# Service bulletin 540214

A bulletin is a manufacturer's communication to its dealers, as NHTSA indexes it. The summary is NHTSA's. The document is the manufacturer's: read it at NHTSA. A bulletin is not a recall, and listing a model year does not mean every vehicle of it is concerned.

- Type: Service bulletin
- NHTSA id: 10148325
- Published by NHTSA: 2018\-11\-13
- Manufacturer's number: 540214
- Manufacturer's date: 2014\-05\-01
- NHTSA component: VISIBILITY:SUN/MOON ROOF ASSEMBLY

## NHTSA's summary

The sunroof does not close. This only occurs after the sunroof is left open for an extended period of time while the vehicle is parked in direct sunlight. The sunroof seal expands when exposed to the sun and becomes relaxed. This causes the sunroof glass panel to go into "anti\-trap" mode during the closing process. This issue affects P/N 54 10 7 271 623.
