I've been driving my son's FJ Cruiser for a few months while he is working out of town, so I'm not very familiar with these vehicles. I have an FJ 40 and an FJ 60. Today I was driving it, and the radio started acting squirrely. Then I noticed nearly all of the warning lights came on. The one with the icon of the battery, as well as the one that said the emergency brake was on, which it wasn't, and some other yellow lights. The amperage meter was 3/8 of the way toward negative. When I read the owners' manual it said if the battery light or the brake light come on, stop the vehicle and call the dealer immediately. Well I stopped to try and figure things out. I was going to drive the 4 blocks left to go home, but the car is now stone cold dead. It absolutely won't turn over. Is this simply a battery problem, or something more? The battery is 16 months old, and it's a 3 year old battery.
