They’ve had multiple non-software recalls

I wonder how they compare to the rest of the auto manufacturers, in this regard.

Here's some data: https://datahub.transportation.gov/stories/s/NHTSA-Recalls-b...

If you're looking at the pie chart, Tesla is not shown, but has had 9 in whatever time period and selection criteria is used.

Most recalls in 2024: Chrysler (72), Ford (67), BMW (36), GM (34), Hyundai (25), Mercedes-Benz (28)

Least: Tesla (16), Mazda (6), Rivian (8), Nissan (18), Toyota (16), Porsche (13)

Another way to look at it is number of people impacted, which changes the "leaderboard". In order of most people to least: Tesla, Chrysler, Ford, Honda, GM, BMW, Kia, Toyota,.... Porsche. Obviously, conflating factor is popularity of brand.

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

According to the NHTSA, Ford has had 126 recalls this year and the next most is Chrysler with 40. Tesla has 9. https://datahub.transportation.gov/stories/s/NHTSA-Recalls-b...

Is this even a fair comparison when Ford and Chrysler offer a lot more models than Tesla does?

What happens in the edge case of losing HV during heavy braking on the freeway? Does the brake booster still function independently of the HV system, or is the driver going to have to push the pedal a lot harder?

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 booster system, to boost the breaks. Much better off just using the extra electric motor to directly boost breaks, without the whole vacuum system as a middle man.

Early EVs use vacuum break boosters, but only because they were the only economical solution, given there was little demand for electric break booster systems. After all a vacuum system is cheaper, if you have a free “vacuum source”. But for last decade or so there’s been enough EVs manufactured that electric break booster systems are now more economical for EVs.

To answer GP question, the an electric break booster system is almost certainly powered off the low voltage (12V) accessory system, not the high voltage system. So a high voltage disconnect won’t prevent the break booster from working, assuming the LV battery is working correctly.

Yeah Tesla is around 4% US marketshare, the largest three players are up to 17%

"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."

It’s not. For example, Saab has had 0 recalls.

And Tesla have basically two models, that's probably why Ford have more recalls but less affected people.

Nothing immediately - Teslas have a both a High Voltage system for the traction battery and a Low Voltage system powered by a separate 12-15V battery. The HV system keeps the LV system charged and most critical safety related functions run on the 12V system. The booster, ABS/ESP, airbags, and steering assist are all designed to remain functional long enough for a controlled stop after an HV disconnection.

You obviously wouldn't be able to speed up again, which depending on the situation, would be where the danger lies.
