#337 of 575 My Mazda's Noise by scgal

Jan 24, 2012 (3:33 pm)

I'm a 2007 CX-7 owner (her name is Cici... bought new and have treated like a baby! I drive a lot and have 103,000 miles. It's just started making a high-pitched rattling noise, from the time I crank it until I turn the key off. Does this sound like the timing chain problem you-all have had? This is my 3rd Mazda (had a millinia and tribute before) and I've been very dissappointed with it. The entire air conditioner fell apart at 47k at a tune of $1600 to replace, and some kind of valve went out shortly after that- another $800. Sounds like that's not too bad, tho, after reading some of the other owner's issues! I'd love to sell it but don't want a car payment. :-/

FYI, Cici is the 2.3L DOHC 16 valve 4cyl turbo...

The engines are all the same in 2007. I named mine "misbehaving b****" for sharing purposes here. I can't believe you made it to over 100,000 miles without any problems. You must have gotten the one vehicle off the line that was built with better parts. Good for you. The rest of us are jealous. I would recommend dumping the thing while it still runs and you haven't been stuck with a massive bill to fix it. I stuck over 6k in my car in repairs, and that was only two repairs. I dumped my car after the second mishap which was the timing chain issue. I fixed it and traded it for a German product. Mazda's customer service is absolutely worthless when dealing with the Cx-7, just an FYI. I make it one of my goals everyday to find someone who drives a Cx-7 and warn them to get rid of it as soon as possible. It's unfortunate, but I will NEVER buy Mazda again, nor will I EVER tell anyone anything good about them. If you want to continue to like Mazda, then trade it in for something else. I know they changed the newest models due to all of the issues. You may be safer with that, but I'm going to guess that will end up with it's own set of issues soon enough. Good luck. I'm still waiting for Mazda to reimburse me, but I have a better chance of seeing God walk across the Lake in my backyard.

I bought a 2007 new and like it. a/c locked up under warranty-barely, < 100 mi to spare! 72K now, NO other problems-YET. If I trade it, I know I will lose well over a couple of grand. How can I invest $ in this car and have peace of mind that my vvt/chain and turbo won't fail? I've researched enough to be totally confused! oil catch cans, pop offs, ventilation kits, etc. for turbo. replace vvt/chain before I hear start up clatter or wait till I hear it? Dealer said that if they were bad , they would have failed by now-don't worry. PS-oil changed every 7 to 8K (full syn).

bikerpapa, you best start changing the oil every 3,500-4,000 miles and make sure it's synthetic oil!
Cut your losses, trade it in now. Crossing my fingers that mine will make it till the end of the year as I need to pay off a few thousand off my loan as it's not worth crap right now.

This just keeps getting worse. Also received the recall on the timing chain,
 vvt , and turbo sensor, however, no luck with Mazda or the Extended Warranty company. It is obvious the engine is "cooking" the oil by faulty design and the dozen or so
Technical Service Bulletins published document this as far back as 2009.
 
I will continue my campaign to hold Mazda responsible for "complete" engine failure, and believe this problem could have been avoided if they stood behind their product and their limited mileage special warranty. Letters, calls and a BBB report have been made.

Just got my CX7 back from the Mazda shop yesterday. I've owned it since June 2006. A year ago I had this gut feeling to buy the extended warranty (had 59,900 miles on it). I've been reading all the horror stories, and thank God I decided to buy the Mazda warranty. My timing chain, vvt, etc went out on Sunday - 3 DAYS AFTER I GOT THE TSBs from Mazda with just over 75K on it. They covered it without any questions, guess I got lucky. I always do my own oil changes (Castrol full synthetic, Motorcraft filter). Of the 10 vehicles I've owned (almost all were new first-year models), I have never had so many problems as I've had with this one. I will definitely not buy another Mazda and will advise others likewise. Not just because of the problems, but because of the cowardly stance they have chosen in not repairing major known defects. I urge EVERYONE with CX7 defects to file complaints with the NHTSA.

Exactly the same symptom as mine. We have the extended warranty, and already have had the turbo replaced. Our problem now is that John Kennedy Ford in Conshohocken Pa says the engine needs to be replaced, and they will not honor the warranty because the oil was "low." The oil burning problem was discussed when the turbo was replaced, but they did not address it, and I was adding a quart here and there over the past 9 months or so-
 
Even if the oil was low, an engine simply doesn't work and sound perfectly normal one moment, and then simply destroy itself. While this car has been sitting at John Kennedy Ford for the past three weeks while we are figuring out if a lawsuit is our best shot, we received TWO more RECALL NOTICES from Mazda North American Operations- Disgraceful!

I'm new in this forum and wanted to take a tour on the posts related to the Mazda CX-7, since I'm planing to get one very soon, by next month.
By reading the post above, I'm a little hesitant about the performance (technical) of this SUV. Now, I would like to have some advices from anyone about the Mazda CX-7, 2011.
Wuld you please recommend me to go for it?
 
Thanks

There are now 2 versions of the CX-7, one without the F/awd system and the "turbo" one with. If you think you really need the F/awd system then I would go for the turbo motor but immediately "wire" the wastegate WIDE OPEN.
 
If you lost to much "go" as a result you could have the head milled to raise the compression ratio to the DFI standard of 12:1.
