I traded in my 2012 Hyundai Sonata because of the possible engine problems. I guess I should have walked away from Hyundai at that point but instead I took a bath on the Sonata and dropped 30 large on a Santa Fe. We took it to NC the first week we had it. I would set the cruise for 75 mph (so I would not get run over by Semi's) and the car on a slight hill would down shift from 6th to 5th gear for a split second and then drop another gear down to 4th and the rpm would jump to 5500 rpm. It did this every single incline. If the incline was big enough this stupid car would downshift going down the incline as well??
I told the dealer when I returned and got the deer in the headlight look. Well I have had this car for 9 months now and at 19,000 miles it is still doing it. I just got back from FLA (I live in Ohio) and this car must have shifted 200 times. It drove me so crazy that if they can not fix it I will have to unload it and this time I am done with Hyundai. I took the car to the dealer after FLA and of course they could not duplicate the problem on the test drive they did re-flash some firmware.
I will follow up with this complaint if this did fix the problem. As I told them I do not believe this is a transmission problem because when I take the car out of cruise it never downshifts 2 gears at one time. This has something to do with the cruise control logics and the fact that the car does not have enough horse power for such a big SUV.

Driving with cruise control set at 70 mph. When I approached a slight downgrade in the road the transmission violently downshifted and the engine revved up to 5500. Had to disengage the cruise control for the car to return to normal. Researched on internet and have found several same issues with no satisfaction from Hyundai,

The vehicle cannot properly shift automatically. When cruise control is activated, the vehicle will stumble and linger in an inappropriate gear, and will takes as long as 15 seconds to either up or downshift, and usually that's due to a complete stop. When cruise control is activated, the same issue occurs, but it has lingered as long as 20 seconds in that state. This happens on a daily basis. When I took it in to the dealership, the mechanic said that it's because the engineers designed the 2017 fleet to idle to "save gas mileage". I have it in a report and everything. So to all who are dealing with this issue, it appears that Hyundai did this intentionally and knowingly. And rather than admit this is a huge and dangerous flaw, they are ignoring it similarly to how they ignored the engine problems they had a couple of years back.
