Warning - Broken control arm bolt!

[Lafiro]

I have this noise as well. Its actually very loud over some bumps. I just received a ZTU about this in the mail that Toyota will now cover the defect on late 2006 to early 2009 Yaris with up to 7 years and under 100,000 miles. Too bad I am at 117,000 miles.

Also, with the car off, I can push it back and I hear a loud squeaking sound as well! What in the world is this now? Could it be the control arm bolts just moving and producing the same sounds as over bumps? Or this is something completely different?

I also noticed a new noise. Its like a metal on metal vibration when the car gets warm/hot (even now in winter). As long as the car is in Drive and at a stop, it vibrates loud. Same again when first accelerating from a stop or at a low speed. What can this be?

Can someone help me please. I can't figure these out.

The control arm bolts are easy to check. Even if you can't jack it up to take a look, you can at least feel for them. The pictures below shows where the bolts are located and what the bolts runs up through.

With the pushing back sound, if the bolt broke it could definitely be that.

The metallic sound may be from one of the exhaust shields having pulled through the head of the mounting bolt.
