Was never fond of Corporate America but they have taken nauseating greed to a level that even I didn't think they would.Mechanic friend was telling me about how many models you can't even read your tire pressure with a simple guage any more.Each valve has it's individual sensor in it now and you have your read out on the dash digital readout.That sensor goes bad - 150.00 smackers,that's not covered under the drive train warranty.Many can't afford this heinous goughing.Those cocks don't deserve prosperity

I was losing pressure in a tire in the GTI not long after I bought it.  Once a week I'd have to put air in it, it got annoying.  They found a tiny nail in it, too near the sidewall, so I replaced it.  I would not have noticed its being low pressure without the TPMS.  It looked fine, and I don't routinely check pressure any more, or anything else.

I doubt the car makers added them to make more profit when they break.

2021 Porsche Macan Review, Pricing, and Specs (caranddriver.com)

The car across from us is a black Macan that the wife really likes.  There are very capable vehicles, this probably would be my choice among the breed.

With a refined chassis, strong turbocharged engines, and a comfortable cabin, the 2021 Porsche Macan is dual-purpose package unlike any other vehicle on the road today. It's equally at home tearing it up at a track day as it is running Sunday errands. Performance is impressive, and the Macan's suspension is poise personified: taut while cornering but not so firm that it sacrifices ride comfort on the work commute. It's this flexibility that earned the Macan a place on our 2021 10Best list as well as an Editors' Choice award. All-wheel drive is standard, and buyers can pick from one of three turbocharged engines. Some auto enthusiasts may kvetch about the infiltration of SUVs—and we're guilty of similar complaints—but with the Macan, there are so few compromises that it deserves respect from even the most ardent SUV detractors.

Yeah, those sensors have alerted me to nails/screws that have been picked up in tires several times. Probably wouldn't have noticed until they were REALLY low otherwise.

With the exception of sometimes them starting to trigger when the temps get "cold" in the winter because of the change in air density, I've never had one fail on me that I can recall.

I'm having some issues with the rain-sensing wipers in the Flex, though... Not even sure where to begin with that crap.
