I WAS DRIVING DOWN A BUSY STREET AT 35 MPH IN HEAVY TRAFFIC AND HEARD A METALLIC SOUND. THE ENGINE LOCKED UP AND THE REAR END SKIDDED TILL I PUT IN THE CLUTCH AND COASTED TO A PARKING LOT. I WAS AWARE OF THE VALVE PROBLEMS SO I TOOK THE HEAD OFF THE ENGINE AND SURE ENOUGH DROPPED A VALVE TAKING OUT THE PISTON AND BREAKING THE BLOCK. I TOOK THE CAR TO KOOL CHEVY AND WAS TOLD IN WOULD COST 22,000 DOLLARS TO FIX IT. KOOL TOLD ME GM WOULD NOT COVER ANY OF IT BECAUSE THE CAR WAS OUT OF WARRANTY AT 59,000 MILE ON THE CAR. I COULD NOT AFFORD TO FIX THE CAR SO I SOLD THE CAR AS IS LOSING MORE THAN HALF WHAT THE CAR WAS WORTH. I AM STILL SICK ABOUT THIS A YEAR LATER AS I WILL NEVER BE ABLE TO HAVE ANOTHER CAR LIKE THIS. I FEEL LIKE GM SHOULD HAVE WORKED WITH ME AS THIS WAS A KNOWN PROBLEM WITH THE LS7 ENGINE. IF THIS WOULD HAVE HAPPENED AT HIGHWAY SPEEDS IT WOULD HAVE BEEN A LOT WORSE THAN IT WAS. LOST POWER STEERING, POWER BRAKES, AND SKIDDED WHEN THE ENGINE LOCKED UP.

RARELY, DURING LOW SPEEDS (UNDER 15 MPH), WHILE DRIVING STRAIGHT, THE LEFT REAR WHEEL WILL LOCK UP, INDUCING A HARSH LEFT TURN, UNSTABLE MANEUVERING, AND CAUSING THE MOTOR TO ATTEMPT TO STALL. STEERING IS EXTREMELY UNSTABLE AND VIOLENT AND OPERATOR HAS TO FIGHT AGAINST THE CAR WANTING TO TURN LEFT BY APPLYING EXTREME RIGHT TO THE STEERING WHEEL. THE ONLY REMEDY IS TO ENGAGE AND DISENGAGE THE CLUTCH SEVERAL TIMES UNTIL THE LEFT REAR WHEEL UNLOCKS. SYMPTOMS HAVE NOT OCCURRED DURING NORMAL TRAFFIC SPEEDS (ABOVE 15 MPH). AUTO HANDLING/TRACTION CONTROL AND ABS LIGHTS ARE ACTIVATED DURING THIS EVENT. VEHICLE IS IN FACTORY CONDITION. ONLY EXCEPTION IS ALTERNATE BRAND OF TIRE (NITTO INVOS) - BUT MAINTAINING FACTORY SPECIFICATIONS (FRONT: 275/35ZR18; REAR: 325/30ZR19). HAVE NOT REPORTED TO MANUFACTURER YET (IT IS TOO RANDOM AND RARE TO REPRODUCE ON A PREDICTABLE OCCURRENCE). ENVIRONMENTAL CONDITIONS: NORMAL (SUNNY, DRY PAVED SURFACE).

THE EXHAUST VALVE DROPPED AND DESTROYED THE #1 PISTON ALONG WITH THAT CYLINDER, AND THE ENGINE BLOCK. NOTHING IN THE MOTOR IS SALVAGEABLE AS IT BENT OR SENT METAL SHARDS INTO EVERY PART OF THE MOTOR.

MANUFACTURING DEFECTED IN THE LS7 MOTOR. UPON FURTHER INVESTIGATION I HAD MY 2006 CORVETTE Z06 INSPECTED FOR A LOUD AUDIBLE TICK IN THE MOTOR. THE SOURCE OF THIS NOISE WAS FROM THE IN-BALANCE FROM THE #3 AND #4 INTAKE VALVES ON THE ENGINES HEADS. THERE IS PREMATURE WEAR ON BOTH VALVE GUIDES CAUSING INTERNAL FAILURE TO THE MOTOR. UNDER POWER DEMAND THE IN-BALANCE WILL CAUSE THE TITANIUM ROD TO STRIKE THE SIDES OF THE VALVE SEAT CAUSING THE HEAD OF THE VALVE TO CRACK AND FALL INTO THE CYLINDER. ONCE THIS OCCURS INSTANT CATASTROPHIC FAILURE OF THE MOTOR HAPPENS RESULTING IN WHITE BELLOWING SMOKE FROM THE EXHAUST, OIL SPILLAGE, AND ENGINE LOCK RESULTING IN THE VEHICLE SKIDDING OFF THE ROAD OR LOOSING CONTROL. FORTUNATELY FOR ME I CAUGHT THIS IN TIME BEFORE HAVING A CATASTROPHIC FAILURE. BOTH LS7 HEADS ARE BEING REPAIRED AND MACHINED TO MEET INDUSTRY STANDARDS. THIS PROBLEM MUST BE ADDRESSED TO ALL LS7 Z06 OWNERS AS IT COULD AND HAS CAUSED SEVERAL CRASHES AND POSSIBLE DEATHS. ONCE REPAIRS TO THE LS7 HEADS ARE MADE THE VEHICLE CAN BE RETURNED TO SERVICE. *TR

2006 Z06 CORVETTE ENGINE WAS MAKING AN UNUSUAL NOISE. AFTER DOING SOME RESEARCH AND THE FINDING, IT WAS DETERMINED THAT THE VALVETRAIN ON THE ENGINE MAY BE PENDING FAILURE. THE HEADS WERE REMOVED AND VALVE TRAIN TOLERANCE CHECKED TO BE FOUND WAY OUT OF SERVICEABLE LIMITS. THUS REQUIRING REPAIR. THIS WAS CONSIDERED EXCESSIVE WEAR FOR SUCH A LOW MILEAGE VEHICLE THAT WAS PENDING CATASTROPHIC ENGINE FAILURE IF THE REPAIRS TO THE HEADS WAS NOT PERFORMED. IN DOING ADDITIONAL RESEARCH, THIS APPEARS TO BE QUITE COMMON FOR THE Z06'S 7.0L LS7 ENGINE. LUCKILY MY ENGINE DID NOT HAVE A CATASTROPHIC FAILURE BECAUSE I TOOK PREVENTATIVE MEASURES AT MY OWN COST, BUT THIS DESIGN SHOULD BE CONSIDERED A FAILURE AND RECALLED. I WAS NOT GOING TO RISK A CATASTROPHIC ENGINE FAILURE POSSIBLY ON THE HIGHWAY AND PUT MYSELF AND OTHERS AT RISK. PLEASE INVESTIGATE.

MY CYLINDER HEADS HAD VALVE GUIDES THAT WERE WAY OUT OF SPEC AND THE CAR ONLY HAD 16,000 MILES ON IT AND WAS NEVER TRACKED OR ABUSED. THESE WERE ON THE VERGE OF HAVING THE VALVE BREAK OFF AND SEIZE THE MOTOR WHICH COULD HAVE RESULTED IN SERIOUS INJURY TO MYSELF AND OTHERS AROUND ME WHILE DRIVING.

EA13007 · Simultaneous Loss Of Low-Beam Headlights

Opened Aug 23, 2013 · Closed Jun 24, 2014

Status: closed (inferred from source dates) · Exterior Lighting; Exterior Lighting:headlights

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.

Status: closed (inferred from source dates) · Exterior Lighting; Exterior Lighting:headlights

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.

EA09002 · Electronic Stability Control

Opened Jan 14, 2009 · Closed May 11, 2010

Status: closed (inferred from source dates) · Electronic Stability Control

On April 26, 2010, at NHTSA's request following this investigation, General Motors submitted a Defect Information Report to NHTSA 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 (NHTSA 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 NHTSA 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.NHTSA does not agree.Based on interviews with complainants and testing performed at the NHTSA 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 NHTSA 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.
