The defect explained
Premature battery capacity fade; sudden BMS software lockouts causing vehicle shutdown; service centers stalling repairs for 30–45+ days due to replacement battery pack shortages.
- Battery packs that lose usable range faster than advertised under Indian heat and stop-go traffic
- BMS firmware lockouts that immobilise the vehicle until brand-authorised service intervenes
- Chronic shortage of replacement packs at authorised service centres
- Job cards that sit for weeks without written repair timelines or loaner transport options
Consumer rights awareness
Informational awareness under the Consumer Protection Act, 2019 (not legal advice): unreasonably delayed warranty repairs, failure to honour battery/BMS warranty commitments, or leaving a consumer without a working vehicle for prolonged periods may amount to deficiency of service. Keep job-card dates and State of Health (SOH %) printouts; this site does not provide legal representation.
Tip: Always demand a written State of Health (SOH %) diagnostic sheet during service visits and record official job-card intake dates.
Evidence collection checklist
- Purchase invoice, warranty booklet, and VIN / battery serial photos
- Written State of Health (SOH %) diagnostic sheet from the service visit
- Official job-card intake date and every follow-up stamp
- Photos/videos of BMS error codes or sudden shutdown events
- Chat/email trail of promised vs actual spare-part arrival dates
