2009 CADILLAC DTS Steering Problems

VEHICLE WOULD NOT START WHEN ATVTRAIN STATION. HAD TO LEAVE OVERNIGHT AND HAD IT TROUBLESHOT IN AM. A FAULTY FUEL PUMP RELAY WAS THE SUPPOSED CAUSE. CHANGED THE RELAY ON A WEDNESDAY MORNING AND CAR WAS GOOD TILL SATURDAY AFTERNOON WHEN IT STALLED OUT IN THE MIDDLE OF ROUTE 9 IN HEAVY TRAFFIC. AT THE TIME MY WIFE AND GRANDSON WERE IN THE CAR. I HAD TO PUSH THE VEHICLE OFF THE ROAD LUCKILY INTO A STRIP MALL WITH AN AUTO PARTS STORE. REMOVED GRANDSON AND CAR SEAT FROM VEHICLE TO ACCESS THE RELAY IN REAR CIRCUIT BOARD. VERY HOT. I WENT IN AND GOT NEW RELAY AND HAD TO CHANGE IT IN THE PARKING LOT. WENT STRAIGHT HOME TO DROP OFF WIFE AND GRANDSON. WENT BACK OUT TO TEST DRIVE AND SEE IF PROBLEM WAS FIXED. WORKED FOR A LITTLE WHILE AND STALLED OUT AGAIN. AGAIN RELAY BURNING HOT....

MY 2009 CADILLAC DTS RECENTLY HAD A PROBLEM WITH THE STEERING, IT WAS STEERING HARD WHEN MAKING RIGHT OR LEFT TURNS AND EVENTUALLY BEGAN MAKING NOISES. I TOOK IT TO MY GM DEALER AND THEY CHECKED THE HOSES AND FLUID RECEPTACLE. ALL THEY FOUND WAS THE RECEPTACLE WAS LOW ON POWER STEERING FLUID AND I PICKED UP A BOTTLE AT AN AUTO PARTS STORE AND THEN MY STEERING WAS OK. SEVERAL WEEKS LATER MY STEERING GOT VERY HARD AND I HAD TROUBLE STEERING IT SO I STOPPED AND ADDED MORE FLUID. I RETURNED TO THE DEALER AND WAS TOLD MY POWER STEERING LINE WAS LEAKING AT ONE END WHERE IT WAS ATTACHED TO SOME METAL. MY COST WAS $402 TO REPLACE THE ONE HOSE. THIS LEAKY HOSE MADE MY CAR VERY HARD TO STEER AND I CAN'T IMAGINE WHY A STRONG HOSE LIKE THIS ONE WOULD EVER LEAK ESPECIALLY ON...

LOST OF POWER STEERING DURING LEFT TURN FROM STOP SIGN. *TR
