Intake Manifold Leak?

[Hibolt]

my 2002 galant 2.4L recently had its intake manifold replaced cause it was cracked at the flange I also had the motor mounts replaced. 6 months later it cracked again what is the main cause of this problem to prevent this from happening or is this truely a design flaw? this is really starting to take a toll on my wallet.
