AS I WAS TURNING INTO A PARKING SPOT TO PARK MY CAR, THE CAR ACCELERATED ON ITS OWN AND RAN INTO A CONCRETE WALL. I HAVE HAD ISSUES WITH THIS CAR'S PROGRAMMING, INCLUDING WHEN I TOOK MY CAR IN TO GET FIXED AFTER THE SAFETY RECALL IN JANUARY '16. AS I REALIZED THE CAR WAS ACCELERATING - AND PUSHING ON THE BRAKE WOULD NOT STOP IT - I LIFTED THE EMERGENCY BRAKE. THE CRASH ULTIMATELY STOPPED THE CAR - NOT THE BRAKE OR EMERGENCY BRAKE, AND THE AIRBAG DEPLOYED. LESS CONCERNED ABOUT THE DAMAGE TO THE OUTSIDE OF THE CAR, AND MORE CONCERNED THAT I HAD ZERO CONTROL OVER THE CAR AND ANY ABILITY TO STOP IT.

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 full 2014 Mazda Mazda3 Hatchback verdict →
