Tesla Maintenance

Brake fluid does deteriorate, it will get more water in it and that will lead to corrosion. It all depends on the factory fluid. The fluid Hyundai used in the i20 2 generations ago would turn green in no time, from water and subsequent corrosion.

There's no way I can advise anyone to go 5 years on fluid, unless that's how long they will keep the car.
I bought my 2023 EV6 GT in Feb 2023, and I monitor all the things. The brake fluid was at <1% water, and perfect in appearance. The dealer still demanded to change it during the 40K mile service yesterday, and I let them because why not. It only cost $120 or something, so whatever.
 
It's worth taking into account that Tesla (Musk himself, really) has a special attitude when it comes to entrenched standards. The same juvenile thinking he uses for other more-public concepts. It's not the customer he prioritises, it's the idea of rebellion, 'no maintenance' included. Tesla's round-cell pack cooling is based on the priority of performance over everything else, and, as well-known, runs coolant through serpentine manifolds around the cells to minimise thermal resistance. There are many cooling tube connections throughout the pack interior, each manufactured at the lowest possible cost. But to be fair, it all appears to work as designed.

But these days EV manufacturers like VW and Hyundai-Kia have recognised that having a single point of failure between coolant and live cell terminals is less than great engineering as it's an obvious weakness that has no gradations in the rare case of failure; there is no warning and it can never end well. Both those manufacturers have now moved the cooling system to outside the pack itself, to the underside and rely on thermal conduction at that flat surface. There is a loss of charge-rate performance as expected but there is also a much-improved safety margin that these relatively-conservative companies quietly put in the bank.

My 2018 Kona also has this single point of failure 'feature' and it's always in the back of my mind. It was manufactured before the Kona battery fire fiasco that was eventually blamed squarely on an internal cell design defect. During that time however, without understanding the cause, they changed the conventional coolant in production to a special "low conductivity" type that has turned out to be another fiasco. The original formulation developed crystals, plugging up the pipework. If that wasn't bad enough, where those crystals formed they corrode the aluminium pipework. I'll just add that the internal battery cooling panels are also made of aluminium. I don't even want to think what the long-term risk is.

So, why not change the coolant and use a conventional type? Traditional anti-corrosive characteristics apply and those will be refreshed. The same applies to brake fluid. Just apply common sense.
No there isn't. I have a 2023 EV6 GT, and and its eGMP siblings are some of the only EV's that can actually do extended track time all-out. Further, it charges quicker both peak and total time than Tesla. It stays a TON cooler, as well, monitoring battery temps. Much better system.
 
This thread makes me thankful I got a more mature platform for my EV.

lol, I have seen enough facebook posts with tires worn to shreds on the back of Teslas due to horrible suspension geometry to look at this claim VERY skeptically.
Facebook? Then it must be true! J/K...

I can guarantee most of it is from driving too hard. Every independent suspension RWD/AWD car I've owned driven hard will shred the inside of the rear tires. Same thing said about the MYP and how mine are wearing with mostly highway miles. Torque is the issue combined with a heavy foot.

Its because the cars (some) are not perfectly assembled. So you get absurd wear patterns. Some of the guys on the Tesla forums are seeing over 3* negative camber in new Teslas right off the lot, so its not structure damage.
 
Assuming that Tesla's coolant loop is like the hybrid Toyota's. I would think that it can probably live up to 15 years as it has no combustion byproduct. If Tesla say forever I would just leave it alone for 15 years and then see what happen to the rest of the world doing by then.

Brake fluid, etc I would just follow typical things out there. It is not like it is a lot of money and I'm not convinced Tesla discovered something that other regular car companies don't already know outside of battery and electric motor.

My gut instinct tells me someone else would have found problems if Tesla did something wrong, and other companies would have copied form Tesla if Tesla did something they didn't know or do already too.

Fluid is fluid, the coolant is a precaution every 120K miles or 10 years in an HmG product, and brake fluid is treated like normal vehicle fluid, because while water contamination is less of a performance issue, it can still cause corrosion, and the fluid is the same as any other, it absorbs water.

So gasoline and diesel cooling systems have combustion byproducts? LOL

In theory no gasket is perfectly sealing and small amount of gas will leak through over the 10 years of life.

I am quoting what I read from my owners manual: 10 years for engine coolant, 15 years for electric motor coolant system. You don't think Toyota know what they are doing?

No. Toyota is coasting on their 90s reputation. Nothing they've done recently has been awesome.

If that is the case how does this fit in?

With a complete flush and fill, PEAK guarantees this coolant will provide service life protection of up to 400,000 miles or 15 years*.

With modern head gaskets there should be no weeping or leaking of head gaskets unless there is a design or manufacturing issue or some other mitigating factor like high boost. It sounds to me like Toyota is covering their backsides for potential future weeping issues.
When you read things like this it sure seems that way.

The 2ZR-FE engines are notorious for blowing head gaskets around the 130-150k miles range. This is due to the cylinders being very close together, often called Siamese

Sure. However everyone else got worse and the entire industry's reliability peaked at the 90s.

So I guess coasting from the 90s is not such a bad thing?

I think you have a point. I'd go further than the 90's. Regardless they are still more reliable than most American and German makes.

Hey, aren't we supposed to be bashing Tesla here? ;)
 
It is hard to bash Tesla about declining quality when the company never had any in the first place. LOL
They've actually graduated to using automotive grade parts, and by all accounts their panel misalignment and structural leaks have been reduced.

Ummm....no?
Porsche and BMW are now absurdly reliable. The -58 series engine is so good Toyota begged bmw for it for their cars since they cant built a sports car engine as well, for example.
