NHTSA Defect Investigations for the 2007 Chevrolet Corvette

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 Chevrolet Corvette, both ongoing and closed, are listed below:

  1. Simultaneous Loss of Low-Beam Headlights NHTSA Engineering Analysis #EA13007

    Component(s): Exterior Lighting
    Exterior Lighting:Headlights

    Summary: On May 14, 2014, General Motors (GM) submitted a Part 573 defect information report initiating NHTSA Safety Recall 14V-251 to remedy the subject vehicles.GM will remedy a defect condition in the underhood bussed electrical center (UBEC) by modifying the vehicle's electrical harnessing.GM also announced a customer satisfaction bulletin to address this issue on model year (MY) 2008-2013 Chevrolet Corvettes.Both programs will be conducted free of charge.According to GM, when the engine heats up and cools down (from normal use), the plastic material in the UBEC housing expands at a different rate than an electrical conductor routed within it.The difference in expansion rates results in bending of the conductor, a control circuit for the low beam headlights.After multiple thermal cycles, often taking several years of use, the conductor fractures resulting in an open circuit.When this occurs the low-beam headlights will not illuminate.After the engine is turned off and the UBEC cools, the conductor may temporarily reconnect and restore low-beam function, although subsequent failures will occur.This condition does not affect high-beam headlights, marker lamps, turn signals or fog lamps.Simultaneous loss of low-beam headlights could reduce the driver's visibility, increasing the risk of a crash. The ODI report counts noted above, involving the loss of low beam headlights, represents those received at the time of GM's recall filing; however NHTSA has since received additional complaints.GM submitted similar complaints in response to the agency's information request.Among the complaints reported to NHTSA, five alleged minor crashes in which the vehicle ran off the road or into roadside objects due to the sudden loss of headlights.Two of these complaints alleged minor injuries and three alleged property damage.Several other reports to NHTSA alleged close calls due to the loss of lighting.GM states that it has received no reports of crashes, injuries or fatalities as a result of this condition. GM's recall action appears to adequately address the safety risks in the subject vehicles of concern to ODI.Accordingly, the investigation is closed.In addition to recalling the subject vehicles, GM is covering MY 2008-2013 Corvettes, which contain essentially the same UBEC, under a customer satisfaction campaign.ODI notes that these vehicles exhibit a lower likelihood of failure due to their comparatively shorter service life.

  2. Loss of Low Beam Headlights NHTSA Preliminary Evaluation #PE13013

    • Status:
      CLOSED
    • Date Opened: May 06, 2013
    • Date Closed: August 26, 2013
    • Recall: no recall issued

    Component(s): Exterior Lighting
    Exterior Lighting:Headlights

    Summary: The Office of Defects Investigation (ODI) opened this investigation based on 30 reports from consumers alleging that, after driving for a short time (5 to 30 minutes), both low beam headlights stopped working simultaneously and without warning. The low beam headlights remained inoperative for the remainder of the drive cycle, however no other lighting is affected.General Motors (GM) provided information in response to ODI's information request letter explaining that the loss of headlights is caused by a fractured low beam circuit wire in the underhood bussed electrical center (UBEC), a device that is similar to a fuse box. The UBEC is located in a high heat area near the engine, and the low beam circuit wire routing within the UBEC makes it susceptible to cyclical stress caused by thermal expansion.The investigation covers model years 2005-2007 Corvettes however ODI also has received four VOQs alleging the same condition in model year 2008 Corvettes. ODI is upgrading the investigation to an Engineering Analysis to further examine the consequences, frequency and scope of this problem. The ODI reports cited above can be reviewed at www-odi.nhtsa.dot.gov/owners/SearchNHTSAID under the following identification (ODI) numbers.For MY 2005-2007: 10400308, 10415603, 10415867, 10416531, 10421639, 10424391, 10424543, 10445971, 10451733, 10454919, 10460674, 10460750, 10463546, 10466342, 10466857, 10468128, 10469057, 10470616, 10471595, 10474350, 10474368, 10475257, 10486597, 10491670, 10496592, 10496788, 10498100, 10502059, 10505606, 10508507, 10510052, 10511467, 10511517, 10511576, 10511696, 10511699, 10511789, 10511837, 10511994, 10512072, 10512093, 10512154, 10512292, 10512341, 10513422, 10514802, 10514978, 10515162, 10515311, 10515821, 10519426, 10519879, 10520155, 10521036, 10521585, 10522260, 10523064, 10523190, 10525646, 10531602, 10531631, 10532439, 10533227, 10533251, 10533339For MY 2008: 10512856, 10514576, 10523059, 10532221
