Transmission Failure problems of the 2016 Mazda MX5

While driving on a public 2-lane road and upshifting into 3rd gear at about 6,500 rpm my transmission failed. I immediately slowed from about 65 mph and coasted to a stop. I was lucky that there was a just adequate shoulder, and I was able to avoid being rear-ended by faster traffic. I pulled as far to the right as I could, still withing 4 feet of the pavement. I determined that I could still drive in 1st gear and, driving only on the shoulder, drove the car to a wider, safer spot. A friend came by later with his truck and trailer to take my car to my home. I thereupon had it towed to a Mazda dealer the next day. The dealer diagnosed a manual transmission failure, 3rd gear specifically, and told me I was lucky the gearbox didn't sieze and cause a lack of control. They replaced the entire transmission at no cost to me.

Transmission is made of weak grade materials and running at high temps causing the transmission to fail randomly while driving. I am on my second transmission and Mazda fails to help or address the concern. The problem has been proven by many shops at this point and most importantly by a Mazda engineer on a youtube video. This Mazda engineer specifically states that weak tolerances are causing manual transmissions to shear teeth under load. Both times my transmissions parts exploded I was at speed. The first time was on a city street, the second time was on a very busy highway during rush hour. The first time, no gears were usable and I had to be towed home after coasting my car to a stop in neutral. The second time I could only use 4th gear and had to limp home.
