2020 CX-5 Problem with EU adaptive led headlights after update

S

Stoyan

Hello everyone. I am facing an issue after I performed an update to the system. Little information and background:

I have a 2020 CX-5 Mazda, with a 7-inch infotainment system and matrix-led headlights, and I am from Europe. My vehicle was with 70.00.335 EU N and like many folks I requested the latest one. I got the file and successfully performed the update to the EU_74.00.324A. Did a factory reset after the update and I can say that it is a lot more responsive than it was before. However, one thing is not working as expected and it happened after the update - the Adaptive Led Headlights function does not turn off individual LEDs when I am driving on high beams anymore and what it does now is just switch to low beams instead of turning LEDs where the other vehicles are.

I have Adaptive LED headlights enabled, the camera is clean. I did another factory reset and still the vehicle does not want to turn off individual LEDs anymore.

Does anyone has experienced this, does anyone have any suggestions on how I can make this work again?

We don't have matrix led in US so not much details on that feature. May be ask local dealer? Assuming this was the right firmware, local dealers in EU would have full details and access to Mazda updates.
 
Understood. Still, I had to try and if someone has some knowledge, please share your thoughts I will appreciate that.
 
Yes, I read all this info in my manual as well. I think it is not operating normally because I am testing it on the same road and in the conditions in which it worked. It just suddenly stopped doing that. Thank you for posting that.
 
I have an update. After another unsuccessful test on the same conditions, I disconnected the negative terminal of the battery for about 10 minutes. The very same night I went out again on the same road, same hour, same weather conditions and settings and it was and still is working as it was before - the vehicle operates on high beams with turning off only individual LEDs where other vehicles are detected. I am not sure what is the connection here but I think this helped the system to start working again as expected.

Thanks to everyone here!
