I WAS DRIVING CAR AND A WARNING LIGHT SHOWED ABS, STEERING, SUSPENSION MALFUNCTION, REFER TO OPERATORS MANUAL. APPROXIMATELY 3 MINUTES AFTER THE LIGHT SHOWED, I PUT MY FOOT ON THE BRAKE, THE CARS BRAKES LOCKED UP, THE STEERING WOULD NOT WORK AND THE CAR SWERVED ACROSS THE ROAD INTO ONCOMING TRAFFIC AND I ENDED UP IN A CRASH THAT COULD HAVE BEEN FATAL, BOTH AIRBAGS DEPLOYED. EVEN THOUGH THE CAR IS COMPLETELY DESTROYED AFTER HITTING SEVERAL OBJECTS INCLUDING A TREE, WE ALL WALKED OUT WITHOUT A SCRATCH, HOWEVER HAD THIS HAPPENED AT A SPEED HIGHER THAN 30 MPH I BELIEVE WE WOULD HAVE ALL DIED. THE CAR LOST ALL FUNCTIONALITY OF BRAKES AND STEERING, THE BRAKES APPEARED TO STAY ON AND LOCKED EVEN WHEN MY FOOT WAS NOT ON THEM. I HAVE DRIVEN MERCEDES FOR 30 YEARS AND HAVE NEVER EXPERIENCED THIS TYPE OF PROBLEM EVER. ON THE GOOD SIDE ALL SAFETY FEATURES WORKED, THE AIR BAGS, THE BODY ALTHOUGH ENDING UP AT THE WINDSCREEN FROM THE FRONTAL CRASH DID NOT SMASH OR POP WINDSCREEN OUT, THE ENGINE DID
