I have a 2015 Sorento EX with a class three (3) hitch. I pull an 8' x 10' trailer five (5) days a week with my heavest load of 3,800 pounds. I use it for landscaping. I have had a entire pallet of bags of mulch and 40 bags of 80lbs of cement. Pulled with no problems and stopped without problems. Now the catch to all this is the mileage without problems. On the car I have 90,985 miles. Had a dodge truck before this SUV and I will stay with my Kia SUV.
I love the feel and comfort of driving this car. I wish it had better mileage in the city. The ECO boost is great on the open road. It's comfortable and the features are easy for the driver to manage. The cargo space is huge. It rides well too. You do feel some bumps in the road but not all of them. I love the car!
