The National Highway Traffic Safety Administration said that road salts can cause "excessive corrosion" of the Toyota Tundra's frame, which holds a spare tire mounted underneath the vehicle. NHTSA said dislodged spare tires can cause hazards for other vehicles on the road.
The corrosion can also damage the rear brake lines and lead to brake system failures, the NHTSA said.
The agency urged Tundra owners to remove the spare tires even before taking the vehicles to a dealers to be remedied.
