One problem related to transmission failure has been reported for the 2007 Lexus Gs450h. The most recently reported issues are listed below.
Air bags - Lexus refused to cover under warranty deployed airbags due to lightly scrubbing a curb power train - the auxiliary oil pump on the automatic transmission failed, as it is commonly known to do. The bearings inside the pump wear down over time and eventually sieze. This leads to the vehicle being limited to 70 miles per hour as well as disables the hybrid system. This triggers mil p2797.
