THE PROBLEMS ARE WITH THE "VERY FIRST CX-7 2007 MODELS (WHICH I HAVE) AND YES CHANGING THE OIL AT 7500 IS WHAT THEY RECOMMEND AS LONG AS YOU ARE USING SYNTHETIC OIL 7,500 MILES ANY OTHER OTHER IS AT THE REGULAR 3500. MAKE SURE YOU ARE ONLY USING SYNTHETIC OIL THIS IS WHAT IS RECOMMENDED FYI.
I USE ONLY MOBIL 1 SYNTHETIC OIL THE VERY BEST OIL. USE TO BE 5000 MILES BUT THE MAZDA DEALERSHIP MOVED IT UP TO 7500. (I DO MY AT 7000 MILES THIS IS WHAT ONE OF THE MECHANICS AT MAZDA DEALERSHIP SAID DONT WAIT UNTIL 7500 DO IT AT 7000. I JUST HAD MINE FIXED THE TIMING CHAIN BROKE WHICH BENT THE VALUES 4 OF THEM CRACK THE HEAD GASKET AND ONE OF THE FUEL INJECTOR WENT OUT WENT TO A VERY GOOD MECHANIC THAT KNEW HOW TO FIX THE MAZDA AND ALSO HAD A SPECIAL MACHINE TO FIX IT. TOTAL COST $3,102.00 --
HAD IT TOWED TO ONE PLACE TOLD ME THE PROBLEM TIMING CHAIN BROKE AROUND 800.00 SO I SAID WELL LET ME JUST TOW IT TO THE DEALERSHIP (NOW THIS IS 2ND TOWING IN 1HOUR) LEFT IT AT THE DEALERSHIP HAD THE TOW GUY GIVE ME A LIFT CLOSE BY, MAZDA REP CALLED AND SAID THE ENGINE IS GONE I SAID WHAT THEY SAID YES, THE FIRST MECHANIC TOLD ME THERE IS NOTHING WRONG WITH YOUR ENGINE IT TURNS. CALLED THE TOWING GUY BACK UP TO PICK IT UP AND TAKE IT BACK TO THE FIRST GUY, FIND OUT THAT THE FIRST GUY AFTER READING THE ISSUES DIDN'T HAVE THE RIGHT MACHINE BUT RECOMMENDED ME TO ANOTHER GOOD PLACE HE RECOMMENDS (THE BEST) THE WENT THROUGH THIS AND THE TIMING CHAIN HAD DID ALL THE DAMAGE ABOVE, HE SAID HE NEVER HEARD OF THIS.
I HAVE POSTED TH SERVICE BULLENTIN IN 2008 RE:TIMING CHAIN PROBLEM, WHICH THEY DID NOT SEND TO ME, ANY ONE WITH MODELS # SO ON AND SO ON, WHICH WAS MINE SEEMS LIKE THE VERY FIRST ONES THAT CAME OUT WAS A TIMING CHAIN ISSUE BUT CREATED MORE PROBLEMS ONLY COVER UNDER THE 35,000. WARRANTY BUT THEY NEVER TOLD ANYONE UNTIL IT BROKE OR WAS OVER THE WARRANTY AND YOU CAN READ SOME OTHER PEOPLE SAYING THEY HAVE DONE ALL THERE OIL CHANGES BUT MAZDA IS STILL TRYING TO SCREW ALL OF US, I AM ONE OF THE ONES WHO ARE WAITING TO BE IN THE LAW SUIT AGAINST MAZDA FOR THESE PROBLEMS THEY NEVER CORRECTED. YOU SHOULD MAKE SURE YOU DO ALL YOUR OIL CHANGES AND SOME PLACE AND KEEP ALL YOUR RECORDS BECAUSE MAZDA IS USING THIS FOR THE PEOPLE WHO HAVE DONE IT THEMSELVES. IF YOU DO IT YOURSELF WHEN YOU BUY THE FILTER AND OIL MAKE SURE THEY PUT THE VIN # ON THE INVOICE FOR YOUR RECORDS THIS WILL SAVE YOU A**.
GOOD LUCK CHRISTINA

Driving a 1st generation 2007 CX-7 (55,000 miles) and yes, just had the timing chain, VVT actuator (keeps timing chain tight) water pump, and driveline gaskets replaced. Mazda power train warranty covered everything except a rental car for one day. Upon a cold start, was hearing a little "chain rattle" and was fortunate to bring the cx-7 in for repair before catastrophic engine damage took place. I now believe al the 07's need this repair once they reach the 40~50 thousand mile mark. Hopefully, these new parts should last to 150,000 miles?
As far as oil changes, the Mazda dealer now recommends 5000 mile intervals where they rotate the tires and perform a few minor checks for $59.99 plus shop supplies, environmental fees, and tax.Comes to about $72.00 total unless you use an internet dealer coupon from time to time. The dealer does not recommend synthetic oil, they use a half syn blend which they claim works just as well.
After the new water pump, timing chain, VVT actuator, front end alignment and new tires, (set for 37 psi) now achieving about 21 mpg in city driving using premium 91 fuel. The Mazda Dealer says the 07's cannot use regular on a steady basis--the turbo is designed for high octane fuel to achieve maximum performance and mileage.

You never mentioned how many miles are on your 2007 cx-7. The MAzda power train warranty clearly covers the timing chain, VVT actuator, water pump and most all internal engine parts to 60,000 miles or 5 years from your in service date. How come the dealer didn't cover this under warranty?

Would check alignment // keep tires at 37 psi // replace air filter. Driving an 07 cx-7 w/ 55,000 miles. Getting an extra 2 miles per gallon after alignment. :Last fill-21.3 in town-regular driving. Best ever so far on the road was 24.5. (THis was when the front end was out of alignment)--and haven't done any serious road tripping since.

I would get rid of the CX 7 as fast I could. I just spent $6800. for a used engine for my 07. I also just traded it in for a Toyota Rav4. At least they own up to their problems.
Mazda's owners are crooks and hopefully they will pay for this mess soon.

Why didn't the standard (3 yr. 36,000 mile) or pwertrain (5 yr.-60,000 mile) warranty cover the cx-7 engine issues?

Same story we all got. Engine had sledge in it. Even with oil change receipts it did no good. It is a horrible company to buy a car from.

That really seems amazing. My dealer gave no hassle at all. Didn't ask for any oil change documentation. No babble about sludge. Just brought the car in and upon examination without my asking, replaced the VVT actuator, timing chain, water pump and some rear driveline gasket seals. Only out of pocket charge to me was for a rental car which apparently is not part of the "powertrain warranty".
The selling dealer can make all the difference in the world. A potential customer should really ask the service department for some referrals before deciding to purchase a vehicle at that particular dealership regardless of the selling price. I don't mind paying "retail" as long as excellent service is received.
Apparently, even if I paid a couple thousand more for my Cx-7 than you did-- just made up for it by having critical repairs covered under warranty. (which in theory--should have been covered for all of us-no matter what the ending price of the cx-7 happened to end up at.)

yeah only if they had some kind of coverage in case the engine goes bad around 30000 miles it wouldn't be so bad i don't care about any excuses a car engine should last longer then 30000 or 35000 mile they junk period.

I lease my 07 CX7 it only has 32,000 and i started having problems with loss of power every once and a while. I thought I was just getting bad gas (I always use 91) but then after a while we could smell a weird smell coming from the tailpipe so I had my wife take it to the dealer. It's been there for a week now, they even had the district big wig look at it and their conclusion was it came in very low on oil and we have sludge so It must be from from neglect (I just had the oil changed and that smell was it going through the oil some how). Now they say I need a new engine and turbo and it will cost $7000 give or take. I hate Mazda!!!! How does one go about starting a class action lawsuit? I would rather give my money to a lawyer then fix that POS.
