2007 Saturn Sky

2 Defect Investigations from the NHTSA

NHTSA Defect Investigations for the 2007 Saturn Sky

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 2007 Saturn Sky, both ongoing and closed, are listed below:

  1. INVESTIGATION: Passenger Sensing System Sensor Mat

    NHTSA Defect Investigation #DP16001

    Component(s): Air Bags: Occupant Classification System - Ocs (Front Passenger)

    Summary: The Office of Defects Investigation (ODI) has received a petition from Mr. Troy Lyman requesting a defect investigation into an alleged defect of the air bag system on 2006-2010 Pontiac Solstice and 2007-2010 Saturn Sky vehicles.The petition letter is attached for review.The petitioner alleges that the Passenger Sensing System (PSS) sensor mat over time will kink, fold and eventually break.The petitioner further alleges that the break in the mat will cause a failure in the circuitry of the sensor mat that may lead to the passenger air bag system being inoperative (suppressed) when the seat is occupied by a passenger that would otherwise require air bag protection.In Attachment B, the petitioner identified 933 complaints received by NHTSA alleging air bag system issues.The identified complaints encompass several General Motors vehicle models in addition to the Pontiac Solstice and Saturn Sky.ODI will evaluate these complaints further to determine if the complaints pertain to the issue cited in the petition.This defect petition has been opened to evaluate the issue and determine whether to grant or deny the petition.


    NHTSA Preliminary Evaluation #PE07037

    Component(s): Power Train:Driveline:Differential Unit

    Summary: ODI evaluated two different alleged defects involving rear drivetrain components during this preliminary evaluation.GM is conducting a recall to address one of the defect conditions and ODI has opened an engineering analysis to continue its investigation of the other alleged defect. On December 19, 2007, GM submitted a defect information report to NHTSA concerning defective rear axle pinion seals in approximately 275,936 model year (MY) 2005-07 Cadillac cts, sts and srx vehicles as well as MY 2006-07 Pontiac solstice and MY 2007 Saturn Sky vehicles (recall 07V-589).on sts and srx vehicles with all wheel drive, the front axle pinion seal also does not meet all of GM's specifications and may experience a fluid leak.GM indicated that the seal supplier made an unauthorized change to the pinion seal material.leaking pinion seals could result in loss of rear differential lubrication which could result in rear wheel lock-up and loss of vehicle control. On December 7, 2007, ODI opened an engineering analysis (EA07-017) to investigate complaints of rear drivetrain component failure (e.g., fractured rear differential carrier housing or rear axle half shafts) while driving in approximately 7,600 MY 2004 through 2006 Cadillac cts-V vehicles.this condition may result in a loss of motive power and vehicle disablement and is not addressed by recall 07V-589.ODI identified 35 complaints (16 to ODI and 19 to GM) and 128 warranty claims potentially related to this condition (see EA07-017 opening resume).these complaints are not included in the failure report summary of this closing resume. The complaints and warranty figures given in this resume are limited to those that (a) are most likely caused by a leaking rear pinion seal; and (B) resulted in an allegation of a rear differential failure while driving.the data do not include all reports of seal leakage.
