The silver Jeep Cherokee was abandoned along with a makeshift ramp by suspected smugglers and discovered early Tuesday, U.S. Customs and Border Protection officials said.
When the SUV was driven up the ramp it got stuck when it became "high-centered," with its chassis stuck atop the fence between the front and rear axles.
Two suspects fled into Mexico.
After pulling the vehicle down, agents seized it and the ramp, the news website Azfamily.com reported.
