Warranty on Genuine GM Parts

What the factory parts warranty covers when you buy over the counter.

The Basics

Genuine GM parts purchased over the counter carry a parts warranty from GM. Terms vary by part category.

Emissions Parts

Catalytic converters and certain emissions components have separate federal coverage periods that may be longer.

What Is Not Covered

Damage from improper installation, and wear items consumed in normal use.

Keep the Receipt

It is the single thing that makes any warranty conversation short.

If you are not sure which version fits your build, send us the VIN and we will confirm before anything ships. Shop our Chevrolet OEM parts catalog or search for GM parts.
