Engine Belts And Pulleys problems of the 2008 Mazda CX-7

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.

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.

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.

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).

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 Mazda 2008 cx7 sport - purchased new on 11/28/2007. I have 62,500 miles on the vehicle. It was towed to the dealer on 6/22/2010 with loud whining noise and loss of power. Dealer said the turbo is malfunctioned. Over the next week the extended service company for Mazda requested maintenance records. I had the oil changed outside of the dealer some of the time. They looked at this and declined the warranty repairs. I kept calling and they agreed to send out an independent adjuster. He noted a "sludge" build up on the oil return hose bolt to the turbo. They declined my warranty coverage. I am having to pay $2500 to repair. I have been doing research online and this vehicle is having numerous issues with sludge buildup. This comes from the engine running to hot and breaking the oil down to create blockages that ultimately affect the turbo or other internal engine parts. If you look on edmunds website you can see their are others with the same issue. Mazda will not make the recall or assist the consumers. We follow their recommendations on oil change and are getting no assistance. I am afraid that I will have additional issues once this is repaired and they will decline future service. Hat can you do to help? I actually have the dealers printed copy of where they repaired the timing belt tensioner in April at 57k miles. According to the supervisor for customer service at the extended warranty office his computer records show they repaired the serpentine belt for less money that the dealer records I have in hand. What is going on this just does not seem honest. I need help and there are others with the same situation over the last year - some having to spend $7500 + out of pocket to repair their cx7. Please call me for help.

The contact owns a 2008 Mazda cx7. While driving black smoke was expelled through the vents of the vehicle. The vehicle was towed to the dealer. A technician from the dealer stated that the air conditioning clutch and belt had failed. He then added that the failure was a manufacturer defect. However,the estimated cost for the repair was $1,243. 00. The manufacturer took a report, and a representative stated that they would assist with the repair. The vehicle was in the process of being repaired. The failure and current mileages were 42,000.
