Mazda CX-7 Engine Problems

    You've done everything I would do except for one thing.

    Here in Boston, some of the local ABC, CBS and NBC news affiliates have a consumer advocate that reports on scams or bad business. These spots are run during the evening news. Ild call them and have them show up a the Mazda dealership or perhaps they can call Mazda USA and see what response they get now.

    I'm truly hoping these problems have been resolved in the 2009 model.
  • Here is a GREAT idea if you do not get the resolution you desire in this situation. Go and park your car outside the dealers entrance on weekends and tie a bag of lemons from every door handle on the car. In addition write a BIG sign that says Mazda sold me a lemon and wont fix it. I guarantee this will capture the attention of the service manager to resolve the issue. In the meantime drive all around town with the lemons hanging from your door handles. No making lemonade here, this is just sour business practices that need to be stopped.
  • My 07' Mazda CX-7 just had the same problem on the 13th, and guess what the dealership said the same thing due to improper maintanence which isn't the case at all, why should I have to go back and search 2 years worth of records for them to tell me tough luck, I am seriously looking into a class action lawsuit, has anyone looked into this already?
  • I do not think anyone has looked into a class action suit. When I put my problem out there with the engine and then the turbine I did not know how many cars had a problem. I have all my records for oil changes and work at the dealer ship. They just did not want to see them.
  • I Just replaced my engine at 42000 miles with no help from mazda. Has anyone had luck gettintg through to them or hearing back? They used the same "lack of maint." deal with me, even though I bought it used and only owned it for 8 months. I had to pay another mechanic to replace the engine. I don't have money for lawyer . . .any suggestions?

    Yes, in the future stay well away from turbo charged engine, ESPECIALLY second hand.

    The words "TURBO" and "TurboCharged" are a well known attractant for those of the "boy-racer" mentality, if not actual "boy-racers". They do not treat their cars/engines well and probably remove all of the aftermarket GU-GA, evidence, prior to resale.

    Mazda knows there is a problem with engine sludge. Mazda has allerted their dealer network as well. I'm just curious as to what they are going to do about it.
  • Add me to the list. My CX-7 has failed and dealer wants $90 per hour just to diagnose problem. After only about 30-45 minutes of research, I have come to believe that consumers may have grounds for a class action lawsuit against mazda. This vehicle is horrible.
  • BTW, this is a 2007 with about 70k miles on it.
  • I am the original "poster" of this message.....still have my 07 Mazda....still having problem after problem with the darn thing! I would be very happy to be added to the class action lawsuit list when it comes available.

    Good luck to all.....I know I have learned not to ever buy another Mazda!!!

    Happy Holidays!
  • The grinding at startup noise is a simple VVT actuator problem.. your dealerships must be extremely clueless.
  • +1 more for timing chain issues.... 57,600+/- miles

    I don't have the details yet - except for the '07 CX-7 started losing power and making strange noises. Luckily, we were only 3 miles from a Mazda dealer. Initial diagnosis was timing chain related (probably broken tensioner/idler since the engine was still able to run). Today, I received the call nobody wants to hear: "can you provide proof of oil changes". Ummm... no, I did almost all of them myself.
    I think I'm gonna be sick...
  • My timing also went out said i needed new engine warranty out 75000k not true took it somewhere else timing out. mazda conroe tx refused and also lies about what is wrong found this online to day 1/29/2010

    BULLETIN NOTE

    When the engine is first started, some vehicles may exhibit a loud ticking noise from the variable valve timing
    (VVT). This is caused by the lock pin of the variable valve timing actuator not fully engaging. Heat treatment has
    now been added around the hole of the variable valve timing rotor lock pin to prevent this from happening.
    Customers having this concern should have their vehicle repaired using the following repair procedure.

    Hello,

    How did your hearing go? I am going the same thing right now and was curious.

    Thanks, DJ119
  • SAME THING HERE! My mazda was taken in and they are claiming "sludge is the culprit, and wont fix is due to "lack of mantienacne. It only has 44,270 miles on it, THis is an outrage! MAZDA is scamming its comsumers. The 2007 model is a crap SUV and they need to own up to it! If anyone is interested on a class action lawsuit please contact me. This all happpend to me last week, and I am not finding out how they screw over so many other people. Just today they told me they would buy it from me for 3000, i laughed at them, and said so you can put a new engine it for nothing and sell it for 17,000! they are insane, and taking advantage of people, and I wont stand for it! They told me they could fix it for $10,000 i laughed again!!!
  • My Car is fixed and DID NOT TAKE IT TO THE DEALERSHIP I took it to a well known mechanic you just need to find one that has the right machine to fix the Mazda C-X, timing chain broke, cracked the head gasket, bent 4 values and so on. Mazda dealership said I need a rebuilt engine for $7,500. because the motor is gone, well my car has been repaired and ready for pick up today Thursday 2.25/2010 total due $3,027.00, ($1,340.00 labor) but engine WAS NOT GONE NOR WAS IT FROZEN LIKE THEY SAID.

    BEWARE OF THE DEALERSHIP TAKE IT TO SOMEONE RESPONSIBLE AND YOU KNOW HAS GOOD REVIEWS ON THE REPAIR SHOP... THEY WILL FIX IT WITHOUT TRY TO MAKE YOU BUY A REBUILT ENGINE

    ASK THEM IF THEY HAVE THE RIGHT MACHINE TO FIX IT AND LET THEM KNOW THAT IT IS AN INTERFACE ENGINE..THEY WILL KNOW WHAT THAT MEANS.. GOOD LUCK

    I AM SO READY TO PICK THE CAR UP. I WILL MAKE SURE ALL MY OIL CHANGES ARE DONE AT THE SHOP THAT JUST FIXED MY CAR AND NOT THE MAZDA DEALERSHIP..THE ARE FULL OF HORSECRAP. :) :shades:

    SINCERELY,

    CHRISTINA TEXAS

    (st,d)ealer's cannot afford to retain mechanics with enough expertise to tear an engine down and rebuild it and still pay their kids tuition at Harvard. Plus the profits from charging $7500 for a simple engine swap are a bit to hard to pass up when the opportunity arises.
  • I wrote back in September, where they wanted to replace the engine for 7,000 and they then settled for 6,500. After that was done 3 weeks later the turbine went and they wanted another 3,000. I got 8,000 for it.
  • i have a useless 07 cx7 with 39000 miles and a blown turbo mazda states there is sludge in engine and points to customers lack of maintenance not true have all my reciepts and sent them like they asked.they still will not warrant the turbo and say i have to pay around $9000 for a new engine and turbo.dealership in san antonio named ipac mazda owned by larry benson told me when i bought my vehicle new with 1600 miles that the 36000 mile bumper to bumper would extend to 37600 miles since i was the first owner not true according to mazda usa .nothing but head aches from this vehicle stay away from mazda and ipac mazda in san antonio,tx
