Yes:

Owners have reported laggy throttle, unexpected downshifts, and shifting errors linked to TCU software bugs.

Firmware updates have been quietly released by Changan:

Some workshops perform TCU recalibration during scheduled service.

Not all dealers proactively notify customers about updates.

Software glitches were more common in early 2021–2022 models, with improvements in later builds.
