NHTSA Complaint #10477056 — 2004 MAZDA MAZDA6

I PURCHASED MY CAR USED IN OCTOBER 2011. MY CAR FREQUENTLY STALLS ON THE HIGHWAY AND I HAVE TO EITHER PULL OFF TO THE SIDE OF THE HIGHWAY TO RESTART IT OR PUT IT IN NEUTRAL AND RESTART IT WHILE COASTING ON THE HIGHWAY. THIS ALSO HAPPENS AT SLOW SPEEDS BUT IS CLEARLY A SAFETY ISSUE AT HIGHWAY SPEEDS. MAZDA PUT OUT A SERVICE BULLETIN ON THE THROTTLE BODY IN 2006. I HAVE BEEN TRYING TO PURCHASE A REPLACEMENT THROTTLE BODY SINCE JULY 2012 AND HAVE FOUND IT IMPOSSIBLE TO FIND THE PART AND HAVE BEEN TOLD THE PART IS ON A NATIONAL BACK ORDER. OBVIOUSLY MAZDA KNOWS THERE IS A PROBLEM WITH THE PART OR THEY WOULDN'T HAVE PUT A SERVICE BULLETIN OUT. I FEEL MAZDA IS PUTTING LIVES AT RISK BY NOT MAKING THE REPLACEMENT PART AVAILABLE. *TR
