So the 12v battery issues continue to plague these cars. I jumped in it tonight to show it off to a friend (Great timing) and had this error on my dash. I was in the process of buckling up, and by the time I did, the error cleared. Started normal, drove normal, etc. Hung at his place a bit and then drove home. No errors, no problems. I had about 90 miles of range left. I'll probably call service in the AM to see if they see anything. That and the brakes are squealing like a mother! Also doesn't show off well to friends! But otherwise, huge grins! Me and the rest of the family and friends! This is the best go-kart I've ever owned! Just hoping the battery and brakes aren't a bad sign of things to come!
