On several occasions, most of which happened while in motion, my vehicle has stalled out of the blue with no warning. It seems to mostly happen when I’m slowing down or when I’m making a right hand turn and try to accelerate, suddenly there’s no power to the engine. I have to put the vehicle into park and restart it. Twice while slowing down for a red light. Twice immediately after making a right handed turn, and once, when entering roundabout, after yielding. This is happened at least five times. The most recent incident occurring in August 2023.

ON MY 2010 MAZDA 5 SPORT, THE INSTRUMENT PANEL LIGHTS UP AUTOMATICALLY WHEN IT IS DARK OR DIM OUTSIDE. ON PREVIOUS YEARS OF THIS VEHICLE, AND ON ALL OTHER VEHICLES I HAVE EVER DRIVEN, THE INSTRUMENT PANEL LIGHTS UP ONLY WHEN THE HEADLIGHTS ARE SWITCHED ON. THIS IS WHAT PREVENTS PEOPLE FROM DRIVING WITH THEIR HEADLIGHTS OFF. THE SERVICE DEPARTMENT AND MAZDA CUSTOMER ASSISTANCE BOTH CONFIRMED THAT THE CONTROLS ARE WORKING THE WAY THE CAR WAS DESIGNED. THE RESULT OF THIS DESIGN CHANGE IS THAT BOTH MYSELF AND MY WIFE HAVE DRIVEN THE CAR IN THE DARK WITH THE HEADLIGHTS OFF. I HAVE TOLD MAZDA CUSTOMER ASSISTANCE THAT THIS DESIGN FLAW WILL CERTAINLY RESULT IN ACCIDENTS FROM PEOPLE DRIVING WITH THE HEADLIGHTS OFF, BUT THEY SAID THERE IS NOTHING THEY CAN DO. I HOPE THEY WILL NOT WAIT FOR SOMEONE TO HAVE A SERIOUS ACCIDENT BEFORE THEY TAKE NOTICE. *TR

I WAS DRIVING HOME AFTER DROPPING MY THREE CHILDREN OFF AT SCHOOL. THE ROAD THAT I LIVE ON IS WOODLAKE PKWY AND THE SPEED LIMIT IS FOURTY-FIVE MPH. A LADY IN A CAR PULLED OUT IN FRONT OF ME FROM A SUBDIVISION ON MY RIGHT, SHE WAS HEADED IN MY OPPOSITE DIRECTION. I HIT HER AS I ATTEMPTED TO SWERVE AND MISS HER ONLY PROJECTING ME FURTHER AND FASTER TO MY LEFT WHERE THERE WERE TWO SETS OF TREES AND BUSHES. AFTER THE INITIAL COLLISION I THEN FOUGHT MY WAY THROUGH TREES REALIZING I HAD NO BRAKES I SLAMMED DOWN THE BRAKES AND LANDED ON SOME TREE STUBS 150 FT AWAY FROM THE CRASH SITE. MY AIRBAGS NEVER DEPLOYED. *TR
