Hello,

I'm writing about a problem with my Hammerhead Karoo 3. The screen has started peeling away from the housing, and it looks like a swollen battery is pushing it out. I first noticed it after my last ride on September 13, 2026.

I've stopped using and charging the unit until I hear back from you.

Could you let me know:
- Whether this is covered under warranty
- Whether a battery replacement is possible, and the cost
- Where I should send the device, or an authorised service partner I can reach (I'm based in the Philippines)
- Roughly how long a repair or replacement would take

I have a race in November and I'm mid-training block, so a quick turnaround would help a lot. I've been very happy with the Karoo otherwise — the screen and interface are the reason I chose it — so I'd like to get it repaired rather than switch.

Happy to send photos, my serial number, or proof of purchase if that helps.

  i had my screen pop-up as well last sunday. 
  just pack it and send it back to seller if under warranty. isn't it obvious? 

  where did you buy it from? how long ago? they are covered by manufacturer warranty or just open a ticket here. since 2024 they are covered by sram warranty policy. it may vary depending on your region.
