If your concerned about safety and have loved ones, you probably smart to buy anything but a Lexus. My wife was in a one month old RX300 that was hit broadside by a drunk. Her vehicle was pushed laterally approximately 40 feet into a telephone pole, overturned and demolished. Since we had owned Lexus vehicles in the past, after a visit to the hospital I contacted Lexus as I was concerned about the fact that the driver side airbag failed to deploy. After a series of calls they finally sent an 'engineer' to examine the wrecked RX300 in the junk yard. He took a few photos. As an engineer, I wrote Lexus asking for the specifications for the airbag deployment. In spite of several letters they never sent me the data requested, however, several months later Lexus told me the airbag failed to deploy due to an insufficient impact! When I asked them why the vehicle flipped over due to an insufficient impact they refused to comment.

for information and pictures. So far, several persons have contacted me concerning similar apparent airbag failures. If you value the life of your loved ones at the very least get your Lexus checked.
