Basically Tesla Roadsters if left for a long period (About 6 weeks) will fully discharge. However unlike your phone which if the battery just goes flat you can plug in, if the battery in a Tesla Roadster (And possibly other models) goes flat then it is dead. And you will face a $40,000+ (sorry working in dollars that is what the values are given in) bill for replacement of the battery. Whats more Tesla are actively monitoring each car and warn owners about low battery levels which is understandable, however in one such case they actively tracked a Roadster using GPS and sent a team to charge the vehicle due to a "Dangerously low" battery level.

Quite honestly this is disgusting behaviour. The issue wouldn't be so big if Tesla would actually admit there is a problem and cover replacement batteries. However tracking a vehicle with GPS, without it appears consent from the owner, is completely disgusting form, no way in hell should a car company track a privately owned vehicle with GPS unless either warranted by the police or explicitly requested by the owner of said vehicle.
Tesla really need to sort it out.

I'm not sure if I'd be impressed or disgusted at the arrival of a team of technicians trying to prevent imminent and expensive failure of my Volvo.

Yes but I keep the GPS turned off unless I want to use it as a GPS. I can see your point, and sure it saved the owner for a huge bill however it is still not acceptable to track a vehicle without permission, I may be wrong and the owner had told them to monitor the car in which case I retract my point, however it is still wrong monitoring the vehicles unless they have permission. Who knows the sales documents may include a form giving them permission. But the battery issues are major.

If they didn't do that, the owner would be facing a $40,000 bill for a new battery though. I'd be rather grateful if I was him.

(Ignoring the whole problem with a battery that totally dies after not being touched for 6 weeks)

Yes I agree, in the owners shoes you would be grateful, and it was only after failing to contact the owner however it is still not right if they are monitoring the vehicles without permission.

I can just see a group of mechanics frantically trying to get power to the car with extension leads all over the place.

Hmm, not sure I'd be happy about that if I hadn't had prior warning confused If I was aware of the issue I guess it would be different but all the same...

Are they monitoring without permission? The article update makes it seem like its an owner option. Couldn't give a st if they were, though, to be honest. My car has a tracker, and if it were able to automatically alert the AA or whoever that the car was in imminent trouble, forwarding my location, I'd be very grateful.

And it's hardly Tesla's design flaw, lithium ion batteries should not be fully discharged for any length of time; there's no battery powered device that will be able to avoid this sort of damage.

From reading the article it sounds like the Battery is dead as soon as it completely discharged.

If you manage to completely discharge a lithium ion battery, I think it will be severely damaged, so yes, makes sense.

As would be any wet cell lead acid battery found in every car on the road... Of course they aren't 40k to replace though

I'm not sure you are correct there, Everything I've found either says discharge it every [insert amount of charges] to prolong the life or do not allow it to fully discharge as it will affect the length of the batteries' life, however none say it will be severely damaged. Tesla are also partially to blame as they do not adequately warn roadster owners of the dangers, they say "Allowing the battery to discharge can cause severe damage" Not that it will completely destroy the battery and not that it is guaranteed to.

I will admit one of my sources does say charge a LiOn battery to 40% and put it in the fridge to store it.

I'll bet it costs at least 40K to build a fridge big enuff to hold your Tesla!

Hmmm my laptop as do all others, will shut down 99.8% of systems when battery level is low.
Why can't Tesla do similiar?

If such perminently on systems are essential (mileage and ECU Ram) then run them on a second circuit surely...

Very strange.

Where as a BMW diesel system is instant scrap when you put petrol in it but this is not a huge design flaw and rather then help you BMW will also invalidate any warranty on the car.

Where as tesla remote monitor the car and tell you to charge it if you forget and in one circumstance actually found the car and charged it up. For some reason this is worse?

It sounds like just some lame halfarsed attempt to hate electric cars.

As to doing it without the owners consent MMMmmmm considering most Teslas are sold to rich american lawyers and IT geeks do you really think that Tesla are that stupid.

agree
also agree with the other comment, re strange the battery doesnt shut down earlier to protect itself.

I doubt they are constantly monitored for location.

Sure, the battery information may be monitored and GPS data might be sent when battery levels get critical, but not before.

So, they might not be being monitored as extensively as OP suggests.

I am also sure that their small print covers monitoring battery levels.

As for the problem with the battery when fully discharged, if this has been disclosed to customers prior to purchase it is not a critical problem nor disgusting. If it hasn't been discloses, then its a different kettle of fish.
