If it is cold when you start up, and then the car interior warms up and that is when the 'rattle' stops, I would say it is normal.
I've had in every car I've ever owned. If you think about it, it has something to do with co efficiency of linear expansion. Most plastics and metal shrink and expand by the temperature change, and they do so differently based on the composition. I guess if everything was bolted tightly together all over the car, then it wouldn't be noticeable. But that is not the way cars are put together.
I think of these noises as more like a 'squeek' than a rattle.
But this is all just my opinion.

Best thing to do is to sell it, and just take the loss. Over a lifetime, no big deal. I bought an 07 Avalon XLS in Aug-Sep timeframe. At first, no noises or rattles. Now and for several weeks, when the temp is in the 40s or below, I have the most annoying rattle. But it's coming from the sunroof. It stops if I press up and hold the force on the sunroof. The dealer confirmed its the sunroof. (Sounds like it's coming from the dash or maybe passenger side of car.) The dealer has ordered a new frame and housing or something another and says they know what to do-involves dropping the head liner in the car. First time in 20 yrs I've ever taken a Toyota in for anything under warranty. Have n 04 Highlander also. Toyota has over the years cut costs and cheapened construction & materials. Probably will my last Toyota buy. Geo

I did change those struts and still the noise is there! That has to be something else.

I had a similiar problem with a Avalon 2000 XLS. I installed four new struts. Then everytime I hit a bump in the road I would hear a right front thumping noise. Surposely, the shop that installed them checked everything(twice)--struts, mounts, front-end, tires, retighten, etc. No luck. Even took it to the Toyota dealership and they cound not find the problem. Took to another shop(same company that installed the struts) and found out the right front mount was cracked. They installed a new mount and warranted the right front strut since thought maybe it was also damaged. Now it rides, drives and sounds like new!
 
  If you did not install new mounts I would sure check them out. The guy that fixed my car said the mount was usually the cause of front-end noise problem after insalling new struts.
 
Good luck!

strut tops by memechanic

I guess they call it "strut tops" or some like that. It looks like there is not much to it and very unnoticeable for anyone unaware but the cost is like $600, an estimate I got. So, I am not sure if he included all the other adjustments like alignment that has to be done as well.
Thanks much,

have an '05 xls and have a rattle on the right topside of the dash,but this only occurs when i hit a hard bump.
 have noticed many comments about toyota quality..my car has 20000 miles and picked it up from the dealer today for 3 warranty fixes..all of these problems had service bulletins issued on them,so they must be common problems.
1. noise(rattle) in the rear of the car seemingly near the rear of the seat..apparently welds have broken loose.
2.on acceleration,the sulfur smell is overpowering with the roof open..replaced exhuast pipe and cat converter.
3.drivings lights were loose..there is a replacement holder for these..
 
still have to resolve :
4. headlights stay on too long after the car is shut down.
5. rattle in the front dash
6. front bumper cover has pimples,i.e. when you rub your hand over the cover it is rough and there are probalby 150 very small "pimples"..dealer said stone chips and i told him i couldn't get that many chips in a 100 yrs. of driving..besides,chips take out paint,not cause a raised surface..this one looks like court..
 
 i feel with this car i have bought a gm or ford with 100,000 miles on it..it serves me right that i tried to save some money by buying the avalon and not replacing the LS400 which i still have ..that was a car..!!

I hava a 04 Solara that has driven me bonkers for 11 months. In cold weather (below about 40) I would get a rattle from the front right side of the sunroof (AKA moonroff on this board). Slight upward pressure on the glass would stop it. Problem would sometimes come and go suddenly. Sounded like a teletypewriter at times. Dealer pulled the head liner numerous times trying all sorts of fixes. Finally, I guess with Toyota's blessing, ordered, and intalled a new sunrrof,or at least new tracks and I assume frame. Told me they drove 300 miles and saw no problem. So far I have done 20 miles and no problem, but this is not a guarantee since after the last "fix" the noise returned after 70 miles. I have heard that the Avalon and Solara roof are not identical but have some similarities. Good luck with your car. If the new sunroof does the trick please confirm and knowing what it was about the sunroof that the dealer feels caused the problem could be very helpful in case my problem returns. I am keeping my fingers crossed.
 
Thanks,

Precisely the problem with my 07 Avalon sunroof. Exact same spot and scenario. Dealer has ordered and has in a new frame, housing and all. They will drop the headliner and install new parts. They have done this before to fix the problem. I plan to schedule running it in this week. Good luck with your fix holding. Will advise results. Am reluctant to do this, realizing it can cause other problems I don't have but when the noise comes it's nerve racking. gpciii

I own an 05 Avalon Limited and most of my post during the past two years have been with respect to rattles. Most have been resolved, but the most annoying and loudest one continues to be the moon roof rattle, which occurs on temperatures below 40 degrees. As I posted last year, the rattle goes away when upward pressure is applied to the moon roof on the front passenger side.
 
Since I took delivery, my car has been back to the dealer a number of times and, on at least two occasions, it was in the service department more than a week. Everyone, including the service director and the local Toyota rep have heard this rattle, yet they can't seem to fix it. Last Spring they replaced the moon-roof assembly, yet this did not fix the rattle. Two months ago, they removed the moon-roof, applied insulation and replaced the headliner. Well, still no fix!
 
The dealership GSM has told me that they have done everything they can do and the GSM commented that all cars rattle ( inferring I should live with it ). That of course, is a response I would have expected from a US car dealer when they could not fix the problem, but not one I expect from Toyota, especially on a car with an MSRP of $38K+. This car has rattled every cold day from the time I took delivery. I again shared this comment along with my frustration with the GSM and service director and asked for them to set-up an appointment with the Toyota rep. That request was a month ago and I'm still waiting for that appointment. I spoke to the GSM this past week ( second call I had to make to him ) and he said the service director has a call out to the Toyota rep and I'll get a call once a date is scheduled. Well, I didn't receive a call on Friday and if I don't hear back tomorrow, I'll contact Toyota.
 
This is the 4th new Toyota I purchased ( Celica, Solara, Lexus GS300 ) and, with no exception, the most disappointing experience I had with any new car purchase - this includes, new other new car purchases as well - Honda, Mitsubishi and even my Dodge.
 
At this point, I'm not sure what the Toyota rep will offer to do. I certainly realize this does not qualify for a lemon law, but I want someone from Toyota to explain to me why this problem can't be fixed. This is either an engineering issue with the moon-roof or the service department is is unable to fix the problem. My guess it is the former and not the latter. In any case, I will no longer keep a car and cringe driving it every time the temperature drops below 40 degrees.
 
I'll keep you updated!....dan

Dan... a question for you..you say your rattle is coming form the moonroof. Is that the source of the rattle, or is that actually where you here the rattle. I ask because I have an 07 avalon xls and about 2 weeks back when the temperature dropped down in the 30's, I noticed this loud obnoxious rattle in my car. It sounded as if it was coming from the dashboard area, passenger side. Funny thing was as soon as the car interior warmed up, about 4 or 5 miles down the road, the rattle stops. We don't have alot of very very cold days in Louisiana but here's what I've noticed so far... on cold days, car's parked in the garage when I leave for work, no rattle... cars sitting in the parking lot on cold days, get in it to drive home, the rattles back, but goes away when it warms up. Like I said mine sounds like it's coming from the passenger side dash, but heck, it could be coming from anywhere. Keep me posted on how things work out with yours. Good Luck.
