Simptom

• ABS warning light stays on while driving
• ABS and stability functions disabled while the light is lit
• Light appears after driving through deep water or potholes, then clears
• Intermittent light that corresponds to hitting a bump

Punca

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.

Penyelesaian

A workshop reads the stored ABS code and it names the wheel. Tell them when the light came on, whether it was deep water or a pothole, and whether it clears by itself. That story points at dirt on a sensor rather than a dead unit. A basic scan runs RM80 to RM150, a full all-module read RM150 to RM250, and most shops waive the fee if you book the repair with them. A replacement sensor lands around RM190 fitted. Braking feel stays normal with ABS disabled, but stopping distances on loose or wet surfaces get worse, so do not sit on it for months.

Simptom

• Vent air cools weakly, worst in slow traffic and afternoons
• Compressor clutch cycles on and off rapidly
• Cold at highway speed but weak at idle
• Oily residue around condenser pipes or hose joints (leak indicator)

Punca

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.

Penyelesaian

Get a pressure test and leak check first. Clean the condenser and fan before replacing anything, since a blocked condenser alone mimics a weak compressor. Regas with the correct measured charge if the system holds. If the clutch slips constantly or the compressor rattles, replace it; a reconditioned Denso unit is the budget path, a new Denso unit the durable path. Change the receiver-drier every time the circuit is opened.

Simptom

• Engine dies while idling at a junction, a car park or a drive-through
• Long crank before it fires, and sometimes no start at all
• Power drops away under load, then comes back after a restart
• No warning light, no stored complaint the owner can see

Punca

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.

Penyelesaian

Ask a Perodua service centre whether your car is in the campaign, using the chassis and engine numbers rather than the registration date. The replacement costs nothing and takes about half a day. Perodua said the failure shows up when the car is stationary rather than at speed, but a car that has just cut out at a traffic light is a car that will not restart, so do not leave it on the list for months. If the pump has already been changed, the invoice is the proof, and it is worth keeping with the service book when you sell.

Simptom

• Gegaran atau getaran pada kelajuan rendah (10-30 km/j)
• Kelewatan apabila memecut dari keadaan berhenti
• Bunyi luar biasa dari transmisi pada RPM rendah

Punca

Sistem belt-dan-pulley pada CVT Perodua boleh mengalami gegaran apabila cecair CVT merosot. Gegaran pada kelajuan rendah lebih ketara dalam lalu lintas berhenti-jalan dan menjadi lebih teruk di iklim panas.

Penyelesaian

Penggantian cecair CVT dengan CVTF FE spesifikasi OEM selalunya menyelesaikan masalah ini. Jika masalah berterusan selepas penukaran cecair, periksa belt CVT untuk kehausan. Pengesanan awal mengelakkan kos pembaikan yang mahal.

Simptom

• Getaran terasa melalui stereng dan dashboard semasa idle
• Bunyi clunking semasa bertukar dari Park ke Drive
• Pergerakan enjin kelihatan semasa revving dalam neutral

Punca

Engine mounts Myvi menggunakan rubber bushings untuk menyerap getaran. Dari masa ke masa, terutamanya dalam keadaan trafik stop-go yang biasa di bandar-bandar Malaysia, getah menjadi rosak dan merekah. Mount sebelah kiri (sebelah penumpang) paling mudah mengalami kegagalan disebabkan beban tork enjin.

Penyelesaian

Gantikan engine mount yang haus. Mount sebelah kiri adalah yang paling kerap terjejas. Periksa ketiga-tiga mount apabila satu gagal; yang lain mungkin hampir mencapai akhir hayat. Penggunaan mount OEM disyorkan untuk prestasi NVH yang terbaik.

Simptom

• Idle flutters or hunts between low and normal rpm
• Creep feels jerky at parking speed (CVT surge from idle instability)
• Idle dips when the aircond compressor kicks in
• Slight hesitation when pulling away from a stop

Punca

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.

Penyelesaian

A workshop cleans the throttle body and finishes with an idle relearn on a scan tool. A spray-only clean runs RM80 to RM120 and often comes back. A full clean with the relearn runs RM150 to RM250. Tell them the idle hunts and dips when the aircond cuts in, so they start at the throttle body rather than the gearbox. Leave the relearn to the shop that did the work. The battery disconnect trick at home is a coin toss, and a bad idle for a week is a poor way to save RM40.

Simptom

• Fan runs only on the highest setting; the lower speeds do nothing
• The fan works, then stops on one setting and later comes back
• Air stays cold at full blast but the cabin is noisy and the cold is uneven
• Speed settings die one at a time, starting with the slowest

Punca

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.

Penyelesaian

Replace the resistor pack rather than the blower motor. A workshop reaches it behind the glovebox in half an hour, and the part is sold for the third-generation car by Malaysian listings. Budget RM80 to RM140 fitted at 2026 prices. If nothing works on any setting, including the top one, that is the motor or its fuse and a different job.

Simptom

• Bunyi berderak dari kawasan dashboard di jalan kasar
• Bunyi berdecit dari trim A-pillar
• Rasa longgar pada centre console

Punca

Model Myvi pengeluaran awal (2018-2020) mempunyai isu fit-and-finish di mana klip trim dalaman tidak dipasang dengan ketat. Dashboard dan trim A-pillar amat mudah bergetar.

Penyelesaian

Sapukan pita felt berpelekat pada titik sentuhan di belakang panel trim. Gantikan klip plastik yang pecah. Kebanyakan derakan boleh dihapuskan dengan kos di bawah RM10.

Simptom

• Whistle or whine that follows road speed, loudest from about 40 to 80 km/h
• Appears when you press the accelerator and fades when you lift off
• Easy to hear with the radio off, and easier with passengers in the car
• No shudder, no delayed engagement, no warning light

Punca

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.

Penyelesaian

Nothing needs replacing when the noise is the belt whine: it is how the gearbox sounds, and it does not get worse with mileage in the reports so far. Two things separate it from a fault. A failing alternator or belt idler will also whine with the car standing and the engine revved in neutral, because it is driven by the engine rather than by road speed. A CVT that is actually slipping comes with revs that climb without the car speeding up, shudder on pull-away, or a delayed engagement when you select drive.

Simptom

• Tingkap bergerak perlahan atau tersangkut pada separuh jalan
• Tingkap turun sedikit apabila tertutup sepenuhnya (salah jajaran anti-pinch)
• Regulator tingkap mengeluarkan bunyi mengisar

Punca

Model Myvi produksi awal (2018-2021) menggunakan pemasangan motor dan regulator tingkap yang boleh haus sebelum waktunya. Berus motor haus dan kabel regulator boleh putus, terutamanya pada tingkap yang kerap digunakan (bahagian pemandu paling terjejas).

Penyelesaian

Gantikan pemasangan regulator tingkap. Motor dan regulator dijual sebagai satu unit. Lumurkan saluran tingkap dengan semburan silikon semasa penggantian untuk memanjangkan hayat unit baharu.
