Actually, I was saying the opposite. A Chinese-designed American-branded Chinese-assembled American platform engineered by a GM subsidiary in Germany that is now owned by a French manufacturer would have less chance of being the same as anything else when compared to, say, an Enclave (Traverse/Acadia/Outlook) or Sierra (Silverado/Savannah/Express) or etc.

It would be nice, but I don't know of anyone who would be able to convince GM to do this, especially with the lawyers watching.

That'* probably the point, an annoying non-deleteable light will get you to . . .
- from the perspective of the safety folks: fix the problem and be safe
- from the perspective of the lawyers: fix the problem not sue GM for making it easy to turn off the warning
- from the perspective of the beancounters: buy the parts to fix the problem

They're all soldered on.

A solder pencil is cheap.

that'* true- but in summer I would have to undo everything since the summer tires have TPMS sensors

At the end I guess it is a question about how difficult it is to modify the ECU'* programme - since there does not seem to be any kind of electronic build in switch

Similar to auto start/stop, which can be electronically turned off by reprogramming the ECU

Seems you have your mind made up. Not sure what you want from us. We cannot program your vehicle through this forum.

We're waaay out there in fantasy land, but I just have to say desoldering then soldering an LED twice a year on the instrument panel display board will eventually damage the board, even if a human can do it. The cluster costs more than a set of four TPMS sensors.

Another alternative: Go to a dealer and see if they will turn TPMS off and on as needed. That will probably be an hour labor each time, so ~$200.00+ per year.

. . . or get a set of TPMS sensors for the winter rims and be done with it.

Would you know by any chance if that is possible ?

I will check definitely check this out. We have couple of dealers around here.- should have thought of this myself

No, I don't know if they can and/or will do this, hence the "see if":

If I were their lawyer, I wouldn't let them without a lot of paperwork.

I checked,

They told me, it is technicaly not possible

Ah, well now we know . . . and we've all learned something.

Thanks for letting us know!
