Mazda CX-7 Engine Problems

  • I had a very similar situation; I ended up getting a Toyota Prius, and had to borrow money to pay what I still owed on the Mazda CX7 , which was like 11k at the time. I sold the piece of junk remaining of CX7 to a company that buys used cars (good and broken) for auction, and I was able to get $6,500 for the CX7 with broken engine. I suggest you try that..

    FOLLOWUP: Today, 8/9/2012 I took my CX7 to a dealership near my office in Broomfield, CO because it was more convenient than taking it to the one near my home who did the original engine replacement. The car had check engine errors (on my newly replaced engine) which have apparently been determined to be related to the VVT problem that caused failure on the original engine. The replacement engine was a used/rebuild engine with 27K miles that the 3rd party warranty company had obtained and shipped to the repairing dealership, not a brand new engine from Mazda. I had contacted both the warranty company and the dealership imploring them to research whether the replacement engine had gone thru the TSB repair process so I wouldn't experience another failure, but they neglected to do so, instead relying upon the 12 mo parts/labor warranty on the replacement. The car has clocked an additional 11K mi on top of the 27K, so now we're looking at an issue at 38Kmi! However, here's what kills me.. the third party warranty co. will not authorize a rental until repairs are officially authorized and they know that the dealer will require the car overnight -- and of course they were unable to reach a decision today. So since they didn't say I couldn't drive the vehicle, nor did they tell the dealership the same - I opted to pick up the car and drive it round trip another 170 miles and will drop it off again in the morning. I can play the game too... at this point I halfway hope the (expletives of your choice here) engine blows up again, even though it would be a major inconvenience to me. Fingers are crossed at this point.
  • If there ever is a class action lawsuit, contact me. I want in. On a '07 cx-7, I'm out 2vvt's and chains (a year apart), a turbo, a top end (values, ect), and now a complete engine.

    Yes---if anyone is starting a class action suit, I'm in. Out of pocket over $5000 and I have all the parts that were taken out (timing chain, VVT, etc) plus photos showing no sludge. Plus, there is FORD engine in my car, not a Mazda engine.

    Mazda has made a huge customer service mistake by not recalling or repairing the engine problem. I stop people driving the CX 7 and tell them to dump it before they get screwed also. They have thanked me profusely for letting them know.....hope their car makes it.

    I have a 2011 CX7 GT Turbo with 5,000 miles. Have filed all problems you are experiencing and more with Mazda and THE NATIONAL HIGHWAY TRAFFIC SAFETY ADMINISTRATION. Contacting NHTSA only requires a simple telephone call. I reported that I get a loud banging when my air conditioner comes on and that this banging frequently occurs when I quickly accelerate to over fifty mph. Believe me I am looking for an attorney to take on a class action suit. My family is trying to find one knowledgeable enough to really get Mazda's attention. Please file everything you have experienced pertaining to your CX7 with NHTSA, this can be highly instrumental in a class action suit. Lets make Mazda take some notice and stand behind their products. The NHTSA phone number is 1-888-327-4236.
  • My 2007 CX7 was purchased in Dec 2006 and I did take many long trips so my mileage is higher than most. Still, I intend to pursue legal action against Mazda and in general research have found hundreds with the same issues. I, like many, know I had regular maintenance performed and my car was babied to say the least. I will have a facebook page created in the next several hours and will send a link for all to post. I hope with the newly created page, these forums, and a petition we can make a difference. The Mazda CX7 is not a cheap car and repairs are definitely not cheap, so why should we settle for cheap quality?
  • TO EVERYONE WHO HAS EXPERIENCED LEGITIMATE PROBLEMS WITH MAZDA CX7 ENGINES, TURBO & AC FILE COMPLAINT DETAILING CIRCUMSTANCES WITH NHTSA (1-888-327-4236). MAZDA IS A HUGE CORPORATION WITH A VERY GOOD LEGAL DIVISION. IF YOU WANT TO GO AFTER MAZDA YOU NEED TO ESTABLISH A VERY SOUND CASE. I KNOW FROM MY BACKGROUND FILE WITH NHTSA. PILE UP THE COMPLAINTS (LIGITIMATE ONES). YOU WANT TO START A CIVIL SUIT GIVE DOUCMENTED EVIDENCE.
  • The turbo charger in my 2007 CX7 has to be replaced @ only 78k miles for $2K (dealer's price) I filed a complaint with Mazda and the DOT NHTSA. This car has been nothing but a costly lemon- with most repairs related to the engine. I am following these threads to take part in any legal action similarly situated Mazda owner may pursue.
  • hi people, just joined the club- have all service records on time-bought car with 21,609 miles, have sludge build up-suggest replacing timing chain and turbo-$4600.00-Luckily bought through carsense, engine for life guarantee-PLEASE REGISTER ALL COMPLAINTS WITH http://www.nhtsa.gov/ SO WE CAN MAKE THEM PAY UP FOR THIS. Don't bother calling Mazda, their trained phone operators will put you on hold forever. It's they're arrogance that upsets me, that they can blow people off so easily- A CLASS ACTION LAWSUIT WOULD COST THEM MILLIONS,please file with NHTSA.gov

    After replacing the timing chain, turbo sensor and VVT Actuator, my Mazda is running like a dream. The zoom zoom came back, and the car is performing better than ever!!!!!! A good mechanic makes all the difference!

    Now, I'm still out the $5000 from this repair, and I'm hoping Mazda will reimburse me. Car is getting traded in, as I need more of commuter car, however, I can sell this car with confidence now!!!!!

    Wish me luck with Mazda.............................................. :shades:
  • Aug. 21, approximately 80K miles, felt a slight jolt @70 mph. Engine lost some power (could not maintain speed), then quit altogether. Had car flatbedded to dealer (who has performed ALL recommended maintenance since Day 1). Several days later, dealer stated remanufactured engine would be required at $6400. I told them that, as this is a known problem, Mazda should step up and help. Mazda refused, so I'm having my engine rebuilt by an independent shop at almost $2000 less! No more Mazda's for me (this was my first) and I AM interested in a class action suit if one commences. I have ALL my records. A timing chain should not fail at this mileage if the engine is properly designed.
  • Yeah....Mazda has been incredibly selfish and are real jerks in regards to the CX7. Still fighting for my $5000 private repair back. Just yesterday, I purchased a Mazda 3, because a Mazda dealer is the only one who would pay fair trade in value for the CX 7.

    The latest joke is I again asked them for $$ back, and was offered a $100 gift certificate!!!!!!!!

    I swore I would never get another Mazda, however, the 2007-08's were just bad cars. Everyone else I know with a Mazda 3 or 6 has had no problems.

    Let's see what happens....I am shipping the chewed up timing chain, the 1 year old turbo sensor and assorted other repaired parts to the Recall Department......I have photos and even had molds made of the bad parts so I can keep fighting for my money back.

    Good luck, and don't give up......forget a class action suit, just work on getting your out of pocket expenses back!!!!!!!!! :shades:
  • For those who are interested, please contact me. This problem is being solved (not by Mazda, obviously). Thanks. V.
  • I'm listening......if you can come up with something, let's do it!!!!!!!

  • contacted nhtsa, filled out ppwk sending 9/17- my response that I finally got from Mazda was since I bought the car with 21,000 on it , they speculated the previous owner never had a oil change- their customer service is the worst-they call late, she didn't clearly identify herself- I had to dump my CX7 at a loss-went with a honda crv-never again will I go to these idiots-Had a lemon law lawyer lined up for the case, but when I got rid of it the case went too! If someone knows of a suit please post case or lawyers name..
  • I also am the owner of a Mazda cx7 that has the same problem , can't afford repair, stop home base business and I've been renting cars to get to work because I live so far from job to be without a car. I've also filed a complaint with the nhtsa. I've contacted several law firms that deal with product liability but none are willing to take the case (non injury) so if you have someone I'm very interested :mad:
  • Hello CX-7 owners. My 2007 CX-7 GT AWD is being serviced today under the extended warranty for the vvt actuator and timing chain. Dealership said they'll service the turbo as well. Anybody had this type of service done? Did you notice any difference in performance? Just wondering if after all these services, will my CX-7 be reliable or should I flip it and buy a new one?

    Just bought it a month ago used coz I liked the styling and the turbo was fun to drive. But after reading all these horror stories, I've been thinking really hard about it and somehow losing sleep over it.

    Appreciate all your comments and advices you wonderful CX-7 owners.
  • You basically answered your own question .... what you have read is all very true and very expensive to each person who's owned/still owns their CX-7. Dumping mine was the best decision I made! I will NEVER own any Mazda product ever again. Everyday consumers wouldn't get away with treating people the way Mazda has, and yet they continue to steal from people. If I didn't know better, I would think the Government ran Mazda. Maybe? Dump your CX-7 as quickly as you can! Don't fall for Mazda's new versions or even their CX-5 or whatever it's called, because its only going to be a problem in time.
  • BS! Don't EVER listen to your dealership ... I learned that the hard way. I also caused a scene at mine after being told the same thing you were, and then a couple of months later, the car quits on the freeway in a snow storm because the timing chain broke and everything seized up. It gets better ... because the engine keeps running for a short time after the timing chain breaks, it bent valves and several thousands of dollars went it to replacing and rebuilding. My local dealership told me I had two options. 1. replace the engine with a brand new one - 6-7k, or replace with a rebuilt one for 5-6k. F them is what I said. I hunted Mazda down and harassed them. Recorded conversations with executives and ended up winning in the end when I received a letter in the mail to be re-imbursed for my expenses. Don't get burned. Get rid of the car and then stop random people on the street and warn them about the CX-7 like I do!
