Every 6 months the engine light and ecs off lights come on and the car loses power intermittently. This is dangerous when it happens on the freeway. I bought the car from carmax in July 2014. By November, it started to have the issue, it progressed at I checked it on the internet and saw a recall and brought it in to city Kia in orlando. The mechanic could not find an issue why the engine light was on and there was no clear code. However, when he replaced the recall lamp switch part it went away until now (Oct 2015). It is clear to me that there is an issue with the electrical system that can cause the loss of power. There are numerous comments from others with the same issue and the same symptoms. I expect carmax and Kia understand there is an issue. I bought the car with 32K miles on it from carmax and it already had 2 previous owners. The average Kia mechanic seems incapable of diagnosing and resolving this issue. They will just change out parts every 6 months and hopefully reset the electronics somehow. I am a licensed mechanical engineer and safety engineer working in the ride industry for 30 years. I believe this is a safety issue and I would like Kia to either fix it or take my car back or carmax to take the car back. The loss of power can occur when you start or when you are driving. The engine light and ecs light come on and always accompany this issue. Typical posts on internet Jun 30, 2014 - cheektowaga, NY - power train TL* the contact owns a 2008 Kia Sorento.

The contact owns a 2008 Kia Sorento. While driving at approximately 55 mph, the vehicle decelerated to 20 mph without the brake pedal being depressed. The sec and the check engine warning indicators illuminated. The failure recurred numerous times. The vehicle was taken to a dealer, where it was diagnosed that the throttle position sensor failed and needed to be replaced. The vehicle was repaired but the failure recurred. The manufacturer was not made aware of the failure. The failure mileage was approximately 80,000.

We were driving on a busy freeway on the way to work, the steering wheel started getting stiff so we slowed down and moved over to the far right. The car died but we were able to coast over out of traffic though the back of the car was still not out all the way due to the angle. We were not able to steer and straighten the car. The car would not start. We called roadside assistance and they were unable to jump the car. It was towed to a mechanic. The engine was locked. The mechanic said a screw broke off. There was an issue with the crankshaft. I had to get a new engine put in at the cost of just over $2400.

Two days ago the check engine light illuminated (and stayed on) with intermittent electronic stability control off light illuminated; vehicle acceleration became sluggish and sometimes unresponsive. Vehicle codes using obdii pocketscan showed active and stored codes of P2138 (accelerator), P2127 (accelerator) and P2106 (limp mode). I made an appointment to take it to the dealership on 09/25/13. On the day of appointment the check engine light was not illuminated, but the dealership found stored codes in the computer of P2138, P2127 and P2106. The dealership refused to fix the vehicle even though it was still under warranty because there was not an active code (check engine light) on at the time of the appointment and the part was functioning properly for the time being. When asked if it was their policy or Kia motors policy not to replace components that were failing, they stated it was Kia motors policy. This is the second time the accelerator assembly has failed in this vehicle. The last failure was 08/23/12 at 27,545 miles. A vast majority of the complaints with NHTSA for this make, model and year vehicle involve these codes and this component. A serious accident, or loss of life should never be the determining factor when making a decision that a manufacturer should take action to correct a faulty component; by then it is much too late.

Current and ongoing problems began just a few days after receiving a notice of recall from Kia regarding the faulty/defective brake light switch. The switch was faulty and there was a problem with no brake lights coming on upon braking as well as "ESC off" and "check engine" malfunction indicator lights appearing and staying on the instrument cluster. The vehicle was promptly taken to a Kia dealership where the recall service was performed. Replacement of a failed brake light switch under the recall campaign did not eliminate the problems/codes that began when the brake light switch failed. Shortly after the repair (less than a month afterward and very few miles driven) the "ESC off" and "check engine" malfunction indicator lights appeared, stayed, then came on and off intermittently with engine not going over past approximately 2,000 rpms resulting in unpredictable vehicle behavior especially when it comes to merging onto a highway/interstate or getting through an intersection. The vehicle was taken to the dealership where the service advisors gave assurances that the new brake light switch is not defective. The problem is that the service advisors/technicians could not specifically diagnose what needs replacement to ultimately solve this ongoing problem or if it is related to the failure of the of the brake light switch.

Driving on a surface street with a 40 mph speed limit. Car suddenly lost power and could not get speed above 20 mph. We were lucky that there wasn't much traffic about as this could definitely have caused an accident. When this happened both the ESC off light and the check engine light came on. We had to leave our car in Nevada and get a rental car to get home to Arizona, we have no idea when we will get our car fixed and back home. We were owners of a Kia rondo and the same thing happened to that vehicle too (no longer own that one). This vehicle needs to be recalled immediately and Kia needs to admit that there is something seriously wrong and that they will take responsibility for fixing it. Too many owners having exactly the same problem, we should not be ignored.

I was driving on an interstate with a speed limit of 65 mph when with no warning the "check engine" and "ESC off" lights came on simultaneously. At the same time, the engine lost power, causing my vehicle to suddenly decelerate and almost causing a collision both with the car behind me and with the cars merging over from an entrance ramp. Luckily, I was able to safely maintain control of my car and put on my hazard lights to warn other drivers of my much slower speed. Even depressing the gas pedal to the floor, I was unable to accelerate above 55 mph, and my speed going up hills was significantly slower. Once I was able to safely reach a shoulder with comfortable clearance, I pulled over and stopped the car for a few minutes. I restarted the car, both lights remained on, and I similarly was unable to accelerate the car appropriately, especially from a stop. I limped along with my hazard lights for the last few miles to work where I immediately began researching this issue only to find that this is far from an isolated incident. In fact, this problem seems to be pervasive in Kia of similar model year. There are scores of Kia owners who have experienced a similar series of events. The sudden and unexpected loss of power with absolutely no warning is highly dangerous in any situation, but especially so on the interstate when speed limits are so high. I was so lucky that the drivers around me and I were able to avoid an injury-causing crash. This issue needs to be investigated swiftly and thoroughly. Again, a simple search of this very website as well as other online car forums reveals a problem so widespread that it should warrant a recall by Kia.

2008 Kia Sorento start-up stalling temperamentally for three weeks. On 9/11/2012 the check engine light and ESC off light appeared, followed with a "putting" engine and limp mode. The car would not accelerate when foot applied to gas pedal. Kia dealership confirmed tps and brake sensor failure and electronic stability control needed reprogramming. (error codes read: P2135, P0638, and P2A00 or P2A03.) Kia published bulletin tsb 044: www.Kia-forums.com/attachments/Kia-carens-rondo-forum/5552D1272512047-engine-racing-stop-tsb-tps.pdf danger aspect: The car seemed drivable, however, the limp mode does not allow the car to accelerate to the speed limit or flow of traffic. Researched many similar complaints -- please issue an investigation for a recall.
