All Electrical Stoped Working

[seohenning]

I recently had a big problem with my 06 IS250 AWD. I went to get into the car and the doors wouldn’t open, so I got in manually with the "key" and tried to start the car to no avail. The wheel wouldn't move and the break wouldn't depress and there appeared to be no power, and thus no way to start the car.

My initial thought was that the wheel lock had been triggered and the battery was dead, so I tried jumping it (correctly) however I could not depress the break and thus the push button wouldn't star the car. However, it appeared that no electrical was working and the push button start wasn't responding to the key? My second thought was that the key battery was dead, however that was not the problem as I tried both sets of keys and replaced the batteries. So reluctantly, I had it towed to the dealership where they spent three days searching for a problem.

The result after three days at the dealership (so I have been told) was CORROSION on a ground in one of the wire harnesses located just in front of the firewall on the right hand side of the car. Apparently that was enough to shut the entire car down. I am wondering how a 2 1/2 year old car can build up that much corrosion and how something that small can shut down everything in the car. Also, what else is in store for future years? I am picking it up from the dealership but I want to make sure that something like this can't happen while I am driving.

I figured I would post this in the event any of you are unlucky enough to experience this. Luckily it is an easy fix and there was no major damage done! But regardless it took a lot of hours to track down the problem.
