Service bulletin 21-396

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

This is an email sent to dealers for advisory 21-396. It has been determined certain Voltage-Yukon trailers may have defective self-leveling roof sealant that exhibits a hard, cracked appearance. The defective sealant exhibits poor adhesion and cracking within 96 hours of application and can be easily removed from the roof by pulling it up by hand. A visual inspection will reveal the defective sealant lifting from the roof due to poor adhesion properties. Campaign closes May 30, 2021.
