2015 Audi A4 Steering

I NOTICED THE STEERING STARTED GETTING HARD TO TURN. I TOOK TO AUDI DEALER THEY SAID IT WAS FINE. I SAID NOT I KNOW MY CAR. ON THE HIGHWAY 2 WEEKS LATER ENTERING A CURVE AT HIGH MPH THE CAR WOULDN'T TURN. I TAPPED BRAKES SEVERAL TIMES AND FINALLY WITH 2 HANDS I COULD TURN AROUND CURVE. VERY SCARY AND BARELY MADE TURN. I PROCEEDED TO HOME BUT AT A TURN I STARTED THE TURN AND THE STEERING AGAIN STIFFENED SO HARD IT SENT ME TOWARDS THE CROSSWALK AND LUCKILY THE BRAKES STOPPED ME INCHES FROM HITTING A BOY ON HIS BIKE. I KEPT HITTING BRAKES AND FINALLY THE WHEEL RELEASED THE TENSION. I DROVE HOME AND LEFT IT UNTIL I GOT AN APPOINTMENT AT AUDI DEALER. I CAREFULLY DROVE IT DOWN TO DEALER AND HALF THE DRIVE IT WAS FINE AND HALF THE DRIVE THE CAR I BELIEVE ELECTRONICALLY TIGHTENED DOWN THE WHEEL SO IT WAS EXTREMELY DIFFICULT TO TURN. THE CAR IS AT DEALER BUT THEY STILL HAVEN'T FIGURED OUT ISSUE. I LOOKED ONLINE FOR THAT SAME MODEL AND YEAR AND HAVE FOUND SEVERAL ISSUES EXACTLY DESCRIBED LIKE MINE. IT OCCURS IN MOTION WHEN DRIVING AND TURNING. I FIND THIS EXTREMELY DANGEROUS AND AM WORRIED TO DRIVE UNTIL ISSUE FOUND. I BELIEVE IT IS A COMPUTER OR ELECTRICAL TYPE ISSUE BASED UPON MY EXPERIENCE WHERE IT ISN'T HAPPENING ALL THE TIME BUT I AM NOT A MECHANIC. I FIND THIS ISSUE REALLY TROUBLING. I COULD HAVE EASILY BEEN SERIOUSLY INJURED OR KILLED AND I AM STILL SHAKING FROM HOW CLOSE I CAME TO RUNNING OVER A LITTLE BOY ON HIS BICYCLE. WITH OTHER PEOPLE SAYING THE SAME ISSUE AND DESCRIBING IT SIMILARLY I THINK THIS IS A PROBLEM WITH THIS VEHICLE MODEL.

STEERING SHAFT IS FAULTY. WHEN DRIVING THIS CAR, ESPECIALLY AT HIGH SPEEDS, THE STEERING IS EXTREMELY UNPREDICTABLE. AT LOWER SPEEDS, THE STEERING IS NOTCHY, YOU CAN'T SEEM TO FIND "CENTER" AND CONSTANTLY HAVE TO ADJUST THE STEERING WHEEL TO REMAIN STRAIGHT ON THE ROAD. THIS HAPPENS WHILE MOVING, ON CITY STREETS AND HIGHWAYS.

STEERING IS LOCKING UP/BECOMES HARD TO TURN WHILE DRIVING. THIS ALMOST CAUSE ME TO CRASH AS I COULD NOT TURN EASILY IN AN INTERSECTION. I RECENTLY HAD THE CAR SERVICED (IN THE LAST MONTH) REGARDING A HEATER RECALL. ABOUT 3 WEEKS LATER THIS PROBLEM STARTED TO OCCUR OUT OF THE BLUE. NO WARNING LIGHTS HAVE COME ON.
