Manifold/header/muffler/tail Pipe Problems of Mazda CX-7

Took car to Mazda for airbag recall, replaced airbag but Mazda tells me the actual sensor that tells the airbag to deploy does not work and its my responsibility to fix it. Prior to the recall the sensor did not come up on the dash after the recall I now have a light on my dash and Mazda is telling me its 700. 00 to replace fix and part and labor. Electrical car shorts out all the time, windows, engine, lights work one day not the next when doors open. Car stalls out when driving and system reboots. Other issue is I have spent 7 thousand dollars in repairs on this car. I have black smoke coming out of the tail pipes, ive replaced thousands of dollars in parts. Engine light wont go off. I took it finally to auto zone for a free engine diagnosis to get a print out and now the emissions valves are showing faulty. Its burning 2 quarts of oil about every couple of weeks/monthly basis. Ive replaced motor mounts, coolant/oil parts, air compressor, headlights, bumber, wiper blades, electrical control panels, rocker arms, spoilers that have cracked with weather, the car still needs another motor mount, I now have a knock in the engine like its the lifters and I still have another year on this 5 year loan on this car. I have to keep rolling payments to the back of the loan to keep up with the repairs. Its very frustrating. Ive never had this many problems with any car I have purchased ever!!! even the parts department at Mazda has said what do you expect you purchased a plastic car on wheels. Is there any other people experiencing problems besides myself?.

I lost power to my 2010 Mazda cx7 while going 60 mp downhill in a mountain pass. My car went from 60 mp to 40 mp in about 30 seconds. I immediately pulled over as black smoke poured out of my tail pipe and had the car towed. My mechanic said the turbo was blown, which cause the car's oil to completely burn up, causing damage to the timing chain and engine. All of the oil was gone in a matter of a few miles. The car had been up to date on all maintenance. A new turbo and engine was needed on a car that had 74,000 miles on it.

While driving on the turnpike my car started to make a whining noise then smoke came from tail pipes. After having it looked at the turbo charger has gone bad!.

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/cn the dealer informed the consumer the turbo failed due lack of maintenance and not enough oil changes.

I purchased the 2008 Mazda cx7 about 2 weeks ago and already replaced the compressor I first had white smoke coming out the tail pipe well I didn't think anything of it until someone told me that is not normal so a week later I started hearing noises like a diesel truck and a knocking noise so the next day I went to the dealership that sold me the vehicle and we drove the vehicle and he stated it was fine he then drove again and the vehicle locked up and they told me the compressor locked up now I'm hearing a ticking noise from the engine and they stated it was normal but it still concerns me cause reading other statement have me worried that the engine vavle will be next and I don't have money to repair a vehicle I'm a single parent of 4 kids.

My wife's 2007 cx7 was in a parking lot. My wife started it up, came to a stop sign and the car died without warning. It had 65,000 miles on it (5000 over the warranty) and wasn't even 3 years old. We had always gotten regular oil changes and had just had one the week before. We had it towed to the nearest Mazda dealer. The first time I talked to a service tech he mentioned the timing chain breaking. Later, they explained it as a valve (variable valve timing actuator?) failing and causing oil chain failure (jumping the gearing). My bill ($7500 - new engine) only states internal parts failure. They tried to indicate the oil was dirty even thought the oil was changed less than a week prior. After reading through many cx7 forums online it seems they were trying to build a case for engine sludge to cover themselves. Less than 2 months later replaced intake manifold shutter valve and had to flush and reseal brake lines. Went to kerry Mazda of ky to originally purchase a 2008 because of low finance deals. They shifted my attention to the 2007 (3500 miles) and I agreed because of the certified new (100,000 miles) program. When I found out I didn't have 100,000 mile coverage I went back to dealer and we pulled the paperwork and under the warranty it says certified and also remainder manufacturer's warranty. So it ends up they sold me a used car as new and I didn't even get the financing of a new car - very shady. Mazda corporate was of no help either, simply stating the car was out of warranty and there was nothing they could do. Needless to say I will never buy Mazda again. I will also make sure I don't trust what they say and make sure I read and understand every page even as they try and rush you through it. I fear someone will be killed when their cx7 suddenly stops on a busy highway. Hopefully, Mazda will address the problem before that happens.

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!!!.

Purchased my 2008 Mazda cx7 brand new 12/08/2008. Started noticing white smoke coming out of the tail pipes while idling and I lived in south florida at the time. Dealership stated that the car was leaking oil and they wanted to fix the problem by putting in oil that would cost over $100 per oil change. After putting in the oil the problem continued. Took the car to the dealership again and they then stated that the only fix would be to replace the turbo and that I had to contact corporate to get it fixed. After speaking with corporate the turbo was replaced, but I am now having white smoke coming from the back of the car again and I am at 45,500 miles. This is a problem that I see listed often on this site and with some cars starting on fire. I hope that would not happen, but if Mazda has changed the turbo due to this problem in newer models a recall should be looked at to keep the problem from occurring.

I purchased a brand new 2007 Mazda Cx-7 in April 2007, the vehicle started experiencing engine problems in September 2007, I was told it may have something to do with the vvt (variable valve timing) and timing chain. The vvt was replaced by the dealership a short time later; however, not the timing chain. After the vvt was replaced my vehicle starting to experience thick white smoke coming out of the tail pipes. My dealership technician advised this was due to a turbo issue with the engine. All of this occurred within the first couple years of my ownership. I have had the turbo repaired (out of pocket expense), as well as the vvt (2 times) and the timing chain it all seems to no avial. The car is revving very high on cold start ups and is now experiencing a code as of the last couple of days that is stating there is a decarbonization issue with the engine that is linked to the timing chain. Of course this is now the 5th time this vehicle engine will be opened up to diagnose one of the known issues that Mazda north America is aware of. I have had this vehicle since 2007, and has just over 120,000 miles on it. I have maintained a very good service history on the vehicle taking it to "reliable" Mazda dealerships in the area where I live. My main concern is Mazda is doing nothing to rectify the issue and it's only a matter of time before someone is seriously hurt or even worse. The vehicle safety is impaired due to unstable engine performance. There is obvious technical issues with the engines for this Mazda engine model.
