While Chevrolet's Corvette is highly regarded for its ability to blow the doors off of sports cars orbiting far higher price brackets, it now appears that the General Motors' C6 engineers are also fans of Parliament Funkadelic. How else to explain the recently surfaced TSB indicating that Corvettes are prone to following George Clinton's anthemic directive: Give Up the Funk (Tear the Roof Off This Sucka) ?

According to first-hand experience of the members of CorvetteForum.com and a referenced General Motors TSB, the Chevy flagship is experiencing roof delamination, which manifests itself as the outer layer of painted roof models peeling back and tearing off, creating something approaching an unintentional C6 targa.

The TSB covers 2005-2006 model year Vettes, and blames high temperature and humidity along with exposure to "stresses" as the leading causes of roof adhesive failure. High speed doesn't appear to be a prerequisite to the panel's separation, so C6 owners would do well to inspect their rides regardless of the way they light up their tires.

STEPS 3 AND 23 IN THE SERVICE PROCEDURE HAVE BEEN REVISED. PLEASE REVIEW THE REVISED PROCEDURE IMMEDIATELY. DISCARD ALL COPIES OF BULLETIN 05112 ISSUED FEBRUARY 2006.
--------------------------------------------------------------------------------

THIS PROGRAM IS IN EFFECT UNTIL MARCH 31, 2007.

Condition
On certain 2005-2006 Chevrolet Corvette vehicles, the painted roof panel may separate from its frame in some areas if it is exposed to stresses along with high temperature and humidity. The occupants of the vehicle may notice one or more of these symptoms: a snapping noise when driving over bumps, wind noise, poor roof panel fit, roof panel movement/bounce when a door or hatch is closed, or a water leak in the headliner.

Correction
Dealers are to apply adhesive foam to ensure proper adhesion, or in a small number of vehicles, replace the roof panel.

Involved are certain 2005-2006 Chevrolet Corvette vehicles with a painted roof, and built within these VIN breakpoints:

The Campaign Initiation Detail Report may contain customer names and addresses obtained from Motor Vehicle Registration Records. The use of such motor vehicle registration data for any purpose other than follow-up necessary to complete this program is a violation of law in several states/provinces/countries.
