I was driving and all the electronics turned off and began to lose power. All system returned to normal in 10 or seconds. I called the dealer before driving an hour away. The dealer asked if keys were heavy and I only drive with the key and alarm button and battery isn't even 2 years old yet. 05 TL no Navi

 

Did you check your battery connections?

 

Hm....
Do you have any additional appliances/electrical installed on your car?
How many mileage do you have on your vehicle?
When you say that all your electronics turned off while operating your vehicle, explain?(i.e):
Headlights diminishing, radio cut off, any stuttering in the display, dashboard lights flickering, etc..?
Did the car power off as well?
Did any warning came up, for example, air-bag, tire pressure, etc...?

Hopefully with these questions answered, someone could assist you.
Happy holidays!

 

Sounds like a low voltage situation.

Check the battery connections like suggested above and check the battery.
