Filed Oct 16, 2014 · Engine · 65,000 miles · SC

Driving down the road and lost all power. We had to pull off the side of the road, turn the van off and wait a few minutes. When we started it back up it ran okay but this happened several times (dates unknown other then aug 7,2014) driving down a busy road and having loss of power could have been very dangerous. It is the throttle position sensor that is causing this problem.

In 18 months my 2008 kia sedona has continuous electrical problems, with this complaint focusing on the fact my vehicle has blown the 200 amp main fuse 4 times in 18 months, including while driving the vehicle 2 of the 4 times, causing complete loss of power and a safety issue as both times it happen while highway driving, with the dealer not being to determine the cause of the problem each and every time. They replace the fuse, run tests, and give the car back, at which point anywhere from 10 days to 6 months the fuse blows again. Note this same vehicle was in and out of the dealer repair for a check engine light they were unable to turn off for more than 48 hours at a time (computer reset) for 9 months which I sued under lemon law for.

While driving 70 MPH down freeway kia suddenly lost power and would not accelerate had to maneuver across 6 lanes of traffic to get to shoulder. Once I turned van off and restarted, I could once again accelerate. The failure occurred 3 more times within a 5 mile stretch. Finally made it to a gas station where we called for roadside assistance, I had 3 babies in carseats in van at time of failure this could have been a huge tragedy if traffic was any worse than it was. Van is at dealer now waiting for service.

Acceleration failure gas pedal un-responsive has occurred on multiple occasions over the past few months. Mileage at onset approx. 28,000, current mileage 37,000. 1- first occurrence june 13th 2010 traveling on freeway when loss of acceleration caused vehicle to become dangerous as navigation off the highway was reliant on drifting to shoulder with no power; once off the road turning off and restarting the engine caused the gas pedal to reengage - however during the 4 hour trip the issue repeated 7 times with the most dangerous occurrence in an area of construction where no shoulder was available to pull off. As this issue occurred on a sunday, taking the vehicle in for service was not an option until monday, and during the waiting period the check engine light was no longer illuminated and therefore the code for investigation unavailable. 2-issue occurred again on saturday, july 30, 2010 while traveling on the highway after one hour of travel and repeated every 10-15 miles; on this date turning off and restarting the engine multiple times was required to regain gas pedal control. Serious safety issue when the loss of power was experienced while passing traffic and navigation off the road from the passing lane required returning to the right lane in high traffic with no ability to adjust speed. On the 2.5 hour return commute the issue did not resurface. 3- the issue again repeated on sunday, august 1, 2010 while traveling on arterial roads, during the 45 minute commute the issue repeated 3 times at varying speeds from 45 - 60 MPH.

We rented a 2008 kia sedona van with the 3.8l engine and it lost power in the middle of the highway at speeds of 65-70mph. The engine did not die, but the check engine and ESC warning lights came on and there was no power being transferred to the transaxle. On the first van the incident occurred after driving only 50 miles, the replacement van was driven 1,286 before it too did the same thing. We informed advantage car rental that it appears to be a systematic problem with that make and model.
