Audible engine "Knock" On Start Up

[T4Argh]

Alright....anyone else experience this? I can hear knocking or pinging after a cold start. The sound is heard mostly while on idle but completely goes away when the engine is up to operating temp.

Should I be worried?

Do you have aftermarket skid plates?

Do you have aftermarket skid plates?

Everything stock (2013 Limited) minus the wheels and tires.

Mine did it on the 2011 SR5 from day one to the day I traded it with 66K miles. My 2012 TE does it too if it's really cold. I am not worried.

There's no way to know for sure we're talking about the same noise, but my 40K 2010 does make a knocking noise and so does my brother's brand new 2014.

Mine does it as well. There are times I'm in idol in a drive though and it sounds like a quiet diesel.
