I get this light occasionally on the 2022 Nissan Sentra, it comes on randomly then dissapears. Does anyone know what it means? Thank you!

That symbol is for the forward collision system. Are you seeing any messages in the instrument cluster at the same time?
No other messages. It comes on randomly and then turns off a few minutes later.
Look it up on the owners manual. It means different things based on the lights behavior.

When mine came on it would be flashing and a message in the ic would accompany it. For me it was saying the camera was too hot to operate.

Staying on solid means a different reason.

That's correct. Flashing is unique, it only means a temporary camera issue (blockage or a hot CCD). When it's solid but comes and goes, it usually means a front radar blockage. That can happen from temporary factors like rain, snow, dirt. If it stays solid then there's a serious code in the ADAS that the system can't resolve.
If flashing were unique, then it would be something that rarely happens, and only to his car. It is not unique, it is simply one of a few failure indicators. My turn signals flash, and there is nothing unique about it...
Duh. A flashing crash lamp is unique to temporary cam problems. Nobody said anything about other lamps.

Yes, I have experienced this during a heavy rain, would go off after the rain slowed down
That means the collision avoidance system is disabled (by driver) or otherwise not functioning. I know because I had a '21 Sentra and got into the habit of disabling the system every time I got into the car! I did this because it was malfunctioning and several times applied the brakes when there was no danger. I decided, rather than have the system engage when I'm going 65 MPH or when I'm passing through an intersection, I would just turn it off.

I would tell your dealer ASAP! There are reports of folks getting into accidents because of this issue that should have triggered a recall, IMHO.

Be safe.

When the MIL (malfunction indicator light) comes on, then goes off it indicates that the ECU/OBDII Computer has detected an anomaly in the EVAP Emissions Control System long enough to indicate the problem via the MIL dash light, then after monitoring the sensor that detected the off spec value(s) for a short period of time afterwards and not seeing the initial "off spec" reading anymore, the ECU Computer will turn the MIL (malfunction indicator light) off.
The process will continue until you determine the cause and repair it, or until the problem corrects itself permanently resulting in the MIL turning off and staying off.
As crazy as it sounds, these intermittent MIL dash light senarios, believe it or not are sometimes as simple to fix as tightening the gas cap or a gas cap replacement altogether.
Keep in mind that the MIL dash light only comes on when the computer detects an issue with the EVAP Canister Emissions Control System.
Also, if you ever discover that you have a "bad/leaking" VIAS Solenoid, Swirl Control Solenoid, Fuel Vent-Valve Solenoid, Fuel Shut-Off Solenoid, Fuel Tank/ EVAP Canister Pressure Solenoid, or EVAP Canister Vent Solenoid, you can easily bend the 4 metal tabs back, remove the metal casing, slide it off and replace the two round rubber "O" Rings / Rubber Grommets for pennies and save yourself a lot of $$ by not buying Solenoid Valves that otherwise work perfectly.

Who on earth mentioned the MIL? This discussion is about the FEB/AEB "crash" lamp.

He is likely a bot or spammer. They make long posts that are not related but instead talk about something that a key word in the original post triggers in their algorithms.

I know, but there are also a lot of people who talk just to hear themselves (I won't name any names). That's no more constructive than a bot.

Also, an automotive battery that needs to be replaced can cause your MIL dash light to come on and to go off, as a battery that isn't charging to 12.8 volts or able to maintain 12.8 volts once charged by the alternator to its maximum level of 12.8 volts will fire the spark plugs at an improper voltage, resulting in a "Cylinder One Misfire" DTC (Diagnostic Trouble Code) from the ECU/ OBDII Computer. And lastly, keep in mind that an OBDII Diagnostic Scanning Tool does not tell you what part to go out and buy to fix the issue at hand. Some people might get extremely lucky and fix their vehicle by purchasing the first part thrown at then by their scanning tool, but the other 95% of people repairing their own vehicles will end up just thriw

Apparently the website is misconfigured because the question being posed to me on this site by someone named "sunsmile" states:
"I get this light occasionally on my 2022 Sentra. It comes on randomly then disappears. Does anyone know what it means? Thank you."
So if you hillbillies are talking about lawnmowers, Bills foot fungus, or how weird your kid named Bobby is, then excuse the algorithm bots for getting the informative responses mixed in with your discussion about how the ally where you drink beer and fart on each other needs a couch so you guys can regress in comfort.

What's misconfigured is your browser, because it must not show pictures. The OP's picture clearly shows a crash lamp, not a MIL or anything else.

So we are hillbillies cause we can see that you are posting about stuff unrelated to the subject matter? Lmao at that thought process.

We have been seeing a large amount of posts like yours lately. Posts that key in a word or phrase and talk to that. They are never on topic. This description fits your post to the tee. If you are real then hopefully you will start trying to be on topic moving forward.

How can you TALK on a message board, it is text on a screen; and furthermore more; how do you even HEAR them?
Try looking up the words "colloquial" and "analogous".
Try looking up "literalism". Maybe also "seek help", you seem to have some unresolved anger issues.
SO, I tell you to seek help, and you tell me to? Wow, that's original, do you make sandwiches too?

I am not the one who hears text in a screen...
What is your deal dude? Let it go already.

And I'm not the one who takes "literalism" to ridiculous extremes for no reason other than...
