ABS Warning Light from Wheel Sensor
A wheel speed sensor can fail or get fouled by metal debris, cutting the speed signal to the ABS module. Sensor failures are among the most commonly cited causes of the ABS light in Myvi owner groups. On some cars the wiring harness to a sensor survives. On D20N Myvis the front sensors carry Perodua-style codes of the 89542-BZ120 / 89543-BZ120 type as listed by local parts sellers, but sensor codes vary by position and year, so confirm before ordering.
Air Conditioner Not Cold
Reported Myvi aircond failures cluster around three causes: refrigerant leaking past aged O-rings or the condenser, a worn Denso compressor whose magnetic clutch starts slipping, and clogged condenser fins that cannot reject heat in urban traffic. The compressor is the expensive one; separate Malaysian price guides put a new original Denso compressor well above a reconditioned or OEM-market replacement once labour is added.
Engine Dies or Cranks Long (Fuel Pump Campaign)
The Denso fuel pump fitted to early third-generation Myvis came from a batch caught in a global Denso recall. Solvent used during production was left drying for too long, which could crack the pump's surface and let it absorb fuel until the impeller deformed and the pump stopped. Perodua ran it as a special service campaign rather than a public recall: owners of affected cars were written to in stages, and the pump was swapped free. Cars built from October 2019 onward are not in the affected build range.
低速时CVT抖动
Perodua CVT采用钢带和皮带轮系统，随着CVT油液劣化，可能会出现抖动。 低速抖动在走走停停的路况中更为明显，在炎热气候下会加剧。
引擎支架磨损
Myvi的引擎支架使用橡胶衬套来吸收振动。随着时间推移， 尤其是在马来西亚城市常见的走走停停的交通状况下，橡胶会老化并开裂。 由于引擎扭矩负载，左侧（副驾驶侧）支架最容易失效。
Rough Idle from Dirty Throttle Body
Carbon and oil vapour deposits build up in the throttle bore and on the butterfly plate and idle air passages. Malaysian servicing guides describe sticky throttle body deposits as a routine Myvi issue in the 40,000-80,000km window, and it is worse on cars with higher idle hours in traffic.
Aircond Fan Only Works on One Speed
The blower resistor pack, which is the fan speed control, sits in the air stream behind the glovebox and drops voltage for each speed below maximum. When it fails, the top setting keeps working because full speed bypasses the resistor, so the fan appears healthy while every other setting is dead. Heat and damp in a Malaysian cabin are what kills it, not the blower motor.
颠簸路面上的仪表板异响
早期生产的Myvi车型（2018-2020款）存在装配和表面处理方面的问题， 内饰饰板卡扣未牢固固定。仪表板和A柱饰板尤其容易产生振动。
Whine or Whistle When Accelerating (D-CVT)
The D-CVT fitted from the November 2021 facelift uses a belt and pulley set, and the belt runs under load at a pitch the cabin hears as a whistle. Owners who took the car to a Perodua service centre were told it is the gearbox characteristic, and a technician demonstrated it on other D-CVT Myvis, including a 1.5. The pre-facelift four-speed automatic does not make the sound at all, which is why people who traded up notice it immediately.
Power Window Motor 故障
早期生产的 Myvi 车型 (2018-2021) 所使用的车窗电机和升降器总成 (regulator assembly) 可能会过早磨损。电机碳刷 (brushes) 会磨损，升降器钢索 (cables) 可能会断裂或起毛， 尤其是在经常使用的车窗上 (驾驶员侧影响最大)。
