Tire Valve ABS and Steering Fault

I had a similar experience with my Grandland X. The symptoms you describe – low tire pressure warning with ABS issues and steering problems – sounds like a defective valve in one of the tires. Any visible damage to the tires or rims? Hear an air leak from any specific tire? Check the tire pressure while the car sits to see if you can find a tire with pressure loss.

No visible damage, and I haven't heard any hissing sounds. The tire pressure is consistent across tires when I check them cold. Could you elaborate on the defective valve issue? Did you experience the same symptoms, including the ABS and power steering problems?

Yes, I had the same symptoms, including the ABS and steering issues. Apparently, the faulty valve was causing erratic readings that messed with the car's computer, triggering the ABS light and impacting the power steering. The workshop identified it quickly. I'd recommend taking it in; it's likely the same problem and better to be safe with steering and braking.

I took it to my local mechanic, and you were spot on – it was a defective valve in one of the tires. They replaced it, and everything is back to normal. The final repair bill was 280€. Appreciate the help!
