Okay, experiment completed. I had posted earlier that our Dream P was intermittently stopping charging short of the 80% charge limit we set when plugged in at home. There were suggestions that the problem might lie with our wall outlet. As we have another 240-volt NEMA 14-50 outlet in our garage that we use to charge our Tesla, we swapped the two cars on the outlets for the past several weeks. During that time, both cars charged up to their 80% limit consistently.
Today, I found that the Lucid, which was still being charged off the outlet we usually use for the Tesla, had stopped charging during the night at 76%. In past incidents, the car had stopped charging anywhere from 52% to 76%. Also, these incidents tended to come in clusters, with days or weeks elapsing between incidents and then several occurring almost daily.
At this point, it seems that the issue is either with the Lucid or with its charging cable. We are leaving Sunday (three days hence) on a road trip where hotel reservations were made where L2 charging was offered. I'm now worried that might have been pointless, and we'll still have to rely on DCFC where we can constantly monitor the charging to be sure it doesn't stop prematurely. (I know we can monitor L2 charging via the app, but that's a bit inconvenient when we're trying to get a night's sleep on a trip.)
Someone posted earlier that Lucid Customer Service told them this was a known software issue, but the Service Advisor to whom I talked said they were not aware of any such issue.
Can anyone shed any light?
