To take it a little further...
I also have an 07 4.6 V8 but I have just over 30,000 miles.
I've had similar problems with mine -
1. The traction control light under the radio went on a few times - one time - while I was braking - the brakes were in anti-lock mode but I was just VERY LIGHTLY braking. It was weird. I was just slowing down - not pressing the pedal hard at all - but I could feel the pulsating as if I where mashing the pedal. Pulled over and restarted the truck - all was fine.
2. The Left Rear turn signal bulb was bad (that's what the computer told me) - like 4 times. But when I restarted the truck, it went away and all was fine.
3. The Tire Pressure sensor told me several times the tires were low on air - but they weren't.
In all cases, the computer was flaky and a simple restart of the engine solved the problems. I've taken it to the dealer and the problems weren't present (of course).
It's been 4 months with no problems at all... but again, remember - there were never really any problems to begin with - the computer just thought so.
