Lithium Battery is failing to accept a FULL charge. When the car was purchased Nov 2022 the Lithium Battery would charge to 22 to 25 miles on electric. 25 miles Is the advertised electric range. In the past 2 years the Li battery degraded to reporting 100%, maximum 18 miles and today 100% at maximum 14 miles. Service Tech’s see 100% and report that “it is charging.” It is charged in a climate controlled garage generally on a level 2 charger, sometimes on the 110v charger supplied by BMW. I have tried both to find the best charging mode. SAME RESULT. On occasion when I get a fault, I will change to the BMW charging unit. Wait 5 minutes and try again. BMW reports that the software is up to date. Last night it indicated 100% 15 miles on the L2 charger. I switched to the BMW charge unit and it went down to 100% 14 miles on electric.
