"Overloading your vehicle may adversely affect handling and braking and may cause tire damage, resulting in tire failure and a crash without warning," says NHTSA in its recall summary of the problem. Hyundai stated that it has reduced the front and rear gross axle weight ratings by 66 pounds each for the Santa Fe models equipped with 18-inch tires.
Hyundai will mail the corrected warning labels to the affected owners with instructions. Owners will also have the option of having the label installed for free at dealerships. Hyundai has announced that there have been no accidents relevant to this issue.
