Urgent Escalation – TVS iQube Battery Failure Immediately After Service | MH14 KR6734

Community

Dear TVS Motors Customer Care and Senior Management,

I am writing to formally escalate a serious issue concerning my TVS iQube electric scooter bearing Registration Number MH14 KR6734.

My scooter has completed approximately 18,000 km in 3 years and had been functioning satisfactorily without any major battery or charging-related issues.

Recently, I visited your authorized service center and the following work was carried out:

  • Running service
  • Brake repairs
  • Replacement of a fibre body part

Immediately after this service visit, I began experiencing severe problems that never existed before:

  1. The scooter shuts down after approximately 40 km of riding.
  2. The battery charging stops automatically at around 76%.
  3. The range has reduced drastically compared to its earlier performance.

These issues started only after the service activities were performed on my vehicle.

Given the timing of these failures, I am deeply concerned that something during the servicing process may have adversely affected the battery system or related electrical components. The fact that the battery started malfunctioning immediately after the service raises serious questions that require investigation.

I respectfully request:

  1. A detailed technical investigation by TVS technical experts.
  2. Complete diagnostic reports of the battery, BMS, charger, wiring, and electrical systems.
  3. Service records and details of all work performed during the recent service visit.
  4. A written explanation of the root cause of these issues.
  5. Replacement of the battery pack at no cost if the investigation confirms that these problems are linked to the servicing activity or any negligence during service.

As a loyal TVS customer, I expect transparency, accountability, and a fair resolution. I do not believe a battery that was functioning normally before service should suddenly develop these critical issues immediately afterward without a clear reason.

I kindly request a response from senior management and a resolution at the earliest.

Vehicle Details:

  • Registration Number: MH14 KR6734
  • Model: TVS iQube
  • Odometer: Approximately 18,000 km

I look forward to your prompt intervention and resolution.

Regards,
Satish Devadiga

Dear @Satish_Devadiga,

Welcome to the citizen.complainthub.org community. Your suspicion is entirely justified, and your draft is a strong, logically sound escalation. In the world of electric vehicles (EVs), there is rarely such a thing as a coincidence when a perfectly healthy battery suddenly develops chronic charging and range issues immediately after a workshop visit.

Based on the symptoms you described (stopping at 76% charge and shutting down at 40km), here is the factual, technical reality of what likely happened to your iQube, and how you must structure your escalation to hold the service center accountable.

The Technical Reality: What Likely Happened

The TVS iQube relies heavily on a Battery Management System (BMS) to balance the internal cells and communicate with the charger. Your scooter just underwent a “running service” and a “replacement of a fibre body part.”

Pinched/Disconnected Wiring: Replacing body panels requires removing the existing fiber elements. It is highly probable that during reassembly, the mechanic accidentally pinched the main wiring harness, or partially dislodged the communication cable connecting the BMS to the display/charger.

Water Ingress: Running services typically include a high-pressure water wash. If a panel was improperly fitted, or if a waterproof seal around the BMS or charging port was compromised during the bodywork, water may have shorted a sensor.

Cell Imbalance Failsafe: When the charger stops exactly at 76%, it means the BMS is detecting a critical fault (like a missing temperature reading or a voltage spike in one cell cluster due to a damaged wire) and is cutting off the power as a safety failsafe to prevent a thermal runaway (fire).

Your Multi-Level Escalation Strategy

The local service center will almost certainly try to blame “normal battery degradation” to avoid paying for their negligence out of pocket. You must bypass the floor mechanics and secure the digital evidence before they wipe it.

Secure the BMS Data Logs Immediately

Modern EVs record every single fault code with a timestamp. When you take the scooter back, demand a physical printout or a digital copy of the OBD (On-Board Diagnostics) / BMS Error Logs. This is your undeniable proof. The log will show exactly when the fault was first triggered if the timestamp matches the exact day it was in their service bay, they have no legal defense.

Escalate to the Area Service Manager (ASM)

Standard customer care emails often bounce back with templated replies. When you hand over the vehicle, refuse to deal with the Service Advisor. Ask for the direct contact details of the TVS Area Service Manager (ASM) for the Maharashtra (MH14 / Pune) region. The ASM represents the manufacturer, not the franchise, and has the authority to approve a free battery pack replacement under goodwill or workshop warranty.

Set a Legal Precedent (Deficiency in Service)

If the dealership refuses to share the diagnostic logs or tries to hand you a massive repair bill, your drafted email is the perfect foundation for a legal notice. Under the Consumer Protection Act, this falls under Deficiency in Service.
