The other day when I was driving home from Ohio, I was at about 703 miles after 10 hrs of driving and all of my electronics shut off. The dash went out and so did the radio. It didn't seem like I lost any engine power, but the navi, radio, and dash all went out. It came back on almost instantaneously, but then went out again and then back on.

I took off the battery terminals, they looked clean, but I and cleaned them with a wire brush anyways. I checked the ground and it looked fine. There wasn't any corrosion in the wire that I could see either.

Anybody have any ideas as to what the issue could be? The car is a 08 TL-S with a little over 72000 miles on it.

 

Get the battery checked and then have a charging test done. Prol would be good to bring it to a stealership or good shop that can do that test.
