Dear Vibe Owners, I have read of several other owners also having difficulty with Water leaking from headliner at the joints with front roof pillars, in cars without the sunroof.
In my case, I finally went to an auto repair shop that specializes in fixing leaks. After a few seconds the expert there informed me that my windshield had been replaced and improperly installed. He quoted $200 for taking the windshield out and installing it again. He also said that frequently when taking the windshield out, it would be damaged, and have to be replaced, quoting $350.
I bought silicon caulk and filled the 1/4" gap between the top of the windshield and the roofline. I have had no leaks for the past month.
