2014 BUICK LACROSSE Electronic Stability Control Esc Problems

WHILE DRIVING TO WORK GOING APPROXIMATELY 55MPH IN MY 2014 BUICK LACROSSE I LOST ALL POWER STEERING. THE STABILATRAC INDICATOR CAME ALONG WITH A SERVICE ABS BRAKE LIGHT. I WAS NOT ABLE TO SET CRUISE CONTROL AS WELL. I WAS ABLE TO MAKE IT TO WORK AND HAD TO HAVE THE VEHICLE TOWED FOR SAFETY REASONS. *TR

I WAS ON THE HIGHWAY ON THE INTERIOR LANE AT 75 MPH WHEN ALL THE SUDDEN I GOT A AUDIBLE AND VISUAL ALARM INDICATING STEERING FAILURE. I THEN GOT THE SAME FOR STABILTRAK FAILURE. THE STEERING ASSIST WAS OBVIOUSLY GONE IMMEDIATELY AND THE CAR STARTED FLOATING BACK AND FORTH. I HAD MY WIFE AND 92 YEAR OLD MOTHER-IN -LAW WITH ME AND IT WAS MISTING HEAVILY SO I CAREFULLY CONTINUED TO DRIVE AT A REDUCED SPEED. I TOOK THE CAR IN AND THEY SAID THE STEERING WAS NOT GETTING ELECTRICITY. ALSO, THEY SAID THE PASSENGER SIDE REAR WHEEL SENSOR WENT OUT WHICH CAUSED THE BACK AND FORTH MOTION. THE CAR DEALERSHIP WANTS TO CHARGE ME $3400 FOR THE REPAIRS. I SEE THAT THERE WERE RECALLS ON OTHER GM PRODUCTS FOR THE STEERING ON SIMILAR MODELS I.E. CADILLAC ETC. I FOUND SEVERAL INSTANCES ONLINE FOR BUICK LACROSSE BUT FOR SOME REASON...

CAR HAS AUTOSTOP. WHILE WAITING ON LIGHT AND WHEN IT CHANGED CAR STALLED LIKE IT DID NOT WANT TO START UP. IT MADE THE NOISE LIKE SOMEONE TURNED THE KEY WITH THE CAR STILL ON, BUT THIS IS A KEYLESS IGNITION. IT HAS DIED THIS SEVERAL TIMES AND I HAVE TAKEN IT TO BUICK DEALER AND THEY SAY NOTHING WRONG WITH IT, IT HAS DID IT TWICE MORE SINCE THEY CHECKED IT. LAST TIME I WAS AT A FOOD DRIVE THRU AND IT STALLED MADE NOISE THEN STARTED BACK UP. VEHICLE WAS STATIONARY. IT SEEMS LIKE THE AUTOSTOP GETS STUCK AND THEIR IS A DELAY STARTING BACK UP. THAT IS DANGEROUS WHEN TURNING AT A LIGHT. PLEASE INVESTIGATE . THANK YOU

MY WIFE WAS DRIVING OUR 2014 BUICK LACROSSE ON THE INTERSTATE AT ~65 MPH WHEN THE ELECTRICAL POWER STEERING SUDDENLY QUIT WORKING- ALMOST CAUSING HER TO CRASH.
