It may help shed some light on loose coupling.

what is meant by Loose coupling and its problem?

Loose coupling is the SOLUTION to a series of problems, the looser the better.

Tight coupling, basically means something made up of ttwo or more parts, where the parts can NOT be used individually.

class Driver
{
     public Car ar;
}

class Car
{
}

Driver is tightly to Car, and can not be used without it.

I would say that what you are talking about is a difference between association and aggregation. As I understood loose coupling vs. tight coupling, it is about a knowleadge of specific type of associated object, so the client rely on the specifict type (tight) rather that on its contract (loose).
