2011 Jeep Wrangler Question: Is it possible to stop leaks at the A pillars of the Jeep Wrangler Unlimited?

Leaking noticed after a year when Jeep was parked outside during overnight rain. Jeep had always been garaged until then so fault not noticed. Dealer has had an attempt with additional rubber and foam. Not successful. Second attempt being arranged. Warranty has 21 months to run. What if leaks still happening then? I've dried carpet each time leaks occur. No permanent damage yet but not using vehicle to travel in rain as no way to dry when away from home. Quite disappointed that this new vehicle has such an unacceptable flaw. Should dealer take vehicle back if problem not fixed as it does not serve purpose it was sold for.
