    Any of you guys seen this before? My battery light flickers faintly and there are no error codes. Voltage seems steady and the battery is a 6 month old AGM. No loose battery terminals or grounds.

    I tried taking a video but it wont load from an iphone.

    Any luck on the issue? My battery light flickers intermittently and im getting intermittent engine misfire. My battery voltage is good (a little over 12V) and while the engine is on and accessories on (lights, radio,blower) voltage around 14.1V so it doesn't seem like its the battery or alternator.

    @Tundra John, did you get the battery light flicker figured out. Mine is flickering after a tint job.

    This exact thing happened to me today. Just got my front windows and windshield retinted after having to remove it for inspected and the drive back home I noticed the battery icon flickering on the dash. Googled what a flickering battery light might mean and results came up as a possible alternator failure. Anyone else have anything like this happen and figured it out?

    @that0ne6uy1618 mine only did it for a day then went away and has not come back, its been 3 days. I guess it was some water in the dash, hope it stays away.
