Lexus RC ABS and Steering Issues

Hey, I've got a 2019 Lexus RC hybrid with about 48k km on it. Lately, the tire pressure low warning keeps popping up. Now the ABS lamp lights up and the steering wheel vibrates like crazy. Seems like the power steering assist is also failing, requiring much more effort. Anyone else run into this?

I had a similar issue with my Lexus RC. I'd check the tire monitoring system and each tire individually for punctures, because that could be the root cause. But if you also have a faulty tire valve, that can cause some nasty issues. Is it only happening with one tire?

Thanks, that's helpful. It seems to be mostly on the front passenger side. What kind of issues did you have specifically with the valve?

With mine, the valve was leaking air intermittently, causing the tire pressure to fluctuate. It eventually triggered all the warning lights you mentioned. Honestly, I'd get it checked at a workshop. They can diagnose the valve and see if there's any other damage.

Appreciate the insight. Took it to the shop, turns out it was a defective valve in the tire. Repair cost me 280€. All good now.
