Policies
Short version: all sales are final, every kit has a lifetime warranty against defects, and if a pre-order can\'t ship on time you can cancel for a full refund.
Effective October 29, 2026
Every kit is made to order in small batches and tested before it ships, so we don't take returns for a change of mind. Please check fitment before you order; Sparky (the chat in the corner) can help you confirm your kit fits your car.
Every TETROFIT module and harness has a lifetime warranty against defects. If something stops working, we'll help you troubleshoot first, since most problems turn out to be a loose connection or a setting. If it really is defective, we'll email you a prepaid return label. When the part arrives, we test it and send you a replacement, or a refund if you'd rather. The warranty covers the original buyer and normal use; it doesn't cover damage from installation mistakes, accidents, water from a damaged headlight housing, or modifications to the kit.
If your kit arrives damaged or doesn't work out of the box, tell us right away with your order number and a photo. It's covered the same way: a prepaid return label, then a replacement or refund.
Pre-orders are charged when you place them and are final. Each kit shows its expected ship date. If we can't ship by that date, we'll email you before it passes with a new date, and you can choose to cancel for a full refund instead of waiting.
Ask Sparky in the corner of any page, or email support@tetrofit.com, with your order number and what's happening. Keep the original packaging if you can.
