Don't trust Jeep Cherokee

Don't trust Jeep Cherokee

I bought a Cherokee SUV 2017 new car at SerpaChrysier Dodge Jeep Ram on March 17, 2017.
But After 3 months, we back to their auto repair shop two times for maintenance. (water is leaking from sunroof entering into)

Finally result is :
service advisor and salesman Mr. Jxx told me that, they can not fix it because this is not their fault; Jeep Cherokee make a wrong design; this model should be like this; this model design make this problem(s) .
So they can not do anything.

Please, anyone can tell me what should I do now

Today is rainy day (Nov.,4 2017) water is leaking never change.

Dear my friends.
