2021 Nissan Altima UNKNOWN OR OTHER

Back up camera display distorted

When it rains I cannot see using the backup camera at all. Car also gives false alerts when backing up when raining or after rain.

My car completely malfunctioned, the first time my car only had 2,000 miles on it. I was sitting at a red light on a busy Atlanta Rd. The vehicle went completely dead, I mean I could not even turn on the emergency flashers- " nothing worked" Dead car! I could not go anywhere for about 2 minutes. People honking and getting aggressive in traffic started up in about 2 minutes or so. I stopped in told the service people about it, at the dealership I purchased my car. The service men said it is nothing, it happened to me. They told It would be OK. Now, 2 years later. My car is still under full warranty it had 10,000 miles on it. The same exact thing happened again, in traffic. I told Nissan dealership when I got my oil changed. Told them what happened again. OH you would have a long wait, we are completely booked up in our Diagnostic Dept. They also quoted me a price that was a few hundred for the diagnostic test. I replied to them, My car is still under full warranty. They blew me off again. "saying the vehicle has to be having the problem, for diagnostic to pick up on it. lol Yes, I look like stupid blonde who knows nothing about cars. Thank you
