# Service bulletin SB\-72

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.

- Published by NHTSA: 2024\-07\-01

## NHTSA's summary

It has come to Tiffin Motorhomes attention that on certain 2023\-2024 Convoy and 2023\-2024 Tiffin GH1's, the wrong coolant for the AquaHot system was used in production. Over time, corrosion to internal aluminum components and premature failure is likely.
