Most Common Mazda CX-7 Problems

Are you thinking about purchasing a new or used Mazda CX-7? If so, you are likely curious about what owners have liked about the vehicles, as well as what some of the main Mazda CX-7 problems they experienced were. Purchasing a new vehicle is a large investment, so we always recommend that buyers do their own research to determine if the vehicle they want is truly all that they think it is and if the needed maintenance fits into their budget. This will help you feel confident about your decision and set you up for a successful purchase. In this article, we will go over some of the most commonly reported Mazda CX-7 problems to help you make an informed purchase.

Top Mazda CX-7 Problems

1. Failure Turbocharger
   
   The turbocharger in the Mazda CX-7 is widely known to be prone to failure, resulting in a lack of power and acceleration. In addition to the lack of acceleration and power, another symptom of a failed turbo is white smoke coming from the exhaust. If you are experiencing these symptoms, you will likely have to replace the turbo to resolve the issue. 
2. Unpleasant Engine Noise
   
   One of the most reported Mazda CX-7 issues is regarding the worn timing chain causing unpleasant clanking noise from the front of the engine. To address this problem, you will generally have to replace the timing chain. 
3. Failed AC Compressor
   
   AC compressor failure is another common issue experienced by Mazda CX-7 owners. Reports state that the AC system began blowing warm air into the cabin of the car and in some cases, smoke would be coming from the engine. To resolve this failed AC compressor issue, you will have to have it replaced. Thankfully, Mazda has acknowledged the issue and has extended the warranty on these compressors. 
4. Transmission Problems
   
   Mazda CX-7 transmission problems often reveal themselves as grinding or being jumpy during accelerations, shifting delays, whistle-like noise coming from the engine, car shaking while driving, or a burning smell coming from underneath the hood. Since this is a common issue, Mazda recommends that owners should routinely have their transmission inspected for wear and tear. If you ignore these transmission problem symptoms, you might begin to notice your fuel economy decreasing or in some cases, be unable to drive your vehicle at all. 
5. CV Joint Problems
   
   Mazda CX-7 CV joint problems aren’t reported as frequently as the above Mazda CX 7 problems, but it is still an issue to look out for. The CV joints or the constant-velocity joints in your vehicle are responsible for transferring power from the transmission to its wheels while causing little to no friction. This allows you to turn the steering wheel and have the wheels respond smoothly. That said, if you believe that you have faulty CV joints, you should address the issue and have it looked at as soon as possible. Some symptoms to look out for are:
   1. Vibration while the vehicle is in motion
   2. Grease on wheels/tires 
   3. A knocking-like noise coming from the CV joint
   4. Loud popping or clicking sounds while turning the wheel
   5. Bouncing while driving on a flat road

Now that you know a bit more about the most commonly reported Mazda CX-7 problems, hopefully, you will be able to make a confident decision on whether or not it is the right vehicle for you. Regardless, most modern vehicles are reliable, so although no car is 100% perfect, if you follow the recommended maintenance required, you should have little to no issues with the car you choose.
