2006 CHEVROLET CORVETTE — Complaint #1558161
Open-data reference.
NHTSA Complaint about ENGINE filed April 15, 2019
NHTSA complaint #1558161 (ODI reference 11196516) concerns a 2006 CHEVROLET CORVETTE and was filed on April 15, 2019. The owner reports the failure occurred on June 21, 2013. The vehicle had 20,000 miles on the odometer at the time of the incident. The report was geocoded to California based on the filer's self-reported location. The affected component is categorized as engine, one of NHTSA's standardized taxonomy codes used to group defect patterns across make, model, and year.
The filer flagged the following severity indicators: crash: no, fire: no, injuries: 0, fatalities: 0. No crash, fire, or fatality was associated with this report, which places it in the early-warning stream rather than the priority-review stream. Because a VIN was supplied, this complaint is tied to a specific vehicle and not just a model-year cohort.
Individual complaints are consumer-submitted and unverified by NHTSA engineers — the agency's role at this stage is to collect, index, and make them searchable. What matters for federal action is the pattern: when many owners of the same CHEVROLET CORVETTE cohort independently describe similar engine failures, defect investigators have grounds to open a PE and request manufacturer data. Related filings for the same vehicle and component appear below, and the detail page for the full 2006 CHEVROLET CORVETTE shows the complete component-level complaint distribution alongside any active investigations or recalls.
Complaint Description
LS7 ENGINE MAKES LOUD "TICKING" SOUND AT IDLE TO ~ 2,000 RPM CAUSED BY DEFECTIVE CYLINDER HEADS WHICH WERE IMPROPERLY MACHINED BY GM'S SUBCONTRACTOR. LOCAL CHEVROLET DEALERS SAID THE NOISE IS "NORMAL"... BUT WHEN HEADS OPENED AND VALVE AND VALVE GUIDES MEASURED, EXCESSIVE VALVE AND VALVE GUIDE WEAR DOCUMENTED. LOCAL GM DEALER & $4,350 GM PROTECTION PLAN (EXTENDED WARRANTY THAT I HAD TO BUY TO COVER THIS $5,000 REPAIR) REFUSED TO REPAIR SO I HAD TO DRIVE IT 5 HOURS TO ANOTHER GM DEALER TO GET IT REPAIRED UNDER MY GMPP EXTENDED WARRANTY. MANY OTHER 2006 TO 2015 CORVETTE OWNERS HAVE EXPERIENCED THIS SAME EXCESSIVE VALVE WEAR INCLUDING SOME OWNERS VALVES BREAKING AND DESTROYING THEIR $16,000 LS7 MOTORS WHILE SPEWING OIL AND METAL EVERYWHERE. THIS ALSO RESULTED IN A FEAR OF DRIVING THIS CAR, A SIGNIFICANT "DIMINISHMENT OF VALUE" OF THIS VEHICLE, AND COMPLICATED ITS RESALE (BUYERS HAD HEARD ABOUT THESE CATASTROPHIC LS7 MOTOR FAILURES.
