  • Just wondering are you going ahead whith the class action or is Mazda settling these issues? I have a cx7 Motor ready to seize at 70'000km in Aust
  • Hi, I have a 2007 Mazda CX-7. The turbo has gone up with less than 40, 000 miles on the car. We are upside down in the financing and have contacted a lawyer. I know that this is an uphill climb based on postings on forums. Mazda was aware of this turbo problem but has never had a recall. I am interested in how to initiate a class action suit.
  • I am in Maryland. Have just been told that we need $7000 to repair turbo. Have less than 40,000 miles on the car. Have already contacted a lawyer here. We are upside down in our financing and feel totally screwed. am asking our attorney about next steps to
    class action suit.
  • Forget a class action action suit.....go directly to Mazda and insist on your money back, or go to small claims court in CA. You should have a limited recall letter that shows they are accepting some liability, and your car falls under their 70,000 mile rule. Good luck...still working on mine, but I won't give up!!!!!! :shades:

    In the mean time it might be a good idea to locate a mechanic/technician that will "wire" the wastegate fully open. You won't have "boost" power levels by the car should be driveable.
  • On October 23 I got off a plane from Philadelphia, PA to Jacksonville , FL and required emergency surgery.

    Sounds like what my CX7 Turbo may require. I am slowly recovering, CX7 with only 6,500 Miles
    Is ailing very much.

    I am leaning toward cutting my loses and dumping CX7. Mazda just doesn't seem responsive and I need no further agrevation.

    I bought the 07 CX7 new and just loved it at the beginning, but then problems after problems. The VVT/timing chain went out the mechanic told me to get rid of it I might get another year of driving. My cx7 was paid for and didn't want car payments so I kept it. What a mistake!!

    I was stranded 6 hrs from home for 6 days when the turbo went out. I traded it in 2 weeks after the repair and loss of money. I'm happy to say I'm now driving a Chevy Malibu, it doesn't have all the bells and whistles the madza had but 4 months of smooth driving!

    I wrote Madza a letter both times after the major issues and they don't care!! :lemon:
  • I dumped my CX7, to cut my losses and grief.

    Mine had 64,000 miles, just 4k miles after warranty expired, and at the time I still owed $11k :( . Timing chain snapped and ruined the engine; dealer offered to replace engine for a little fee of $8,500., really? and replacement engine would come with 1 year warranty. So, because of this flawed design, I would probably have to buy a new engine every year or two, WTF?

    I got rid of mine; sold it with broken engine to a place that buys broken cars to auction, for $6,500. I still owed $11, so I had to pay out of pocket/up front $4,500. This was horrible; but I did it because I felt that I would not trust that car anymore, even with a new/replacement engine.

    After dumping the CX7, I went and financed a new Toyota Prius, and that has been one of the best decisions I've ever made.
    I used to spend $65-$70 in gasoline per week on the CX7, and now I spend $27 every 2 weeks. I save over $200 in gas, and have a truly reliable car.

    Thanks Mazda; never again!

    I have had all the problems listed in this long thread. Turbo failed, AC condenser replaced, timing chain, and now the motor. 2007 CX-7 with 54k miles. Turbo problem came around 35,950K. At the time, the 70k extension had not come to fruition yet, so I was operating under the 36k warranty. The problem actually happened under warranty, so I purposely left it in the garage and called dealer. Told them that I was coming in and by driving it in was going to be just over warranty mileage. They suggested that, just in case, I should TOW it in to stay under the mileage. I told them BS, drove it in anyway, and told them to fix it. Several months later we got the letter regarding the 70k extension.

    FF to two weeks ago. Took it in for an early 60k service. Basically $800 for a fancy oil change, not even tune up or plug replacement. Got it home, and two days later it starts with a heavy tick. Not the small ticky valve noise that comes standard with the vehicle, but a louder clack. Took it back in, told them that it was either a) VVT or b) timing chain. Turned out to be loose chain, and they replaced it. Said VVT was fine, no sludge, etc. Gave me grief because the car is 5 years and 4 months at 54k, and that technically it would be considered out of warranty, but again, I called BS. I simply don't take no for an answer, clear and simple. So, it was settled. I go to pick up the car, the tech drives it up to me and gets out and says "what did you have done to this?" I tell him the chain, and he says, "oh, that's weird because it doesnt' sound right." So I get in, and......clack is still there. Manager comes out, hears it, goes back into the shop for about 5 to talk with mechanic, comes back out to tell me they want to take another look at it. Well, to shorten this, they find that #3 valve has lost compression and motor is toast. Tomorrow I find out if they will pay for a new motor.

    Just with everyone else, they asked for all oil change records, etc. We had all but 3 performed at dealer, and gave them receipts. A note on this to any Californians - it is State Law that you can get your oil changed at other places other than the dealer without risking having your warranty voided. So don't let them tell you that. Anyway, I am under 60k, but over in years by a few months, expecting a fight on this. These other problems no doubt had an effect on the motor. I must say, my particular dealer has been pretty good to work with so far, despite all the problems. Corporate Mazda is another story. The Mazda mechanic working on my car now is supposedly one of the top in the nation, and even he told me that these 4-cyl turbo motors are awful and nothing but problems. I'm prepared to go all they way if corporate tries to stick me with the cost of a new motor.

    One more note to everyone - unless you truly were negligent with your oil changes (waiting until 7500k - 10k), the sludge build up schtick that Mazda falls back on is actually caused by the excess heat and oil build up that gets trapped in the Turbo. That turbo supposedly generates a ridiculous amount of heat, and the oil that gets pushed through does not get fully expended. So, it you get your oil changed every 5k, even 7500k, that is not the cause of the sludge.
  • I need to know if this works? I have 2007 CX7 and I have a blown turbo but runs still I have had a wheel come off abnormal brake wear and its just a disaster I will NOT put 2k into this junk and owe way too much to trade since only have had for 10 mos please give me some way around this to drive a few more months and take a bath but get out from under this junk
  • My '07 Mazda CX-7 has been acting up for about a year now. We finally decided to take it to get worked on. The first guy we took it to kept it for about a week and said the Timing Chain need to be changed. However he never fixed it. Then we took it to another guy who could not fix it, because he did not have all the tools. So we broke down and called Skyland Automotive in Asheville, NC. Upon first quote, it was going to cost a little over $700. When my husband called back to say we would bring it in, they said it would be an additional $200 to replace the water pump.(This was Friday) We dropped it off last night, because the parts came in. Today we received a call that the Variable valve timing actuator button was missing or had fallen out. This was going to cost another $180 dollars to replace. They thought it may had fallen into the oil pan and wanted permission to check. Just received another call saying that they found half of it and wanted to take the oil pan off(thought they were going to do that already), but if they did, it would cost another $129 dollars.. Finally told them to fix what they could and that we were not giving them another dime.

    I should have known not to take it to them. they tried this crap before with my Mazda 6. My fan in my engine stopped working. Took it to them to figure out what was wrong. They said it would cost $600 to replace the whole housing unit...... I laughed at them! I found out which fan was not working, found a replacement on E-bay for less than $4 and free shipping. Changed it myself. So that repair that they wanted to charge $600 for, cost me $4 and about an hour of my time.

    Dealerships are the biggest rip off.
  • Mazda has a recall on this item that covers up to 70K miles. You should not pay out of pocket if you are within this mileage. Also there is a lawsuit in the works.
  • Well, Mazda got back to me today. They have offered to replace the engine with a rebuilt, but said I would have to pay $2800 for the labor. I got Corporate's number, called them and had it seriously out with them over the phone. They were sticking to the time side of the warranty as their excuse not to pay all. My vehicle is 5 years, 4 months, 54k miles. I told them thanks, but I won't be paying a dime. Waiting to hear back again. If any of you deal with corporate, be strong with them. They'll just say its Mazda policy, and that they don't make the decisions. There is SOMEBODY making these decisions, you just need ti find a way to get to them. I would like to be in on any lawsuit if this doesn't work out. All these inconsistencies with they way customers get treated for the same problems is what really pisses me off.
  • I have had my 2008 Mazda CX-7 for just about a year. I bought it used from Carmax and purchased the extended warrantee. I'm curious to know what symptoms you are experiencing. I have noticed some "slipping" or RPM deceleration when driving at lower speeds. I am going to take it in to Carmax to have them take a look. I read earlier posts of people who thought they had a transmission issue but it turned out to be a sensor and was relatively inexpensive to fix and solved the problem. I don't know a lot about cars so I'm concerned that I don't know what else the symptoms could indicate - ie, timing belt, engine, transmission etc. Lastly it seems that a lot of problems occurred with the 2007 model. Are the 2008 CX-7's not having the same issues? I am in Maryland as well so I'm curious as to your results. Thanks! Also my car has about 43,000 miles.

  • TRADE THIS IN BEFORE ITS TOO LATE- DO NOT TAKE THIS LIGHTLY-PROBLEMS ARE LESS THAN 6K AWAY- DUMP THIS ASAP!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!- !!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!! :lemon:
  • Thanks for the quick reply. My issue I think, is with the surge or deceleration I experience at a certain speed. It doesn't happen all of the time and typically not when I'm going fast. I cannot afford to put $ into a problem car. Has a lawsuit been filed? Also are problems being found with 2008 models or mainly with 2007 ( the first year model was made)? I appreciate the help and advice.
  • 2007 was the most troubled year but 2008 was no better and problems continued even later. While I can't help with surge/deceleration concerns, I may be able to help you with respect to the VVT /timing chain issues. You can reach me through my profile information, or just pose a question here on the forum.
  • I sympathize with all the owners. Are most of you in the USA? I am in Canada and I have a 2007 CX7 with 125,000 km (77,680 miles). I just recently started to hear the slapping noise associated with the VVT/timing chain. I took it to the Mazda dealer and no problems. Yeah your VVT and timing chain need to be replaced and it is still under warranty. I just did an oil change in October so they are including one with the repair. I'll pay extra for synthetic oil as that is what I run. I don't know why Mazda in the USA is so deceiving...maybe because of a larger amount of owners? My CX7 has been paid for a couple years now so I don't think I'll switch vehicles. I have new snow tires and rims and brakes all around, so I'm hard pressed to trade it in for something newer and different. I guess I'm fortunate to have a good honest dealer. I usually check the BBB and CAA (AAA) for dealer recommendations before I go to one. I travel about 20 km to the one I use because the one closest to me has a very bad reputation.
