general problems of the 2001 Toyota 4Runner

I was driving a 2001 Toyota 4runner on a 2 lane mountain highway a couple years ago. Wintertime, wet road. Going 50 mph around a wide right turn, the anti-skid brake system suddenly screeched at me, and apparently applied the brakes on the left side of the car, causing it to swerve left towards the opposing lane of traffic. I managed to correct, and avoid an accident. I went with my friend whose car it was to the dealer later and described the occurrence. The dealer claimed that one of the tires was low. I never trust anti-skid brake systems since this occurrence. This kind of response is completely unacceptable. That same car also had a firmware glitch in the 4 wheel system that would cause the 4 wheel not to be disabled until you pulled over and shut off the engine for a bit, on an unfrequented basis.
