NHTSA Complaint #11504977 — 2010 MAZDA MAZDA3

The Transmission Control Module (TCM) has gone out on my car, causing it to shift to 2nd gear while doing 75mph with cars around me, and would no longer shift out of 2nd gear, or into reverse. It was an extremely dangerous situation that made me come very close to wrecking into a car, as well as the many cars behind me that had to emergency brake due to my rapid deceleration, especially without and brake lights coming on because it was engine braking. Doing a simple google search show that this is an extremely well-known problem effecting almost every Mazda 3 that used this TCM in 2010-2011. Any mechanic will tell you it's a known problem, and that it was due to where and how Mazda placed the computer, which causes it to overheat and fail without warning. I'm not sure why there has not been a recall on this issue with how prevalent it has been, and how easily recognized it is by mechanics. It is not a cheap fix, and can cause many other major issues leading up to requiring a full new transmission, if the problem did not already cause the car to wreck!
