NHTSA complaint #10093933, filed 2004-10, 72,000 miles

“The contact owns a 2000 Gmc Denali. The contact was experiencing difficulty starting the vehicle. The independent mechanic could not duplicate the failures, but provided her with NHTSA campaign id number 05v155000 (fuel system, gasoline:delivery:fuel pump). The manufacturer stated that her VIN was not included in the recall; however, the dealer verified that the failures were caused by the fuel pump. The repair cost was estimated at over $1,000. The vehicle has not been repaired. The current and failure mileages were less than 100,405.”
