The standard manufacturer warranty that comes with the products lasts for 90 days from the day you receive your product. If you bought an extended warranty, you simply add the length of time you extended your warranty for to the standard 90 day warranty.The warranty covers NON-WEARABLE PARTS and manufacturer defects. Proof of the defect will be required as well as the VIN number of the product you bought for us to file a claim with manufacturers. We are on your side and pride ourselves in negotiating to get parts covered for no cost for our customers.
