Saini Bhawan owners: Are post-possession quality issues real?

Honestly, I didn't think property buying would be this much of a headache. Saini Bhawan mein project dekha tha, brochure mein sab sahi laga. But now I'm hearing stories about construction quality post-possession. Cracks, seepage issues within a year... is this common? My parents keep saying builders cut corners. Jab itna paisa laga rahe hain, toh kya good quality expect nahi kar sakte? Anyone here faced these issues with Saini Bhawan or similar projects in Chandigarh? What did you do?
