Why does the exact Tesla alert ID matter?
Record the exact alert ID, including underscores, suffixes, and companion alerts. Tesla alerts that look similar can point to different modules, timestamps, and service procedures.

Affected Tesla Models
What You May Notice
- Thermal Architecture System alert: Firmware's supported drivetrain type does not match drivetrain type reported by vehicle's gateway. Firmware's supported
- Reduced charging speed in cold weather or battery pre-conditioning required
- HVAC performance may be slightly affected
How to Diagnose and Resolve
- 1 Reboot the vehicle
- 2 Check coolant levels if accessible (Model S/X only)
- 3 Avoid DC fast charging until battery temperature normalizes
- 4 Schedule service if the alert appears in warm ambient conditions
Severity Notes
TAS-A319 is an Alert in the Thermal Architecture System system. Confirm the vehicle screen and Tesla app show no driving or charging restrictions, and schedule service if the alert returns.
