Noisy 2009 Toyota Corolla

My 2009 Corolla has aprox 90,000 miles. It has recently started making a noise when I start it up. It is usually when it has been sitting overnight, or for a long period of time. I know someone with the same car, and her’s is doing the same thing. Anyone else having this problem or have any idea what this is?

Can you record the noise?

Can you describe the noise?

Can you tell us if the noise is coming from…
under the hood…
underneath the car…
inside the dashboard…
from the rear of the car…
??

You probably have the problem with the camshaft gear making a rattling sound on start up. It goes away when oil pressure comes up. Google the Service Bulletin and you can read all about it. (T-SB-0087-09 - March 13, 2009)
My 2009 Corolla occasionally does it in cold weather.
