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) to my fuel pump. Unless Mazda stole my car and returned it no work was ever done on my fuel pump. Only oil changes. Could an upgrade NOT performed and my Vin was marked as upgraded but wasn't" Why do I have a faulty fuel pump withBthe EXACT symptoms on the EXACT model or EXACT year of my Mazda.. NO ONE at Mazda will tell me what brand fuel pump was manufactured in my car. Neither the dealerships or the 800# I call can saY what fuel pump was manufactured in my car. But they can say what was recalled based on vin#. The car just turned 5 years old and shouldn't need a new fuel pump. Isn't this all a little suspicious especially since they cannot conveniently for them say what manufacturer fuel pump is in my car. The car has lost all power and stalls. What happens when I pay the $1600 and the fuel pump is the Denso that is faulty. What then" No one will help. All of this is fishy as can be especially cause I own the EXACT YEAR BRAND AND MODEL WITH THE EXACT PROBLEM THE OTHERS WERE RECALLED FOR. Please say to yourself this is a little fishy and ask questions instead of going by a computer. As a human being look at this as highly coincidental and needs looking into instead of dismissing me.

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) I told him its not cruse control. He then said that's how it was design. I believe it's is a safety hazard. Thank you for your time.

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.
