Hi everyone,
Is anyone else facing this issue?
Since January 2025, my Garmin Forerunner 255 has been randomly rebooting during activities, showing a blue triangle before restarting. Every time this happens, I lose the last 5 minutes of my activity data, and it can occur multiple times during a single run making the watch useless.
Even when idle, the watch occasionally restarts on its own, though that’s less disruptive.
I contacted Garmin support, but they told me I’d need to pay nearly €150 to replace the watch. I find this unacceptable. I purchased it in 2023, already had it replaced once last year due to a hardware problem, and now—less than a year later—it’s been malfunctioning for almost 7 months. Asking me to spend more money for a functional watch again feels outrageous.
For a product at this price point, I think it’s fair to expect a lifespan far longer than a year.
Has anyone found a real fix for this issue? I’ve tried every possible method I could find online (factory resets, syncing, letting GPS fully acquire for 15 minutes before syncing, checking for corrupted files, etc.) but nothing has solved it.
Garmin support has now stopped responding to me, so I’m stuck with a watch that feels unusable.
Any advice or proven solutions would be greatly appreciated!
Thanks,
