Vehicle report
Technical service bulletins are instructions a manufacturer sent its dealers about a known fault. They are not recalls and the work is usually not free, but they are the clearest signal of a problem the manufacturer already knows about.
TSB-725-01
Service action for removing CAN Bus resistors, cleaning & preventing DC to DC converter 12-volt cable corrosion, improving the location and visibility of the First Responders Cut Loop Labels, and improving the Motor Control Unit (MCU) high voltage cable dual clamp cable-ties locations.
TSB-0625-02
The updated VCU software includes enhancements for 12V and high-voltage battery conditioning, as well as resolving issues with incorrectly stored faults. The revised TCU software enhances the thermal management system and eliminates erroneously stored faults. The updated OTA software enables TCU and BMS diagnostics to be reported over the air. Additionally, the improved BMS software enhances fault detection and decreases the overall time required for cell balancing.
TSB-0425-01
Bulletin Title: Update the Vehicle Control Unit (VCU), Thermal Control Unit (TCU), and Telematics Module Unit (TMU) software to the latest version. Symptom: The existing VCU and TCU software may cause various fault codes to be stored in the vehicle's fault memory. The TMU does not currently support WiFi connection capability. Discussion: If equipped, the updated VCU software adds ePTO enhancements, improvements to 12V and high-voltage battery conditioning, and eliminates erroneously stored faults. The TCU software improves the thermal management system and eliminates erroneously stored faults. The TMU software adds WiFi connection capability to the vehicle.
Complaint counts are reports filed with NHTSA, not failure rates. A common model collects more of them than a rare one that breaks more often.
