# Service bulletin NTB21\-014

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

2012\-2015 TITAN; HIGH\-MOUNTED STOP LAMP SERVICE PART SERVICE INFORMATION The mounting stud diameter for the high\-mounted stop lamp service part has changed from 5 mm to 6 mm. If, for any reason, the high\-mounted stop lamp needs to be replaced, the mounting hole will need to be enlarged to 6.5 mm \(¼ inch\) as follows: 1. Remove the high\-mounted stop lamp. • For high\-mounted stop lamp removal, refer to the Electronic Service Manual: Section DRIVER CONTROLS \> EXL – Exterior Lighting System \> HIGH\-MOUNTED STOP LAMP \> Removal and Installation \> HIGH\-MOUNTED STOP LAMP. 2. Enlarge the high\-mounted stop lamp’s mounting holes \(see Figure 1 on page 2\) using a 6.5 mm \(¼ inch\) drill bit. To avoid damage to the vehicle, apply light pressure to the drill while drilling. Excessive force may cause the drill bit to penetrate too far and damage the headliner. 3. Apply touch\-up paint to the mounting holes to protect the bare metal. 4. Install the new high\-mounted stop lamp using M6 mounting nuts. Refer to the PARTS INFORMATION on page 2.

- [NTB03074J](/bulletins/10192750.md), 2021-05-10, Service bulletin: EXTERIOR LIGHTING. SERVICE INFORMATION Occasionally customers may notice water vapor or fog in the headlamps. The information, illustrations, and flow chart in this bulletin are provided to help you in determining if an incident for water/condensation in the headlamps is normal or not. Nissan?s new vehicle limited warranty does not cover physically damaged \(cracked or broken\) headlamps. All current headlamp assemblies are vented to the atmosphere \(not sealed\). \- This is necessary to allow for expansion and contraction of air from temperature "variations" \(warmer or colder\) without damage to the headlamp. \- Moisture in the air sometimes "travels" into and out of the headlamp assembly through these vents. \- Certain environmental conditions may cause moisture to condense. \- The fogging/cloudiness should disappear over time when the headlamp is in a dry environment. See this bulletin for further detail.
