It was the alternator... Got it at O'reilly's. It came with a lifetime warranty so they replaced it for free.

I would love to only buy Toyota parts but sometimes the budget doesn't allow. If I don't buy Toyota, I always at least try make sure the part is a decent brand and comes with a lifetime warranty.

For the umpteenth time, Toyota does the simultaneous CHARGE / BRAKE lights ON PURPOSE, to attract your attention so you know something important is wrong; usually MC fluid level or bad alt.
