Summary

16147 01 - Customer Satisfaction Program. On certain vehicles, the center high mount stop lamp (CHMSL) fasteners may back off over time and cause a water leak, allowing water to flow into the rear compartment battery tub. When the battery tub fills with water to a height of 50mm or more, the DC/DC converter module board and connector are exposed to water which may cause corrosion. If water drains below the DC/DC converter, a resistive short may occur on the printed circuit board which could result in an unattended fire when the DC/DC converter is powered. Dealers are to inspect for water damage in the battery tub electrical components, and replace the CHSML gaskets and nuts.

Owners of these vehicles have filed 92 complaints in the electrical category.
