should I be worried????

[duncan21]

last month i bought my 2008 nissan altima sedan. it runs great and i love it. while driving around i decided it would be fun if i tried out the cvt. so i drove it in the streets and highway...well in the following days when i start the car in the mornig my engine makes a really weird noise. it's hard to explain but it almost sounds like its struggling...is this normal since the engine is new or should i go to the dealership before the problem gets worse? or has anyone else experienced this problem?? thanks guys

I'd say go get it checked anyway. It wouldn't hurt 2 have it checked and since u say its 2008 hopefully waranty will cover it.
