Rear Window Replacement—Crack from Hinge

If you look under the trunk lid you will see the distance between the trunk hinge and the window edge on both sides is approximately ¼” gap. From Lucid these are called floating hinges. As a warning do not push on either side to see how close you can get the hinge to the glass as you may crack the edge!

This happened when our car was getting the two-year service at our home. I was outside with our Service person, Mike ,and was talking and tying my shoe with my shoulder leaning on the trunk and I was told not to do this ---sure enough it cracked—took over a month to explain to my insurance company that this is not a typical glass repair—costing over $4,700 plus transport from Akron to Michigan. I had vaguely remembered Mike saying something to me at one point –if I would have seen how close then it would have made more sense to me.

This is upsetting and from my perspective-a design flaw. I understand this has happened to others and was told this happened to an owner in Michigan when it was very windy pushing the trunk to one side when opened. Part of the fix in my case was putting a shim on the edge of the hinge, so I really question the distance during assembly as I never looked.

With this said, Lucid needs to have written communications to all Air owners---maybe warning stickers on the trunk? I am fairly nervous this can happen again!

I did correspond to Lucid Customer Service including pictures showing the hinge rubbing against the window. The final correspondence was rather snarky with no warranty solution:

“Charlie,
I appreciate your perspective but my understanding is that you were advised of the potential for damage based on leaning on the car but subsequently caused the damage. It's unfortunate for sure.
While you can, of course, go to the forums, at this time, we feel that taking your car to a bodyshop and working through your insurance is the best course of action.
Thanks for being part of the Lucid family.

On a positive note, this new window is not distorted as I had accepted the original window as “normal”. Looking through the back window always distorted cars, but the new one does not.

When our car was returned which Lucid covered the return trip, it was received in immaculate condition inside and out. Jason communicated on warranty items that were noticed when he received the car and were fixed-so an excellent experience working with Jason and the driver returning the car.

We really enjoy the Lucid-a special car! We can drive from Akron to Cincinnati to visit family with about 20% battery left and do not have to go to Electrify America charging stations since my son was nice to put a charger at his house—not the expectations Electrify America could charge to 80% in 20 minutes. Besides a late delivery-caused by the transport company which caused us not to be able to take the $7,500 tax incentive, and putting up with some software issues mostly seem related to the key fobs and phones and a learning curve on our side. We are getting close to 30,000 miles—have the upgraded stereo system, glass canopy, and Dream Drive Pro—the newer update for hand free makes it even nicer!
 
Service broke the hell out of my car twice. Broke the glass roof, rear glass, and that black brake light thing on the trunk housing. They replaced it all but man that was a hassle.
I'm definitely not blaming the mobile guy, when I inspected the piece of the trim that had broken off, it was VERY brittle and broke in half with minimal amount of pressure. I don't know why Lucid didn't use injection molded plastic for this piece. Maybe tooling cost was going to be too high due to the complexity of the design.
 
Do you have any details on the shim they installed. Both hinges on mine are pretty close and one is VERY close to the glass. Mobile service was here today and had to replace the wiring harness that goes in the trunk deck lid and he hadn't heard of the shims. Unfortunately, he broke one of the black trim pieces in the trunk which is oddly a very brittle painted fiberglass type material. He said it most likely has to go to the body shop as they need to remove the decklid to replace the trim ... pretty amazing how cars are NOT designed for repairability.
Hey @Tim-in-CA I never saw the shims, only read about them from someone in this or another thread about broken rear windows from the hinge When I had my S7 Audi fixed, we joked it was two steps forward and one backward - something new was always broken from the last repair...
 
The trunk was open when I leaned-all 160lbs of me with the other foot on the ground so if it was actually .250" distance-not much with an open edge of glass. The shim fix and possibly design change on newer models points to probably a known defect. I am not one to abuse and be careless.
 
Update. Lucid service ordering the parts and will replace the rear window and pieces of trim that have to be replaced. I am out of the country for a month, so will be done in April.
