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 create the spark that starts combustion, while ignition coils supply the required voltage. Wear or failure can bring rough idling, hesitation, hard starting or an engine warning light. Driving with a misfire can send unburned fuel into the exhaust and damage the catalytic converter.
We scan for fault codes, review misfire data, inspect plug wear and test the coils. We document the results and quote for the worn plugs or failed coil before work starts, rather than replacing the whole ignition system.
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 power for starting and supports the car's electrical systems. Slow cranking, dim lights and erratic warnings can point to a weak battery or poor connection. Waiting can strain the starter and leave the car unable to start.
We load-test the battery, inspect its terminals and check the charging output. The readings go into the job record, and you see the quote for the battery or connection fault before 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 smooth hydraulic operation. Degraded or contaminated fluid may show up as hesitant or rough shifting. Leaving unsuitable fluid in service can increase wear and turn a maintenance job into a larger repair.
We inspect the fluid condition, trace any leaks and road-test the shift quality before recommending a change. We record the findings and quote the fluid service or leaking part separately, so fresh fluid is not used to mask another fault.
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 provide commands and control modules coordinate electrical functions. A fault can cause warning lights, intermittent features, poor running or starting trouble. Ignoring it may affect connected systems, while replacing parts without testing adds needless cost.
We connect specialist diagnostic tools, read fault codes and live data, then test the relevant circuit. The evidence is documented, and we quote the failed sensor, switch, wiring or module before fitting parts.
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.
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's part lines, 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 attention is needed. Squealing, scraping, vibration or weaker braking can signal worn or damaged parts. Waiting can ruin usable discs, affect caliper movement and reduce braking performance.
We measure pad and disc wear, inspect the wear sensor and check that the caliper moves correctly. We document the measurements and quote only the worn or seized parts before work starts.
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.

Repair cost moves with the exact failed part, the extent of related damage and whether nearby wear is found during testing. The invoice statistic beside each repair is a useful guide, not a quote for your Lancer. We diagnose the car and confirm the price before work starts.
