007Butch Posted May 18, 2011 Share Posted May 18, 2011 I have a 2010 RX 350 with 25K miles. Last Fall the engine started sounding noisy like a diesel engine especially when the engine was cold. There is no loss of power, mileage or performance that I can tell. Lexus says the sound is normal, yet the RX350 service loaner cars don't make this noise. Any thoughts? 007Butch Quote Link to comment Share on other sites More sharing options...
klonny Posted July 21, 2011 Share Posted July 21, 2011 my 2007 does too, I actually don't mind it but they say it's because they switched from a timing belt to a longer lasting timing chain, which is a little louder. Quote Link to comment Share on other sites More sharing options...
LEXIRX330 Posted July 22, 2011 Share Posted July 22, 2011 my 2007 does too, I actually don't mind it Well that is the first thing! thing to look out for? yes the whole car. it sucks. worst "luxury" vehicle I've ever owned and I use the term luxury loosely. expect rattles, electrical problems, crappy stereo, next to useless 4wd the only nice is it looks nice on the outside. go MDX, Go ML500 even X5...but not this piece of crap.
