I dont want to lull you into a false sense of security, but if all 
those came on at once, I'd suspect some form of dash/electrical 
malfunction. i doubt they all died at once, and I dont see the obvious 

Start out with simple things.  Measure the water temp (infrared or - 
heavens - a thermometer) and see if tis in fact high.

I doubt brakes, Oxygen sensor (not Apple's operating system, right?) 
and thermostat all failed at the same exact instant.

Ground fault.  Voltage spike? Voltage regulator?
