My parents Subaru has a constant tire pressure warning because the tire pressure sensors batteries die long before the tires wear out and the cost to get the sensors replaced isn’t worth it. It’s just a useless bullshit feature that makes cars cost more. Check your tires occasionally with pressure checker to make sure they match the psi listed on the label in the doorjam. and if it’s low get them pumped up. I use the free pump outside my local Costco. No membership needed.
