So, I leased the silver 2015 GT w/Tech pkg at the end of January last year. I made the mistake of not test driving the one I ended up getting, because I had test driven four others; I figured they were all the same, so the first time I drove it was on the way home. I had throttle and transmission problems with it the whole time I had it. The dealership where I got the car claims to have replaced the transmission in April, but I continued to have problems with throttle response and the transmission downshifting, and two dealerships couldn't figure the problem out. The car was also sideswiped in a parking lot in May. The body shop never could get the doors to hang correctly, so they always rattled and rubbed along the weather stripping when going over bumps. The issue with that same dealership claiming to have replaced the bluetooth module based on this TSB, but didn't actually do anything, got me to the point where I just needed to dump the car and get something else.
When I brought it to what we'll call dealership #3, which is 15 miles (but a 45-minute drive) away from my house, to FINALLY have the Bluetooth module TSB repair performed, I asked the service advisor if I could speak with someone about running the numbers to see if trading it in was even remotely an option. I really didn't think it would be possible, but it turned out that I was only a couple of hundred dollars upside down, so I was able to trade for a 2016 GT (w/o Tech pkg this time.) The payment is $12 higher, but the new MazdaConnect system is worth the loss of the tech package options.
