Huge win for car owners! All TSBs to be made public. The Center for Auto Safety just made the NHTSA (US Government) make public the full text of all TSBs from now on. They are the same organization that has petitioned the NHTSA & filed lawsuits to protect car owners over exploding gas tanks & other major safety issues. Whenever you drive in your car, you are safer thanks in part to a lot of work over the years by this small but very effective consumer advocacy group.

Please take a moment & say thank you by donating $5 or whatever you can to the Center for Auto Safety. 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.

While turning right onto a city street the driver side lower ball joint failed. There was no previous signs that this would happen, eg. Sloppy wheel or uneven wear on tire. This seems to be a problem with the cx series and is a current recall with the CX9.

While traveling approximately 10 mph and turning out of a business and into traffic the right, front lower control arm separated from the ball joint causing my vehicle to come to a complete stop in front of oncoming traffic. This has been a recall for CX9's and I am unsure why the issue has not been addressed in the CX7.

While turning onto a main road existing a parking lot, I began to accelerate, all of a sudden I heard a loud pop and could no longer steer my vehicle. My vehicle slowed to a complete stop in the middle of the road. I carefully exited the vehicle to find the front driver side wheel sideways. I was unable to move my vehicle from the road and had the vehicle towed to a local Mazda dealer. I was informed the ball joint had separated from the lower control arm causing $1,300 worth of damage to repair the axle shaft, lower control arm, tie rod, sway bar and alignment. I was also informed the front passenger lower control arm and ball joint were also loose and it was recommend they be replaced, costing me an additional $500 in repairs. The lower control arm defect I experienced on my Cx-7 is the same defect as the Mazda cx-9 recall (8515G). My vehicle was purchased in Michigan and has been driven on Michigan roads for the past 8 years. I believe that driving on Michigan roadways during the winter months for the past 8 years has lead to roadway salts and water intrusion into the ball joint, causing corrosion, which resulted in looseness of both front ball joints. As a result of the front driver side ball joint and lower control arm separating, my vehicle was damaged and caused a serious safety risk. This type of damage should not happen on a car that is only 8 years old. Had the current cx-9 lower control arm recall applied to the Cx-7, my car would have been repaired prior to breaking down while driving. I believe this defect needs to be addressed as it poses a serious safety risk to all other Cx-7 vehicles on the roadway. It is my recommendation to extend the current cx-9 recall to all Cx-7 vehicles.

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.

Excessive tire wear on Cx-7.

problem #1

CX-7 4-cyl

  • Automatic transmission
  • 883 miles
Mazda CX7 (fwd) exhibits abnormal tire wear(cupping, feathering) on all (4) tires after less than 1000 miles. Brought the car into the purchasing dealer who re-balanced and realigned. Tires continued to exhibit the same wear after 2000 miles and ride at highway speeds had some vibration and rough feel at lower speeds. Dealer once again realigned vehicle and increased the psi on all 4 tires to 36psi. At just over 5000 miles vehicle was brought into dealer again, still continuing to show abnormal wear and poor ride at highway speeds (vibration & rough). Dealer realigned and re-balanced all wheels and once again increased tire inflation to 36psi. I later contacted the service mgr and told him that I did not like the fact that he increased the tire pressure over the manufacturers recommended settings and that this would cause the tire to wear down the center quickly.
