    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…

    The cylinder head on my 2018 Mazda CX-5 developed cracks on the exhaust side, leading to significant oil leakage onto the exhaust manifold. This has caused engine damage and safety concerns. The vehicle is currently at a Mazda dealership, where the issue has been inspected and documented. The component is available for further inspection upon request. The oil leaking onto the exhaust manifold creates a serious fire hazard due to the high heat generated in this area.…

    My 2018 Mazda CX-5 Touring has been experiencing problems with the multimedia display for over a year now. At random times the multimedia display cycle through all the menu options (radio stations, navigation, maintenance system, etc) on its own. Makes unwanted phone calls, changes radio settings, attempts to reset maintenance reminders and computer settings. We don't know what is it is trying to do behind the scenes. This represents a risk while driving and needs to be a…

    While driving through town the braking system malfunctioned and the car came to a stop in the middle of the road with messages on dash saying the smart city braking support was malfunctioning as well as brake assist. Engine light came on as well as traction control light right after the car coming to a sudden hard braking stop. Drove straight to shop to check engine code which was p0882. I am so afraid of this happening on the highway with my daughter in the car. There is a…

    The infotainment center glitches and starts clicking things on its own, often changing the volume to all the way loud suddenly orchanging radio station constantly, startling me while I am driving and causing major distraction which can easily lead to an accident. Settings, including safety setting start to get changed on their own while driving as well. The edges of the screen on the infotainment center are also crackling on their own inside the screen somehow, and I am not…

    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…

    For the past year my car has been in and out of the Mazda dealership. There is a red key with an explanation point through it that was been coming up once I am in the car and someone else opens a door then it stays flashing the whole time I'm driving. My trunk has been having issues too with not opening like it should and when I'm driving then I go to turn it starts beeping. The dealership keeps telling me they can't replicate the problems and keep giving me the car back. I…

    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…
