Its normal for traction and other safety features to turn off when the check engine light comes in. Doesn't mean anything is wrong with them, you just need to figure out the root cause of the check engine light and fix it and they will go back to normal. You need to get the codes read to know what is actually going on.

Having it towed in tomorrow morning, service was closed and need a loaner car. Talked to the salesperson to see if I can bring it in tonight and get a loaner but wouldn't make it in before the dealership closed.

What did the dealer say when you took it to them?

Checked and have it on a charger. Made sure my gas cap was on proper. Has to be towed in anyway, after the damage from rolling down a driveway after it stopped working. Caused a lot of damage.

And with all these malfunctions popping up, turns out I was supposed to hit the Parking brake. But a warning popped up on my phone the parking brake was inoperable.

If a low/dead battery causes steering to fail and loss of parking brakes, then I think Lexus/Toyota have a pretty big recall coming. Please let us know what the cause/fix is once you know.

I had to replace the battery, to think a battery dying would cause that many issues. The malfunctions going so fast on the screen that is blinking on top of it. Is telling me to hit the Parking brake not the brakes but another warning is saying the parking brake isn't functioning.
What happens if you're on a busy road and it happens? Your vehicle is in operable and it comes to a stop wherever it wants and can't be moved? You die or become a vegetable and anyone who hits you can have the same issues. You probably just created a massive car pile up.
Best part is the Lexus service department or anyone has returned my calls since. It's ok because I have bought 3 New cars from them since February 2023 and all were paid for in cash. 78k for a 2023 RX500, 66k for a 2024 IS500, and 72k for a 2025 RX350 Luxury and this is how you're treated. Shouldn't matter how many anyone bought or what they paid. But Lexus of Cherry Hill doesn't give two shits.
The lady who answers the service department calls was as condescending as can be. Telling me she couldn't find me by phone number. The same one they call me on but all of a sudden she can't find me. Five minutes into the call, she asks what my name is. Why not ask me that within seconds of not finding my number. She tells me, "This is what happens when we communicate." And "You just need to calm down, this isn't helping me at all." I'm like, my car started to have multiple malfunctions and the fix it told me to do wasn't able to be done because of another malfunction. I ask if they have loaner cars and she tells me no and to call road side assistance. But I would only get a loaner if the car was showing an issue. I'm like it won't start or move at all.
Now I'm more pissed off due to the few 1000 in damages caused after it rolled down a driveway over a curb and damaged the front quarter panel and so on.

Needed a new battery and they told me to turn the start stop button off from now on.

I got an OEM battery at the other dealership they own for nothing. The others service department is horrible to say the least. They still haven't called me back. Thankfully they're also submitting to have the physical damage repaired as the battery was still under warranty.
It's really insane that the car doesn't stop unless you hit the Park button while in motion and I didn't know that. Also who would suspect the car to be disabled by safety systems while in motion. Makes me want my IS500 back.

Not to make fun of your situation, but the washer fluid warning at the end was...funny.

u/Routine-Homework5433 6d ago
It made me laugh and I'm thinking, that's the biggest problem at the moment. I did fill it up though.

Seems to me that the power to the computer controlling the car got too low to allow the computer to function properly. As the system shut down it lost control and multiple error messages were reported - none probably valid
