Engine Burning Oil Problems of Mazda CX-7

There was blue smoke in 2013 and the engine oil had been burned to nearly empty. It was fixed with my own pocket but in happen again. Fyi, the first time it happened at almost 40,000 miles and right now is 62000miles. Right now there is a problem of the power steering pump which may out of control when it makes turn. I read anticle say that Mazda will recall cx 7 including year 2008. When I call them today they said no such kind of recall. I read a lots of article complaining Mazda Cx-7 regarding of these two issue. Hope your department can follow up to protect consumer. Also when the car runs in highway of fast enough there's no smoke but when it runs slow the smoke come out tremendously. Thanks.

I have white smoke coming out of my tailpipe when it idles. I also have a burning oil smell in my car. I have to roll down the windows when I get into my car. I have a 2 1/2 year old and I cant imagine its safe for her to breath this in. I took it to green Mazda in springfield IL to be repaired, this is a known issue with this vehicle. They installed a ventilation kit. That did not solve the problem. I took it back and now they say there is no problem. So they saw a problem and installed a ventilation kit but now that is doing the same thing there is not a problem. The next step is to replace the turbo, which they will not do. This should be a safety recall.

June 2014, I was driving vehicle out of town on vacation and it suddenly began running rough like the pistons were misfiring. Mileage was 69,700. I pulled into a dealership (1 mile away), dropped the keys, and called to explain in the morning. Later, they said they drove the car around the lot and the engine locked up. They took no responsibility for making it worse and charged me for confirming the loss of compression in the pistons. We replaced the engine at great expense and to a poor result. I found this 2007 model had a chronic problem with the variable valve timing (vvt) causing the timing chain to come out of adjustment and destroy the engine. Instead of issuing a recall and fixing it, Mazda offered an extended warranty to 6 years-60,000 miles. This is about the average point of failure, meaning half the people are not covered. A feature of the turbo charger is making the engine run hot, burning the oil, so people were often denied because the oil "had not been changed. " interestingly, Mazda said the timing chain had been replaced under warranty with a previous owner. That date and location coincided with a date of service shown on carfax for typical maintenance only. That dealership said they could not possibly do any work without it showing on carfax. I wonder who Mazda paid for the warranty claim. . . I want NHTSA to compel Mazda to compensate owners who experienced engine failure due to this documented design flaw.

Sudden loss of power as the turbo stopped working. The Mazda dealership claimed that the turbo broke due to sludge in the engine. There was a lot of sludge in the engine, however, the car was well maintained with regular oil changes. It seems that the median engine temperature is hotter than is appropriate for the specified oil in the owners manual. This results in oil burning and sticking to the inside of the engine. Eventually a piece of "sludge" will come loose and clog the oil tube to the turbo, resulting in the turbo unit overheating and breaking. Mazda seems to be aware of this problem as they were pressured to extend the warranty on this part. However, the problem is very serious and there should be a recall of the turbo unit and clarification in the owner's manual. Mazda has yet to agree to fix the turbo and "sludge" in my engine. They are still insisting that I did not maintain the vehicle well. Fyi- I was a car designer with Honda/Acura for 4 years who designed the 2009 - 2012 mdx. I am stating this because I know SUV's and how to maintain them very well.

I was experiencing a shake in the steering wheel at high speeds, which we attributed to a tire/wheel/alignment issue. I made an appointment when the check engine light came on. The dealership told me I needed the timing chain (and assorted peripherals) replaced. . . For the second time in two years. The first time was covered by warranty, but only after I produced the records to show the oil had been changed regularly. The second time was not covered under warranty. It cost $1500 to replace the entire assembly that was less than two years old. The dealership has recommended ignoring the manual on oil changes (every 7500 miles) and changing it every 3000 to hopefully catch any further issues. They said because the turbo runs very hot, it burns up the oil quickly. My car was very low when I took it in. They also said the check engine light will not go on due to low oil, but only for low oil pressure. The other issue I had was related to the rear view mirror. I have the auto-dim with compass, which was installed by the dealer when I bought the car. It has failed twice and been replaced under warranty. The second time was around 65k miles. Less than a month after my warranty ran out, the entire mirror fell off the windshield. In the early 2007 models, the clip that holds the mirror can not be replaced if it breaks. I had to have the entire windshield replaced in order to re-attach the mirror. I was told even though the mirror would have been covered since it had just been replaced, the windshield was not covered. That was another $250 to replace a perfectly good windshield just because the clip couldn't be fixed. I have seriously considered just trading this car in because I doubt very much it will be worth more than scrap value in a few more years.

On October 4 2012 I was told by the Mazda dealer service dept that my timing chain and turbo charger on my 2010 Mazda cx7 went bad and needed to be replaced. My vehicle only has 39400 miles on it and should be covered under Mazdas power train warranty. I was told by Mazda warranty department that they would not pay for anything based on sludge build up in the engine. I sent them copies of oil change maintenace as they requested which were done at aprox every 3400 miles as apposed to the required 7500miles. I was told then that they would cover only the timing chain replacement because it was on a recall and that the turbo charger would not be covered at all. They came to this conclusion due to the turbo going bad due to an outside influence what is that I asked and they had no answer. The answer I was givenm is it will not be covered under warranty and that is that and I have basically no recourse. There is clearly a problem with these cx7 as there are so many similar complaints all over the internet and yet Mazda refuses to pay on these part that should be covered under the powertrain warranty 6yrs/60,000 miles. The car gets too hot and burns the oil and that is what causes the sludge a manufactures defect not negelcet on oil change and filter maintenance. Other Mazda owner have the same result wether they oil changed at 3000, 4000, or the required 7500 how can we all have sludge in the engine. Obviously there is a manufaturers defect regarding this entire turbo system. Mazda needs to own up to the defects regarding the cx7 models and honor the customers warrenty work. The car has so many problems that they are presently not making it anymore. I do not have the money to layout and wait to be rembursed possibly by Mazda in the future this is a disgrace. I will never drive another Mazda vehicle again and I will not ever reccomend them to any one.

In January 2012, I received a letter from Mazda inc that the company was extending the warranty on the timing chain to 70,000 miles. In the letter, it stated that a certified Mazda dealer could inspect the vehicle to determine if the timing chain has a problem. On Feb 24 the vehicle was inspected by a certified Mazda garage and when my husband went to pick it up, they said "it has a slight noise but nothing big. Then they asked for all the receipts from the oil changes. Now, we bought the car in March 2009, therefore we would have no receipts for the past year and a half the car was with another owner. We only had 3 receipts b/c my husband routinely change the oil . Now, the other thing was in early February, the vehicle began to not start all the time. It was taken to our local garage and the repair man said it could be a number of things, but since it has the timing chain issue. . . That could be one of the problems that causes a car not to start. It left me stranded on 3 occasions. So,from February until March 30, my husband argued with Mazda and the dealership that first inspected the vehicle. The deal was Mazda was not going to pay for a new timing chain b/c we couldn't produce oil change receipts and if there was sludge in the motor "this could be why". So on March 30, the Mazda dealership called and said for $180 the gaskets could be pulled to see if there was sludge. Which in all the reports that I read on this website, majority of engines had sludge b/c the motor burns the oil too hot. The other repairs that vehicle had: 2010 -air conditioner compressor (it was recalled) ($900), a new starter ($300), Dec 2011- rt rear wheel bearing ($600), Feb '12- new battery ($100) which didn't need to be replaced b/c it was part of the timing chain problem. So on April 4, we traded the vehicle and bought a 2009 Honda cr-v. My husband and I will never by a Mazda again.

2007 grand touring Mazda Cx-7 has well known vvt issue causing oil to burn, in spite of regular oil changes and all recommended maintenance. We are original owners and know how car was maintained . Timing chain went at 62k miles, just out of warranty. After that service, drove 1k more miles and noticed loss of acceleration. Took car back to dealer, and they advised we needed a whole new engine, which they would not cover, aside from a 20% goodwill offset. Spouse wont let me operate car any longer in fear it will break down causing accident. Unsafe vehicle.

Mazda cx7- turbo engine failure. Excessive oil consumption and burning oil lead to turbo failure and ceased engine. June 30, 2010. Had to pay $10,000 to replace engine and other major parts in SUV. Mazda blamed customer although there are 100's of complaints regarding this very issue whereas the customer was ultimately blamed. It is well documented about the excessive engine oil consumption and engine ceasing on these vehicle. Each complaint has the same problems and end results. Customer is blamed for lack of oil changes and therefore blamed on the failure of this vehicle. I eventually had all of my oil change certificates and was told by Mazda they do not honor hand written receipts. Mazda only wanted computerized receipts. All of my maintenance was done by mechanics that have a combined 50 years in business . That was not good enough for them. There fore I had to pay this huge bill to get my vehicle back.
