CarComplaints.com Notes: The 2010 Mazda CX-7 appears to share the same engine defects as the three previous model years: VVT/timing chain failure & turbo failure. The timing chain failure is especially bad with many cars requiring an engine replacement ($9,000+).
In 2011, Mazda began a "Special Service Program" that extended the warranty to 7 years/70,000 miles covering 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.

I have my Mazda 2010 CX7 on 3-11-2017. When the dealer give me to me. The Mazda have this. They star with the light on in air bag and other time. The other problem is when use the swith and put the light there change and I'm think there have problem electrical and in the rim. The Mazda running but they have a couple problem. And unknown situation the only fixed is the lower control arm. Because when am going ovethere they told me the only recall have is that want. The lower control arm.
I lost power to my 2010 Mazda CX7 while going 60 mp downhill in a mountain pass. My car went from 60 mp to 40 mp in about 30 seconds. I immediately pulled over as black smoke poured out of my tail pipe and had the car towed. My mechanic said the turbo was blown, which cause the car's oil to completely burn up, causing damage to the timing chain and engine. All of the oil was gone in a matter of a few miles. The car had been up to date on all maintenance. A new turbo and engine was needed on a car that had 74,000 miles on it.
It has been 1 year since the recall was made. But the parts were never available. I went through winter in Chicago feeling unsafe. I don't think they are replacing my lower control arm. They are postponing it to hope that I will forget about it.
Tcs and check engine light is on. The car does not have power even if the gas pedal is pressed all the way, the car moves only up to 5 miles per hour (RPM power). Vehicle loses throttle. Ac blows warm when tcs light is on. There is a white smoke from the exhaust. This usually happens after the car is parked for couple hours. The same issue occurs several times within a period of year and a half. My car was @ service shop more than 2 months. I contacted Mazda corporate office in several occasions and they are aware of the issues I have with the car, but they did not respond positively.

Sunroof shattered while driving on the highway at 60mph at 9:30am when I heard a loud crash on the roof of my car. I looked in my rear view mirror and saw many pieces of glass flying behind me. Thankfully, I had the shade drawn closed, otherwise, I would have been covered in a shower of glass. I managed to pull over and did not find any foreign objects or rocks (and saw no rocks bouncing in the street prior to this incident). The insurance company asked me what happened, but I had no explanation. It seems like the sunroof just exploded.
Sunroof shattered - I just got onto I-43 via the on ramp and my sunroof exploded and came down on me like a shower of glass. I was able to pull over. I immediately looked for any foreign debris but there was none. I drove home and called the car dealer (holiday in fond du lac wi). They said they never heard of a sunroof breaking because of the heat or anything like this and my extended warranty would not cover. I had it fixed and heard about this on the news two weeks later. My car is a 2010 Mazda CX7 in excellent condition. The cost to replace was $597.08 plus tax.
The turbocharger on this new vehicle failed while I was driving on the expressway, causing the vehicle to be unsafe and inoperable. Fortunately, I was able to get it off the road without an accident. The vehicle was not safe to leave in our attached garage overnight because of the risk of fire. It appears that there have been many, and repeated, problems with the turbocharger in these vehicles. To my knowledge, there has not been a recall.
