I bought my 2008 Mazda 6 with 36,000 miles on it.
Right away, I had A/C issues.
With 90,000 miles on it, I had to have the transmission rebuilt and change out the valve body.
As I now understand it (reading consumer reviews on the issues of this car), the valve bodies are made overseas and built with a poor grade metal so these cars have transmission issues.
I finally sold the car 1 month ago having rebuilt the transmission and fixed the A/C 3 times.
I had only heard good things about Mazda's, but I won't buy another one.
Transfer manufacturing of valve bodies to another location that would build with better grade metal.
