So I was going at 60 mph today, when I had to hit the brakes because the traffic was slowed. The minute I hit the brakes (and it wasn't a very sudden strong hit), the car started uncontrollably switching sides, and I nearly hit a concrete post, which would have certainly killed me. The steering wheel started moving sides all by itself very aggressively.
To make this clearer, when I hit the brakes, the car sort of started driving itself and slipping. Imagine if a drunk driver starts turning the while left and right very fast. It would have certainly injured others as well. The thing is that I changed the brakes about a month ago. Needless to say, I called a towing service, and the dealership will be inspecting it tomorrow.
Any ideas as to why this might have happened?
