# Service bulletin 09\-032\-18\-3483

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.

## NHTSA's summary

Some customers may complain of foggy rear combination lights \(as shown below\) after a car wash or heavy rain. This concern may be caused by water entering into the rear combination lights through the ventilation tubes. To eliminate this from occurring, the ventilation tubes have been changed to a ventilation cap design.

- [09\-003\-19\-3555a](/bulletins/10154529.md), 2019-03-20, Service bulletin: EXTERIOR LIGHTING; EXTERIOR LIGHTING:HEADLIGHTS; EXTERIOR LIGHTING:TAIL LIGHTS. Some customers may complain of condensation/fog inside the front \(headlamp/headlight\) or rear \(taillamp/taillight\) combination lights. The recent new models have been fitted with a clear lens which can cause the symptom to be more noticeable, however, it does not affect the performance of the light. This condensation/fog is a natural phenomenon that occurs when there is a fairly large temperature difference between the inside and the outside of the light housing. It is normal for very small water drops to appear in certain locations on the light units where the air is stagnant \(condensation\), making the lens look whitish \(fog\). This happens mostly in the corners and narrow spaces, and will typically clear during warmer ambient temperatures, or when the lights have been on for some time.
