Lexus LC TPMS Fault

I've got a 2021 Lexus LC hybrid showing a TPMS fault at 136543 km. Symptoms are 'Tire pressure too low' warnings, an error message on the speedometer, and a stored error code. Suspect the sensor battery. Anyone else seen this?

A 2021 Lexus LC hybrid displayed a TPMS fault at 136,543 km, with warnings of low tire pressure and an error message. The issue was suspected to be due to dead sensor batteries, as all four tires showed the warning simultaneously despite having correct pressure. After taking the car to a shop, it was confirmed that the sensor batteries were dead, and replacing them resolved the issue.

Did this summary help you solve your problem?

Interesting. I have an LC as well, though I can't remember what year mine is, and had similar issues. Kept getting low tire pressure alerts even after inflating the tires. Was it happening on just one tire, or all of them?

It's happening on all four tires simultaneously. I've checked with a pressure gauge and the pressure is fine. Could be a faulty receiver?

Hmm, all four at once sounds like more than just coincidence. I had the same thing, and it turned out to be the TPMS sensors themselves. Given the mileage on yours, the batteries are probably dying. I'd suggest taking it to a shop; they can diagnose it properly.

Thanks for the insight. Took it to the shop as you suggested. Turns out the sensor batteries were indeed dead. Cost me 280€ to replace them. Issue resolved.
