Ive had the same issue, presented this Service Bulletin to Mazda and they don't care. The corporate customer service rep actually said, "Too Bad." Thanks, Paul. you ASS!
here is my story:
I have found 100s of blogs from 2007 CX-7 Owners just like me. My Story:
Purchased a used 2007 CX-7 with 31,000 miles (still under warranty, allegedly). Drove it for four months to the day, 34,000 miles on it now. White smoke, knocking engine. Mazda requests past oil changes which I have one. Mazda presents me with a $4,100 estimate to fix replace the turbo, engine repair and timing chain. Notice that in January of 2008, Mazda North American Operations put out a Service Bulletin No. 01-002/08 describing this exact problem. However the bulletin clearly states "Only to verified customer complaints on vehicles eligible for warranty repair." GREAT! it can be fixed, Mazda says so! Oh, what? Not so fast. Mazda tech says there is a sludging problem therefore VOIDING the warranty. But the service bulletin says it can be fixed due to my complaint. After further research I discover that the turbo system in this car has an engineering problem causing WAY! to much heat for normal use, therefore burning oil, therefore causing sludge. Mazda uses this "evidence of sludge" caused by them! to claim that the owner did not maintain their vehicle, therefore "your warranty has been voided." Mazda is trying to avoid a Recall on this for obvious costly reasons. I have contacted an attorney and he is currently working on my case. Until then I have a 3,000 pound paper weight with a $15,000 note. Thanks Mazda.

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.
#98 of 608 Timing chain problem
Jun 16, 2010 (2:04 pm)
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.

#101 of 608 2008 vs 2007
Jun 20, 2010 (6:32 pm)
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.
