Today, I test drove a used car. I was happy with it. Good mileage. Good price for what it was. Decided to buy it. Got all the paperwork taken care of. Drove it home.
Half way home, the tire pressure gague turned on. The test drive, nothing was amiss. But now the tire pressure gauge is on.
They also told me they’d just replaced the tires. So either they didn’t fill them enough or there’s something wrong with the tires or sensors.
Bleh.
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.

It’s not useless, and it doesn’t increase the cost of a car by that much, either. Like, a couple hundred dollars, tops. Yes, you can very easily manually check the tire pressure, but that’s not the point of these sensors. They’re to give you a live notice when the tire pressure is dropping. If you’re actively driving, you can’t exactly check your tire pressure while you’re cruising along at 65 MPH, but that’s the time you’re most likely to experience a drop in pressure. Having a real-time alert of a potential issue before your tire blows up on the freeway is crucial to road safety.

it’s doorjamb, the b is silent
We had a car which did this when the tires were warm. It didn’t understand how heat works with tire pressure.
Was it raining when you drove it home? Used to have a car (I think '04 or '14 Alero) that was notorious for getting fucky when the wiring harness in the front tire(s) got wet. I don’t remember what warning it set off, but replacing the wires was only a short-term solution because all it took was a good rain for it to get fucked up again.
Same issue. We’re 90% sure it’s the sensors on our car. We just ignore it now. We change the tires for winter half the year anyways so it will be on for half the year at least even if the issue was fixed.
