2008 Chevrolet Malibu stability control problems

My sister an I was on a flight from los angeles, ca into dallas, tx at the airport we rented a car from national car rental to go onto shreveport. La to see our sister who was in her last days with her fight with cancer. We're on I-20 north driving along then all of a sudden the car steering went out of control, speeding going very fast I could not stop, the went over into the medin of I-20 steal travel fast went all the way over to the other side south I-20 still could not stop no brake we hit a car on the other…

Car states engine power reduce on my car, will be driving and the codes will come on, speed reduced, traction turned off, acceleration is slow. No warning this is going to happen, can happen while driving high speeds or regulars speeds. Has happened or city streets and highway. If you fix one thing code some back saying it's another thing. Don't feel safe in driving the car, never know when this mode will come on.
