So one day i pushed the 300 to 160+ and when i showed down j realized my windows, dash lights, stereo, and ac/heater didn’t work it was no power at all car was driving great. Then the blind spot failed and showed in dash. But after driving the power returns and stays on then goes off randomly when speeding up rapidly and stays off till slowed down or sometimes it stays off. When stopped and going slow. Not sure what the issue is but any ideas? I’ve checked and googled so much and i haven’t found a fix. But as of today the inside of the car has power but shuts off randomly and comes on randomly. Please let me know your input.
