It leak when it rains Haven't been able to reproduce leak with hose.Help
You have to start with where you have evidence. The sunroof has 4 drains. Two front, two back. Open it, and pour some water in the front channel with the car sitting level. Should drain out quickly right behind the front tires. If not, they are clogged or restricted, and you need to fix that. Rear drains, helps in testing if the car is parked with the nose slightly uphill. They also should drain pretty quickly. If not, pull the headliner down in back and see if the tubes are connected, then check and see if they're clogged. Roof rack is also a possibility. Unless it has an obvious leak, I'd still start with the sunroof first, depending on where the leak actually is seen. Good luck.
