Car loses complete power

[Jucharles]

When I power my car on it sometimes complete shuts off and all power cuts off. I thought it was the battery so I had that changed . Then I thought it was the recent recall and that was also fixed but it continues to lose complete power at random times . Is anybody with a 2016 Hyundai Genesis dealing with this same issue ?

Yes, I had a simular issue. When I would push the start/stop button to shut it off it would do the same thing, complete power failure, no lights, nothing. After a few minutes everything wouild come back. Well one time it didn't come back on so I took some voltage readings with my digital muliter meter and the voltages read around 3 volts under the hood, so I did a direct reading on the battery terminal and it was over 12 volts. I took the neg and positive terminals off and cleaned them up really good ( a little corrosion) and the problem was solved. The battery terminals on these cars are not the best, so you have to make sure you have a good connection. I believe that my problem was there since new, but had progressively gotten worse.
Good luck,
Bill

I had this issue as well. Another member posted on here that the terminals on american batteries are a little smaller in diameter then the european batteries. this causes the plastic positive terminal box on the battery to actually move even when the positive terminal is tight. You will find you can take some cardboard and fold it up and wedge it under the lower left corner of the battery box. Just lift it up a little and wedge the cardboard under it. Voila! Problem fixed. You may have to adjust every once in a while. It used to happen to me 2-3 times a week. Now it happens maybe once a month. Hope that helps!
