Hey guys I noticed the other day that when I got on my car a bit to redline the E brake light comes on every time now! I just replaced my old optima red top which was beyond shot, and I don't recall it doing it before so I'm not sure if it is related. The same day i replaced the battery for some odd reason the radio stations wouldn't come in, and had a high pitch wining noise that increased with engine rpms. It hasn't done that since though.... I've had the service tcs/abs problem for awhile now since i replaced the front right hub bearing and sensor shortly after, hoped it was just the bad battery but that was confirmed to not be the source of problem. Anyways here's a quick video of me punching it and the light popping on, I've never heard of this issue before! Sorry for lack of traction and a little limiter.
