Garmin Fenix 9: 94 reported bugs in a month — what owners need to know

Fenix 9 and Fenix 9 Pro have been on sale for about a month. During that time owners, reviewers and forum users have reported 94 distinct bugs. The5krunner counted every report it could find across Garmin's forum, Reddit and reviews, then grouped them by frequency and type. Seven bugs were listed as fixed in Garmin's 6.48 update, released 15 September.

Which problems are widespread and which are isolated

• About 30 of the 94 issues are "widely reported" — meaning multiple owners or several reviewers noticed them. Around 15 have two reports each, and roughly 40 are single-owner reports.
• The author excluded about 20 items that turned out to be settings or deliberate design choices (for example, AMOLED screen dimming or Silent Mode behavior).
• Nothing in the list is reported to have bricked a watch.

• Activity crashes and freezes. Multiple reports of watches crashing during navigation, freezing mid-activity, or crashing repeatedly on a single route (one Reddit post cited 10 crashes on one walk). Crashes can cause recordings to miss minutes.

• Pool swim tracking. Several owners reported missing 10–34% of pool lengths.

• Music and Bluetooth reliability. About nine owners reported music crackling, dropouts, and AirPods disconnecting repeatedly during runs.
• Button response and map performance. Owners report a slow Start button reaction (two to three seconds) and map lag that's improved over Fenix 8 but still behind competitors.

• Garmin released software version 6.48 on 15 September. It listed seven fixes, mainly addressing inReach, calls and volume issues. The update was rolled out to roughly 20% of watches initially.
• The activity-crash issues are not listed among the fixes in 6.48.

Context: is this normal for Garmin launches?

• The article notes similar rollouts for past Garmin launches. Fenix 8 and the CIRQA launch also produced largos lists of reported issues. Some bugs are inherited across models because they share software.

• Suunto and Coros are called out for faster map drawing and simpler, more reliable behavior. The trade described is breadth of features (Garmin) versus speed and stability (some rivals).

• If you depend on navigation and activity stability, watch reports of recurring crashes closely and consider holding off on heavy use until further firmware updates land.

• If you use a Mac for map installs or recovery, be aware Garmin Express limitations on Apple Silicon are a confirmed problem.
