One problem related to alternator/generator/regulator has been reported for the 2006 Lexus Rx400h. The most recently reported issues are listed below.
The vehicle surges at a steady speed. I am most aware of the surging at 35-45 miles per hour. This did not happen until the vehicle had approximately 8,000 miles on it. I have been told there is no repair available and the Lexus is aware of this problem.
