The recall is due to a potential defect in the hood that could cause it to detach while being driven. Some of the H3s from these model years have integral clip-tabs on the hood’s louver that may fracture. In these cases the hood louver could rattle against the hood and come loose. Gone unaddressed, more clips could fracture and the hood could come free while the vehicle is in motion.
If the hood comes free at any decent speed, it would become a dangerous projectile that could strike another vehicle.
Dealers will use an adhesive to secure the hood louver to the hood free of charge. Owners may contact Hummer at 800-732-5493 or NHTSA’s hot line at 888-327-4236.
