Owner reports
Selected complaints filed with NHTSA by 2007 Kia Sedona owners, lightly cleaned up (personal details are redacted by NHTSA).
While driving the vehicle, you suddenly loose power. The ESC off light and engine light come on. You are not able to accelerate. It's like the pedal is not there. You could be going 50 MPH and then suddenly drop down to 20 to 30 MPH without warning. There is a few codes that come up: p2106 throttle actuator control system-forced limited power p2138. Throttle/pedal position sensor/switch "d"/"e" voltage correlation. There are other codes that came up before and it also caused these issues. This happens while you are driving. Sometimes you can tell its going to turn on the ESC light and engine light and going to loose power and sometimes it happens all of a sudden. When researching online about this problem, its a common problem with Kia especially the sedonas.
Tl contact owns a 2007 Kia Sedona. The contact noticed that the computer in the vehicle would sometimes accelerate on its own. The first instance occurred while test driving the vehicle. The vehicle accelerated when he removed his foot from the brake pedal. The dealer stated that the failure was caused by the vehicle being parked on the sales lot for months. Two weeks after purchasing the vehicle, the failure recurred. While driving in reverse at 20 MPH, the contact crashed into a fencepost due to the failure. He took the vehicle to the dealer nine times for a diagnostic, but no error codes could be found. The manufacturer did not assist. The current mileage was 42,833 and failure mileage was 30,193.
City driving down a busy road at 45 miles an hour and the car speed began dropping, check engine light came on, and gas pedal would go all the way to the floor but not give gas to the engine. Pulled car into a nearby parking lot. After sitting for about 15 minutes, my mechanic showed up. He started the car and the gas pedal worked. We drove it to my home. Now I am afraid to drive it, it could happen again, and cost for fuel system repair is huge for me!
Tl* the contact owns a 2007 Kia Sedona. While driving at approximately 25 MPH, the vehicle accelerated independently. The brake pedal was depressed, but the vehicle continued to accelerate. In order to stop the vehicle, it had to be restarted. The vehicle was not diagnosed or repaired. The manufacturer was not notified of the failure. The approximate failure mileage was 61,000.
While driving my husbands Kia it picks up speed if going over 40 MPH it will shut off and we get no power to the gas peddle it holds alot of heat from the motor the side doors open and close when they want ..but my biggest issue is the gas peddle and the shutting off while driving.
This is a brand new 2007 Kia Sedona. I was merging on a highway and pressed the acceleration pedal as usual when I noticed immediately that the car was stuck on the acceleration mode despite the fact my foot was no longer on the gas pedal. The car would not slow down or stop despite my foot pressing firming them slamming the brakes. In fact the engine/motor kept racing even though now I was slamming on the emergency brakes. Although I could not look down at the dashboard, my minivan must have been going over 100mph in moderate traffic. This continued until I passed another exit. The only resolution was to shift the car into neutral which slowed it down and then I was able to put the car into a narrow shoulder and put it in park then turned the car off right away. My family and I were almost killed because of this vehicle failure!
First, the air bag light for driver stays on, then cruise control quit working, now the horn quit working. I took it to a garage and was told it was a faulty clock spring. I looked up and see that other models of Kia's have been recalled for faulty clock springs; but not the Sedona. I believe this model should also be recalled as it is a safety hazard not to have a working air bag and horn. I was told by two different garages that it will cost $350 to replace the clock spring. I cannot afford to fix this so I will drive with no horn or air bag. If I should be injured or die in a crash due to either of these items not working I have instructed my wife and children to sue Kia for not recalling all the clock springs, when its obvious that more models have problems than what has been recalled.
We were driving interstate 80 westbound. As we were exiting a rest area entering the interstate the accelerator became stuck and the speed of the vehicle could not be controlled. We were reaching speeds upwards of 90-100 MPH. We couldn't get the van to slow down so we put the van in neutral to slow it down. The van finally slowed but because the rpms of the engine were so high and would not stop the engine made a screaming noise and the van finally stopped. We had it towed about 50 miles to the Kia dealer in des moines iowa and are waiting to see if there was a factory defect that caused the pedal to become stuck all the way to the floor with no release.. In the mean time it is feared that the engine is blown, making payments still and no vehicle or help from dealer at this time..
While driving on the interstate with cruise control activated the vehcile experianced an uncommanded deceleration with no response to pressing the gas pedal. With no left hand medium to pull over to, this left only the right medium as an alternative. Navigating to the right without acceleration made this extreamly dangerous in miami traffic. Once on the medium the vehicle was turned off and restarted, reactivating the system. Dealer indicates the throttle position sensor is intermittanly defective causing the throttle to default to idle mode and deactivating throttle commands. I am of the opinion this is an unsafe condition and the throttle should default to a manual input if the sensor becomes discrepant.
Tl contact owns a 2007 Kia Sedona. While driving approximately 30 MPH, the vehicle accelerated and became stuck at approximately 60 MPH. The contact placed both feet on the brake pedal in an attempt to stop the vehicle, but nothing happened. She then proceeded to kick the side of the accelerator pedal for approximately one minute before the pedal released. There was no crash. The dealer was notified and confirmed that the pedal sticks and will replace the accelerator pedal. The pedal is currently on order. The current mileage was 3,434 and failure mileage was 3,300. Updated 3/11/08 the consumer stated this defect happened twice. Updated 03/11/08
