Not sure where these warning lights come from

One day, my car was working perfectly, the next day every single one of these lights are on. Does anybody know what could cause this?

Subaru Eyesight; two stereoscopic cameras and a third camera below them and in between them are Subaru's central safety system - our watchful nanny. Dirt, crack damage, humidity, whiteout conditions, fog obscuring windshield cameras triggers various yellow indicators governed by Eyesight electronics. Benign conditions with automatic reset of alerts can go away on their own in a few blocks of driving or after a few days (longest time for me was a weekend before Eyesight reset). Using wiper/washer or squeegee/washer fluid to keep windshield glass clean from dirt helps. Reverse automatic braking (RAB) radar sensors, lane departure/automated cruise control are disabled until Eyesight resets on its own.

Secondary, more serious problems would be battery, alternator, drive belt issues, Eyesight electronics itself and associated wiring. If Eyesight fails to reset on its own by recognizing and separating weather and dirty windshield effects, dealer service is next under warranty coverage. There are many threads in these forums about Eyesight, recognizing symptoms for remedies as owners, and when to use dealer services.

Eyesight may have reset, turning off all related error alerts and check engine indicator before this reply was posted.

The Check Engine light is ON. Go to a car parts store and get the code read for free. Do NOT clear the code. Have them check the battery for free and get the printout. They can also do an alternator check. If you use A-S-S regularly then it may be the battery. Any battery can fail at any time, that is why there is a Warranty.
Then search the Internet and this Forum for what the code means.
Now that you have a clue, go to your Subaru dealer and let them figure it out. At least you will be pre educated so they can't try to ignore the issue.
Make sure the sensors in the bumper are clean and haven't been damaged.
Report your findings on this Forum for all of use to benefit.

How old is the car?

Don't worry about most of these lights. Usually a single CEL will turn on nearly every single other warning light. Not because the other systems have failed, but to attack the driver's attention and force him to repair the underlying primary issue ASAP.

Check the gas cap, let it sit overnight, if it's still there either pull the CEL code somewhere for free and report back to the forum, or go to the dealer.

I respectfully disagree, although I cannot prove my new Xtrek Sport suffered temporary battery issues as other members have reported on their new '24s. I can state that when I took delivery of my Xtrek 7/23, Eyesight dropped out one late morning drive (for 7-11 coffee) and reset on its own after a few blocks. I was already familiar with Eyesight issues from these forums and guessed morning humidity did it as I immediately turned on ac in defrost mode. In a few blocks, Eyesight reset. Another incident was driving in upstate NY whiteout conditions of a temporary snow squall. In two or three lanes of highway, we could only see the right and left solid white llnes, no lane divider lines at all. Eyesight dropped out, didn't need it since we slowed down and the highway was nearly empty. A soon as we passed thru the snow squall, Eyesight returned. 'She/he' (Eyesight) was telling us "I can't see and I'm disabling electronics and light up the driver's display, hold my breath until........." Worst case was on a Friday, a month or two ago, when E dropped out. It didn't reset the next day and I called Subaru to discuss it. The receptionist acknowledged E issues, calmly stated it can drop out and reset but said appointments were booked for the day (Saturday) and I would have to schedule a visit on Monday. I mentioned having it drop out previously, familiar with it resetting and agreed to call Monday if E doesn't reset. I think it reset the next day, Sunday as I went about errands and didn't realize the yellow alert disappeared on it own. About two days before E reset. Battery is fine with zero issues in a year of ownership. Hopefully, I have one of the batteries that didn't come from the lot(?) of faulty batteries in '24s made in Indiana.

If Eyesight is sensitive to voltages, it may as sensitive as abs in some GM models. A number of GM abs issues were determined battery failures, turning on the abs alert.

Software blips definitely do exist in modern cars, most commonly in the head units ... but regardless, a CEL always needs to be taken seriously. The most likely cause of those lights showing up in a new vehicle is that the gas cap wasn't fully seated the last time you filled up, so I'd start by firmly re-closing the gas cap to see what happens. (It may take a bit for the light to go off after that.)

If that doesn't solve it, since the car is still under warranty, it becomes the dealer's problem, so it's time to make a service appointment. That said, most dealers are not as competent as some folks here would like to believe, so I would also stop at an auto parts store to read the error code so you can do some research beforehand.

This is interesting: Updated Subaru Drained Battery Lawsuit Settlement - What Owners Need To Know
Was not aware Subaru had battery issues.
I never use A-S-S and charge the battery every 3 or 4 days.
If enhanced batteries are really an issue then just buy an X2 Power AGM battery. It will charge just fine. I had AGM batteries in my 2014 Cherokee Trailhawk since it was new and it is designed to charge flooded batteries.
Do this Internet search: "do subaru enhanced batteries fail". Read it and weep.

This IS the reason we drive with our CTW parking lights on...to trick the 'not so smart' alternator to kick on full charging power all the time. Have this also de-pinned on our Frontier. Process of elimination dictates that insufficient charged batteries over the last few years with most manufacturers stems from improper charging parameters on these smart alternators or a parasitic draw from mother ship calling the company all the time/too frequently.

Exactly, which is why I mentioned the agm battery. The factory batteries are moribund to say the least(we've had that over 2 Subarus). If you don't think these cars are prone to electronic "isms", I welcome you to browse through the 200+ factory TSB's on the families MY18. My family member just got a letter from Subaru stating the telemetrics modules are bad and drain the battery. Will they replace it, no. If I had not replaced that garbage battery years ago, my family member would have been stuck multiple times at 80+ years old.

Talked to the Product Specialist at my Subaru Dealership. 2024 Crosstreks do not have any battery issues or other issues that may adversly affect the battery. Of course that is subject to change as our Crosstreks get older and put on a few more miles. If it is determined the OP has a real battery problem then so be it. Knowing the CEL code would be very useful to this discussion. Since Subaru's are 'computers on wheels' I like to get the battery tested anytime there is a problem to 'rule' the battery OUT as contributing to the problem. So far I am not aware of any Recalls or TSBs or Class Action Suits or anything else. I don't drive my Subaru very often since it is not my 'daily driver', so every 3 or 4 days I charge the battery. AGM batteries can tolerate deep discharges more often than flooded batteries without being adversely affected, but you still need to keep them charged.

Guess I am staying with EFB vs AGM.

Respectfully, guys ... I know that a few of you like to hate on the Crosstrek's battery and charging system, and you're certainly free to do that even though I pretty strongly disagree with it. But it is super unlikely that the battery is the culprit here, and it's always good to keep in mind that there's a line between being helpful and spreading FUD. I can almost guarantee that a few years down the road somebody will see this thread, not read it carefully enough, and cite it as evidence that there's an epidemic of Subaru batteries maliciously triggering CELs. Threads like this are how unsubstantiated rumors get started.

Just to be clear, guys ... I left that post because the thread was on its way to turning into yet another battery discussion, while the OP had created a Check Engine Light thread. I'm not trying to refute anybody's individual experiences, but the CEL is much more likely to be triggered by something other than a defective battery, and for the sake of the OP and other readers it's helpful to minimize the topic drift at least for a while.

That said, I appreciated the link @sanghill posted, and I hope the AGM partisans take the time to read it. ;)
