largo Posted November 14, 2008 Share Posted November 14, 2008 Any one figured out what those strange sound are that come from the RX400 about 5 minutes after you turn it off. Quote Link to comment Share on other sites More sharing options...
richard4u Posted November 14, 2008 Share Posted November 14, 2008 WHAT STRANGE SOUNDS ??????????????? my 2007 rx400h makes no strange sounds - perhaps it is the exhaust system cooling off - maybe a clamp is loose or too tight - can you be more specific ?

Gryphon Posted November 14, 2008 Share Posted November 14, 2008 There are words in the owner's manual about such sounds being normal. Tom Quote Link to comment Share on other sites More sharing options...
katzjamr Posted November 15, 2008 Share Posted November 15, 2008 this is the fuel system venting itself automatically. the first prius hybrid has a bladder for a gas tank which can be very frustrating to fully fuel, the next gen prius and toyota/lexus hybrids came with an automatic system that vents the fuel system allowing a normal gas tank to be used.
