I have a Forerunner 955 Solar, and recently it started showing abnormal behavior. The watch randomly displays climb goals such as 6x, 7x, 8x, 9x, or even 10x my target, even when I am sitting still, like during breakfast. In addition, the elevation data during both cycling and running activities has become completely unrealistic and inaccurate.
I sent the device to an authorized Garmin service center in Brazil, and they provided the following technical report:
“We verified that the device has damage in the memory responsible for data processing and management. This component is overheating and cannot handle the current peaks during processing. Unfortunately, the memory cannot be repaired because it requires factory-level software programming and ID recording. Therefore, the only solution would be to replace the entire processing board, at a cost of approximately R$ 2,580 (around USD 460).”
Before approving such an expensive repair, I would like to ask: Has anyone experienced similar issues with wrong elevation data or climb goals? Is there any official Garmin support path or factory repair option for this type of problem? Could a firmware reinstall or hard reset solve it, or is it really a hardware failure?
