Lucid Gravity 3.4.0 software update

New bugs today, extremely frustrating. Both blind spot cameras stopped working, and a Redundant Lighting Fault error (new too, but who knows if related) at the start of a four hour drive, sunny and warm. Also, DDpro at 76 mph on a fairly easy curve lost control and crosses into another lane. I stopped trusting it for the rest of my drive.

While my first guess would be hardware, I wouldn't rule out software since they touched the blind spot cameras for increased resolution. I will reach out to Service tomorrow morning.

And later at my supercharger stop, a guy asked me if I would recommend my car for his wife? (I don't want to derail this thread, so let's leave the answer out)

Oh man, I’m so sorry. I thought I was the only one with a similar problem. In my case, I was on a highway, and the same 3 warnings popped up (high beam, lane, and other). The car was clean (no snow), and suddenly it disconnected my ACC, making my car break hard on a highway. The dude behind me thought I was break-checking him.

That was prior to update 3.4.1, but after installing the update, the same thing happened, but this time I was ready to accelerate. I will never trust the adaptive cruise control ever again, and I’m working on returning it or selling it.

Today, my brother-in-law asked me the same question: if I recommend Lucid, I guess you know my answer.

I do wish it had a more gradual transition dropping out of ACC when REGEN is on. I even submitted an email suggestion for that because it is rather harsh and difficult to get the speed matched with the accelerator pedal before it starts to slow you down hard.

It's a little more gentle if you turn off REGEN when using ACC (you can make that the steering wheel joker button), but even that doesn't do a smooth coast when cancelling out of ACC. That's a process they could really stand to fine tune because it usually results in a harsh transition the way it stands now.

Agree. What I do to avoid it is I accelerate the car about one to two mph faster than the cruise setting, then hit the X to cancel it. No issues then with the jarring cancel, but yes, it does need a way to do it better.

Yeah, that's what I had to do in my Mach-E and now my Macan. I just haven't tried it enough in the Gravity to get good at it yet. But I'm finding it harder to do in the Gravity because of the stiffer accelerator pedal that doesn't seem to have a lot of play in it. Makes it harder to pinpoint the speed you want. I wish they would widen the range of motion in the pedal (and lessen the resistance on it a little).
 
Remember Air had the same issue when it slows down instantly rather than gradually after disengage with DA/HFDA. They have tuned that with updates. I’m hoping the same with Gravity as well.

My solution is to bump the cruise down a few until I need to press the accelerator to be at the speed I need, then cancel. Since in most cases you need to cancel it’s because you need to slow.

Hearing how stiff the pedal is makes me not consider getting a Gravity until they change that. I once got put in Cruise Control Prison because I had to accelerate to above 90 to get out of the way of a semi truck moving into my lane (😡) and had to press the accelerator with my foot for the next 800 miles. And HOLY COW my leg ached.
 
I have a 48 amp home Tesla charger that was charging at 11kW and might slow to 8kW pre software update. Now that the new Update has been installed the charging at home process has slowed and as the battery reaches 70% overnight it slows to 4kW. Anyone else notice this change? rebooting doesn't affect his.

Do you have an Air or Gravity?

To me there is a range of motion in the pedal. I find that the stiffness or responsiveness of the accelerator pedal is determined by the regen setting. When regen is on high, the response to easing off the pedal is much greater than when regen is set to standard. I occasionally have regen at high for local driving at slower speeds, but I set it to standard for highway driving.

I also gradually increase my speed to match or exceed the set cruising speed before disengaging ACC.
I'm trying to minimize the amount of regen engagement to hopefully avoid having the brake lights come on, which is my greater concern.
I don't want to appear to be brake checking someone, as mentioned in another post.

Negative. Held 11kw to 80% for me last night. I have the Tesla universal charger too.

I have exact same symptoms (with 48A ChargePoint) as you and just sent the GT to service center with screenshots of this for them. I saw they charged the car as soon as they got it and could see them reproduce it. Might take them some time to debug I guess especially since my service center is swamped but will update whenever I get any info

Interesting on the difference between STANDARD and HIGH regen. So in HIGH the pedal is even stiffer? Not that I'm likely to use it. I find STANDARD regen already pretty strong (and the pedal fairly stiff). Of course, my Macan regen is on the lower side, so anything compared to it is gonna feel strong. So much of this is just comparing to what we're used to in other vehicles, thus subjective.

I try to match the speed with the pedal before disengaging ACC too, I'm just finding that harder to do in the Gravity vs the Macan or Mach-E before it. I'm sure I'll get better at it. but I'm hoping Lucid does some fine tuning to make the transition easier (which should also avert brake lighting). Be nice if disengaging ACC triggered a temporary coast then ramp-up of regen, over maybe 5 seconds, giving us more time to find that perfect pedal pressure before it starts applying hard regen if we haven't found the right pressure immediately. It's often a jerky transition now, especially for passengers.

I know we can somewhat do that ourselves by turning regen OFF temporarily, but who wants to keep switching regen on/off every time we use ACC? Something built-in to ease that transition would be better, especially for a luxury car.

I actually tried that the other day (turning regen off before disengaging ACC), and I was surprised it wasn't much better. Instead of coasting, the car still slowed itself down, rather significantly. That surprised me. Not as much as with regon on STANDARD, but it sure wasn't coasting like I expected.

Read back a while and you'll see the software update crippled quite a few Gravity owners with issues like this. I have 80a charger which gets reduced to 30a after 15-20 minutes, which is way slower than their NEMA 14-50 240v home charging cable (40a) which they provide to us. I use to be able to hold at 48a continuously prior to the update. Now I can't find a number which I can hold at. Everything level gets the throttled eventually since the last update. This throttling has happened on my charger, their service location charger and public level 2 chargers.

Yes, regarding regen on high being stiffer. With regen on high, to me, if you just completely lift off the accelerator pedal it's almost like emergency braking; quite drastic. Just my opinion and experience. You're correct about the subjectivity.

The option of temporarily turning regen off is an option currently, but I agree on the hope that Lucid will provide a solution to allow better coasting.
A viable solution will be tough. While we may not want the stiffer accelerator pedal or sudden deceleration, there are emergency instances when that sudden deceleration with brake light activation is exactly what is needed.

I believe other owners have emailed the sw feedback email address about the need for improve; perhaps we will see something in a future update.

I think we're talking about different things with the term "stiffer". You're describing the regen being stronger (i.e. slowing the car faster upon lifting up on the accelerator pedal), which yes, is what stronger regen does, like harder braking.

By "stiff" I'm referring to the movement of the accelerator pedal itself, i.e. how much foot pressure it takes to move it. Some accelerator pedals move with less resistance, and others take more pressure (what I'm calling "stiffer"). I find the Gravity to be on the stiffer side, at least compared to the other vehicles I've been driving. I also find the range of motion to be on the shorter side, which makes it trickier to find just the right pressure for a specific speed. My Mach-E would do both of those if you switched it to Sport driving mode, but in their Whisper (Smooth) drive mode, the pedal got less firm and the range of motion wider, which I liked much better. Kinda wish the Gravity would give us a way to do the same. Right now it's more of a "Sport" pedal.

I have a 2026 Gravity. the charging time has significantly increased since the update. It use to start at 41 kW and at 70% lowered to 8 kW but no it lowers sooner and was at 4 kW at 70%

OK. Sort of like pedal sensitivity.
I can't say I've noticed it being overly sensitive.
However, my Gravity is my first and only ev, so might right foot isn't has seasoned as yours. :)
