While driving home with my A/C on, my 2007 mazda cx7 began making a terrible whining & grinding sound, followed by billows of smoke coming from under the hood. I immediately pulled off the road, turned off the car and opened the hood, which continued to smoke for some time and there was a smell of burning rubber. I burned my hand in the process. The car was deemed unsafe and undriveable and had to be towed back to the nearest mazda dealer where we had also purchased the vehicle. It was late at night, so ,the next morning I received a call from the dealer telling me the fire started with the A/C compressor, which then ignited the drive belt. That's why it smelled so awful. He said it was "burned badly". The parts were not in stock, so, they have to order new parts. So, I'm without transportation. No offer from the dealer for a rental. They also did not tell me that there was a recall on 2007 mazda cx7 A/C compressors, which I learned about by online research. I never received a letter from mazda regarding the recall. So, it turns out that many, many people are experiencing the same issue and not enough is being done about it to fix the problem. The car has less than 30k miles and recently had a full inspection by the dealer. I'm now waiting to find out if the dealer will try to get me to pay for this or if they will honor the warranty. Many online complainants are being denied and are being forced to pay for this themselves. This is not right.

In april 2009 the air conditioner compressor failed on my 2007 mazda cx-7. There was approximately 49,000 miles on the car when this happened. We replaced the compressor with an aftermarket compressor because the dealer indicated it was not in warranty. Some time later we received a letter from mazda extending the warranty on the compressor to 60,000 miles. In the letter mazda explained that if the compressor had already been changed they would reimburse us for the charges. The paperwork had been misplaced at the time so we did not contact mazda for reimbursement. In december 2010 my daughter was driving the car in dallas texas when she heard a noise coming from under the hood. A burning smell started coming through the vents, then smoke started coming into the car, she had to cross three lanes of traffic to get off of the road. The car stopped running before she could get off of the road. A driver stopped and helped her get the car off of the road, luckily no one was injured. She called me and told me what happened, I called for a wrecker and had the car towed to a mazda dealership nearby. The service manager called me and told me it would cost approximately $ 1,800.00 to repair the car. He also told me that the mileage had exceeded its limits for warranty. He later called and said that when the belt broke it had damaged the pulley on the crankshaft and that for the car to run properly it would also need to be replaced. I contacted the consumer division of mazda and was basically told there was nothing they could do, they extended the warranty to 60,000 miles and that the car had exceeded its warranty. It is not normal for AC compressors to fail in such a short time unless there is a defect. Mazda knew this that is why they extended the warranty. Mazda needs to recall these defective compressors before someone is severely injured or killed in a wreck caused by the compressor locking up.
Turbo engine failure. Major problem #3 -2007 cx-7 1. A/c conderson frozen - cost $1,225.00 2. Timing chain broke-cracked gasket,bent valude, etc $3,025.00 3. Turbo engine failure unknown at the mazda dealer ship.
2007 grand touring mazda cx-7 had bad A/C 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 sludge 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 addressed 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 don't 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.
An excess of white smoke emitted from exhaust upon acceleration after a brief period of idle. It was determined that a faulty turbo charger was to blame. So the car was in the shop for 7 days while they replaced the turbo. Several months later the car wouldn't start after sitting in a heated garage overnight. It sounded as though the cylinders weren't firing properly. Car was towed to mechanic who identified issue as fouled cylinder heads from prior failure of turbo. This time the entire engine was replaced. Again the car was in the shop for approximately seven days. Some months later an oppressive amount of road noise appeared at all speeds on all road surfaces. We were directed that the tires were to blame. After replacing all 4 tires at a cost of nearly $800 the sound persisted. Upon further inspection the technician found that the wheel speed sensors on the rear wheels had failed allowing water to seep in and rust rear wheel bearings. All four wheel bearings where replaced. Today the vehicle is again in for engine repair to replace the oxygen sensor and a dead battery. After owning the car for 18 months it is has been in the shop for a total of approximately 4 weeks.
Complete engine failure without warning while traveling 70 m.p.h down 40 east xmas eve evening. I prayed my child and I wouldn't end up dead while trying to cut across two lanes to get off the road in my vehicle without engine power.
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.
2007 mazda cx-7 - A/C compressor went out (mileage 43,090 and out of warranty) on way to work on 1/4/11 around 7:30am. My car started making loud noises from the engine the day before but their were no warning signs in my car. On my way to work a lot of white smoke from my tale pipes started coming out and the noise got louder along with a burning smell and then my battery light came on and my car cut off while I was on the highway. I was lucky to coast off to the side of the road. $1250 to replace parts/tow and labor. Seems this is a known issue with mazda because I have been on a lot of forums where tons of people are having the same issue. Mazda on rt. 42 south jersey nj didn't mention this was a known issue. Many customers have had this happen multiple times. Some within the 36k btb warranty, some after. With this being a known issue, shouldn't this be a recall if it is a problem that will occur on most 2007 cx-7's with the part?
My wife's 2007 cx7 was in a parking lot. My wife started it up, came to a stop sign and the car died without warning. It had 65,000 miles on it (5000 over the warranty) and wasn't even 3 years old. We had always gotten regular oil changes and had just had one the week before. We had it towed to the nearest mazda dealer. The first time I talked to a service tech he mentioned the timing chain breaking. Later, they explained it as a valve (variable valve timing actuator?) failing and causing oil chain failure (jumping the gearing). My bill ($7500 - new engine) only states internal parts failure. They tried to indicate the oil was dirty even thought the oil was changed less than a week prior. After reading through many cx7 forums online it seems they were trying to build a case for engine sludge to cover themselves. Less than 2 months later replaced intake manifold shutter valve and had to flush and reseal brake lines. Went to kerry mazda of ky to originally purchase a 2008 because of low finance deals. They shifted my attention to the 2007 (3500 miles) and I agreed because of the certified new (100,000 miles) program. When I found out I didn't have 100,000 mile coverage I went back to dealer and we pulled the paperwork and under the warranty it says certified and also remainder manufacturer's warranty. So it ends up they sold me a used car as new and I didn't even get the financing of a new car - very shady. Mazda corporate was of no help either, simply stating the car was out of warranty and there was nothing they could do. Needless to say I will never buy mazda again. I will also make sure I don't trust what they say and make sure I read and understand every page even as they try and rush you through it. I fear someone will be killed when their cx7 suddenly stops on a busy highway. Hopefully, mazda will address the problem before that happens.
I have my 2007 mazda for a year and it has been at the dealership for 1/2 the time I've owned it . It is the worst vehicle that mazda could have made it needs to be recalled because of numerous problem someone is going to lose there life. I have had so many things done to my vehicle actuator 2 oil on the engine, turbo went out, timing belt , tie rod broke and tire came off and hit a truck, air conditioning went out , the list can go on and on just got it back after being repaired and it has to go back to the shop on friday this is the worst car in the world it is a lemon mazda should be shame of themselves for selling this piece of crap.
2007 mazda cx-7. Consumer experienced several problems with vehicle *tgw the consumer stated shortly after she purchased the vehicle, she noticed the headlights pointing toward the ground and it took 3-5 trips to the dealer before it was properly fixed. In june 2010, the check engine light illuminated. The dealer diagnosed the problem as an evap system leak which cost $461.80. In october 2010, during a routine inspection, it was discovered that the vehicle needed an outer tie rod end, in addition to that an alignment was also needed. One week later, the AC compressor failed.
Timing belt broke at 80,000 miles requiring a new engine.
2007 mazda cx7, at 57,211 miles , air condition compressor froze, disabled car. On 10/27/10 88 k miles, car would not start, independent garage determined it needs a new engine.called mazda corp. File # 132495780. Mazda representative asked to tow the car to a mazda dealer for diagnostics, and mazda will send a field manager to determine if the engine failure is due to manufacturer defect or not. Mazda may be willing to offer after warranty assistance in the cost of the repair or even cover the entire cost. Car was towed to a mazda dealer on 10/28/10 am. At 5 pm same day, dealer called my wife and said that the car needs a new engine and it will cost $8000 + to fix it, and the mazda corp field manager said that based on the maintenance record and mileage, mazda corp will not offer any assistance. I was never asked to provide any maintenance records and I do not believe the field manager even looked at the car as mazda representative said he would. Thier is 195 complains filed with the odi in regard to 2007 cx7 compressor and/or engine failure. I believe that the air compressor and the engine failure are due to manufacturer defect. Mazda corp. Is very well aware of it , and not owning up to it. Mazda corp is not even honoring cars under warranty in most cases, using the excuse of lake of maintenance records and sludge in the engine. May be mazda corp. And the federal safety agency are waiting for some one to die before they investigate the problem with the engine and compressor on the 2007 cx 7.
I bought my 2007 mazda cx-7 on november 2, 2008 from tustin mazda. From day one I have experienced an intermittent metal knocking noise while accelerating. It sounds like 3 or 4 clicks and I experience a slight lose of power. I have taken the vehicle back to the dealer more than 4 times. Sometimes they have it for days; the last time for two weeks. The first few time they said they could not replicate the problem. About a month ago the dealer said they fixed it. They also said my oil was sludgy and suggested a oil flush. I did not op for the oil flush because my regular mechanic said they are over-rated and a few oil changes should clear it up and the oil the dealer used may be prone to slugging up. The noise returned almost the day I got the car back. I returned two to three weeks later and told the dealer service people the noise was back. They kept the vehicle for two weeks and charged me $252.00 to run tests. I was told I would not have to pay if the work was covered under warranty. They opened the engine up and said the engine was sludgy. They told me mazda of america would not cover the work and I might need major work. I am supposedly losing compression on two of the four cylinders. Because I cannot prove I changed my oil and do have receipts beyond the oil changes I had at the dealer, they say it is not covered under warranty. The vehicle only has 36,000. I think it had about 15,000 miles when I bought it when I bought it. The dealer is trying to tell me they fixed the problem I had been bringing it in for and the noise I hear now is new. It is not, it's the same! In fact I heard it again the day after I brought it home. I have done research on the web and it appears mazda uses the same excuse for a lot of similar issues and do not cover the work under warranty. They also refused to fix a recall issue I had in regards to a letter they sent me. They said I did not need the work even though the issues I have described are also described in the letter.
Tl*the contact owns a 2007 mazda cx7. The contact stated that the vehicle was taken to the dealer for another repair and also informed the dealer that it was making a noise. The dealer replaced the vvt actuator at that time. The vehicle was taken back to the dealer because the contact noticed that the failure continued. The dealer stated that the air conditioner compressor was the cause of the failure. After two days, while driving the contact noticed the noise again so the vehicle was taken back to the dealer; the dealer replaced the serpentine belt and pulley system. The failure continued, the noise worsened and the vehicle lost momentum while she was driving; the dealer then stated that she needed a new engine, new turbo, new pulley and vvt actuator. The vehicle had not been repaired. The contact called the manufacturer who asked that she submit maintenance records but offered no assistance. The current mileage was approximately 46,000. The failure mileage was approximately 40,000.
2007 mazda cx-7 begin making loud clicking noise in august 2010. Took vehicle to repair facility and was told the engine needed to be replaced soon, timing chain was loose, and two engine modules were giving faulty readings. Got a 2nd opinion from a mazda certified tech with same advice. Have all repair and maintenance regards to show that it was not a result of vehicle neglect. Vehicle has 79,000 miles on it and has been used for primarily highway travel. Also had an issue with compressor which I had to replace at my own cost.
I own a 2007 mazda cx7 and it was been at the dealer every month this summer and I'm on my second loner car. The trouble started last summer with pinging and turbo lag. That seemed to stop and the dealer said that it was a software issue. But this summer we have had three separate issues. 1. Transfer case leak. Fixed. 2. Engine stabilizer leak. Fixed. 3. Variable valve timing actuator vvta. Currently in shop. Car loudly "growls" to life, squeaky belt, difficulty starting, told by dealer that will eventually cause engine trouble if not fixed. This has all been since july!!! We are just shy of 30k and the warranty expires next month. I am very afraid that something else will go wrong and we will end up paying for it. Upon reading a few cx7 web sites and blogs, it has become clear that this vvta issue will lead to a timing belt failure and engine loss. I have a little less then 30,000 miles on this car and bought it new. Unfortunately this seems to be a relatively common occurrence in the 2007 model. Please issue a recall so that this defect can be addressed prior to engine failure and not at owners expense. Thank you!
The timing chain is messed up on my 2007 mazda cx-7 it only has 85k miles on it.
2007 mazda cx7, broken air compressor at 30000 miles which destroys serpentine belt and risks overheating engine, causing burning smell and eventually smoke. Problem is not unique to me and my vehicle having read the internet for numerous similar reports from others.
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.
Tl* the contact owns a 2007 mazda cx-7. While traveling 60 MPH the contact noticed that the check engine light had appeared on the dashboard, seconds later the contact noticed that the vehicle had suddenly shut off without warning. The vehicle was taken to the dealership where the contact had the engine replaced due to the timing chain breaking. There were no prior warnings. The current mileage was 61000 and the failure mileage was 58000.
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!
2007 mazda cx-7 timing chain issue that needs to be replaced for free. The warranty company is trying to not pay the claim. I was driving 20mph and my car died. It was towed to the dealership. They said this never happens. I have gotten all of the oil changed in my car when it needed to be and they are trying to say that I did something to the vehicle. I'm 42 years old and paid alot of money for this vehicle. I do know how to take care of it.
Timing chain broke and damaged engine mazda cx-7 - 2007.
While normal driving, the 2007 mazda cx-7 stopped running. It was towed to the local mazda dealership (san antonio, tx). Upon further investigation, the consumer was informed that a new engine was required due to excessive sludge build-up in the engine. Additionally, the consumer was told that this repair would not be covered by the warranty due to lack of required maintenance resulting in sludge build-up. The vehicle was maintained in accordance with the owners manual, but the consumer was told approx. $7000.00 for an engine replacement.
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.
Mazda cx-7 with less than 90,000 has engine light on due to bad variable actuator for the engine and bad oil control valve. I have had regular oil changes and maintenance. The cost of repair is $1700. Last year I spent $3000.00 due to air conditioner and other problems with the car with less than 60,000.
2007 mazda cx-7 had failure of the air conditioner compressor. Bearings freeze up in the compressor unit. This causes pulley to stop turning and putting pressure on the drive belt. This causes car to overheat and battery to lose charge because alternator and water pump are not spinning. They do not spin because the drive belt slips over them because air conditioner pulley has seized up. This happens around 34,000 miles and generally within months of the expiration of the 36 month warranty. Internet research shows that this is a known problem to mazda. Mazda refuses to cover repair under power train warranty as it is not an essential part - even though the car become undriveable.
Mazda cx7 2007 issue with the AC compressor/ condensor.
My mazda 2007 cx7 stalled on me and then died on the side of the road. I had it towed to the dealership and on monday they told me the oil was low and I needed a new engine. I maintain my car as required and there were no signals indicating my oil or anything else was not working properly. I bought this car brand new in 2007 and this is the first major incident I have ever had. The dealership did not give any other options but to buy a new engine for 6,400.00. I was told that my warranty expired at 60,000 miles.
