2007 Mazda CX-7 transmission complaints

Our 2007 cx-7 mazda developed noise. We received letter from dealership regarding possible need to fix AC compressor. About 10 days later on sept.5 2010 we took a trip and did not turn on the AC but a loud noise developed and we lost acceleration ability. No warning light ever came on. Our car has about 40,000 miles on it. Towed it to mazda dealershilp. They said they couldn't tell what was wrong. Several days later they said the turbo had failed and the engine is ruined and would need replacing. They said that the engine had no oil (remember, no warning light) and they found sludge, indicating neglect. We have had oil changes as required. They have not agreed to fix it. We have found numerous other owners of same model and year online on edmunds.com. It seems to be a problem for this particular model and year and the dealers response is to deny honoring warranty due to "sludge". Our next move is to take it to the dealership we purchased it from out of town.
I have a 2007 mazda cx-7. It is a very beautiful car but also has tons of problems. At 15000 miles it was leaking oil and they replace the engine gaskets. Then later was also leaking oil. Was told by the dealer that it was not. Took it to someone else who said it was leaking from the timing chain. Mazda resealed it. Since then my car doesn't shift properly going up and down hills. My air conditioner is hot and makes a funny sound. My car has loss of power and sound like a diesel. Overall I think that mazda needs to step up and take care of the problems or they will not get many returning customers! Something needs to be done! It was a 35000 dollar car!
My 2007 cx-7 had been making a noise for a couple of weeks so I had it checked out by two different places and was told by both that the timing chain is about to break. It has 66k miles which seems low to be having this kind of problem. I will be taking it to the mazda dealership but since I'm over the 60k my warranty has expired.
Mazda 2007 cx-7 engine seized. Heard a clicking sound for a few seconds at the start-up of the vehicle intermittently and would go away. This went on for a few weeks, but did not occur everytime the car started. Car seized at a traffic light and failed to operate normally, loud clanging noise followed by decrease in speed, could not get the vehicle past 15 MPH. Car has 30,000 miles, called dealer since vehicle is still under warranty. Dealer indicates that engine and turbo need to be replaced and has contacted mazda for warranty verification. No oil in car, and mechanic reports sludge in oil pan. Dealer requested receipts for all oil changes and parts since I performed all maintenance. I have no receipts. From reading the horror stories from similar individuals online with same problem, mazda will more than likely decline my warranty and claim that I the owner did not properly maintain the vehicle. I have had several past problems with my vehicle since its purchase and have had warranty service work performed on numerous occasions. With all the times that my vehicle was in service, I was not notified of a mazda service bulletin #01-002/08, which addresses certain VIN # 2007 cx-7's (mine qualifies) to have a variable valve timing replaced due to numerous engine failures coinciding with the problem that I have experienced. The bulletin indicates that only customers who complain of engine noise will be treated with warranty replacement service. Since I had no inclining of the ongoing issues with the 2007 cx-7, I am being penalized for having to pay for the engineering defects with the mazda 2007 cx-7.
Like tons of other reports online, my 2007 cx-7 is having a timing chain/vvt actuator failure at around 40000miles. Luckily, after reading the reports online, I told my mazda dealership about this problem and they are in the process of repairing while timing chain was at its breaking point (that would have resulted in a blown up engine while driving).
2007 mazda cx-7. 47,000 miles. Clean engine and clean oil per the service desk at the mazda dealership. Pin related to timing chain broke, which caused the timing chain to break and ruined the entire engine. My car died in the middle of a very busy road and another vehicle almost collided with me as I slowly tried to move it over to the side of the road before it stopped altogether. While the company has yet to decide if they will pay for the repair since the car is under warranty, I still believe this problem should be investigated as a recall issue because of the amount of complaints I have seen online about other mazda cx-7 owners have this same issue.
Tl* the contact owns a 2007 mazda cx7. The contact stated the CVT transmission and spring tensioner failed. The contact stated the parts were manufacturer from plastic and believed it to be the cause of the failure. As a result, the timing chain would continuously fail. The vehicle was repaired by the dealer. The failure continued to recur. There was not a recall for the failure and the vehicle was not further repaired. The manufacturer did not provide any assistance. The failure mileage was 45,000 and current mileage was 78,000
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!
My wife and I purchased a 2007 mazda cx-7 a few years ago, and over the last three months it has been in the shop with multiple problems. From an oil leak, to a bad compressor, then the timing chain gone bad and now another problem with the egr. The car has a little over 38k miles and to me it seems very odd for a car being this young in miles, to have major problems such as these. After going back and forth with the mazda corporate office, they first agreed to pay for the parts for my latest problems since I'm now out of warranty. I was fine with that until I found out the labor was over $500 to fix this problem. When I call the corporate office to try to discuss splitting the labor costs, their supervisor contacted me back with an attitude like I did something wrong and decided they were now not going to help at all. That is just poor customer service behind a vehicle that was not ready to be put on our us roadways. In my opinion, this car should be recalled. After reviewing some of the forums, many others agree with my displeasure in the problems with the mazda cx-7--check this linkhttp://townhall-talk.edmunds.com/direct/view/.f0e5b59/110. Thank you.
Vehicle driving on route 95 south at 60-65 MPH lost power immediately for some unknown reason. Driver able to get car to breakdown lane without power. Unable to start vehicle. Vehicle towed 100 miles to service station. Determination timing chain broke at 72,000 miles. Dealer replace timing chain. Unsuccessful. Needs a new engine. New engine ordered. Parts are at dealership. Potential for injury or death was very great due to rate of speed traveling on a major interstate and sudden loss of power of the vehicle. Breakage occurred at night also.
After short duration idol "5-10" minutes car blew heavy white and black smoke out of exhaust followed with a clanking/rattling sound from the rear of car. Three time this happened in a short 4-7 mile drive home. Took it to the dealer and at first the said they could not duplicate the problem but updated the engine and transmission computer program. Then they let the car idol for some time and it blew the smoke and heard the sound. So they decided after calling and reporting the event to the regional manager to replace the turbo. I have looked on-line about these problems and have come across owners that have had their turbos replaced a few times and the problem still exists. When the parts are in and they replace the turbo, I will see if this is a fix. I have very little faith that this will fix the problems this vehicle has. And it has many.
Dt*: the contact stated upon acceleration, the vehicle hesitated. It was driven to the dealer who determined the control module computer in the power train needed to be reprogrammed. The vehicle was a 2007 mazda cx-7. *ak updated 10/31/2006 - right front window failed. The dealer replaced the left front switch.
