Is GM Genuine Parts on Sale? November 2026

Questions and answers

What makes GM Genuine Parts different from aftermarket brands?

They are engineered and validated by General Motors for its own vehicles, so connectors, resistance values and fit match the original part. Aftermarket equivalents often cover many models with one design and can need adapter harnesses or splicing.

How do I confirm a part fits my vehicle?

Match the part number against your VIN through a GM dealer or the GM parts catalog before ordering. Wiring harnesses and oxygen sensors vary by engine, emissions package and body style, so the same name can cover several different parts.

Do GM Genuine Parts carry a warranty?

GM replacement parts sold through dealers typically carry the GM limited parts warranty, which covers defects in materials and workmanship for a set period. Terms can differ for counter sales versus dealer-installed work, so confirm with the seller.

Can I return a GM Genuine Part if it does not fit?

Return policies come from the individual seller, not from GM. Electrical parts such as sensors and harnesses are often excluded once installed or once the packaging is opened, so check the seller's terms before you order.

Are these parts the same as the ones on the car when it was built?

In most cases yes. GM Genuine Parts are the service replacements for the original components, though GM sometimes supersedes a part number with a revised design. The listing's part number tells you which version you are getting.
