Mazda CX-3 is a compact crossover that combines stylish design, reliable engines and good driving characteristics. However, like any car, it has a number of typical faults that owners encounter.

1. Engine and transmission

Increased oil consumption

Some owners of the 2.0-liter SkyActiv-G engine notice increased oil consumption after 50-100 thousand km.

Reason: design features of piston rings and high loads.

Solution: regular oil level monitoring, use of high-quality fuel and oil, preventive engine flushing.

Problems with automatic transmission (6-speed automatic transmission)

Slow shifting or jerking during acceleration.

Sometimes a jolt is felt when shifting from 2nd to 3rd gear.

Solution: update the automatic transmission firmware at the dealer, check the oil level and condition.

Reduced traction and unstable speed

May be due to clogged throttle valve or injectors.

Solution: clean the throttle and fuel system every 40-50 thousand km.

2. Electronics and electrics

Mazda Connect multimedia system glitches

Freezing, long startup or reboot of the system are possible.

Solution: update the multimedia firmware at an authorized dealer.

Problems with the rear view camera

Sometimes the image flickers or the camera stops working.

Cause: damage to the wiring in the area of the fifth door.

Solution: check the connectors, replace damaged sections of the wiring.

Burnt-out LEDs in the headlights

Front running lights (DRL) can fail after 3-5 years.

Solution: replace the DRL unit or the entire headlight.

i-Stop (start-stop) system errors

Often the system stops working, displaying a warning on the dashboard.

Cause: weak battery or failure in the system sensors.

Solution: replace the battery with an original analog with i-Stop support, diagnose the sensors.

3. Suspension and steering

Stiff suspension

Mazda CX-3 has a sports setting, which makes the suspension a bit stiff, especially on uneven roads.

Solution: reduce tire pressure to the recommended level or install alternative shock absorbers.

Knocking in the front suspension

Often appears after 50-70 thousand km.

Cause: wear of stabilizer struts or bushings.

Solution: replace stabilizer struts and bushings.

4. Corrosion and paintwork

Thin paintwork and chips

Chipped surfaces quickly appear on the hood and fenders, especially in winter.

Solution: apply anti-gravel film, treat with protective compounds.

Rear door corrosion

In some cases, traces of rust appear on the edge of the fifth door.

Solution: timely treatment with anti-corrosion, eliminate damage to the paintwork.

5. Brake system

Brake squeak

Even if the brake pads are in good condition, extraneous sounds may occur.

Solution: use alternative pads with a softer composition.

Rear brake disc wear

Due to the design features, the rear discs wear out faster than the front ones.

Solution: regular inspection and replacement if necessary.

Conclusion

Mazda CX-3 is a reliable crossover, but requires attention to electronics, suspension and paintwork. With timely maintenance and elimination of minor faults, the car will serve for a long time without serious problems.
