I think your experience is probably very typical for Toronto where it gets quite cold. However, in places with more mild climates, like here in the Pacific NW, I typically get at least 7 years out of my batteries as long as I don't accidentally run them down by leaving the lights on or something.

On the other hand, I felt extremely lucky to get 2 years out of battery when I lived in Phoenix, AZ. Hot and cold are hard on batteries all all chemistry types.

Note that the owner's manual says that the HV battery in the ED can be damaged by temperatures below -13 F (-25 C) for longer than 7 days. It never gets that cold here, but I imagine it does get that cold in Toronto at least sometimes.

Most maintenance parts for most cars are held in local (ish) inventory.
It really makes no sense to keep the rare failure parts everywhere... Think of all the planes that fly all over the world. As long as their system is good, they only need one system and one guy to manage worldwide shipping of parts,,, how many warehouses and how many guys do you think they should use these days? What is the likelihood of getting a part from the opposite side of your contry compared to a trip from Europe?

How many hours/minutes/seconds do you expect?

The battery cell electrolyte can be damaged by extended cold exposure as you list.
I've seen the "battery warming" behavior only once on my car in extreme cold.

I've received parts for my ED from Montvale, NJ (moving to Atlanta in July 2915), Fort Worth, TX and Fontana, CA. Most of my parts have come from Fontana. So clearly, MB has some sort of parts depot in at least these three places. As such, I don't think it is unreasonable to expect the vast majority of parts to be available anywhere in the continental US within 48 hours.

However, I have heard reports of HV battery packs taking 6-8 weeks to arrive at the dealership. That means, the battery is being shipped from Germany by ship, not by air. I think 6-8 weeks is outrageous, but what really matters is what the law says and in most states with lemon laws the dealer has 30 calendar days to fix the car or refund the owners money.

I have also heard of one electric motor failure that took 6-8 weeks to repair.

I agree that there are flights all over the place, but UN DOT and FAA regulations prohibit batteries with more than 12 kg of lithium metal from being transported on commercial aircraft. I'm no expert on batteries used in EV's but given how much testing it took to get small battery packs used in our test gear UN DOT approved, I would be very, very surprised if ANY air carrier would allow an EV battery on-board. As such, the battery in an ED must be transported by ship. That's where the 6-8 weeks comes from. It would be better in my view if there was at least one replacement battery in a depot in the US. Apparently, MB disagrees.

I personally think MB can and should do better. YMMV.

Welcome to SCoA.


If you are still running the original 12V, that would be my SWAG . . .

Not good - what dastardly "event" (usually a CRASH?) might have tripped the fuse?


Unless you are using a M-B Star Diagnostic computer I would not put much faith in a scan of an ED using a generic scan tool???
