Huge win for car owners! All TSBs to be made public. The Center for Auto Safety just made the NHTSA (US Government) make public the full text of all TSBs from now on. They are the same organization that has petitioned the NHTSA & filed lawsuits to protect car owners over exploding gas tanks & other major safety issues. Whenever you drive in your car, you are safer thanks in part to a lot of work over the years by this small but very effective consumer advocacy group.

2007 Kia Sorento Owner Comments

problem #6

Sorento 6-cyl

  • 47,760 miles


I own a 2007 Kia Sorento LX with 47,760 miles on it currently (today's date 09/10/2014). The first symptoms happened a few months ago where my car would hesitate upon acceleration and/or I would be traveling between 30-45 mph and the car would begin bucking/jerking for a few seconds. This was very intermittent and random. If I took my foot off the gas pedal, then reapplied the gas the car would be fine. Then that symptom went away and I gained a new symptom. I was driving approximately 30 mph, when all of the sudden my ecs off light and check engine light came on simultaneously, and I instantly lost power/acceleration. It appears that when this happens the car goes into "limp home" mode? it has happened twice to me in the past 3 days. This is very dangerous because the loss of power/acceleration is instant, it happens without warning, and it does not matter how fast you are going. This could cause loss of life if it happens on a highway at a high rate of speed. All of these symptoms began to appear right after I had the recalls done on my vehicle (I.e. brake switch and ECM upgrade). My car was fine before I had the recalls done.

  • 15,500 miles
At highway speeds, vehicle check engine light comes on and the power from accelerator greatly reduces. Appears to go into 1st gear, and vehicle only able to drive at 5mph. Stopped car on shoulder, turned engine off and parked. Restarted vehicle with no power or transmission problems; check engine light remained on. After 5 minutes of driving, repeat in activities. Occurred 5 times within 20 mile drive. Very unsafe to have occur on highway.

The vehicle was taken to the dealer who inspected the vehicle and informed her that the brake switch and throttle position sensor would need replacing. The manufacturer was notified who stated there were no recalls for the vehicle and offered no further assistance. The failure mileage was 70,436.

ESC and check engine light comes on my 07 Kia Sorento and loses power. This is a safety concern when driving on freeway speeds. I experienced this for the third time since owning the vehicle. Dealer repaired the throttle positioner two times and now for the third time, dealer will charge you if mileage is +60K. I believe this is a defect that Kia is trying to be mum about it. There are plenty of consumers on the Kia forum expressing disgust about the problem and the safety implications that can happen. I demand an investigation on this matter.

problem #1

  • 1,000 miles
When I press on the accelerator to increase my speed (like when merging, for instance), the car reacts as if I put it in neutral. It stops all forward motion for at least a second. Sometimes as long as five seconds. This has almost resulted in being hit from behind or the side several times. I have had it into the dealership several times, and have taken their mechanics for demonstration rides several times. I've even contacted their home office. Each time the answer is the same, "we can't find anything wrong. It must be you." I fully expect to be involved in a collision in the future caused by this dangerous defect. I can't afford to buy a new car, so I'm stuck with it. I hope you can help.
