Service campaign 20-0033

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

During the initial phase of series production of the YT193 DOT vehicle, Terberg implemented several product improvements aimed at enhancing reliability and uptime: - Aftertreatment System Cover: The shape of the cover has been redesigned to prevent contact with the air inlet. - Air Intake Noise Damper: The damper on the compressor air intake has been reinforced to better withstand vibrations and improve durability. To ensure these improvements are applied to vehicles already in the field, we are launching a campaign to retrofit the updated components. Some vehicles were already equipped with the improved noise damper during production. Therefore, the attached VIN list includes a column indicating whether the noise damper requires replacement for each specific vehicle.

The document is the manufacturer's. This site does not hold it. NHTSA files a document at one of these two addresses; we have not asked NHTSA which.
