My car sat garaged during the winter and the battery had died, so we jump started it, not a trickle charge (big mistake). Now all sorts of messages come up and the signals don't work, the trunk won't open, gas gauge says I have a roll bar issue,top won;t go down and a few other issue. Seems to be all electrical issues. The car drives. I am being told I need a new SAM module. Does this sound right, and what would you estimate this repair to be? I have 182,000 miles on it. Excellent condition otherwise. Thank you.
