Symptoms
Water dripping through the overhead console with the roof shut, a damp headliner or passenger footwell, or a musty smell after rain. NHTSA complaints include a rear section of the sunroof that doesn't seal and a cabin that smells of mildew every time it rains.
The fix, step by step
- Open the roof and clean out the housing, especially the corners where the drains are.
- One LandCruiserForum owner found his corner drains plugged with leaves and plant matter, so water overflowed into the headliner.
- He cleared it with rags, a shop vac and compressed air.
- Keep the seals clean and the drains clear.
- If water still gets in once the drains are clear, it's a warranty job: UK owners report dealers removing the glass and fitting a new seal under Toyota's instructions, and one says his dealer found a TSB involving new sealant (no number was given).
- Some trucks needed more than one visit.
