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.

  • 18,000 miles


Approximately three weeks ago, I noticed increasing difficulty maneuvering my car and two weeks ago, as I turned onto my street, (traveling at approximately 5 mph), my car actually slid across the intersection and into the curb on the opposite side of the street. Fortunately, no pedestrians were nearby and neither my car nor I sustained any injury. Curious as to why this would have occurred, my husband investigated and much to our dismay, we discovered that my Bridgestone turanza tires ¿ with just 18,800 miles on them ¿ were bald except for the grooves that run along the circumference of the tire. At this time, we called two area Bridgestone dealers who jointly consented that the tire had no tread wear warranty which further served to reinforce the fact that Bridgestone is aware that the turanza is a poor quality tire not worthy of warranty. When questioned about the poor state of the tires after just 18,800 miles, they indicated, that other than the fact that the turanza was a ¿cheap¿ tire (their specific verbiage), it could also be due to poor driver habits or an out-of-alignment vehicle or both. Because I am the sole driver of my vehicle and commute just 21 miles round-trip to my job via a state-maintained road with a maximum speed limit of 50 mph, poor driver habits is eliminated. Furthermore, investigation also revealed that the car was, in fact, not out-of-alignment, as we have now replaced all four tires on the vehicle and confirmed that the alignment was fine. Frankly, we find it nothing short of despicable that Bridgestone continues to sell these tires when fully aware of its poor quality and it is particularly dishonorable that you are willing to risk peoples¿ lives because they are unknowingly driving on inferior, non-warranted tires.

The contact owns a 2007 Mazda CX7. The edge of the driver-side door is curved and sharp; therefore when attempting to enter the vehicle he sustained a laceration. Also the visor on top of the sun roof fractured. The tires tread began wearing abnormally starting at 26,000 miles. The dealer nor the manufacturer have been notified of the failure. The failure mileage 26,000.

I have a Mazda 2007 cx 7 with Bridgestone tires. I have 25,480 miles and do not carry anything heavy. The car is usually used for local travel wih 1 person in it and no more than 2, both of us together weigh less than 300 lbs. Two of my tires have to be replaced and another one within the next 1000 miles. People who have purchased this model have been complaining about tires wearing out at 22,000 miles and Mazda nor Bridgestone will do anything about it. This is a potential problem in which tires will blow out causing either property damage or loss of life. I have not replaced the tires yet, so they are available for insepction. People purchasing these automobiles should have been told that these tires wear out at around 22K miles, since I would have either asked to have the tires replaced or I would not have purchased the car. When you purchase tires from a auto shop, they indicate the normal wear of the tire. All new autos should have the same requirement. I think that Bridgestone used inferior rubber to make these tires since the weight of the auto may have an effect on the wear of the tires.

I purchased a 2007 Mazda Cx-7 from diamond Mazda in baton rouge, la. I have always been under the assumption that a set of tires on a new vehicle would last me at least till I paid off the loan which would be 5 years. I have purchased other vehicles and never had this probably before now. This is the first time that I have bought a Mazda and probably my last. I am very disappointed about the run around that I am getting from Bridgestone/Firestone tire retailers. I was told that this Mazda Cx-7 is a heavy vehicle and that the tires are only warranty for 16,000 miles I have never heard anything like that before in my life. If I have to buy tires every year I will go broke. My Mazda Cx-7 has 16,000 miles on it and the tires are worn to where they are slick. They are very dangerous and for me to buy some new tires will cost me $750. I had no idea that this would have happen to me after only having the car for one year. I see there are other complaints on the same issue. There should be a recall on these tires.

My husband and I purchased 2 Mazda Cx-7's in Oct 07. In Sept 2008 1 vehicle after just 13,000 miles on it had excessive and abnormal wear on all 4 of the tires. We have been advised not to drive much on these tires in the condition they are in by 4 separate opinions we received from the dealership, tire manufacturer and 2 additional tire retailers. We have had 1 flat tire during the process of getting these tires replaced however neither the dealership, car manufacturer nor the tire manufacturer would stand behind the faulty equipment. All agreed that the tires should not wear that excessively however each blaming the other for the problem. Several posts on the internet state the same problem with this tire and this vehicle! I feel I have the right to have safe equipment on my vehicle and I am looking for support to keep my passengers as well as other's who may be driving this car with these tires safe. I would like to mention that the other vehicle of the same make and model bought on the same day has a different tire on the car and that car has normal wear and tear.. to me this is evidence that something is not right with this car and this tire.

Made appt. With Mazda service, regarding excessive tire wear on Cx-7 SUV. I have a Firestone tire protection for this SUV, according to Firestone it does not cover wear. At my last oil change by Firestone, they told me my tires need to be replaced, gave me a price, etc. I told them I would contact dealer and see what they have to say. Appt. Was 8/1/08, I was told my tires are only half worn@20,113 miles. Tread wear was measured @ 5/32 on front and 4/32 on rear. Firestone rotated and ball. Tires @ 5,000 mi. Oil changes. I was told to come back when 50% more wear. Told service adviser this was a safety issue as there is no tread to wear, and mentioned what Firestone had told me. His comment was they just wanted to sell you tires ". took my Cx-7 to ntb tire service, they checked my tires, rear @ 2/32" and front @4/32", they suggested I not drive with these worn-out tires, they need to be replaced. Purchased a set of take-off's for $160 and had ntb align and ball tires. I sent a E-mail to Mazda cust. Service and explained, dealer measured 4/32" not 2/32".I wanted to meet with Mazda rep at any ne Ohio dealer, and have him check tires, etc. They never returned my E-mail. Followed-up with phone call to Mazda cust. Service, they will check dealer, etc. Mazda called back and suggest I take up problem with dealer, they would not set up meeting with rep, etc. If Mazda service dept at dealer can't measure tire tread, and be concerned with cust safety, I would never buy another Mazda vehicle.

Severe steering wheel vibration. Took Mazda CX7 2007 with 12,800 miles to ntbs. They stated severe tire cupping (uneven wear on inside of all tires). Tires Eagle rs-a P235/55R 18 99V. Told me to take the car to the dealer. Did so, the next day ntbs called me with another customer with same problem. Spoke to him, had exact same problems. Both of us concerned with safety and premature tire wear. Mazda only agreed to 50% of cost on his situation due to the fact that he had 20,000 miles. Mazda got back to me and stated that Mazda rep was willing to buy one front tire and I buy the other one. What about the back tires" in any event that"S another issue.. was told that the tires placed on the Mazda CX7, ( 4000 lbs vehicle ) were not designed to hold the weight of the vehicle. This could be serious problems down the road. No pun intended.

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.
