    did the dealership determine the cause? we are having an issue with gas mixing with the oil and so far they haven't been able to determine the cause of the problem. We have had new injectors and three different fuel pumps installed and still the gas mixes with the oil and overfills it.

    the dealership in NYC could not determine the cause of the problem, they figure is best to simply rebuilt engine.
    they had the car for 3 days only to have to take the car out, pay for the troubleshooting and I ended up trading the car. HUGE FINANCIAL LOSS, get rid of yours before you are in my shoes. Mazda did nothing about it.
    they know these engines have a lot of problems! but they just dont care about us!

    I have a 2008 CX-7 that I purchased less than a year ago. Two weeks ago at only 65,000 miles I started hearing a knocking sound coming from the engine. I have an extended warranty that I purchased when I bought the car so initiallly took it to my mechanic who then told me to take it to Mazda since the issue should be under Mazda's extended warranty of 70,000 miles. Mazda replaced the VVT actuator and timing chain at no cost but the issue was still there. The Mazda service department said that the engine needs to be replaced and that they won't cover it due to "sludge buildup and lack of maintenance". They had previously stated that my engine was spotless. The extended warranty company won't do the repair placing blame on Mazda. I have a vehicle that I have owned for less than a year with only 65K miles and am stuck either replacing the engine at a cost of $6,000 or trading it in and taking a huge loss. I am interested to see if there are any class action lawsuits being filed and how to get involved if there are.

    Trade it while you can. I went through the same thing, replaced the engine at over 6,000 and that did not work ended up scraping it and needed to buy other car. Over 8,000 in repairs for nothing and Mazda did NADA. Get rid of it earlier than later.

    When my engine was replaced, they obtained one that had the same Vvt problem as the original and it started to exhibit noise and other symptoms 11k miles after replacement! Thankfully it occurred under the 12k / 12 month warranty for the used motor and repairs were covered. However then the CX-LEMON started stalling with CEL indicating the throttle body needed to be replaced (not covered under extended warranty) and the car was subsequently traded in quickly to cut any future losses. DUMP YOUR MAZDA CX-LEMON!
  • Your problem sounds very similar to mine. @ around 30,000k my turbo, fuel injectors, plugs, fuel pump and exhaust sensors went. Thankfully this was all covered under warranty. I had very few problems with it except a seal and the odd random check engine light that would come and go, they(dealership) told me not to worry about. I had a gut feelin to sell the car @80,000k but I liked driving the car and its good in the winter roads here in Edmonton. So at 103,000 (3000k past warranty) I had to pull over on the side of the road in small town northern Alberta due to an odd feeling loss of power(not complete loss). Oil all over the ground and on the back of the vehicle. After a $500 tow to town I come to hear that the connecting rod blew out the side of the engine block. $8,000 they want to fix it. Mazda won't cover anything. Even though I just had the 96,000km inspection/synthetic oil change 5,000 k before. Which of course said everything was good. Very frustrating and it's still at the shop because I'm not even sure I want to fix it. Even if I fix and sell it ill have to deal with the guilt of someone else getting hurt financially because of this CX-Lemon

    I've got a 2007 Mazda CX-7 Touring with 132K miles. All of the recalls have been fixed, and I'm getting a consistent CEL with code P2006. Went to Autozone and these are what the notes say could be wrong: 1) Disconnected or damaged vacuum hose, 2) Binding VTC actuator, or 3) VTC solenoid malfunction. Any tips on what I should try to fix first? Has this happened to others of you out there? Thanks!

    my cx7 AWD-GT went bad with similar problems at 75K miles, mazda laughed in my face stating that my problems were from wear and tear.
    I told them that i never had to replace pistons, VVT actuator, belts and hoses along wth a rebuilt of my turbo in any car I owned before 75K miles.
    on top of the electrcal problems that I had which were never solved!
    I drove a 1991 accord with 150K miles and all i did was tires, brakes, water punp and a new radiator at 141K miles. By the way that car is still on the road with over 225K miles today..
    my cx7 was sold at a loss! MAzda will never get my money EVER EVER again!

    mazda sucks, i sold my car at a loss!
    mazda laughed in my face, turbo went out, cylinders had misfiring troubles, the engine needed a rebuilt at 75k miles.
    mazda knows that this car has a lot of design flaws, starting with the turbo cooling and the actual engine design for this car, that is the reason this car is no longer sold in the usa.
    mazda will never get my money or my respect ever again.
  • I bought a used Mazda CX-7 2007 from a dealership with 93K k.m last September,2012. On April, 24, 2013, I was on my way driving home as I heard a bang noise, car lost power and stopped on its own. I tried turning on, but it wouldn't. I towed it to the local Mazda Dealer, after their diagnostic, they told me that the timing chain is broken, which as damaged other pieces inside too. Now, I have to change the whole engine since the engine is blown. There is a "SPECIAL SERVICE PROGRAM SSP 87) from Mazda Canada but they denied taking responsibility as the owner before me, did not change oil at Mazda Dealer so the "Warranty" was cancelled. Mazda dealer estimates the engine replacement cost at about 5000-5500$. I financed this "family" car for 10000$ and I haven't even used it for a year, only 7 months. Now, I have to take another loan to repair it. Horrific!!! Guys, do not buy Mazda, and do not be fooled by the fake Warranty program of Mazda. They always find excuses to deny you any warranty.
    Not Mazda ZOOM ZOOM but Mazda BOOM BOOM BANG!!!
  • My daughter who is a full time college student purchased a CX-7 used nearly a year ago. She still owes $8,000 on it. It has the same timing chain issue being discussed in this forum (Loud noise followed by dead car). Her car has 112,000 miles on it.
    After incessant phone calls and emails Mazda has offered us $500 dollars towards the repair of the timing chain and $1,000 if it needs a new engine as a good will gesture. They are also insisting we have a tear down of the engine done (approx. $300) to determine what needs to be done. If the car needs a new engine we will be unable to afford getting it fixed and will have to spend the next 4 years helping our daughter pay it off. We also cannot afford to purchase another car.
    When companies like Mazda know their product is defective and fail to issue a recall they are patently dishonest. This is screaming to be a class action lawsuit.

    We bought a car from the Mazda dealership, a certified suv CX-7 2008, a few months later the car started acting up and the engine overheating. We took it in to the dealer and they told us the only problem was that of the thermostat. Thankfully we had bought the extended warranty that covered this. They told us everything else was fine and that was the only problem they had come across. About six months later the car still kept overheating and we noticed there was another leak. We took the car in and now they are saying it was a lack of maintenance from our part, the engine was blown and there was oil all over everything. They told us that if we proved we took care of the engine adequately that our extended warranty would cover it. We did everything that we could and got all the receipts of the Synthetic Oil we had bought, got all our ducks in a row and handed them the "evidence" they needed. Now they are saying that due to the "sludge" the warranty can be void.
    At this point I started doing research based on the fact that we did take care of our car, its oil was changed even before it had to ( A car is a major investment, why would we not take care of it when we're spending $700-900 a month to keep this car). Something wasn't right, I had to put two and two together. According to other Mazda CX 7 Owners their engines started giving out at 40-80k miles. I also talked to a mechanic who told me they believe the engine is overheating due to the turbo in the engine, causing everything to melt. I talked to the main Mazda mechanic about this and they said that they can't do anything but wait and see if the insurance will cover this and replace the engine, he said he knows about the problems people have reported but there is nothing he can do.
    Mazda is definitely a major rip off and SCAM. They SCAM people out of their money by giving them faulty cars that give out way before 100k miles and then tell them it's because they didn't take proper care of their engines. Buyers BEWARE of MAZDA and even their PLATINUM warranty, they will use EVERY excuse to void this! READ ALL THE REVIEWS OF UNHAPPY CUSTOMERS! Mazda is definitely not owning up to this like they should. The MAZDA CX 7 Engine is no good! Lawsuit is on its way!
  • ruby23ruby23 Posts: 3
    Our engine just failed as well!!! A lawsuit is definitely a must!
  • We are absolutely willing to participate in a lawsuit. The dealership that has our car said immediately with no tests that our engine is blown. Clearly this problem is very familiar to them. I'm going to start researching attorneys.

    Omg this is my mazda cx7 problem right now!they told us that we didn't take care of the car. And the warranty says that the canister oil wasn't there thats why the engine got "sludge" thats why it broke down and they don't cover it since it's our fault. How is that our fault? And now they want us to pay $8k for a new engine and i haven't had that car for a year and we still owe $14k? Mileage was 64k when my bf got it and now its 90k and jus suddenly stopped and didn't work? It took them 3 weeks to tell us that the warranty doesnt cover it?why that long? Idk what they did first before they told us that since I was leaving tons of messages to follow up....what should we do?

    I'm very interested
  • I'm very interested as well in the lawsuit! In Aug. 2010 I bought my 2007 Mazda CX7 with 22,000 miles from Carmax. Jan. 2012 I received a letter from Mazda stating they are giving a warranty extension program because of problems with the VVT/Timing chain noise. If I experience a problem please bring to Mazda and dealership will take care of it. 55,000 miles later I noticed the noise. Brought my car to the dealership Mazda confirmed it is the timing chain but warranty will be voided because they found "engine sludge". Mazda recommended I replace my engine and quoted me $10,000! I need to prove to them I was not neglecting the oil changes and maintanence of the car. Since I bought a extended warranty from Carmax and shows coverage I need to give them proof of maintenance. I gave them my vehicle log record I kept from my trusted mechanic. Now I'm waiting for an inspector from Carmax to approve my claim. So now I don't have a car. Mazda and Carmax are playing ping pong. Seems like no one wants to take care of my problem. Mazda knows about the defective engine but does not want to blame them. But to blame my "engine sludge". It amazes me how other owners have the same problem and many are being turned away due to "engine sludge". I am going to talk to a contingency lawyer who specializes in consumer auto cases. Hopefully my case will be taken and I can get some justice or WE as a group receive help. Mazda and Carmax personally need to stop selling CX7s! I also received another letter from Mazda in 03/12 about heavy white exhaust smoke. I really feel cheated by Mazda and Carmax :mad:
  • I spoke with the firm who is working on this and the complaint is in the process of being filed. At that time they will be contacting owners of the CX7 who had problems and ask them to adjoin the lawsuit. I hear and know your frustration. I had mine repaired to the tune of $1800 and had to wait over a month for parts. The extended warranty through Mazda goes to 70K miles. They are probably trying to figure who is going to pay but Mazda had agreed to repair up to 70K miles.
  • Could you share the name of the law firm? If not, how do we make sure we are contacted? We have been without our car for 2 months. Per Mazda Corporate our dealership has to "tear down" the engine in order to see what needs to be done. The cost is $300. After that we will get the estimate. Since our car is well out of warrantee we may end up having to eat the $9000 we owe on the car. This keeps me up at night. Will the lawsuit actually recoup damages? I'm not exactly sure how a class action lawsuit works.
