I'm at GTS motor on long island, Nassau county and they say I need a new computer . For some reason I doubt it, but what do I know...they say that's why I'm getting trans failsafe msg, 4x4 msg, dsc. But how do u explain the radio cutting out or nav screen cutting out. Trans stuck in 3rd gear. The computer also said the voltage is 14.21.

car now had 59 plus k miles.
