IN APRIL OF 2015 WHILE DRIVING ON THE INTERSTATE SURROUNDED BY OTHER VEHICLES THE ELECTRIC POWER STEERING SENSOR FAILED. THE POWER STEERING WARNING FLASHED ON THE IN DASH INFORMATION CENTER AND SEARING THE VEHICLE WAS NEARLY IMPOSSIBLE. I WAS FORTUNATELY ABLE JUST AVOID SEVERAL COLLISIONS WITH OTHER VEHICLES. THE FOLLOWING DAY I BROUGHT THE VEHICLE TO THE DEALERSHIP TO HAVE THE SENSOR REPLACED. THIS WAS NOT COVERED UNDER ANY WARRANTY OR RECALL AND I COVERED THE COST OF THIS. LESS THAN TWO YEARS LATER THIS SAME ISSUE HAS OCCURRED AGAIN. I WAS DRIVING ON BACK ROADS THAT TURNED IN SEVERAL DIRECTIONS. GOING AROUND ONE CORNER, FOLLOWING THE SPEED LIMIT THE POWER STEERING FAILED. I WAS UNABLE TO CONTROL THE VEHICLE AND WENT INTO DITCH ON THE OPPOSITE SIDE OF THE ROAD. LUCKILY THERE WERE NO OTHER VEHICLES INVOLVED. I CONTACTED CHEVY AND WAS TOLD THAT THEY WILL NOT TO ANYTHING TO CORRECT THE ISSUE, REFUSED TO ALLOW ME TO SPEAK WITH ANYONE ELSE AND HUNG UP ON ME. THEIR SUGGESTION WAS TO CONTACT THE DEALERSHIP THAT REPLACED IT TO SEE IF THE WOULD GIVE ME A DISCOUNT FOR THE DEFECTIVE PART AND CLAIMED IT WAS NORMAL WEAR AND TEAR. WITH AN ELECTRIC POWER STEERING THERE IS MINIMAL WEAR AS TO IT IS ALL ELECTRIC COMPONENTS AND THEY SHOULD NOT HAVE MALFUNCTION AFTER BEING REPLACED LESS THAN TWO YEARS AGO. THIS IS AN ONGOING PROBLEM FOR THIS MAKE, MODEL AND YEAR AND IS A SERIOUS SAFETY CONCERN.
