general problems of the 2008 Mazda CX-7

I was driving down the highway and suddenly I hear a loud noise sounded like I was in a big rig truck then all of a sudden it started to overheat b4 I could pull off of highway it cut off right in the highway I had my grandson with me and thank goodness there was not a lot of traffic or we probably would've been dead.

I already have a complaint but I forgot to add that my airbag light is on and won't come off along with my engine light it won't even crank since we broke down in the middle of highway because idh the money to get it fixed and trying to ask for a ride everyday! thank you so much.

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.

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.

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.

This Mazda Cx-7 is at a Mazda dealer's service center right now getting the timing chain replaced, vvt issue corrected, a new turbo system to keep it from dumping tons of blue smoke from the exhaust, a/c system fixed, and there is an intermittent electrical issue as well. Not happy obviously, as these are all know issues with the vehicle. Mazda has agreed to pay for the timing chain, but the rest comes out of my pocket.

We bought this car on February 19, 2011 with around 26,000 miles on it. On January 30, 2012 (around 36,000 miles) the engine light came on and the vehicle lost all power. We took it to our mechanic to have it diagnosed and it came back that the mass air flow sensor was bad. We had that replaced, but it made no difference at all. The engine light came back on and that mechanic told us we would have to take it to a Mazda dealer and that if it was anything to do with the powertrain, it should still be under warranty. We were happy to hear that indeed it was still under warranty and that Mazda most likely would cover all costs. A day later the dealership called to tell us that Mazda needed to see proof of maintenance on the oil changes, as there was a "sludge buildup. " we had the oil changed as required, but were told that Mazda may not honor the warranty after all. . . Seems it doesn't matter if you did everything right or not, Mazda seems to be denying this is a major problem. We are still waiting to hear if this will be covered, and have been doing lots of research on this issue. We wanted to get a start on this issue if it ends up being the nightmare that other owners are describing. There seems to be a major engineering flaw and we are afraid of losing everything due to the extreme repair costs associated with this problem. Not to mention recurring issues that seem to arise after the repairs are made! Mazda needs to stop the denial and resolve this issue ASAP! hopefully you can please help some hard working people who cannot afford these costs! thanks for your time. . .
