Water Leak Into Cabin
Has anyone had an issue with water leaking into the cabin? I sent my car for a small leak into the cabin which I thought was coming from the windshield I had replaced, but appears to be coming from the sunroof drain. Got the car back yesterday and the dealer made it worse. I sent the car back to get repaired but the parts are on backorder. Has anyone else has a similar issue?

There are drains located in the sunroof that can get clogged causing water to pool in the roof and spill over. On my previous car, the dealer had to replace the sunroof and didn't reconnect the drain plugs... a few weeks later after the car sat in the rain the entire floorboard was wet and water was slowly dripping from each corner of of the door pillars.
