What each repair involves on the GLA, 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.
Brake pads, discs and wear sensors on the GLA
33% of the GLA registrations in our records had at least one invoice involving this work (36 of 109, 40 invoices in all). On the bill, this item typically came to about $750 (middle half $700 to $1,450, 30 recent priced bills, GST included; other work on the same bill is not counted).
Brake pads create friction against the discs to slow the car, while wear sensors flag low friction material. You may notice squealing, vibration, weak stopping feel or a warning on the dash. Delaying inspection can damage the discs, strain related hardware and raise the repair cost.
We use XENTRY to read relevant faults, then measure the pads and discs and inspect the wear sensors. We document what is worn and give you an honest quote for the required 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.

Battery replacement on the GLA
29% of the GLA registrations in our records had at least one invoice involving this work (32 of 109, 36 invoices in all). On the bill, this item typically came to about $350 (33 recent priced bills, GST included; other work on the same bill is not counted).
The battery supplies power for starting and supports the electrical systems when demand changes. Slow cranking, dim lights, warning messages or electronics that behave oddly can point to low battery output or a charging fault. Ignoring the cause can leave the car stranded and turn a battery concern into a wider electrical repair.
We run battery and charging-system tests, check the terminals and use XENTRY to review voltage-related faults. The results are documented, then we give you an honest quote for the battery, connection or charging part that needs attention before work starts.
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 GLA
29% of the GLA registrations in our records had at least one invoice involving this work (32 of 109, 36 invoices in all). On the bill, this item typically came to about $250 (34 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 fluid may be accompanied by rough engagement, hesitant shifts or noise. Leaving contaminated fluid or an active leak unchecked can accelerate internal wear and make the repair more involved.
We read gearbox faults with XENTRY, inspect for leaks and assess the fluid condition before recommending a change. We document whether the oil service or a failed seal is required and provide an honest quote before work 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.

Cooling-system leaks and failed parts on the GLA
26% of the GLA registrations in our records had at least one invoice involving this work (28 of 109, 36 invoices in all). On the bill, this item typically came to about $450 (middle half $350 to $700, 33 recent priced bills, GST included; other work on the same bill is not counted).
Coolant carries heat away from the engine, while the pump, thermostat and radiator control its flow and temperature. A warning, rising temperature, sweet smell or damp patch can signal a leak or circulation problem. Continuing to drive can cause overheating, damage nearby components and turn a contained repair into major engine work.
We pressure-test the cooling system, add tracing dye when needed and use XENTRY to check temperature data and related faults. We document the leak source and give you an honest quote for the failed cooling part before work starts.
When to inspect or replace: Water pumps, thermostats, radiators and hoses are inspected and pressure-tested and replaced when a fault is confirmed; some engines also list a scheduled water-pump replacement, which we check for your car. Coolant itself is changed on the maker's schedule for your engine.
Maintenance and early warning signs: Top up only with the specified coolant, and stop as soon as a temperature warning appears. Early signs: a sweet smell, a coolant level that keeps dropping, a wet patch, a temperature gauge climbing in traffic.

Gasket, seal, cover and housing oil leaks on the GLA
17% of the GLA registrations in our records had at least one invoice involving this work (18 of 109, 18 invoices in all). On the bill, this item typically came to about $300 (middle half $250 to $300, 17 recent priced bills, GST included; other work on the same bill is not counted).
Engine oil protects moving parts and must stay inside a sealed lubrication system. Burning smells, drops under the car, smoke or a falling oil level can point to a leaking gasket, seal, cover or housing. A leak left alone can contaminate belts and mounts, lower the oil level and widen the repair.
We clean the affected area, trace oil from the highest wet point and use XENTRY where related readings or faults help the diagnosis. Our documented findings identify the failed seal or housing, followed by an honest quote before work starts.
When to inspect or replace: Checked at every service and repaired according to the source and severity found, from a weeping seal to a housing. No age makes a leak due.
Maintenance and early warning signs: Change the oil on time to the maker's specification, and fix small weeps before they reach belts, mountings and electrical parts. Early signs: drips under the car, a burning smell after driving, a falling oil level.

Sensor, switch and control-module faults on the GLA
16% of the GLA registrations in our records had at least one invoice involving this work (17 of 109, 17 invoices in all). On the bill, this item typically came to about $200 (middle half $150 to $200, 14 recent priced bills, GST included; other work on the same bill is not counted).
Sensors report operating conditions, switches send commands and control modules coordinate electronic functions. Warning lights, intermittent features, erratic readings or a system that stops responding can all start in this chain. Replacing parts without testing can miss a wiring or power-supply fault and add needless cost.
We scan the relevant systems with XENTRY, compare live data and test power, ground and signal paths. We record the evidence and give you an honest quote for the faulty sensor, switch, wiring section or module before work starts.
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 calipers, hoses and anti-lock faults on the GLA
11% of the GLA registrations in our records had at least one invoice involving this work (12 of 109, 16 invoices in all). On the bill, this item typically came to about $300 (middle half $200 to $350, 11 recent priced bills, GST included; other work on the same bill is not counted).
Brake fluid carries pedal force to the calipers, while the anti-lock system helps retain steering control under hard braking. A soft pedal, pulling, dragging, warning light or uneven braking needs prompt attention. Waiting can damage pads and discs, overheat a wheel or reduce braking control.
We inspect the hydraulic circuit, check caliper movement and hose condition, then use XENTRY to test anti-lock faults and wheel-speed signals. We document the failed caliper, hose, sensor or pump and present an honest quote before work starts.
When to inspect or replace: Calipers, hoses and ABS parts are diagnosed and replaced on a confirmed fault. Brake fluid is changed on the time schedule for your car, because it absorbs moisture.
Maintenance and early warning signs: Change brake fluid on schedule, have the caliper sliders serviced at pad changes, and act on a pulling or dragging brake at once. Early signs: a soft or long pedal, pulling to one side, a hot wheel after driving, an ABS warning.

Spark plugs and ignition coils on the GLA
10% of the GLA registrations in our records had at least one invoice involving this work (11 of 109, 11 invoices in all). On the bill, this item typically came to about $200 (9 recent priced bills, GST included; other work on the same bill is not counted).
Spark plugs ignite the air and fuel mixture, while ignition coils provide the voltage needed for a clean spark. Rough idle, hesitation, poor response or a flashing engine light can indicate a misfire. Driving with a persistent misfire can damage the exhaust catalyst and turn a small ignition repair into a larger job.
We use XENTRY to identify the misfiring cylinder, inspect the plugs and perform a coil substitution test where suitable. The diagnosis is documented, and we give you an honest quote for the required plugs or failed coil 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.

Engine and gearbox mounts on the GLA
8% of the GLA registrations in our records had at least one invoice involving this work (9 of 109, 9 invoices in all). On the bill, this item typically came to about $1,050 (middle half $1,050 to $1,300, 9 recent priced bills, GST included; other work on the same bill is not counted).
Engine and gearbox mounts hold the powertrain in position while isolating vibration from the cabin. Thumping during engagement, shaking at idle or vibration under load can point to collapsed rubber or a failed hydraulic mount. Waiting can increase movement and strain hoses, wiring or exhaust connections.
We road-test the car, inspect each mounting under load and use XENTRY to rule out running faults that can mimic mount vibration. We show you the documented findings and quote honestly for the responsible engine mount, gearbox mount or related part before work starts.
When to inspect or replace: Mountings are inspected under load and replaced when a mount is confirmed split, collapsed or leaking. Vibration alone is not a diagnosis, because a misfire feels similar.
Maintenance and early warning signs: Accelerate and brake smoothly, especially between traffic lights, do not snap the car into gear at high revs, and fix oil leaks that soften the rubber. Early signs: a clunk when selecting drive, shake at idle, engine movement under load.

The total depends on whether the visit is routine maintenance, a targeted component repair or work across related systems. Invoice patterns are useful guidance, but the condition of your GLA decides the actual scope. We inspect it, explain what is needed and give you an honest quote before work starts.
