Five months before the new 2002 Lexus ES hit showroom floors, the company's U.S. engineers sent a test report to Toyota City in Japan: The luxury sedan shifted gears so roughly that it was "not acceptable for production."
The warning was sent to Toyota Executive Vice President Katsuaki Watanabe on May 16, 2001. Days later, another Japanese executive sent an e-mail to top managers saying that despite misgivings among U.S. officials, the 2002 Lexus was "marginally acceptable for production." The new ES went on sale across the nation on Oct. 1, 2001.
In years to come, thousands of Lexus buyers would discover firsthand that the vehicle's transmission problems, which caused it to hesitate when motorists hit the gas, or lurch forward unintentionally, were far from fixed.
