I have started my own post on Edmunds #103. Please review and give me you thoughts. I am hoping to pressure this claims adjuster with info such as your blog. Any info you can offer is appreciated. my email is eward@apexfoodgroup.com. tks
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?
Let's keep the discussion here so everyone will benefit.

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 - 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
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
Thanks!

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.

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!
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 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.
This is also why you will NEVER see an Atkinson cycle engine with a turbocharger. The Atkinson cycle engine gets it extra, extreme, fuel efficiency via using more of, virtually ALL of the energy of combustion, in pushing the piston downward.
That means that the turbine section runs at an EXTREMELY HIGH TEMPERATURE, generally in excess of 1500F...!!
First, when you switch off the engine that HEAT does not majically go away. So it will quickly HEAT-SOAK the drive shaft, seals, bearings, and most importantly the lubricating oil "trapped" within the turbo upon engine shut down.
It is for this reason that many more robust turbocharger designs will actually provide some type of "after engine shutdown" cooling method for the turbine area and bearings. An electric oil or water pump that runs for 10-15 minutes after engine shutdown depending on the cooling method.
But the really BAD news comes when the SUPER-HEATED engine lubricating oil, used for lubricating AND COOLING of the turbo bearings, is trapped within the turbo after engine shutdown. It gets COOKED, LITERALLY..!
Engine SLUDGE...? Now you know the source.
The turbocharger very likely failed due to the "coking" of the turbocharger lubricating and cooling oil. It is entirely possible that the "coked" (sludged up) oil resulted in BLOCKED oil flow passages not only within the turbocharger but also somewhere within the engine itself.
A N/A DFI engine could run with a 12:1 compression ratio on regular fuel, with intercooled boost <10:1 is more likely.

Most of us know of the condensor being part of the A/C system, mounted in front of, just forward of the radiator, are you using the correct term...??
HUMMM YOU GOT A POINT WITH THESE CRAPPY A....CARS WE ARE DRIVING BIG NOTES AND BIG MECHANICAL BILLS WHAT A NIGHTMARE, SO IF IT IS CHECKED WEEKLY EVERYTHING IS OK DONT THINK SO.. :lemon:
After reading all these posts......don't think I would buy a used turbo equipped car and with my last post, was just bringing up the issue of owner basic maintenance....not a cure all....but can prevent some problems.
The mules, yes, but daily.
I did change my oil and performed maintenance as stated by the maual.. I am not a mechanic and refuse to check a new car every week.. My husband is too busy defending our country so he cant check it..To me that is putting reliability in question.. We have a Toyota Tundra that has as many miles the Mazda and not a single problem.. We change the oil, normal maintenance and that is it!!.... Honda Pilot 90k miles on it at trade in.. Not a single issue.. Never checked the belts weekly and so on... Oh, but wait.. Honda did that the since enough to recall items when the thought they were an issue.. It was a first year model also.. NO problems...
Must be cause of all the weekly checks I didn't do or all the non-maintenance I didn't perform..LOL
You better believe that when the Mazda comes back I will be right back at Honda begging for forgiveness and buying another Pilot...
Hi fonefixer! You could be right. The key word here is "NOW" and it is missing in your statement! I would ask: ... how many new car owners NOW can drive 100,000
miles w/o major breakdowns?
Here is my story. I purchased my first Mazda 626 4 cyl 2.0 in 1995. In 2008 I sold that car (176,000 miles) to my co-worker. His son still drives that car! It has ~230,000 miles for the time being! I did not have any breakdowns AT ALL! Just regular maintenance. Yes, I did check that car weekly between scheduled maintenance just to make sure that everything was OK. But it was practically useless! Everything was fine every time I looked under the hood.
IMHO, Mazda is a very reliable car! But CX-7 w/Turbo in particular is A NASTY JOKE! All that MTO (Mazda Turbo Ordeal) prevented me from buying a new CX-7 last year. However I am looking at CX-7 non turbo engine. It has been a year since that model was released. I did not find any major complaints so far (fingers crossed).
