As they point out, the Tesla pyro fuse (at least on a Model S) is a cheap part. However, in some model years it's on top of the pack, which means you have to drop the pack to get to it. And, from memory, it's a 10 year lifespan part. However, on other Model S cars, it's easily accessible from the bottom. I wonder how we can make automakers make more repairable cars. Obviously, right-to-repair and allowing access to d…

“ I wonder how we can make automakers make more repairable cars.” This is what insurance companies are supposed to do if they price things properly.

This is exactly why I’m so uninterested in driving en EV. I usually word it as “I don’t want to drive a computer”, but the reality is that I don’t want to be on the wrong end of the power imbalance that comes from this amount of complexity.

EVs are not complicated. Modern carmakers might make them complicated, and you're well within your right to avoid those, but in general electronic propulsion is pretty simple. The problem is car manufacturing is a very expensive industry that's extremely difficult to disrupt, so incumbents aren't really worried about staying ahead of hungry competitors. Go look at small-scale PEVs - ebikes, scooters, unicycles, etc.…

OP did not say they would not travel on electric trains or unicycles or elevators or electric forklifts or electric container ships. They said they don't want an EV. The things that modern carmakers make complicated.

BYD has the world’s fastest car now. I think they are targeting the market, not a market.

And 9 times out of 10 when BYD is brought up people are talking about their low priced cars like the Dolphin or Seagull, not their halo car.

Sure - you start on a segment. Tesla started at the top of the market and got stuck trying to work down. BYD is starting at the bottom but they are making it pretty clear that’s a choice not a constraint.

I have never owned or wanted a pickup, but now I'm wondering about getting a basic one (if that's still an option.) It is annoying and depressing.

CAFE standards have made that pretty hard. The trucks got bigger to hold more complex engine setups to boost mileage, coinciding with preferences shifting to super crew cabs because buying a new truck is basically the same price as buying a luxury vehicle. I did own a 1994 Dodge ram up until a few years ago, but it needed new brake lines and there was so much rust coming off the frame I honestly wasn't sure I trusted…

Frame damage apart, brake lines (in general, though I haven't worked specifically on a Dodge) are a reasonably straightforward DIY job. Not at all saying you made the wrong decision abandoning that particular car, just encouraging others reading this to evaluate the cost of a brake system replacement more, um... creatively, and least do some research. Basic car repair is an immanently nerdy pastime, and can save one an immense amount of money - especially on that particular era of automobiles, which are typically pretty satisfying to wrench on.

The majority of their cars (Y/3 models) have the penthouse (top) of battery pack super easily accessible from under the back seat, no need to drop a pack. Not to mention Tesla has the best service mode system in their computer of any brand of all time. They also have the best free to owners assembly/disassembly manuals in the service portal https://service.tesla.com/ . They have taken self-service literally to the ne…

+1 for the Tesla service manuals. My wife’s was making a clunk from front suspension. Before my assistant (my kid) had finished taking off the wheel, I found the up-to-date official torque specs on service site. Usually it takes me a while to find torque values and cross check with another source. It was beyond refreshing to see Tesla buck the trend of selling service-manuals-as-a-service.

Service documentation / manufacturer software required for cars I currently wrench:

- Early 20’s: Bookmarked URL to the official online documentation (Tesla). With that said, I haven’t had need beyond checking mechanical connections, flushing brakes, and replacing filters.

- Early 10’s: VM containing a mid-00’s version of windows that runs a cracked copy of the long defunct manufacturer software service manual. Also runs software to interface with car, but simply painful to use. Beginning of era where tasks like replacing the 12v battery require manufacturer software to interface (though simple things still had undocumented secret Contra-like button sequences to do so).

- Early 10’s car: folders of screenshots and pdf exports collected over a decade for various procedures I needed to do. OBD-2 dongle + generic app handled basic things. Not much different than decade prior vehicle.

- Early 00’s: PDF of a seemingly printed-and-scanned copy of a digital version of the service manual. Off by a model year, surprising number of inconsistencies given its German. Computer and K+DCAN connection required for re-coding new parts, flashing, etc. Some fancier OBD-2 scanners could do majority of service related functions (cycle abs, reset airbag light, etc).

- Late 80’s: PDF scans of the dozen+ service books (still trying to luck into a physical copy of the set without paying an absurd sum). Most mechanically complex vehicle I own. No computer necessary, but soldering required.

Teslas are dead simple, to the point where people are putting Tesla anything in virtually anything you can think of - classic cars, random sedans, you name it. There’s also that guy on YouTube who updated the electricals in his original Model S with electricals from a 10 years later Model 3 Highland just by buying spare parts, and it was pretty doable with fairly basic and limited tools/public information. So the com…

> I wonder how we can make automakers make more repairable cars.

New mandatory test suite: Have executives/leading personnel do common repairs and time it. Publish min/max/avg time next to fuel efficiency and safety rating.

Repairability would be top priority overnight.

In principle and EV car should be much simpler than an ICE car. It seems they are adding a lot of extra stuff that's not really necessary.

I think you are referring to BEV cars. The definition of EV includes hybrid and plug-hybrid (which the fine article is about, by the way).

This is true. EVs are much simpler than ICE, and PHEV basically have all the complexity of EV+ICE.

PHEV means a lot of things. Toyota PHEVs with e-CVT are simpler than a normal ICE. VW PHEVs where there’s an electric motor tucked into their DSG gearbox - not so much.

And then the kicker. VW doesn’t allow the dsg with electric motor to be repaired by dealers. If something is wrong it needs to be replaced completely. At the cost of €15k (NL, 2021). The only serviceable thing is the clutch and the mechatronic.

IMHO this is something that should be regulated away as consumer unfriendly and environment unfriendly. (Not to say hostile.)

In the end I got a DSG specialist fix the problem in two hours by replacing two simple components physically. The car then spend an hour retraining the dsg.
