When DIY isn't enough — book an ev.care technician for your JBM EcoLife
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. JBM EcoLife battery and motor faults compound: a minor BMS imbalance left untreated can kill the whole pack inside 6 months.
ev.care dispatches a DIYguru-certified technician to your location with a 2-hour callback. Diagnostic site visit is a flat ₹399, transparent quoted before any work begins. Common JBM EcoLife repairs are covered under our Annual Care Plan.
