- D1TeamCross-functional team assembled: Battery Engg (M. Iyer), SQA (P. Nair), Warranty (A. Rao), Voltar Cells liaison (S. Kapoor).
- D2ProblemEV-2 vehicles idle 5–7 days show 12V drain requiring jump-start. 1,247 VINs across Pune build weeks W18–W24, exposure $4.82M.
- D3ContainmentSleep-mode current cap engaged via OTA on 894 in-service VINs. Field bulletin SB-EV2-081 issued to 214 dealers within 48h.
- D4Root causeBMS wake-latch remains asserted 4.2× spec when HV isolation MOSFET tail-current exceeds 3.1mA — observed on Voltar cells with lot-B interconnect. Confirmed on 214 telematics traces.
- D5Corrective actionsBMS firmware 3.1.7 raises isolation threshold and enforces 90s wake-timeout. Voltar interconnect PPAP re-run. See CAPA-1207, CAPA-1198.
- D6ImplementationOTA rollout to 1,247 EV-2 VINs staged over 7 days. Manufacturing cut-in from build week W27. PLM change CR-8821 sent to engineering approval.
- D7Prevent recurrenceSPC monitor added to intake test for sleep-mode current. Predictive Quality Agent watches drift on every EV-2 pack.
- D8Team recognitionFindings and remediation credited to CausalQ Orchestrator, Root-Cause Agent, Warranty & Field Agent and Voltar SQA team.
