I bought me car in august 2016 and after 1 month I had to take it to shop to diagnose starting problems and transmission shift problem. Starter was fried replaced it. Then transmission would register each gear but would not move forward or backwards. Had to replace front passenger side CV shaft/axel. Now car temp won't read and it over heated. I immediately parked it left it there went back 2 weeks later to tow it home. Wouldn't start still have to fix temp gauge but i did fix a cracked in the radiator filled with radiator coolant and replacedar battery still won't start. Also found out my cooling fans the 2 behind the radiator are working and 3 of my motor mounts are corroded. Radio keeps switching from fm to CD. It won't shift correctly from 2 to 3 I have to manual shift it and when I start car it squeals for about 10 minutes til I manually up shift while revving engine the downshifting when it hits 5 rpms.
battery light came on. drove it 15 mils to work before it stared shutting down transmission was kicking as I came to a stop and gauges on dash stoped working .
