What this guide covers

• Tiago EV not charging from home wallbox
• Battery percentage drops 5-8% overnight without driving
• Cabin smells of plastic after fast charging
• Touchscreen freezing on boot
• Tyre pressure warning when tyres are correctly inflated

5 common Tata Tiago EV faults — and how to fix each

1. Tiago EV not charging from home wallbox

Step-by-step fix:

1. Most home wallboxes need a Type-2 to Type-2 cable; Tiago ships with a Type-2 inlet.
2. If your wallbox is the older Type-1, you need a converter (~₹3,500).
3. Verify the wallbox MCB is rated for 32A; under-rated MCBs trip silently.

2. Battery percentage drops 5-8% overnight without driving

Step-by-step fix:

1. 12V aux battery is failing.
2. The HV pack stays sealed overnight, but the aux runs telematics + immobiliser.
3. Replace if drop > 3% in 12 hours of parked time.

3. Cabin smells of plastic after fast charging

Step-by-step fix:

1. Normal during the first 5-10 fast charges as the cables heat-cycle.
2. If it persists beyond 1,000km, get the DC inlet inspected — a melted pin connector means the next fast-charge could damage the BMS.

4. Touchscreen freezing on boot

Step-by-step fix:

1. Hold the power button on the screen for 12 seconds — forces a soft reboot.
2. If it still freezes, disconnect the 12V aux battery for 60 seconds.
3. Persistent freezes after this point are firmware — book a Tata service for the OTA push.

5. Tyre pressure warning when tyres are correctly inflated

Step-by-step fix:

1. TPMS sensors recalibrate after 50km of driving.
2. If warning persists after 100km of mixed driving, one sensor is dying — Tata covers TPMS sensors for 3 years/45,000km.

When DIY isn't enough — book an ev.care technician for your Tata Tiago EV

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. Tata Tiago EV battery and motor faults compound: a minor BMS imbalance left untreated can kill the whole pack inside 6 months.
