What to look out for

The checks worth doing on a Mazda CX-50 before you hand over any money. Every documented fault is listed below, each with its own page.

  • Serious issue

    Start the car and check that the ABS and brake warning lights go out after a few seconds.

    See why

    ABS hydraulic control unit may be damaged, reducing braking (Recall 23V-275)

    Mazda recalled some 2023 CX-50s, along with 2022-2023 CX-30s, because the ABS hydraulic control unit may have been damaged in production, which can reduce braking ability and lengthen stopping distances. The fix is an inspection and a new hydraulic unit where needed. This is a low-volume recall, but on a grey import it may not have been done and an ABS unit is costly to replace locally.

    What you would notice

    • ABS or brake warning light on the dash
    • Brake pedal feels soft or travels further than normal
    • ABS pulses or buzzes at low speed when it should not
    • Longer stopping distance

    Typically $1,800–$4,000 to put right.

  • Serious issue

    Look at both front wheels from in front of the car: they should sit straight and evenly in the wheel arches.

    See why

    Front suspension bolts may not be tightened, risk of wheel detachment (Recall 25V-737)

    Mazda recalled a batch of 2025 CX-50 and CX-50 Hybrid vehicles because front suspension fastener bolts may not have been tightened properly at the factory. A loose bolt can let a suspension part or even a wheel come away, causing loss of control. The fix is an inspection, with bolts replaced and tightened as needed. The CX-50 is built for North America and was not sold new in NZ, so a grey import may never have been inspected, and Mazda NZ is not obliged to carry out a US recall.

    What you would notice

    • Clunk or knock from the front when going over bumps or braking
    • Steering pulls or feels vague
    • Front wheel looks tilted or sits wrong in the arch
    • Uneven front tyre wear

    Typically $100–$1,200 to put right.

  • Serious issue

    Ask for the US service history or a recall printout showing recall 25V-413 (airbag module software update) was completed.

    See why

    Airbag control module software may make the airbags deploy improperly (some 2025 CX-50s, recall 25V-413, check VIN)

    On some 2025 Mazda CX-50s, including hybrids, the airbag restraint control module software may be incorrectly configured, so an airbag may not deploy correctly in a crash. Mazda recalled affected cars in the US under NHTSA recall 25V-413 and dealers update the software free. The CX-50 was not sold new in NZ or Australia, so an imported car needs a check that the update was done before or after import.

    What you would notice

    • Usually no symptom before a crash
    • Airbag warning light may or may not show

    Typically $0–$400 to put right.

  • Costly issue

    If the car has a tow hitch, grab the tow ball or receiver and push and pull it hard: it should not move or knock.

    See why

    Trailer hitch bolts can loosen and the hitch can come off (2024-2025 CX-50 with Mazda accessory tow hitch, recall 25V-167)

    On 2024 and 2025 Mazda CX-50s fitted with a Mazda Genuine Accessory trailer hitch, the bolts holding the hitch assembly to the body may loosen. The hitch can then separate from the car while towing or even in normal driving. Mazda recalled affected cars in the US under NHTSA recall 25V-167 and dealers tighten the bolts free. Cars without a hitch are not affected.

    What you would notice

    • Clunk or rattle from the rear when towing or over bumps
    • Hitch moves when pushed by hand

    Typically $0–$300 to put right.

  • Costly issue

    Start the car and watch the dash: after a few seconds no driver assist, smart brake support or lane keep warning should remain.

    See why

    Forward sensing camera fault disables auto emergency braking and lane keep (Recall 24V-649)

    A small number of 2025 CX-50s, along with some 2024 Mazda3 and CX-30s, were recalled because the forward sensing camera behind the windscreen can malfunction. When it does, automatic emergency braking and lane keep assist stop working and the automatic high beam no longer dips for oncoming traffic. The fix is an inspection and a new camera if needed. On a grey import this may not have been done, and a replacement camera plus windscreen camera calibration is expensive if paid locally.

    What you would notice

    • Warning message that the smart brake or lane keep system is unavailable
    • Driver assist warning lights stay on after start up
    • Automatic high beam does not dip for oncoming cars
    • Lane keep assist does nothing when drifting over lines

    Typically $1,500–$3,500 to put right.

01Airbag control module software may make the airbags deploy improperly (some 2025 CX-50s, recall 25V-413, check VIN)

Ask for the US service history or a recall printout showing recall 25V-413 (airbag module software update) was completed.2025Electrical
RareElectrical $0–$400 to fix

Can't confirm for this car

On some 2025 Mazda CX-50s, including hybrids, the airbag restraint control module software may be incorrectly configured, so an airbag may not deploy correctly in a crash. Mazda recalled affected cars in the US under NHTSA recall 25V-413 and dealers update the software free. The CX-50 was not sold new in NZ or Australia, so an imported car needs a check that the update was done before or after import.

Symptoms to notice

  • Usually no symptom before a crash
  • Airbag warning light may or may not show

What to check

  1. Ask for the US service history or a recall printout showing recall 25V-413 (airbag module software update) was completed.
  2. Check the airbag warning light comes on at start-up and then goes out.
  3. If a workshop inspection is possible: have a Mazda dealer or diagnostic workshop read the airbag module software level against the recall.

Where to look: Airbag restraint control module, centre of the car under the dash

Ask the seller

  • “Was recall 25V-413 done in the US before export?”
  • “Do you have the import paperwork and recall history?”

02Forward sensing camera fault disables auto emergency braking and lane keep (Recall 24V-649)

Start the car and watch the dash: after a few seconds no driver assist, smart brake support or lane keep warning should remain.2025Electrical
RareElectrical $1,500–$3,500 to fix

  • Driver assist warning lights stay on after start up
  • Automatic high beam does not dip for oncoming cars
  • Lane keep assist does nothing when drifting over lines

What to check

Start the car and watch the dash: after a few seconds no driver assist, smart brake support or lane keep warning should remain. Look at the camera housing at the top centre of the windscreen for cracks, stone chips in front of the lens or signs the screen has been replaced. On the test drive turn on lane keep assist and check it responds, and check the driver assist settings screen does not show a system fault. Enter the VIN into the NHTSA recall lookup on your phone to see if recall 24V-649 (Mazda 6824H) is open. If a workshop inspection is possible: scan the forward sensing camera module for fault codes and confirm the camera calibration is current.

Where to look: Forward sensing camera at the top centre of the windscreen behind the rear view mirror

Ask the seller

  • “Has the forward camera recall been checked?”
  • “Has the windscreen ever been replaced, and was the camera recalibrated?”
  • “Have any driver assist warnings come up?”

01ABS hydraulic control unit may be damaged, reducing braking (Recall 23V-275)

Start the car and check that the ABS and brake warning lights go out after a few seconds.2023Brakes
RareBrakes $1,800–$4,000 to fix

Can't confirm for this car

Mazda recalled some 2023 CX-50s, along with 2022-2023 CX-30s, because the ABS hydraulic control unit may have been damaged in production, which can reduce braking ability and lengthen stopping distances. The fix is an inspection and a new hydraulic unit where needed. This is a low-volume recall, but on a grey import it may not have been done and an ABS unit is costly to replace locally.

Symptoms to notice

  • ABS or brake warning light on the dash
  • Brake pedal feels soft or travels further than normal
  • ABS pulses or buzzes at low speed when it should not
  • Longer stopping distance

What to check

Start the car and check that the ABS and brake warning lights go out after a few seconds. With the engine running, press and hold the brake pedal firmly for 20 seconds and check it stays firm. On the test drive brake firmly from 50 km/h on a clear road and feel for a soft pedal, pulling, or ABS pulsing on a dry surface. Enter the VIN into the NHTSA recall lookup on your phone to see if recall 23V-275 (Mazda 5823D) is open. If a workshop inspection is possible: scan the ABS module for fault codes and check the hydraulic unit part number against the recall.

Where to look: ABS hydraulic control unit in the engine bay, connected to the brake lines

Ask the seller

  • “Has the ABS unit recall been checked or done?”
  • “Has the ABS or brake warning light ever come on?”
  • “Has the car had any brake work since import?”

02Front suspension bolts may not be tightened, risk of wheel detachment (Recall 25V-737)

Look at both front wheels from in front of the car: they should sit straight and evenly in the wheel arches.2025Suspension
RareSuspension $100–$1,200 to fix

  • Steering pulls or feels vague
  • Front wheel looks tilted or sits wrong in the arch
  • Uneven front tyre wear

What to check

Look at both front wheels from in front of the car: they should sit straight and evenly in the wheel arches. Check the front tyres for uneven wear on the inner or outer edges. On the test drive drive slowly over speed bumps and brake firmly, listening for a clunk from the front, and check the car tracks straight with the wheel centred. Enter the VIN into the NHTSA recall lookup on your phone to see if recall 25V-737 (Mazda 7925J) is open, and ask for proof of the inspection. If a workshop inspection is possible: on a hoist, check the front lower arm, subframe and knuckle bolts for correct torque and witness marks, and check wheel alignment.

Where to look: Front suspension, lower arms, knuckles and subframe bolts behind the front wheels

Ask the seller

  • “Has the front suspension bolt recall been checked, and is there paperwork?”
  • “Have you noticed any clunking from the front?”
  • “Has the car had a wheel alignment since import?”

03Trailer hitch bolts can loosen and the hitch can come off (2024-2025 CX-50 with Mazda accessory tow hitch, recall 25V-167)

If the car has a tow hitch, grab the tow ball or receiver and push and pull it hard: it should not move or knock.2024–2025Body & Rust
OccasionalBody & Rust $0–$300 to fix

Can't confirm for this car

On 2024 and 2025 Mazda CX-50s fitted with a Mazda Genuine Accessory trailer hitch, the bolts holding the hitch assembly to the body may loosen.

Cars without a hitch are not affected.

Symptoms to notice

  • Clunk or rattle from the rear when towing or over bumps
  • Hitch moves when pushed by hand

What to check

If the car has a tow hitch, grab the tow ball or receiver and push and pull it hard: it should not move or knock. Look at the bolt heads around the hitch mounting for rust marks or shiny witness lines that show movement. Ask for proof recall 25V-167 was done. If a workshop inspection is possible: have the hitch bolts torque-checked on a hoist.

Where to look: Rear underbody, trailer hitch mounting bolts

Ask the seller

  • “Was the hitch fitted by Mazda, and was recall 25V-167 done?”
  • “Has the car been used for towing?”
