Proton Persona Common Problems Malaysia
Persona top three: Punch CVT shudder from neglected fluid (40,000 km, Punch-specific fluid only — NOT Toyota WS), timing belt at 60,000 km (interference engine), A/C compressor failure. All maintenance-driven. Budget but capable sedan.
Proton Persona Common Problems
- Punch CVT shudder — neglected fluid (change every 40,000 km with Punch-specific fluid)
- Timing belt at 60,000 km — interference engine, belt snap = bent valves
- A/C compressor failure — same issue as Saga
- CVT noise / belt squeal — low fluid or worn CVT belt
