On the 4th of July my family and I were driving to westchester from manhattan. We had a full tank of gas, recent oil change and new car battery. The car is always maintained and it has never given us any trouble. During our drive we noticed something was wrong. The the car started to feel hot, but we weren't too sure if it's just hot out or if there was something wrong, because the ac was on. We pulled over and turned the car off. We checked the coolant and saw that we had oil. We opened the trunk, felt around to see if it was hot and to see if we smell anything. It seemed fine. As soon as we drove off, not 2 minutes in, when driver said the gas petal felt weird, it dropped from 50 to 30 to 20mph and we heard a light drilling noise. As soon as we stepped out of the car, it was in flames. Our family could have died. Https://www.facebook.com/valhallafd/posts/1548408978544577

Shortly after purchasing vehicle replaced timing, turbo, exaust, ball joints, tie rod ends & much more. Timing was first, then driving and turbo went out. 2 days ago car sitting in driveway, not running, started smoking from under hood, butst into flames and burnt up. Mazda said no recalls, clearly not true according to website. Almost burnt my house also as it was sitting in driveway and couldnt be moved. If we would have been inside the car, I doubt we would of had time to get pulled over & out as thats how quick it burnt!

Took my car to an independent mechanic. Computer registers that there's something wrong with intake but, once removed it works fine. Checked EGR ventilation system works fine. Car still cuts out during acceleration. Idles very high he informed me that there's a problem with my computer electrical systems. I need some information pertaining to Mazda recall.
I got into a Mazda forum where many costumers are having problems with the air conditioning clutch failure (seized) loosing power steering while driving. Turbo failure, causing engine overheating. Timing belt failure. I can not find any recalls about these failures.
Air bags have been replaced after recall in July of 2018 and air bag l8ghts hace come back on in October 2018. Both driver and passenger lights come on while driving and when stationary after starting the car.
