Drafty windows when cold?

What is the TSB number @marqie so we can see if we’ve had it done?

TSB-E0324-002-01

TSB-E0324-002-01

Does this TSB apply to all model year 2022-2025 air model tourings? Do the current 2025 builds have this fix? Can you post the TSB fix description?

Does this TSB apply to all model year 2022-2025 air model tourings? Do the current 2025 builds have this fix? Can you post the TSB fix description?

You can also simply contact your local service team and see if this TSB has been applied. It would not have been applied to *all* vehicles, as it is a TSB and not a TSC; a TSC is applied “the next time the vehicle is seen,” and thus is applied to every vehicle.

A TSB is applied only if an issue presents itself to either the owner or a service tech; if the issue does not exist, there is no reason to apply a TSB. Think of this as a “how to fix it” write-up and plan rather than a TSC, which would be more like a “we’ve made an improvement every car will eventually get.”

That means in order for this to have been applied, a service tech would have had to notice the issue (unlikely) or you’d have had to make a complaint about the issue (which would lead them to find the TSB; you can optionally provide the TSB number but of course do not have to).

Anyway, I contacted my service team and they let me know it had already been applied to my vehicle. You can also check your prior service invoices to see if the TSB is listed on it.

I just looked at mine and the description is “Front Door Wind Noise” Mine was completed in July 2024. Here are the notes:

Job: TSB-E0324-002-01 Front Door Wind Noise

Concern: The client states excessive road noise, requests updated door seals on all four doors. Please check and advise.

Cause: The client states excessive road noise, requests updated door seals on all four doors

Corrections: Inspected and verified all 4 door seals are properly installed. Found front LH and RH upper door trim seal is ripped. Removed and replaced LH and RH upper door seals. Test drove vehicle and measured the sound level at highway speeds (60-70mph) using a sound level meter. Found only normal wind turbulence when test driving vehicle. Cabin sound level was found to be at 64.8 dBA at 65 MPH. This is a normal sound level considering the vehicle is equipped with a glass canopy roof.

And, actually, perhaps someone should sticky this somewhere so we’re all on the same page in the future:

A TSB (“Technical Service Bulletin”) is merely a note from the manufacturers to the service center that is there to serve as a heads up, or warning. It's intended to prevent an issue, or clarify commonly ask questions, or to define the correct method of fixing an issue that may present itself in some vehicles. For example: There may be a TSB telling service departments not to use heavier oil than 5-30 on a stock turbo because the inlets aren't large enough to handle anything heavier on a cold start. Pertinent to Lucid, this front door wind noise inspection / fix is a TSB; it will only be checked and applied as needed, if the issue crops up.

A TSC (not a standard acronym in automotive, but usually called a Service Campaign, so context suggests “Technical Service Campaign”) is something that can be done to upgrade, repair, or make the car run better or more efficiently, but is not considered mandatory or a safety issue. Basically, your car is fine to drive, but when it’s at service you may want to have them do this. For example, an ECU flash might be a service campaign (or “TSC”). The front A-pillar speaker fix that must be applied before you get the benefits of the new SSP sound in v2.5.0 is another TSC.

Neither of these is a recall.

A recall is either a voluntary or federally-mandated order for the manufacturer to repair something because it has been deemed a safety issue. This is the only time an actual recall is generated. These are things that should be repaired because they pose a potentially dangerous malfunction. Sometimes they can be repaired via an OTA if it is software, and many times that OTA will have long been in your car before you even get notice.

Are all the service invoices available somewhere online or only via the individual invoices we get when service is done?

I just wonder why customers are having this issue with 2025 models. Doesn't seem right. You would think that this TSB would be applied going forward as a permanent fix.

 

[borski]

They are emailed to you via DocuSign. You can access them via your DocuSign account; if you don't have one, you should. It's free.

The implication would be that it isn't an issue on all, or even most, vehicles. Just some, and those are the ones you hear about here.

 

[Cosmo Cruz]

The latest diagnosis from the service center is that I should expect a cold draft from the window when it’s cold out,

 

[ColonelBadger]

I haven’t visited SC yet, but I’m doubtful this TSB fixes my issue. It’s not the door seal, but the window. In particular the top left corner.

 

[kapix]

I took my '24 AT to Natick, MA for this very issue and it was (not in so many words) declared normal and should improve in warmer weather. It continues and I believe that it is a design flaw.

Well that sucks. That’s my SC.

Here's the video by Bobby.

I ordered the weatherstrip material, and a decibel meter. Goal is to measure improvement in cabin noise at highway speeds as a proxy for the air draft.

I tried out the weatherstrip fix today. I have a 2023 pure without the soft close doors, so unfortunately many of the seal locations mentioned in Bobby's video increases the manual closing force for the doors. Because of the tolerances it was a lot of trial and error to figure out which pieces and locations would/wouldn't interfere with the door closing. For those of you looking to do the fix and running into the same issue, I actually found placing the seal directly on the door itself had the same effect and did not interfere with the closing force.

I already had service come out and fix the loose trim with the tooth clips that was causing wind draft, so while I have not experienced any more wind coming in even this winter, I still feel like there is a lot of wind noise at +70mph especially from my driver's side.

I don't have a decibel meter but after implementing the additional seals, it was a noticeable but small decrease in noise. Before I felt like the part of the wind noise was coming from the B-pillar, but now it "sounds like" its only coming from the wind going over the side mirror. I suspect that the seals are doing more to dampen sound coming into the car than actually closing any air gaps.

My guess is even when Lucid eventually fixes this design/improves manufacturing tolerances, if you don't have any music playing you will still hear the wind noise at high speeds, unless future models get rid of the physical mirror and go with a completely digital/aerodynamic camera instead, which will definitely generate some controversy

@Denali_Dane you need to do this! Thanks OP

What did they do to fix the draft?

 

[Adam]

Thanks for this! I brought mine to Natick as well, same result. They tested it in the shop with a smoke generator, no leak. Then took a test drive (after it had been warm in the shop for a while), no problems. But the problem persists.

Next time I'm there I'll point out this thread to them.

 

[jimbob]

What did they do to fix the draft?

The door glass runner trim piece was loose and protruding outwards. Even if it was pushed back in, it could eventually become loose again. My technician installed trim clips to hold the glass runner firmly in place of the mounting channel. If I recall correctly for good measure I believe he installed them on the all 4 doors.

Wow awesome I will give this a try

The original design had that top edge molding and gasket secured by just a pressure fit, but there is a fix that involves using positive attachment with clips. Lucid service calls these clips “claws,” and the part you’re specifically referring to as “door glass runner trim” is technically the “upper belt trim molding,” if I’m understanding you correctly.

And yeah, it should be covered under warranty if that is the issue; I don’t have a TSB number unfortunately, or know if one exists.

What is the TSB number @marqie so we can see if we’ve had it done?

TSB-E0324-002-01 is what @marqie replied.
