2006 Kia Sedona: sudden loss of power

Filed Oct 11, 2014 · Acceleration, Driver assistance · 67,000 miles · VA

I was leaving my house and had just driven a short distance when the check engine light and the ESC off came on as the car slowed to almost a stop. I pressed on the accelerator and nothing happened. I got out of the car and raised the hood and the engine was idling roughly. I turned the car off and on several times but nothing chaged; it wouldn't accelerate and the warning lights stayed on. The ESC off light eventually went out and the check engine light stayed on but I was able to drive it again. I took it to a mechanic who lubricated a throttle cable after checking the codes. It worked for a few weeks after that but the ESC off light came on again intermittently after that. I am afraid of losing power when I am in heavy traffic, at an intersection, merging, or anywhere I will be in danger if I cannot move out of the way of oncoming traffic.

Driving approx 35 MPH when kia van lost power and had to coast to side of road. No forward movement with gas pedal pressed down. Sat for 10 minutes and was able to drive at normal speed for about 30 minutes when I slowed down to turn corner, lost power again. Coasted to side of road, sat for another 10/15 minutes then drove to auto mechanic. Replaced throttle position sensor for 2nd time. Vehicle computer also reset. Serious safety risk as vehicle loses power in middle of traffic without warning and very limited time to make decision where to coast to as you do not have any driving control.

Vehicle has been suffering from constant power loss with ESC light illuminated. Now it suddenly accelerates with the light lightest touch on pedal, lurching as it accelerates. It happens especially often when engine is under stress, such as climbing up a hill. I was parking in garage when is rapidly accelerated and my side bumper in front grazed garage door sidewall. It has also happened in reverse with rear side bumper nicking same spot on garage. This vehicle is a safety nightmare. Fault codes p2135 and p2106 often appear.

The vehicle will lose power. The engine will continue running, but only at idol speed. This event can happen at any time. My wife was driving our kia at the time this event happened. The check engine light and the ESC off light came on and the van had no power. After shutting the van off and restarting she was able to drive home with only the check engine light on. I pulled the neg. Battery cable and reset the ECM. I drove the van for 200 miles without incident. The next morning the van started normally, but within a minute both lights were on and the engine would not respond to any throttle input. The codes pulled from the computer are p1295, p2106, and p2135. After looking on google, this is a chronic problem plaguing kia and hyundai vehicles. According to what I've read, it can happen at any time, on any model year. Nobody has been able to isolate the cause, except to replace the ECM, and replace the throttle body. It is only a matter of time until this happens to somebody in heavy traffic at highway speed.
