It’s not a fuse. It’s a fuse plus guarantee plus liability.

> It’s a fuse plus guarantee plus liability.

This is BMW we're talking about. Their guarantees are worth absolutely nothing if my experience is anything to go by and them accepting liability is not something you should have to pay 4K for if other brands can do the same thing under $100.

  • They'll refuse warranty on the XDrive if you don't use approved brand and model of tyres so... my bet is on them wanting to extort all the precious money they can from their poor customers

    • They'll refuse warranty if the difference between thread is too much between front and back as that causes wear of the clutches. Just like you should have the same tire on the same axle.

      Or if the tires are not the right size, especially in staggered setups.

      If you come from a car that is FWD with AWD capabilities, it doesn't matter as much.

      But BMW (at least the ones with the engine mounted longitudinally) which have xDrive are permanent AWD.

  • I'm sure it depends on market, but I also know 100% that if they will certify the battery as safe, and then you get electrocuted when entering your car because the battery was not safe - they will be on the hook, in all developed markets. No one else, that cares about people safety, do the same thing for under $100. Even Tesla, that almost completely disregards any safety - be it "Full Self Driving" or "let's just change this, without checking if the battery is actually safe", does not do it under $100.

If that was the issue you wouldn't be allowed to change your wheels on the side of the road. They'd be locked down to the car and require a complex software procedure to guarantee they were swapped correctly and won't endanger lives.

This is a professional shop raising the issues. They are liable for how the repair is done. BMW is just liable to lose money if people can easily fix their car at some other, cheaper, professional garage.

  • Yes, as changing a tire is completely the same tool-and-knowledge level than repairing a EV Battery.

    If you would see how EV Clinic "repairs" Tesla batteries, you would not say they have any concern for liability.

      I think you are intentionally misrepresenting this and moving the goalposts to make your point. GP blamed safety and liability for the way the process looks like, not the complexity of the task. When it comes to safety you bet that an improperly installed or inspected wheel or tire can be dangerous.

      A short internet search tells me [1][2] that some sort of tire malfunction causes tens of thousands of accidents and kills hundreds of people every year in the US alone. That doesn't include wheel malfunctions (e.g. wheel coming off). Yet this isn't locked behind some manufacturer approval and proprietary tools.

      How BMW chose to approach this is profit driven. The old money printing machine from ICE maintenance, repairs, and spare parts is slowing down so they come up with new ways of extracting money. Like making the lives harder and more expensive for any non-BMW shop to do repairs. They're not alone in this, other brands do the same.

      > If you would see how EV Clinic "repairs" Tesla batteries, you would not say they have any concern for liability.

      More moving of goalposts mixed with not understanding what liability is, and where it belongs. So you tell me what's Tesla's liability when EV Clinic "repairs" a battery.
