MAZDA CX 3 Common Problems & Reliability

Based on 1,187 MOT tests from 155 vehicles analysed by VehicleScore®. The figures below describe that VehicleScore® sample. Recurring issues seen in VehicleScore® MOT data are not a claim that every MAZDA CX 3 has the same fault.

MAZDA CX 3's have a extremely good reliability rating of 769/999. The score was calculated from the average of every MAZDA CX 3 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 MAZDA CX 3.

Common MAZDA CX 3 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 300 advisory comments and 12 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))

Brake pad wear

VehicleScore® MOT data includes 85 advisory comments and 14 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 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))

Corrosion

VehicleScore® MOT data includes 62 advisory comments in this group. Seen mainly as an advisory. 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))

Brake disc wear

VehicleScore® MOT data includes 35 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 discs that were worn, scored, pitted, or corroded.

What to inspect

Look at the disc faces for deep scoring, a lip at the edge, and corrosion.

Example MOT wording: REAR BRAKE DISC WORN, PITTED OR SCORED, BUT NOT SERIOUSLY WEAKENED (1.1.14 (A) (II))

Coil spring issues

VehicleScore® MOT data includes 10 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 REAR COIL SPRING FRACTURED OR BROKEN (5.3.1 (B) (I))

Windscreen damage

VehicleScore® MOT data includes 9 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 chips, cracks, or other windscreen damage in the driver’s view.

What to inspect

Look for chips and cracks, especially in the area swept by the wipers.

Example MOT wording: NEARSIDE WINDSCREEN WIPER DOES NOT CLEAR THE WINDSCREEN EFFECTIVELY (3.4 (B) (II))

Seatbelt faults

VehicleScore® MOT data includes 5 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 seatbelt that did not latch, retract, or meet the inspection standard.

What to inspect

Buckle every belt and confirm it locks and releases.

Example MOT wording: OFFSIDE REAR SEAT BELT RETRACTING MECHANISM DEFECTIVE (7.1.2 (E))

Engine warning lamp

VehicleScore® MOT data includes 3 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 an engine warning lamp that was on, or did not work, during the inspection.

What to inspect

Switch on the ignition and confirm the lamp comes on and then goes out. Ask what was diagnosed if it stayed on.

Example MOT wording: ENGINE MIL INOPERATIVE OR INDICATES A MALFUNCTION (8.2.2.2 (G))

What to check when buying a used MAZDA CX 3

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.
Brake pad wear. Ask for recent pad replacement and look at the remaining pad thickness.
Corrosion. Inspect the underside, sills, and subframe for heavy corrosion, especially where an advisory mentions it.
Brake disc wear. Look at the disc faces for deep scoring, a lip at the edge, and corrosion.
Coil spring issues. Look for a broken or heavily corroded spring and compare the ride height on both sides.
Windscreen damage. Look for chips and cracks, especially in the area swept by the wipers.
Seatbelt faults. Buckle every belt and confirm it locks and releases.
Engine warning lamp. Switch on the ignition and confirm the lamp comes on and then goes out. Ask what was diagnosed if it stayed on.

Buying a MAZDA CX 3?

Common problems tell you what can affect MAZDA CX 3s 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.
