Owners/service Manual problems of the 2018 Nissan Altima

Since I purchased this 2018 Altima (I had previously driven a 2016 Altima without aeb), I have gotten false positives from the front sensor, stopping my car at random times in clear day light traffic, on dry pavement, with no leaves or other road debris. Front sensor has continuously reported the "front sensor not available" alert multiple times in my cars short lifetime, followed by the crash icon at random times of the days, and all speeds including in the stopped position. The sensor goes out regardless or whether there are other vehicles around. I reported these issues beginningin October 2018 (the same month I purhcased my car). No Nissan vehicle should be equipped with the technology where driver's had no clue when the vehicles will come to a halt and lock without warning. This commonly happens when there are cars around me and there is a change in speed (anticipated or nto), which is common in la. My front sensor has malfunctioned several times and engaged the brakes, several times while driving on the freeway at 50mph. My car also seems to lug at times when I brake from a distance and normally which concerns me. I have reported this issues to technicians and had the brakes checked with no problems found so I have had no choice but to wait for the issues with my brakes and car to compile. The owner's manual admits aeb systems do "not function in all driving, traffic, weather, and road conditions" but the manual leaves out the part about how the systems can cause vehicles to suddenly stop even when no objects are in the driving lane. I originally reported this issue to steve yaeger on October 19, 2018--the same month I purchased the vehicle. Have brought in my vehicle into to Nissan various times in the first 3 months but technicians always told me there is nothing they can do and just shake off my concerns/try to give explanations.
