Unknown Or Other problem #1

When driving with the air condition on, a sulfur like odor entered through the a/c vent. The condition caused headaches and nausea. The driver rolled down the windows and turned the a/c off to allow the fresh air to removed odor. The vehicle was taken to the dealer and they were unable to locate the problem. Please provide any further information and complete this questionnaire.

Unknown Or Other problem #2

I have owned 2 Gx470's and both have had a "knocking" when you stop the vehicle. It feels as though someone has tapped me from behind my vehicle with their vehicle. Lexus customer service, dealer and technician claim this is normal for an SUV. I have owned a mercedes ml 430 and there was never a thump from the rear.
