Rising gas prices are also blamed for falling truck sales in the United States.
Korean automaker Hyundai says sales are so bad that it's cancelling plans to roll out a new pickup truck in 2011.
The company is abandoning designs for a mid-sized pickup that would have shared the body structure of a newly-designed Kia Sorrento sport utility vehicle.
Hyundai says its considering building a passenger car in lieu of the pickup.
