    FYI, I still like both plug-in hybrids:
    • 49% one
    • 51% the other

    BMW enjoys a higher ratio of EVs in the EV markets than their diesel and ICE cars in the ordinary gas/diesel markets:
    • 24,490 - BMW plugins, ~6.8%
    • 361,307 - total USA plugins

    Does a used i3 REx maintainance cost drop to match the under $20k price tag.

    An AC pump failure costs about $25,000+ because metal shards get blown into the battery coolant lines. This issue has been reported twice since December

    Engine mounts are about $5k

    So yeah BMW parts and labor pricing going on.

    Just got the BMW i3-REx back after, "SAME ISSUE AS LAST VISIT."

    "CHARGING PORT FAULTY ON THE VEHICLE COMPLETED SHORT TEST ON THE VEHICLE AND FOUND NO FAULTS FOR DC FAST CHARGE. DROVE VEHICLE TO NEAREST DC FAST STATION AND FOUND IT COULD NOT COMM. WITH VEHICLE. FOUND A KNOWN GOOD I3 AT THE DEALER AND ROVE TO THE SAME CHARGING STATION. FOUND THE KNOWN GOOD VEHICLE TO CHARGE. COMPLETED PUMA 64662152 AND WAS PROMPTED TO REPLACE THE CHARGING SOCKET ASSEMBLY. CLEARED FAULT MEMORY AND DROVE VEHICLE BACK TO THE DC FAST CHARGER. FOUND IT TO CHARGE AND COMM. WITH THE VEHICLE NOW."

    "PLEASE PAY THIS AMOUNT 0.00"

    I can't think of a car whose maintenance costs drop in relationship to the cost of the purchase. Remember the Metro convertible? People were picking these things up for a grand and then getting sticker shock when they found out a new roof went for $4500. :eek:

    For those curious, search the i3 FB group for motor mount (you need to join it first).

    I found
    Code:
    https://www.facebook.com/groups/BMWi3/permalink/2306265589447289/
    of one guy's motor mount damage on his BEV i3. Damage was $13.2K worth. Another guy had his motor mounts break at least twice. Here was one of them:
    Code:
    https://www.facebook.com/groups/BMWi3/permalink/801727249901138/
    . I don't think it'll be easy for me to find his pics of his receipts for those repairs. Lots of stuff got damaged by the breakage each time.

    This guy had a particularly terrible REx.

    Actually I hang out at: BMW i3 Forum - Index page

    This forum is more oriented to solutions. Facebook has a place but permanence isn't high on the list.

    I am not a fan of Bummer or the i3 Rex, but in fairness, social media is where you will see an inordinate number of people with issues complain. You never hear about all the people who are happy with their i3 without someone accusing them of "drinking the kool-aid" or being a "fanboi."

    questions .... yes good idea back on topic. Bob, how is the i3's traction pack thermally managed - cooling fans? or liquid. I presume - you being the man - that you will know.

    It is liquid cooled with a resistance heater. Sad to say, the cabin is only resistance heated on the REx but heat-pump on the BEV.

    I really like how the Model 3 has all HVAC in a single system. REx coolant does not warn cabin.

    A diagram I saw had the engine coolant loop for the Rex piggy backed on the traction motor's. If the radiator for that is located somewhere in the rear, it would be a hassle pumping a heater core in the front for just the REx.

    & that only makes sense - because when YOU are freezing or roasting - a big ol'
    battery will be likewise.

    Here you go. Look at page 26 and we can go over the details.

    My most recent coding redefines the "panic" button into "preconditioning." Like the "A/C" button on our Prius Prime, it is a one-click solution to make the car much nicer in the winter.

    Thanks - Not only is this modification very useful, it also offers a direct alternative to the "Connected" smartphone app which is subject to BMW's flakey network services.

    So this morning leaving at 5:30 AM, the "drive train malfunction" light comes on. The pop-up says you can continue but need to take the car into the dealer (boat payment due?) Regardless, I run my errand and driving to the fast DC charger, enabled the REx that comes on and it works normally. Huh.

    While on the charger, I plug in the iCar OBD device and fire up BimmerLink:

    Without a timestamp, a list of errors could have been collected over a long period of time. We don't have causality. Otherwise, the car worked normally. It could have been a transient. So my practice is to reset all errors and see if the problem returns.

    The error indicator remained so I put the car on a charger and got breakfast. When I came back, the error indicator was clear. We call that "Cleared while testing."

    The i3 does have a tendency to announce issues which have a way of fading away with time. I've been avoiding BimmerLink, choosing to see no evil. Hoping to get another 18 months of mostly trouble free use before exploring my options.
