What Is Not Covered

Damage Due to Bedliners

Owners of trucks with a bedliner, whether after-market

covered under the terms of the warranty.

not covered:

overloading, racing, or other competition. Proper

vehicle use is discussed in the owner manual.

• Alteration or modiﬁcation to the vehicle including

the body, chassis, or components after ﬁnal

assembly by GM.

• Coverages do not apply if the odometer has been

disconnected, its reading has been altered, or
