Have the battery and alt tested for free at the local parts store. Tell them what it's doing, and start suspecting a fuel issue. Could be getting the right amount of fuel but not burning it. (plugs, wires, coil) Or could not be getting enough fuel.
Still hard to say, so get the charging/power system checked first. Let me know what you find out as I'm real curious now.
Same happened to a friend and it was the fuel pump.... Same for another friend and it was 2 bad coil packs.
I will do some research on the headlight problem. An awd system should not bind in a turn like a 4wd does on dry pavement,because the awd has a limited slip differential. And any kind of noise coming from the rearend is NOT normal. You should report the dealership employee that told you this to the factory regional representative. It borders on gross negligence.
I think you should check your battery and alternator.If they both check good you may have a battery draw,something draining the battery over night.Check your doors make sure they are closing like they should.
If fuel filter hasn't been done lately I would start there & if you can, have fuel pressure tested while your at it. You may have tired fuel pump but pressure test will confirm. If you recently filled up somewhere different last time you got gas, I'd also try some "Heet" or similar just incase you got a tank full with some water in it.
Last night I checked the battery and it was still good. I disconnected and then reconn ected both terminals and that brought the power back. When I turned the key the power went out again. I repeated the procedure but did not turn the key. Instead, I took off the knee bolster and tried to wiggle the wires under the dash to see if I could find the source since it seems to be related to the ignition. Nothing cut the power so I started it up and it worked fine except for the check engine light which was flashing that says I have a misfire condition. I drove the car 25 miles to work this morning and will be taking it to the dealer for a better inspection.
