Is it normal to hear creaking coming from the rear at low speeds especially over bumps? Sounds like the creaking is coming from seething suspension related.

Anybody else experience this issue?

 

Sounds like it might be noise coming from suspension bushings. Colder weather oftentimes makes bushings creak...

 

i had the same problem and thought it was suspension related but it turned out to be my sunroof was loose...if you put your palm to your sunroof while it is closed and it moves then your sunroof is loose... i know it prolly doesnt make sense but i didnt believe it either until a lexus technician pointed it out... also another way is if you hear the noise with your sunroof closed but you dont hear the noise when it is open then the sunroof is loose

 

This week I noticed the new creaking noise from the back as well, sound like from rubber or leather part not clanking from metal.
Hopefully BC is right, because I don't want to deal with suspension parts.

 

I pushed on my sunroof glass and nothing abnormal, could not replicate the noise. Did you have a creak or was it more of a rattle/tapping sound? I did replace the sunroof glass gasket myself for wind noise.

I have the 450h so most of the time at low speed the car is in all electric mode, so I hear nothing else except for this creak.

 

Please update this thread if you get it resolved. Our rear end looks like it has a lot of bushings.

 

I will look in to this noise this Tuesday during car wash.

 

if i moved my sunroof left to right with my hand it would make a creaking noise... but for some odd reason when I drove the car it sounded like a rear suspension problem...I know it sounds kinda weird but having my sunroof tightened solved the problem right away

 

How are you moving the sunroof left to right? With the sunroof closed I push on the left side of the glass then right, nothing abnormal. I tried pushing the frame of the sunroof left to right.

 

Ha... No creaking noise today, but I didn't drive much today, under 20 miles, around 30 mins.

Tomorrow, I will sit at the back and let my gf drive, for sure she will drive over couple pot holes and the noise will come back alive.

 

You probably had a warmer day. Wait until another cold front comes in and see if you hear the creak noise again. Even cars that are just a few years old can have rubber bushings that get hard and sometimes creaky when they get cold.

 

It is most likely the sunroof. I too had a creaking noise from what sounded to be the suspension and after the dealer replaced a bunch of suspension parts, it was still there and ended up being the sunroof, which they replaced and it solved the issue.

 

That's an immediate divorce in this house.

 

Pesodos, I couldn't pinpoint the creaking noise, tapping around didn't help either, and the problem is the noise not always there when hit the bump/holes, and I barely here it now. May be like BClexus said above, the temperature effects the bushings and creaky.




lol no, she doesn't like to drive my car, for her, GS is harder to drive than her Rav4, and she love to be the passenger more than driving.
I know her problem is not look at the road conditions ahead, just stay in middle lane most of the time.

 

I drove on a gravel road and the car was creaking like crazy. I'm starting to think it's the rear sunroof area. When the weather gets better I plan on dropping the roof lining and replacing/re-tightening the sunroof nuts:

Another issue I discovered.
I pushed on my trunk lid and noticed it makes a squeaking sound. I think the cold weather makes the rubber seals squeak.

I plan on cleaning all the rubbers seals in the door frame, window tracks, trunk lid, and sunroof.
Then applying some silicone grease to all the seals.
