CONDITION
Some vehicles may experience a condition in which the drain hoses for the sunroof/moonroof assembly
become kinked, or pinched. This may cause water leaks into the cabin from the housing assembly drip trays, or
the customer may note water stains on the headliner assembly.
RECOMMENDATIONS
The material used on these hoses will retain a shape memory once pinched, kinked, or damaged. Therefore it
is important that vehicles experiencing this condition, receive replacement service part drain hoses that have
not been kinked/pinched/damaged during storage or shipping and are completely clear of any shape
abnormalities.
When replacing the damaged drain hose, it is also important to ensure that the hose is installed correctly and
oriented as shown in the example below to help prevent a kinked condition from occurring again.
