Return Policy

All Sales Are Final

All purchases from Onyx Auto Parts are final sale. We do not accept returns or issue refunds except in cases where an item is defective and covered under our warranty policy.

Please verify compatibility before purchasing. If you are unsure whether a part fits your vehicle, contact us before buying.

Defective Items

If you receive an item that is defective or was incorrectly described, you may be eligible for a replacement or refund under our Warranty Policy. To qualify:

• The defect must be reported within the warranty period
• The item must not have been damaged after purchase
