My car was squeaking and lurching around 3/4 gear. I took it in to the Mazda dealership (Northtowne Mazda in Kansas City) and they told me it was a "well-known issue" with this year and make of a Mazda. There is a problem with the torque converter lock-up clutch which sheds iron particles into the transmission fluid. The torque converter needs to be replaced. After further research, it appears that Mazda has a well-documented manufacturing defect that is outlined in Mazda TSB 05-005/23. My car has a 60,000 mile/5 year warranty on it. It currently only has 48,600 miles on it (well under the warranty limit). I called the Mazda Corporation Customer Care and they opened a ticket but I was told …

There is a module that should connect to the hatch door to open. That module in no longer available. Without the hatch door opening, in case of side impact and being pushed into something else, there is no way to get out of the car. This poses a serious safety hazard. I have contacted the Mazda dealership and I am told that the part is "retired" and there is no replacement part at this time.
