So, my elite series 2 controller went out on me, they received it 2 days ago per the...

Okay, so despite what the emails told me about it being 8-10 days shipping and 24 hours for delivery it can stop sale 2-3 weeks? For a replacement?

Hello!

Hope you are well. I'll be glad to assist you.

A replacement or repair request can take approximately 2-3 weeks from the time you send the device to the time you receive it, regardless of how long it takes at the service center, which can be 2-10 business days.

Best regards.

Yes, even for replacements, the full process can take around 2–3 weeks total, including shipping, inspection, and processing time. The 8–10 day estimate is just for shipping, and the 24-hour delivery applies once the replacement is actually sent out.I ask you to be patient.

Last month i bought a normal xbox one controller and the RB button suddenly started jumping 2 places everytime i clicked it and it wasnt useable so i went out and bought an elite series 2 controller and the exact same thing has happened with this
after a week of using it so if you dont get what i mean say im on the home screen tab and i click the RB button it would jump to the Mixer tab instead of going 1 place to the game pass tab anyone know why this happens

Same, after using my elite series 2 since it came out on Day 1, my RB doesn’t respond. When i click it with a slight touch on my LB, it responds, but when I do the same press, it doesn’t respond. This started happening 2 days ago out of nowhere. Any fixes?

Per the manual you posted, the warranty is "90 days for refurbished Xbox consoles and all Xbox accessories except Elite Wireless controller Series 2". Since an Xbox controller is an accessory, it has a 90 day warranty.
