NHTSA Complaint #11420064 — 2013 MAZDA MAZDA3

There is a loud winding sound sound coming from the transmission and sound of metal (broken teeth) as well. We took it to a Mazda dealer and they quickly identified the issue as a failing transmission. As a result I was able to find that a service bulletin aligned with this issue (TSB No. 0500414) and confirmed this with the dealer. This service bulletin indicates a manufacturing issue but only applied a warranty of 6 years or 60,000 miles. Yes, our car is over the 6 yrs and only 800 miles over the 60,000 miles, however, my concern is that this is a known issue that clearly becomes a safety issue. We got a price from the dealer of $4,500 for a new transmission so I took it to a transmission shop for a 2nd opinion. They confirmed the failing transmission and indicated the car should not be driven for safety reasons. They said the transmission is in bad shape and when it fails the car will just stop creating a very unsafe condition. They are able to find a used transmission and install it for an estimate of $2,700 but I believe this should be covered by Mazda due to the safety concerns. I have no choice to proceed with this replacement but hope that you can help to get Mazda's attention and have them stand behind this and cover this cost.
