causing the problem and they reset the computer for me so it would have to "relearn" the shift points. Did not make a bit of difference (and I drive very easy). One other owner on another board noted the same problem. I wonder if anyone else has noted the same thing?
There might be a problem with a limited number of them or they might all behave this way (although I think others would have posted before about it by now). Also, I used the "manual" shift a couple of times to verify if the abrupt shift is in the shift logic or in the actual shifting itself. The same abruptness was there whether I let the trans shift itself or if I shifted it - which makes me think it is a quirk of the transmission itself (or a trans problem). This is a worry to me because 1) I wonder if this is a sign of worse things to come from the trans and 2) even if it is normal behavior, if I ever sold it, anyone test driving it would immediately think something is wrong with the trans.
