I WAS CALMLY DRIVING SLOWER THAN 35 MPH ON A CITY STREET WHEN THE CAR SUDDENLY SLOWED DOWN AND STOPPED RESPONDING TO THE ACCELERATOR PEDAL. WHEN I TRIED TO STEP ON THE GAS I HEARD A BIG EXPLOSION-LIKE SOUND. THEN ALL OF A SUDDEN THE CAR ACCELERATED TO WHAT SEEMS LIKE OVER 100 MPH AND THE BREAKS DID NOT WORK DESPITE ME PRESSING THE BREAKS SEVERAL TIMES. I SHOT INTO 3 CARS AHEAD OF ME THAT WERE AT THE RED LIGHT. THE OTHER CARS RECEIVED SUBSTANTIAL DAMAGE; I SAW THAT OTHERS WERE INJURED. MY CAR WAS COMPLETELY DAMAGED/CRUSHED IN THE FRONT AND A FIRE HAD BROKEN OUT. THE AIRBAGS HAD DEPLOYED AND I WAS PRETTY MUCH PINNED TO THE SEAT. I HAD BOUGHT THE CAR FROM THE DEALER BRAND NEW AND HAD IT REGULARLY SERVICED AND MAINTAINED. I WAS THE ONLY DRIVER AND IT HAD ONLY 30000 MILES OVER 3 YRS.

How to use these: a complaint is one owner’s report, filed voluntarily and published unverified. Patterns matter more than any single story. If several owners describe the same failure at similar mileage, put that system at the top of your
pre-purchase inspection list. Back to the
