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?

My mazda cx7 - 2008 has only 70,000 miles and the engine light went on 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.

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.

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.

So this is my complaint and story so we went to florida like a week and came back to texas. When we got back home I started to hear an noise on the engine. I took the car to the mechanic and he said that wasn't normal it sounded like a diesel truck. So the next day I had to go to work and I was coming back home the engine light started to flash continuously and car started to shake so I drove it to a auto parts store, so they can check the code and they said it was a piston 3 misfire. I took it to mechanic again and he said the spark plug had oil and he said that was not a good sign he said it might be the engine or a bent valve. First of all this is our only car and don't have money to fix it. A use engine cost 3,000 and up and if its the head it cost like 1900 and I've been reading a lot of bad reviews of this car I really need help I can't afford to fix my car we are a family of 5.

While traveling at 45mph, experienced sudden loss of power. Cel came on and trouble p3001 was the code display on handheld reader. Car is out of warranty, dealer states several components within engine have failed and mazda has no responsibility over failures since I do not have an extended warranty. I have researched the problem production years 2007 and 2008 are plagued with premature engine failure.

Check engine light came on took it to dealer...egr value needed to be replaced...warranty was expired. About $700 or part...wondering if there is recall on part. Reading forum and seems to be a problem with others.

The vehicle is a 2008 mazda cx-7 bought as a pre-owned certified from mazda dealer in ramsey, nj. It had the engine light on and I took it immediately to the dealer near my work (colmar, pa) and it was diagnosed with code p0401, egr valve failure. With under 40k I was not expecting this to fail and the repair cost was $718. (diagnosis, parts and labor). I looked up online and saw that it is a frequent issue with people having much newer car than mine. Obviously it was not covered under warranty and I had to pay from my pocket. But I am disappointed with the repair as the next day the brake light came on. It comes on in the morning and stays on intermittently. It finally goes away after 15-20 minutes of driving. I plan to go to the dealer tomorrow to see if this is something that resulted during yesterday's repair.

On my way to work I glanced in my rearview mirror and noticed white smoke coming out from behind my car. I looked at my gauges and noticed that my battery light was on and my temperature gauge was all the way on hot. Pulled to the side of the road and, as I pulled over my engine light came on and my power steering went out. I shut off the car and called my husband (who owns a collision repair shop and a tow truck) and told him to come and get me and my disabled car. As I sat in my car waiting, a police officer came to check that I was o.k. The officer sat in his car behind me for about 10 minutes and then backed out and left. Within a few minutes of the officer leaving a gentleman and his wife pulled over a good way up in front of my car. The gentleman got out of his car and started running to me shouting get out, get out, your car is on fire!? The gentleman called 911 to summon the fire department. As we waited for the fire department a highway patrol assistance vehicle pulled over because they had a fire extinguisher. My husband arrived and took the car back to his place of business. Our insurance was company was called and they sent a claims adjuster out to assess the damage. Our claims adjuster determined that the fire had started with the air conditioner and had caused $3,900.00 in damage to the mechanicals of the car.
