Screen brightness stuck on max

Anyone experienced this before with their recharge? Quite often on cloudy days or early in the morning, the screen would be stuck on max brightness and not able to be adjusted via the slider in the settings menu.

If I cover the light sensor in the center of the dash right by the glass (or go into a tunnel/dark area), it still dims the display automatically. But as soon as it's back out in the open (where it's not that bright) it's stuck on max once again.

(MY23, so no physical slider)

Yep - no change. I noticed this actually like a month or two into ownership, even started logging this in a calendar with when it happened/troubleshooting.

Eventually took it for service so I had it on the record, nothing corrected but will definitely be mentioning it on my next visit.

That sounds horrible. Mine occasionally surges as it should going under a bridge but having it stuck bright would be terrible.

I hope they can fix the sensor? (Though it sounds like it does sense) or find another fix.

I also have this issue on my Volvo V90 MY24, I can argue that this is very annoying. I encounter this issue each morning when the sun's come up. Suddenly, the screen brightness changes from the minimum (which I have configured) to the maximum brightness in one step. This morning, for example, when the sun was visible on sunrise at 8:20 am (I live in Belgium) in other cases when the sun is not visible and it's quite dark outside I have this a bit later around 8:35 am. I resolved this temporary by putting a letter on the light sensor, which is in the middle of the dashboard above speaker (I have harman kardon). But I'd not expect this for a car of this budget...

I really hope this will be fixed in a future software update...

@SeattleCat I'm working as software embedded engineer and I can only imagine/hope that this is a software issue. It could be a hardware issue if the hardware design is poor, something that can't be ruled out. I hope the threshold to go to max brightness mode is a software constant 'goto max brightness if sensor.lux.value >= CONSTANT.THRESHOLD' but I agree that this could also be an analogue hardware circuit...

I switched from a BMW 530e and technologywise it's a big regression. The quality of the software is really poor imo :-(

Other issues I encounter (I'll not mention them all because the list is really long):

  • Switching from radio station is not visible in the ui, except from the home screen in the main tablet. So in case your navigation is active, you have to press the home button to get this data. Why not mentioning it on the cockpit view? There is space enough... They integrated a big cockpit screen, but they just show nothing...
  • I'm driving a hybrid. When the car is unlocked and the charging cable is inserted (and locked) and I want to leave and thus remove the charging cable, I have these options to unlock the charge cable: A) lock and unlock the entire car; B) press the unlock button on the remote (really stupid if you have keyless entry as I have); C) press the unlock button in the car. Compared with BMW: just open the driver door, the cable is ALWAYS released.
  • Driving date: such as actual consumption both petrol and electrical are not displayed, nor the average electrical consumption. You don't have access to anything of these parameters.
  • Lacks wireless Apple carplay, my 6 year old BMW had wireless carplay
  • Charging timers are only accessible from the mobile app
  • The car is consuming a lot of electricity in idle when a charge cable is plugged in
  • After charging, you could have less charge as before starting. Consider setting a charge timer overnight of 30 minutes at 6 am. The car remains active until the timer starts, and you will have at least 5% less charge as before plugging the cable in (I'm not kidding)
  • 2 buttons on the steering wheel have no function
  • Charging current/speed can't be controlled, in my case it's 16A or nothing.
  • Switching between drive modes (Power, Pure, Hybrid) is only possible from the menu. They removed the drive mode button from the middle console.
  • It's not possible to use the car in 'Pure' mode by default (how many forests of carbon could be saved in the world with this option? I guess a lot)
  • a lot more but it will take me to far

You might ask yourself why I bought a Volvo instead of BMW? Well I couldn't imagine it was that poor, but also I didn't want to drive an SUV and the booth space of non-suv competitors is much more limited as the V90. The V90 is really a nice car if you are looking for a sporty and a spacious car.

Lucky the driving experience is well, but I have no hope the issue above will be resolved in future software releases. This car is in production for almost 8 years...
