Bought a 08 LC200 with the 4,7L V8 a few weeks back. Today while starting up the car I noticed that the front lowered slightly. I drove for a few miles and then stopped to check the AHC. It goes into "HI" without a problem, when putting it back in "N" it seems a little low and the front is marginally lower that the back. It won't go into "LO" at all - just flashes the "LO" indicator. Any ideas??
