## NHTSA's summary

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.
