2015 Tang drive-controller recall: why the remedy changes the discharge method for electric-mode failure
China’s recall for certain 2015 Tang vehicles addresses active discharge in the drive motor controller. Separate software measures from hardware damage.
If an older Tang cannot use electric-only mode normally and the quotation immediately lists a motor or drive-controller assembly, first check for the relevant manufacturer action. The Chinese recall for certain 2015 Tang vehicles identifies the controller's active discharge function. Its official remedy starts with software, helping buyers distinguish campaign requirements from separate hardware damage on the vehicle.
A controller abnormality does not establish motor failure
The Oct 17, 2025 notice states that component design selection may cause abnormal active discharge in some drive motor controllers during use. In extreme cases, circuit-board overheating damage may occur and electric-only drive mode may fail.[First defect description][S01]
These are distinct objects: the controller function, possible damage inside the controller and the resulting electric-mode failure. “Electric mode unavailable” alone cannot justify skipping controller checks and deciding that the motor must be replaced.
The software remedy changes the discharge method
The notice directs authorised dealers to update software and change the discharge method to motor discharge.[First rectification measure][S01] For this action, confirming completion of the specified software measure is more targeted than first seeking a visually identical used controller.
The software measure must not be interpreted as restoring every already damaged hardware component. If a fault already exists or inspection finds physical damage, the authorised repairer must address the actual vehicle. A preventive or corrective measure is not a guarantee that every fault is repaired.
Repair records should distinguish software work from physical replacement
Check whether a work order records this campaign's software update or hardware work supported by separate findings. “Electric drive handled” does not explain whether the specified measure was completed or whether additional replacement has a basis.
Electric-mode problems on the same model do not automatically create the same assembly order. Confirm the action, then assess actual damage so genuinely required components remain distinct from the software work.
Scope and verification
This article covers only Chinese action S2025M0165I, originally published on Oct 17, 2025. It concerns certain 2015 Tang series vehicles produced from Mar 28, 2015 to Jul 28, 2017, totalling 44535 vehicles. The notice explicitly identifies 2015 as the model year; the later dates define production. Coverage does not extend to subsequent Tang DM/EV vehicles or other markets.
The cited official text publishes neither VIN endpoints nor individual vehicles. No public data was available for the specific VIN scope; have the Chinese authorised representative check by chassis number. No public data was available for controller OE numbers, cross-version compatibility or replacement criteria after hardware damage. [To be verified] Verify ordinary parts compatibility using the VIN and local manufacturer parts catalogue rather than ordering on a claim that a part fits all older Tang vehicles.
