The Sorento lurches at slower speeds and engine light comes on. It appears as if the transmission is slipping. At higher speeds it does not occur. The code from the engine light analysis is p0713 (transmission fluid temperature sensor). Kia forum shows a number of people have similar complaints.
Started vehicle and put into reverse, once in reverse I began to back up, the gear slips out of reverse into neutral. If placed back into gear park, reverse or drive it pauses for a few seconds then shifts hard with a clank sound. If you proceed to drive it shifts like it is going from first to third gear. It will not correct itself once driving. Sometimes when this happens I can turn the vehicle off and restart it and it works fine with no slipping or shifting problems, the check engine light does not come on. However today it will not correct itself and the check engine light has come on.
Automatic transmission slips on show upshifts, intermittently. Began @ 3500 miles. Check engine light came on. Code initially read as "transmission temp light fluid". Dealer reset code, could not duplicate problem. Check engine light recurred with same code for "transmission fluid temperature sensor". Continued intermittent problems with sluggish upstarts at low speeds and hard shifts into gear. Intermittent problems with check engine light displaying for 24 hours and then disappearing without storing code. Dealer replacing transmission @ 4800 miles.
