#1 of 85 Noise in right rear 05 Avalon
Aug 28, 2006 (6:44 pm)
I have an 05 Avalon limited and am experiencing a popping noise from the passenger rear. It happens when turning (right most of the time) and when the back springs are being depressed like in going over a bump or hitting a depression in the road.
Anyone else experiencing anyhting similar?

My Limited has been in the shop a number of times to get same rattle fixed and back last spring, the rattle was finally isolated and was found to be coming from the right side of the moonroof. To see if this is the source of your noise, when you hear the rattle, apply upward pressure of the front portion of your moonroof and, if it goes away, then you know the source. Unfortunately, I have had my Limited back to the dealership a number of times to get this resolved. I even had a Toyota rep meet with me and he acknowledged the rattle. Although I thought this was finally fixed last Spring, it has now returned. The rattle always occurs during "cold" periods, so my guess is that it was never fixed and now that the mornings here in New England are becoming cool,I have to get this addressed again. Good luck! dan

Does anyone here know if the 05 Avalon Limited has an electric fuel pump that is located in the rt side of the tank?
I get a pulsating noise just after starting and it sounds as if that is what it may be.
At times I get it before the car starts to move, so I am assuming a fuel pump?
#4 of 85 Dashboard noise

I have an '06 Avalon XL and I've been noticing a squeak/rattle somewhere in the dashboard area when going over bumps. The car was very quiet when I first bought it a year ago, but I started noticing the noise a month or so ago. I'll probably have the dealer look at it during the next oil change, but in the mean time, has anyone else experienced this and do they have any suggestions? Thanks in advance!

Yes and they finally found it. I alos thought it was in the dash but it wasn't. After trying a rear strut TSB that didn't work, someone on this forum told me to have them check the sunroof. That was the problem and it is now fixed.
It took three days to fix it and they ripped the headliner which they had to replace. I made them give me a loaner free of charge.
Too little, too late I was so sick of bringing it to the shop I traded it on a new 06 Acura RL.

It is in your dash because I have the same problem also. It only occurs if the tempertaure is below 40 degrees and it does not occur all the time. I've had this same rattle last year during the winter. I was able to determine that one of the rattles was coming from the pillar speakers. Toyota fixed it with some foam tape but now the rattle is back again. I'm just turning the stereo louder to drown out the rattles.

I have an 07 Avalon. Toyota hasn't learned anything. I have this noise. It sounds as if it's coming from the dash but sometimes from the passenger door. And it's when the temp is in the 40s or below. None when car was new. After about 2000 to 3000 miles it came. Not all the time - viturally none when warm outside to almost all the time when colder. Rough road or smooth it's there. I haven't had the dealer chase it yet but plan to. Will try moonroof as source as described in this email chain.

Just wanted to add note that I've never had a bothersome noise such as this with any Toyota dating back to 85. This is the most expensive model (07 Avalon) I've bought and so far the worst as far as little nuisances, e.g. windshield wipers squeaking right out of the chute, 2nd master key lost in dealer transfer and new one having to be made, missing an instruction manual.
#9 of 85 Passenger Side Noise '99 Avalon
Dec 22, 2006 (8:42 pm)
I own a 1999 Avalon, 125,000 miles, and have a thumping noise on passenger side of vehicle. Sounds like the muffler pipe is thumping against the undercarriage when going over small bumps around the passenger seat. My garage says the muffler is attached securely and isn't causing the noise, and that nothing is loose. Any ideas? It's been going on for over a year. I had a problem with the air/heat fan making a ton of racket and my mechanic popped the cover off the fan under the dash and found a mouse nest that caused the circular fan to be off balance...disgusting...he says it happens all the time and that the little critters pull the insulation out of various areas which might be causing the thumping noise...doubt that as the thumping sounds pretty heavy. I'm thinking now from discussions that it might be the speaker in the door. I'll have to check that out with my auto body shop.

This problem has had previous press in the Avalon forum. One of the things mentioned and you may not believe it is the passenger front seat belt. It has been known to hit the sides of the seat and center post the belt is mounted on. Make sure the seat belt is fully retracted. To test this theory, fasten the seat belt together and see if it goes away. Another method is asking yourself does this rattle occur when a passenger is riding along in the front and if so, are they wearing their seat belt? If they are and no rattle then there's your answer. Another rattle that can seem to come from different places inside the cabin is if you have a moonroof, open the ceiling cover and while your riding over bumps and hear the rattling, place your hand on the glass and put a little pressure on it and see if it stops or not. 3rd thing known is when no one is sitting in pass seat, grab it and see if you can wiggle it. There should be very little wiggle room. If there is a lot, you need to tighten it. There is a Toyota service bulletin on that. Last but definately not least is check the struts and mounts. The main top strut center bolt is known to loosen up anywhere from an eighth to half a turn over time and cause big time rattle. This happened to me. The mounts are also known to go. You are roughly at the mileage for these things. Hope this helps. Let me know how you make out.

Long Live The Avalon!
