NHTSA complaint #11683090

Owner complaint summary

Transmission failure, currently reproducible but car is at dealer to be evaluated/repaired. I was safe as I was still in my driveway, however if I was in traffic I would be at risk of an accident, by the time you realize you are not moving you have already let off the brake and could be rolling, fear is that if it happens at a traffic light other drivers woudl assume I am going to accelerate but I'm not. First time this happened dealer reproduced issue, contacted Mazda, and a replacement valve body was installed. Now that it has happened again within the first 33K miles it creates a trust issue. There were no warning sign either time the transmission failed. I also do not drive aggressively, wife says I drive like a grandpa. about 10-15 seconds after failure the alarms and warning lights go off.
