Other Fuel System problem #1

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.

Other Fuel System problem #2

I was driving at a normal rate of speed on a fairly busy street when the car just suddenly decelerated, causing the car behind me to swerve to narrowly avoid me. Thankfully he also avoided hitting anyone else. My car continued to move forward, but with no ability to accelerate. I managed to get clear of traffic and was able to get the car to a repair place nearby. I was told that the entire throttle body was bad, and that it would have to be replaced. The car is a 2011, less than 60k miles on it with regular oil changes and has never had any issues until this. The complete and immediate deceleration seems quite dangerous in my opinion. And having done some reading online, this seems to be a fairly common problem that Mazda is aware of yet has done nothing to rectify.

Other Fuel System problem #3

From the day I purchased my cx7 the brakes were not working properly and the air conditioner made loud banging noises and does not get cold. When I was at my wits end and took cx7 to dealer at 9,600 miles Mazda said I had a bad master cylinder and replaced it. When the master cylinder was replaced my check engine light came on. Mazda ordered another master cylinder and a brake booster. When these were replaced my check engine light came on again. Mazda said my engine was running on a lean mixture and corrected this. The check engine light is off cx7 runs very roughly. Only use premium gasoline and synthetic motor oil. Mazda field representative advised me and dealer that loud noise from air conditioner is normal and typical of all similar Mazda vehicles. I have this documentation regarding a/c in writing from Mazda. Air conditioner barley gets car cool, is ineffective when temperature is ninety degrees. My brakes are slightly better, but still low and soft. Cx7 runs extremely rough and is getting very poor gas mileage.
