In August of 2005 I purchased a Mazda 6 (automatic transmission). After 2 - 3 weeks of ownership my Mazda died on me one day while driving on the highway. I immediately took it to the dealership yet no problem was identified. 4 - 5 months later my car stalled while sitting at a light. A couple of months after that, my Mazda stalled again. A couple of days ago while backing out of the driveway my car just turned off. It's so annoying because I always take it to the dealership immediately after the stalling occurs and they can never identify a problem; they try to recreate the conditions and put miles on my car but it doesn't stall for them. When it stalls there is no warning (I. E no lights, engine noise,etc). It turns right back on immediately; I notice the lights and the fact that my engine is no longer on. I simply put the car in park and turn the ignition and the car runs fine. This stalling occurs every 5 - 7 months. I've complained and complained to every Mazda dealership I've been to and have sent multiple emails and made multiple phone calls to the corporate office about this issue. Because the problem can't be identified the Mazda technicians can offer no remedy.
