Safety record from NHTSA: recalls, owner complaints, investigations and service bulletins.
These records cover every 2006 Chevrolet Corvette Z06. To see whether one car still needs a recall repair, decode its VIN or check it with NHTSA.
1 recall names the 2006 Chevrolet Corvette Z06. Newest first.
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…
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.
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.
The front lights of the car one of them isn't working. I believe this isn't the first complain about this kind of car. It IS dangerous to be driving on the road. I have to continue to put my high beams on for them to work. At times both the lights are on and with time driving it will turn one of them off. It's dangerous because the visibility on the road for me and other drivers.
Valve rattle, not driving vehicle to keep from dropping valve......costs $4K for repair to heads....31000 miles... If I drive it and drop valve, will cost $18K to replace engine assembly.....long term value of vehicle decreases with non-matching numbers vehicle. One helluva way to treat customers that spend $85K on a vehicle.
I never received any notice from gm, but I brought it to the dealer's attention while I was in for a recall repair in 2008. I told the tech that my traction control, active stability control, wasn't working properly. When I received the car back the tech said the traction control IS fixed and working fine. I didn't see how he could have said that when the car never left the shop. I realize now that he was aware of something that I wasn't. The traction wasn't fixed, but I felt that I can't bring it back due to incompetence. I went to forums and found plenty of complaints from others. Then I noticed that 2005-2006 corvettes with the rpon37 steering column built in 2005 were recalled for this. Nhtsa campaign number was 10v172000 and gm's campaign # was n100118. I called gm they said I am mistaken my car IS not affected which IS [xxx]. I then found from the internet that part #19179794, clip, was used to fix the issue. I then ordered one of these and followed the instructions to repair it and found this clip was installed, but improperly hence the reason it wasn't fixed by the tech, but he was under the impression it was solved. I then replaced the clip properly and now it's ok. Gm was very difficult and dismissive during the entire ordeal. Looking on your web site it specifically states that my vin # does in fact fall into the specs of your recall. I am going to enclose a photo of the bent, improperly, installed clip and a proper picture of the clip. Also the harness that needs the clip to show that the bent prong IS needed to repair the harness. parts of this document have been redacted to protect personally identifiable information pursuant to the freedom of information act (foia), 5 u.s.c. 552(B)(6).
I recently had my valves tested by a local shop since ive heard from other owners that the LS7 valves drop at any given time. I had two valves out of specs and have to get it fixed in order to save engine from future damage. My car currently has 52,241 miles.
I had a friend who had an engine failure on this same engine due to a failed exhaust valve. the valve guides were extremely worn on his car causing the valve failure. due to his failure and many others like it, I removed my heads and inspected. sure enough, they were significantly beyond general motors published tolerances and required machining to repair. this was at significant cost to me and out of pocket. gm knows of this issue and refuses to participate in repair costs for cars out of warranty even though it's a design flaw and safety concern. if and when the valve catastrophically fails, the engine will have a complete shut down, large amounts of smoke out the exhaust clouding the other drivers vision, and has the possibility of leaving oil slicks on the road surface. *tr
Valve guides out of wear with possible failure including valve to drop inside combustion chamber
I was interning the interstate 15 in california and was picking up speed to inter the hwy and my corvette Z06 starting making a knocking sound and lost power and I turned it off and had it looked at my a very well know automotive shop who specializes in gm vehicles. They told me it drop an exhaust valve.
I was concerned about a noise that I was hearing in my 2006 Z06 that IS unlike any other noise I have heard while currently owning my three other gm vehicles. I decided to bring it to a well know corvette speciality shop near me. The told me about the valve guide issue that has been linked to the LS7 heads. I immediately told him to take the heads off the car and check them. I had 4 exhaust valves that were way out of gm specs. I had the heads re-machined properly and installed new intake and exhaust valve guides, valve springs and seals.
Airbag disabled light comes on under normal driving conditions. Sometimes goes out after restart.
Driving on the freeway at approx. 65 mph. , the steering wheel on my car " took control of itself and jerked to the left: on the dash pod it stated " service active handling system" . I pulled the car over as soon as I could do so safely and shut the car off. After restarting it the warning went away and the steering returned to normal.
Vehicle has a constant airbag indicator illuminated. Airbags have never been deployed.
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).
Cruising at 50 mph on feeder ramp and dic showed engine power reduced for 2 seconds then boom! *tr
I bought this corvette Z06 used from a private party. The engine had a catastrophic failure due to a known issue with the valve guides and valves in the LS7 motor from the factory. I was driving home from work when the motor failed. I was lucky to be only a mile from home when it failed and I was able to coast into my garage. 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. I have tried several times to get chevy to help me with this motor, but they will not help at all. They know about the problem, but will not lift a finger to help anyone. *tr
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.
Date of heads pulled: 7/5/12 head type: gm LS7 year: 2006 miles: 16,000 track time: none tune: stock I had my cylinder heads removed because I was paranoid after reading online about many other owners having issues with their valve guides being out of spec. 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. I paid out of my own pocket to have these heads redone.

My son was driving and just completed a turn when he applied the accelerator and the engine stopped abruptly. there was a cloud of smoke and then a small fire underneath the car from the oil that came out from a baseball size hole in the side of the block below the number 8 cylinder. upon further investigation, a valve in the number 8 cylinder snapped below the valve guide dropping the head of the valve onto the piston which caused the failure. I have the engine available for inspection. *tr
Hello, I am reporting on my 2006 c6z06 corvette that recently had the valve-to-guide clearances checked on my engine and my measurements are beyond the serviceable specifications on 8 out of 16 valves, both intake and exhaust. I consider this a safety hazard due to the fact that if the vehicle IS driven and engine seizes, loss of control may occur. I also have what appears to be a leak on the fuel module/sending unit, specifically on the top plastic elbow connector. I have strong gasoline odor in the cabin of the car and visible gasoline from the underside of the car near the fuel tank. *tr
The cylinder heads at 69K miles were checked due to excessive valve train noise and the valve guides and one intake valve were found to have clearance more than double the service tolerance. *tr
TL* the contact owns a 2006 chevrolet corvette Z06. The contact received a recall notification for nhtsa campaign number: 14v251000 (electrical system, exterior lighting). The dealer could not repair the vehicle for two months because the parts were not available. The manufacturer was notified. The contact had not experienced a failure.
This car was converted to a race car. the accident occurred at road atlanta before turn 10A. the active handling apparently caused the right brakes to engage causing a clockwise snap spin that resulted in hitting the inside concrete retaining wall. A youtube video IS available at: https://www.youtube.com/watch?v=--x0tr5g_u8&feature=youtu.be ( the accident obviously occurs at the end of the video.) *tr
Low beam headlights went out without notice and would not come on. Was driving at the time the went out. I made it home using high beams. Low beams came back on the next morning but after my testing the would go out after apx 15 minutes and would not come back on for hours. *tr
While driving in a straight line at approximately 65 mph, the traction control system strongly applied the left front brake. The application of brake was sudden and very strong, nearly causing a loss of control. *tr
NHTSA’s Office of Defects Investigation opened these reviews into vehicles including this one.
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.

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 http://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
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.
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.
