We have owned 2 Sorento's for a total of 14 years. The first, an 03, I traded in when it was a little over 3 years old. It was getting about 9 miles to the gallon and was a big disappointment. I traded it in for an 07 which was trouble from the beginning. It was delivered with a broken sunroof, slit in the leather seat and the passenger seat didn't acknowledge there was a passenger in it. We brought it back to the dealer(s) (Boch, Norwood MA) at least 5 or 6 times in the first couple of months. The dealer we bought it from dropped Kia within a couple of months after buying the car. We then switched to (another dealer, they dropped Kia a few months later. Next there was a problem with clutch slip in the rear end. This took Kia almost a year to come up with a fix. We had to drive 40 miles to a third and only dealership as the others dropped the line. In 2015 it developed a problem with a bearing in the engine (30K) and was repaired under warranty. In 2016 oil was pouring out from the area the dealership (Quirk) had done the bearing repair. They cleaned it and told me there was nothing wrong. I picked it up and brought it to a local repair shop and they told me it was still spewing oil and it appeared they (Quirk Kia, Braintree MA) stuffed gasket cement where the leak was coming from. Brought it back and they worked on it for several days. My daughter took it up to U Maine Orono last month and the car died a couple weeks later. Drove it to the Bangor Dealer who said the car was not worth fixing (42K miles). The electronic throttle control had gone, which I get the car is 10 years old. While on the lift he informed us that the engine is pouring oil out (same fix from Quirk) and the rear end mounts were completely rotted through. Looking on line this has been a huge issue for Kia worldwide and has been recalled in Europe. Not here yet. This car was a third car for us from day one and my wife used it to travel to work in the next time. It was rarely driven on the highway and as you can see only had 42 K on it which about 12k of was put on by my daughter in the last year. I've been waiting for 11 days from Kia. Never contacted any of the dealerships involved. Looks like were going to court.
Bought new at year end 2007. Still going strong in 2015 at 215,000 miles. I have hit 2 dear and ridden the poorly maintained roads in the Southeast. I've put two sets of tires and 1 set of brakes. 0 dealer maintenance. (maybe that's the secret).
