Open the full vehicle complaint log (all categories)I WAS TRAVELING 25 MILES AN HOUR ON A ROAD AND MY BRAKES LOCKED UP AT A RED LIGHT. THIS HAPPEN ONCE BEFORE, I THOUGHT IT WAS BECAUSE OF THE RAIN. LUCKY THEY CAR IN FRONT OF US RAN THE RED LIGHT TO KEEP US FROM HITTING THEM. BUT ON THE 8TH OF THIS MONTH MY SISTER USED MY CAR FOR HER DRIVERS TEST, SHE TRIED TO USE THE EMERGENCY BRAKE FOR HER TEST. THE MAN TESTING HER SAID IT DOES NOT WORK. I DO NOT HAVE THE FUNDS TO FIX THIS. I FEEL THE DEALERSHIP I BOUGHT IT FROM SHOULD FIX IT OR REPLACE THE CAR. THIS COULD CAUSE A WRECK THAT COULD KILL OUR FAMILY. *TR
WHILE BACKING OUT OF A PARKING SPACE, MY CAR SUDDENLY ACCELERATED WHILE IN REVERSE GEAR. I PUT THE BRAKES ON BUT TO NO AVAIL. I HAD NO CONTROL OF THE SPEED. THIS IS ALL HAPPENING GOING IN REVERSE. I CRASHED INTO THE BUILDING NEXT TO THE PARKING LOT. THE FLOOR MAT WAS SEATED PROPERLY AND YES MY FOOT WAS ON THE BRAKE PEDAL. *TR
BOUGHT A 2007 KIA OPTIMA IN JULY 2010, AFTER 3 MONTHS HAD TO HAVE BRAKES AND ROTORS REPLACED. NOW ONLY A MONTH LATER THE BRAKES ARE BAD AGAIN. I HAVE TO TAKE IT TO THE SHOP. THE BACK DRIVER SIDE BRAKES ARE GRINDING. THE CAR CONTINUES TO SQUEAL. I TALKED TO THE DEALERSHIP WHERE I BOUGHT THE CAR THIS IS NOT COVERED UNDER WARRANTY. HOWEVER WHEN I BOUGHT THE CAR THEY SAID THERE WAS MORE THAN 50% BRAKE PADS LEFT. WHEN I CHANGED THEM THE FIRST TIME THEY WERE COMPLETELY GONE IN THE BACK ON THE DRIVERS SIDE. I DO NOT FEEL THAT I SHOULD HAVE TO BE REPLACING THE BRAKES AGAIN, JUST ONE MONTH LATER. SOMETHING IS WRONG WITH THAT. I AM NOT HAPPY WITH MY CAR OR THE DEALERSHIP AT THE MOMENT. *TR
