2001 Mercedes-Benz ML320 brakes problems

Safety system failure, including braking assist, seat belts, air bags and tel-aide due to computer chip failure. Caused two accidents after which customer paid to have vehicle reviewed bumper to bumper and the failing chip was replaced. During this time, the dash warning lights did not illuminate to warn of the failure which the vehicle computer documented 15 times in a six-month period (between the two accidents). Approximately eight months later, the warning light on the dash illuminated again.

My dad was driving the car and we had just come to a stop at an intersection. When the light turned green, he accelerated and just as we crossed the intersection, the brakes locked up. I thought my dad had slammed on the brakes, but he had his foot on the gas pedal. It was as if the car had a mind of its own and started to brake on its own volition---even though we didn't want it to. There was a loud screeching sound and a few seconds later you can smell the stench of burning rubber.
