The radio changes stations by itself, speakers/music goes in and out. The screen freezes and cannot change stations. And also the car lags on taking off sometimes. Often smells like fuel when you turn on the car, Assuming a fuel pump issue, not sure. I spoke to the salesman who sold me the car (adam) within less than 30 days of having the vehicle and told me the electrical issue with radio would be covered. Then when I called to have the issue fixed I was told it wasnt going to fixed on their behalf. This car was sold to me with a few issue that I was not aware at the time of purchase.

This car that I financed on [XXX] 2024 has been back to the dealership over 6 times. My car loses power on the freeway and all main roads. I push the gas pedal and nothing happens so I am forced to pull over and turn the car off and restart it again. It's very dangerous when I'm merging on the freeway and I cannot accelerate and have to pull over in traffic. Sports cars International in Lynnwood Washington is well aware of the issues I've been having and they have not fixed them. They have allowed me to drive off the lot knowing I am in a car that is dangerous and unsafe, a car that could kill another family or myself. They are unresponsive to call of my phone calls and emails. This car has had nothing but problems since then day I drove it of the lot. Come to find out from their Yelp and BBB reviews thus happens to a lot of people that buy cars from them. They are rude to me and I feel like I'm on danger every time I drive this car.

Despite a recall on the fuel pump, there continues to be a problem but instead of the “back” fuel pump that was fixed, the “front” fuel pump seems to be having the same issue. When taken to the dealer, the code P0087- fuel rail/system pressure too low shows up. This is causing car to stall, unable to pick up speed or simply pick up too much speed when attempting to accelerate. It’s a safety hazard for a car less than 6 years old.

This vehicle has stalled out while driving at least 4-5 times since purchasing it in 2018, although issues started about 2020 or 2021. It usually starts with the radio console either malfunctioning or going dead completely while I’m driving and several minutes later (usually after stopping at a red light but sometimes while actively driving) the car stalls out in the middle of traffic. It starts up after few minutes but it’s a very dangerous situation. It also sometimes hesitates when putting my foot on the gas, as if there’s a fuel injection problem. I already got all the recalls fixed but there’s obviously other significant problems with this vehicle. If it causes me to get injured I will be taking legal action.

Fuel pump. The mechanics at the Mazda dealership brushed me off when I brought up the open recall on my vehicle. However, according to them it is a "preliminary recall," the mechanic said it wasn't an "open recall." This is my first vehicle and I stupidly put my trust into the mechanic and believed his words. I am not well-versed in vehicles but after extensive research, asking a friend, and referring to a VPC agent who deals with recalls on vehicles; it turns out there is no such thing as a preliminary recall outside of Mazda's definition. I told the mechanic it was an open recall and that I need to ship the vehicle to Hawaii and the shipping company can refuse service if there is an open recall. The mechanic still brushed me off and talked to me as if I was dumb because I couldn't understand what he was saying. He continued to say they don't have the parts regardless and said "no one does." I didn't press the issue because I assumed they knew better than I. It seems as if Mazda is refusing to work on, look at, or even hear about the fuel pump recall.

Follow up! I originally posted I thought this was an engine issue. However, after reading about the huge recall with Mazda due to a faulty Denso fuel pump I quickly realized this is 100% issue. This causes my car to stall on the highway and stop accelerating at 65mph. Huge safety issue! Many other car dealers have been hit with too. However, my VIN is not part of the recall. There are claims on court docs there are more vehicles part of this recall than what Mazda is owning up to. I find it hard to believe I am the only one. Mazda pony up and do the right thing for your consumers.
