Gas Recirculation Valve (egr Valve) problems of the 2005 Kia Motor Amanti

I purchased my kia from jd byrider in 2016 of July and I have had a real deal with this car. In the pass 4 years with this car I have poured more than $5,000 into this car into it. Every time you get this car fixed it has a new problem about 1 month later or the check engine light comes on. But recently my wife was driving her mother and my daughter around shopping about 10 miles in distance from the house the mall and driving store to store. It was 93 degrees outside and she had the a/c running and suddenly the car started to have sudden acceleration she tried to stop the car and it did not stop the engine keep revving up harder harder and harder. At this point she was able to turn back into the parking lot after getting off the main rode. This car is a danger to people driving it and others near this car should not be on the street I repeat this car should not be on the street. I am glad my family is safe but I will trading this car in soon and I hope the rip it up and tear it to pieces for parts because it could have ended my families life. For me and my other love ones to very see them again. Get this car off the rode please. This is the third time this has occurred I could't do anything because jd byrider sold me overpriced junk $12,000 worth of it and add the repairs on top. I refuse to keep driving this car or have my love ones drive that car.
