Engine Problems of Mazda CX-7

My 2007 Mazda Cx-7 broke down without warning. Found out the timing chain had snapped as a result of a piston blowing. I have been told the turbo seized and caused excess pressure causing the piston to blow and breaking the timing chain. Have found many people online complaining of same thing happening to their Cx-7.

End of summer service, I complained about a smell coming from the engine like burned breaks the technician told me it was nothing major and that they will monitor it on the next service call. I took it for service on mid December and they serviced the transmission, oil change and no mention of major problems. On December 31st on my way to silverthorne from denver the engine stopped running on a steep hill shutting down power steering and breaks, I was able to stop the car and tow the car back to denver, I was just informed that my three year old car needs a new engine worth $7,200 vvt actuator and timing chain were shot and the engine is dead. I took this car to the dealership for service regularly and nothing was mentioned. I have done research and there are hundreds of people with the same problem, please what can you do? I only have 93k miles and the car is three years old.

I have a 2007 Mazda cx 7. I bought it new in February of 2007, so the car is only 3 â½ years old. Two major things have happened to my car within the past two months one of which seriously put my safety in jeopardy. I will start with, two months ago, my air conditioner went out completely. The air compressor had to be replaced. Then, about a week ago as I was driving down interstate 75 (going about 70 mph), the acceleration on my car completely went out. Luckily I was able to get over the 5 lanes of traffic and pull the car off to the side. After I turned my car off, it never cranked again after that. Long story short, I took my car into jim ellis Mazda in marietta, GA and they said there was internal damage to the engine and the engine would have to be replaced completely. They couldn?t even tell me what exactly went wrong or really diagnose the problem for me. They just said the engine needed to be replaced. The kicker to this story is, when I went in a couple months ago to get my air fixed, I asked them to take a look at the engine because I thought it sounded loud. The said it was completely fine and nothing was wrong with it. Well two months later this happened. I have talked to Mazda customer service and they will offer no assistance for fixing my car (which I have been quoted $8,000 to fix!). I was told that Mazda had reviewed my case and I was declined because there was sludge around the engine, which apparently gives then reason for no assistance. They said that is proof that my car is not maintenanced on a regular basis, however I have documented proof that it is maintenanced regularly. They just didn't seem to care.

For quite awhile I had been hearing a "ticking" noise with my 2007 Mazda Cx-7. . Brought it to the dealership in lafayette, la. To have it checked out. They checked it out, updated recalls in affect, stated they found nothing. Continued to hear it off and on, had my oil changed regularly. On July 10, 2010 my car broke down (4 yrs old, 33,000 miles) had it towed to dealer in beaumont, close to where it had broken down. The service dept. Asked for my service records after it was determined that problem was with the engine. . Did not have every receipt due to dealer in area closing with no records there, but provide the last few. . After taking an "image" and sending it to Mazda, it was determined they would not honor the warranty because I had excessive "sludge" and wanted me to pay full cost of a new engine/motor. No one wanted to listen to me. . I do remember that when my oil was changed, the mechanic had told me in the past that it seemed to have "sludge", but that was only between 3,000 miles. I had taken care of my car, and they were telling that it had "poor maintenance" and would not honor the warranty!.

I own a 2007 Mazda Cx-7 while driving down the road a 60 mph the motor shut down and lost all power. The car has 52,000 miles on it, and is still under manufactures warranty. I took it to a local Mazda dealer to have it fixed. After 2 weeks of waiting they informed me that Mazda corp would not cover it under warranty due to engine sludge. The oil has been changed at intervals of 3000 to 3500 miles. Why will they not address this problem if so many other people have had the same issue with this year, make, and model? this is a serious safety issue and could cause an accident or fire.

Tl- the contact owns a 2007 Mazda Cx-7. The contact stated after the vehicle was parked and he restarted it the vehicle would not start. The vehicle was taken to the dealer three times and after a diagnostic test the dealer could not diagnose the failure. The manufacturer was notified and offered no assistance. The failure mileage was 26,000. Rvk.

Without warning of any kind this car simply stopped and would never start again. We are currently repairing this vehicle. Oil chain failure which caused timing chain to jump the gearing, repairing the valves subsequently.

From 4/14/10 thru 4/22/10 my well maintained Mazda Cx-7 with 19,767 miles was serviced at rohrich Mazda in pittsburgh, PA for a timing chain repair. On 5/11/10 with 20,000 on the vehicle, while driving to a local supermarket, my wife began to smell gasoline. After 1-2 miles of driving with this smell, there was a loud "pop" and the engine was on fire with flames shooting out from beneath the vehicle. The vehicle was completely destroyed. Erie insurance assigned a special investigator who determined the fire's cause to be "undetermined" due to the extensive physical damage to the components. However, his opinion was there was improper reassembly with the recent repair. Rohrich Mazda denies any responsibility claiming it had nothing to do with the repair & recommended we follow up with Mazda directly. Two other vehicles were also damaged in the process. Fortunately no other injuries occurred. This should have never happened to this car with only 20,000 miles on it!.

Timing chain broke and damaged engine Mazda Cx-7 - 2007.

2007 grand touring Mazda Cx-7 had bad ac compressor as typical with model at 30k miles and was putting out black when car returned in a "fixed" condition. They sited that we had "dirty oil". Timing chain went taking engine at 42k miles and we were first denied warranty work due to sludgie engine with Mazda stating it was our lack of maintenance. After filing for bbb arbitration the agreed to replace engine and turbo if we paid the $900 labor bill. Car came back after a month with a rattle and putting out white smoke. Rattle I was told on phone at first was not repeatable then when adressed face to face was a loose engine bracket but went on paperwork as stabilizer bars front and rear. Engine with 2400 miles on it is still putting out white smoke and acting sluggish and transmission shifts hard and likes gears 2 and 4 for the most part. First was told they could not see smoke then when addressed face to face was told cause it was cold outside then second excuse was condensation. . Was told by mechanic friend he thinks turbo is going bad after a whopping 2400 miles. Spouse wont let me operate car any longer in fear it will break down causing accident. As far as their service bulletin states that they dont have the turbo valve fix yet. . How am I to think I received a "fixed" car if I got a rebuilt engine a new but same brand etc turbo. . . Not safe and sad to think someone will have to die before this is addressed.
