Also, for a lot of items, Amazon isn't an "authorized retailer," so you may also have a manufacturer that won't warranty an item for that reason. People have run into that issue with hand tool warranties. Amazon even admits this in the fine print:

Manufacturer's warranties may not apply in all cases, depending on factors like the use of the product, where the product was purchased, or who you purchased the product from. Please review the warranty carefully, and contact the manufacturer if you have any questions.
If the manufacturer wants you to go through the retailer you bought it from for warranty, you may be out of luck. But Amazon now has this wording about automotive warranties:
Quote:
Automotive Items
If you have purchased an automotive item shipped from and sold by Amazon.com that is defective and is covered by a manufacturer’s published warranty, Amazon will either replace the item or refund the cost of the item for the life of the published warranty.
This is the best answer to OP question.
If part(s) is defective when install during the return period then it is easy to return to Amazon for exchange or refund. If part(s) failed after return period but before warranty expired then either contact manufacture or Amazon.
