I bought a defective xbox series x controller Feb 14, 2024 from Target and they wont...

most retailers have a 14 day return policy,

Microsoft controllers have a 90 day warranty which is also expired.

Bought a new unopened Xbox controller from target on January 29, 2024, and it came with a game pass. I tried to redeem the game pass today (April 28th, 2024) but found out the code expired on 12/31/23. Would it be possible to get a new code?

No, in these instances its not possible to get a new code as far as i am aware. Sometimes that sort of thing just happens if its been sitting on a shelf for a while. Its unfortunate but it happens.

I bought the Series X back in Feb. 2021 and I think the 3 month warranty has been passed (assuming it starts upon purchase). I have a "Microsoft Limited Warranty" that will expire on March 2022 but I'm not sure if that covers hardware. I did have a glimpse at the "out of warranty" repairs but did not see a controller listed except for the Xbox Elite Controller Series 2 (I'm US territory).

"The Xbox series S is a more than capable gaming console with an excellent power to price ratio that targets 1440p and can output upscaled 4k.

As a result you should not be getting significantly noticeable 'pixalation' over the series x."

The original poster bought an Xbox One S, not a Series S and was comparing it to an Xbox One X, not a Series X.

My elite series 2 rb button doesnt work and i cant find a replacement button how do i fix this

Microsoft knew the controllers were defective and still sold them as a good product. they wont do anything to fix your controller because its most like out of warranty thats why the warranty was so short. The whole elite series 2 was a scam
