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.
