#329 of 577 2007 CX-7 GT AWD Turbo Replaced by ynot411

Jan 11, 2012 (8:05 am)

Just had the turbo replaced at 64,850 miles today. Brought the CX-7 in for an oil change and to diagnose a rattle-ling/clunking noise when accelerating on 01/02/12. I have the Mazda Extended Protection Plan (Easy Care) which I had to fight tooth and nail to get them to cover the turbo replacement. After 9-days of proving that my records and the Mazda Shop Foreman's observations were correct on having no signs of neglect MEPP (Easy Care) approved the claim. However, the car rental exceeded the max. 6-day allowance and the diagnoses labor exceeded the 2-hour labor allowance. It took me to contact the CEO of Easy Care to make things right since it was his company that prolonged the process. Will be picking up the car this afternoon to see if issues have been resolved. Cosmetically the CX-7 is appealing but reliability and dependability is awful. Let a lone dealing with MEPP is a huge headache as well.

I'm in sort of the same sinking boat- About a year ago, under my long term warranty, the turbocharger was replaced. They mentioned nothing to me about timing belt issues. A few weeks ago, a tapping whining sound, and loss of power. Had it towed to the dealership, John F Kennedy in Conshohocken Pa, and was told engine needs replacement, and it is not covered because there was sludge in the oil pan- I have maintained the cars oil changes, and told the mechanic last year when the turbo was down that I was constantly adding a quart here and a quart there, because of the oil light. Nothing was done to address that, and now they want $9000 to replace the engine in a 5 year old car-
 
Does anyone have any advice on how to best approach This? We have been on the phone many times with the dealer, Mazda, and the factory rep, and they are not moving an inch-
 
Thanks!

My daughter's CX-7 was diagnosed with these problems and Mazda factory told her the same things, engine needs to be replaced, 8K cost.
I knew the turbo was burned up, bought a replacement, with the assistance for tech info from Blast Performance in Quebec, we changed the turbo, installed a re-routed oil supply line and the car now lives again.
It can be done alot cheaper, and easier. total cost about $1500 parts and labor, I did some of the engineering.
If you are in the upstate NY area and/or want to contact me I can give you the info to save you the headache and money.
My wife and I bought out her mortgage on the CX-7 because she didn't have the money to fix it, and gave her our TDI.

Note* These problems are not about changing the oil at the correct interval, they are from heat at the time of shut-down "coking" the oil in the turbo housing!
The best thing you can do to alleviate this is to let the engine idle for up to three to four minutes when you pull in to park, you can do this by sitting in the car or by installing a "turbo timer", all the tech kids racing and tuning these do it to extend the life of their equipment.
You also must use the best synthetic oil you can find, Valvoline, Red Line, Amsoil are some of the best, 5 or 10W-40.
My problem with Mazda is the lying and selling high tech cars and not informing the purchasers of the need for specialized handling for their equipment.

#334 of 577 Turbo Sensor Replacement just a quick fix?????? by ckboles

Jan 20, 2012 (1:38 pm)

The more I look into the CX-7 engine problem, the more questions I have.
 When my turbo sensor was replaced at 62,000 miles by an extended warranty company, would the timing chain / oil sludge issue be obvious?
 I received a diagnosis of complete engine failure just 7 months after the turbo sensor was replaced, however, I feel like the warranty company may have just done a cheap fix last year, instead of replacing the engine.
Of course, the extended warranty company won't replace my engine now...citing "sludge", nor will they release the photos or report from their adjustor.
Fighting everything now. I'm amazed by the "it's not my problem now" attitude of the extended warranty company. My car was well maintained and everything documented.

I had the same problem with the timing chain, VVT actuator. We bought the replacement parts from Mazda and my husband is doing the work, but we are still having problems with this vehicle. Today, I got a letter from Mazda that says they know they have a problem and will extend the warrenty to 70,000 miles. Mine didn't break until 80,000 miles so I am screwed by Mazda yet again.

I also received the letter today regarding my VVT/Timing chain, which is great because I've had both replaced and the VVT is still rattling like crazy and the dealer just says "that's how fuel injectors sound, dear." Yes, I'm a girl, but I'm pretty sure my car isn't supposed to shake and make people around me go "the hell?" when I start her up.
Also in the envelope was a happy little letter telling me they are extending warranty coverage for "heavy white smoke coming from the exhaust due solely to overheating which leads to leaking of oil onto the turbocharger and turbo failure." If you have white smoke and the turbo hasn't failed (which is their way of doing a cheap fix right before everything breaks) they'll add on a ventilation system. If you have white smoke and your turbo is cooked, they will replace the turbo, as long as you're under 70,000 miles and 7 years. I had to replace my turbo back in July, so now I get to fight with them for reimbursement; I am hoping that since they partially covered me as I was 100 MILES outside of warranty this won't be too hard, but I think I'd rather have a colonoscopy without anesthetic.
For all who are still having problems, the warranty extension cover CX-7s made between 2/14/06 and 7/1/08, Speed3s 6/28/06-6/30/08 and Speed6s 8/4/05-6/30/07. Good luck, we're all in this together.

#337 of 577 My Mazda's Noise by scgal

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...
