I am sorry for you but the 12V battery failing in EVs with a huge high voltage battery slotted just next to it is pretty funny. I know it is relatively common and there are reasons, but c’mon 😆
That’s exactly why I was pissed. Apparently it’s also « just » a regulatory safety feature that the system must detect the 12v before switching to the main battery…
It was not fun being stranded after midnight in a boat ramp until 2am…
And for some reason, manufacturers still use lead acid 12V batteries.
Tesla makes trash, but their 48V standard makes much more sense than 12V systems.
I’ve had serpentine belts fail on 3 old beaters, sure, but in each case I could drive for a while after that at least (enough to get home in two cases, one was too far from home but I got to where I needed to go and then got towed and fixed at friend’s workshop, I already had the belt in the car, just hadn’t changed it yet). But these were all nearly 20 year old cars. And could’ve easily been prevented by me not being too cheap to spend 100 euros on a new belt, tensioner and pulleys - however, each of those happened when I was way too broke to get a lease on a brand new EV, so 100 euros on a belt kit was also an expense I didn’t want without knowing first that I do indeed need it.
Probably. Never happened to me though. I had to call assistance for that battery which is a known issue in EV6. Which also happens to be a 3 or maybe 4 years old car - typically not within a normal failure range.
As a “known issue” all you have to do is put a 12v battery booster in your car for those emergencies. Or put your 12v battery on a trickle charger occasionally.
My old Alfa Romeo Giulia ICE car did this once, luckily while I was at home. The car was a little over year old and overnight somehow flattened the battery. Nothing was left on, no open doors/boot open, just some kind of software glitch.
It was a love story until I got stranded twice at ungodly hours due to the 12v battery failing on my EV6.

ICE cars can and will strand you with mechanical issues just the same.

You bring up an excellent point highlighting why on-the-road repairability is important and cheaper

My Lexus hybrid has the original 12V battery now for 10 years.
New cars are often sold with shitty tires and batteries to lower the purchase cost. 4 years is not unreasonable to replace them on a new car.

That’s called a parasitic drain, typically happens from cheap accessories like phone chargers.
