several folk have had this happen, myself included.
Service tech was out here yesterday harvesting data. I had an issue after trying the 2.0.35 update to .36 resulting in major alarms
I initiated the update, came back = car was done but update light back on? shows 0.35 ? Did it again...same result. Then few miles after update had failures. The engineers found a voltage spike in the data that was traced to a loose ground wire connection at one of the 12v batteries. After tightening the screw he pushed the 2.0.36 update again. It took 2 attempts but has resolved and shows 2.0.36.
I should note here that I was told by Lucid (care, not engineering) that my car was current so don't worry about it showing 0.35 after the 0.36 update but I don't think so.... and my tech agrees. I feel much better seeing the car is where it is supposed to be.
with what I know now I'd ask them to push the 2.0.36 update until your car shows "your vehicle is up to date 2.0.36 ". I wonder what others are doing? Will this effect the next update if you upload when your car is not already showing 0.36 ?
