My first hand experience with AM radio reception in the Bolt...it's great..much better than my Prius and my wife's RX330. You have links to the "many complaints about poor AM reception in the Bolt"? Again...maybe the Koreans know how to make AM work in EVs.
P should have full red glass since you paid more for the car. P for premium.
Okay you made me go out and check. VIN 730XX P3D+ 8/2018 and only the front is red glass, rear does not do that when I sprayed it with water. How certain are you that this is the UV blocking properties of the window? Previous cars I've owned with that UV blocking coating did not rainbow like that.
Ah darn it! Someone else with a recent P model
Had full red on both glass. So it just felt like it might have been the Ps got special treatment. But maybe not the case.
No one is for sure if the red signifies anything. If it does. It’s for inferred (IR). Not UV.
UV should still be there, it’s just heat rejection IR that’s not. I’m having my full rear glass tinted to black the whole thing out and double up on UV. Not too as worried about IR as the air conditioning is always on when the kiddos are in the car.

Give me some sugar baby
We’ll probably never know the full story on this one but this kind of reeks of Tesla cheaping out on another component of this automobile to improve their margins.

Performance 3 #72xxx doesn’t have the orange effect on the rear window. Only the top. Kinda disappointing because it looked really slick, but it’s minor.

Lots of Volts....one Bolt thread. Guess I was lucky with my 2018 build....AM and satellite are awesome....no issues with reception nor sound quality. Guess the Koreans figured it out.
A few weeks ago right after delivery, we noticed that only the front half of rear roof has orange glow when wet. It is a RWD, VIN 39xxx, July 2018 build. This thread is driving me crazy, so yesterday, I was ready to take a hammer and chisel to get a few pieces of glass samples from each window then put them through IR spectrometer in my lab...
Then my 16 year old handed me a TV remote (infrared LED), and did following:
1. go into garage and close all garage doors, only leave a dim light on
2. point the TV remote (pressing one button) to his phone with camera app on, he saw bright LED (IR light detected by camera sensor) on his phone
3. put side window between remote (outside the vehicle) and phone (inside the car), repeat #2, he saw LED showing up on his phone just as bright without the side window
4. repeat #3 for front windshield, he saw LED on remote just as bright without the windshield
5. repeat #3 for rear clear glass roof (rear bottom portion, no orange glow), he saw LED on remote much dimmer, but visible
6. repeat #3 for rear factory tinted glass roof (front top portion, with orange glow), he saw LED on remote dimmer than #5, but still visible
Conclusion: on our model 3, the rear clear portion of the glass roof does have some kind of IR rejection capability. It is much better than front windshield and side windows. To determine exact transmission rates at different IR wave lengths, someone has to take a hammer to their model 3 to get a few pieces of glass samples from each window then put them through a real IR spectrometer. I decided not do it on ours after my son's test.
Cheers

What remote did you use? I tried 4 of them and my phone camera didn’t pick up any IR out of the remotes
It may sound silly, did you press a button on your remote while you are point it to your phone? Also, make sure they are not bluetooth remotes.
Otherwise, I would suggest try a different phone or a digital camera. Most remotes use the same 940 nm wavelength LEDs.
Haha I did. But I realized the iPhone back camera has a IR filter built in. Now what phone / camera did you use?
Ok I dug out a old Nokia cell phone and that camera picked up IR. Tried it on all my windows, the front windshield and side door windows, the phone picked up the IR.
The top and rear glass did not see any IR
@dong99 did you try it on the top glass above the drivers seat? How did that compare to the top of the back seat vs the rear back (behind the back seats?)
