This is the second time I report this unintended acceleration, last month happened on May 4, I documented in my previous complaint, they returned the car 5-21-14 they didn't find anything, on June 6 again the car accelerated when I was stepped on the brake and ready to put it in park, they told me to take the car to another dealer until now don't hear from them, called Kia in California left messages no call back, today a got a hold with another person jenny, and she repeat like a broken record we cannot duplicate the problem but they still keep the car for a long time, I have a case # [xxx] the NHTSA should investigate this, like I explained to this lady engineers should look at this situation not the mechanic, is something to do with the computer, they just follow instructions and their machine tell them nothing is wrong, like I mentioned before in my other complaint this one is the fourth time that happened, what are we waiting that some people got kill to investigate, look at the problems that Toyota and general motor had, they wait until people died then start doing something, thank you to this site that we could voice our concerns.

Vehicle was driven a mile to a commuter rail station for a drop off and back home. Nothing unusual was noted during the short trip nor had any problems been observed in the days leading up to the incident. Shortly after parking the vehicle on the 5th floor of the parking garage and entering the residence, the complex fire alarms actuated and all residents were advised to evacuate without entering the community parking garage. Shortly thereafter, I was notified by the complex manager via my cell phone that my car was on fire in the garage. The entire front of the vehicle was burned and was declared a total loss by the insurance company. (allstate). The entire car would have burned if it hadn't been parked directly under a sprinkler head in the garage plus a speedy response from the fire department. An independent fire origin investigator was hired by the insurance company. His professional opinion was the fire started at the radiator fan assembly.

Sudden acceleration! happened approximately 6 months ago and again on May 10th. Going slowly towards a stop sign while braking to stop, the car suddenly accelerates and lunges forward. Stepped on the brake but car keeps going. Put shift lever in neutral with engine racing and after about 2 seconds the engine slowly drops to idle. No accidents caused because no one was in front of me. Very dangerous situation! took car to the dealer on May 15th and they could find no codes present and said the vehicle was operating as designed.
