SUZUKI SX4 Common Problems & Reliability

Based on 1,749 MOT tests from 107 vehicles analysed by VehicleScore. The figures below describe that VehicleScore sample. Recurring issues seen in VehicleScore MOT data are not a claim that every SUZUKI SX4 has the same fault.

SUZUKI SX4's have a very good reliability rating of 611/999. The score was calculated from the average of every SUZUKI SX4 that has had a registered MOT.

We calculated all of the below figures by getting the score from each vehicle make/model/year/fuel, which are each calculated a score. We then generate the average score, taking into account factors such as mileage and emissions.

Also check BHP & performance, road tax, fuel economy, and CO2 emissions for the SUZUKI SX4.

Common SUZUKI SX4 MOT problems

These groups combine equivalent MOT comments, such as the same tyre note on different corners. Counts are comment occurrences in the sample, not a percentage of cars.

Tyre wear

VehicleScore MOT data includes 316 advisory comments and 26 failure comments in this group. Seen as both an advisory and a failure reason. These are comment occurrences, not a share of all cars.

These MOT comments record tyres that were worn, damaged, or close to the legal tread depth when the car was inspected.

What to inspect

Check the tread depth and look for uneven wear, cracking, or damage on all four tyres.

Example MOT wording: OFFSIDE FRONT TYRE WORN CLOSE TO LEGAL LIMIT/WORN ON EDGE (5.2.3 (E))

Corrosion

VehicleScore MOT data includes 274 advisory comments and 52 failure comments in this group. Seen as both an advisory and a failure reason. These are comment occurrences, not a share of all cars.

These MOT comments record corrosion the tester could see on the body or structure. Corrosion already named on a spring, brake, or other component is counted with that component.

What to inspect

Inspect the underside, sills, and subframe for heavy corrosion, especially where an advisory mentions it.

Example MOT wording: OFFSIDE FRONT BRAKE PIPE CORRODED, COVERED IN GREASE OR OTHER MATERIAL (1.1.11 (C))

Coil spring issues

VehicleScore MOT data includes 121 failure comments in this group. Seen mainly as a failure reason. These are comment occurrences, not a share of all cars.

These MOT comments record coil springs that were corroded, fractured, or otherwise defective. They are counted separately from shock absorbers.

What to inspect

Look for a broken or heavily corroded spring and compare the ride height on both sides.

Example MOT wording: OFFSIDE FRONT COIL SPRING FRACTURED OR BROKEN (5.3.1 (B) (I))

Brake pad wear

VehicleScore MOT data includes 37 advisory comments in this group. Seen mainly as an advisory. These are comment occurrences, not a share of all cars.

These MOT comments record brake pads that were worn or below the inspection limit.

What to inspect

Ask for recent pad replacement and look at the remaining pad thickness.

Example MOT wording: FRONT BRAKE PAD(S) WEARING THIN (1.1.13 (A) (II))

Oil leak

VehicleScore MOT data includes 32 advisory comments in this group. Seen mainly as an advisory. These are comment occurrences, not a share of all cars.

These MOT comments record an oil leak noted by the tester. Shock absorber misting is counted as a damper issue, not as an engine oil leak.

What to inspect

Look under the engine for fresh oil, and check the oil level.

Example MOT wording: OIL LEAK, BUT NOT EXCESSIVE (8.4.1 (A) (I))

Ball joint wear

VehicleScore MOT data includes 28 failure comments in this group. Seen mainly as a failure reason. These are comment occurrences, not a share of all cars.

These MOT comments record a worn or damaged ball joint. Track rod ends are counted with steering, not here.

What to inspect

Ask for the joint to be checked for play with the suspension loaded and unloaded.

Example MOT wording: NEARSIDE FRONT SUSPENSION ARM BALL JOINT EXCESSIVELY WORN (5.3.4 (A) (I))

Lamp and bulb faults

VehicleScore MOT data includes 27 failure comments in this group. Seen mainly as a failure reason. These are comment occurrences, not a share of all cars.

These MOT comments record a lamp or bulb other than a headlamp or indicator.

What to inspect

Switch on the side, brake, fog, and number-plate lamps.

Example MOT wording: OFFSIDE FRONT POSITION LAMP NOT WORKING (4.2.1 (A) (II))

Parking brake faults

VehicleScore MOT data includes 26 failure comments in this group. Seen mainly as a failure reason. These are comment occurrences, not a share of all cars.

These MOT comments record a parking brake that did not hold well enough or had a component defect.

What to inspect

Test that the parking brake holds the car on a slope and releases cleanly.

Example MOT wording: PARKING BRAKE EFFICIENCY BELOW REQUIREMENTS (1.4.2 (A) (I))

What to check when buying a used SUZUKI SX4

This is an inspection checklist based on MOT comments in the VehicleScore sample. It does not mean the car you are looking at has these defects.

Tyre wear. Check the tread depth and look for uneven wear, cracking, or damage on all four tyres.
Corrosion. Inspect the underside, sills, and subframe for heavy corrosion, especially where an advisory mentions it.
Coil spring issues. Look for a broken or heavily corroded spring and compare the ride height on both sides.
Brake pad wear. Ask for recent pad replacement and look at the remaining pad thickness.
Oil leak. Look under the engine for fresh oil, and check the oil level.
Ball joint wear. Ask for the joint to be checked for play with the suspension loaded and unloaded.
Lamp and bulb faults. Switch on the side, brake, fog, and number-plate lamps.
Parking brake faults. Test that the parking brake holds the car on a slope and releases cleanly.

Buying a SUZUKI SX4?

Common problems tell you what can affect SUZUKI SX4s generally. VehicleScore can check the history of the actual car you're considering.

Where does this data come from?

VehicleScore analyses MOT histories from vehicles in its own dataset. Sample sizes vary by model, and a small sample is labelled as such. MOT data records roadworthiness and inspection defects. It does not capture every mechanical or electronic problem a car can have, and a comment on one test is not proof that the model has an inherent fault.
