What each repair involves on the Lancer, when to inspect or replace, and what our invoices say it costs
The figures are from our invoices. Scheduled maintenance follows the requirements for your car's engine, gearbox and model year; other repairs are assessed from symptoms, inspection and diagnostic results rather than a universal age or mileage. The notes under each repair are general guidance for cars driven in Singapore, not statistics.
Spark plugs and ignition coils on the Mitsubishi Lancer
17% of the Lancer registrations in our records had at least one invoice involving this work (9 of 52, 10 invoices in all). On the bill, this item typically came to about $150 (middle half $150 to $200, 7 recent priced bills, GST included; other work on the same bill is not counted).
Spark plugs ignite the fuel mixture, while ignition coils supply the voltage they need. Failure may cause rough idling, hesitation, weak acceleration or an engine warning lamp. Continued misfiring can strain the catalytic converter and increase fuel use.
We begin with a fault-code scan, then inspect plug condition and test coil output under load. We replace the failed ignition part, record the evidence and give you an honest quote before work starts.
Service interval: Spark plugs have a scheduled interval that depends on the engine and plug type, and we confirm it for your car. Ignition coils are replaced on diagnosis, not on a schedule, and a misfire does not by itself mean a coil has failed.
Maintenance and early warning signs: Keep to the plug interval and have misfires checked early, because unburnt fuel can damage the catalytic converter. Early signs: rough idle, hesitation, a flashing engine light.
Battery replacement on the Mitsubishi Lancer
17% of the Lancer registrations in our records had at least one invoice involving this work (9 of 52, 9 invoices in all). On the bill, this item typically came to about $150 (middle half $150 to $200, 7 recent priced bills, GST included; other work on the same bill is not counted).
The battery supplies current for starting and helps keep the electrical system stable. Slow cranking, dim lights or repeated warning messages can point to a weak battery. Leaving it unresolved can overwork the charging system and cause erratic electrical behaviour.
A charging-system test and battery load test separate a weak battery from an alternator or connection fault. We log the readings, recommend only the faulty part and confirm an honest quote before any work begins.
When to inspect or replace: The starter battery is tested at every service and replaced on the test result rather than at a set age. Cars with a separate auxiliary battery for the stop-start system or the electronics have that battery tested and replaced the same way, and it is counted in this row. Hybrid drive batteries are a separate matter.
Maintenance and early warning signs: Short trips and daily aircon use are hard on a battery in Singapore; give the car a longer run where you can, switch accessories off before the engine, and park in shade. Early signs: slow cranking, lights dimming at idle, stop-start no longer working, a warning about the auxiliary battery, electrical warnings that come and go.

Gearbox oil changes on the Mitsubishi Lancer
15% of the Lancer registrations in our records had at least one invoice involving this work (8 of 52, 9 invoices in all). On the bill, this item typically came to about $150 (5 recent priced bills, GST included; other work on the same bill is not counted).
Gearbox oil lubricates moving parts, carries heat away and supports hydraulic control. Degraded or low fluid may cause delayed engagement, rough shifts or shuddering. Leaving the cause unchecked can accelerate wear and spread debris through internal parts.
We check fluid level and condition, trace leaks and road-test shift behaviour to separate an oil change from a leak or internal component fault. We document the evidence and give you an honest quote for the right work before anything starts.
Service interval: Follow the interval and fluid specification for your gearbox and model year; they differ between gearbox types even within one model, and we confirm them for your car. Where the maker lists no change for the life of the car, ask us whether a preventive change makes sense for your gearbox and driving.
Maintenance and early warning signs: Use the specified fluid and fill procedure, with the filter where your gearbox has a serviceable one, and avoid hard launches while the gearbox is cold. Fresh fluid is maintenance, not a cure for a gearbox that is already faulty. Early signs: a burnt smell, dark fluid, shifts that have become rough.

Sensors, switches and control modules on the Mitsubishi Lancer
13% of the Lancer registrations in our records had at least one invoice involving this work (7 of 52, 8 invoices in all). On the bill, this item typically came to about $300 (middle half $300 to $400, 5 recent priced bills, GST included; other work on the same bill is not counted).
Sensors report operating conditions, switches send commands and control modules manage electrical functions. A fault may appear as a warning lamp, an intermittent feature or unexpected engine behaviour. Damaged wiring or unstable voltage can eventually harm connectors and related electronics.
We scan fault codes, compare live data and test the relevant circuit at its connectors. That shows whether the sensor, switch, wiring or module is at fault, which we document before providing an honest quote for the repair.
When repair may be needed: Diagnosis-led: a fault code names a circuit, not a part, so we test the sensor, switch, wiring and module before anything is replaced.
Maintenance and early warning signs: Keep sunroof drains, door seals and boot seals clear so rain stays out of the cabin and boot, fix battery and charging faults early, and never jump-start with the polarity guessed. Early signs: warning lights that come and go, features that drop out in the rain, an unexplained battery drain.
Fan belts, tensioners and pulleys on the Mitsubishi Lancer
10% of the Lancer registrations in our records had at least one invoice involving this work (5 of 52, 5 invoices in all). On the bill, this item typically came to about $150 (5 recent priced bills, GST included; other work on the same bill is not counted).
The belt drives engine accessories, while the tensioner and pulleys keep it aligned and tight. Squealing, chirping or rattling from the engine bay can signal wear or a failing bearing. A slipped or broken belt can stop a driven accessory and lead to charging or cooling trouble.
We inspect belt wear and alignment, then check tensioner movement and pulley bearings for noise or play. We identify the worn drive part, note it in the job record and set out an honest quote before repair work starts.
When to inspect or replace: The drive belt is inspected at every service and replaced on condition or on your car's schedule; the tensioner and pulleys are assessed separately.
Maintenance and early warning signs: Fix oil and coolant leaks that soak the belt, and have squeals or rattles checked before the belt fails. Early signs: a squeal on cold start, a rattle at idle, cracked belt ribs.
Brake pads, discs and wear sensors on the Mitsubishi Lancer
10% of the Lancer registrations in our records had at least one invoice involving this work (5 of 52, 5 invoices in all). Fewer than 3 recent bills price this item on its own line, so we quote it on WhatsApp after diagnosis.
Brake pads press against the discs to slow the car, while wear sensors alert the driver when fitted parts need attention. Squealing, grinding, vibration or weaker braking can signal wear. Waiting can score the discs, overheat brake parts and reduce braking control.
We measure the pads and discs, then inspect the wear sensor and its wiring. We record which brake part is worn and give you an honest quote before replacement work begins.
When to inspect or replace: Pads and discs are measured at every service and replaced by thickness and condition against the limits for your car, not by mileage. Discs are judged on the same measurement, not on a fixed number of pad changes.
Maintenance and early warning signs: Brake early and gently, leave a gap so you roll instead of stopping at every light, and use engine braking on long descents; stop-and-go traffic wears pads and discs faster. Early signs: squeal, grinding, a pulse through the pedal, a wear warning on the dash.

Access, related damage and hidden electrical faults can move the repair scope up, while an isolated fault keeps it down. The statistic shown for a repair comes from documented invoices, but it is not a quote for your Lancer.
