what are common problems with the 2013 corvette grand sport?

Question

Accepted Answer

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.
