Open the full vehicle complaint log (all categories)UPON PUTTING MY CAR IN REVERSE WITH MY FOOT ON THE BREAK, THE VEHICLE ACCELERATES TO THE POINT I HAVE TO SMASH THE BREAK TO THE FLOOR. THIS HAS HAPPENED SEVERAL TIMES WHILE PUTTING MY CAR IN DRIVE AND WHILE WAITING AT RED LIGHTS. I'VE ALMOST BEEN IN SEVERAL ACCIDENTS BECAUSE OF THIS ISSUE. IT HAS BEEN HAPPENING SINCE I PURCHASED THE VEHICLE NEW. THE DEALER WAS UNABLE TO DUPLICATE THE PROBLEM SO THEY DECIDED THE CAR WAS FINE.
ON 4 SEPARATE OCCASIONS, THE BRAKES FAILED TO STOP THE CAR. THE LAST 2 TIMES, THE CAR NOT ONLY DIDN'T STOP BUT IT ACCELERATED. I COULD HAVE BEEN INVOLVED IN A COUPLE OF VERY SERIOUS ACCIDENTS. EACH TIME, I WAS DRIVING ON CITY STREETS ON DRY PAVEMENT. THE LAST OCCURRENCE WAS ON AUG 14, 2017, AND I TRIED TO STOP THE CAR BY USING THE GEAR SHIFT, BUT THE CAR DIDN'T STOP RIGHT AWAY. THE DEALERSHIP IS CURRENTLY WORKING WITH MAZDA TECH SUPPORT, BUT THEY CAN'T FIND A CAUSE FOR THIS. THEY WANT TO INSTALL A FLIGHT RECORDER, AND FOR ME TO TAKE THE CAR BACK SO I CAN DRIVE IT UNTIL THIS HAPPENS AGAIN. I TOLD THEM NO BECAUSE OF THE SERIOUSNESS OF THE PROBLEM, AND THE DEALERSHIP IS TESTING IT NOW. THIS PROBLEM BEGAN IN AUGUST 2015, AND I'VE ALREADY SPENT OVER $1000 ON REPAIRS RELATED TO IT.
I LOST POWER TO MY 2010 MAZDA CX7 WHILE GOING 60 MP DOWNHILL IN A MOUNTAIN PASS. MY CAR WENT FROM 60 MP TO 40 MP IN ABOUT 30 SECONDS. I IMMEDIATELY PULLED OVER AS BLACK SMOKE POURED OUT OF MY TAIL PIPE AND HAD THE CAR TOWED. MY MECHANIC SAID THE TURBO WAS BLOWN, WHICH CAUSE THE CAR'S OIL TO COMPLETELY BURN UP, CAUSING DAMAGE TO THE TIMING CHAIN AND ENGINE. ALL OF THE OIL WAS GONE IN A MATTER OF A FEW MILES. THE CAR HAD BEEN UP TO DATE ON ALL MAINTENANCE. A NEW TURBO AND ENGINE WAS NEEDED ON A CAR THAT HAD 74,000 MILES ON IT.
LOSS OF POWER WHEN TRYING TO ACCELERATE. PUFF OF WHITE SMOKE ALONG WITH A CLACKING NOISE. *TR
TL*THE CONTACT OWNS A 2010 MAZDA CX-7. WHILE DRIVING AT 30 MPH, THE CONTACT EXPERIENCED DIFFICULTY READING THE GAUGES ON THE INSTRUMENT PANEL IN THE BRIGHT SUNLIGHT. THE CONTACT ALSO STATED THAT THE GAUGES WERE DIFFICULT TO SEE AT NIGHT BECAUSE THEY WERE ILLUMINATED WITH A WHITE LIGHTING. FURTHERMORE, THE CONTACT STATED THAT THE SPACE BETWEEN THE BRAKE PEDAL AND ACCELERATOR PEDAL WERE TOO CLOSE MAKING IT HARD TO DEPRESS THE CORRECT PEDAL WHILE DRIVING. THE CURRENT MILEAGE WAS APPROXIMATELY 700. THE FAILURE MILEAGE WAS 414.
