The vacuum reservoir of the brake booster in cars with vacuum servo brakes (whether vacuum is generated by the engine or an electric pump is irrelevant) stores enough energy for 3-4 full applications of the brakes.

EV don’t use vacuum break booster systems anymore. There are much better and more efficient fully electric break booster systems out there which make a lot more sense. Vacuum break boosters only make sense for ICE vehicles where you already have an existing air pump (the actual engine) providing free “vacuum”, they don’t make sense in EVs where you need to an extra dedicated motor to produce vacuum, to power a vacuum…

There's speculation that move to unboxed manufacturing process is going to ditch hydraulics altogether (can't easily connect hydraulics in such process) and use electric actuators for brake pads.

There’s a physical mechanical open mechanism for doors.

I wouldn't say its hidden given its right beyond the window switches, I guess those are hidden as well then

Other automakers have recalls all the time too. Why is it that every single Tesla recall becomes national news, but virtually no recalls by other automakers ever do? (I can only think of two exceptions in recent history: Takata airbags and Chevy Bolt batteries.)

What I think is more interesting is that when you dig into a lot of "Tesla Recall!" newsitems, the fix is a over-the-air software update.

Fords recall numbers have skyrocketed in recent years. So Fords real comparison to its previous self, 2015 they had 68. Why isn’t Fords roughly doubling of recalls news?

> Why isn’t Fords roughly doubling of recalls news? Oh, I don't know, maybe because Tesla is bigger than the rest of the entire industry combined? Besides, safety recalls are what matters. I get lots of small qualtiy-related recalls that are so minor I don't even bother getting them done. Meanwhile, Tesla does what it can to avoid quality recalls, because for a while it was a marketing blurb for them.

By units sold per year Tesla is the 15th biggest car company. Ford is 6th. (This is with Hyundai and Kia counted as the same).

By revenue from those sales rather than units, Tesla is 12th. Ford is 6th.

"The recall population includes certain Model Year (“MY”) 2025 Model 3 vehicles manufactured between March 8, 2025, and August 12, 2025, and MY 2026 Model Y vehicles manufactured between March 15, 2025, and August 15, 2025, that are equipped with a battery pack contactor manufactured with InTiCa solenoid." https://electrek.co/2025/10/22/tesla-recalls-recent-model-3-...

I don't know much about battery packs -- what's the significance of this particular quote?

A contactor is a multi-pole switch that is activated by energizing a control coil or solenoid, basically a relay that can handle more current.

You find them in motor starters, you can use them to switch multiple light circuits with a single switch, among other uses.

The contactor is what connects the battery to the motors to provide them with power. If the contactor is bad, power cannot flow from the batteries to the motors and the car cannot be driven. I believe the rest of the electronics are powered from a 12VDC battery, all of that would still work.

According to cars.com, the cybertruck has had 8 safety recalls, while the 2024 Ford F-150 Lightning has had 2.

But how many of those Tesla “recalls” were OTA software updates?

A "recall" means that a safety defect or a failure to meet federal standards has been identified in a vehicle and the manufacturer is required to fix it free.

It is a recall no matter how the manufacture decides to implement the fix. If they can do it OTA, great. That will be more convenient for most owners.

This depends on which seat you're in, which model, and which year. Some models have no emergency release in the backseat for certain years.

Here's a model x, this feels pretty hidden to me: https://youtube.com/shorts/cfPhUY9erLM

This model 3 version has nothing: https://youtube.com/shorts/FWUWm9KaHzE

Here's the model y: https://youtube.com/shorts/FVwuOdMBpfo

I'm aware of at least three different versions of emergency release on the model 3 which vary greatly.

It seemed significant because it tells you which models and years are impacted, what part is the cause and the company that manufactured the part.

I've owned three Audis over the last decade with no recalls Tesla deliberately pushes boundaries and breaks from tradition. That's admirable, but traditional manufacturers have decades of engineering knowledge behind their approaches for good reasons. Push the envelope enough and you'll have more misses and in Tesla's case more recalls

You are making things up out of thin air. These are recalls from JAN 2024- MAR 2025 Ford Motor Company, 94 (7%) Chrysler (FCA US, LLC), 78 (6%) Forest River, Inc., 67 (5%) General Motors, LLC, 41 (3%) BMW of North America, LLC, 39 (3%) Mercedes-Benz USA, LLC, 33 (3%) Hyundai Motor America, 28 (2%) Jaguar Land Rover North America, LLC, 26 (2%) Volkswagen Group of America, Inc., 25 (2%) Daimler Trucks North America, LL…

> You are making things up out of thin air.

Not OP but not really. Recalls are pretty rare in most cars.

I own lots of cars and I've only had two recalls in the last 33 years. One for a Mazda minivan to replace a rear hatch shock (i.e. nothing safety related) and one for a Dodge truck (I don't remember what it was).
