After patiently, and at times impatiently, waiting for weeks and being assured by multiple Lucid employees that the 3.6.2/3.6.3 OTA update would resolve my largely inoperable Hands-Free Drive Assist feature, I'm disappointed to report that it did not.
I successfully installed version 3.6.3 today and took my GGT out for a test drive about two hours later. Initially, I thought the issue had finally been resolved because I didn't see the familiar crossed-out orange eyeball icon on the Clearview Cockpit screen. Unfortunately, that optimism was short-lived. After about five minutes of driving, before I even reached the freeway, the icon reappeared. I continued to my appointment, let the vehicle sit for an hour, rebooted the system, and tried again. Once again, after roughly five minutes of driving, the "Distracted Driver Alert Feature Unavailable" warning returned.
It looks like I'll be spending more time on the Customer Care line yet again. Incredibly frustrating...
