On the day of April 22, 2015, while driving my car(2007 Mazda Cx-7) off a freeway ramp, the car began to rattle as if it was being pushed by a wind. I smelled smoke coming from the inside compartment of the cabin area of the car. I attempted to apply the brakes but the car won't stop! flames was coming from the car and that's when the car finally stop. There was a car in front of me that I thought that I was going to almost cause a major accident on the off ramp of the freeway. The mechanic checked the engine and stated that the engine locked up which caused a low compression to the engine causing the vvt belt timing to damage the valves in the engine. I changed the oil in the vehicle, and have the vehicle served on a regular basis, but never had any problems like that. I did research on this vehicle and found out that this is an ongoing problem with other owners of this vehicle across the country. There needs to be a investigation, reimbursement, retribution, and recall orders dispersed out to owners of the Cx-7 model from 2007 to 2012 so that Mazda can redeem their quality of service and reputation.

On January while driving home from a shopping trip my husband and I heard a really loud noise. In a matter of seconds my vehicle slowed down and almost caused an accident. I had it towed and calked the dealer I purchased it from after being told by a family mechanic that I should call because these was a faulty part with the cx7 vehicles. I called and didn't get any place with the dealer. Kept calling until finally about three weeks later they told me I should call Mazda directly and provided me with their number. I called Mazda and have been dealing with them ever since. They only want to pay $500 towards the repairs. This should be a recall since is faulty parts and there are hundreds of customers complaining of the same issues. The dealership that I purchased the car from told me there is also a problem with the vehicles timing belt, sounds familiar? yes!!! turbo and timing belt!! it is time for Mazda to take responsibily and not make us customers pay for faulty parts placed on a lemon of a vehicle. My email is dr880@verizon. Net. Please help me resolve this issue. I am so disappointed and frustrated and feel that Mazda is insulting my intelligence by offering to pay a miserable $500 towards a repair that they should do, since it is their faulty parts that lead to this car problems in the first place.

I was preparing to stop at a stop sign when my car stopped running. I had it towed to the garage who always maintains my car. They found that the timing belt had broken. I thought this was strange since my car only had 61000 miles on it, so I started researching the problem. I found that Mazda had put defective parts on these engines. They had an extended warranty, but of course that had run out for me. Why shouldn't a manufacturer have to stand behind the defective parts they put on an engine? this cost me $3700. 00 for their half-a* work!!!! if this timing chain had broken while I was in heavy traffic, this could have been a disaster!!.

After leaving a family member's out of state home early on Monday August 25, 2014 morning noticed a noise coming from the front of the vehicle. Approximately 5 miles later a burning smell and smoke started coming from the engine compartment along with loud squealing. Pulled onto shoulder of road and shut off vehicle. I opened the hood and it was obvious something had burned up but didn't easily identify what. Called aaa for a tow to nearest Mazda dealer. Was informed later in the day by the dealer that the ac compressor had seized up and ruined the serpentine belt as well. They didn't have the parts to fix it which resulted in having to rent a car for 5 days to return home and back to pick up vehicle on Saturday. Later found out there was an extended warranty on the compressor for 5 yrs/60k miles which meant that there was no coverage on my vehicle since it was 7 years old even though it had only 49k miles on it. Total cost with towing, the car rental and repair was $1667. They also "found" the starter was bad and a blown fusible link for which they charged another $648. I think they caused the started and fusible link damage trying to start the vehicle with the seized up ac compressor as I never had any problem with the starter before and didn't attempt to start it after I had pulled over and turned engine off.

Mazda extended the warranty on ac compressors, well, my original compressor failed and was replaced under that original warranty. Exactly 30,000 miles later the replacement compressor failed almost 3 years to the date of the original failure. Mazda is refusing any responsibility for this since now my car is out of warranty. Eventhough the replaced part itself is only 30,000 old. This vehicle is also experiencing timing belt issues and extrememly loud engine noise. This particular model year just seems to be a lemon all around. Even the replacement parts are failing. And the company is not holding themselves responsible at all. I've research this particular year and found more than adequate evidence that these vehicles are lemons. The same issues are being reported across the world! and Mazda is doing nothing. The hazards they are causing are tremendious! some failures have resulted in fires, quick loss of engine power at high speeds and thousands of dollars in repairs. My car was paid off less than a week before this second compressor malfunctioned. How many cars have had 2 ac compressors in a matter of 6-7 years?? and how many engines can completely fail in the matter of 7 years? everyday when I start my car it sounds like a deisel engine; popping and clanking noises project for the hood like it's a semi. That's just bad craftsmanship and bad business. Mazda should be held accountible. The recalls should be extended to 100,000 and 10 years at least. These vehicles should be built to last. And a multi billion dollar company should be made to fix their mistakes before someone gets hurt or worse, killed because of their neglect.

I was driving at about 25mph when I noticed a burning smell. I pulled over and popped the hood and saw smoke coming from the ac compressor. It turns out that this is common for this model. Mazda extended the warranty but of course mine expired this year. It's just a shame that my car has less then 40k miles and Mazda has acknowledged this is an inferior part, but wont help cover the cost. There are hundreds of reports of this part failing and breaking the serpentine belt causing the car to lose all power. This should absolutely be a recall. Imagine this happening while on a highway or turning at an intersection.

A friend of ours was driving to pick us up from the airport (our car hadn't been started for a couple of weeks) and, about 15 miles into the trip, the ac quit working. When he got to the airport, the car engine was smoking, there was a burning smell coming from the engine, and it sounded like a bearing was out of whack. We drove it home (approximately 45 miles), and the noise got louder and the engine started rattling louder and louder the closer we got to home. We took it to a Mazda dealership this morning, and they informed us that the ac compressor had seized and it, along with the belt (in addition to any other parts that may have been damaged) needed to be completely replaced and the refrigerant flushed/refilled. I did research and found out that this is a very common, known issue in 2007 Mazda Cx-7's with low mileage.

Air conditioning began blowing hot air. Many complaints logged online for this year vehicle having the same issue. Contacted the dealership to find the warranty has expired 3 weeks prior to this issue. Recommendation was to contact Mazda customer satisfaction. They provided a file number and informed I needed to have the dealership confirm the issue was the compressor. The dealership did confirm the compressor and belt need replaced. Contacted the customer satisfaction number back and the appeal/complain process began to see if they would provide financial assistance in replacing the compressor and belt since the warranty had just expired and only has 28,000 miles. Was informed 2 days later that the decision was that they would not provide any assistance since it is out of the warranty period. Very discouraged that a corporation would not stand behind they vehicle under these circumstances and the fact that they know this vehicle has these issues. I could understand if the vehicle had 60,000 miles but this is very disappointing.

Turning into a walmart parking lot my car shut down for no reason. Almost got hit by another car that was passing by since I was not able to turn. Turning into my apartment complex the car turned off again. Started to research issues with this car and I ran into many similar complaints. Car turned off another 4 times. Car shakes when I turn ac on. And when I place it on reverse. Also had the clicking noise but it seemed to go away. There seems to be some sensor issues. I took my cx7 to Mazda so that they can see what is going on. They ran tests. Came back and said it would cost me about $3500. It was a list of things that could be wrong they said, they were not so sure what to say. Mechanic then stated that since he works at Mazda he probably should not be telling me this but he said that he has seen that problem one too many times with this particular car. That yes Mazda does know about it but they blame the owners. So I asked it I were to pay this would I get some warranty, he said no because the same problem will happen again. God forbid that my car turns off and I have and accident, since car gives no warning. I have 2 children that ride with me all the time. Mazda had some sort of recall on this car a few years ago. I purchased this car February of 2012. I know understand why this person took car to trade out. Maybe they got notice but did not care to take care of it, they traded the car in. I think they should look at those issues on all Mazda cx7. Their main issues are the turbo, the ac, and the timing belt. If you read other complaints you will see that its the same issue which is due to the actual car not the owners, please help us affected by these vehicles get Mazda to finally take responsibility for this. Make them recall these cars and get the problem fixed. To where we wont run into the same issues over and over again before someone looses a life.

My check engine light came on as I was driving at 40 miles per hour. I did not notice a difference in the way the car was handling, however I took my car into my local Mazda dealer to have it checked. They informed me the cars timing belt needed to be replaced and there was sludge on the engine. Ironically I had just had my oil changed and my engine cleaned of sludge less than 2 weeks prior. We submitted the claim through my extended warranty and after a week got it approved. The morning I was slated to pick up the car I was told by the dealer that there was still an issue that they needed the car later. A few days later they told me I needed my engine replaced. The extended warranty denied the original claim now and the claim for a new engine due to poor upkeep, though I have my records of maintenance. I have only had the car for 1 and 1/2 years. This is ridiculous. I am now in the process of taking the car to another mechanic, bear in mind I have been without transportation for about a month and am pregnant. After researching this issue I have discovered tons of issues with the 2007 cx7 which can result in severe safety issues, engines losing power etc. Mazda is not owning up to any of it. No engine should die at 76,000 miles. This is deserving of a recall, Mazda needs to own their mistakes.

The air conditioning unit on my 2008 Mazda Cx-7 cracked, causing the pulley assembly to freeze up. As a result, the pulley no longer turned on the serpentine belt and made a loud noise, and the air conditioner failed to work. The car was immediately brought to the nearest Mazda dealer who diagnosed the problem and advised me not to drive the car, out of concern that damage to the belt might occur. In reviewing my files later, I found an August 2010 notice from Mazda advising me that the model year of my car might have this problem, and that the warranty coverage would be extended to 5 years or 60,000 miles. It further stated that no action should be taken unless I was experiencing an issue with this component of my car, which I wasn't at that time. Unfortunately, my problem did not emerge until now, and is not covered by this warranty extension since I now have 75000 miles on my car. However, air conditioner units normally do not fail on cars of this age and the notice from Mazda makes it clear that they are aware of this problem. I feel that Mazda should do the right thing and cover the cost of replacing the air conditioning unit in my car.

The contact owns a 2007 Mazda Cx-7. Months after the vehicle was purchased, the instrument cluster gauges flickered and the vehicle stalled. The vehicle was towed to the dealer. The mechanic replaced the timing chain belt and the engine assembly. The dealer provided no invoice of the repairs. Months later, the failure recurred. The vehicle was towed to an independent mechanic for further inspection and the contact was to tow the vehicle back to the dealer to determine what parts they actually replaced. The vehicle was not repaired. The manufacturer was notified of the failure. The approximate failure mileage was 34,366.

In November of 2012 my family was driving home from seattle, wa to san diego, CA. When we were driving we smelled burning rubber so pulled over to see if we could see something wrong under the hood. Since it was 10pm and dark outside we couldn't see anything and decided to find the nearest hotel to stay at until we could take it to a shop. After we started driving we saw there was a freeway exit 1/2 a mile away so my husband was driving really slow(about 35mph) hoping we could make it without any problems when all of a sudden there was a huge jerking motion that felt like we ran into something even though we didn't. We stopped immediately and got a tow truck. It ended up being the ac compressor and serpentine belt that needed replaced, although Mazda was aware of this problem as they stated in their extended warranty that it had "defect in workmanship or materials," the warranty was only extended to 5 years or 60,000 miles. My Mazda was 6 years old and had only 48,000 miles but wasn't covered because it was a year passed the warranty even though the miles were still under. We ended up paying $2,000. 00 to fix it as well as another $300. 00 to stay in a motel for 5 days. Ever since the day that the car broke and had the huge jerking movement, by back has hurt everyday since then. It especially didn't help that I was almost 5 months pregnant and although nothing happened to the baby, I'm hoping there was no permanent damage to my back since I've never had back pain or problems since before this incident. I didn't know who else to contact about this but I think this is a huge problem and Mazda needs to fix it before more people get hurt, especially because they already know this is a problem which is why the extended their warranty.

Ac failed on long trip. Temp gauge did not indicate overheating, no warning lights were lit up. After arriving at destination 5 hours from home, turned off engine and saw smoke coming from rt front hood area near wheel. Tried to start, not turning over. Added coolant to over flow (it was empty). Still not starting. No Mazda dealer open in area (closest one was 45 miles south in ft wayne. Time was approx 2pm on Saturday. Enterprise rent a car also not open except airport locations (they are open 8-12 on sats). Knew there was a w-mart nearby w/ auto service. Our vehicle is parked in large mcdonald's lot near the back out of the way, relatively safe location. . . Clld and spoke w/ [xxx] at wal-mart. He offered to come look at the car after work-w/in 15 min he was there. Because engine not turning over, he at first was concerned engine may have seized up/head gasket blew etc. He isolated the ac clutch as the problem by manually turning over the engine and then taking belt off completely. Started right up. . . He then proceeded to drive us to airport in ft wayne, had our car towed to his repair shop, accessed the problem area and advised me what part to order. The man is a saint. We spent 4 hours at airport until enterprise took mercy on us and rented us a car even though I only have a debit visa. Part has been ordered from dealer where we purch car. They matched price online of $289. 01 and shipping to indiana is only $12 will arrive by end of day tomorrow. Not sure what labor cost will be. Unable to order only clutch from Mazda. Don't need pump but will have extra in case it fails in the future. Information redacted pursuant to the freedom of information act (foia), 5 u. S. C. 552(b)(6).

I was driving on my way home on the highway and all of a sudden the ac was not cold. When we got home the belt was smoking from under the hood. We recently bought the car from a GMC dealership at just under 39k miles. Only owned the car for maybe 4 months. Turns out the car needed a whole new compressor for over $800. The compressor had locked up. I find this very crazy that a car with such little mileage would have such a big problem. The car has been well taken care of. Reading up online I have noticed the 2007 models have had ac compressor issues.

On may 18th I took my car to the Mazda dealer in NJ for a timing belt recall and was replaced. On may 28th driving on the highway the a/c stopped working, the warning lights came on and immediately the car stalled. I then had it towed to the same Mazda dealer. The next day they told me that my engine was blown and it was going to cost me $7,476. 79. I have always serviced my car every 3,000 miles, my car is only 6 years old and only has 57,040 miles. I took it to an engine expert and told me that the engine was defective. Mazda should recall all cx7s from 2007. It is obvious that all of them came out with a defect.

The air conditioning compressor on the vehicle seized with no warning & caused the serpentine belt to catch on fire. This appears to be a known issue with this vehicle, based on many postings on the internet. Additionally, the service manager at the dealer I take my vehicle to for service said a noise getting progressively louder in the engine is the timing chain adjuster that will require replacement very soon. He said this is a known issue with this particular vehicle, and the many postings on the internet about the same issue seem to confirm his statement. Combined, repairs for both will be in the $3500 to $5000 range.

There are two complaints for this vehicle. 1. Timing belt. . . Failure after 68,000 miles changed after a dispute with dealership, we still had to pay for 2 hrs of labor. 2. Turbo unit. . . Failure after 70,000 miles still at dealership. . . No option but to pay $3083 to get fixed. Turbo failure happened on highway, vehicle performed erratic and limped to off ramp using shoulder.

Car suddenly stalled 3 hours away from home; no noticeable performance issues / noise prior. Towed to mechanic who determined timing belt broke causing some valves to bend and other damage therefore replacement of engine required. Was on edmunds, other car blog sites along with researching this site and found that many, many others who have encountered the same issue around the 60k miles mark (or less in some cases). Spoke to Mazda and they are not taking any ownership or responsibility even though many incidences of the same mechanical problem. Oil changes were made regularly and car was last into Mazda for a noise less than a year ago which they said was due to my brakes. Have owned many cars before (not Mazdas) and this car is a huge disappointment as is my experience with Mazda. I hope this issue will be or is being pursued with Mazda.

2008 Mazda cx 7 grand touring - purchased pre-owned vehicle from a certified Mazda dealer in October 2008, had a loud engine sound and dealer advised this was "normal", just before warranty expiration found that transmission seal was bad and replaced this as well as the recalled compressor. Now at 64k and noise in engine is getting worse and it is in fact the timing chain lapping. Found out that this is a common problem and that some people have been having the chain break leaving them stranded in the middle of the road. Also found that the entire casing and the tensioning belt/mechanism is failing. This is a huge safety concern and I am surprised that no one has recalled this, it is a very common problem in the 07 model as well. Will request old parts be kept. Currently being worked on.

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!.
