2007 Mazda CX-7 engine complaints
Page 7 of 12: complaints 161 to 190 of 316, newest first, as owners wrote them.
Smoke and rattling and low oil prompted me to make an apt at my local mazda dealer only to find that my turbo has blown and my vvt valve and timing chain. (the truck is a 2007) I was told that I should not drive the truck as it would be a safety issue with 2 kids. So after my quote of 7000.00 to fix the truck I thought I would do some research online only to find that there are as many as 50 people with the same problem in the same truck with the same year~!! Why wont mazda stand behind there product and put out a safety recall on this issue? I was told to find this site and lodge my complaint. Hope this will do some good !!
I started to accelerate after coming off of an exit ramp when I heard a noise from the engine then I started to lose power. Immediately after that when I depressed the gas pedal to accelerate, a grinding noise occurred. I was able to get the vehicle to a parking lot. I had the car towed to mazda dealership who informed me that the turbo had failed. They want all maintenance records for the time I have owned the car in order to make a determination of whether it will be covered under warranty. I purchased an extended powertrain warranty which covers the engine and turbo to 100,000. But it appears they are stating it is due to improper maintenance as I cannot produce all my oil change receipts.
Timing chain broke.
Purchased my vehicle 15 months ago at 38,000 miles. In october, I was driving along and the car stopped running. No warning, nothing on the dash lighting up, the vehicle just started loosing speed. The steering was going as well. I put the vehicle in neutral to try and get the steering back and it was a hard steer to the side of the road. I tried starting the vehicle and it would turn but not start. Two tows later, I find, to my surprise at 62,000, that I need a new engine. My timing chain either broke or has derailed. This all happened on october 22nd. It is now november 10th and I still do not have an exact diagnosis nor a vehicle. Yes, warranty is done at 60,000 miles, but what vehicles loose and engine at 62,000 in this decade? And, thankfully, I was not on a highway when this happened as I'm not sure what happened to the steering in this whole process.
Tl* the contact owns a 2007 mazda cx-7. The contact stated that there was an abnormal knocking could be heard hear from the engine when first starting the vehicle. Later, the vehicle stalled while driving and was taken to a local mechanic. The mechanic advised that the time belt was fractured and the engine needed to be replaced. The contact did not call the manufacturer. The failure mileage was 100,000.
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 , 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.

I have had my 2007 mazda cx-7 for less than one year. I stopped at a red light after exiting the highway and my car engulfed in thick white smoke. I had the car towed to a local shop per my insurance company to have it checked out. The repair shop at first called to tell me it was the starter, and that it would cost 600 to fix it. Come to find out that not only the starter blew, but it also ruined the alternator as well as the fuses on the battery. I was told by mazda that this is not a common occurrence. The total of the repairs is now over 1200. The vehicle has been meticulously maintained throughout its lifespan and is at 92,000 miles.
After driving down the expressway the air conditioner stopped working. I brought it to the mechanic and was told the air compressor kit went out and it is $2,300 to fix.
Tl* the contact owns a 2007 mazda cx-7. The contact stated that the engine was started and a rattling noise was heard from the engine. The vehicle was taken to the dealer where the dealer confirmed that the variable valve timing actuator failed and would need replacing. The manufacturer was not contacted and the vehicle was not repaired. The failure and current mileage was 69,000. The timing chain and belt was replaced. Updated 11/10/2011
My 2007 mazda cx-7 broke down without warning. Found out the timing chain had snapped as a result of a piston blowing. I have been told the turbo seized and caused excess pressure causing the piston to blow and breaking the timing chain. Have found many people online complaining of same thing happening to their cx-7.
2007 mazda cx7 - turbo broke while driving causing tremendous squealing sound and loss of power. Able to drive home and had towed to mazda dealership. Service mgr called me saying they checked car over and could not find anything wrong with it and asked if I wanted an oil change. I said go ahead with an oil change but there is definitely something wrong with car and to check again. Mgr called back later saying a screw in the turbo had come loose, turbo was broken, I needed a whole new engine and it would cost $9,000. Car had 34,000 miles and still under warranty. I fax'd copies of oil change receipts. Mazda north america denied warranty claim saying my oil receipts were unverifiable. Mna told me they would not verify my receipts. They claimed there was "sludge" and that caused it to break and I hadn't taken care of it. It was a leased vehicle with only 3 months left to pay. Had just started a new job after being unemployed and had to rent a car costing $650 and then go buy a kia causing extreme financial & emotional duress. I told the serv mgr that I could have been killed and found out these cars were engineered incorrectly causing them to get too hot causing "sludge", that I knew he knew about the issue because a service bulletin had been released jan 08 stating the exact problem, and mazada was trying to avoid a recall. He stated that it was "mazda north america", and not him and if it were up to him he would fix the car under warranty. I told him I was under extreme duress and that mazda should do the right thing and fix the car. They refused so had to leave the car at the dealership.and walk away. Now mazda says I owe them $5,000. Filed complaints with bbb and attorney general. It is an outrage that so many mazda cx7 owners have had same nightmare and mazda does not care about the safety of it's customers. Please help us.
My wife and I have a 2007 mazda cx 7 with 68000 miles on it. On august 13th my wife was driving with my 9 month old daughter and noted a funny sound with loss of air conditioning or change of quality of air conditioning. She reported smoke and noise that followed. Luckily she was on a back road and close to her destination and was able to arrive at the destination without having to drive far. She phoned me and gave me the news and I immediately knew it was the air conditioning compressor. This is due to research I have done that the mazda cx 7 from 2007 is notorious for the air conditioning compressor seizing up. Luckily my wife was aware of this issue and parked the car and had it towed to a local mechanic to be repaired. In the meantime, I had emailed mazda and reported the issue, the part had the warranty extended to 60000 miles, so I was already irritated to know that this happened 8000 miles outside of warranty on a part mazda already knew was defective. They have yet to respond to my email and that was already more than a week ago. The car is repaired now and not by a mazda dealership as I refuse to give them anymore of my money. I am very displeased with the lack of customer service and lack of ownership by this company over an issue with this part they clearly know exists. This part is clearly defective and dangerous and should have been recalled and replaced. I think it is ridiculous that they extended a warranty, but will not just replace a defective part they produced that could cause personal harm and danger to not only the owners of this car, but other people on the road around it.

7/6/10(25,000 miles) driving "piece of crap" from w-pa to phila after 1 1/2 hours in car airconditioning gets hot & loud noise starts. Able to pull off main highway &find a sears auto shop they say air compressor in my pice of crap (2007 cx7) has fallen apart - they don't do this work-I needed a mazda dealership-they wouldn't recommend me driving home! It's a holiday (july 4th celebrated this day) I have no idea where a dealership is-I am over 200 miles from home - everything else is closed. Found a hotel to stay overnt & search for a dealership. Found 1 abt 20 miles away. Next day (praying the whole 20 miles) that piece of crap would make it to the shop. It did I explain situation to a non-caring, won't look me in the face mechanic who finally states (after 3 hour wait) my warranty expired 5 days prior & it would take 3 days to get part & fix. Here I am 200 miles away from home, in a not so racially diverse area of west pa- leaving for vaca the next day- & I can't get home!!! It was like pulling teeth to get a rental car # & a taxi cab # from these people. I was finally able to get home via 8 hour bus ride & go on much needed (after this ordeal) vaca, however I still had to pay over $800 & pick piece of crap back up. I complained to mazda couple times &finally got letter that they were extending the warranty for air compressors to 60,000 so I got $ back, but not for the hotel stay, taxi ride to bus and bus ride home and back up there! Couple other problems came up later -white smoke out of tail pipe after ideling, dealership couldn't find a problem, also saw something leaking, dealership couldn't find anything leaking--- 8/4/11 (31,000 miles) took piece of crap in for a noise it's making at start up. Vvt gone bad, but still under the powertrain warranty so got fixed. What's next??? I'm afraid to drive to far in this car!! Can't take driving vacas-- gonna get rid of "piece of crap" prior to the warranties expiring in 2012! Got to!!!
Driving on the freeway 65 miles per hour, engine shut off... Pulled to side of road. Car towed to mechanic. Diagnostic with two quotes timing chain snapped bent valve, need to replace the engine. I have been reviewing forums and have found this is an issue with hundreds of mazda cx7 2007 models. My car is at the 61,000 miles mark. If so many people are having the exact same issue its no coincidence, thankfully on the day my engine shut down was in the far lane that I could pull over. Someone else with this car might not be so lucky. Mazda needs to recall and start doing something.
2007 mazda cx-7 awd grand touring with 39k miles. Car was being driven had sudden loss of power while traveling down road. In traffic car suddenly slowed to crawl at 20mph once car was navigated to shoulder and stopped it would not restart. The vehicle was towed to dealership where they have stated that the timing chain or vvt has failed resulting in timing chain failure thus total engine failure. Known problem reported numerous times and yet mazda dealership has informed me that with the maintenance records provided they are refusing repair. These timing chains are failing on cars with 19k-60k miles, not within normal maintenance.
(march/2011) light came on around 65k miles. Took it into dealership and they said oil was low and yvt needed replacing. Cost was around 2500. No reason why oil was low and last changed by mazda less than 7500 miles before. Also full service was done at that time. (june/2011)while on highway at high speeds the car lost acceleration, emitted high pitch whirring. And became difficult to control. Towed to dealership and it is being blamed on bad turbo. No reasoning behind failure other than saying oil change issues. The problem is that mazda is the only entity that has ever worked on this car at least twice per year for check ups. There also appears to be others with same reported problems to both turbo and yvt.
2007 grand touring mazda cx-7 has well known vvt issue causing oil to burn, in spite of regular oil changes and all recommended maintenance. We are original owners and know how car was maintained . Timing chain went at 62k miles, just out of warranty. After that service, drove 1k more miles and noticed loss of acceleration. Took car back to dealer, and they advised we needed a whole new engine, which they would not cover, aside from a 20% goodwill offset. Spouse won't let me operate car any longer in fear it will break down causing accident. Unsafe vehicle.
My wife was on her way home when there was a funny buzzing or squealing noise coming from under the hood of her 07 mazda cx7. She pulled over and there was smoke coming from her right front tire area. She then had to call our insurance roadside assistance to have it towed to our local service repair shop. Later we found that the AC compressor was seized and the belt was melted. After further research upon this matter I am finding that there is an astonishing number of other people that have had the same issue. Come to find out mazda is telling people that this is a known issue and to come in and pay $1500- $2500 to have the defective part replaced. This is unacceptable!!!!! My wife is on the side of the freeway at rush hour waiting for a tow truck and mazda could have had this issue resolved... How many other people have to be put into dangerous situations before mazda steps up and takes care of a known problem..
A/c compressor died.
Mazda sent a letter to report a known issue with the 2007 and 2008 cx-7 in august 2010. The A/C compressor was creating issues and mazda extended the warranty to 60,000 miles. The letter indicated that no action was needed unless you heard a strange "noise". Based on my experience and those of others, the problem occurs with no warning and all of a sudden the A/C stops working and smoke begins to come from under the hood. The issue can also cause the power steering to go out and the car to stall so how can this not be a safety concern and not be considered a recall? The warranty is only extended to 60,000 miles and there are many cases where the problem does not occur until after 60,000 miles. Is mazda just hoping that most will happen after 60k so they don't have to pay for the repair? I had the dealer check it during a routine service but they wouldn't repair it unless there was a "noise". While on vacation, my car A/C stopped working and started to make the "noise". Then smoke started to come out from under the hood, frightening my kids in the car. We were traveling on the interstate at the time and had to find a safe place to pull aside. We barely made it to the nearest mechanic before the belt broke. My car had 65,000 miles and mazda will not pay for the cost of the repair, nor the cost to rent a car in its place. Now I am out almost $1,700 for repairs and rental fees. This issue needs to be investigated. Does someone have to die in an accident as a result for mazda to be held accountable?
Tl* the contact owns a 2007 mazda cx7. The contact stated was driving 55 MPH when the engine oil shield cover separated from the vehicle. The contact stated that the vehicle with the dealer one day prior to the failure for routine oil change. The vehicle was taken back to the dealer who performed a diagnostic and located the failure at the engine oil plastic shield cover. The dealer advised that there was a possibility that the screws may not have been placed back correctly. The dealer replaced the oil cover shield with the same defected plastic and there were no further repairs. The failure and the current mileage was 70,000.
I own a 2007 mazda cx7. Since I bought the car, at 29k miles I had to have the fuel tank replaced. At around 34k had to have the turbo looked at because of black smoke blowing on my bumper, mazda replaced the pipes. My pipes were still smoking, had to take off work, take car in again because of black smoke, mazda tried replacing rings in turbo, still blowin bluish white smoke, now getting turbo replaced. I had the air compressor replaced a about a month ago. Now I have a ticking noise coming from engine and I'm scared the timing chain will break soon. Mazda needs to replace the timing chains on these models. I think mazda should do the right thing an recall this model, yr before someone gets hurt or breaks down in the middle of nowhere with kids in the car.
