The TPMS on mine (not a Tesla) has gone bad twice now. I'd be in favor of removing them since they serve no real purpose except to go bad, as far as I can tell. I mean, it's fairly obvious when a tire needs more air anyway. The last time I just left it because it's not worth fixing. Although when the car was inspected, they fixed it anyway even though I didn't mention it, and they didn't say anything either (or charge anything).
I’ve never had an issue with mine on my Golf or BMW.
Personally they work very well and alert you to a problem much earlier than a visual check would.
Also running any car (but especially an EV) with incorrect tyre pressure will effect the range.

I like having TPMS. Teslas are low energy BT so they are supposed to last like 10 years.

I added a car tire (run flat) to the rear of my motorcycle (see going darkside). I added and aftermarket TPMS to know if it is low on air.
 
Our first company Tesla - 2022 Model S Long Range is having a wheel tire pressure sensor always on, not going away when driving and we have had it about a month and a half now. Vehicle has about 90,000 KM. Tires have been checked normally and are fine, so it is something wrong with the TPMS. Anyone have this before or know of how to reset or fix this?
You can try changing your tire type (which resets things) to see if it goes away. Do all the tires report a pressure back in the service menu option? I am pretty sure you don't have to enable the full service mode to reset TPMS.

I didn’t phrase my statement correctly so I don’t blame you for misunderstanding it. Reading it I would have misunderstood it. GM isn’t failing as in going bankrupt, at least not anytime soon I hope. They are failing to keep up with technology. If they don’t keep up that could lead to bankruptcy, but I suspect that won’t happen. Yes there’s no reason to change out an entire frame to refresh a car. Once legacy auto catches up and starts using giga castings they will do the same thing as Tesla. It’s not just Tesla by the way. There are many Chinese electric vehicle manufacturers that are also way ahead in technology. Tesla isn’t ahead because of what they’re doing, but rather the failure of legacy auto to compete.
Honestly, I'm not sold on gigacasting. Especially with what we're seeing in repairability. In certain accidents, it seems like gigacastings are totaling out cars where traditional chassis could be repaired.
I think castings have their places, such as how the strut towers in my Jeep are cast Al. Pretty easy to swap out, and they're more intricate to hold/mate to other parts. As well as more rigid etc.
But if I were to be in a fender bender and the whole front 1/3 of my car was gigacast, the car would be trash.
I'm just not down with that. It would probably influence my purchase, now that I'm more aware of gigacast chassis design.

It’s the future. The fact that your iPhone or android phone doesn’t have a removable battery makes it harder and more expensive to repair. It even might influence a decision if the phone is “totaled”. Anyone could pop off a cover and put a new battery in but having someone install a battery costs significantly more. This doesn’t mean phones are going to keep outdated technology. There are trade-offs with anything. Giga casting allows an extremely safe vehicle keeping costs down. People don’t like to talk about cutting costs, but everyone has a budget. That’s why we’re all not driving around in a million dollar car.

As to influencing your purchase, I don’t think many people are going to look at the method of production. I was going to buy that Ford Ranger, but I realized the strut tower was cast aluminum so now I can’t do it, said no car buyer. I’m not saying someone won’t do this because there’s some nerd out there that’s going to nerd out on how something is made but the average car buyer isn’t looking at that.

They serve a purpose to let you know when your tire pressure is low. This was actually mandated to improve fuel economy.

It’s obvious if it’s flat or really low, but if your tire is supposed to have 35 psi and it’s only has 30 you can’t tell. At least I can’t

From what I have seen, there is no real difference from unibody construction. Most crashes that would bust the casting would also bend up the stamped crumple zone. While those can sometimes be pulled out...they should not be, as they are often unsafe in the next crash. Many of those "repaired" cars have been totaled and are "repaired" poorly. There is an entire industry (at least here in the US) of repairing and reselling cars with salvaged titles.

No thanks.

Munroe Live has done several videos as an old-school Ford engineer debunking the casting concerns.

I just top off regularly anyway, seems better than waiting until a warning light tells you. The only time mine ever came on is when it broke and wouldn't go off.

I can see my actual tire pressure in the UI with the TPMS. I don’t have to wait for a warning light. It’s in the UI to the nearest PSI. Old school TPMS systems worked as you described (or you needed an expensive reader to get the details). My B7 A4 just said a tire was low, not even which one and by how much.

I can even see it in my Tesla app remotely. I’m sure you can’t see a low tire pressure from another state away. Lol. I parked it an hour ago.

It is not old school vs new school, both are current techniques, just different. The correct terms are direct and indirect TPMS. Yes, indirect TPMS does not provide the actual tyres pressure, what it does is utilising the speed sensors in the car and can indicate a measured difference between the wheels. Both methods are perfectly fine at doing what they need to do. One is reusing sensors that are in the car regardless, the other requires sensors inside the tyres with additional radios, pairing, and specific locations on the car. Both can indicate which wheel it is that is out of range.

You don't really have to wait for the warning.
I'm sitting here at home and just checked that my tires are at the Tesla prescribed 2.9 bar (or where 18 hours ago when I parked it)
2.9 being 42 psi according to Google.
My previous car (from 2014) also did the same. Without the app part but still, real time measurements.

I’m guessing you’re older and like me used to doing this. People don’t do this for some reason or another. Maybe it’s because of the warning lights. People used to change their oil every 3000 miles but now wait for a warning message to tell them to do it.


As a few people pointed out some newer cars show you the actual pressure rather than just a low tire warning. This is much more useful. Think of it like checking your tire pressure with the gauge without having to do it. However, I find this confuses some non-car people that don’t understand how temperature affects pressure. “I set my tires at 35 but now the front ones are at 39. I’m not sure what to do.” Sometimes too much information can be a bad thing.

Given how many posts I have seen every winter going, " Why is my tire pressure amber" I don't think it is obvious when a tire is low to a lot of people...... Nor realize PSI will drop when temps get cold.....

Nor do they know the recommended PSI of their current car. They often assume it is just like their last car.

Totally agree. I’ve had a hard time explaining to some people that the correct pressure is on the door frame. I don’t know how many people have insisted to me the pressure is on the tire. It can be difficult to convince a grown man that what he thought his entire life was incorrect 😂

Yes in as good as any car it’s on the B pillar 🤣 Always funny when you get the question and point that out to people. I guess it’s only easy when you know it. Just like how the petrol gauge indicates which side you fill up the car 👍
 
Just charging at the services on the way home. The guy next to me is struggling and hasn’t got a clue it’s easier to download the IONITY app.
Anyway I sorted him out and his Porsche is now charging next to mine.

Yes shame, when I heard some of the stories I knew they weren't going to make it. Not because the product isn't good, but because the company isn't ran correctly. As an example they were spending more on their CEO's travel then they had turnover, and it was paid into the family company. Only one person who earned from this.

Shame such a missed opportunity, when you see that in countries like the Netherlands VANs have to be zero emissions to do business in the big town. It was their job to be aware. Production at Nedcar would have benefitted the company, and especially so with such policy.

Nice startup but run (ruined!?) by inexperience.

here is some more on the history if anyone is interested
 
And for something a little bit different. Amazon is electrifying its delivery fleet across Europe. It ordered more than 200 Mercedes-Benz eActros 600 electric heavy goods vehicles. Specifically for its high-mileage routes within the middle-mile network in the UK and Germany transporting trailers to and from fulfillment centers, sort centers and delivery stations. They also are planning to install 360 kW charging points at key sites.

here in the US they have partnered with Rivian for delivery vans, our neighborhood delivery van is on of those, quite nice and quiet ;)
Have not seen any e-trucks yet here

 
Centuries ago the Catholic Church used to sell indulgences and that may have been a very relevant factor to some quite significant events.

Now it seems that you can achieve the same result for a lot cheaper.
