Air Version 2.9.0

[ME2U]

I copy this procedure to my phone "note" (from that forum) a year or so ago. Sadly I can't put a name on it.

"Fold down both back seats. Peel up the carpeted Velcro flap connecting the bottom of the folded part of the seat to the trunk. Underneath this you’ll see a module labeled TCU. Reach down and unplug the main connector (the only one with multiple wires). Wait a few seconds and replug. After a few minutes LTE and WiFi should return."

This started for me about two months ago. I was on 2.8.12 at the time. The move to 2.8.30 and then 2.9.0 on the same day, at first, seemed to fix that problem. But the last two days have had it happen a few times.

Same here....

This happened to mine last week but resolved after the car slept off the hangover. But how did you unplug the TCU? I didn't realize that it was accessible to the drivers.

Here is the post on how to reboot the TCU:

Thread 'DIY Fix for no LTE/WiFi connectivity bug'

Jan 1, 2025

Hi all. My 24 Air Pure recently decided to stop connecting to LTE and WiFi. There are a few reported instances of this on the forum. No amount of software reboots can fix this, and all users that have posted about this had to bring their car in for service to address this. After dealing with this for a few days, and the service only offering to see the car in ~3 weeks, I found a simple solution myself.

I read about a report or two that the technician fixed this super quickly after crawling in the back seat. Here is the solution you can try yourself if you face this issue.

Fold down...

You can't describe @helenewang real life situation as a molehill.

My comment was in response to saying Lucid “blew it”. Rather extreme. In relation to the update, It’s unfortunate for sure but everyone is making out like all vehicles got bricked. Lucid noticed the problem, pulled the update and issued a fix in less than 24 hours.

Wild. Bricking peoples cars is Everest my guy.

Heads up, it’s not the first time Lucid has bricked a car and won’t be the last. Just like Tesla, Rivian, etc. have bricked cars during updates also. Welcome to the world of software defined vehicles.

This is so true. My last EV, an Audi, couldn't do OTAs. You had to bring it into the dealership to install a software update. Invariably, they would have trouble with the updates, and would have to keep the car for 4 or 5 days (after initially telling me I could pick it up the same day). Every. Single. Time. So it's not like Lucid is being irresponsible or sloppy. This stuff isn't easy for anyone.

They need a TCU reset button

It is rather odd that the TCU never really goes to sleep so it doesn't really reset when this weird thing occurs.
It's happened to me once so far, where the car's cell, GPS and wifi all failed. No improvement with resets.
Was planning of crawling to the backseat and resetting the TCU but it just fixed itself after an overnight nap.

The chatter in one of the prior post about TCUs mentioned a tech stating this issue was common enough that one of the software plans for an OTA was to have the TCU automatically reset itself if it detects this fault. Apparently it's still TBD since that post was over 6 months old.

If this is happening to you regularly, you should get your TCU replaced.

Happened once so far prior to 2.9 update.
So we shall see...

I have been there and done that so many times on all sides of this situation with other software and other platforms. At Apple alone, Steve Jobs would reconstitute his ashes just so that he could roll over in his grave. Hopefully the new CEO will put his foot down on standards. This is not a perfect world. I know that. But still, Lucid must do better. And I think it can. Just imagine the reputation in a year’s time: “Lucid is the only EV maker with consistently reliable software. Only very minor glitches if any at all. All the others tend to be buggy.” I think that’s a reputation worth actively trying to achieve. I don’t believe they’re not trying, but I also believe they need to go the extra mile. I think they did a very good job in picking up the bug in 24 hours. It’s just that those 24 hours should’ve happened before the release.

We might have to disagree here. I agree with you that problems like this happen to all/most/some vehicles. But that doesn't really excuse it. And it doesn't make it easier when it happens to an individual who gets stranded when they need to go somewhere or get home.

However, on the larger scale, the problem really lies with the consumer though. Not to go down a rabbit hole here... But we have become conditioned to failures like this simply because WE keep buying products that have these problems. The only way to tell manufacturers that it's not okay is If WE stop buying them. Otherwise, they will keep pulling this crap and we'll have to keep dealing with them.

Until consumers stop buying things that regularly have problems (hardware, software, whatever), manufacturers will continue to be 'irresponsible or sloppy.'. And I'm not minimizing how difficult any component of this is. But if there's no viable option to make sure it's 100% solid, then WE either shouldn't buy it or accept the fact that there's a reasonable expectation of a problem at some point or another.

In an ideal world this wouldn’t happen, but with highly software driven vehicles there is always some level of risk with OTA updates. That doesn’t make it acceptable for the owners affected, and I understand their frustration.

What matters is how the company responds. Lucid identified there was an issue, halted the rollout almost immediately, and had a revised update deploying in under 24 hours. That’s exactly what you want to see when something goes wrong.

People are acting like this is a constant occurrence when Lucid has pushed over 85 OTA updates to the Air and this is the first major rollout issue I can recall that resulted in vehicles becoming inoperable. That’s actually a pretty strong track record overall.

Criticism is fair but pretending software defined vehicles will never have rollout issues isn’t realistic.

I'm typing a response instead of liking your reply because I emphatically agree with everything you just said. And you furthered my point. If software defined vehicles are by definition not reliable for OTA's or any other reason, then consumers should not buy them or understand that there are very real and potentially serious problems that can (and probably will) occur at some point. And, even knowing this and understanding that it can/will happen, everyone has their breaking point in dealing with software failures. Just ask @hmp10

 

[RAF42]

Had not rebooted my Air in months (except after updates) until today. Got in, Carplay would not start said "turn on Bluetooth". Showed off, but turning it on only resulted in a spinning progress icon, never would turn on. Tried Air reset, would not reset. Tried x-mic-brake reset and 45 seconds later it was back and Carplay started as usual. Only issue I've had in a long time, and first under 2.9.0.

It's funny you mention that, I literally had the same thing this morning. I've never had BT problems with my car, but this morning it was disabled and could not turn on. I did a logo reset and then it was fine.

Most, if not all of the people in this community are enthusiasts and are more knowledgeable than the average consumer. In general, we may be a bit more understanding and therefore forgiving of the situations we’re discussing on this thread. To the average consumer, an automobile is a commodity. An appliance. Appliances are expected to “just work.“ If we want higher adoption of EV’s in general and Lucid in particular, that’s the standard that has to be aimed for. If consumers “understand that there are very real and potentially serious problems that can (and probably will) occur at some point” that’s not a good selling point. This is a new industry. It is going through growing pains. Lucid is a new company. It is going through growing pains. Even though it’s true, it can’t be an excuse.

This right here. Not complaining about the problems, but agreeing with Lucid (and all SF defined vehicles) needs to strive for OTAs that do not brick a car.

I really believe that in the future, most/all cars will be electric. I don't know how long this will take, maybe not in my lifetime. But it will happen. Lucid NEEDS to convert ICE owners to EV. That is the only way it will flourish. Winning over current EV owners of other brands will not get them very far. The real potential customers are ICE owners.

One of the hurdles to that end is range and 'fill up' times. Lucid has done great at increasing the range and shortening the charge time.

The other is software issues. Most ICE cars do not have these issues like we see with EVs. Generally if your ICE car was working when you got it, it still is. Sure, mechanical things break. But people are USED to that happening. But they are not used to their car not working because of a software update that happened overnight.

The third thing is availability of repairs. ICE cars have the benefit of dealerships (for warranty repairs) being ubiquitous. Even in a small town. Or repair shops all over the place for out of warranty repairs. Lucid does not have either.

These are the things that most want fixed with Lucid. Personally, I am lucky. I live less that 15 miles to a repair facility. But it is the only one around in the Houston area and is way backed up. But I don't have to travel 300 miles like some folks on here do.

This. There are reasons, expectations, and excuses.

What I like about Lucid, among other things, is that they may set expectations that are lofty (and sometimes too lofty), but when they don’t meet them they usually have good reasons. Not always, but more often than other companies, in my experience, on average.

What they don’t usually produce is excuses.

Again, just my opinion.

The implication here, if you were to state the opposite, is that somehow Lucid is currently striving for OTAs that do brick a car. You and I both know that’s obviously not true.

It also seems obviously true that Lucid strives for OTAs that don’t brick a car. Clearly, in this case, they failed at that. But striving not to seems like specifically what they already do?

Total agreement here. The “sportiness” of the driving is what I think does that, personally, but everyone’s different.

I agree with you. It will just take time to get there. There was a time you had to crank your gas car every morning to get it started. Then you needed a third foot to press the clutch. Now you get in and ask Grok to drive you, if you were to ask half this forum.

It’ll get there. But the road to success is sinusoidal, always.

The third thing is availability of repairs. ICE cars have the benefit of dealerships (for warranty repairs) being ubiquitous. Even in a small town. Or repair shops all over the place for out of warranty repairs. Lucid does not have either.

I actually totally agree with you on this. I wish Lucid would publicize service manuals and the like, though I do understand that the uninitiated handling a high voltage battery or anything connected to it might be a bad idea.

You're right, I don't hear excuses from them. Crickets, yes, but not excuses.
