I was driving my car and suddenly it flashed across the screen service stabilitrak, then service traction control system, then reduced engine speed. This caused my vehicle to slow way down out of no where from 70 to less than 30, and made steering near impossible. I have my two children I drove around and I'm afraid to even drive because if there's an accident with them in the car because my cars slowing unexpectedly someone will be paying for this. This is a huge safety issue and I see all over it is and it needs to be fixed!.

This is the second incident we have had with our 2008 Chevrolet Impala where this problem has occurred. The most recent incident was on Wednesday may 21st, around 730 pm. My wife was driving on a road with a posted speed limit of 45 miles per hour, she said she was going about 48 when the traction control light came on, and the messaging system indicated "reduced engine power. " when this happens the vehicle slows rather rapidly, and then it is impossible to accelerate beyond about 30 miles per hour or so. Due to the rapid decline in speed and the fact that this occurs without warning, I believe this should be an immediately acted upon problem. I contacted gm only to be told that I have to take it to get it looked at by one of their local dealerships, and pay for that diagnostic. In my online research I have discovered many, probably in the hundreds, who've experienced this identical issue. Some of which have take their car to gm who has concluded according to post of experiences on edmunds that they were unable to determine the source of the problem or repair it. This is a problem that require immediate attention. I can't imagine how differently this could have gone should my wife have been going 75 mph on interstate 80. We live along I-80 and travel it frequently. However as a result of this problem we are essenitally unable to trust our vehicle beyond about 50 miles per hour.
