Front left light malfunction

[Luci]

have logged a grand total of 338 miles and today an alert that the front left light has malfunctioned. Sure enough, the front long vertical light is not working and the turn signal blinks fast inside (like any other car when the light is not working). Called service and they are going to send a tech. My engineer husband believes likely a loose wire, but we have no idea how to troubleshoot. Service rep says the wiring is integrated and not accessible, logical husband then responds, "so how is the service tech going to get to it?" Its a conundrum to play out when the tech arrives next week. If any one here has any suggestions, would love the feedback.

Had same issue. They are taking the car on Monday to fix it along with a couple of other items.

Brought mine in yesterday because the front passenger headlight was working intermittently. Diagnosis was bad headlight module, they said nothing wrong with the wiring. Module was replaced but engineer needs to sync the new module to my car. Hopefully it's done today.

No luck with the synchronization of the module to the car, apparently a firmware issue they are trying to fix through the engineering team. You'd figure this should be a simple plug and play, but apparently not.

Prime example of what the Lucid production hell article quote about over engineered is about.

Over-engineered sounds like German cars, which are the mark of quality! I can dig it!

Yeah that’s required my prior Mercedes to need 4 service visits in the first 6 months of ownership to troubleshoot and replace airbag ECU.

Had the mobile tech at my house today because my GT was delivered with the left front turn signal light not functioning. Same issue as above. He discussed with the factory and found out this is a known issue with the vendor who supplied the LED light board. I will attach a picture of the board and assembly. Basically the light board with 32 small LED lights on it has a four pin connector on one end. The board is mounted inside a plastic housing with a hole/port designed so the wire harness can connect to the four pin connector. Unfortunately the port is at a 45 degree angle to the board, but the pins come off straight. So in order to get the pins to line up with the connector plug they must manually BEND the board to the 45 degree angle. It is essentially a circuit board and doesn’t like to be bent. Mine broke during the bending as have others. The mobile tech tried to solder the connector pins back on to the board with four wires today, but after reassembling the entire front end, no luck. There are no available replacement LED circuit boards.

Not sure what the solution will be for this. I suspect after looking at the LED board that many of these will need to be replaced - and probably will end up in a recall situation.

On the bright side, the mobile tech was a very pleasant guy and we had a fun afternoon talking about the engineering (over) of the Lucid. He worked repairing Teslas for 10 year before joining Lucid.

And as a nice parting gift, my frunk will not open now. Tech said while he was putting the bumper back on how much a problem having two front latches for the hood has been. If one is even slightly off the other won’t work.

Looks like a f**k up. But shouldn't bending the pins be enough. You cannot bend circuit boards.

Oh boy. Note to self, if turn signal light quits working, ignore it until there’s a fix/recall. Thanks for the heads up on this one, I’d rather have a working front trunk than a working front turn signal.

How can this 45 deg possibly be missed from the factory/subvendor especially if its on numerous cars? Or from the service center PDI for a known issue? Concerning news ..........

 

[Bunnylebowski]

It doesn’t sound like it was engineered that way so much as they made the housing and the circuit board didn’t fit so that was the “solution”. I’ll keep reminding myself about all the amazing engineering things they pulled off so I don’t think too much about this screw up.

 

[dale246]

My issue was the passenger headlight - whole unit needed to be replaced and then the software reloaded. It was in the service center since last Friday and just got it back today.

Is this a DE or AGT.

Scary that four people on this forum have already had problems. I’m not an engineer and all for rigging some thing things to make them work. But headlights in a 140k car? That’s seems like something that should have been fixed.

I mean, they are on their third windshield already too.

Right?

I've never seen anyone bend a pcb board. Surely he was instructed to bend the pins and goofed. If he had the right pins, he could have easily removed the old pins and soldered 45 degree ones.

I'm trying to visualize the piece of plastic with the connector, and the PCB in place, to get an idea of the pins relative to the connector. IE based on the spacing was bending the board actually going to get the pins into the connector? Or was the actual fix bending the pins.

My gut is screaming the tech made a big boo boo.

Either way you need to report this higher up the Lucid engineering chain. I don't know if 1. The tech misunderstood the instructions or if 2. The instructions were poorly relayed.

In both instances someone needs to be made aware so this doesn't happen to anyone else, especially on a PCB that is on backorder or low supply.

If this truly is the solution, I'm flabbergasted.

I’m with you on the problem/solution. They are truly bending the board at the factory. It appears that bending the pins alone wouldn’t reach the connector. They actually remove the plastic from one side of the board at the bend spot to allow it to bend easier. Which is really strange because the board should never be bent.

I suspect its as bad that its well known and theyre supposed to bend the pins by hand as repair fix. And they dont even have suffient workman ship to do it. You can do it if you first take out the pcb in your hands and then use a plier and carefully bend one pin at a time, and if needed, two pliers. But the pins may not be long enough. Factory says its a known issue, so why wasnt this on the tech's work order and best way to repair it -- highly disorganized. Mom and pop home garage shop? Are we starting to see the true level of Lucid quality? Just by memory reading this excellent forum, it seems almost every car have issues having to go back to the shop somtimes more than once.

I see what you mean. Yes, bending the entire board at the connector pins is completly unacceptable, and if it doesnt brake right away, itll never hold up.
