True, the latches have sharp edges. I have noticed that even if the tape is damaged (creased/scored/squished), the noise is stopped. I'm looking at other materials now ... I will try a few other types of tape/coatings. I am just happy I found the problem. Even if I have to replace the tape regularly, I can live with that solution. It creates a more solid feel in the car. Pretty amazing that 5 cents worth of tape can create such an improvement in the car. I suspect that this is a common problem on the RX; many might not even realize that it is not normal.

Remember the tape is damaged, however, the adhesive remains. This is kind of a pad in and of itself which lasts longer than the tape cover. Think about buying something made of glass and taking off a price tag. BIG pain in the ****. So the adhesive can be your friend, in a way. A more permanent solution, and one that doesn't build up with potential problems over time would be best.

I finished my project to reduce all of the noise of any kind in my RX. In the end, I used this product on the door latch brackets:

http://gorillaglue.com/tapes.aspx

Plus, I added it to the trunk latch bracket also. The Gorilla Tape is tough enough for me and seems to do a good job. I think the 1" roll is a good size for use in the car.

Other noise reduction changes I made included: 1) taping all contact points on the little privacy shelf under the back window (I also considered just taking it out); 2) taping all contact points on the trunk package cover; 3) storing two of my extra cotton towels that match my car interior over the trunk package cover to provide a little weight to keep it in place and muffle any noise from it; 4) taping the contact point for the back seat bracket (in the seat backs) that holds the various upper back seat segments in place.

I had a slight rattle (almost sounded plastic) that would occur only when the vehicle was cold. After about 10 minutes it would go away. I asked the dealer about it when I was getting my d/s window replaced. The tech took it out for a spin and, of course, didn't hear a rattle but greased various parts of the door. Guess what? No more rattle. My assumption is I have the same issue to will be Gorilla taping the latches if it comes back.

By the way, I'm surprised that this problem is not experienced by more people. A problem like this can't be limited to only a few cars.
my car doesn't do that but the loud engine is just as annoying. drives me crazy! sounds like im driving a diesel truck!

Angry

I have a kind of "puppuppup" sound (difficult to describe) coming right by my left ear - but only at certain high speed/roads. If I press the seal around the window near to the seatbelt side it goes away. Very annoying. It is low volume and intermittent and do diificult for other people to hear.

HI UCSB. Thanks for the information. Could you please post some detailed pics to help the rest of us out?

Thanks!

Default My squeaks and rattles update

Today my 2010 RX's rattles and squeaks are gone (fingers crossed/knock on wood). I bought the car from NorCal but all the work so far was done at Carlsbad Lexus. OK, let's go back about a year ago...

2010: 1st issue - (non-rattle) driver side mirror motor, went bad - replaced. Bumper, dented! Fixed by dealership for free.
2011: 2nd - passenger door squeaks as you open/close the window - replaced entire door.
2012: 3rd - noise, rattle, and squeaks before releasing the brakes, while driving on uneven road, and awhile slowing down and coming to a stop. The annoying sound was like you're driving a loosely built go-cart, which you could hear and feel all the flexing and moving of the vehicle major parts. Well, the passenger door was disected, and additional padding and fastening was accomplished. I don't know what else they did but I hope all the noise is finally gone. I am trying my hardest to like my wife's RX but I might have to take my GX back from her if I keep getting some flexing noise.
2012: 4th - While checking for rattles, the dealership discovered feathering on the tires - alignment performed.

Default Another HUGE reason for road noise found!



As I was reading the body kits thread, I saw this pic. As you can see, there is no sound deadening stuff added on the wheel wells. My previous LX and with my other car, GX had so much rubbery like stuff aounrd the wheel wells the tire and road noise is almost non-existent.

How could Lexus not put even a thin coat of the good stuff on the bottom of the RXs, I really feel that we are shafted given the fact these vehicles are called luxury SUVs.

My question is..

for SoCal residents, do you know of any shop that does undercoating work to reduce road noise? I need to get it done or I'll be miserable driving this RX. Thank you so much for the help.

There has been much said about road noise in earlier threads but it seemed to center on what tires were on the car. Most of the issues I think were on Dunlops. I see in the photo you've changed your wheels and tires to a super low profile that's not a factory option. One has to wonder if that doesn't have something to do with road noise as well. Just saying ....

When ever you do mods like this, you have to expect the car won't handle/sound/be the same as off the factory line.
