2018 Mazda CX-5 Reliability Score & Common Problems

Owners of the 2018 Mazda CX-5 frequently report issues with the infotainment system, often describing a "ghost touch" phenomenon where the screen registers inputs without being touched, leading to random phone calls, radio station changes, and unexpected volume adjustments. These issues are noted to be distracting and potentially hazardous while driving. Complaints also mention the vehicle stalling unexpectedly, sometimes linked to infotainment malfunctions, which can occur at various mileages and have been reported to cause dangerous situations in traffic. Additionally, some owners describe problems with the vehicle's electronic parking brake engaging unexpectedly. While one complaint involves a fire, most reports focus on electronic malfunctions that impact driving safety.

Owners of the 2018 Mazda CX-5 frequently report issues related to the fuel system, particularly concerning fuel pump failures and stalling. Symptoms commonly described include hesitation during acceleration, fluctuating fuel gauges, and vehicles stalling or losing power while driving, sometimes with the check engine light illuminated. These issues are often reported at mileages ranging from approximately 15,000 to 82,000 miles. Many owners mention receiving recall notifications but experiencing delays in obtaining necessary repair parts, which are often unavailable, leading to extended periods without resolution. While no crashes or fires are reported, the stalling and loss of power could have implications for vehicle control and safety.

Owners of the 2018 Mazda CX-5 frequently report issues with the brake system, particularly involving the Smart City Brake Support (SCBS) feature and caliper malfunctions. Complaints often describe the SCBS system engaging unnecessarily, causing sudden and severe braking, which has led to near-misses and three reported crashes. Additionally, several owners mention calipers sticking or seizing, leading to premature wear of brake components. These issues are reported at various mileage ranges, with some occurring as early as 1,500 miles. Safety implications include loss of control and increased risk of rear-end collisions due to unexpected braking. Potential buyers should be aware of these patterns, as they may affect the vehicle's reliability and safety.

Owners of the 2018 Mazda CX-5 frequently report issues with the Soul Red Crystal paint chipping excessively. Complaints commonly describe paint chips forming on the hood, doors, and side panels, often within a few months of purchase and at low mileages, such as under 7,000 miles. Many owners suggest that the paint appears thin and not well-bonded to the metal, with some noting that even small road debris can cause significant chipping. There are no reports of safety implications such as crashes or loss of control. Used car buyers should be aware of potential paint durability issues, especially with vehicles featuring the Soul Red Crystal color option.

Owners of the 2018 Mazda CX-5 report issues primarily related to airbag deployment and warning systems. Complaints frequently mention unintended airbag deployments, both during and after minor impacts, with some cases resulting in crashes or injuries.

Additionally, there are instances of unintended acceleration leading to crashes, although airbags did not always deploy in these situations. Prospective buyers should be aware of these potential safety concerns, especially regarding airbag functionality and unintended acceleration.

Owners of the 2018 Mazda CX-5 report issues with vehicle speed control, particularly involving unintended acceleration and stalling. Several complaints describe incidents where the vehicle suddenly accelerates while parking at low speeds, leading to crashes into fixed objects or other vehicles.
