    Several years ago I video taped A world class Corvette tech at one of our gatherings. He was addressing the issue directly. At that time, it was in reference to the C5, but I believe it will pertain to the C6 as well.

    The 2005 C6 has the exact same column lock as the 2004 C5. WITH all of the same issues. A good battery that meets or exceeds the factory rating is the best way to avoid this problem.

    Both replies are great information.

    I will add though to have ANY battery properly load tested with a carbon pile load tester, new or old.

    Extremely important, especially when dealing with a column lock issue.
