2 Warnings problem

Failure Date: 01/01/2024

The car has had multiple issues with warning lights and malfunctioning systems. Including : 1. Child locks 2. Every single component of the adas 3. Emergency services being activated at least a few times a month - this is an sos for emergency 911 service. The repeated, continuous and mostly false warning lights are a driving distraction that can easily cause an accident. I have photos of all warning lights coming on in the vehicle. The dealership has repeated stated that they couldn't reproduce the problem even though pictures were provided and the car is still under the original warranty period. The latest attempt to fix the vehicle was to replace the sensors on the front of the vehicle. This solution was only attempted after the 4th report of the problem to the dealership where the car was serviced under the original manufacturers warranty.
