You know the one that says the charging system needs to be checked out. Well I took it to my local Hyundai and the tech got the codes BM25xxx. I don't recall the exact codes, but he basically said it was the junction box for the rear left and right turn signals. He said that the aftermarket HID system is drawing too much power and is tripping the junction box. He mentioned something about CANBUS system also. I bought the xenonsupply ballast which had the CANBUS feature built in. I will take it off for now and see if the light comes back. Will suck if it doesn't cause the HID seems to be great. Only weird thing is the light came on after I dropped my kids off to school. I had the lights set to off so there is no way the headlights (no DRLs on) could have drawn power, but the codes were there and the notes showed the junction for the rear turn signals. Any other thoughts? Car drives fine and charges fine just the light.
