I purchased a 2019 Sorento EX V6/8 Spd Auto in November of 2018. This is my 6th Korean vehicle. ‘04 Santa Fe, ‘10 Sonata, ‘10 Santa Fe, ‘13 Sorento SX, ‘17 Forte, ‘19 Sorento EX. After a few months I began to notice a strange “chirping” noise at 1250 rpm in 8th gear only. The vehicle only had about 5,000 miles on the odo. I put up with it for a while unti it nearly drove me crazy. I took it to the dealer. The head service technician took it out and he noticed the noise also. He stated that he had never encountered this issue that he was going to put it on the Kia Service Web and to call back in a week. I called back and asked if he had any response from Kia. He said “Yes. Kia is going to replace your transmission. We have ordered one and I’d should be in by the end of the week.” I took it in and two days later I picked it up. The service manager stated that Kia was very anxious to get my old transmission. I do not think you could expect any better service from a dealer/manufacturer.

Great dealer service. In what city?

I doubt this is a kia/Hyundai transmission. There is one a lot of companies are using and all are having trouble with it. Ford Explorer has a 10 speed in their new 2020 which is suppose to be a good tranny. Between the 8 speed and rear coupler issue I would not be buying a new model. I don't want to undergo issues with these knowing there is a problem they need to resolve. Swapping out couplers under warranty is quick for them but they shouldn't be eating them up and no fix for older years yet.

I could be wrong, but I seem to remember reading that this eight speed auto was a Hyundai homegrown product. Not the Aisin eight speed that everyone else is using.

If its so then Kia needs to get one or more specialist the bring their own diagnostic computers and test drive these vehicles acting up once and for all. Resolve the problem(s). The 3.3L is not the issue nor should it be. I have it in Sante Fe 2008 I am selling, runs smooth as silk with frequent quality oil changes and Wix filters!!!

Knowone wants to spend two arms and a leg. Then have problems with the power train. Then let them fix the AWD coupler design issue which causes the early failure. Then they'd have something to be looked at seriously.
