    Driving a 2007 Cx-7 with 60,000 miles. Noticed a slight , but not loud "rattling noise" upon cold start up and brought car in to the franchised Mazda dealer service department. Dealer replaced water pump, timing chain, VVT actuator, and rear seals in the drivetrain. Only cost to me was a rental car for one day. Covered under 5 year /60,000 mile drivetrain warranty. No hassle about "sludge" or any other issue with previous maintenance such as oil change receipts. Dealer does highly recommend saving every piece of maintenance records for possible future warranty backup reasons. A huge difference in service department methods of operation!

    I just spent $6800. to have my 07 Mazda fixed. I then dumped it at a Toyota dealer for a new Rav 4. Unless Toyota is man enough to fess up to their issues. Can't say the say at all for mazda. What a bunch of loser! I will clap the day they are finally caught over ripping all of us off! Add me to the suit. I have the old part in my garage waiting for a lawsuit!

    Guys, it sounds like all the problems start around the 35,000 mile mark. After reading all of this I also dumped mine on a Buick dealer. Now have a Lucerne. It scared me when after just a little spirited driving, it smelled like it was about to burn up. Sorry for the poor sap that buys it.

    My 2007 CX7 has 59,300 miles on it. It is in the shop getting a new ac compressor, and check up before the powertrain warranty is out. About 4,000 miles ago I brought it in for engine noise and they replaced the VVT Valve. They did not replace the timing chain or water pump like many are saying. They did cover the VVT valve under warranty. Will replacing only the valve prevent the timing chain from breaking, or should I replace it now? Any thoughts appreciated.

    I still don't think the engine sounds right, the check engine light was on and off. But all they could come up with is a throttle sensor is bad, and the ac compressor was ready to go out, none covered under warranty with a $1,000 estimate. Sorry for all who experience major engine damage. This is all totally wrong and Mazda needs to come clean on all these issues, good luck with the lawsuits.

    well at this point my mechanic and I have torn this engine down. He's baffled at the way they've designed the thing. He is basically saying this is a disposable engine. it hasn't been built to be torn down. there are elements missing in the design. We are photographing and documenting everything we're doing.

    If you are hearing any ticking noise at all you better take it back because this is one of two chains in the engine. the actual timing chain did not break in mine. the secondary chain broke. I don't know what this chain does but it came off the cogs and bent the timing chain. there are also bulletins from Mazda recommending to change parts of this engine. much like a recall but without the liability. I am very disappointed in this company. I always thought they were a good company but it turns out they are just like all the others.

    I'm a little like a pitt bull when it comes to things like this and I plan to do something about this.

    Good luck
  • i have had problems with my mazda would be happy to help with lawsuit any way i can turbo went out at 39000 miles and mazda gave me the same sludge in engine routine and won't fix my car

    I bought a 2008 used last winter with 12K miles. I called Mazda to get service history and they had history of an oil change at 7K. I immediately had the oil changed at 12K and have changed every 3k since. My questions are whether the 2008's have actual improvements to the engine and whether people with denied claims have similar oil change history available when their warranty is being denied.
  • dj119dj119 Posts: 10
    I think all of us have oil change records. Mazda doesn't care. It still uses the same sludge excuse because they know they have a huge design issue. The need to be held accountable just like Toyota was.

    Hello - I have been with out my CX7 (08) for 9 days now. The Turbo has failed. I have honored the request for service history and they will allow the repair of my car on one condition. They are sending an independent claims adjuster to the dealer to visually check the oil line to the Turbo. If he sees excessive SLUDGE, they will not repair my car. What is exessive SLUDGE - I am assuming from all the forums that it can be whatever they want so as to facilitate their need to refuse repairing any MAZDA. I have 62500 miles currently - at 57K the timing tensioner was rattling and I had this repaired (took 9 days as they kept misdiagnosing the part) - at 60K the right front oil filled motor mount went out. I have asked to be called when the adjuster arrives for inspection. I will be there for his evaluation - camera and records in hand. Wish me luck and say a prayer as well. Anyone who has or is going to start a class action law suit...put me on the list. I am ready to join the team. tks

    We had the exact same thing happen to our Mazda CX-07 and ended up having to buy a new engine - even after connecting with Mazda corporate. Now, we have just had to replace the "turbo" and the car is still not right. We had an outside company do the turbo work but the independent repair shop said there might also be a catalytic converter problem. It is now at the dealer's and they want $500 just to diagnose the problem.

    After spending upwards of $7,500 on this car, we are most interested in a class action suit. Clearly, this is a known Mazda problem since many others have had the same experience. How do we join together and get results? We have now been without our car for about 8 weeks and there is no end in site.

    Has anyone out there had any luck with going to the media or breaking through Mazda's corporate brick wall on this?

    My husband bought a new 2007 Mazda CX-7 and has the engine problems you all are describing. Of course, they blamed it on severe engine sledge and maintenance neglect... very frustrating as we have documentation of regular maintenance and oil changes. Rather than pay the $7000 they quoted him for a "re-built" engine (whatever that means!), we found "Autowise" in Indianapolis, where a mechanic within 10 minutes told him it had to be timing chain, which then caused another slew of problems, and will fix it and stand behind it for $2,500. This all just surfaced this morning, and of course I went straight to the internet thinking there has got to be other stories out there - and of course there are plenty! We will be sending all of our maintenance documentation into Mazda USA, and will send copies to the Dealer and well as the Federal Govt agengy who oversees this. If there ever is an engine recall, we will expect to be reimbursed.

    Sorry to everyone who is experiencing the same thing. I know we won't be purchasing any more Mazdas... its too bad for their dishonest business practices.

    Hello
    just an update - the independent adjuster reviewed the turbo oil plug that feeds the turbo. It was of course full of SLUDGE. The extended warranty company denied to cover the repairs. I have a call into Mazda corp...they say they will review and let me know if they can help.
    they say i should have been changing my oil at 5000mile intervals (review your owners manual schedule 2) they warranty contract is what i looked at and it states 7500mile intervals....who knows what you are supposed to do....i am probably going to have to repair the car at my cost....it seems we are all in the same boat.
    i hate this hopeless feeling...you trust in someone or something and they just leave you hung out to dry. Helpless in Harrisburg

    This is very disturbing information. I am reading more and more negative things about Mazda and especially the CX-7. I use Pennzoil Platinum Full Synthetic 10w-30w. It is changed at 7,000miles or 6 months which ever comes first.

    We took a trip of 1800 miles in the northern ozarks from SW La. total gas milage overall was 23.6mpg. with a high of 26.4mpg and a low of 20.5mpg. We only have 15,000 miles on the CX-7, my wife's car and she prefers to drive our 2006 RTL/SR Honda Ridgeline.

    Hopefully we will continue not to have any problems, there are a lot of CX-7's in our area of 200,000+ people in SW La.

    I would suggest that you increase your oil change to 3,000 miles and never go over that amount. you need to take the car to mazda and do no tell them you waited 7000 miles your first oil change. have them check your car out and document the procedure. I loved our cx 7 but this car has severe problems, mostly flaws in the design. my advice to you if you don't absolutely love the car is to trade it for a Ford. The Ford Edge is a better car and the company would never do this to their clientele. If you find yourself in a bad situation with the car please contact me and send me your e mail, we are combining our efforts to sue Mazda.

    Waste of time, money and oil in my opinion. I follow the owner's manual recommendation and I drive them forever.

    On my birthday, the car died suddenly late at night while traveling on road late at night. ..towed to dealer, who asked for my receipts in order for the warranty to pay...guess what, they said I had "sludge" and refused the claim...Now an ERNORMOUS bill they want me to pay out of pocket.. I want to join the lawsuit NOW!

    I am waiting on pins and needles. My cx-7 is with the dealer for a couple of weeks now and we are waiting to hear about the warranty coverage, if any. What kind of work did they do and how much, if you don't mind me asking. My dealer hasn't given me a price yet.
  • warde333warde333 Posts: 7
    I am having to have the Turbo replaced. the dealer quoted me $2159 + tax. Have they asked you for your maintenance records?
    If you did not get it serviced at the dealer regulary(7500 mile per the extended service contract company or 5000 mile per the owners manual and reccommended by Mazda customer service - due to my driving habits of higher than normal milage) you may have issues with the warranty coverages. I truely hope that you do not. I would definitly urge all owners of this vehicle to change the oil at 5K or less regularly and even then i question wether or not they will cover the repairs if they deem that sludge was visible upon inspection of the damaged part. Good Luck.

    I am reading all of these comments and my story is pretty much spot on with everyone else. Anyone know if there is some sort of lawsuit in the works?
    I was quoted $8,000 to completely replace my engine...and I still owe $8,000 on the car. I am royally screwed. Below is my compaint I filed with the NHTSA if anyone is interested.

    I have a 2007 Mazda CX 7. I bought it new in February of 2007, so the car is only 3 ½ years old. Two major things have happened to my car within the past two months…one of which seriously put my safety in jeopardy.
    I will start with, two months ago, my air conditioner went out completely. The air compressor had to be replaced. Then, about a week ago as I was driving down interstate 75 (going about 70 mph), the acceleration on my car completely went out. Luckily I was able to get over the 5 lanes of traffic and pull the car off to the side. After I turned my car off, it never cranked again after that. Long story short, I took my car into Jim Ellis Mazda in Marietta, GA and they said there was internal damage to the engine and the engine would have to be replaced completely. They couldn’t even tell me what exactly went wrong or really diagnose the problem for me. They just said the engine needed to be replaced.
    The kicker to this story is, when I went in a couple months ago to get my air fixed, I asked them to take a look at the engine because I thought it sounded loud. The said it was completely fine and nothing was wrong with it. Well…two months later this happened.
    I have talked to Mazda Customer Service and they will offer NO assistance for fixing my car (which I have been quoted $8,000 to fix!). I was told that Mazda had reviewed my case and I was declined because there was sludge around the engine, which apparently gives then reason for no assistance. They said that is proof that my car is not maintenanced on a regular basis, however I have documented proof that it is maintenanced regularly. They just didn’t seem to care.

    I did want to followup with questions...My car expeirenced the same loss of power when the turbo failed also made high pitch whinning noise. Is it possible that when this caused by an internal engine failure that caused the turbo to go? I had this in for a timing belt issue just 5K miles before this. The dealer had it a week and kept saying they had diagnosed incorrectly. I have a copy of the dealers list of repairs. They list that they replaced the timing belt tensioner. In talking to the Mazda Extended Warranty customer service rep yesterday - He stated that his info in the computer states that the delaer reported fixing a serpantine belt and the billing they paid out to the dealer was not the same for parts or labor....Hummm. How can they reflect different info than what the dealer gave me as a receipt?? I are really worried they are going to fix the turbo only to see the engine is gone as well. Or the engine will go out when I drive it off the lot. Can anyone offer me any advice? tks
