PHEV in the title is plug-in hybrid electric vehicle. Different from a pure EV.

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

PHEVs mean that half the time your using your battery to drag around an ICE, the other half the ICE is dragging around a battery.

A very temporary phenomenon in the evolution from ICE to EV.

I think it continues to be under-appreciated how much of a lead Tesla still has in EVs. Even BMW can't make something that is practical. First people said "competition is coming" for about a decade. Now the competition has finally half arrived, but it's still so far behind. Perhaps the closest is BYD, but most BYD drivers would prefer to be driving a Tesla.

Seeing the BYD trucks and other BYD vehicles around where I live in Australia, as well as the other Chinese and Korean brands, they outnumber the Teslas on the street now.

I am affacted by this as well: the rear knuckle uniball bearing was broken after 3 years (Achsschenkel). Many MY here in Europe have this issue, due to bad parts or too hard suspension. But there are two other things that make it a bit unfair for Tesla in comparison to other brands: Often the cars fail official inspections because of rotten breaks - this happens when your drive carefully and the Tesla is using regene…

> that all the other brands have a mandatory inspection from the manufacturer before the cars will be tested by the independent check.

I'm in Europe. Never heard of mandatory inspection before independent checks. How would that even work, or be enforced.

I was quoted $15k in a Tesla service center for a Model 3 battery replacement, with parts and labor.

Wait another year. CATL is destroying the battery market with their new LFP and sodium batteries. Prices are collapsing.

Doesn't sound like a market being "destroyed" to me, it sounds like a market being a market.

> BMW has over-engineered the They have over-engineered the everything , because that is what BMW does. That is what they have been about for the last thirty years.

I won't argue with non EV engineering, but high voltage stuff in an EV is a lot harder problem to make safe in event of a crash and subsequent repair. I come out as a BMW apologist, but Vanja (evclinic Head boss) likes to be overly dramatic. BMW (and almost all other brands) are very afraid that someone will die when repairing/driving/rescuing someone from an EV and they go to great (and expensive) lengths to make su…

Most people need a recommendation for something more current, from people who work on these modern cars daily. The reputation of 25+ year old models can be misleading. Another source of good recommendations could be insurance companies. Cars with low reliability or very expensive fixes probably need more expensive insurance. But I don't know if this data is public or if you can tell apart the reliability from the rep…

> Most people need a recommendation for something more current Bless them, I would rather buy 10 shitboxes than one modern car (and that cost is about the same).

I’d rather not die in a very survivable crash.

I think Nissan is a bit underrated here. I’m leasing an Ariya which has been great (including its charging curve, which is better than much of the competition) and feels more premium than you’d expect from the brand (to the point that the top trim is sometimes referred to as a “baby Infiniti”) with things like dual pane windows to cut down on road noise, as well as a proper heat pump where many still only have resist…

> The 2026 Leaf takes many of the Ariya’s good qualities and one ups them at one of the lowest price points in the industry. Still costs $30k+ USD for base trim. Chinese cars are going for sub-$20k. Few governments want a repeat of the Japanese disruption of US/European car manufacturing, so they were banned before getting the opportunity.

Australia managed to destroy its car industry on its own.

The latest BYD Atto 1 is AUD27K including all on-road costs.

Tesla 3 base model is AUD60K, BYD Seal base model is AUD50K.

You guys are missing out big time by not allowing Chinese cars.

Is it insane? I'm working in this field, and I know how quickly you can come up with such a number if you are BMW and you are deathly afraid that someone will get electrocuted while working on your car, driving it or rescuing someone in a crash. It's a safety and liability issue, where they go to great lengths to actually re-certify a battery after crash. The whole thing is setup so, that even the dummy electricians…

Yes, it is insane. It's a fuse. They must have some stats on how often those things need replacing and it should have been accessible. The customer has - when they buy the car - absolutely no way of knowing what kind of surprises like this there are hidden in the vehicle and besides, it kills the second hand market so you can only trade your vehicle to a BMW dealership where they can absorb those costs for a fraction…

Fuses are not items that should be replaced normally - they are self-destroying emergency protections for the electrical system.

If it is protecting that end users can plug arbitrary loads into, that is one thing - but this doesn’t sound like that?

Why did that fuse blow? Because if that is not addressed, it’s likely to just blow again.

The article and comment aren't debating whether the fuse plays an essential role. There's no reason to make the process of fixing the issue after a minor incident expensive, extremely convoluted, and very prone to error. Making it a very complicated and expensive fix isn't what's saving your rescuer or mechanic from getting electrocuted while working around your car.

You seem to be ignoring the fact that the battery pack status after a crash is essentially unknown. It should go through a thorough and competently conducted safety inspection or it may kill someone in the future. Of course, this doesn't excuse extra red tape tacked into the procedure, but the core idea of an inspection is just unavoidable.

> Of course, this doesn't excuse extra red tape tacked into the procedure

That's exactly it. I understand the importance of safety but reading the list of complaints I just cannot believe that safety is the key driver for the design decisions.

> ISTA’s official iBMUCP replacement procedure is so risky that if you miss one single step — poorly explained within ISTA — the system triggers ANTITHEFT LOCK.

> Meaning: even in an authorised service centre, system can accidentally delete the configuration and end up needing not only a new iBMUCP, but also all new battery modules.

> BMW refuses to provide training access for ISTA usage

Everything about this screams greed driven over-engineering. Since when are error prone processes and lack of access to information better for safety?

We live in a world where everyone justifies taking user hostile actions with some variation of "safety". Software and hardware are locked down, backdoored, need manufacturer approval to operate even when original parts are used, etc.

I’d love to see a ~$20k EV too, but it’s gonna be tough to pull that off without China’s cheap labor and materials, at least until EVs start moving at the kind of volumes that traditional ICE and hybrid vehicles sell at.

Nothing to do with cheap labor/materials and everything to do with a very integrated and highly sophisticated and competitive supply chain.
