Two problems related to tank filler pipe and cap have been reported for the 1999 Chevrolet Suburban. The most recently reported issues are listed below.
While driving and without any warning vehicle stalled. Technician indicated that fuel charcoal filter clogged the tank, causing gas to leak. Manufacturer stated fuel system failed because of poor maintenance.
When gasoline tank is filled (or near full) a strong gasoline odor is noticed at the rear of the vehicle. Odor is stronger on opposite side of filler cap/tube. Dealer was notified and found no problem, attributed it to possibly a loose gas cap.
