I just got a new 2021 GLA about 3 weeks ago. Every time I start the car in the morning, the clock is behind by 10-60 minutes (everyday, slightly different). When I re-start the car in the evening after work, the time is correct. I tried re-setting the system, and it seemed like it worked, but the next day, the clock was behind again. One time, I manually fixed the time with setting, then in the evening when the clock got self-corrected, it added the time that I manually added (ex. in the morning at 6am, the clock showed 5:45am, so I fixed it to 6am, then in the afternoon at 4pm, the clock showed 4:15pm). I already took my car to the dealer and they updated all the software, but the next day, the clock was behind again... Weird thing is, they gave me a loaner car (same 2021 GLA), and that car had the exact same issue. I think my battery is okay, I had no problem driving from Norcal to LA last week (5-hr drive)...Is anyone having the same issue? Or anyone has any ideas what is going on? I would really appreciate any tips!

Finally fixed the issue at dealers after third visit. They told me that there was a recent update for this issue. They manually updated the syst and its been working fine since then. Take your car to your dealership!

I had the same problem. I just kept changing it and eventually it kept the right time. Strange
