After a year of trouble free use, I've got my first problem with my AGT: Dream Drive Pro stopped working. At first, only HFDA didn't work. Now I can't even get cruise to work. At first, the display showed my car off to the side of the travel lane. Then I did a brake-X etc reset and the deisplay showed the car centered in the lane, but was frozen there (the brake lights/turn signal did show properly).

I am not on the highway much, so I don't know when this occured. I did notice HFDA wasn't available on an earlier brief trip, but I can't recall with any certainty whether cruise worked or not.

I checked/cleaned the sensors, but beyond that I am at a loss as to how to troubleshoot this.
 
Not sure if its the same issue but just sharing experience FWIW.

During drone/missile attack in UAE, GPS spoofing and jamming is a common occurrence, my Lucid Air GPS is better than Tesla but when GPS gets confused, it would not recognise I am on a highway where DDPro DA is allowed. Some Tesla shows they are over the ocean or slams the brake on highway with map shift to lower speed limit road.
 
I had a similar issue where not even adaptive cruise would engage. Then a few days later it was randomly all working again.

I know you said you did a reset, but I’d also say give it a day or two and try it again before concluding you have a bigger issue.

They were pretty much all intercepted, I had no idea this country has a such strong air defence system.

Also GPS spoofing and jamming happens all over the world. Fun fact do you know now days we fly jet often with GPS off and rely on trust worth ground nav aid?

Sounds like a job for service. See if they can't send a mobile tech to diagnose, but more than likely it will require a trip to your local SC.

I've had similar problems and found out that my cameras are touchy and require recalibration more than they should...

Fortunately, I have a mobile tech coming next week. If it doesn't resolve by then, I'll have them take a look.

I was hoping this would clear up before my 5 hour trip tomorrow. 😬
 
If you've tried a reset and already checked the sensors for obstructions then I think Lucid service is your next step. Your sensors may need alignment, or the ADAS computers may not be in agreement.

If this was caused by some sort of GNSS interference, OP's nav system wouldn't be functioning either along with a myriad of other non-vehicular services. I would be astonished if it was a factor here.
 
Last trip to Phoenix had a hiccup like that
You could do anything except engage it
You could set speed, raise/lower the speed but couldn’t engage
Rebooted the car and even stopped for a snack and charge but nada
Next morning all was good
Never happened again
 
So on the return trip today, everything was operational! I guess some combination of resets, deep sleep and patting my head while rubbing my belly worked. It was very nice to have driver assistance on a long drive 👍

You don’t appreciate how useful and capable Hands Free Highway Assist is, until it and everything else is taken away from you.

It hasn’t happened in several weeks, but I would have this happen too in my Sep 2022-build Air GT. I’d stop for a potty break on my 140 mile commute to work, jump back in my car and get back on the freeway, re-engage Driver Assist, then, nothing. Not even basic cruise control. The remaining 90 mile drive to work would be a real chore.

Then, after a day or two, or maybe three, I’d get back in my car, start my 140 mile drive home, and lo and behold, it would all be back! All of it.

As I said earlier, it’s been several weeks now since Driver Assist just randomly disconnected, never to be reengaged. Lately it’s been rock solid reliable. I don’t know what changed.
