While driving at 60 MPH on the highway, the vehicle struck a boat that broke free from a towing vehicle and ended up in the middle of the lane. The seat belts were being used at the time of accident, but none of the six air bags deployed. The police did arrive on the scene and no one was injured. *scc

Reported at 7,000 miles Crash

I special ordered a 2003 lexus is 300 in 2002 in which waited 2 months for its arrival. There has been several recalls with components on my car but lexus selected just a few to send letters to. Initially, the dashboard was manufacture with defective material and lexus corporation refused to take care of it. I am still working on this issue then there is the sensor2 bank1 which my trac off blinking and check engine light stays on.

Reported at 48,600 miles, March 2013 Crash

High wind noise and flapping noise from the driver door; it's very annoying and unconvertible driving on the highway because of the noises produced by this problem. Lexus claims their cars as luxury cars, but also claims that a wind noise and a flapping noise are normal for $34k luxury cars. I took the car in and they even did not want to try to fix the problem.

Reported at 12 miles, October 2003

The dashboard is in very poor condition with a sticky and melting appearance. I complained to lexus of toyota and was told that the warranty would not cover to replace or fix the problem. Considering that I did not have money to replace this with my own funds, I did not pursue it.
