2012 town & country knocked

I have a 2012 Town and Country. It will knock one time when I start the vehicle. It will only do this on the first start of the day. Do you know what could cause this.

By knock you mean valve chatter/pinging? Might try running a tank of premium fuel with a higher octane to see if it makes a difference. https://www.yourmechanic.com/article...-engine-knocks
