I got my GGT on a 3 year lease this May and have been extremely happy with it. Letting it do my highway driving and watching it change lanes while passing is just entertainingly awesome and I can't wait to try the FSD coming "soon". I've never felt DDS2 was unsafe or tenuous. If anything, it is very conservative which aligns with my driving habits.
One of the minor firmware updates introduced a condition on my driver's window that required 3 button pulls to get the window back up, but another minor update (hotfix?) fixed it 2-3 weeks later. So many great things about the GGT which make the negatives stick out more. Engineering of the HUD display and it's windshield sun reflections seems very poor unless you live somewhere there is no sunlight or just drive at night. I'm actually fabricating a reflection dampening cover that hopefully isn't too ugly to solve that issue. I'm surprised Lucid hasn't beaten me to the punch on that idea but their hands seem to be full.
Contacting service is another huge deficit (by the way, my Lucid app dies when trying to schedule service on it). After 4 weeks of trying, I finally have an appointment at the Houston Studio to address a rattle in my door or column. It sounds like a 2' long connecting rod that has inadequate dampening. I only hear it at low speeds (<20mph) but since the car is so quiet otherwise, it bugs me.
As a nice to have, I wish Lucid offered upgraded floor mats as an after market option if not as original equipment. I've always gotten thicker carpeted mats for my previous cars but I've found no aftermarket manufacturers that are geared up for Lucid carpeted floor mats yet. For a luxury car, this seems like a no brainer.
I still fall in the "happy customer" category though and glad I tried Lucid as my first EV even though the 3 year lease is my escape hatch if Lucid fails.
