2008 LEXUS RX HYBRID Steering Problems

WHILE DRIVING ON A CITY STREET, I LOST POWER STEERING COMPLETELY. P/S AND BRAKE DASH LIGHTS CAME ON ALONG WITH "SERVICE HYBRID SYSTEM" AND "SERVICE AWD SYSTEM". AFTER A FEW MORE MILES THE VEHICLE LOST COMPLETE PROPULSION POWER AND I WAS FORCED TO PULL OUT OF TRAFFIC. I TURNED OFF THE VEHICLE AND IT STARTED FINE WITH NO POWER STEERING. I MADE THE NEXT MILE TO THE DEALERSHIP. THEY REPLACED THE ECU THAT HAD SHORTED OUT DUE TO A BAD STEERING RACK. I AM NOT SURE WHY THE ELECTRONIC STEERING MECHANISM WOULD CAUSE COMPLETE LOSS OF POWER FROM THE ENGINE/HYBRID SYSTEM?

POWER STEERING CAN HARDLY MOVE

WHILE DRIVING BACK HOME FROM A ROAD TRIP I NOTICED THAT THE STEERING WHEEL STARTED TO SHAKE AND I HEARD A KNOCKING NOISE. I WAS DRIVING APPROXIMATELY 50-60MPH. I SLOWED DOWN AND TRIED TO PULL OVER BUT BEFORE I COULD DO SO, MY FRONT PASSENGER WHEEL (THE ENTIRE RIM AND TIRE) BROKE OFF OF THE CAR. LUCKILY I HAD ENOUGH MOMENTUM AND WAS ABLE TO PULL THE CAR OVER SAFELY TO THE GRASSY SHOULDER. I PURCHASED MY CAR USED BACK IN 2012 AND IT ONLY HAD 28,000 MILES ON IT. THIS VEHICLE HAS ALWAYS BEEN SERVICED AT A LEXUS DEALERSHIP (BY THE PREVIOUS OWNERS AND BY MYSELF SINCE I PURCHASED THE VEHICLE). I DO NOT UNDERSTAND HOW ANYTHING LIKE THIS COULD HAVE HAPPENED. LUCKILY NO ONE IN MY VEHICLE WAS INJURED AND THAT THE OTHER DRIVERS ON THE ROAD WERE ABLE TO MANEUVER AROUND MY CAR AND THE TIRE THAT...

WHILE TURNING INTO PARKING LOT FROM ROAD BUMPED THE RIGHT FRONT TIRE INTO CURB AT APPROX 4 MPH. POWER STEERING IMMEDIATELY CEASED TO FUNCTION. TOLD BY TOYOTA MECHANIC THAT A HIGH VOLTAGE POWER SPIKE DESTROYED THE POWER STEERING COMPUTER. PAID $1050 FOR REPLACEMENT OF POWER STEERING COMPUTER. DOES THIS MEAN A POTHOLE CAN ALSO FRY THE P/S COMPUTER. *TR

I DRIVE A 2008 LEXUS RX400H. I EXPERIENCED A SERIOUS ELECTRIC POWER STEERING FAILURE, WHICH CAUSED ME TO LOOSE CONTROL OF THE CAR WHILE DRIVING. ON OCT 15, 2009, I DROVE MY CAR ON THE FREEWAY WITHOUT INCIDENT. LATER THAT DAY, I PARKED MY LEXUS RX VEHICLE, AND IN DOING SO I TURNED THE STEERING WHEEL TO THE RIGHT "LOCK' POSITION. WHEN I RETURNED TO THE CAR I MADE A HARD LEFT U-TURN TO EXIT THE PARKING AREA. AS SOON AS I ACCELERATED AND TRIED TO TURN THE WHEEL BACK TOWARDS THE RIGHT TO STEER, I REALIZED MY POWER STEERING HAD FAILED COMPLETELY, AND I COULD BARELY CONTROL THE CAR. AFTER STRUGGLING WITH THE STEERING FOR SEVERAL HUNDRED YARDS, I WAS FINALLY ABLE TO PARK THE CAR AT THE SIDE OF THE ROAD. THE INCIDENT OCCURRED IN THE EVENING AND THE VEHICLE WAS TOWED TO THE CLOSEST LEXUS DEALERSHIP THE...
