On [XXX], I was the operator of a 2019 Mazda CX-5 in Los Angeles, California. I parked the vehicle on an incline on or around [XXX] in Los Angeles, California, and then exited the vehicle. The vehicle remained stationary for some time, until it suddenly began rolling backwards at a speed that pushed me to the ground while I was getting my things from the passenger side door, causing me serious injuries.

TRAFFIC WAS HEAVY ON THE PARKWAY THAT DAY SO THERE WAS A LOT OF STOPPING AND GOING. APPLYING THE BRAKES, THE CAR STARTED TO SLOW DOWN BUT SUDDENLY THERE WAS A JERK AND THE CAR ACCELERATE WHILE THE BRAKES WERE STILL BEING APPLIED. THERE WAS A FRONTAL COLLISION WHICH INDICATES THAT THE SMART BRAKES SYSTEM WAS ALSO NOT WORKING. THE WARNING 'BRAKE SYSTEM MALFUNCTION' APPEARED ON MY DASHBOARD AFTER THE ACCIDENT. MY INSURANCE COMPANY SENT A WRITTEN REQUEST FOR THE EDR TEST AND HAVE AGREED TO PAY THE FEE WITH THE EXPECTATION OF BEING PROVIDED WITH A QUOTE OF THE COST AND THE END RESULTS. MAZDA HAS NOT APPROVED THE REQUEST AND IT HAS BEEN OVER 3 WEEKS. ASKED TO SPEAK TO A SUPERVISOR AND DID NOT GET A RESPONSE.

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 2019 Mazda Cx-50 verdict →
