Driving on highway and heard a loud knocking noise like something was loose in engine. No acceleration and luckily had an exit close to pull off side of the road. Car would turn on, but would not drive at all. Car was towed to nearby dealership. We were 8 hours away from home when this happened. Kia was not helpful at all with dealing with this. Customer service was terrible. We had all paperwork for oil changes in car and they made the dealership fax them over before starting any work - which happened to be 4 days later because they still didn't want to authorize Kia to work on the car. Kia made it seem like we had done something wrong even though the car only had 19,000 miles on it. We finally got the car authorized to work on and were authorized to get a rental car (on day 5). We went back home, the car was stuck in town 8 hours away getting worked on. When car was done, Kia wanted my husband to drive 8 hours to pick up the car! they argued and argued with us until they finally agreed to put it on a truck and have it transported. Service paperwork showed that there was a lot of metal debris in bottom of oil pan. They replaced the long block assembly. When they replaced that, they found the oil filter to be damaged and replaced that as well.

I am beyond disappointed in my 2012 Kia Sorento. It all started when my Sorento began to vibrate when traveling at interstate speed, then it just led to more complex problems. I can be driving down the interstate at normal interstate speed of 70 or going 50 and it will go crazy making unusual sounds and all the lights start going crazy. Then the whole vehicle shuts off. This is very concerning since I have a 2 year old and 1 year old in my back seat and it always seems to happen when I am in a high traffic area. I purchased the Sorento because it is suppose to be considered a family vehicle. That's isn't it. I can be traveling in town or where ever and when at a yield entrance way I can pull into the main road and what do you know. The Sorento stalls out. It doesn't want to increase speed. This same thing also happens while I am speeding up as well. It gets up to 5rpm before changing gears. I can't let off or I will get rear ended. My Sorento also has a horrible pull to the right. I have put new tires, had numerous alignments and all. Nothing helps it. It has never been in any accident whatsoever, but if these problems keep up there seems to be one in the near future. I have also took it to several dealerships to get the other issues checked out but I get the same response. "they never can figure anything out" I have got several other people to drive it as well just to be sure it wasn't the way I drove. I am to the point where I am terrified to drive it and especially allow my children to ride in it. I'm sure all of us with the similar issues are not imaging things. I am so frustrated and to the point I want to consider a lawsuit because I really don't want a fatal wreck resulted from these malfunctions to finally make someone do something about these issues. Not my family, your family, or anyone else's. please help us! our lives and our children's lives are at risk!

I leased my Kia Sorento 2012 LX V6 AWD new, after about 5 or 6 months I noticed when breaking to slow down the car the engine sometimes stalls completely, once I shift back in N I can restart the engine. This happens completely randomly, there is no rhyme or reason, there is absolutely nothing preceding this incident, it happens on its own, once actually it happened while the car was completely stopped at red light. I have been to the dealership many many times, they even went so far as to calling a Kia field tech to come inspect the car, lastly they installed an electronic device which was apparently recording anything happening to your engine, and sure enough about a week after installation I had the same issue, I pressed the button but upon returning to Kia dealership I was told the device had not recorded anything, apparently no codes are generated when the engine stalls this way. I have no idea how this can be resolved since no one knows how exactly this occurs and the issue cannot even be replicated.

When I am slowing down to around 20 mph, the car completely shuts down. No power, at all.

While driving at freeway speeds (55-65 mph) our vehicle spontaneously shut down; all electrical powered off, engine shut down, loss of ABS, loss of power steering. The vehicle would not restart until shifting into 'park' position. This was the third time this has happened, all under the same circumstances.

My family and I (wife, 4 year old daughter and 9 month old daughter) had just exited the freeway and entered our housing complex. While driving through the neighborhood our vehicle's engine as well as all electrical components turned off. We were in motion at the time it turned off. We had another vehicle behind us, but luckily they saw our vehicle slowing down and drove around us. My wife was driving and stated everything locked up and, as expected, she had to muscle the steering to pull to the side and out of the way of traffic. The brake pedal was also depressed all the way to the floor, and had no ABS. We had to wait for the vehicle to come to a complete stop then put the vehicle in park and start the engine back up. I initially told my wife to put it in neutral but after trying that, it did not work. After we got the vehicle back on we drove straight home. I contacted citrus Kia that day and told them what had happened. I was told that they have not heard of that issue and would have no way confirming what happened unless it did it while they were inspecting it. My vehicle was being serviced from 4/10/13- 4/13/13. The end result is that they could not locate the problem but did do a number of inspections to "hopefully" prevent the problem from re-occurring. They told me there is nothing more they could do as they have no way of actually verifying why the vehicle shut off while in motion. As of this writing I was advised I could come down and pick up my vehicle, but will refuse until the problem is found and resolved, as this is my wife's vehicle and I do not want this same problem happening and it resulting in a injury or fatal collision. I have read edmunds.com (townhall-talk.edmunds.com/direct/view/.F13B7ca/40) and see similar complaints with no resolution. Please please help.

I was stopped at red light when all warning lights came on. Started through intersection when car died in middle of busy intersection. Had to have car towed. Was told they found code P2110 limp home mode. This could be potentially very dangerous if it occured on interstate.

On 08/12/12 while driving in cruise control at approximately 72-74 mph, I eased out into the passing lane to put myself behind someone going faster. The car suddenly downshifted and accelerated with maximum throttle. I touched the brake pedal moderately to disconnect the cruise control. The car continued at maximum acceleration and in the passing gear. I then applied the brakes with great vigor and the cruise control disconnected and the vehicle slowed down. After a short while I reactivated the cruise control and drove about 60 miles without any further malfunction. I presented the car to the Kia dealer service advisor. The car was checked and I was told they could find nothing wrong with the cruise control. I asked them if they reported these very dangerous observations to Kia or NHTSA. They said no they never do. Incidental to this event, I had an engine malfunction light on 7/25/12. I took it in for service the next day and told it was a transmission heat sensor. A part was ordered and I was told to drive the car normally. Within several days, I became aware the cruise control was not activating when driving the first time in a day. But if the engine was stopped and restarted, the cruise control worked normally. I duplicated this 3 distinct times exactly as written. The service department was not able to link the difficulty to anything they had seen or read, they summerized it may have been a brake light sensor that failed but the computer dispelled that notion.
