MG Windsor EV Owners Warn: DC Fast Charging Glitch Plagues India's Hottest EV—Fix Begins!
India’s top-selling electric SUV, the MG Windsor EV, has hit a snag: multiple owners report persistent failures with DC fast-charging, prompting frustration—and growing concern over support and resolution.
What’s Going Wrong?
- Owners claim the vehicle begins charging then disconnects within seconds, especially on major public networks like Zapp, EV Dock, and Reliance Jio‑BP.
- Strikingly, other EVs—even MG ZS EV—charge normally on these same chargers.
- Reddit posts underline the issue:
“It doesn’t charge at DC chargers. Have to try multiple times…”
MG's Fix: BMS + HV Battery Software Update
To address the fault, MG has issued a Battery Management System (BMS) and high-voltage battery software update, accessible at authorized service centers. The estimated installation time is 30–60 minutes.
Dealerships have begun proactively reaching out to customers for scheduling the update rollout.
Real-World Customer Impact
Customers’ experiences reflect legitimate concerns:
- One LinkedIn user described spending nearly a month waiting for a solution that never fully materialized, despite service center visits and MG’s slow responses.
- Broader owner-group forums reveal widespread DC charger failures across multiple Windsor Pro units.
- Workarounds like keeping the car unlocked during charging were mentioned but remain unconfirmed.
EVINDIA Insight: Why It Matters
High Visibility, High Stakes
The Windsor EV played a key role in establishing JSW MG’s EV leadership in the ₹15–20 lakh segment. A widespread charging fault raises serious reputation and trust concerns.
Technical Complexity & Support Response
While DC fast-charging issues are often infrastructure-related, the fact that software alone is being positioned as the fix highlights potential design limitations. Customers expect clearer communications—not finger-pointing at third-party chargers.
Broader Implications for MG
A vehicle’s charging reliability is fundamental. With competitors like Tata, MG, Mahindra, and Ola racing ahead, customer confidence is king. MG’s roll-out of this patch is just step one.
What Should Owners Do?
- Visit any authorized MG service center to get the BMS and HV battery software update.
- Confirm whether your VIN or variant is covered under the fix.
- Request documentation on the update—some users report repeat visits and failures before resolution.
What Potential Buyers Should Ask:
- Has the charging issue been resolved on your test-drive model?
- Is the BMS update already applied/available?
- Can you verify third-party charging compatibility?

· The MG Windsor EV’s DC fast-charging failure issue has understandably sparked concern. While the software update offer is a welcome step, delays and customer complaints over support remain unresolved.
