This is the series most affected by chain problems according to Wikipedia; it is only worth considering with an oil service history and a timing check.[2][3]
Faults that affect 2007 cars
- Critical severityFrequency: CommonTimingTiming chain stretch and VVT actuator failure on the 2.3 DISI TurboThe 2.3 DISI Turbo's timing chain and its tensioner wear sooner than expected, especially on pre-2010 units: a rattle when cold is the warning, and if it fails it can damage the engine.Appears at around 100,000 km
- High severityFrequency: CommonTurboPremature turbocharger wear from poor lubrication on the 2.3 DISI TurboThe 2.3 DISI Turbo's turbo, with faults documented mainly on the CX-7, wears out through poor lubrication and causes blue smoke, loss of power and oil consumption; replacing it costs around €2,200 in Spain.Repair (garage): €2,200Appears at around 100,000 km
- Medium severityFrequency: OccasionalLubricationOil consumption and sludge in the 2.3 DISI Turbo engineThe 2.3 DISI Turbo can burn oil and build up sludge if service intervals are stretched; the sludge blocks the turbo's passages and speeds up wear on the turbo and the timing.
Faults outside the engine in the 2007 Mazda CX-7
- Critical severityFrequency: OccasionalSuspensionLower front suspension ball joint that can seize or break through corrosionYes: a recall covers CX-7s built between May 2007 and August 2012 because water can get into the lower front suspension ball joint and cause corrosion and seizing; in the worst case the ball joint breaks and control of the steering can be lost. The complete lower arm is replaced.
- Critical severityFrequency: OccasionalAirbags and safetyTakata recall: the passenger airbag inflator can rupture on deploymentYes: Safety Gate lists an alert on Mazda CX-7s built between 1 January 2007 and 12 June 2009 because the ammonium nitrate propellant in the front passenger airbag inflator can degrade with heat and humidity, rupture the inflator on deployment and throw out metal fragments.
- Medium severityFrequency: OccasionalBrakesPremature wear of the brake discs and padsThe 2015 DEKRA report, covered by Autofácil, points to discs and pads with premature wear and poor braking power as problems of the Mazda CX-7 (2007-2011) after 100,000 km, within a 13.4% rate of serious faults compared with the 10.3% SUV average.
- Medium severityFrequency: OccasionalSteeringPlay in the steering ball jointsThe 2015 DEKRA report, covered by Autofácil, cites play in the steering ball joints among the problems of the Mazda CX-7 (2007-2011) after 100,000 km. It is not the same fault as the lower front suspension ball joint campaign, although both are worth checking on a car of that era.
- Low severityFrequency: RareTyres and wheelsElectronic faults in the tyre pressure monitoring systemThe 2015 DEKRA report, covered by Autofácil, mentions some electronic faults in the tyre pressure monitoring of the Mazda CX-7 (2007-2011). The source does not explain whether the wheel sensors or the control unit are failing.
