常见问题
覆盖范围已复核车主反馈的问题、症状、原因与解决方法，按严重程度排序。
CVT 钢带磨损与打滑
CVT 钢带和皮带轮会随使用时间磨损，尤其是未按建议间隔更换 CVT 油液时。 高温驾驶条件（交通拥堵、山路驾驶）会加速磨损。
Air Conditioner Not Cold
The most commonly reported Iriz aircond faults split into three groups: low refrigerant from O-ring or hose leaks, a worn compressor with the magnetic clutch slipping or failing (a fault repeatedly covered by Malaysian repair channels for this model), and a dirty or damaged condenser that cannot reject heat in Malaysian traffic. Age matters; units older than 6 years accumulate several of these at once.
走走停停交通中的CVT顿挫感
Iriz使用的Punch CVT为燃油效率而调校，这导致了明显的橡皮筋效应。 低速颤抖可能因CVT油液劣化或CVT钢带磨损而加剧。在大多数情况下， 这是变速箱的特性而非故障。
Aircond blower only works on full speed
The blower resistor pack, a small module on the blower housing, controls the lower fan speeds. When its coils or thermal fuse fail, the motor only gets full power, so speed 4 becomes the only working setting. It is a wear item on the Iriz the same way it is on the Saga BLM and Persona, and the parts are shared across those cars.
Engine Mount Wear
The Iriz's rubber engine mounts compress and crack with age and heat cycles, and engine mount deterioration is one of the commonly listed complaints for this model in Malaysian ownership write-ups. City stop-go driving and low-speed CVT torque reversals load the mounts hard. The upper and left-side mounts typically show deterioration first.
Clunk from the front over speed bumps
The front strut mount and its bearing sit at the top of each strut and take the road load into the body. The rubber in the mount perishes, and the bearing dries out, so the strut can move a millimetre or two and knock. The Iriz carries a lot of weight on the front axle for a small hatch, and Malaysian road surfaces speed the process up.
Power Window Failure
Early pre-facelift Iriz models (roughly 2014 to 2018) used a window regulator and motor assembly that wears ahead of schedule, particularly on the driver's door which cycles most often. Owners across Malaysian owner groups and forums report repeated failures on first-generation examples, to the point where Proton covered the power window system (regulator, motor, switches and run channel) under a specific warranty clause in its service booklets and later extended window-side coverage across its range.
仪表台和内饰异响
早期生产的Iriz车型（2014-2018款）存在装配工艺问题， 内饰饰板卡扣和仪表台面板未能牢固固定。A柱饰板在高速 行驶时尤其容易产生振动。
Musty smell when the aircond starts
Damp dust and pollen sit on the cabin filter and the evaporator core, and the cool, dark airbox is a good place for mould. Malaysian humidity does the rest. A filter that has been in the car for two years or more is the usual starting point, and the Iriz filter is behind the glovebox where owners never see it.
Manual gearbox busy at highway speed
The five-speed manual was geared for town work, not for cruising. Fifth is short enough that highway speed keeps the engine high in its rev range, which is why the manual Iriz is fun on a back road and tiring on a drive to Penang. Nothing is broken. It is the ratio in the box.
Knock from the rear over uneven road
The Iriz runs a torsion beam at the rear, mounted on two trailing arm bushes. Those bushes take every sideways load and they crack and soften with age, which lets the beam move in its mounts. The noise sounds like a loose spare wheel or a body rattle, which is why it gets chased in the wrong place first.
