CarComplaints.com Notes: The 2007 Mazda CX-7 has numerous reports filed with the NHTSA about engine & A/C problems.
Owners report problems with the 2007 CX-7's Variable Valve Timing (VVT) & timing chain failing, causing major damage to the engine — Mazda uses an interference design so typically the valves are bent & the entire engine needs to be replaced. Mazda dealers typically quote $9,000 for an engine replacement.
There is also a trend of the turbo failing at low mileage.
Finally for the 2007 CX-7 there is a clear pattern of A/C compressor failure at relatively low mileage. Owners report smoke & occasionally the serpentine belt catches fire when the A/C compressor clutch seizes while driving. Mazda extended the A/C warranty to 60,000 miles, however many owners report their A/C compressor failed very soon after the 60k mark.
In 2011, Mazda began a "Special Service Program" that extended the warranty to 7 years/70,000 miles covering turbocharger oil leaks & excessive timing chain noise — an early sign of timing chain failure. However coverage under the program requires perfect documentation of all required maintenance with other stipulations. Buyer beware.
Low beam headlights on this vehicle are extremely poor and they are so dull that it is difficult to drive at night. When I compare the low beam halogen projectors on other makes of vehicles that I have driven, they consistently perform far better than those on the Mazda. I felt that the lights were sub par from the time I bought the vehicle from new, but they have gotten worse over time. Specifically the illumination of the road surface, the focus and the distance of the light all appear to be very poor. It is just difficult to see at night.
I suspect that the problem is in the design and construction of the lights because as I mentioned, I noticed this problem when the car was new. So this is not a problem of old lights on an old car. I even mentioned it to the dealership during a service and they checked the aim of the lights and said that they were working perfectly. Having seen other complaints from other owners and drivers of this vehicle, I am now convinced that this is a problem that Mazda should take responsibility for. Headlights are there to enable drivers to see and be seen under most road conditions. The 2010 Mazda Cx-7 headlights simply fail to achieve this.
This is clearly a case of form over function, but in this case it had led to a serious safety concern. I have just replaced both complete headlight Assembly and all the bulbs with premium bulbs and it is still worthless i passed some workers on the road last night wearing reflective jackets and I still could not see them without turning on my brights,these lights are the worst ever
