Kestrel Take

The last of the C6, a car people buy for the 60th Anniversary trim and the send-off specials, and the public record for it is dominated by one complaint: 48 of 82 filings are fuel leaking from the top of the tank. NHTSA lists no recall campaigns for this year, so that repair comes out of your pocket. The other thing to settle before you fall in love is which engine is in it — the 7.0-litre in the Z06 and 427 convertible has a valve-guide reputation the base 6.2 does not share, and owners in this file describe exactly that failure. Check the badge, then pay for a leak-down test on the big-engine cars. Neither of those is a reason to walk; both are reasons to negotiate.

What we checked

Reconciled against public records, 2026-09-25

NHTSA holds 82 owner complaints for the 2013 Chevrolet Corvette, and no recall campaigns.

A big number here usually means a lot of these were sold, not that it is a bad vehicle — popular models collect more complaints for the same rate of trouble. So the total on its own says little. What is worth reading is the shape of it. 59% of them are about one thing — the fuel system. That much concentration is a genuine pattern rather than background noise, and it is the first thing to check on any example you look at.

Counts come from the NHTSA complaint and recall database — free, public, and worth checking yourself.

Known Issues for the 2013 Chevrolet Corvette

Ranked by wallet impact. These are documented, recurring problems — not freak accidents. How we decide that.

Fuel leak at the tank module flange — the smell arrives before any warning lightHigh — wallet impact

Forty-eight of 82 complaints, and the descriptions barely vary: strong petrol smell in the garage after filling, strongest above half a tank, coming from the driver's-side forward wheel well, with nothing on the dash and often nothing visible on the floor. One owner had the car sitting at a dealership for months waiting on a crossover fuel line. The seal at the primary tank module flange is the usual failure point. Fill it, drive it, park it in an enclosed space and come back in ten minutes — this is the single most valuable ten minutes of the inspection.

Repair cost (estimate): $700–$2,400 per tank module including labour

Airbag light tied to the yellow connector under the driver's seatMedium

Ten complaints, and owners located the cause themselves: a yellow connector beneath the driver's seat that the easy-entry seat travel keeps disturbing, so the airbag light comes on at startup and stays, or flickers for years without a dealer ever catching it lit. One owner in this cluster could not buy a passenger presence module at all — back-ordered repeatedly — so a car with the passenger airbag refusing to arm may be a long wait for parts. Run the seat through its full travel, watch the light through a cold start, and check the passenger side arms with someone sitting in it.

Repair cost (estimate): $150–$1,100 — cleaning and securing the connector at the low end, a restraint module at the high end

Valve-guide wear on the 7.0-litre cars can drop a valve and destroy the engineHigh — wallet impact

Eight engine complaints, mixed in content — one is really a fuel pump story — but several describe the failure this engine family is known for: a valve guide wearing out of specification, the valve head breaking off and going through the piston, and a total engine loss with no warning. One owner lost his at about 18,500 miles on a mountain road. The big-bore 7.0 in the Z06 and 427 convertible carries this reputation; the 6.2 in a base or Grand Sport does not. Find out which engine you are buying, then spend the money on a leak-down test and an oil analysis.

Repair cost (estimate): $3,500–$6,000 for a cylinder head rebuild with new guides; $12,000–$20,000 for a replacement engine — around 53% of what this car is typically worth

Driveline rattle from the torque tube at a standstillMedium

Owners of this generation describe a loose, rolling rattle from under the centre of the car when it is stopped in gear, which quietens in neutral or with the clutch down — the bearings inside the torque tube between the engine and the rear transaxle. It is not a cluster of its own in this year's file, so we are calling it from owner reports rather than the public record. Listen for it at a stoplight with the windows down. It is not dangerous, but the repair means dropping the driveline, so finding it beforehand is worth a few thousand dollars of negotiation.

Repair cost (estimate): $1,200–$2,800
