These accessories or modifications could even cause malfunction or damage not covered by the vehicle warranty.
Damage to suspension components caused by modifying vehicle height outside of factory settings will not be covered by the vehicle warranty.
Damage to vehicle components resulting from modifications or the installation or use of non-GM certified parts, including control module or software modifications, is not covered under the terms of the vehicle warranty and may affect remaining warranty coverage for affected parts.
