Tl-the contact owns a2011 kia Sorento. The contact stated that while driving at 25 mph, making a left turned depressing the accelerated pedal a riddling noise occur, the vehicle failed to go forward. The vehicle was towed to a dealer where it was diagnosed that the transmission needed to be replaced. The vehicle was not repaired. The manufacturer was not made aware of the failure. The failure mileage was 32,700. Aw.

The vehicle abruptly jerks or changes gears when reducing speed. When taking the foot slowly off the gas pedal the vehicle jumps causing the vehicle to almost stop. The transmission also makes a very loud noise. Sometimes it just turns off by itself. Car is only 2 years and a half old and it's already having signs of breaking down and having problems that could cause accidents. Kia says they don't know what the problem is. I have taken the car to the dealer twice. The first time they cleaned the throttle body, but it didn't fix the problem. I have taken the car to the dealer again, still waiting for solution. Researching the internet, I found there are many similar complaints where kia just won't do anything. Actually I found this web page as a recommendation from one of the forums. Hope you can help.

Summary: update to below problem I bought my Sorento in 2004, new. I replaced the coolant reservoir at 61000 miles due to overheating, replaced the low beam headlight bulbs on 4 occasions, tail lights on 2 occasions. My vehicle, 5 speed manual transmission, started to have a roaring noise approx. 6 months ago and the u-joints were replaced. It still roars. It quit running on 2-16-12 while I was driving, but restarted. It finally quit again and would not restart on 2-17-12. Check engine light indicate a fuel pressure sensor problem, but mechanic says this should not cause the problem I presently have. It has been in the shop since 2-18-12. The mechanic said it started for him. I insisted he let it run for a while and see what happens. Sure enough, it quit. Kia mechanic told me it may be a crank or cam sensor issue. Other problems--front dome light off and on at will, rear one works, clock on and off at will, vehicle hums loudly when driving for a while. It has been a reliable vehicle for the most part, but when there is an issue, it is hard to detect. Above work was completed at a cost of 1126,00. But now crankshaft bolt broke while driving costing damage to engine heads. Vehicle went back into shop and is still waiting repairs. Kia owes it customers better service and must pay repair cost and take responsibility for the faulty crankshaft bolts they provide to the mechanics .

Placing the car in reverse resulted in a loud "clunk" felt in the transmission area. However, the vehicle drove normally for a short period of time (about 4 minutes). After entering a highway and beginning to accelerate to merge with traffic, there was a much larger "clunk" form the transmission area, followed by a metallic whining/whirring noise form the same area, and loss of speed. The engine remained running, but the vehicle would not accelerate. I pulled the car off the main road, and had a difficult time getting the car into the "park" gear so I could turn the vehicle off. Kia roadside assistance came and towed the vehicle to a kia dealership for replacement of the transmission.

After stopping to paying bridge toll, heard a loud grinding noise which sounded like something feel out from underneath the our 2011 kia Sorento. From that point on the vehicle would only coast. This could have caused a major accident as 3 lanes of traffic were merging and luckily there was a parking lot just before getting on the bridge. We called roadside assistance and vehicle was towed to kia dealership and transmission is being replaced. A rental car was provided, but is on a day-to-day basis. . . The repair is supposed to only take a week. . . Not sure how I feel about the vehicle now. . . . . There should be a recall. . .

1st problem: I bought the car, drove it off the lot, dealership did not get it inspected so I had to take it at 10 miles to get an inspection sticker on it! 2nd problem: immediately after buying the car, I noticed all the windows and doors rattled. Took it to kia in kingwood 5 times and they could never hear the sound and/or fixed other things on the car that did not need to be fixed. Problem still exists. 3rd problem: engine light kept coming on, 3 visits later, I needed a new transmission, at 13,000 miles. . Something wrong with sensor that measures fluids?? 4th problem: taking back at 14,500 miles on Monday(3/18/12) to get doors checked out now electronics are messed up and loud noise everytime I lock or roll down windows. Also, cant get key to turn in ignition alot!! what a piece of crap!!!!!!!!!!!!!!!!!!!!!!!!.
