bongt Posted December 31, 2006 Share Posted December 31, 2006 I have an 2002 rx300 (50k miles), recently I noticed a loud humming sound when accelerating. No noise during idle. Anyone experiencing the same problem or have any advise as to how to correct the problem? Thanks. Quote Link to comment Share on other sites More sharing options...
jesterlives Posted February 1, 2007 Share Posted February 1, 2007 I just posted in this forum a few days ago about this same issue! I get a loud humming noise that occurs when accelerating at normal speeds...it happens from 40-44 mph. It happens when I accelerate and decelerate...always at the same speeds. I have no idea but I am taking my 99 RX300 in for a new oil gasket....so i am going to try and get an answer from someone. I will let you know.

NewportLori Posted June 6, 2007 Share Posted June 6, 2007 Unfortunately from current personal experience, I've learned that this humming sound during acceleration in the lower gears can be a sign of transmission failure. Quote Link to comment Share on other sites More sharing options...
