Adaptive Cruise Control problems of the 2018 Nissan Maxima

I purchased this vehicle used a couple of months ago. The automatic emergency braking initiates inappropriately while using icc, it brakes without obstruction. Also, the distance sensor isn't working properly according to the dealer. When I use icc, and sometimes when I am not using it, I get an "unavailable, front radar obstruction" message. The icc stops working when this happens. It happens every single time I drive. The dealer I bought it from (not a Nissan dealer) won't address it. The Nissan dealer I had to pay $160 to diagnose it said it has a faulty distance sensor, which will be repaired if I pay over $1000. I only have $13,000 miles on this vehicle, and it was 11,000 when I bought it. This has a Nissan service bulletin easily found online, a known issue to Nissan which is a safety issue, but it isn't recalled and should be.

In June 2019, while driving my 2018 Nissan Maxima, the vehicle suffered a sudden and violent mechanical failure. Without warning, the steering wheel jerked forcefully to the side, and the vehicle became uncomtrollabel leading to an approx 100-foot spin across a median. ?I have since verified this vehicle was subject to NHTSA recall 19v-807 for an abs actuator leak that shorts the circuit board. This defect caused the crash, which resulted in a traumatic brain injury (tbi) with extremy worsening memory loss 4mm spinal shift (l5-s1). I have comparative mri scans (2015 vs. Post-crash) confirming the injury.
