2022 Nissan Sentra FORWARD COLLISION AVOIDANCE

The car applied automatic emergency braking for no reason. The speed at the time was about 20-25mph. This is around the fourth time this has happened since purchasing the vehicle about 10 months ago.

the pre collision system light kept turning on and off. Also alerting of a malfunction that the system was not working. this happened around sep 7 2022. I took the car to a nissan dealership on sep 16 2022 and inspected. they found out that there was a problem with the system and according to them it was fix. I just want to bring this to your attention because doing some research some nissan owners are having the same problem. In addition, I found out that none of the extended warranties dont cover any electrical system.

While driving the car this morning at about 30 mph, and with no obstructions around, there was a sudden red flasher on the dashboard (a red long bar with a hazard triangle in the middle, three flashes) and I could feel ABS with the car applying emergency brakes automatically. My wife had told me that she also encountered the same problem about two months ago. At that time, we thought it could have been a one off. I bought this vehicle in April 2022. It has done only 1,800 miles. Today's incident was after the 6-monthly (first) service that was done yesterday. I have written to the dealership about this incident today. I am concerned the impact if emergency brake is activated for no reason when driving on the highway. Both my wife and I take turns using the car, and often travel with our two children.
