radio interference

[Lucky94]

I have a 2021 GMC Sierra and am having an issue with the tire pressure sensors.  GM tells me it's my Samsung Galaxy phone causing radio frequency interference - and Samsung tells me there is nothing wrong with my 18 month old phone.  What happens is while driving the "check tire pressure" light comes on and I will see anything from no wheels showing pressure to 1, 2 or 3 showing.  Sometimes for 4-6 days I get no wheels showing pressure, then back to 1, 2 or 3 and sometimes all 4 showing.  I have talked with GM several times about this, the dealer has had it in the shop several times over the past year and still find nothing.  Any ideas or thoughts on this ?

time to start climbing the ladder at the dealer. the phone thing is just an excuse. in Massachusetts they get 3 chances to fix a problem under warrantee and if they fail they have to take the vehicle back and refund your money. Called the lemon law.
