I was driving down the road about 1 mike from my house. The road is a country road and is straight. I wasn't distracted or speeding. It happened so fast but I think I may have hit a slight bump on the right hand shoulder of the road and then the car started fish tailing and then went off the road and was stopped when it hit a dirt driveway. I had no control of the car and the brakes failed to stop the car. The car was totaled with only 36000 miles on it even though I luckily just sideswiped a tree. The car always seemed hard to steer as if the steering was loose and you really had to pay attention and keep both hands on the steering wheel. The car was my elderly in-laws who bought it brand new in 2007. They both passed away in November 2018 and then I inherited it and had just recently started driving it. The air bags did not deploy.
