NHTSA Defect Investigations for the 2001 GMC Sonoma

The Office of Defects Investigations (ODI) is an office within the NHTSA which investigates serious safety problems in the design, construction or performance of vehicles. The NHTSA is authorized to order manufacturers to recall and repair vehicles, if the ODI finds a safety issue. NHTSA investigations for the 2001 GMC Sonoma, both ongoing and closed, are listed below:

  1. ENGINE STALL DUE TO FUEL STARVATION NHTSA Preliminary Evaluation #PE02066

    • Status:
      CLOSED
    • Date Opened: September 06, 2002
    • Date Closed: November 03, 2003
    • Recall: no recall issued

    Component(s): Fuel System, Gasoline
    Fuel System, Gasoline:Delivery:Fuel Pump
    Fuel System, Other
    Fuel System, Other:Delivery:Fuel Pump

    Summary: ODI opened PE02-066 to evaluate the scope and consequence of engine power-loss due to fuel starvation induced by in-tank modular fuel pump strainer restriction.the subject pumps use an external 'sockż strainer to filter fuel flowing to the pump inlet.this filter can sometimes become clogged, resulting in a reduced flow of fuel to the engine.GM has subsequently modified the strainers to reduce this restriction.analysis of the ODI complaint database shows that despite these restrictions, the subject vehicles stall at a rate that is comparable to those of many peer vehicles.additionally, none of the relevant warranty repair rates exceed 1% at 36 months of exposure.one related crash involves a stalled vehicle that was rear-ended on the roadway, while the remainder involved minor collisions or scrapes.the sole injury consisted of bruising from a low speed frontal crash. Given these circumstances, further expenditure of Agency resources is not justified in this matter.the preliminary evaluation is therefore closed.the closing of this investigation does not constitute a finding by NHTSA that no safety-related defect exists.the Agency will take further action in the future if warranted.
