WHILE DRIVING 70 MPH ON THE HIGHWAY MY 2011 KIA OPTIMA ENGINE SHUT DOWN AND WOULD NOT ACCELERATE AND THE BRAKES WOULD NOT FUNCTION. LUCKILY, I SAFELY MADE IT TO THE FAR SHOULDER OF THE HIGHWAY ONLY TO FIND THAT MY CAR WAS SMOKING AND SMELLED LIKE SOMETHING WAS BURNING. HAD TO GET THE CAR TOWED TO THE DEALERSHIP AND THEY INFORMED THE ENGINE NEEDS TO BE REPLACED AND THE STARTER IS ALSO FRIED. I HAVE SEEN FOUR COMPLAINTS SO FAR OF 2011 KIA OPTIMA'S WITH THE SAME ISSUE AND AM SURE I WILL FIND MORE. THAT SEEMS LIKE TOO MUCH OF A COINCIDENCE THAT IT HAPPENS SO FREQUENTLY WITH THESE MODELS AND THERE ISN'T ANY SORT OF RECALL. NO BREAKS AT 70 MPH IS PRETTY DANGEROUS. I HAVE CONTACTED MY ATTORNEY AND HOPE THIS MANUFACTURER WILL DO THE RIGHT THING.
