Affected Models
Applies to all models
LAGTLAGTPLAPLASLAT
Likely Causes
  1. Coolant pump failure reducing flow rate through the battery thermal circuit
  2. Clogged or restricted coolant passages within the battery pack
  3. Low coolant level insufficient for effective heat dissipation
  4. Thermal management control module malfunction causing incorrect pump speed
  5. Ambient temperature extremes combined with sustained high-power operation
How to Fix It
1
Reduce vehicle speed and power output immediately to lower thermal load
2
Pull over safely and allow the battery and coolant system to cool for at least 30 minutes
3
Check coolant reservoir level and inspect visible hoses for leaks
4
Restart vehicle after cooling and monitor battery temperature readings on display
5
Schedule service if the fault recurs, as coolant pump or thermal valve replacement may be required
Pro Tip
This fix requires some technical knowledge. If you're unsure about any step, consider contacting support or a qualified technician.
