2018 MAZDA MAZDA3 Fuelpropulsion System Problems

I was parked in a downtown garage, and the vehicle would not start after many attempts, after about 45 minutes of trying (waiting 5 minutes between tries). The engine would turn normally and sounded like it was trying to start, but didn't fully engage. It finally did after 45 mins, and I drove it to the local Mazda dealer in Honolulu. I noticed the check-engine light was on at that time (but not before the incident). They ran a diagnosis, and couldn't replicate the issue, and said it may be a battery problem with low voltage, due to the engine's error codes. But I questioned that since the engine was able to turn normally and adequately at all starting attempts. And the battery was only 2 years old. So I replaced the battery at their recommendation. About 2 hours after picking up the car from the dealer, the same issue...

The car just didn't want to turn on with the key and completely stopped

Fuel smell after a fill-up, fuel pump is cracked/deformed EXACTLY as described in Mazda bulletin 5321K (THIS BULLETIN EXCLUDES THIS MODEL). Strong fuel smell in the cabin, liquid fuel leaking from the top of the tank.

I have a 2018 Mazda 3 hatchback 2.5l with a faulty fuel pump. I bought the car 1 year old with 2k mikes on it in 2019 from Jake Sweeney Mazda in Cincinnati ohio. They tell me the issue with power loss and stalling I need a new fuel pump it's failing cost is $1600 to repair. Then I learn a few days later on my own 121,000 2018-2109 Mazda 3 and others were recalled due to a faulty fuel pump with the exact problem I have manufactured by Denso. But I'm told my vin # isn't on the recall. The Denso fuel pump is the brand. However no one at the dealership in Cincinnati or Columbus ohio will tell me what type of fuel pump I have. When I went to the Columbus dealership I believe called Byer Mazda they told me an upgrade was done (which never happened)...

I was driving my car and it suddenly jerks a few times and the engine light turns on. i slowed down and then began to accelerate, and it was losing power and wouldn’t t go above 40mph - even while flooring the gas pedal. Now it won’t start at all. the lights turn on and everything else is fine, but car won’t start and after checking CEL, i’m getting the code p0192 indicating it’s Fuel Rail Pressure Sensor Low Input.

PLEASE HELP ME I HAD PURCHASED A VEHICLE FROM OURISMAN MAZDA IN LAUREL MD. EVER SINCE I PURCHASED IT I HAD AN ACCELERATION PROBLEM THEY HAD TOLD ME THAT AS LONG AS THE ENGINE LIGHT DOESN'T COME ON ITS HOW IT WAS DESIGN. WELL IT KEEPS THE SAME SPEED AND RPM WHEN YOU LET OFF THE ACCELERATOR. I GUESS YOUR AGENCY HAS CONTACTED MAZDAUSA FROM MY LAST EMAIL. THIS TIME THEY TOLD ME THAT I HAD PURCHASED A 2016 AND ALL ABOUT THE WARRANTY. I HAD PURCHASED A 2018 MAZDA 3 SPORT SEDAN. VIN : (XXXX). I HAD BEEN TOLD BY A MECHANIC THAT WORKED AT A DEALER THAT THEY HAD OTHER COMPLAINTS OF THIS PROBLEM. WHEN I TOOK MY CAR TO THE DEALER I HAD LET THE LEAD MECHANIC DRIVE MY CAR AND HE SAID LOOK IT KEEPS THE SAME SPEED (AFTER HE TOOK HIS FOOT OF THE ACCELERATOR)...

WHEN I LET OFF OF THE ACCELERATOR IT STILL MAINTAINS THE SPEED IT WAS GOING BEFORE I LET OFF THE ACCELERATOR. THE DEALER TOLD ME THAT'S HOW ITS DESIGN. HE EVEN TOOK IT FOR A RIDE AND SAID SEE IT STILL KEEPS THE SPEED I SAID ITS NOT CRUISE CONTROL. I HAD CONTACTED THE DEALER AND MAZDAUSA. MAZDAUSA IGNORES ME. I JUST NEED TO GET THIS FIXED BEFORE SOMEONE GETS HURT. WHEN I GO TO PASS IT STAYS FOR A WHILE AT THE SPEED I HIT BEFORE I RELEASE THE ACCELERATOR.
