There is a recall for that problem, see here, https://recalls-rappels.canada.ca/en/alert-recall/transport-canada-recall-2023011-canadian-motor-import-inc#section_3

Issue
Issue:
On certain vehicles, a programming error could cause the hazard lights to turn on unexpectedly. As a result, you would no longer be able to signal your intention to turn with the turn signals.

Safety Risk:
Hazard lights that do not work properly could cause confusion. Additionally, turn signals that do not work may cause a person not to recognize that the vehicle intends to turn. Both of these conditions could increase the risk of a crash.

Corrective Actions:
CFMOTO recommends that you should not drive your vehicle until the recall repairs are completed. CFMOTO will notify owners by mail and instruct you to bring your vehicle to a dealership to inspect the manufacturing code on the flasher module. It will be replaced, if necessary.

my 2023 u600 started to do this too, cold weather, dealer sais it is the module, but they also say it has been changed already from a recall before i purchased it. 67$ or so, not sure if i should change again or not, anyone have a different solution for this?
