2009 Mazda CX-7

The 2009 Mazda CX-7 is a compact crossover SUV that offered sporty handling and distinctive styling. The standard engine was a 2.3-liter turbocharged four-cylinder producing 244 horsepower and 258 lb-ft of torque. A non-turbo 2.5-liter four-cylinder engine option producing 161 horsepower and 161 lb-ft of torque became available mid-year. The 2.3L turbo engine was paired with a 6-speed automatic transmission, while the 2.5L engine was paired with a 5-speed automatic transmission. Owners often appreciated the CX-7’s sharp steering and responsive engine (especially the turbo model), but some disliked the turbo engine’s fuel economy and potential reliability issues.

Summary

The 2009 Mazda CX-7 presents a mixed bag for potential buyers. While it offers sporty handling and attractive styling, it’s crucial to be aware of potential engine issues with the turbocharged 2.3L variant, particularly turbocharger and timing chain problems, which can be expensive to repair. Suspension and electrical issues are also common, but generally less severe. Overall, pre-purchase inspection is critical, especially regarding oil maintenance history for the 2.3L turbo engine. Due to the age of the vehicle, repairs may be more frequent and finding parts may be more challenging, potentially increasing the overall cost of ownership.
