general problems of the 2006 Lexus GS

I have a Lexus Gs300 2006. The lights have been shutting off, turning off intermittently. It is usually the right side but also happens on the left side. You can fix the problem by turning the on off switch. However it will continue to shut off randomly. This is a safety hazard and needs to be addressed. It has been happening for over a year and Lexus dealership says to replace just the bulb. The bulb is fine, something else is wrong. Others have complained as well.

Headlamp (afs) does not work properly. Right headlamp supposed to be auto leveling does not work properly and faces to the ground. Asked the dealership to fix it while it was under warranty and was told they did. (afs) has never worked and right headlamp falls and faces to the ground and was told by another dealership how to fix it my self. Headlamps also would turn off at night and not work and was on a trip and had to wait until they wanted to turn back on again. The headlamp still today does not face at normal degree and cannot see on the right side very well. Total cost to replace the entire head lamp is over $1,200 and was told that warranty do not cover this ever since I have complained. There is also "supposed" to be a safe guard warning the driver that the headlamps are not functioning correctly and it does not work either. No alarms go off, no lights either. Searched the internet and have found the same thing as well. Head lamp flickers and headlamp facing the ground. Steering wheel also is never level and I have had it "corrected" but im told that it is "just the road" it is never straight. Brakes have to be pushed to the floor the pump is very loud and also am told its normal. Suspension has a banging sound as well since I have had the vehicle too.
