When I talked to a neighbor who also has a 2005 RX330 and mentioned that maddening rattle from the rear, he immediately opened the hatch, depressed the tonneau cover latches and said let him know if it fixed it. It did. Note you DON'T need the latches in the up position for the tonneau cover to work; all the down position does is disable the auto retract feature. But I like the auto retract function, and I'll see if I can get the dealer to make the permanent fix for me. Thanks guys!

 

I did exactly what you have done, this is not the permanent fix.
I did contact lexus hq first, they wanted me to have the dealer inspected first, if any problems call 800-255-3987, I have made an appointment this friday afternoon with the dealer will keep you posted.

 

went to the dealer yesterday afternoon and the dealer insisted on $110 for the work to be done since my car is out of basic warranty, called the 800 lexus number a long wait for 30 mins, have to call some other day.
May have to buy the parts on my own if nothing comes out of lexus, how are the parts look and how easy to install ?

 

did you have them inspect/diagnose it? or just verbal quote? which dealer in IL did you go? and do you have extended warranty, was yours Lexus CPO?
let me know.
thanks

 

yes the Palatine lexus dealer inspected the car. no extended warranty and private party buy.

 

Called lexus about dealer charging the fix, looks like they are on the same side.

Get the parts and do the TSB by yourself. Should be a simple fix. Do you have a copy of the TSB?

 

There is no TSB.

Sounds like even using parts did not solve someone problem.

I just did get finished working on my 2007 RX (we call it the "rattler"). I had it to the dealer three times for rattles in the back, one fix was for them to put a bunch of leather conditioner between the split seat sections (covered under warranty). They charged Lexus for 1 full bottle of leather conditioner (~$25 at Lexus parts) used maybe a tenth of it and didnt even give me the remainder. Their other "fix" was the felt at the back hatch.

The rattles have gotten so annoying I finally decided to take matters into my own hands. I solved it with mine by buying some velcro "felt" and installing it at locations in the trunk sections where I could find looseness. One area was the prop up rod for the jack and lug wrench floor cover. I then had to add some to the two small compartments at the back of the jack and lug wrench cover where the "floor" rests on the plastic wells. The last thing I addressed was the ever popular retractable cover. Remove the cover bar, install some very small sections of the felt under the bar where it rests in the supports and on the front of the bar. So far no more rattles. Hard to say what will pop up once our warm weather comes around again.

Except for the rattles, 41,000 trouble free miles. The original Goodyear tires were total garbage and got to the point of hydroplaning to the point of very scary (still had tread left - above the wear bars) and no uneven wear. New Michelins at 40K made a substantial difference in the ride/handling of this fine (now rattle free) machine.
