Now narrow it to the engine

A 1.8 and a 2.4 of the same car do not fail the same way, so the faults below narrow to the engine as well as the year. Free, no account needed.

The checks worth doing on a Mazda Mazda5 before you hand over any money. Every documented fault is listed below, each with its own page.

• Serious issue

  Obtain timing belt records and confirm interval compliance: typically 100,000 km or 10 years for FS-ZE and LF-VE.

  See why

  Timing belt failure — interference engine (FS-ZE / LF-VE)

  The CP Premacy uses the FS-ZE 1.8 and the CW Premacy uses the LF-VE 2.0, both interference-design engines. Belt snap causes immediate valve-to-piston contact and engine write-off. NZ examples are predominantly JDM imports and arrive with Japanese service records that may not indicate interval clearly for local buyers. The belt is concealed behind covers, making visual inspection without partial disassembly impractical.

  What you would notice

  • No advance warning before catastrophic belt failure
  • Tensioner rattle or squealing may precede failure
  • Japanese-only service documentation making interval verification difficult

  Typically $400–$650 to put right.

• Serious issue

  Start the engine from cold and listen for a rattling or slapping noise from the front of the engine that should settle within 3–5 seconds.

  See why

  LF-VD Timing Chain Guide and Tensioner Wear

  The LF-VD 2.0-litre engine uses a simplex timing chain with plastic guide rails and a hydraulic tensioner. At high mileage, typically above 150,000 km, the plastic guide material wears and cracks, and the tensioner piston loses sealing pressure — particularly if oil change intervals have been extended. The result is chain slap noise on cold start that can progress to chain skip and valve-to-piston contact if neglected. NZ-imported units frequently arrive with undisclosed mileage or unknown service histories, increasing the incidence.

  What you would notice

  • Metallic rattling noise from the front of the engine on cold start, lasting more than a few seconds before quieting
  • Check engine light with camshaft-to-crankshaft timing correlation fault codes P0016 or P0017

  Typically $900–$2,200 to put right.

• Costly issue

  For hydraulic systems: inspect the steering rack boots for power steering fluid contamination and the reservoir for low fluid level.

  See why

  Electric Power Steering Rack Seal and Fluid Leak

  Premacy CR models fitted with hydraulic-assist power steering develop weeping and then active leaks at the inner rack seals and the high-pressure hose banjo fittings. The rack pinion seal fails due to age hardening of the rubber compounds, and the power steering fluid contaminates the subframe and surrounding chassis. CW models with electric power steering (EPS) develop a different failure: the motor control unit overheats or develops solder joint failures, triggering a loss-of-assist condition. Both variants generate a dashboard EPS or PS warning lamp.

  What you would notice

  • Power steering fluid seeping from the steering rack area, leaving oily residue on the subframe and inner guards
  • EPS or PS warning light illuminating on the instrument cluster, accompanied by heavy or intermittently absent steering assist

  Typically $800–$2,800 to put right.

• Costly issue

  Test drive at 80-100 km/h with very light throttle and feel for rhythmic vibration.

  See why

  Automatic Transmission Torque Converter Shudder

  4-speed automatic torque converter develops lock-up clutch shudder under light throttle at highway cruise.

  What you would notice

  • Rhythmic vibration at highway speed under light throttle
  • Shudder clears under firm acceleration

  Typically $400–$2,500 to put right.

• Costly issue

  Cold-start from overnight cold and listen for rattle from engine front.

  See why

  L3-VE Timing Chain Tensioner Rattle

  The CR Premacy L3-VE 2.3 timing chain tensioner produces a metallic rattle on cold start from oil pressure lag. Persistent rattle beyond 10 seconds indicates worn tensioner or guides.

  What you would notice

  • Metallic rattle from engine front on cold start
  • Rattle persisting beyond 10 seconds or at operating temperature

  Typically $600–$1,800 to put right.

• Costly issue

  Cycle the sliding door three to four times using the power button and manually.

  See why

  Power sliding door cable fraying and roller failure

  The CP and CW Premacy sliding door operates via a cable-and-roller mechanism that stretches, frays and derails with age and use. The door may hesitate, reverse before latching, slam shut on a slope or trigger a continuous power-door warning light. Upper and lower track rollers corrode on older NZ examples, binding the door and accelerating cable wear. The failure mode ranges from inconvenient to a safety hazard if the door cannot be secured.

  What you would notice

  • Sliding door hesitates, reverses mid-travel or fails to latch
  • Power door warning lamp illuminated on instrument cluster
  • Door travel is jerky or makes grinding noise in track
  • Door rolls shut under gravity on a slope

  Typically $400–$900 to put right.
