Tl* the contact owns a 2008 mazda cx-7. While driving 10 MPH, the vehicle began to decelerate and all the warning indicators illuminated on the instrument panel. The contact stated that the engine stalled. The vehicle was taken to a dealer where the failure could not be determined. The vehicle was not repaired. The manufacturer was not notified of the failure. The failure mileage was unknown.
Car had severe oil leak found during an oil change with no oil left in the car; however there was never oil on the ground - I park in the garage. I took the car to the dealer for a diagnostic test, they did the dye test and found the leak near the oil cooler from the seal/gasket. This is a very expensive part and it appears to be very common after 80k miles from my searches online. Please investigate as this is very unsafe and needs to be addressed.
* engine issues when the A/C compressor locked up. This is a known issue in this make and model. This happened around 36k miles while I was driving on a freeway. We had to coast into the next exit. * engine knocking issues. They still persist and started around 50k miles. * engine resistance. Alongside the knocking there seems to be a good amount of resistance when taking your foot off of the pedal for acceleration. * they added a factory extension to the radio for the ipod. Ever since they installed this, the rest of the electrical components have been overloaded. - headlights go out frequently. This concerns me as my wife drives the car and I wouldn't want both to go out at the same time. - the battery won't hold a charge if not driven for a few days. The dealership acknowledged that the radio has a 'parasitic draw' on the battery causing these issues, but refuses to take responsibility for their installation. Their solution is to charge $800+ for a new head unit, which is outrageous since I never did anything to the factory head unit.
My mazda cx7 - 2008 has only 44,000 miles and the engine light went one and after bringing it to a mechanic and checking the codes with a computer, it came up that the egr valve needs to be replaced. All the mechanics that I talked with were really surprise and asked me if the mazda cx7 - 2008 has a recall on the egv valve because it is not normal that with that little miles the egr valve need to be replaced. I have checked on the internet and I'm seeing many other owners that are having the same issue. I think there is a factory defect with the egr valve for this model.
I have white smoke coming out of my tailpipe when it idles. I also have a burning oil smell in my car. I have to roll down the windows when I get into my car. I have a 2 1/2 year old and I cant imagine its safe for her to breath this in. I took it to green mazda in springfield il to be repaired, this is a known issue with this vehicle. They installed a ventilation kit. That did not solve the problem. I took it back and now they say there is no problem. So they saw a problem and installed a ventilation kit but now that is doing the same thing there is not a problem. The next step is to replace the turbo, which they will not do. This should be a safety recall.
On sunday, january 4, 2015, I was driving my 2008 mazda cx-7 and I stopped at a stoplight. When I tried to take off when the light turned green, my car hesitated and when I pressed on the gas peddle a little more, it still hesitated then finally took off. All of a sudden, I heard an extremely loud popping noise, and then thick, heavy white smoke started to come out of the tailpipe. The white smoke then started flowing out from under the hood, and it started to come into the car through the air vents. When I tried to pull over and put the car in park, it wouldn't shift into gear, so I pushed the parking break, and it finally stopped. I got out of the car and when I went to grab my purse, I saw fire coming through the bottom air vents ( the ones that blow air on your feet) so I grabbed my purse as quickly as I could, and ran away from the car. Then, I saw part of the engine fall out of the bottom of the car, on fire, and burn into the street. About 5 seconds later, the whole entire car burst into flames. All of the doors were closed, but the intensity of the fire blew both of the passenger side doors open, and blew out all of the windows (including the sunroof, which was closed at the time). When the firefighters finally put the fire out, the car was still smoldering and everything inside was melted. The steering wheel, the seats, the door handles, the mirrors, everything. The fire was so strong that it blew the hood back onto the windshield. All that is left of the car, is just the metal frame, and the engine. The car has a 4 cylinder engine with a turbo feature on it. I believe that is what caused the fire and made the loud popping sound initially.
I write to express my disappointment at the quality of vehicles mazda is putting out, and the lack of response mazda's customer service department offers its customers. In 2008 I bought a 2008 mazda cx7 and this car has given me nothing but problems. From the faulty wiring that always blows out the headlights, to the power windows which sometimes turn off and turn on, to the exhaust fumes that can be smelt inside the car, I've complained about all of it and spent countless resources and time trying to fix it all. The last straw came about a month ago when I was informed that my vvt adjuster and chain were out, the turbo was out and the engine was failing and it would cost me close to $4,000 to repair it. We're talking about a car with only 75,000 miles. According to my mechanic and according to edmunds.com reviews these are all common cx-7 problems and mazda just won't own up to them.
The oil cooler on my 2008 mazda cx-7 began leaking around the rubber o-ring a few weeks ago. My mechanic called ferman mazda in brandon, fl to get a replacement and was advised by the service department that the old style oil cooler had problems and mazda re-designed a new one, and now mazda owners have to spend over $400 to buy a new one because the rubber gasket and oil cooler are not manufactured anymore. Oil has covered my engine and the plastic engine cover underneath the vehicle. The heat from the engine can cause a fire if it sprays up near the plugs/starter. There is an obvious problem with the oil cooler, however ferman mazda does nothing to fix the problem for their customers.
While on a freeway off-ramp car started to idle irregularly accompanied by white smoke and a loud whining noise. Identified problem as A/C compressor. Turned off air conditioning; smoke and whining seemed to stop, and I was able to drive it the 15 miles to my mechanic.
Vehicle started making a loud whining noise while driving at 55mph. White smoke started pouring out of rear end. We thought the car was on fire. It then wouldn't get over 20mph. Pulled over and called a tow truck.
I had smoke coming from under the hood. Ac compressor was burning up, and entire AC system needed to be replaced, only for the AC to stop outputting cool air on hot days unless I'm driving over 55 MPH.
As I was driving my mazda ( with a turbo engine) along the highway it began to decelerate on its own and making a loud knocking/grinding noise. It stopped on the road going up a hill with no turnouts. So it appears that the turbo blew up. It will start, but I cannot go anywhere. I have also had to replace gaskets on my oil filter housing unit, as the stock gaskets were faulty and causing a severe oil leak. Also, my emissions regulation ( egr) valve is bad and therefore will not pass smog. Each of these issues I am seeing more and more complaints about from other owners of the same vehicle. Mazda has made a horribly defective car and refuses to do anything about it except to claim owner negligence. I bought my car with 40k miles on it and it has been falling apart from the start. There is absolutely no excuse and this is not owner negligence, it is mazda negligence and refusal to make anything right on their completely defective vehicles.
The AC in this vehicle has always under performed. It did not get really cold and had to be run on the high setting constantly. Just last week the compressor failed completely.
Tl* the contact owns a 2008 mazda cx-7. The contact stated that while driving 20 MPH, the vehicle made a popping sound and white smoke emitted from the rear of the vehicle. The contact mentioned that the vehicle stalled immediately after. The vehicle was taken to the dealer. The technician diagnosed that there was hole in the piston caused by the turbo charger. As a result, the engine needed to be replaced. The manufacturer was made aware of the failure. The vehicle was not repaired. The VIN was not available. The failure and current mileage was 78,000.
Egr valve failure on a 2008 mazda cx-7 with 47,500 miles. I had never heard of a egr valve before my check engine light came on and I took it to the local auto parts store to have them tell me the error code. Took it to the dealership and they told me that the warranty for the part was 60months/60,000 miles. While I was way under on the miles, I was 5 months over on the time. Since this was my 3rd trip into the dealership over the past 5 months dealing with problems/maintenance with my cx-7, I asked why this particular part failed. I was told that it was due to the negative effects of ethanol. After some quick research, it is clear that 2007-2008 mazda cx-7 has serious problems with the egr valve. It will cost me $650 to fix. Mazda should have been forced to recall this part since it looks like it was defective from the start. Was told that a new replacement part for the egr valve would be put into the vehicle which will not break due to presence of ethanol in gas.
The gasket on the oil coolers on these cars are defective. I have an oil leak from this gasket that puts me at risk for an engine blowout. I will have to replace the entire oil cooler at a cost of $500+ because the gasket can't be purchased separately. Mazda needs to take responsibility for this before people get stranded on the road. If you search this oil leak online, you find dozens of posts about this happening to other cx-7 owners. This is a crossover SUV geared towards families. I drive my kids around in it and now am very concerned about the safety of this car.
Had to replace the A/C compressor that went bad, was a recall on them but my warranty was out. Then now 11/8/13 I am being told that my egr valve is bad and needs to be replaced and it so happens guess what the emissions warranty has ran out. I have seen a lot of complaints on line about the A/C compressor and now the egr valve.
Tl* the contact owns a 2008 mazda cx-7. The contact stated that white smoke emitted from the tail pipe. The vehicle was taken to the dealer who stated that the failure was due to poor maintenance and that the turbo needed to be replaced. The contact also mentioned that the failure was previously experienced. The technician also stated that there was a blown head gasket. The vehicle was not repaired. The manufacturer was contacted about the failure. The failure mileage was approximately 81,000. Updated 12/31/13*cn the dealer informed the consumer the turbo failed due lack of maintenance and not enough oil changes.
Sudden loss of power as the turbo stopped working. The mazda dealership claimed that the turbo broke due to sludge in the engine. There was a lot of sludge in the engine, however, the car was well maintained with regular oil changes. It seems that the median engine temperature is hotter than is appropriate for the specified oil in the owners manual. This results in oil burning and sticking to the inside of the engine. Eventually a piece of "sludge" will come loose and clog the oil tube to the turbo, resulting in the turbo unit overheating and breaking. Mazda seems to be aware of this problem as they were pressured to extend the warranty on this part. However, the problem is very serious and there should be a recall of the turbo unit and clarification in the owner's manual. Mazda has yet to agree to fix the turbo and "sludge" in my engine. They are still insisting that I did not maintain the vehicle well. Fyi- I was a car designer with honda/acura for 4 years who designed the 2009 - 2012 mdx. I am stating this because I know SUV's and how to maintain them very well.
Tl* the contact owns a 2008 mazda cx7. The contact stated that while the vehicle was parked and unoccupied, oil was leaking from the engine compartment. The vehicle was taken to an authorized dealer for diagnosis. The engine oil cooler and engine cover were both repaired. The manufacturer was notified of the problem. The failure mileage was unavailable. ...updated 04-22-14 *bf the consumer stated the timing chain and vvt actuator was a recall item. The vehicle had not been repaired. Updated 04/28/2014
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.
Mazda got stuck and had no power the first time second time happened october 9,2013 car kept shutting off and finally could not move. Turbo once again twice in 5 months and I only had this pre-owned vehicle for 7 months.
The oil cooler above the filter is leaking very bad, and I need to replace the gasket,but I had no prior leaks before and it was hard to start my vehicle. You can't just buy the gasket for the cooler, unless it's the newer silver oil cooler, the part alone is at least $400, but there seems to a frequent issue of this with many others, on the 2008 mazda cx-7.
Timing chain went out . Mazda is trying to say it sludge from poor maintenance . Even though we have all receipts since we owned it for oil changes. We just purchase this cx7 in august of 2012 with almost 28000 miles. Now a year later and 40000 miles it needs a motor.
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.
Tl* the contact owns a 2008 mazda cx-7. The contact stated that while driving approximately 65 MPH, the vehicle stalled without warning. The vehicle was towed to a dealer where it was diagnosed that the turbo charger and the engine needed to be replaced. The manufacturer was notified of the failure. The vehicle was not repaired. The approximate failure and current mileage was 100,262.
There was a knocking almost as if the car was a diesel, brought the car to milford mazda in milford ct after purchasing the vehicle a month earlier at bobs in milford ct. The mazda dealer replaced the vvt december 2012 the service engine light goes on and I take it to the local garage and they get a code for camshaft, I bring the car to mazda who tells me upon arrival with out even looking at the vehicle that I need a new engine and it wouldn't be covered under my extended warranty because they are sure there is sludge in the engine, yea same story everyone else gets. I faithfully had my oil changed every 5,0000 miles max as this was drilled in my head growing up from my dad. Approximately some time in march I was driving to work I get this loud whining sound coming from the engine and the car loses all power the turbo went. I have a new turbo installed and still supposedly need another vvt just 2 years after they replaced this part and now there is a humming/whining noise coming from the rear of the car not to mention (2) tie rods are bad. This car is no doubt a piece of crap that I still owe 13k on and mazda corporate will not even return my call. There has to be something that can be done with all the same complaints.
First the turbo went out and now the engine!!!
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.
