I took my CX-7 to have it serviced yesterday (regular oil change/transmission fluid change) at the Mazda dealership (always take it there).
I told them to check the car cause we've been experiencing lack of acceleration recently (when going up hill mostly) and black smoke when accelerating every few weeks.
Guy over there calls me mid day to tell me there is carbon residue all over the place so they need to clean/flush that to fix my lack of acceleration issue and I will be good to go. Thats when I decided to do some reseraches and found this thread.
Upon reading the problem about VVT actuator,timing chain etc...I decided to call them and told them about that I also told them I'm hearing some pinging sometimes.
They then decided to investigate further and they discovered the timing chain is at its breaking point.
So they have my car in the shop now and they are contacting Mazda for the repair.
One thing I'm worried about is I waited 10000miles for the last service (guy called me about that asking if I did the service somewhere else and if I have record.)
I dont know if the engine is damaged or what kind of repair need to be done. Will have further info later today.
BTW car have 41000miles
:sick:

My CX-7 has been sitting since last September when first diagnosed with sludge and then the warranty voided at the dealership. They dismantled the valve cover gasket and the sludge is plainly visable through the top of the engine, around the cranks and the timing chain. I had blamed this on poor oil changes but now am realizing there is more than just careless oil changes surrounding this chaos.
Please include me in any distro's concerning this topic and I will begin the letters to every agency I can find an address for. Looks like the BBB, Mazda Corporate and State Representatives are a good start.

As soon as my car was fixed I traded it in immediately!! I will never buy a Mazda again after the way they have treated me and everyone else.
I have also talked to a lawyer who said his friend who deals with class actions is interested in persuing this case.
The dealer provided me with a rental car and the job took almost a week to complete.
I'm very happy with my CX 7 and my dealer (Mazda of Knoxville) has been great; my engine has never sounded as quiet as it does now.
It appears that after being in denial for a long time, Mazda Corporate is finally facing up to the fact that they have had a problem with early production units of the CX7.

Anyway, I am posting again with a question for all of you mechanically inclined people. Our CX7 now has 89k miles on it (SHOCKING!) and we are pretty financially stuck in it by now so I will drive it until the wheels fall off (which may not be too long :-) ). But, here is my question(s), 1) while the manual states that oil changes are necessary at 7,000 miles, I always change my oil at 3,000 miles because first I didn't trust the oil product being put in my car overseas, and second that is what I was taught - 3,000 miles=oil change (old habits!). Could this explain that while I am experiencing many of the other complaints (AC Compressor, heating fan, etc, etc, etc) I have yet to experience any serious turbo lagging (it isn't as strong as it used to be, but who would be with 90k miles?). And/Or 2) While living in Europe we drove in conditions where the speed limits were high or non-existent allowing us to travel at 85+ mph consistently. Could this factor have prevented the sludge from building up? Or is this an old school thought process? I am just curious, since returning stateside 4 months ago, I have not taken it into a Mazda dealer to have it checked because I don't want to be "sold" sludge problem....
On a final note, I am with the rest of you and will NEVER buy another Mazda. The customer service is terrible and the fact that Mazda has the monopoly on their parts turns me off for future purchase - it is a Mazda, not a BMW, not a Mercedes, I should be able to go to any parts store and buy the parts I need to fix the car without being subjected to one of the Mazda mechanics/salespeople trying to invent repairs (but that is and entirely other rant/post).
We took our car in to Rodger Beasley Mazda of Austin about 4 months ago and like everyone else was told that our turbo was out, variable valve, and timing chain needed to be replaced. The cost would be $3750. Our car is only 2 years old with 55k miles. They told us that we needed to show proof of oil changes to determine if they would fix it. We provided them with the oil change documents but they then came back to us with the "sludge" and would not fix it! We have yet to pick up our car from the dealership. Oh and our service manager keeps telling us that our car had to have synthetic oil changes and ONLY PREMIUM GAS, thanks for letting us know. Mazda sucks! I would love to be included in any class action suit against them. I will be contacting the BBB, Attorney General, and whoever else.....
I'm driving an 07 cx-7 which at 55,000 miles developed the "tick" upon start up. Brought in to the Mazda franchised dealer's service department and in one day replaced the water pump, timing chain, vvt actuator, and some rear seals on the drivetrain. No questions asked, no :sludge" issues mentioned, no records demanded-- in fact the only cost to me was for a rental car because the repairs were covered under the Mazda "power train" 5 yr. 60,000 warranty which does not cover the cost of a rental car.
You haven't mentioned whether you bought ar leased the vehicle. This could make a difference on what you owe for an early turn in on an unpaid automobile. I would suggest getting expert legal advice before going any further with these issues.
Best of luck to you, the loyal Mazda owners who placed your faith and large sums of money into Mazda's poorly engineered product. :lemon:
Note: I just checked the BBB AUTO LINE website and Mazda participates in this program. You can even submit your BBB AUTO LINE complaint online at their website or telephone them at 1-800-955-5100 (M-F 9AM- 5:30PM ET). How easy is that folks ?? Good Luck !!

EVERYONE that reads this and has this problem.. My husband called and spoke with someone at the National Safety and Transpo and laid the footwork to forcing Mazda into a recall.. WE collectivly have to file a complaint with them so they can track it.. Good luck all.. Keep those oil change receipts and stay on the phone and computer and keep eye poking cause being on here is good information but will not get anything changed.
The best avenue to make us aware of an issue is to file a formal complaint with us, the NHTSA – National Highway Traffic Safety Administration. Please click on the following link or paste the web address into your browser to file a complaint. https://www-odi.nhtsa.dot.gov/ivoq/index.cfm In the filing the complaint, please have your VIN handy and please include as much detail as possible regarding your incident / experience with the issue.
Also, a class action suit is not the way to go... the atty gets rich and we would end up with some free floor mats...lol. I have done some research on it and it wouldn't be woth it...
Thanks,

Since turbo lag is commonplace, unavoidable, I will assume that is not the "lag" you refer to. You might mean the 1-2 second re-acceleration sequential downshift engine "lag"/delay/hesitation (an upshift followed quickly by a re-acceleration downshift) but due to the serious gain in FE via it's use that has now become standard across the industry.
DBW is being used to ignore the actual gas pedal position, delay the onset of rising engine torque, until the tranny can "settle" in the downshift gear.
"...constantly seeking gears during long trips.."
6(10) speed automatic transmission...? If so just another commonplace aspect. Think of this, a CVT, Continuously Variable Transmission, will always yield the best FE. So these new automatic transmission ECU firmware control systems are programmed to do their very best at emulating the FE performance of a CVT. That, of course, will result in LOTS of up and down shifting due to minor changes in the roadbed and terrain as you drive along, cruising at a relative constant speed.
You have arrived in the future, gas is $4.00/gallon, live with it.
Not by any means saying the CX-7 isn't rife with problems otherwise.
I think it would be unusual if you didn't at least get an engine/transaxle ECU "reflash" when that work was done and maybe even a factory new ECU module. I would never find myself surprised if the operational aspects of any vehicle changed in that event.
The factory would refer to it as a firmware update revision.
If the factory had to replace your engine and turbo it would be a safe bet that they included ANY updates, mechanical and otherwise, that might abate any future "equal" or "like" failures.
Depending on just when the engine and turbo replacement was done you might now be running on/with a much more current ECU firmware version, 2011 even..?
