Mazda CX-7 grinding brakes problems

Filed Oct 20, 2026 · Brakes, Suspension · TX

Ball joints , control arms , wheel barrings broke into pieces. Tire was angled in grinding on the brakes and rotor. It was bought at a auction from a previous auction buyer. I bought a new frame for the back due to it being bent. I also replaced the exhaust pipe it was cut into pieces. I was very concerned with the lower control arm parts being warn out. The dangers of the ball joints or the barring falling apart would have left me in a dier tragedy. I did have a mechanic replace the parts. He did damage to them so I had to uninstall parts and assemble them as precise as should be. I also had to leave my car there was no way I was able to move it without a part busting off. It is being maintained part by part . Its a hassle . I do believe parts were being swapped without me knowing. That is very concerning . I also replaced the tire .

Vehicle stalled in sams club parking lot. It did restart but started making a rubbing or grinding noise. Turns out the AC compressor locked up. According to internet postings it is a known issue with 2007/2008 models. Apparently it was addressed for 2009 model. I've ran 7 or 8 vehicles for 200,000 plus miles and have yet to have a compressor go out until this know anomaly. Where is the resolution from mazda?

I noticed a "rubbing: sound, or a sound in the suspension or steering that would lead me to think it needed a "lube job", but newer vehicles no long need to be greased so I took it to the dealer. The sound occurred most notably at low speed while turning slowly, many times while backing up and turning, it sounded "dry" and labored, not a squealing or squeaky sound. But I could not reproduce the noise at the dealership, despite multiple trips and having the mechanic sit in the vehicle with me. Finally they replaced the "strut bearings" in 2013, though I had never heard of this part before. They were certain this would correct the problem but it did not. My last trip to the dealer in oct. 2014 LED them to think the struts needed replacing along with the strut bearings, though the latter was still under warranty. My vehicle has less than 67,000 miles on it. I'm told by another mechanics garage service there was a 2009 manufacturer notice about this problem, but no one at the dealer said anything about it.

After leaving a family member's out of state home early on monday august 25, 2014 morning noticed a noise coming from the front of the vehicle. Approximately 5 miles later a burning smell and smoke started coming from the engine compartment along with loud squealing. Pulled onto shoulder of road and shut off vehicle. I opened the hood and it was obvious something had burned up but didn't easily identify what. Called aaa for a tow to nearest mazda dealer. Was informed later in the day by the dealer that the AC compressor had seized up and ruined the serpentine belt as well. They didn't have the parts to fix it which resulted in having to rent a car for 5 days to return home and back to pick up vehicle on saturday. Later found out there was an extended warranty on the compressor for 5 yrs/60k miles which meant that there was no coverage on my vehicle since it was 7 years old even though it had only 49k miles on it. Total cost with towing, the car rental and repair was $1667. They also "found" the starter was bad and a blown fusible link for which they charged another $648. I think they caused the started and fusible link damage trying to start the vehicle with the seized up AC compressor as I never had any problem with the starter before and didn't attempt to start it after I had pulled over and turned engine off.

When it is cold outside and I am backing out or driving forward and I brake it makes a grinding noise. I have had my brakes changed and that was not the problem. It only does it when it is cold out side after it gets warmed up it stops.

As I was driving my mazda ( with a turbo engine) along the highway it began to decelerate on its own and making a loud knocking/grinding noise. It stopped on the road going up a hill with no turnouts. So it appears that the turbo blew up. It will start, but I cannot go anywhere. I have also had to replace gaskets on my oil filter housing unit, as the stock gaskets were faulty and causing a severe oil leak. Also, my emissions regulation ( egr) valve is bad and therefore will not pass smog. Each of these issues I am seeing more and more complaints about from other owners of the same vehicle. Mazda has made a horribly defective car and refuses to do anything about it except to claim owner negligence. I bought my car with 40k miles on it and it has been falling apart from the start. There is absolutely no excuse and this is not owner negligence, it is mazda negligence and refusal to make anything right on their completely defective vehicles.

In september 2013 my car suddenly stopped accelerating while driving it... Heard a loud, grinding, screeching notice.. And suddenly my "check engine" light came on. Brought my car to mazda.. 4 days later they tell me that my turbocharger blew.. And that I have damage to my engine. Told them I purchased an extended warranty in 2010 when I bought the car.. Warranty co was notified... They sent their own inspector to look at my car.. A week later they tell me that they will not cover the damage due to excessive sludge in my engine. And.... That I must produce every oil change receipt from 2010-2013 to show proof of maintenance. I gave them all the receipts I could get... And decided to do a little research myself on the issue. All I have to say is.. Wow. Apparently, there is a major default in how the turbocharger in the 2007/08 cx7... Numerous of service bulletins on the mazda website describing the exact issue with the turbos and how they are very much aware of it, and.. Thousands of forums, complaints, etc about the same issue. However, mazda is not owning up to this problem.. And blaming the customer for negligence! 3 months later, 2 rejected appeals w/ the warranty company.. I am stuck with a car that needs $7,000 worth of repairs, and a 2year car loan left to pay. I am beside myself.. And mazda could care less.

I was accelerating to merge into expressway traffic when I heard a loud whine/squeal from under the hood and the car lost a significant amount of power. The noise was so unexpected and unrecognizable that the shock I experienced when I heard it caused me to tense up and veer off to the right. Fortunately as I was on a ramp there were no vehicles to the right of me to hit. I was able to get up to highway speed by gradually accelerating on the shoulder before merging and then exited at the next exit. The vehicle is now at a mazda dealership and I've been told it was a turbo charger failure. My research into this issue on this make, model and year, has proven that this is a known issue for mazda and they have extended their standard warranty coverage to owners for additional months and/or miles. There has not been a recall however and I think that considering the number of these incidents that have occurred, one would be warranted.

I was driving on a highway. I heard a high pitched squealing sound then smoke started blowing out of my car. I could not see, and the other drivers behind me lost visability too. In the middle of this blinding smoke, surrounded by huge trucks, I lost aceleration. My instrumentation panel did not have any warning lights on. I was driving blind. I pulled off the highway as quickly as possible, and had my car towed to a dealership. The dealership said my turbo blew out, (which I guess sucked all the oil out of the car) I need a vvt valve and the timing chain is stretched. On a car with 57,000 miles! In checking on line, I found this has been a problem with the cx-7 for 6 years and they are no longer making this model. I see that mazda deals with these problems by stating the owner did not maintain the car properly, when in actuality, there is a serious problem with the turbo system and how the oil cools it. There is also a problem with "sludge buildup". I believe mazda has been successfully avoiding a recall. But these issues are a real safety concern. I am very lucky that there was no accident as a result of this incident. These issues can be dangerous. When everything blew on my car, no one could see the road.
