Hello my name is Kia Bennett i have 2009 impala. I keep receiving SERVICE REACTION CONTROL message and ENGINE POWER REDUCED. My car completely shut off on a busy highway speeds at 70 mph. Received message SERVICE THROTTLE STARTER DISABLED. Ive had it looked at and different things fixed and replaced on the car. I see other people have had the same problem. I could've been a deadly accident AGAIN. The first time was a few weeks ago. I had it fixed and it ran well for about a week and a half and then the messages popped up again and it shut down again today on the freeway. Why has there not been a recall or an offering to fix it? Please respond add this is my only means of transportation for myself and three children and these repairs are costly.
