“I was driving 35mph down my road in my Impala. The engine light came on and a traction control/reduced engine power message came on. The car suddenly slowed to 20mpg and I almost got rear ended. I was told by a mechanic that this is a hugely popular issue with this car and chevy refuses to fix it. This is dangerous as I almost lost control when this happened.”
