Any Nissan Mechanic's In Here ???

We have a 2013 Nissan Sentra we bought new... Every since we have had it, on cooler mornings it rattles pretty bad for a few mins, sound like loose rocker arms on an older car... My 2002 truck only makes a small sound for like 4 secs and sounds way better than this car... During the day its ok... We had a Nissan Versa 2012 with a 1.8 that also did the same thing, and I told them for a year something was wrong.. One morning was doing the same thing and never stopped...It had to have a long block replaced.... Seems like this car is doing the same thing...Its had all oil changes and took very good care of.... Any tech know if this is a common problem ??? We ask the dealer and he came back with a answer, may-b some dirt got in the engine..... I wouldn't even reply to a stupid answer like that , I told my wife she could talk to him....

Does it get louder with engine rev? That's pretty new to me, never heard that sort of sound before. Hopefully someone else can chime in as well.
