Bought the coupe, runs good , however when starting up all the light in the dash turn on, and when I put it in gear, it shifts very hard , when I go it appears to not shift by itself, I took it to a mechanic run diagnostics, and it resets, I turn off switch numerous of times, and it's back to normal.. does anyone know what causes that? ? Spoiler goes up and down as well?? If someone could give me an idea that would be great. . BTW mechanic, couldn't tell me cause he would have to have it there for a dew days .. Salomon
