# Service bulletin 07\-139\-18R

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: 10144875
- Published by NHTSA: 2018\-10\-01
- Manufacturer's number: 07\-139\-18R

## NHTSA's summary

This bulletin outlines a design change made to the inner lens extension portion of the LED headlamp assembly. Under the right conditions, the shape of the lens for the actual head lamp light source can cause sunlight to be focused onto the extension portion of the lens resulting in deformation. A heatresistant shade has been added to protect the affected area.

- [07\-111\-16](/bulletins/10111094.md), 2017-08-14, Service bulletin: EXTERIOR LIGHTING:HEADLIGHTS. This bulletin announces a design change to the headlamp assembly to improve sealing and prevent moisture intrusion. This condition may result from a slight misalignment of the attaching points during the headlamp assembly process. An improved sealing material is now being used for bonding the outer lens to the housing.
