    Off Road in i3

    The tires are the Achilles Heel of the i3 with many owners experiencing flats and punctures caused by ordinary street debris and potholes. My guess is that driving the i3 off-road with any regularity would not end well.

    (Review) RGM Rearguard vs. tailgate scratches...

    There are one or two previous threads on the general topic of rear bumper protection that discuss the product. The threads may not have identified the manufacturer's name, but I extracted enough information from the threads to track down the manufacturer's UK contact information. I am glad I did.

    Several members of this forum, including yours truly, have purchased and installed this bumper guard on their vehicles. IMO, it is a great product.

    Occasional Vampire Battery Drain While Parked

    All systems are shut off during the day. The only potential system activation is when I remotely connect to the ConnectedDrive app to check on the vehicle’s status, but I have also accessed that app on days when there is no battery drain. I am thinking the best possible explanation is that the...

    Occasional Vampire Battery Drain While Parked

    Over the past year, I have maintained a daily log keeping track of my battery usage and electricity consumption rate during my 60 mile round-trip daily commute to work. During each normal work day, my i3 sits locked in a parking garage for about 10 hours before I unlock the car and head home. I...

    Electric Camaro Coming??

    Very interesting concept car. I have been generally disappointed by the car manufacturers' overly-optimistic promises about upcoming EV models and their anticipated sale availability dates in the U.S. Case in point--VW has made many promises over the past 5 to 7 years about upcoming EV models...

    Question about 20 inch rims on i3

    Well, my delimna has been solved. The 2017 I am interested in purchasing has the turbine alloy wheels. The item description for the vehicle incorrectly stated that they are 20 inch wheels, but I confirmed they are 19 inch wheels by visual inspection. So, no problem now. Thanks.

    Question about 20 inch rims on i3

    I am thinking about selling my 2016 i3 Rex and purchasing a 2017 i3 Rex with the larger battery pack. The 2017 I am considering has the 20 inch rims. My understanding is that Bridgestone only offers a summer season tire for the 20 inch rims. My question is whether those tires would be...

    Rex Junior and the tale of comfy winter driving without using the heater.

    After trying many different approaches for trying to stay warm while commuting during really cold days without using the climate control, the best approach I have found (at least for me) is using the seat heater and a small Honeywell 250 watt ceramic heater plugged into a portable rechargeable...

    12 volt battery failure question

    Update—I took my 2016 Rex to the dealer today. The service tech determined that the 12 volt battery was defective (no surprise there), and the dealer replaced the battery under warranty.

    Possibly the 12 volt battery starting to fail.

    12 volt battery failure question

    Thanks for all the insightful replies. Leaving the vehicle connected to my home charger did the trick. The 12 volt battery received enough charge to power up all the electronics and put the vehicle in a ready state, and I drove it a few miles this afternoon with no problems. I am sure the...

    12 volt battery failure question

    I seem to recall a post (maybe from jadnashuanh) that indicated that the vehicle's HV battery charging system has a process for recharging the 12 volt battery when needed, but I could not find the post. If so, that might explain why the car is currently accepting a charge, albeit at a very low...

    12 volt battery failure question

    I woke up this morning with my i3 Rex being completely dead with no remote or electrical or power functions. There was no prior warning or warning signs. All symptoms point to a failure of the 12 volt battery. I was able to open the charging port hatch with the manual release and connect my...

    EV Li-ion battery lost 10% while parked for 4 hours

    On occasion, I have seen the SOC on my 2016 i3 Rex drop anywhere from 2% to 5% after sitting in a cold parking garage for 8 to 12 hours during the winter months. I attributed the SOC loss to the loss of capacity caused by the cold temperatures while the vehicle is sitting idle.

    Hold state of charge vs. normal US REX operation

    Like any ICE unit, I would think the Rex engine would occasionally need to run an extended period of time to fully warm up. After coding my car to activate the hold SOC function, I use the Rex on my work commute in the afternoons (an hour commute covering 30 miles of distance) 3 or 4 times a...

    ISTA Install Help

    Speaking from personal experience of performing the battery reinitialization on my i3 Rex about 10 months ago, I agree with Alohart that the process most likely frees up some of the buffer capacity that the BMS had removed from the usable battery capacity. Based on the reports of others and my...

    Coolant Reservoirs on BMW i3 Rex

    In the i3 owner's manual, it shows two coolant reservoirs in the frunk, one for the climate control system and one for the "drive." I presume the "drive" reservoir is not for the Rex engine coolant. Is the Rex coolant reservoir in the rear under the engine cover near the oil dipstick? Thanks for...
