I just bought a 2019 Suburban RST and since I’ve had it, the TPMS light keeps coming on. I’ve only had the truck for 2 weeks and it has been to the dealership for most of the time I’ve had it. They’ve replaced a sensor and relearned it multiple times. When I get it back it’s good for maybe a day at the longest and light comes back on. Really don’t what to do. I know it doesn’t effect drivability but if you buy a truck from a dealership you would expect for everything to be good. Any ideas on what I should do?

 

get the diagnostic troubles codes and post them here.

 

Doesn't the TPMS on the 2019 tell you which tire is giving the pressure warning? Does the spare also have TPMS sender?

Could pressure be right at the detection level and be affected by outside temperature or by tire warming while driving?

 

Yes. I don’t think the spare has one. It’s been the same tire every time. It’s just stops reading completely. I’ve checked the air pressure and everything is good. They have put new sensors and relearned it several times but nothing has changed. It’s actually at the GM dealership again today for this.
