Do not ever buy a Mazda of any kind. Their customer service and employee people skills are the worst of any king of retailer of goods I have ever experienced. They will admit that they had a flaw in the CX7 and thus many customers got stuck with huge bills and a worthless car. Me for one. I am still buying off the $6800. extra I had to borrow to have a car still under warranty fixed. Trust me, I sold it the say I got it fixed. Stay away from Mazda cars. They are big time trouble.

Given the design engineer, engineering, sharing alliance between Ford and Mazda one has to wonder what the reliability might be for the upcoming EcoBoost 4 cylinder to power the new F/awd Explorer. Oh, sorry, like the non-turbo 4 cylinder CX-7 the 4 cylinder EcoBoost Explorer does not have the F/awd option.
Maybe that's the Ford/Mazda answer, less overall "stress", no F/awd capability, on the Explorer's turbo 4 cylinder drive train to "improve" the reliability.
#327 of 611 Mazda CX7 '07 Engine Shot
Jan 04, 2012 (10:28 am)
Guess I've joined the club.....engine shot at 72,000 miles, extended warranty will not cover due to "lack of maintanence" even with receipts. Since purchasing gently used in 2008, 3 sets of tires, no power, needed turbo sensor, clicking noise, sparks coming out of steering column, bad / foggy headlights, windshield seal causing major passenger side leakage, sludge and metal in the engine, whirring noise lasting for 3 minutes after shut-off. About $10,0000 to fix replace engine.
Question: Should the dealer / warranty company have noticed the timing change issue when they replaced the turbo sensor? I have documentation stating it was bad from an independent, reliable mechanic, Mazda dealer did the warranty work to replace turbo, but said nothing about the timing chain and / or sludge. Also: is it reasonable that sludge would have been found in engine when the turbo sensor was replaced?

Who paid for the repairs? You or the warranty company? Same exact problems, don't think it makes sense to fix this car if it's not covered by the extended warranty, in dispute now.
Reported to NHTSA also.
#329 of 611 2007 CX-7 GT AWD Turbo Replaced
Jan 11, 2012 (7:05 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-

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 611 Turbo Sensor Replacement just a quick fix??????
Jan 20, 2012 (12:38 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.
