I've had my vehicle for 1 month and on at least 10 different occasions my aeb system has locked my brakes up on me for no reason. Each time I've been driving straight and it's been in my work parking garage when no other vehicles or people are in motion around me. Although I've been lucky so far and it hasn't caused me to be rear ended I still see the potential for that happening if this continues and is not fixed.

Automatic emergency braking (aeb) function failed at a red light. Aeb had been set in a 3-vehicle distance. However, upon arriving at the red light, on a city street, with another vehicle in front of us, Nissan Altima 2019 didn't actually respond to the condition and kick off its aeb system to 1) slow down 2) stop the moving vehicle. This is a driving experience dated on June 01 2019.

The contact rented a 2019 Nissan Altima. While driving 50 mph, the ABS activated on its own and the contact slammed on the brake pedal. The failure occurred several times. The dealer and manufacturer were not contacted. The contact did not know if the vehicle were diagnosed or repaired. The failure mileage was 2,500. The VIN was invalid.

Adaptive cruise control and automatic braking are disabled due to "front radar blocked". this is a brand new vehicle I have had for about two weeks (less than 1,000 miles). After doing some internet research, this appears to be a known issue with Nissan vehicles since 2018. I believe my vehicle was manufactured in late 2018. The issue was first noticed while driving with the cruise control engaged and I kept getting closer to the vehicle ahead of me without my vehicle automatically slowing down (I.e., the car maintained the cruise control set speed.) after manually braking and resetting the cruise control, the cruise control would eventually shut off and the attached message would be displayed. Prior to the issue being observed (approx. First 500 miles driven), the adaptive cruise control and automatic braking worked fine.

I own a 2019 Nissan Altima AWD and have experienced a few problems. The most significant problem is the defective forward collision safety feature. Two times the vehicle has improperly and abruptly applied brakes, the feature is intended to avoid collision, but instead its malfunction is creating road hazards. I contacted Nissan Consumer Affairs and they have evaded me and everytime I call they say you have been assigned a case and someone will call you soon. I attempted to service the vehicle two times this week at two different Nissan dealerships. One turned me away stating it's a known problem and Nissan does not have a fix yet. The second Nissan dealership was in the process of issuing me an alternate vehicle when they received a call from the same folks who won't return my call Nissan Consumer Affairs instructing the dealer not perform any service or a loaner. This is so outrageous, but I actually have it in writing to prove the level of negligence and ill service to force a customer to stay in a vehicle that they don't feel safe in. None the less their failure to do their due diligence. The safety feature malfunctioned on the highway once and the next time on a incline ramp in mall parking garage to a forceful hard stop. I have spoken with 3 general managers and 3 different Consumer Affairs call center reps, but yet no service or call back from Nissan North America. Negligent negligence negligent. Nissan is not what it used to be. Stay far away and tell everyone you know to stay far away. I am the owner of a model year vehicle with full warranty and this is how they are treating me. What would you get?

The intelligent forward collision warning is broken warning lights come on and say it's not working driving on the freeway, when you turn off the car it resets but driving again it shows the warning lights again. Only 6000 miles

Cars aeb would activate with no obstruction on the city road while the vechicle is in motion. Would brake really hard and release. Need help!
