ON SEVERAL OCCASIONS WHILE DRIVING WITH THE CRUISE CONTROL ENGAGED, AS I APPROACH A VEHICLE FROM THE REAR THAT IS GOING SLOWER, THE AUTOMATIC BRAKING SYSTEM ENGAGES AND DISPLAYS A MESSAGE SIMILAR TO THIS! " SHUT DOWN ENGINE IMMEDIATELY, SERVICE REQUIRED." THE FIRST TIME IT HAPPENED, I DID SO, AND HAD THE CAR TOWED TO A DEALERSHIP. THEY SAID THEY COULD NOT FIND ANYTHING WRONG. I'VE REPORTED THIS PROBLEM TO THE DEALERSHIP THAT REGULARLY SERVICES THE CAR, AND THEY SAY THEY CAN'T RECREATE THE CONDITION. IT APPEARS TO BE A SOFTWARE PROBLEM. ON SEVERAL OCCASIONS RECENTLY WHEN THIS CONDITION APPEARS, THE ABILITY TO RESUME ACCELERATION IS LOST MOMENTARILY, AND THE CAR SLOWS DOWN DRASTICALLY. IT SUDDENLY RELENTS, AND RESUMES TRAVELLING AT THE PRESET SPEED. THIS ALWAYS HAPPENS ON MAJOR HIGHWAYS WHERE CRUISE CONTROL IS ENGAGED. I'M VERY CONCERNED THAT ONE DAY THE WARNING MAY LEAD TO A CATASROPHIC FAILURE OF THE ENGINE
