I had to take my wife to the ER today had 3/4 battery when we needed to go full tank of gas about 10 miles b4 we got to ER the REX kicked on but driving aggressively to get her there ASAP battery was 2.5% it was hot here in Iowa 98 F or so and no shade in parking lot, we came out about 8 hours later. We get in it to go home says 0.0% and get charge error and no REX kicking in. but as we all know 0.00% charge is the false bottom limit set by BMW TO BAD WONT GET ME THE AN EMERGENCY 5% to get to Charge-Point or let REX Kick IN
Totally surprised since last week REX kicked in and I stopped at grocery store for 15-20 minutes on REX only and started REX and went home another 30 miles.
And its a 2014 60AH with REX
Anyone else ever had that where too low for REX to start, and low voltage 12v fully charged,
Thanks in advance,
