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.
