Lot HC1-0619: 2013 Chevrolet Corvette Grand Sport 3LT

The 2013 Chevrolet Corvette Grand Sport is a fantastic choice and generally quite reliable, but there are a few common issues to keep an eye on, especially with this specific car’s Targa roof and automatic transmission:

Heads-Up Display (HUD) The C6 HUD can suffer from a broken mirror housing inside the unit – the display essentially falls out of sight. The 2013 model year is more likely to have the updated HUD, but it’s worth testing during your inspection since it’s listed on this car.

Targa Roof Rattles & Leaks This is perhaps the #1 complaint for C6 Targa models like this one. The Targa roof can develop wind noise and rattles over time. Good news: it’s often fixable with fresh o-rings on the front guide pins, weatherstrip lubrication, and latch adjustments. The FAQ mentions paint chips on the hood – sometimes this indicates the Targa has been removed frequently, which can stress the seals.

Torque Tube Rattle (Automatic Transmission) Since this Grand Sport has the 6L80E automatic, listen for a metallic rattle at idle or low RPMs that goes away when you rev it. This is the “torque tube rattle” – a loose hub nut on the flex plate spindle. Not uncommon on C6 autos, though at just under 16,000 miles this example may not have developed it yet.

Battery Drain C6 Corvettes have over a dozen control modules that can cause parasitic drain. If this will sit for more than a few days at a time, a battery tender is highly recommended.

LS3 Oil Consumption While the LS3 is a robust engine, some do consume oil – check the level regularly, especially if you drive it enthusiastically. The 2013 model year benefited from all C6 production improvements and is considered one of the best years.

Aftermarket Considerations This specific car has a Vararam intake and aftermarket lighting. The intake can affect warranty coverage (if any remains) and may require tuning – worth asking the dealer about.
