On-going issues with gas pump shutting off at pump. Took car to get it check. Back and forth with dealer to fine issue for over several months period. Engine warning light came on twice. Customer request dealer to check fuel systems. Gas leak discovered, along with clogged fuel vapor lines. Spider webs near fuel lines. Customer suspect fuel system defect. Dealer suggest fuel system replacement. Since out of warranty, customer reach out to manufacturer.
Check engine light came on shortly after I purchased my brand new mazda cx7. Dealership just simply resetted it without further inspection and now after warranty light is back on. Had already replaced gas cap and l reset was done again but it is back on. I read a lot of complaints online about the check egine light. I seems like a common problem with mazda cars but mazda does not seem to concerned about it. My car cant pass inspection because code p0442-evaporative emission system leak detected (small leak) keeps coming up. I want mazda to correct this problem because it appears to be a common problem among mazda owners. Emailed mazda and no answer so I called 800 number and was told that there are no recalls on this problem. Please help. Not sure of the date it initially happened. But check engine light came on again last summer 2018 thanks.

I am having issues with my engine light on and my car having problems with a loud noise coming from the engine as well as sometimes shaking while stop in a light for a while.
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?
