After 10 days and 500 miles of use this new vehicle was exhibiting signs of transmission problems. We noticed loss of power, shaking on takeoff and significant noise coming from the power train while driving; this affected the drivability and safety of the vehicle. We took it in to the dealership and they informed me of the fact they had to replace the transmission and transfer case because it was faulty. For some reason they did not put a new one in the car but rather a re-manufactured one. (a real mystery if you ask me) they said it was industry standard. But it sounds to me like they are hiding something.I hope someone looks into this because while we are glad nothing serious happened. It was scary for us since we have 4 children at all times in the car.

At an idle, this vehicle runs rough and shakes. It feels as though it will stall. I do not believe this should be happening with a new car. I told the mechanic at my first maintenance check, and he acted as if it would get better with an oil change. It seems to be getting worse. I commute 120 miles a day for work, and I have had the car for 5 months, it has 9000 miles now. Now the radio will not turn on? this concerns me that maybe something electrical is malfunctioning.

On 9-3-12 bought a new 2013 Kia Sorento with the base 4 engine. Next day noticed a vibration when idling in drive. The car shakes. Notified dealer immediately. Dealer noticed concern but could not address. No applicable service bulletin. In December dealer notified me of a possible solution. Dealer installed a new tensioner and alternator pulley. Changes did lesson the vibrations. But an unacceptable vibration still exists when idling in drive. The vibration disappears when the transmission is put in N when idling in drive.

2013 Kia Sorento 4 cylinder. While at stop light engine revved up and lunged forward. Applied harder brake until stop light turned green. Vehicle at dealership for two days so far waiting alternator replacement. Service department states never had to replace an alternator before and not in stock, waiting for overnight shipping for two days. Dealer states they have no control over defective parts, but will fix and service vehicle when parts arrive.

I purchased 2013 Kia Sorento 2.4 gdi last month. It vibrates and shakes at idle speed from day one. I was told by sales person that it will stop after driving for few miles. Now I have 1500 miles on it but it continues to vibrate at idle speed whether in gear or in park position. I called the dealership they say there was software upgrade for certain manufacture dates but it doesn't look like it applies to me based on my purchase date. But they say bring it in and we will check it. I am planning to go this week. Searching the web, it looks like lot of people have this issue. I hope it brings attention to Kia motors and they provide some fix.

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.

We leased a 2013 Kia sorrento on 8/11/2012. Vehicle had 4 miles when paperwork was done. On 8/25/2012 the check engine light came on. On 8/26/2012 the engine revved to 6,500 RPM when we were going 20 mph. There was a large bang. I took in to the dealer on 8/27/2012. I was told a new transmission needed to be installed after 2 days of "diagnostics". we now have been without the vehicle for almost as long as we have had the vehicle. I am told it will not be ready until at least this Wednesday. I frankly feel uncomfortable in taking the vehicle back in this condition. I have been told several times that I would be receiving a call from the national customer service desk at Kia. No call has ever come. We have received no calls from Kia's Consumer Affairs group though told repeatedly that such would occur.
