Why would my 2020 GWM Steed be dropping tyre pressure monitoring sensors?

The failure to load the sensors is probably a centralised computer problem, since it’s more than one sensor (it would be an amazing coincidence if three sensors died at once). Either the Bluetooth connection is iffy, or there’s a software problem with reading what the sensors are saying.

I’m unsure how Great Wall can call the tyre-pressure sensor monitoring system a consumable. Yes, things like brake pads, tyres and batteries are considered consumables and not covered by a new-car warranty, but the tyre pressure monitoring system should last the life of the vehicle and is an important safety feature. I’d be ignoring the dealer and talking directly to GWM’s Australian customer service department and asking the tough questions. Australian consumer law is pretty clear on matter such as this one.
