I hate all these automatic sensors in new cars. I don't usually buy new cars, I get ones that are a few years used. Almost all of them have a light on the dash for a "tire error" because the stupid sensor has died and no one in their right mind wants to spend $300 to replace a thing that tells you your tire pressure is low. Plus, the things die in a few years anyway.

I just do the Homer Simpson solution and put a bit of black tape over the tire error light.

$300? A TPS sensor replacement should cost like $75 including the sensor itself.

I've wondered this for a while and this seems like a good time to ask: Do electric cars use motor oil in the same way as an internal combustion vehicle? Like do you need to get oil changes in an all electric the same way and have a need for a dipstick?

About $300 is what the mechanics in the area usually charge. The dealership is more.

Nope. The only fluid I worry about in my EV is windshield wiper fluid.

$70 at Discount Tire.

Each?!?!

Fuck that. I'll pay $300 for the set and let them do the work for me. LOL

No brake calipers or power steering onboard?

Yeah, $70 for one sensor installed is pretty cheap. Is your $300 number for all 4? Because that's more expensive than Discount Tire's price...

Hmm do brake calipers age? You’re not really using your brakes during normal driving.

Power steering and other hydraulics would need changing eventually.

Brake fluid is hygroscopic and will accumulate water over time despite being in a nominally sealed system. Water in solution with brake fluid noticeably lowers the boiling point which leads to issues under repeated braking (e.g. down long steep hills) as the fluid boiling means you lose braking capacity in that circuit.

You should ideally be changing the brake fluid every few years (2-3 being the typical recommendation) and that applies even if the brakes are used less often.

You can use DOT 5.1 to significantly increase that wet boiling point, but it's expensive for normal car use. I usually use it in my motorcycle, since I've experienced brake fade on that before, and it's... Not fun.

My wife has a 2016 Honda Odyssey, and having grown up working on cars because my dad was a mechanic, I was shocked to learn that there is no transmission fluid dip stick. It's considered a closed system and never needs to have the fluid changed, allegedly.

Huh? In here you can get DOT5.1 for the same price than DOT4. Roughly 10€ per litre, depending on brand and how big bottle you get.

This is a reactionary response, you're just arguing, slow down a bit.

Do you see a value in a check engine light that tells you something is wrong in between full inspections? This is similar, this is telling you there isn't enough oil and damage is occurring before you get a chance to inspect the dipstick.

It's not planned obsolescence unless they also make it unreasonable to service. We already expect to routinely service engines, and they are already very complex and full of sensors, sure this is adding to the complexity but it's relatively pretty minor.

The argument being made, and I agree with it, is that the benefits of an additional long-serving sensor way outweigh the con of having one additional sensor in your car. You get early warning before damage occurs, you get built in fraud protection when you're changing your oil at a shady chain, you eliminate a direct access port for dirt to contaminate the oil.

Not where I am; DOT 5.1 costs 2-3 times as much as DOT 5 locally.

DOT 4, $.375/oz.

DOT 5.1, $1.42/oz.

It's 3.8x more expensive to buy DOT 5.1 locally.

friend of mine had a ford like this. and it cost more than the car to fix after only 10-15ish years of use. its terrible.

Yeah, that's just how it goes as the engine becomes more complex, leaving a dipstick there is not gonna change that...
