Sunroof leaks by make
Sunroofs leak the same way on almost every car, so most of this guide applies whatever you drive. This page covers the shared pattern, points to the model-specific guides, and clears up the two things most often mislabeled as a "sunroof leak": other water paths, and spontaneous glass shattering.
The pattern is the same on every make
A sunroof is built to let some water in and drain it out through four corner drains. A leak almost always means a drain is clogged, or a tube has slipped off its fitting, so the water backs up into the cabin. Clear the drains gently and you fix most leaks on any car. See cleaning and testing your drains for the universal method, and remember: never use high-pressure air or stiff wire. The tubes are a slip fit, so both can pop a tube off inside a pillar or pierce it. (General Motors' own service manual caps drain-clearing air at 35 psi for exactly this reason.)
It is often not the sunroof at all
On many cars the "sunroof leak" is something else, because water travels far from where it enters. The usual impostors: a blocked air-conditioning condensate drain (wet floor when the A/C runs, no puddle under the car), a clogged cowl drain at the base of the windshield, a windshield bond, body seam-sealer voids, or roof-rail and tail-light seals. Confirm the source before taking the headliner apart. See find your leak.
Glass shattering is a different problem
Some makes have had panoramic glass spontaneously shatter. That is a glass and tempering issue, not a water leak, and is unrelated to drains. A few genuine recalls exist for glass that was poorly bonded and could detach (Hyundai Veloster, certain Subaru moonroofs), but most "exploding sunroof" reports are owner complaints and lawsuits, not recalls. If your glass cracked or shattered on its own, that is a separate safety topic.

Volvo and BMW get their own full guides (the seal-gap fix is specific to them). Most other makes are a drain-maintenance story, so the tool that helps is the drain brush, not a gap filler.
