Yes, some Changan Alsvin owners have reported engine knocking sounds, especially during cold starts o r under hard acceleration. The issue is often linked to fuel quality o r incorrect spark timing. Using high-octane fuel and regular engine tuning can help minimize knocking. In a few cases, engine software updates from authorized dealerships have also reduced this issue. If knocking persists, its recommended to get the spark plugs, injectors, and engine timing checked.
