One problem related to tank filler pipe and cap has been reported for the 2001 Chevrolet Suburban. The most recently reported issues are listed below.
The contact owns a 2001 Chevrolet Suburban 1500. In August of 2004, at 99,551 miles, the engine stalled while driving 55 mph. The vehicle shut off suddenly and was towed to a repair shop. The contact paid for the fuel pump and fuel filter to be replaced. In July of 2008, the fuel pump and fuel filter were replaced for the second time. The failure involved two defective fuel pumps that were placed on the vehicle. The first was replaced by a second defective pump. After the second replacement, the fuel pump failed again and the shop reimbursed the contact. The manufacturer did not assist. The contact decided to purchase a fourth fuel pump that was installed by an independent repair shop on July 1, 2008. There had been no other failures because the vehicle cannot have less than a quarter of a tank of fuel. Otherwise, there will be failures with the engine cranking and stalling due to the pump losing pressure from the lack of fuel circulation. The current and failure mileages were 188,000.
