The 2024 Mazda CX-90 is a larger crossover SUV with three rows of seats for larger families. It’s the second model to use the Mazda RWD and AWD platform with the longitudinal engine configuration, such as the CX-60. This model replaces the CX-9 in America and there aren’t any sales figures on it yet.

Most Common Problems with the Mazda CX-90

As a brand-new model, it’s expected that the 2024 Mazda CX-90 would have some issues. However, customers weren’t prepared to deal with the long list of problems coming out of this new Mazda SUV. It deals heavily with issues in the electrical system, powertrain and interior space (NHTSA).

Problems with the Electrical System

  • Carbon monoxide alarms: One owners had the CX-90 parked in the house garage overnight and woke up to a carbon monoxide detector going off. When entering the garage, it was clear that the vehicle was hot to the touch and it smelled like something was burning. The vehicle also wouldn’t start again after that incident.
  • Possible electrical issue: Customers have complained that the Mazda hybrid can often smell like it’s burning. The concern is that it could have spontaneous combustion, especially while sitting inside somebody’s garage.
  • Malfunctioning blind side detector: As part of the safety system, the blind spot warning is supposed to tell drivers when there’s another car in an area that’s hard to see. However, the blind side detector randomly illuminates even when there’s no other vehicle nearby. This causes drivers to spend an excessive amount of time looking for something that’s not there, leading to distractions and possible accidents.
  • Glitchy wireless charging pad: The wireless charging pad is sensitive. If the phone isn’t placed on it just right, the device isn’t going to charge normally.

Powertrain Issues

  • Vehicle loses speed: Drivers struggle with the vehicles losing speed while adaptive cruise control is enabled. For some, depressing the accelerator pedal with this system engaged doesn’t change anything. The car still doesn’t increase speed. While this is occurring, a message displays on the car telling drivers to shift into Park to use the accelerator pedal. However, that requires first stopping the vehicle in a safe location, which isn’t always easy to do, especially while driving down a busy highway.
  • Excessive engine noise: Owners of the PHEV have complained about an extreme amount of engine noise while driving. The other variant doesn’t seem to struggle with this as much.
  • Jittery movements: Hybrid CX-90 owners have complained about how the powertrain feels jittery and unstable. After the vehicle is running for a short time, the problem seems to resolve itself, but it’s still unnerving in the beginning.

Interior Problems

  • Firm seats: The seats in the CX-90 appear to be too firm for more drivers. While firm seats might be a good quality for a sports car, it’s not desirable in a family SUV. For customers looking for a more comfortable ride, an older CX-9 provided more support.
  • Small third row: For being a family-friendly SUV, owners find the third row to be extremely small when equipped with the second-row captain’s chairs. It appears that the center console in the second row is what creates the tight space, so it might be slightly better with the bench seat in the second row.

    Just Purchased a New CX-90…My 5th Mazda and my God is this thing Garbage! I couldn’t leave the Dealership because they had to Reboot the Windshield Wiper.(the passenger side was going severely fast and out of Sync. The 2 Captains Chairs in back Severely Shake when going over 50. The FM Radio will not Work for about 5 Minutes. Severe Scratches on ALL Plastic Molding above Wheels. And the Engine makes Funny Noises. Utterly Disgusted with the Quality of this Vehicle!
