So the red LEDs for collision warning are recessed in the air vent on the dash board close
to the windshield. That doesn't tell us if there is a reflective coating on the windshied, however.
I think it does. The only reason the reflective coating would be on the windshield is to reflect light from those LEDs.

OK, so I have the red LED collision warning, have the Light Ash Gray, Ceramic White, and Perforated Leather trim, and perhaps a reflective coating on the windshield. They call this the perfect storm or you can't see the road in front of you when driving through bright and dark sections. No wonder the reflections are amazingly bad. Chevy really engineered this? That is just crazy.

^ it's not just GM... my 2012 Prius and 2012 PIP both had very bad dashboard reflective properties.... even worse than the Bolt IMO.
These long sweeping dashboards with low angle windshields have issues, they really need to use non-reflective/flat coatings on the dash.

Jetta.... have you tried polarized sunglasses?
I use a pair when boating and they help tremendously in cutting down reflections off the water, etc.

Too bad more shops out there don't offer it as a standard new car service just as much as they do with paint protection, window tinting, etc. If dealers start recognizing this and contracting it out to specialists that would go a long way for everyone.

Polarized sunglasses work as you suggest. As does just putting a black art paper sheet over the dash. At some point there will be third party dash pads available. So it is not the end of the world, just an irritation after spending 50 k$ on a car. Interesting that also is is problem on some Prius's and whatever a PIP is.

PIP = Plug In Prius.
Sorry, I'm so used to abbreviating it I just do it automatically.

Both versions of the Gen III Prius used some kind or organic plastic for the dash, but it was very hard and quite reflective. They did try to reduce reflections by embedding a swirl pattern on the surface of the plastic... but it was ineffective.

There were lots of complaints on the Prius Chat forums back when the Gen III Prius (2009-2015) was introduced regarding dashboard reflections... and no good solutions other than wearing polarized sunglasses.

Lol, couldn't help but laugh at the glasses bit. Spend so much on developing an EV and Chevy couldn't figure out how not to blind the drivers.

That doesn't tell you that there is a particular reflective coating, though. Glass reflects some light all on its own, the LEDs may simply be bright enough to be obvious in the reflection from untreated glass.

For those of you who do not know, the windshield has a reflective coating on the windshield for
the collision avoidance systems red alert lamp on the dash. IDK if they're all coated or not :nerd:

I'm taking Drdiesel at his word as he appears to work in a GM service department and have access to technical data on our cars. If the car has the HUD dash LEDs for the collision warning and braking system, then it is logical to assume that car would have the selective coating.

I was comparing the reflection in my Bolt to an adjacent car in the parking lot and it qualitatively this test seems to support the reflective coating theory. I am going to figure out how to confirm it experimentally, but it is so reflective it is hard to believe that it is just the angle and color of the dash. So if that coating could be removed at less cost than installing a new dark colored dash (2500) as was done by an earlier poster on this thread, that might be worth it. The LED is plenty bright to show up even without the coating and the reflection is more dangerous than the safety achieved with the LED avoidance system.:nerd:

Reviewed the subject on the web and these reflective coatings are very common for HUD's in cars. I wonder if Chevrolet or GM would tell us for sure? The next question is if the coating is on the inside surface (most likely) or buried in the windshield. I found that there are coatings that can be applied to get this effect, but they can be scratched. The research continues.

Maybe the thing to do is visit the Chevy parts department and see if there are two different part numbers for the windshield. If there are, then you may be able to get the windshield without the coating and install it for way less than $2500.

Great suggestion. I was thinking along similar lines. Also started looking at the physics of reflective coatings, index of refraction etc. It is quite likely that if they are using a coating to increase the reflectivity of the windshield, it is a coating on the inside surface of the windshield. This is similar to anti reflective coatings on lenses. Need to find out more, but that brings up some possibilities.

The 55 dollar solution was to by a dash cover from DASH Care. It is not a good looking as the dash where the owner paid $2500 to have the dash replaced, but much better than my black art paper cut out that used the first four months. I have attached a photo. The good news is that with this new dash cover there is no reflection. I still think Chevrolet screwed up.
