2006 Chevrolet Corvette Z06 problems

What is wrong

General motors is recalling certain model year 2005 through 2007 corvette vehicles equipped with a removable roof and model year 2006 and 2007 corvette z06 vehicles. The adhesive between the roof panel and the frame may separate. If there is a partial separation, the driver may notice one or more symptoms, such as a snapping noise when driving over bumps, wind noise, poor roof panel fit, roof panel movement/bounce when a door or hatch is closed, or a water leak in the headliner.

Risk

If there is a complete separation, the roof panel may detach from the vehicle. If this were to occur while the vehicle was being driven, it could strike a following vehicle and cause injury and/or property damage.

Remedy

Dealers will install a new design roof panel free of charge. The safety recall is expected to begin during april 2010. Owners may contact chevrolet at 1‑800‑630‑2438 or at www.gmownercenter.com.

Recall number 09V491000 · Recall details

On May 14, 2014, General Motors (GM) submitted a Part 573 defect information report initiating the federal safety agency 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 the federal safety agency has since received additional complaints.GM submitted similar complaints in response to the agency's information request.Among the complaints reported to the federal safety agency, 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 the federal safety agency 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.

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.

PE13013

On April 26, 2010, at the federal safety agency's request following this investigation, General Motors submitted a Defect Information Report to the federal safety agency to correct a defect associated with the Vehicle Stability Control (VSC) system in approximately 40,000 Model Year (MY) 2005 and 2006 Chevrolet Corvette vehicles (the federal safety agency Recall No. 10V‑172).According to the report, these vehicles may have a problem with the Steering Wheel Position Sensor (SWPS) connector created by a fretting condition in the connector (small movement of the pins back and forth creating a residue build up) which could change the electrical resistance and corrupt the information signal to the VSC computer.The VSC system uses the information from the SWPS to calculate the driver's intended vehicle direction; this information is cross referenced to sensors that tell the system which direction the vehicle is actually going and the system will, if it determines a variance indicating the vehicle is in a over-steer or under-steer condition, reduce throttle control and apply braking to make a correction in vehicle direction towards what the system believes is the driver's intended path.GM dealers will inspect the SWPS connector of recalled vehicles and, if necessary, install a terminal position assurance clip to the connector.GM has advised the federal safety agency that its position is that the inappropriate activations of the VSC system do not present an unreasonable risk to safety because GM believes that the activations are low in occurrence, a rare set of conditions would need to be present, the driver has the ability to maintain direction control if the alleged condition were to occur, and that there are no reports of injuries.the federal safety agency does not agree.Based on interviews with complainants and testing performed at the federal safety agency Vehicle Research and Testing Center in East Liberty, Ohio, ODI believes that the majority of the unwarranted activations of the VSC system occur when turning, in such scenarios as travelling highway entrance or exit ramps or in street traffic conditions.Complainants report the effect produced by the malfunction of the VSC system is sudden unexpected braking and in some cases a sudden unexpected change in vehicle direction which some complainants indicate was sufficient to cause a movement into an adjoining lane of traffic or in some cases into curbing or stationary objects.During the VSC event the brake lights of the Corvette are not illuminated, depriving trailing traffic from indication that braking is occurring and some complainants indicate the braking effect can be severe and last up to 10 seconds in length.Based on available information ODI counts four crashes due to a malfunction of the VSC system; GM is counting one crash due to the problem.In these circumstances the federal safety agency believes the defect presents an unreasonable risk to motor vehicle safety, and so advised GM when requesting this recall.This investigation is closed based on GM's recall.

On september 17, 2008, odi opened preliminary evaluation pe08-056 to investigate allegations of inappropriate activation of the electronic stability control (ESC) system in model year (my) 2005 and 2006 chevrolet corvette vehicles.some reports received by odi and some reports to general motors (gm) contained in gm's response to pe08-056 allege that the ESC system malfunctioned causing a sudden and inappropriate braking action without illumination of the brake lights and causing the vehicle to swerve left or right unexpectedly. Gm issued a technical service bulletin in january 2006, later revised in october 2007 (bulletin no. 06-02-35-002b) concerning ESC problems in my 2005 and 2006 chevrolet corvette vehicles with the telescoping steering wheel option.the bulletin was intended to correct a fretting corrosion problem with the steering wheel position sensor connector c202. An engineering analysis has been opened (ea09-002) to continue to asses the scope, frequency, and safety-related consequences of the alleged defect.
