Possibly if you change the headlamp setting from "auto" to either "off" or "on" this will prevent the auto dimming feature from causing the LCD display to go too dark to read?
Auto Dimming darkens LCD Panels too much
The auto dimming feature makes the LCD display panels far too dark to read. I live in LA and drive in several canyons. While the sun is out, the canyon is shaded and the auto dim feature kicks in. This make viewing the display near impossible. Any hints anyone can offer? I have the display lights as bright as they will go using the rotator switch.

Or try covering the sensor on the dash which is in the middle, close to the bottom of the windshield?Possibly if you change the headlamp setting from "auto" to either "off" or "on" this will prevent the auto dimming feature from causing the LCD display to go too dark to read?
Instrument Panel Lighting "day mode" or "night mode" is controlled/commanded by the BCM (body control module), with ambient light level information being fed to the system by the ambient light sensor, located typically at the top of the dash, near the base of the windshield, as Tx Tom indicated in his post above. Normally there is a significant "delay" time built into the (BCM) software that controls (times) the changeover from one lighting mode to another, to prevent excessive or unnecessary or nuisance lighting mode cycling. Not sure what is happening on the Envision in this particular situation, but it sounds like the lighting mode delay timing is not optimal for those particular conditions.
Dougloftus - when engaged in normal "nighttime" driving (when not negotiating LA-area canyon roads), are you finding that the LCD displays are bright enough, or do they need to be brighter? Is the problem you report occurring at any time of the day, or is it happening only at dusk and dawn?
By the way... are you speaking of only the instrument cluster/D.I.C. display for the issue you report, or are you also including the center stack-mounted Infotainment panel (touchscreen) in your observation?
If this reported issue is confirmed by Buick as being a genuine problem experienced by many, then I would expect Buick to issue a software change/update to address the problem.

Doesn't that mean the lighting mentioned doesn't have its own fuse and works off the the main fuse?
I have noticed the same thing. While driving into an underground garage the panel dimmed to a point where the speedo and radio were so dim they were unreadable. I could not find any settings to adjust this problem and the instrument panel dimmer switch next to the light switch does absolutely nothing (in day mode or night).
Sorry for any delay in replying. I was unexpectedly unavailable for some time.
Obviously the issue is still happening. One of the members asked if the panels were too dim during normal nighttime driving. I don't feel that they are, but the top level of brightness could be brighter in my opinion.
one other member suggested covering the sensor. That only makes the sensor think that it is dark and therefore dims the panels. I have tried the opposite and shined a flashlight on the sensor. This did "trick" it and the panels restored to normal brightness. I have attached two images of the panels showing them in the "dark daytime mode" when obviously at 9:30am it was not dark. I feel that the sensor is 1- facing the wrong direction or 2- needs to be adjusted to compensate for when the vehicle is blocking it.

I've tried that but it does not alter the sensor
See my comments and Rbreeze's comment on the "other" Envision forum...Buickforums.com/envision. There a Buick rep replied, but nothing since from that person since the initial reply.
BREAKING NEWS...on 10/24/16 a service bulletin 16-NA-357 was issued pertaining to software reprogramming/calibration of the BCM (body control module) for '16/'17 Buick Envisions. I had my '16 Envision updated today, took less than an hour, and the NAV/Instruments/Camera seem normal as one goes from light to dark, and dark to light surroundings. So far have only tested this in/out of the garage on a sunny day, so will need to see how the lighting adjusts during dawn and dusk situations. But what a vast improvement!
That's great news! Thanks for posting this, Tom.BREAKING NEWS...on 10/24/16 a service bulletin 16-NA-357 was issued pertaining to software reprogramming/calibration of the BCM (body control module) for '16/'17 Buick Envisions.

I've made an appointment with my local GM dealer to have the reprogramming carried out, on Nov. 7th. I'm glad there's finally a fix for this - the improperly controlled day/night auto-dimming LCD panels have been a real bother in my '16 Envision - definitely the #1 issue.

same day/nite problem
Just got a 2017 Envision and the same thing. Even on darker cloudy days it dims and you can barley see dash and backup
cam is hard to see. Mentioned to dealership and they know nothing I emailed this into to them.

How can they claim to know nothing if there was a TSB that came out ?!
I hope you plan to try a different dealer as some go right off the book and what they get in the form of a TSB, or the service advisor isn't being as helpful as they could be or for whatever reason under the dealership sun.
Look up reviews of other Buick dealers and hopefully you can find that alternative. Keep us posted.
At least its just this and nothing immobilizing.

dash dim
I showed my Buick service Manager and told him about the notice at this site. He said he would look into it.
he saw how dim it got. We shall see.

Definitely hope they follow up with ya soon, it's the holiday season and a lot of managers and whatnot like to take their vacation time.
you should take this time to analyze the rest of the vehicle and see what else they could into before you finally make a visit. Better to batch whatever you can while you can. Even simple trips to the dealer can take a lot of time.
Low visibility nav screent
I have the same problem with my 2017 Envision which I picked up on Dec 21. Is there a fix? The nav system becomes unusable at dusk and sunrise or when driving in cloudy weather. Screen is almost black.

yes the darkness is unreal. I ask my dealership but no updates yet
Hey guys...there is a fix. Mine is perfect now. Please read Post #10 in this thread on Page 1 for the detail.
