Noticed your Uconnect 8.4 clock running slow? You're not alone. The other day, I realized that the clock in my Uconnect system was losing several minutes per hour. At first, I thought it was a one-time glitch, so I manually adjusted the time. But a few minutes later, it drifted again—off by several more minutes. Even after performing a full system reset, the issue persisted.
After some trial and error, I discovered a soft reset solution that worked. Days later, the clock remains accurate, and the issue hasn't resurfaced.
How I Fixed My Slow Uconnect 8.4 Clock
This simple fix worked for me and may work for you too. Here’s how to perform a soft reset on the Uconnect 8.4 system:
- Press and hold both the Volume and Tune knobs simultaneously.
Hold them for about 10–15 seconds until the screen goes black, then release both buttons.
- Wait for the Uconnect system to reboot.
This can take a minute or two. The system should restart to the default interface. - Set your clock again.
After reboot, the clock may reset to12:00. Go into your Uconnect settings and manually set the correct time. - Monitor the clock over time.
After several days of normal use, the clock on my Uconnect 8.4 has remained accurate and no longer drifts.
Why This Works
The Uconnect system occasionally suffers from minor software glitches that affect non-critical modules—like the clock. A soft reset essentially restarts the infotainment interface without wiping your saved data or settings. This refresh often resolves persistent issues like clock drift or Bluetooth connectivity problems.
Final Notes
If your Uconnect 8.4 clock is still running slow after this fix, you might consider the following:
- Ensure your vehicle has a stable GPS signal (used for time sync in some models)
- Check for available Uconnect software updates
- Perform a full factory reset from Uconnect settings (as a last resort)
Hopefully, this quick reset works for you like it did for me. Let me know in the comments if you’ve run into similar issues or found other reliable fixes!
