# Service bulletin 23\-01\-034H

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

In some areas, a vehicle’s underbody may exhibit corrosion due to road salt usage. As a preventative measure, cavity wax coating is applied to the internal surfaces of underbody components, and an undercoating spray is applied to the bottom exterior surfaces of specified underbody components. This bulletin describes the procedure to perform this preventative service on certain Genesis Sedan \(BH\), Equus \(VI\), and Genesis Coupe \(BK\) vehicles.
