Tag @Yarbo-Forum to see what is up with this. 23 days is not good. Hope they get back to you ASAP.
Iām trying my luck here. I usually get super fast replies and excellent service from customer support, but this time itās been almost a week without a response. Iām also getting a B0004 battery error. Has anyone else had this error, reached out to customer service, and gotten a reply?
Iāve had little interaction with Yarbo about this issue Iām also having, though they have been very attentive to previous issues for me too. They will suggest a hard reboot (disconnect battery 5+ min, reconnect and hold power button 1 min, etc.) and also trying different modules. I havenāt any idea whats going on behind the scenes for solving B004. Though perhaps one of these early troubleshooting tips will help. A little more transparency from Yarbo would probably be helpful. As Iām sure youāre realizing, we canāt exactly bring these things to the local small engine or computer repair shop.
Sorry for the delayed response. Iāve followed up with the team and asked them to review your case as soon as possible.
Iāve asked our team to review your case #205722 as soon as possible.
Weāre currently experiencing a ticket backlog, so our response time may be slower than usual. Sorry for the inconvenience caused, and thank you for your patience.
Thanks all for reply! Iāve tried all these steps with no luck. I will wait for further guidance from yarbo support
Maurice,
I had similar issues a few weeks back. At the time customer support wasnāt as back logged as they are now. There was quite a bit of remote diagnostics done, and it was not made clear to me what was discovered, but I do give them credit for trying everything.
They replaced the battery, the SAM module, and eventually the Core. On the positive side, the issues you described are gone. However Iām having different issues with my replacement Core.
I doubt any of this helps you, but I at least wanted to let you know that someone else had those issues and eventually got those issues resolved.
Good luck,
Jeff
Thanks for the note. To be honest, I donāt have an idea of what should be done, just that doing nothing wonāt solve it. The simplest explanation is something on the core. Iām sure theyāre seeing that as a last resort for shipping cost (and new issues as you mentioned), but if they canāt figure it out remotely I see no good alternatives. If only the ābrainsā were more modular and able to be removed and swapped out! That would be the best improvement for the next generation.
Well Profile - Yarbo-Forum - Yarbo Forum , itās been nearly a month with no resolution to this issue. Aside from a claim that it was fixed remotely when it wasnāt, Iām not clear this has even been worked on. This seems excessively long for a warranty repair/replacement. I paid too much for this thing and Iām frustrated.
Sorry for the delayed response.
Iāve asked the Field Service Engineer responsible for your case to review your ticket as a priority. We will follow up with an update as soon as possible.
Thank you for your patience and understanding.
36 days and still waiting for a warranty fix/replacement. 
40 days out and Yarbo Support said theyāre sending a refurbished core to replace my defective core. Unfortunately, they also said they have no inventory and it will be weeks before this happens. At this point, I wonder why they donāt just send a new one. By the time I am able to mow my lawn again, the Summer will be nearly over.
Hi there, sorry for the confusion caused. You should have received the tracking number by now and can expect to receive the replacement soon.
Thatās good to hear. I will report back with my experiences with the refurbished unit once it arrives.
