Mazda CX-7 AC problems



  • I purchased a 2011 CX-7 Grand Touring AWD and the first thing I was advised to do by my mechanic was use synthetic motor oil. At this time I only have 500 miles, but the CX-7 runs very nicely, quiet and no problems.

    Should you not get the results you expect from Mazda there is the lemon law and a class action law suit. I am learning that if you do not stand up for your rights no one else will.

    Post your problem on every site you can thing of and that way get the satisfaction of knowing Mazda is getting the notice they deserve.

    what did mazda say?? i have the same problem? on a 2010 with only 11k miles
    the noise at start up
  • I own a mazda cx-7 2009. At 42000 the air conditoning compressor went bad. I called and took car to dealer and had a similiar situation. It cost $1,100. this wasnt covered under warranty as the car had 6000 mile beyond the 36000 maximum allowed. Total EXTORTION. If the compressor is going bad after 2 years there is obviously something very wrong with the quality of it.

    Customer service checked the vin number on my vehicle and stated that it did not have a service bulletin on it. However, other same car different year do. I find it all very odd. Again there ought to be a consumer protection law.
    Apparently, they are taking advantage knowing that if you own the car live in florida or in any other warm city you have no choice but to repair but to pay to repair a defection a/c part. Totally rediculous.
    Overall, very unsatisfied with the experience of this car. During the first months of purchase the enterior quickly began deteriorating, one front head light went bad, had to replace battery and very expensive on gas. Looking forward to getting rid of it.
    The price may be lower than other SUV's such as murano and lexus, highlanders, but at the end you end up paying more and getting less. The quality is not there and either is the service.

    I have a 2008 CX-7 and I never got such a letter. If one of you guys could scan and email it to me, that would be great, because I've got the AC compressor problem, too, at 47,000 miles, which seems about right. The problem is that I may have a very hard time getting reimbursed. I would like all the information I can get before I go to Mazda with this. Perhaps I can convince them to help me if I can prove that I should have gotten the letter, but that they never sent it before I took the car out of the country.

    I'm a Foreign Service Officer at the US Embassy in Bogota, Colombia. I keep you safe by keeping the cartels and terrorist OUT of the US. The government sent me and my CX-7 (bought in Pennsylvania) here in November of last year. While driving through the country on a Sunday evening with my daughter about 50 miles north of the city, the unit seized, the belt incinerated itself, etc. We were stuck, and you don't want to be stuck in rural Colombia at night, especially if you are a gringo with diplomatic plates. We got a tow (complete luck) back to Bogota for Col$300,000 (about $165 - not bad for 50 miles on a Sunday). It was fun sitting up in the car on top of the tow truck, and probably very illegal in the US. Problem #1 is that the car is not warrantied out of the US and Canada. I ordered the compressor from Mazda USA through the APO, but the repairs still cost the equivalent of US$1,200 because the miscellaneous parts cost a bundle here. perhaps I can convince them to pay me for the parts, at the US price. I'll mail them to them.

    Problem #2 is that the car doesn't run as well as it did before. The thing is a pig until the turbo kicks in at about 2800 rpm. It has no power. In addition, at low rpm's, I lose the power brakes. I did not have that problem until immediately after the AC seizure. Anybody have any idea how it could be related? Suggestions appreciated, because I am dealing with Mazda Colombia in Spanish - not my native language. In addition, these dudes don't have the same cars here. Their CX-7's don't have all our US emissions controls, etc. They may not have the sophistication that our US Mazda people have (or think they have). By the way, Bogota is at 8,500 feet above sea level. Temperatures are usually between 55-70 degrees. I drove up a mountain pass today to 11,000 feet and the temperature gauge went very hot for the first time ever. What's going on here?

  • I had the same exact issue with my 08 Mazda CX-7, car started smoking, popped the hood and noticed that the ac compressor was stuck, continued driving and the belt burned up! I have a warranty that covers powertrain only but will definitely call Mazda tomorrow and ask about the recall - do I have to have the letter? If not can somebody please, please email it to me? I bought the car because I just had a baby and thought it would be safe for us but it actually left us stranded on a lonely highway at dusk, we had to wait 1 hour for a was horrible to say the least.
  • I am having the same problem with my AC Compressor and do not recall having received a recall letter. Would it be possible for you to e mail a copy of the one sent to you?

    The guys that want a copy of the letter have either to change their email setting as stated by steve (host) OR, as stevie1026 did, put it in the body of the reply. He will receive his today but the rest need to realize I can't email you if you don't give me the address!

    This isn't working - all people are doing is posting contact info in the forum, which is spidered by Google and Bing and the rest of the search engine. That means that every one of y'all is going to wind up on spam lists.

    Plus it's against our forum rules, so we're going to clean out posts with email addresses in them.

    You could just change your email to public in your profile.

    Even better, take a picture of the letter, block out any identifying information, and park it on a photo hosting site like and simply link to it. Then people will be able to find it in two years without having to try to track you down.
  • Can you send me a copy of the letter as well regarding the AC issues? We are having a bear of a time with this.

  • pctechpctech Posts: 43
    I would be happy to do this but your email address is set to "private" so I have no place to send it. In the future, anyone who wants a copy of this letter MUST have a visible email address in your user profile. I don't have time to keep asking, so I'll just ignore the request in the future if your address is not visible the FIRST time I check!

    Can't you just park this stuff on Flickr or Photobucket and link to it? People are going to be asking about it for years to come.
  • Please shoot me a copy of this. 2007 A/C smoked out last week at 48K.
  • I found the letter! PM me and I'll email a copy. Tom
  • The AC compressor is not a recall, the warranty on the part was extended to 60,000 miles - if your AC compressor breaks after that, you're responsible for the cost of the new compressor. I bought my Mazda at 60,000 miles and the AC compressor went out at 68,000 miles, I got sooooo lucky because my Mazda dealer replaced the part and only charged me $100!!! I love Mazda!!!
  • Can I please get a copy of the recall letter for the 2007 - 2008 CX7 AC problems? We have a 2008 that we purchased in Sept 2010, it has less then 36,000 miles on it (still under warranty) and it has started Smoking. We do not know if it is an extended idle problem because my hubby let it idle while he was doing some pdr on it, and so oil might have got in the turbo or if it is an AC problem like others have had when theirs started smoking. I have this account linked through my profile on facebook, it could send it there or use the email provided in facebook, I would really appreciate it.

    I am having the same problem with my AC Compressor and do not recall having received a recall letter. Would it be possible for you to e mail a copy of the one sent to you?
  • pctechpctech Posts: 43
    I don't mind individually sending copies of the letter, though I expect that, if you qualified under the program, you would have received the letter. Since I'm not going to post it to one of the "sharing" sites, you must realize that it's impossible for me to email you when your address is not available!
  • What kind of documentation did you receive to advise you that the warranty on the part was extended to 60,000 miles? mine just blew at 55 and I am seeking retribution. The repair guy even gave me the old one to take to Mazda to show them.
  • Hi, I called the Mazda corporate office and they told me about the extended warranty - they also told my Mazda mechanic. Like I stated before, its not a recall (even though I think it should be), its an extended warranty. Has your car been fixed yet? If not, its best to take it to a Mazda repair shop because they deal directly with Mazda corporate and corporate with pay the bill directly otherwise if you go through somebody else besides Mazda, I believe Mazda will reimburse you but it might take some time and I'm not sure you want to wait - its about $1000 to fix. Good luck!
  • I picked up my car today, I had it fixed by Aamco, who was wonderful. The starter went also (again, only 55K miles on my car)!! So, both combined it cost me $800 with labor and tax. The compressor came directly from Mazda because they don't make an after market one for the CX-7, or so I was told....still, paid alot less than the dealer would have charged me. The man at Aamco told me to be persistent with Mazda, he has seen situations like this with other cars, Ford precisely....he said Ford makes the compressor for Mazdas.... he gave me my seized up compressor in case I needed to bring it to Mazda. Such a shame, I haven't had a single problem with the vehicle until now and I have always loved it. We have been looking at trading it in recently and I believe we will pursue that avenue.

    I will check on the extended warranty, thanks!

    Mazda is taking the steps necessary to right its financial ship, but when a patient has this kind of issue, the cure can hurt just as much. The small, independent carmaker has been hurt by its relatively Japan-centric manufacturing base and the strength of the yen, the loss of Ford as a noteworthy stakeholder and the resulting loss of financial cushion. Mazda is expected to post a $1.2 billion loss for its 2011 financial year, which is smaller than earlier estimates but it's still the fourth losing year in a row and the largest in a decade.

    The need to act has forced Mazda North America into a five-month plan to shed a number of its 701 employees for leaner running. Select employees will be offered a buyout package, and if voluntary uptake isn't sufficient then involuntary dismissals will occur. The timeline begins this month with lump-sum offers, followed by layoffs at the end of May if necessary, and the stretch to August will see the transition of personnel into the restructured organization.

    Mazda is also issuing shares to raise $1.9 billion in order to aid its position and get production started in Mexico and Thailand. It is also aggressively seeking a partner and considering licensing its SkyActiv technology.

    2007 CX 7 Sport 2WD. Bought the car 2 years ago with 38k and have had no problems until this year. The end of last year, the car would occasionally go into a limp mode limiting the car electronically. I couldn't go over 30mph. Took it to the dealership and they replaced the throttle body for $1k.

    Then, the wife and I decided to go to the Grand Canyon last weekend. On our way back to Vegas, we were outside of Kingman and the a/c out of no where started blowing hot air. We started testing it going down the highway for a couple minutes and decided to turn it off after we saw smoke and roll down the windows. We set the cruise for 75 and just tried to stay cool. From kingman to vegas is about 100 miles so we made that fine. The car did make a bad sound. I don't know how the belt held up but it did. When I pulled into my driveway, the car stalled. I started it back up after we unloaded everything and took it to the firestone just downt the street. They quoted me $2100 to fix the a/c. Then I started researching online and I was outraged at what I saw. I am at 68k miles (8k miles out of warrranty). I could have been stranded on the side of the highway in 90+ temps... I went back and forth all this past week with Mazda and they would do nothing unless I took the car to the dealership and paid the $107 to have them agree with me that it is the a/c problem even after I have the paper from Firestone saying it is that i paid $50 for. Mazda wouldn't budge at all!! I decided to pick my car up form Firestone before they accidentally fixed it and I would have to pay over 2 grand... I drove my car home and the engine stalled again. I was able to get it going again after feathering the gas pedal a little. I started making room in my garage to prepare working on the car and the thing stalled again. After 30 minutes it went from the motor turning over reallly slow to the starter just clicking because the serpantine belt won't budge. Now it's stuck in the driveway. I just ordered a new compressor, dryer, and accumulator online for about $400. I'm buying a new serpantine belt and o ring kit from autozone tomorrow for about $50.

    Tonight, I'm going to cut my current serpantine belt so I can start up the car, turn it around and back it into the garage real quick. Quick is the key here cause the water pump is run off the belt and I don't want to overheat the motor. driveway is a slight hill and can't push it up it. Should only take me a couple days to replace the parts. Once I get everything put back together, I'm going to have to leave the a/c button in the car off so i don't burn the new compressor up and drive to an a/c place to charge my system for around $100. after that, I should be good. total spent shouldn't be more than $550-600. Much better than $2100+....... Me and the wife don't plan on keeping the mazda much longer. The car is great, but the attitudes I recieved from the company was some of the worst customer service I have ever recieved.

    If you take anything from this, If they don't fix this with a recall in the future, you can do this yourself and save a lot of money. I do have a motorcycle that is currently my daily driver until the mazda is fixed so most people don't have that option but it is something to think about if you do. Also, I had a hard time finding a service manual for our car. I did buy a 30 day subscription to Chilton DIY online for like $15. it has some nice picutes to help with the install. Wish me luck!!!

    Good luck with the fix. Some of the links in the Online Repair Manuals discussion may help.
  • wwestwwest Posts: 10,706
    Neither Firestone nor Goodyear should ever be trusted by anyone insofar as price estimates. They see problems where non exists and beware of up-sells/add-ons.

    You will need to have a shop flush the system of metallic "fines" before you install any new parts, most especially a compressor..

    Strange failure mode, the compressor clutch not releasing, have you tried removing the clutch voltage source?

    The reason you heard the clicking is because the battery is dead, the alternator hasn't been turning....

    We have a 2011 CX7 Grand Touring AWD Turbo with under 5,000 miles. AC was not cooling properly took to dealer and told operating correctly. After much frustration took to AC specialist and unit was under charged by half volume. Had completely charged at cost of $80.00. Car gets ice cold. Mazda not receptive to any information provided and basically states what I did was on my own.

    Can anyone advise what I may be in for with the CX7 AC system. AC specialist advised that system is problem prawn.
  • tselftself Posts: 1
    I have a 2011 CX9 and I've had nothing but problems with AC. Mazda keeps saying it's normal but when the AC starts blowing hot air when I'm sitting in traffic doesn't seem normal to me. I took it in to a dealership for the 4th time last week because they said they had a fix for it. The fix doesn't work. I'm completly lost as to what to do next. I live in Texas with 110 degrees as the average temp during the summer and my car won't keep cool unless I'm going 60 without stopping. I will NEVER own another Mazda again that's for sure!!! :mad:
  • wwestwwest Posts: 10,706
    Your engine is "tending" toward overheating. Most newer cars, if the engine coolant temperature begins to rise rapidly(??), or rises to a predetermined point below actual overheat, will disable the A/C automatically. Has your dealer checked that the radiator cooling fan(s) are operating properly, going into full high speed early enough to prevent a rise in coolant temperature in heavy stop and go traffic?

    Check to determine if AC blows hot air after vehicle first started from cool overnight parked state with re-circulate off. Check to see if AC blows hot air only after vehicle has been driven a while then parked a short time again re-circulate off. Turn on the re-circulate switch on the AC to bypass the incoming air to prevent hot underhood air from getting into the system and check again. Turn the blower on high while driving and see if the AC eventually does work about ten minutes. Any difference then the problem may be hot underhood engine air overpowers the AC system. Design of system the intake AC air is not coming from outside the car instead from the engine compartment. More you drive the hotter the engine compartment gets and the longer it takes the AC to compensate. If the AC works properly on a cooled overnight system the problem is most likely hot intake air overpowers system. Fix for this problem is to change the AC control module to allow you to set the re-circulate even with the AC compressor is turned off. Not the ideal modification but at least a way to keep the hot air out of the car until the underhood air cools down which takes a bit of driving at decent speed.

    Many owners of the new water cooled Porsche 911's in that climate modify the radiator cooling fan circuits such that they can "pre-emptively" run the radiator cooling fans (2) at full speed using a simple on/off switch.

    You can also lower the HEAT load on the engine cooling radiator flowing from the A/C condensor. Bypass the A/C system's reheat/remix mode.

    Run the system in recirculate and the max cooling position then use the blower speed to moderate the cabin cooling level. The A/C compressor duty-cycle will be lower then otherwise, less HEAT from the condensor.

    There is an easy way to check the AC system to determine if the hot air problem is a faulty compressor issue or an overloaded system.

    1. Open the glove box remove contents and press side tabs to drop it down.
    2. Remove filter cover plate from air intake and remove cabin filter (flexible sides) comes out easily.
    3. Turn the AC off and fan on high with re-circulate off set temperature low.
    4. Put a thermometer or even your hand into filter slot to check intake air temperature.
    5. Compare intake air temperature and to ambient outside air temperature.

    Both temperatures should be about the same no noticeable difference whether the engine and underhood compartment is hot or cold. A big temperature difference after the engine has been run hot then left off for a while as compared to when the engine is overnight cool means the intake air is very hot so overpowers the air conditioning system.

    To overcome this problem set the re-circulate on and use the AC to cool cabin air instead of intake air.

    There is no ready fix for this problem as the air intake pipe opens to the underhood channel on top of the engine at front fo the windshield. So it gets really hot if the vehicle is idles excessively when not enough air gets into the engine compartment to cool it down.
  • wwestwwest Posts: 10,706
    I don't know of any reasonably modern design that doesn't have a GOOD rubber seal between the hood and the firewall in order to keep engine compartment air/atmsophere/heat from entering the A/C outside inlet airflow duct.
  • e_bustere_buster Posts: 5
    Regards to the firewall to hood seal, it does not block air from the engine compartment. Plus the location of the intake duct, windshield air chamber and ambient air intake grills causes mostly hot air at low driving speeds.

    Notice the firewall top rubber strip extends the width of the windshield except it does not seal the corners of the engine compartment. Look again you will see the intake grills on bottom of the windshield outside are on left and right sides of windshield immediately behind the openings to the engine compartment. Note also the air intake connects to a metal bottomed chamber below the front of the windshield also houses the wiper blade assembly.

    Have dismantled the whole lot and determined the hot air from the engine compartment gets rammed into the chamber through the upper corners where the firewall seal does not extend. Plus the metal on the chamber bottom gets extremely hot due to the engine and exhaust pipes being so close underneith.

    So the air conditioner intake draws the air from the chamber which can be very hot if the engine has been run long and then stopped. Takes a really long time for the small amount of outside ambient air coming into the windshield drip chamber through the upper grill runs along the bottom of the windshield to not be heated if the chamber was hot.

    Grill design is similar on Mazda 3, CX-7 and CX-9 vehicles none of them have a completely sealed firewall. Although the CX-7 GT is and Mazda Speed 3 are the most affected due to the very hot turbo and intercooler located just a couple inches below the windshield air intake chamber.
  • wwestwwest Posts: 10,706
    I don't own a Mazda but a quick check of mine and my neighbors' stable(***) indicates that the more common placement of the seal in question is forward of the cabin's fresh air inflow path.

    On Mon. July 9th took my 2011 CX7 Grand Touring with 5,000 miles to dealer for AC repair. AC was doing nothing not lighting up certainly not cooling. Told fuse had blown to AC and a wire needed to be reconnected. Dealer performed work. AC back on. If CX7 bakes in driveway for a few hours when temps are 90-100F and you first start CX7 AC makes banging noise. AC never seems to get COLD eventually cooler, but not cold after 1/2 hour or longer. At best 68-65F is what comes out of center vent. Our CX7 is black and perhaps this causes it to get hotter than a lighter car, but CX7 stays really hot. Neighbor suggested having side windows tinted; do not know whether this would help. Returning to dealer July 25th. Does any one have any suggestions, am very frustrated.

    On Sat July 14th driving my 2011 CX7 Grand Touring with my family when AC went dead again. The outside temp was in the 90's. Purely by accident I was by a automobile restoration business and employees came over to CX7 to see if they could help because I had pulled over. I said AC went dead and they offered to take a look. Came to conclusion that my system had air in it. Told that system had been low and refrigerant had been added. Fuse had blow before and dealer replaced a nd re attached lose wire. Restoration owner spent over an hour evacuating my system and refilling with refrigerant. Replaced fuse and "set up my system". While talking with mechanics told of taking into two sepereate Mazda service centers and had AC gone over by these centers. Automobile restoration business would not take money from me. Told they believe they found and corrected problem. Just blown away that owner refused to take any money from me. Owner said that working on my AC was a learning experience for them, glad they could help me. Will send thank you and gift card. G-d bless good mechanics who care. AC has been working well; I think they fixed my CX7 AC correctly. Why couldn't Mazda find the problem? I was in and out of both Mazda service centers in no time, told I was good to go problem was repaired. May good mechanics live very long lives, we certainly need them.
  • md1988md1988 Posts: 1
  • I didn't have all the problems you describe but I live in AZ and thought that the AC was simply not strong enough. I mentioned it to my dealer.

    Although I have not found the TSB online yet, my dealer said that one has just been issued for this vehicle regarding this issue (weak AC) . I suggest that you check with your dealer. Mine just ordered the parts per the TSB directive.

    Other than that, I have had no problems with the car. I find it interesting how many people with 2007-2008 CX 7s complain on this forum. Did anyone not ever tell them to not but any car in its first or second model year :confuse:
  • wwestwwest Posts: 10,706
    "..not buy any car in its first or second year..."

    Or in this case not even one in LAST year.

    My girlfriend owns a 2007 CX-7 and the AC unit just went out on her car. She drove it down to the dealership and by the time she got there it was spewing smoke like crazy from under the hood. Dealership called her and told her that it damaged the crank shaft and that all this work needs to be done to the car in order to get it drivable again. She has 68k miles on it which means it's past warrenty. She has had all of her maintenance done by the dealership. She never received any type of recall letter on regarding the AC. Is she completely screwed or is there something we can do? Dealership said it was going to cost about $2,150 to get the car fixed.

    The Secret Warranty
  • We have a 2011 CX7 GT Turbo that only cools when we are going over 2,000 rpm. CX7 only has 6,000 miles and has been in for services at Mazda dealership where I am advised that AC is operating at Mazda standards. When our CX7 has been sitting in ninety degree heat and we get in and start it AC starts by making a banging sound. If we are able to maintain 2,000 rpm for 20 to 30 minutes CX7 will eventually cool down. If we are in city traffic you get no cooling from AC and roast. I am under the weather now and can not take CX7 in for service, but I am disgusted with Mazda not being able to find and remedy the cause of very poor AC. Also getting banging from Turbo when need to accelerate quickly.
  • I have recently put our $1150.00, that I could not afford to replace my ac compressor that nearly caused my engine to catch on fire. Had it not been for the torrential down pour that I was driving in and 2 block distance to my home, I would have been in a very very dangerous situation and lost my vehicle. I deserve and insist on a refund. My mechanic has documented the work and I have saved the compressor to show mazda how it literally "melted. It got so hot that it glowed red.
    I have done a lot of research and am finding that many CX-7 owners have experienced the same problem and never received a recall letter. I am desperate to get my money back. I have a disabled husband in End Stage Renal Failure and cannot afford this. I had to borrow the money and need to pay it back somehow. If anyone has this Phantom recall letter, I beg you to send me a copy. I hope that nobody else has to deal with this either. Other than this problem I have been quite please with my Mazda. Come on folks, do the right thing.
  • I am desperate for a copy of this letter. I have just shelled out 1150.00 for a compressor that seized up. It got so hot that it glowed red. It could have been a serioulsy dangerous situation. I was unable to drive the car and also put money out for a rental until the work was completed. Would you be as kind as to contact me with a copy of this letter. Thanks so much.

    I just had a meltdown at the dealer I bought this vehicle from 10 months ago with the exact same loud noise and AC problems! They told me there was nothing wrong, treated me like I was hearing things or imagining the problem and watched me walk away. I'm grateful for all these postings that I can now share with a new mechanic to prove I'm not the only one. My AC makes a horrible loud noise when clicking off and on and you can hear the timing belt rattle and grind. Who knew?
