Mazda CX-9 Common Problems
The Mazda CX-9 crossover SUV combines the signature handling characteristics that Mazdas are widely known for and the lavish, spacious interior of an SUV. Sharing the basic architecture and the 273-horsepower 3.7-liter V6 engine of the Ford Edge crossover, the CX-9 stands on its own with better superb driving dynamics and a more athletic driving feel despite having a larger profile than its competitors.
The CX-9 is a well-designed automobile that comes in three types of trim and is available in 4WD and AWD configurations. But in spite of its improved design, it still has been known to have a host of problems and flaws, particularly with more recent models. The following are some of the most common of these Mazda CX-9 problems that have been reported by owners.
The 2010 models of the CX-9 have been reported by owners to experience premature brake wear, often signaled with excessive noise when braking and a sharp drop in braking response. The root of the problem is mostly due to the freezing of the brake calipers, causing the pads to remain constantly in contact with the rotors. Because of the danger imposed of this fault, it is highly recommended to replace the brake rotors, calipers, and pads as soon as possible.
Another noise-related problem that is found in 2007-2009 CX-9 models is that of a chirping or squeaking sound located in the front of the vehicle. The sound is particularly noticeable when the vehicle is going over bumps and other types of rough terrain at low speeds. Such problems often occur due to faulty strut mounts, which will require replacement.
The sunroof drain of the CX-9 is quite prone to clogging, leading to water dripping into the windshield, the dashboard, and into the car’s body control module BCM itself. This can lead to a variety of further problems, including alarms going off randomly; the parking brake light, TCS lights, and other instrument lights turning on and off; and the A/C unit functioning intermittently. A water-damaged BCM must often be replaced, although such cases can be prevented by regularly checking the sunroof drain for debris and declogging it when necessary.
