When DIY isn't enough — book an ev.care technician for your PMI Electro Mobility
If a fault repeats after the steps above, if any dashboard error code is showing, or if you notice any unusual smell, heat, or sound from the battery pack — stop driving. PMI Electro Mobility battery and motor faults compound: a minor BMS imbalance left untreated can kill the whole pack inside 6 months.
