FILING THIS COMPLAINT SINCE THERE IS A RECALL ISSUED FOR MY SAME MODEL YEAR IN CANADA (SPECIAL PROGRAM 76) FOR THIS EXACT ISSUE DUE TO SNOW AND SALT.

Air bags

“For a year I have responded to every notice for a recall repair (7 total) Mazda has not repaired my vehicle or scheduled its repair. My recall ID is 016742248 and my Campaign Number is 100409. My car has a DO NOT DRIVE status and Mazda tells me I MUST drive the car 2 hours to get it repaired each way. And they refuse to transport y vehicle even thought I have told them in phone conversations about my cars do not drive status. The latest attempt for filing for a repay was 7-21-25 at 9:40am central time.”
Electrical system
35 reports1 fire
“ELECTRIC-ASSIST POWER STEERING, RANDOMLY IN THE PARKING LOT THE WHEEL WILL TURN ALL BY ITSELF, ONE WAY TURNS EASIER THAN THE OTHER, SOMETIMES YOU HAVE NO POWER STEERING AND OTHER TIMES YOUR STEERING WHEEL TURNS LIKE BUTTER, I LIVE IN THE MOUNTAINS WITH A VERY WINDY AND DANGEROUS ROADS, I'VE TAKEN IT TO SEVERAL MECHANICS FINALLY ONE MECHANIC JUST UNPLUG THE WIRING HARNESS SO THERE IS NO POWER STEERING. IT IS VERY SCARY TO DRIVE ESPECIALLY WITH A NEWBORN BABY. THERE ARE A LOT OF CARS ON THE ROAD WITH THIS ISSUE I KNOW 10 DIFFERENT PEOPLE THAT HAVE SOME SORT OF POWER STEERING ISSUE. THIS IS VERY DANGEROUS AND I'M SURPRISED THERE IS NOT A RECALL YET ON IT. I'VE HAD TWO FRIENDS THAT ARE CLOSE TO ME THAT HAVE THIS ISSUE AS WELL, ONE FRIEND WRECKED HIS CAR THE OTHER FRIEND SOLD IT I BELIEVE TO PICK-N-PULL SO IT WOULD NOT HURT ANYONE, PLEASE HELP AND MAYBE HELP SAVE A FEW LIVES, THANK YOU FOR YOUR TIME AND I LOOK FORWARD TO SPEAKING WITH YOU”

“The contact owns a 2004 Mazda RX-8. The contact stated that while driving at an undisclosed speed, the vehicle inadvertently lost motive power. The contact was able to pull to the shoulder of the roadway, where the vehicle failed to restart. The check engine warning light was illuminated. The vehicle was towed to the dealer, who diagnosed a failure with the engine. The dealer determined that the engine had no compression. The vehicle was repaired, but the failure reoccurred. The manufacturer was notified of the failure but provided no assistance. The failure mileage was 60,000.”
