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 2000 Chevrolet S-10 Pickup, both ongoing and closed, are listed below:


    NHTSA Preliminary Evaluation #PE02066

    • Status:
    • 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 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.


    NHTSA Engineering Analysis #EA05008

    • Status:
    • Date Opened: April 14, 2005
    • Date Closed: May 19, 2006
    • Recall: No recall issued

    Component(s): Latches/Locks/Linkages:Tailgate:Latch

    Summary: General Motors is conducting a "special policy" program for 903,464 owners of 2000 - 2003 model S/T vehicles through which owners may, at their option, either (1) periodically inspect the tailgate support cables installed in their vehicle and have the cables replaced if the cable coating exhibits any indications of damage or deterioration or (2) request that the tailgate support cables be replaced free of charge. GM will honor all requests by owners who opt for replacement without question regardless of the condition or appearance of the cables. GM has agreed to mail reminder notifications to owners every two years until the tailgate support cables have been replaced or until the vehicle is 12 years old.ODI's investigation indicates that a significant majority of the reported complaints (87%) and injuries (94%) have occurred in MY 2000 - 2003 S/T vehicles.


    NHTSA Defect Investigation #RQ04012

    • Status:
    • Date Opened: November 22, 2004
    • Date Closed: April 14, 2005
    • Recall: No recall issued

    Component(s): Structure:Body:Hatchback/Liftgate:Support Device

    Summary: ODI is upgrading RQ04-012 and opening an ea to investigate the tailgate support cables installed in 1998 - 2004 model year sonoma and S10 model vehicles.General Motors is conducting recall campaign 04V-129 to replace the tailgate support cables originally installed in certain model year 2000-2004 Sierra and Silverado and certain model year 2002-2004 Avalanche and escalade exts (C/K models).General Motors has advised odithat the tailgate support cables installed in the subject vehicles were fabricated using identical or similar sheathing material as the recalled vehicles.however, General Motors has advised ODI that sonoma and S-10 vehicles differ from C/K models in several ways: The vehicle height is lower; the tailgate displacement (drop) when not supported by the cables is smaller and the tailgate comes to rest at a less severe tip angle when not supported by the cables; the tailgate mass is smaller; and the size, payload, and usage characteristcis are less demanding than C/K model vehicles.GM also stated that sonoma and S-10 warranty claim information indicates a lower claim count and a lower claim rate than recalled C/K models.notwithstanding the above information, ODI has received an additional 73 non-injury complaints and 10 injury complaints on the subject vehicles during RQ04-012 (since November 2004 to date), which justifies opening an engineering analysis to further investigate this issue.
