I doubt if you will get any kind of useful reply to your question . I guess it was a question but I did not see a question mark. If this system is activating when it should not then you most likely will need a dealer to look at it and it is possible that you might still be in the warranty period .

It’s a known problem. Go back to the dealer and see what they tell you. [2018 Nissan Altima Service Brakes Problems | CarComplaints.com](https://m.carcomplaints.com/Nissan/Altima/2018/brakes/service_brakes.shtml)
