Lexus LS430 Transmission problems by year

had replaced multiple driveshafts in the past & that this condition is absolutely not normal. However, he, & I'm now using my own words, must hold the company line, & tell customers what they're being instructed from lexus headquarters. As a police supervisor, I drive for a living. I've never experienced a vehicle "jumping forward" as I have on my lexus gx470. Should this problem not be corrected, I will sue under lemon law. I will write my legislators. I will write editorials to every newspaper in the region. I will picket dealerships on my days off. Should nhtsa and/or lexus/toyota neglect immediate attention to this matter, I will share my experience with investigative reporters. Why should my 4 year old have to sit in a vehicle that is unsafe? Why should my wife have to cry in a service department because her pleas for assistance go completely unanswered? Why should a cocky service manager call my cell phone to explain to me that I don't know what I'm talking about? Toyota now contemplates buying the failing gm as toyota fears possible american consumer & governmental backlash. If you have to recall vehicles, so be it. As 60 minutes' andy rooney would say, "...It doesn't take a rocket scientist to know there's a problem here..." Ladies & gentlemen, there's a problem here. We've paid top dollar for what are billed as superior vehicles. Live up to your reputation & fix the problem.
