I was leaving for work, backing out of the driveway, and the brakes just locked up out of no where. I’ve done this multiple times and the brakes have never done this. I tried pulling up and trying again, turning the car off and back on, and backing a different way out of the driveway. It kept locking up on me and nothing was in the way. My husband had to eventually take me to work. The automatic braking system failed. I’m not sure if it is available for inspection upon request. At the time, my safety or anyone else’s safety was not at risk. I just worry about if it happens while I’m driving on the road. That could defiantly not only put me at risk but also other drivers. No the problem has not been reproduced or confirmed by a dealer. It just happened this morning. The vehicle has not been inspected. No warning lamps. It did pop up the car with the 3 blocks in front of it on the screen like I’ve seen before, prior to failure, but not the warning about the automatic braking system.

The vehicle has activated a false aeb on several ocassions since I purchased the vehicle. I immediately took it back to nissan and they stated there were no recalls and the vehicle seemed to have no issues. I've had the vehicle for 5 years and it continues to occur, nearly causing a traffic collision. Twice this year, the vehicle made a complete stop on the hwy and took a minute before I could resume driving.

Car phantom brakes. There are multiple cases of it online where people are complaining when the front emergency brake warning light comes up at times and the car brakes automatically in empty highways. This happens fairly often

I noticed a month ago I was driving and both the rear and front emergency braking lights came on in my dashboard but the car never actually began to brake. Fast forward to today when I was backing in to park my car and the emergency brake engaged and I could not back in. Nothing was around me, I wipe off the sensor and it still would not let me back in. I had to turn off the emergency brake system just to back up my car.

This has been happening multiple times since December 25th, 2023. Presently, it's in the shop for the 6th time. This orange light comes on and then right after the vehicle just stops or slows down. Nothing is in front of or behind me. It's random...happens at night or anytime during the day and it stops itself while driving. It has been taken to the dealership 6 times since December and the problem has not been remedied. It is scary getting into the vehicle every time because I wonder, will it happen today? And what if someone is behind me? That could cause a major accident with injuries.

Front crash warning malfunction on my dash

1. Power steering cuts off while driving. Occurs intermittently -- once every two weeks or so. I am guessing that the intermittent nature of this is why more have not reported it. Warning lights show on dash indicating ABS, etc. but codes disappear when car is turned off and back on. Yes, you can inspect this. We bought a BlueDriver OBDII with an app because we couldn't capture this and the dealer couldn't recreate the problem. I have the records of the codes. We were able to get the vehicle to the dealer while still running and they are fixing it by replacing the ABS computer (at significant cost). 2. Sudden loss of power steering could result in a major accident -- especially in emergency situations, at higher speeds or if the driver was weaker/smaller. My wife drives this car, and it was a major shock when this happened. Fortunately, she was moving less than 30 mph when this happened -- and she was not trying to avoid an accident. 3. The problem has been reconfirmed by Regal Nissan Service at this time. [XXX] See above for description of how hard it was to capture this condition. 4. The component has been deemed unworking. I believe that the dealer is just replacing it, however, vs, in-depth diagnosing at the corporate level. 5. The warning lights come on at the same time the power steering stops. There is absolutely no pre-warning. We have no idea if the ABS system also stops working because conditions were dry, speed was low, no slamming on of brakes -- but I am guessing that the ABS also wouldn't work. That's a guess.
