About SoCdrop.in
Why this site exists
Several owners of the Tata Punch EV (and related models) have reported sudden drops in battery state-of-charge (SoC) and usable range, and long, unclear service processes afterwards — weeks of restricted usage, repeated "observe and come back" advice, and no timeline for a fix.
We are not here to defame or bring disrepute to Tata Motors or any supplier. Most of us chose these cars because we believe in EVs. We want exactly one thing: that customers are treated fairly and get resolution in days, not weeks or months. When a case is resolved, we publish that just as prominently as the complaint.
What a good story looks like
- First-person and factual — your own car, dates, odometer readings, what the service center actually said. No speculation about causes, no accusations.
- The four facts — manufacture month, city, odometer km, observed drop %. These make the aggregate numbers on the homepage possible.
- Battery pack maker if you can find it — a label on the pack, visible under the boot floor, says Octillion or Tata AutoComp (TACO).
- Redact personal details — blur/crop VIN, registration number, phone, address from photos and job cards before uploading.
Useful parallel steps for affected owners
- Ask for a copy of your job card at every service visit — it is your record.
- Register a complaint with Tata Motors EV customer care in writing (email), so your timeline is documented.
- File a complaint on the National Consumer Helpline — free, online, and creates an official record.
