2008 VOLVO XC90 Steering Problems

I WAS DRIVING DOWN THE HIGHWAY AND MY VEHICLE COMPLETELY SHUT DOWN AND THE STEERING LOCKED. I WAS ABLE TO PUT ON THE EMERGENCY SIGNALS AND THE BIG RIGS BEHIND ME BLEW THEIR HORNS. THEY WERE GETTING CLOSER TO ME BECAUSE I WAS DECELERATING AT A RATE THAT WOULD HAVE RESULTED IN A COLISSION. FORTUNATELY I WAS ABLE TO COAST INTO AN EMERGENCY LANE WHILE THEY WENT WHIPPING PAST ME. THE VOLVO SERVICE MANAGER STATED THAT HE HAD HEARD OF A SIMILAR SITUATION BEFORE. IN AN EMAIL TO ME HE STATED THAT "THE PRESSURE SENSOR WAS GIVING A FAULTS READING, OF EXCESSIVE FUEL PRESSURE. WHEN THE PEM SAW THE FAULTS READING, IT CUT THE FUEL TO THE ENGINE AS IT THOUGHT IT WAS WAY OVER PRESSURIZED." I FEEL VERY FORTUNATE THAT NOBODY WAS SEVERALLY INJURED OR KILLED.
