Hey guys , I'm new to all of this ,,,, this meaning forums
Just purchased a 2010 g37s. Has anybody added anything to increase hp ??

does anybody out there have any problems with the G37S battery not charging. Specifically, after a couple of days of not starting the car the battery is dead? please let me know. I have had my car in the dealership 5 times for the same problem and dealership can't find the problem. Would appreciate any feedback.
