Hybrid TechnologyUnique topics related to the 2004 -2009 RX400H model hybrid drivetrain and other features/options found only on the RX400H. Please use the main forum for discussion about shared components with other second generation RX models.
The last of the RX400h was 2008. If you have a 2010, you have an RX450h and you posted your question to the wrong forum. You want to post to the 3rd generation forum.
