Cause The cause of the condition may be that the carbon fiber hood and engine cover use a different impregnated carbon fiber resin, which is more heat resistant. The different resin may cause a color shift; and the lighting source and direction of view will sometimes highlight this color shift. Correction There is no problem with the paint application on these carbon fiber parts, and NO repair attempts should be made to change the color of the parts. Version 2 Modified Released February 28, 2019 Revised August 24, 2022 – Added 2020–2023 Corvette Model equipped with ZZ3, updated the Involved Region or Country section and Condition.
