A day after I purchased a new Kia Sorento ex gdi 2013 (9/25/2012), I noticed that it had rough idle at stop. I took my car to dealership to fix the rough idle issue next day, however after 4 days of troubleshooting by mechanic with Kia support engineer, they were not able to resolve it. Tsb#122 (ECM software upgrade) was alreay applied prior to my purchase. Even today, I still have the same issue. My current mileage is 2800 miles.

The vehicle shakes whenever it's idling in drive and while your braked.. I took to my Kia dealership who said they are aware of the problem to bring it in. I brought it in they had it for 20 minutes and said its all set. Well let me tell you it's not fixed! I called and old he dealership and now I have to bring it in again. The vibration only goes away if when you come to a stop and put the shifter in neutral.

4 cyl rough idle at stop light and excessive vibration. Notice when drove new car off lot. Assumed it was normal. Had to make a long trip. After returning from trip had car service. I was told upon it was a computer problem and would be fixed --no definite time. Service rep was cornered and said could be 30-60 days. After many attempts to call dealer and write an extensive note--seemed to get stonewalled byg being told--working on it and will let you know. Finally on Aug 16 took car in and had a "computer adjustment for rough idle". much better, but only a few miles since recall notice and fix. I have not yet received an official recall notice-- I feel that Kia corporate intentionally did not divulge this problem to automobile safety officials for the purpose of continuing to sell the 4 cylinder Sorentos-poor decision.

While on vacation (June 15) we were to stop by the dealer and get our new tags. On I77 at mileage marker 33 in very heavy traffic, the engine quit running. I immediately turned on the emergency flashers. We were in the middle lane and wasn't able to get over to the right (nobody would let us get out of the lane we were in) to get to a safe place.we almost caused multiple accidents. My wife was screaming. I thought that we were going to create a major accident. No matter what I did I was not able to get the car started and it came to a complete stop. People were going around us on both sides beeping their horns and other gestures. After fooling with the gear shifter, I put the vehicle in park it started but when I put it in drive it started to miss and was in the process of stalling when I put it in neutral the engine started to run fine. I then put it in low gear and it started to move forward, once I got some speed (did not look at the speedometer to see how fast I was going) I put it in drive and everything was fine after that. Also, the vehicle runs rough when in neutral and while idling when in gear (varies with no rhyme or reason). The service advisor informed me that Kia knew of the problem and were working on it. They should have an answer within two weeks. It is August 13 and that was June 15. On August 7 it happened again...having other problems at times, vehicle missing, starting to stall....I have called the dealership each time a problem happened...so far all I got is lip service. Called several hours ago (talked to the salesman) said he was with a customer and will get back to me. No response from him so far. I am at a lost as to what to do my wife is scared and will not drive the vehicle. I am worried that I may cause an accident. Please help me get this problem solved before someone gets hurt or even worst.

Driving on the freeway in slow traffic. Suddenly the engine died with no warning. I had to stop in the middle of the freeway to attempt to restart the car. It did not immediately start, but after a few moments the engine kicked over. I drove it off the freeway and had it towed the next day to the dealer. After having the car for a week the dealer says that they "can't duplicate the problem" so they won't fix it. They say there is no "code" for the problem. This is not a safe car to drive if the engine dies on the freeway. If Kia can't determine the problem they need to recall this car.

I test drove the vehicle which had only 5 miles on it and had not been test driven prior to me. I noticed a very slight vibration from 0mpg to 10mpg, and asked the sales associate if that was normal. He said it was fine and was nothing to be concerned about. I did not notice any further issues while idling at stop lights and did not notice the vibration again during the test drive. After I signed the financial papers at 11pm after the dealership had officially closed for the day and got into the car to drive home, I was sitting in the car while it idled and I was speaking to the sales associate when the car began to shake and the vibration was very noticeable. I immediately told the associate and he said to bring the car in to the service department the following day to have it inspected and said it was nothing to worry about. He said it's under warranty so it would be taken care of one way or another. We brought the car in the next day and the service man told my husband it was likely just that it needed to break-in since it only had a few miles on it. They ran tests on the car and everything checked out fine. The man suggested we take it for a long drive and put a couple hundred miles on it and see how it was running afterward. We did so and the problem did not get better. We brought it in the next day to be inspected again and the service men took it for a short drive to see if they could replicate the problem and they noted they did. Our sales associate told us he looked into this vibration problem and found that Kia was aware of the problem and were working on a fix for a computer chip that was affecting the 4 cylinder 2013 Sorentos. He told us Kia did not have a timeframe for fixing the problem but it should be soon, but this was a problem with all 4 cylinders that they are making.
