Handling a "Check Hybrid System" Warning in a Malaysian Traffic Jam MyMechanic

• High battery temperatures from extended idling and heavy A/C load.
• Inverter or cooling fan issues affecting hybrid thermal control.
• Degraded hybrid battery performance or sensor faults.
• Electrical glitches that may briefly clear after a restart.

• More idling and less airflow reduce cooling efficiency.
• Battery assist works harder at low speeds with A/C demand.
• High ambient temperatures raise thermal load on the pack and inverter.

Immediate steps to take

• Stay calm and monitor power—many cars do not shut down immediately.
• Move to a safe bay: hazards on, wheels straight, triangle when safe.
• Restart once: a clean power cycle can clear a transient fault.
• Escalate if the light persists or performance drops—avoid long drives with the warning on.

• Roadside support when the warning appears on highways or in jams.
• Basic triage for thermal, electrical, and 12V stability concerns.
• Towing coordination if deeper diagnostics are needed.
• Coverage across Malaysia tailored for SG‑registered hybrids.

Final thoughts

The “Check Hybrid System” warning is a prompt to act, not panic. Stage safely, try one restart, and escalate if it returns. With MyMechanic supporting SG hybrids across Malaysia, help is close—whether on the expressway or in city traffic.
