Submission from re 2007 Lexus LS460, has a defect which could cause a crash or could cause injury or death the consumer stated his local dealer has tried unsuccessfully to correct an intermittent and unpredictable hesitation on acceleration and then a sudden lurching forward. Recently, while driving 45 mph, as the consumer accelerated, the vehicle stalled for several seconds, the tachometer revved to 5000-6000 rpms as if the transmission was in neutral and then the vehicle suddenly and unexpectedly lurched forward, as if the gears re-engaged to about 65 mph. The same thing occurred many times before, but at lower speeds.
