Hybrid battery recall was replaced and failed a month later for a second time burning other systems and causing a compete failure in the car. It failed in a deserted portion of [XXX] while traveling from [XXX] to [XXX] for important business. This left me stranded in the middle of the [XXX] desert late at night in a dangerous area. It failed on the highway loosing complete power with multiple failures reported on dashboard. I was left stranded in the middle of nowhere with no nearby services or immediate assistance and was forced to remain in the vehicle overnight in unsafe conditions. The vehicle required towing, and I was later informed the issue was again the hybrid battery the same component that had already been replaced under recall less than one month prior. This repeated failure creates a serious safety concern because the vehicle can unexpectedly lose power and leave occupants stranded without warning, even in remote or unsafe locations. In addition it lost power on the highway and that posses a significant safety concern. The vehicle is unreliable given its age and repeated failures, and I am requesting investigation into a potential safety defect involving the hybrid battery system and sudden loss of propulsion/power and damages to other parts. I had 8 different warnings on my dashboard before the car completely died and I couldn’t even open or close windows or lock and unlock doors.

So, if the car is on electric and I press on break, sometimes breaks feels like it's delayed to response. The car will switch to gas after it and the break will work. This happened to me in the 2024 and 2025 CX90 PHEV version. I had that issue multiple times.

Every time I drive the vehicle, it basically snatches me back into the lane aggressively. If I am moving into the next lane, the lane correction is so aggressively, I am afraid it is going to cause a collision. The brakes squeak and squeal constantly. They have oiled the brakes but it didn't work.

Seatbelt got stuck between seat and seat frame. Seatbelt was stuck in the locked position and was neither able to be retracted or pulled out rendering the seatbelt unusable. This is a huge safety concern as we were stranded at night with small children and unable to use the seatbelt. A recall should be made to this vehicle (Mazda cx90). Further Mazda is claiming that seatbelts are not part of the warranty (it’s a <1 year old car) and they are charging $1000 to fix this. This is a huge safety issue to not have a functioning seatbelt and a design flaw that should be fixed. It is too easy under normal use for this to occur.

Following a period of heavy rainfall, I entered my vehicle and began to drive off when an excessive amount of water suddenly poured into the cabin from the overhead console (where the light and sunroof switches are located). ​To investigate the source of the leak, I opened the sunshade but found no residual water or permanent staining inside. Moving to the exterior, I verified that the sunroof was fully sealed, but I did notice an unusual gap/channel gutter between the top of the windshield and the roofline. ​I took the vehicle to the dealership the following day. While there, I learned that another 2026 CX-90 was brought in at the exact same time for the identical issue. The dealership's technician inspected my vehicle and found that the flap at the bottom of the sunroof drain was stuck. They cleared the debris, verified proper water flow, and cleaned the drains from the roof down as a precaution. They also advised me to avoid parking under trees. ​Because this is an internal gutter system, a simple clog shouldn't result in immediate, severe cabin flooding over critical electronics. This is a serious safety hazard and a design flaw. Left unaddressed, this issue poses a severe risk for electrical shorts, potential vehicle fires, and toxic mold development. This design vulnerability needs to be formally addressed by the manufacturer.

Vehicle cabin air vents blow air that is over 101 degrees Fahrenheit with the air conditioning system turned off and the blower turned on. Cabin temperature was set to “lo” and outside ambient temperature was 55 degrees Fahrenheit. This is a safety hazard as the vehicle should not blow extremely hot air in the cabin and cook its occupants.
