My car is still at the dealer since last Thursday.

I guess they had someone come out to look at the vehicle yesterday and they are going to work on it today. I'm curious to find out what's wrong with it.

Default Noise

It could be the weights in the rims. I had a similar problem. They may need to be tightened.

I took mine in too last weekend. The service advisor said that F Sports have been coming in with noises and they isolated it to the brake pads. They are aware of the issue but there has been no fix nor service bulletin issued from TMS.

My dealer still has my car. It's been there since last Thursday.

They were told by lexus to disassemble, grease it, and reassemble the rear brake system. Apparently the sound went away from the rear but they found noise coming from the front brakes. So they going to repeat the same for the front brakes tomorrow.

On mine I notice the sound after the dealership fixed the squeaky brake noise issue. They turned the rotors and change the break pads. Own my car It sounded like the brake pads are loose and I can really hear it bad going over bumps. I drove over the same bumps, applying light brakes and the noise go away.

Can anyone provide the brake pads part number that will fix this issue?

I thought the sound was only coming from the back but apparently it comes from all 4 wheels.

It's easy to fix. It took my dealership 6 days to find & repair.

I have taken my car last Thursday, and they told me the same thing about greasing!!
I don’t mean to disappoint you, but that will not fix it
Coz my car still makes the noise, now i have taken it to a different level and made a compliant to customer rights.

I hear a metallic clanging sound when hitting a pot hole. I checked around the rear black valence that houses the chrome exhaust ports. If I lightly bang around the area of the chrome exhaust trim, I hear the sound. I'll have it checked at my 5000 mile service. I don't have an F Sport.
