Warnings problems of the 2021 Acura TLX

Problem with all safety feature sensors like adas, lane assistance. Small car icon which always green turned orange, and none of those features working.

On a slightly snowing evening driving on the highway, a warning was displayed indicating "some driver assist systems cannot operate, radar obstructed" and the green icon turned orange. Traveling about 45 mph, I slowed down to get over and the car drastically slowed down without me pressing the brake. After about 10 more minutes of driving the icon turned green again. This has happened on more than one occasion creating a serious safety risk, typically during inclement weather.

I was traveling on the highway (on a very rainy day), when my car's green signal lights and orange engine light began blinking. Immediately, an orange warning sign on the dash read, "some driver assist systems cannot operate, radar obstructed". A few seconds after that occurred, I accelerated to pass a vehicle & as soon as I switched lanes to get over, my car went from speeds of about 85 mph, abruptly down to 15-20 mph. My safety was immediately put at risk as the driver I passed began tailgating me as if my actions were intentional. I attempted repeatedly to speed up, but my car just wouldn't go any faster. Once, I proceeded to get in the right line, I was almost hit by a group of tractor trailers. I called my spouse in a panic, who advised me to get off at the next exit. I followed his advice, pulled over, turned off my car & started it again. The lights turned off & proceeded to get back on the highway. About 3 minutes later, the orange light flashed the same message, "some driver assists. . . . " I immediately called leith Acura & tried explaining what was occurring. Once hanging up with leith, the dash continued to display "call ended" with leith's number flashing every few seconds. The radio also turned off with a "no audio connection for fm radio". Too afraid to accelerate, I drove minimal speed all the way to va. Also afraid to drive back in the same condition, I contacted crown Acura, who set an appointment for June 23, cancelling leith. Service advisor michael informed me that the technicians were unable to duplicate what occurred and placed me in a rental vehicle until my car was assessed and diagnosed. The next day I was informed my vehicle was ready and told the technology was reset. Before & after this, my phone calls are stuck in a limbo state where it will ring through bluetooth, the number will display, but there is no way to pick up the call via phone or car display. "brake" warning also blinks when there are no objects in front of me. *I have videos*.
