“I've had the brakes replaced because I thought they were an issue I was having with my ABS. But my car will randomly lock its brakes as I'm driving, no matter what speed. I'm scared to drive it. It also almost loses all power after breaking but then speeds up on its own making it almost impossible to slow down or brake.”

“THE FIRST THING TO GO WRONG WAS THE POWER WINDOWS DON'T WORK PROPERLY IN THE WINTER, NOW THE AIR CONDITIONER ONLY BLOWS COLD AIR INTERMITTENTLY, AND THE MOST RECENT PROBLEM IS THE HEADLIGHTS WON'T WORK AT ALL, I CALLED THE LOCAL SERVICE CENTER AND THEY SAID THAT THE ELECTRICAL RECALLS WERE VIN SPECIFIC, EVEN THO I HAD THE CORRECT MAKE MODEL AND YEAR MY VIN DID NOT QUALIFY FOR THE RECALL! I'M VERY UPSET THAT THEY CAN BE VIN SPECIFIC BUT I'M HAVING ALL THE ISSUES ON THE RECALLS!! I CAN NO LONGER DRIVE MY VEHICLE IF IT IS RAINING, FOGGY, OR DARK BECAUSE I HAVE NO HEADLIGHTS!!! I ALSO LOST CONTROL OF MY CAR IN THE RAIN AND THINK IT HAS TO DO WITH THE STABILITRAK, THE LIGHT HAS BEEN ON FOR A WHILE, LUCKILY I STOPPED MY CAR BEFORE I CRASHED INTO ANYTHING”
