Heat affecting Lane Departure and Collision Warning Solution?

[Tim-in-CA]

Well, it's that time of year again in So Cal were temps are in the mid to high 90's and like clockwork, I'm getting the dreaded failure of lane departure and collision warning systems when my vehicle is parked in the sun. Today, while at an appointment, with the car parked in the sun for about 1 hour, when I got in the two below warnings popped up. They did not clear during my drive home (about 15 miles). This also affects speed limit sign recognition and the vehicle was stuck on "seeing" 5 MPH speed limit, mostly it just won't recognize any speed limit signs in this mode. In the past, I have also seen the failure occur while DCFC in similar high outdoor temps. When I reported this issue to Lucid last summer (and the summer before), they said that it was a known issue and there wasn't a solution. Has anyone else heard if Lucid has resolved this problem? I'm worried that the cameras/sensors will eventually fail (probably out of warranty) and I'll be SOL when this does occur.

Yea, seems odd seeing as others in AZ and in Saudi Arabia get significantly hotter than here more frequently. I'm going to put in a service request. I'm interested to hear what others have experienced when they report this issue to Lucid.

But in Arizona do you ever park for long periods of time (hour or more) outside with the windshield facing direct sun (no carport)?

Don't want to jinx myself, but this past Sunday, the car was parked from noon to 2 pm in direct sun and HA was fine afterwards. No warning.
Should add that I forgot to bring the windshield cover on that date, and wife thought I had memory problem.

I do use a sunshade (spring fold up type from Costco). It has happened with and without it on the vehicle so unsure if a sunshade exacerbates the issue. It should be noted that today when the issue happened I did have cabin climate control on the entire time I was at my appointment. The interior was cool when I returned to the vehicle.

Have you experienced this issue as well? I "think" that the affected cameras/sensors are those that are encased in the black assembly at the top of the windshield behind the mirror. It does get VERY hot! Pretty much the same as the back of the glass cockpit display.

While there are a few parking lots with solar panels covering spots, they are the exception. Parkades exist for some dense shopping centers or office buildings. But much of the time you are out away from home, you will likely be parked in sun.

I wrote because I get the error, even when it's in the low 80's, if I park facing east and get in the car at noon.

I'm in Phx and I've seen the front camera plus the 2 above but only for like 2 minutes from the time I start driving. started a couple of days days ago.

I live in Scottsdale also and when I leave my car in the sun for 4 hours on the golf course, I get the same warning lights.

Interesting.
My car has had a few significant issues, but not this one.
Your car tinted and with Lucid sunshade for the canopy?

Made a service appointment yesterday. The App showed no availability for the closest SC (Costa Mesa) all the way through August. I had to book Torrance (which is nearly 50 miles away). When they called me to confirm the issue, he said that the Costa Mesa SC was booked until mid-September!! When I Gove the Torrance SA the details of the issue, he said that he had never heard of the problem before (maybe he's new). Managed to get an appointment for July 7th ... we'll see what they find.

Yes all of the glass is tinted including the windshield. I also have the shades on glass canopy.

Florida owner experiencing the same issue. After speaking with support, it’s inevitable. The camera is exposed to direct light. The error goes away once the car begins to cool down. The camera sits on the other side of the rear view mirror.

I live in the Palm Springs area, so hot summers are the norm. I’ve had this issue each summer I’ve had the car, but this year it’s worse. Now anytime the temperature goes over 90, the camera fails. Customer service also told me they are aware of the issue with no solution. Quite frankly I find that ridiculous. It’s a safety issue! The cars are built in the desert, so it’s incomprehensible that they even have this problem.

It regularly happens to me too.

Well, once again, we owners try to troubleshoot but fail
I hope my luck continues to hold.

You should have it looked at by Lucid Service.

I am in AZ as well. I have my AGT for 2-1/2 years. It was 115F a couple of days ago. I have not seen the problem you flagged.

Yep ... I already have a service appointment for 7-7

I’m in Phoenix and get it daily during the summer. I’d be curious what the difference is. What year is your car? I have a 2022 GT.
