2007 Mazda CX-7 engine complaints
Page 5 of 12: complaints 101 to 130 of 316, newest first, as owners wrote them.
On 7/11/12 my wife was driving on the entrance ramp to the fl. Turnpike when her mazda cx7, 07 engine turned off completely without warning. She was on a one lane road with a blind sided curve when this happened. A 18 wheeler truck was coming up behind her and almost rear ended her vehicle. Fortunately the driver of the truck was able to stop before hitting my wife car. After a investigation of the engine problem I found out that it was a bad timing chain that caused the vehicle to shut off the way it did. I called the mazda manufacture and they told me that they were aware of the timing chain problem and that's why they sent out letters for an extended warranty on the timing chain problem. The also stated that the only way they would replace the part is if I could show records of every oil change that was done on the car from the time of purchase. Being that I purchased the vehicle used I am not able to show all the oil change records they request. The point is that the manufacture recognized that there is a problem with the timing chain. They should be doing a immediate recall on the car to fix the problem before somebody gets seriously injured or killed..if you can I ask you to please help with this matter..
The vehicle suddenly stopped running while traveling at 65 MPH on interstate 95. The vehicle was safely moved to the side of the road where it was then towed to the dealer where it was purchased. The service representative indicated that the engine would have to be opened at a cost of $500 to determine the cause of the problem. They suspected that the timing chain had broken. After consulting with mazda customer service, I was advised to have the vehicle towed to a mazda dealer. The vehicle was towed to thompson mazda in baltimore, maryland where it was confirmed that the timing chain had broken and that the engine would have to be replaced. Mazda had provide an extended warranty on the timing chain for 7 years or 70,000 miles. The warranty indicated that if there was a timing chain noise to bring into a mazda dealer to have it serviced under the warranty. At no time was there a noise experienced from the engine. Mazda also indicated that the vehicle had to have service records to be covered. Since the vehicle was purchased used in april 2011 we only had our service records and the car fax service records. Mazda indicated that because there was a gap in the service records, between 31000 miles (the last record shown by car fax) and 54000 miles (when we had purchased the vehicle), they would not cover the cost of replacing the engine. It is my belief that mazda knew there was a defect in the timing chain and had they been proactive in recalling the vehicle and replacing the timing chain the engine would not have had to be replaced at a more significant cost of $7,200.
My 2007 cx-7 experienced a catastrophic failure of the A/C compressor resulting in smoke in the cabin. After parking to allow the car to clear it would not re-start and I had to be towed to the local dealer. This occurred late on a friday afternoon and so they were closed until the following monday. The potential failure was known and mazda had issued a letter extending the warranty on this item but not a full recall. The dealer installed new parts but since then it has been back several times because of lack of performance. I have received explanations of too much/too little refrigerant block dlines with particles from the original failure. After the third return visit in june 2012 the problem appeared to be fixed and the system worked until last week so I scheduled another visit. The problem has now being diagnosed as a failed hose fitting and they are expecting me to pay for the part but not the labor. My view is that parts like this should not fail at the current 41,000 miles and that some of this is related to the previous fixes. Also co-incidentally the check engine light came on as I was scheduling a dealer appointment. This has gone on and off several times over the last month. It has been diagnosed as a failed egr valve and will cost $700 to replace. Again this is not something that I would expect to need at such a low mileage and on a car that has all routine serving and has been babied. This prompted me to go on-line to research and there appears to be lots of similar issues with this model of mazda and yet they are not performing recalls. I am hoping that my experience will add to the case to pressurize mazda to be more customer orientated with their cx-7 owners and/or to support a class action suit to help recompense owners against these non routine mechanical failure issues.
Felt slight jolt, and immediately less power, then engine just stopped. My opinion is that the timing chain first "jumped" a tooth, then failed altogether. I was able to coast safely off to the shoulder, where I called for a tow. Car was flatbedded back to the dealer at my request, as they have done all work on the car since day 1. Dealer stated several days later that engine had no compression in two of the four cylinders, and a remanufactured engine would be required at a cost of $6400.00. Later, having researched this, it is a common problem and seriously premature for this mileage and for a car driven moderately and on which all recommended maintenance has been performed (by this dealer). I stated mazda should stand behind this and contribute all or part of the repair bill. Several days later, dealer states mazda refused.
My husband was driving the vehicle down a backroad highway going 60 when all of a sudden the car stopped. There was no notice, no noise nothing. The pos was towed to the local mazda dealership. The looked at the vehicle and said "timing chain..$3000". Ok, not what we expected but fine, fix it. 24 hours later, they called to advise that the engine is blown $7000. I contact the mazda customer service ( aka people who are trained to tell you that you are sol) to see if there was any recall or any other things that may cover this. No, nothing but a extension was mailed jan 2012 to advise that the timing chain was extended for repair. No notice was received and the address they had on file was correct. So here we sit with a worthless pos that nobody wants to take responsibility for. I would rather have it sit in the drive way and we share 1 vehicle than put 7000 into this car. I see that we are not the only people that have been taken advantage of by mazda. Has anyone called recently into customer service to hear the list of recall notices? It take 8 mins for the automated system to list them all. This company needs to take responsibility for it's worthless machines! If a class action lawsuit ever comes out, I will join in a heartbeat. Can the federal safety agency please look into this? I know that we are not the only people ... No time in life should an engine need to be repaired with only 76k on it!!!
My husband was driving home when he suddenly heard a loud whining noise then lost power. On the way to the dealer, he noticed it was smoking.
While driving the vehical started to make noise took it to first mechanic shop near bye and they told use the AC compressor was failing but it would be ok then on the way back home the car started to smoke from the compressor because the clutch had seized up we pulled over otherwise im sure we would have broken the belt causeing more damage.
My mazda began making a clanging sound at ignition. I took the mazda to sussman mazda in abington, pa. I was told that thought the warrant 5 yrs/60,000 miles had expired. However, mazda had extended the warranty on the vvt actuator and timing chain due to this being a know problem. I was asked to produce all maintenance records on the car. I did not have every single service record and was denied repair by mazda. I called the mazda corporate office and spoke with a representative. The representative told me that my claim was denied. I asked to speak with a supervisor but I was denied. I called back and was told that a supervisor would call me back on 08/30/12. It is 10pm and no one has called me back. It appears that mazda is doing everything possible not to repair a known defect on the mazda cx7. There are numerous complaint online of many cx7 owners going through the same situation that I have. I cannot drive the car due to fear off the timing chain failing.
While driving on interstate highway, loud ticking and whirring sound came from engine. Black smoke came from rear tailpipes and white smoke from under the hood. Vehicle lost power and stopped.
While driving home from work 8/23/12, my husband noticed that the A/C was not cooling and that the engine started making a squealing noise. He stated that the A/C compressor was failing. Fortunately for us, he made it home safely. If it failed completely while driving, the car (or he) could have died in the middle of the interstate.we had received the extended warranty notice for the A/C compressor. So, we took it to our local mazda dealership/service department for repair. The technician stated that we had just exceeded our warranty coverage. Our vehicle turned 5 years old on 6/30/12 and has 60,598 miles. He stated that we would have to contact the mazda corporate office to request assistance. The corporate representative stated that they would contact our dealership and take the matter under review. She stated that if they denied the claim there was no one else at mazda that would discuss this with us. I agree with other complaints filed to date...apparently, someone will have to be killed before anyone issues a recall.
I drove 200 miles stopped the car to get something to eat, when I restarted it a loud whistling noise came from engine and wouldn't stop. Called roadside assistance and it was towed 2 days later because it happened on a saturday night. It took 3days for it to be fixed and I'm not sure it is running properly. I also had the timing chain replaced at 60,000 miles. I will never buy another mazda.
Tl* the contact owns a 2007 mazda cx7. The contact stated that when driving over 20 MPH, there was a loud noise coming from the engine. The vehicle was taken to the dealer who stated that there was a faulty turbo engine charger which needed to be replaced. There were no recalls for the vehicle. The vehicle was not repaired. The manufacturer was notified who confirmed that there were no recalls and offered no further assistance. The failure mileage was 78,590.
While driving with my AC (air conditioning) on, it suddenly started blowing warm air. The car filled up with a burnt tire like smell and I quickly turned the air conditioning off. After giving it a few minutes and parking my car on a shoulder lane, I turned the air conditioning back on to see if it's going to start working again (while the car was still running). My AC was still blowing warm air but now there was a loud noise what appeared to be coming from the engine along with the burnt tire like smell. I decided to return home and have my husband take a look at it before I contact the dealership service to fix it. As my husband open the hood of the cx7 and I turned on the AC there appeared to be alot of sparks coming from the AC air compressor, right beside the engine. This looks as if it can potentionally set on fire. Mazda did send out a warrenty extension letter (ssp 81) back in 2010 for this very same issue. This warranty extension was covering vehicles up to 5 years/60000 miles.
I called a mazda car dealership to let the know I receive a recall letter and to make an appointment for my mazda cx7, the service man said if the car was not making any noise or smoking I didn't need to bring the car in. After weeks by after taking the service man advise I was driving on the highway in my cx7 mazda with my 6 month old grandbaby in the back seat all of a sudden pressing on the gas, the car just shuts off without any kind of warning in the middle of the highway; this highway is normally very busy especially with 18 wheelers, luckily there was enough power left for me to pull over out the highway before the steering wheel locked up. After waiting for tow truck driver in the heat with no AC and a 6 month old baby car was towed to a mazda dealership, which was closed. The next day serviceman calls me and tells me the timing chain broke, destroyed the engine and it was going to cost $4000 to be repaired,I had to bring receipts for oil changes, there was no sludge found; mazda offered $1000 as a good gesture, if they had found sludge they wouldn't have offered that. My car is still there; I can't get the car out because I have to make car payments and rent cars to get back and forth to work. What is it going to take before someone steps up and have mazda corp held accountable for these malfunction parts. Will someone have to loose their life before someone recognizes that there is a major problem!!!! There are to many complaints on line for the same reason for this not to be an issue!!!!!! I've been in contact with lawyers and the media I feel the public needs to know how this corporation is treating the consumers.
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.
Vtt timing chain broke on this vehicle which could have resulted in a horrific accident if the car had been mobile. Mazda has acknowledged that this engine component is faulty, because they issued a warranty extension to 72,000 miles in january 2012. This sort of engine failure could lead, and may have already lead to numerous accidents if they vehicle stalls while on the interstate or other roadways. Mazda should recall the engine part and reimburse customers who have had to pay for this mechanical failure.
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.
My 2007 cx-7 started making a loud banging noise when I started it (may 7,2012). I brought it to the dealership to have it checked out and they said it was my timing chain & actuator (vvt) and it would take $1350 to repair. I paid the money and it was fixed in a couple of days. On june 7th,2012 I started to realize that my AC was not working, but had decided to wait a little bit to have it fixed because I was still hurting financially from the last fix a month ago. Than on june 9th, 2012, I went to start my vehicle and it sounded like it was about to explode. I live in the country and the closest dealership is at least 50 miles away. So I brought it to my local repair shop and they told me my turbo is blown. The mazda dealership wants $80 to diagnose it and $5000 to fix it (that doesn't include my towing fees and the cost of fixing the AC). I've read all of the complaints online and everyone is saying sludge build up and mazda wants the receipts for all of their oil changes. I have all my receipts for the synthetic oil changes that I have had done to the vehicle on time (not to mention only filling the car with premium gas). Unfortunately, my car is up to 100,000 miles and they only extended the warranty to what...70k? So basically I have a car that I paid $16k for and is completely useless to me only after 100k miles. From what I've researched vvt's are not supposed to go out until what 250k-300k miles? And it seems a bit ridiculous for the turbo to go out after 100k miles....
Tl* the contact owns a 2007 mazda cx7. The contact stated that she had to replace the turbo in the engine four times due to sludge build up. The contact also stated that the most recent turbo failure caused the engine and transmission to fail. The contact took the vehicle to a mechanic and was informed that it was unusual for this failure to occur. The contact stated that the first turbo failed at 33,000 miles, the second at 58,000 miles and the third at 83,000. The manufacturer stated the turbos were not covered by warranty. The VIN was not available. The failure mileage was 33,000 and the current mileage was 90,000.
The air conditioner compressor went out. The vehicle began to have acceleration issues and started smoking like burnt rubber. Mazda has extended the warranty to 60,000 miles but refuses to replace the compressor beyond that mileage.
While driving on the freeway at about 70 MPH, my 2007 mazda cx7 randomly lost power. I was able to pull to the side of the freeway even though the steering wheel became very hard to turn. I was very lucky there were not many cars around me. The motor would only rev when I pushed the gas pedal. I had the car towed to a mechanic. The next day I was told that my motor and turbo needed to be replaced. The repairs would total to about $8,000. I already owe $15,000 on the auto loan. I only had the car for one year, the motor went bad at 60, 000 miles?. I'm a full-time student and a mom, my husband makes less than $30k a year. We cannot afford the repairs at this time. As a result, the car is sitting on our driveway.
While driving our cx-7 stopped running right in the middle of the road, we have found out that is a known issue with mazda cx-7 vvt pin/timing chain breaking. We were able to get the car stopped, but it was in the middle of the rode and was a hazard not only to our car, but other cars coming up behind us. We were unable to move the car and had to wait for a tow truck. Of course, mazda won't do anything to remedy the situation because the warranty has passed...even though they knew the problem existed in 2009. Someone will get killed one day.
After six months, we began to have mechanical issues with the vehicle. A diesel-sounding chug coming from the engine seemed off for an unleaded four-cylinder SUV. The common issue seemed to be a part called a vvt actuator. No recalls or service advisories had been issued for engine parts at this time. However, in january 2012, an entire half-decade after the vehicle rolled off the assembly line, we received a 'variable valve timing noise and timing chain noise warranty extension' notice by mail from mazda. A month or so after we received the notice, the vehicle began leaking oil. We took our vehicle into a roger beasley mazda center and had it examined. The oil cooler on the vehicle was beginning to fail. We explained the notice that we received in the mail and they were already well aware of these issues. We were told the engine had engine sludge and with it being a second-owner vehicle, we did not have the documentation to prove that regular oil changes had been performed. Instead, all repairs and replacements would come from our own pockets. The result ended up being a need to replace the vvt actuator, the timing chain, the oil cooler, and replacing all of the gaskets. The technician showed us a side-by-side of the current timing chain and the new replacement ' the used chain had literally stretched to be about half-an-inch longer than the replacement. We drove off the lot and hoped that the problems had been solved. Within two months of the repairs, the engine began making a high-pitched whining noise. My wife contacted the dealership that day while at work and they said to bring it in. On the way to the dealership, which is less than ten miles away, the vehicle died on the freeway. This ended up being the result of a blown turbocharger. Again, we had to take money from our nest egg to replace yet another part on this vehicle.
Vvt and timing chain replacement needed mazda knew these to be defective parts but only issued warning to me just this month and now that im over the mileage I have to pay for cost of replacing both ... Why hasn't the safety board looked into this very dangerous issue that will eventually cause someone to lose their lives ..... This most be addressed now!!!!!!!!!!!!!!!!!!!!!!!!!!
Purchased 2007 mazda cx-7 with 65,000 miles. At the time was told it had a new turbo. Had the vehicle 2 months and the erg valve died (technician stated they should last 100k miles) was replaced at my cost of $850. When replacing the erg valve they also noticed a worn tube that will cost an additional $180 at my cost. They also noticed the new turbo was smoking and this was an extended warranty coverage from mazda to 70k miles (I was at 68,5000). They are adding a whole new pcv vent kit at dealer expense). Now I am hearing a loud ticking noise whenever I turn on the A/C which could be either the vvt timing chain or the air conditioning system. Both are known defects of 2007 cx-7's and will cost about $1,000 to fix for each issue. The timing chain is covered until 70k miles so I'm trying to get this fixed by the dealership now before I run out of warranty. However, the AC issues were only covered to 60 k miles and I am beyond that coverage so I will have to fix that at my cost. If you do a quick google search you will see extensive documentation of these same issues amongst many mazda owners. Mazda refuses to recall such parts and only this year (4-5 years later) did they extend warranty coverage on some known defects knowing that most people would be beyond the warranty limit of 60/70k miles. There are many reports of engines seizing due to the AC and timing chain issue. I am quite frankly terrified to drive this car and seeking a very comprehensive extended warranty to hold me over until I can trade it in and get something reliable! I work for a car dealership so I know that these issues are legitimate with this vehicle.
After owning our 2007 mazda cx-7 for over 5 years, we received an extended warranty notice that the timing chain was defective and at risk of breaking. Having noticed a slight ticking noise already, we immediately took it to the dealership where it was purchased. They examined it and notified us that even though our car was 5 years old and at risk of failure due to a factory defective part, the warranty was only extended to 70,000 miles and mazda would not cover any costs since our odometer was at 80,000. I went home, did some online research, and discovered that our year and make of vehicle also had a tsb from mazda for a defective timing vvt actuator that could cause the same clicking sound. We had never been notified of this by mazda or the dealership. I called mazda customer care immediately and they assured me that the timing chain was the source of the clicking noise. Two weeks later the vvt actuator in question did fail. Mazda assumed liability and replaced the defective vvt assembly and timing chain, but refuse to cover any of the costs to repair the severe damage caused to our engine as the direct result of this part failure.
We have a mazda cx7, 2007, that we purchased brand new in april 2007. We have had all oil, filter and other services by our local mazda dealership in accordance to mazda guidelines. Recently while driving 70 MPH down interstate 81 with our 10 year old son in the car, our mazda stopped working. Lucky for us we were able to get off of the road and call a tow truck, who took us to a local mazda dealership where we had to leave the car until monday (it was a saturday afternoon) and find other means of transportation home (70 miles away) on monday morning my husband received a call from mazda stating that our vvt plug came apart causing the engine to jump time and that we could pay to have a vva kit ordered and installed to see if it would fix the problem, at a cost of $1300, but this may not fix the problem because due to the plug coming apart our engine lost compression. And if this was the case, we would be out the $1300 and it would cost an additional $7950 for them to replace the engine. When we questioned them about the "service bulletin" released re: the problems they were having with this vvt they said that they really couldn't help us with this.... Our car was over in the mileage... Well to me a problem they recognize and admit to they should take care of no matter what.. Had we have know of this pending problem, we would have opted to have this kit replaced long ago and gladly paid the $1300 instead of being out a car, that we really have enjoyed, and now looking for someone to replace an engine!! Oh and by the way.. Don"t let mazda do this for you!! It is much cheaper to have your engine rebuilt and replaced by an outside source. We have contacted a machine shop in virginia who will pay shipping and do this for us for $3000 and we have a local mechanic that will do the work for $1000 oh and they give you a 5 year warranty!! Mazda needs to be responsible.
Tl* the contact owns a 2007 mazda cx7. The contact started the ignition and a loud clunking noise emitted from the engine. The vehicle was taken to an independent mechanic, who stated that the faulty variable valve timing would need to be replaced. The manufacturer mailed a notification, which indicated that the replacement of the variable valve timing would be free of charge; however the vehicle was ineligible because it exceeded the 70,000 mileage requirement. The manufacturer was notified of the failure. The approximate failure mileage was 85,000.
My 2007 mazda cx-7 starting making a popping noise and began losing power on april 13, 2012. I drove my car to the dealership and was told that the timing chain and turbo charger are bad and need to be replaced. My car has 80,477 miles on it and therefore, nothing is covered under warranty and I cannot produce all oil change receipts. Thus, it is going to costs me $3,000 to get fixed. I am very disappointed in mazda for not fixing a defect that they are clearly aware of, regardless of the mileage! I never received a recall letter and I have been a loyal mazda customer, purchasing 5 mazda's over the last 12 years! I travel with my job so I do put a lot of miles on a vehicle (averaging 2,000 miles per month) but I find it utterly ridiculous that a car has major defects at 80,000 miles! Please help and stop mazda from taking advantage of consumers!
