So this is the sequence of events as to the best of my memory. Everything was working fine, brakes felt normal on the way to the ice store to pick up dry ice for the weekend camping trip. I was loaded up with all gear and my two boys in the back seat and since this was the first trip with the new car, I was curious if I would get any reaction from the AHC (I have not checked pressures yet since I bought the car in December).
Side Note: I do remember that the brake fluid level was above max after I took it to service @ Lexus dealership, so you might be on to something about the brake fluid corroding the wire connection.
As I pulled into the parking lot, it seemed like I heard a crunching sound coming from the drivetrain, but thinking back it mayI have been the crumbling cement under the tires. I pull in, reverse to position the car to pull into a parking spot and warning lights appear and go crazy complete with the high pitch warning tone. I immediately think its the transmission, transfer case or the differentials since I heard a crunching noise before. There are no fluids leaking, and at this time I learn that there is no transmission dipstick to check fluids (hahaha). So I then try to shift transfer case into N and L, still trying to diagnose what I thought was a drivetrain issue. I put the gear back to H but the transmission was having some trouble going back into P. I got it there with more force and a little grinding (oops!). After walking around the car again scratching my head in confusion, I got back in and started reversing a little, then driving forward, reversing thenout of nowhere with no indication, the brake pedal goes to the floor. By pressing hard at the end of the pedal stroke I could feel a very small amount of brakes, but not even enough to stop the car from rolling fwd when in D. I used the hand brake to stop and started searching the internet and I came to realize that "I was experiencing what I have seen every day at the top of 100-series forum on ih8mud!"
Anyway, I will definitely ask to keep all the parts the dealer removes and post pics when I see them, or report back any news.
