2024 MAZDA CX-90 Complaints

On occasion (several times in a month) I will drive the car listening to the radio. I then park for a short time and turn the car on and drive away when I notice that the radio isn;t on as it was when I parked. I then have to pull over, park the car, shut off the engine then restart. Now the redio comes on. I am concerned that other safety items are also non functioning when this happens. The dealer has been no help.

Can not control steering. Almost ran off the road merging onto the interstate because the steering wheel got stuck.

While driving 35 mph on a busy street, our vehicle completely lost power. The vehicle started violently shaking until I came to a complete stop. Many warning lights came on. Two primary: "Hybrid Malfunction", "Engine Malfunction" along with a couple others. When I stopped the car completely, it took 5 minutes before I could change the car from park to drive to move the car out of the way of oncoming traffic. Sitting in the middle of a busy road with hazards on is not safe!! Also, Suddenly losing power on a very busy street caused car behind me to slam brakes and honk at us. Very lucky we didnt cause an accident. If this had happened in a different situation such as freeway at 75 mph, major intersection, on a long roadtrip etc... the risk for significant disaster increase significantly! The car is current at Tum Dahle Dealership in Murray, Utah. This is the second time in 4 months we've had to take this car to the dealer for an issue. The first time was just an "Engine Malfunction" light. It sure seems like we bought a lemon. Even if they fix this car, my confidence is extremely low in this car being a safe car that im ok with having my family in.

Humming noise coming out of the powertrain that might be related to gear box or bearing. This mechanical safety issues mught endanger my life and cause a breakdown while driving, thus an accident. Mazada did not find the fix yet and unable to repair. Since September 3rd, my car is in Jim Click repair shop with no solution at sight.

The contact owns a 2024 Mazda CX-90. The contact received notification of NHTSA Campaign Number: 25V568000 (Electrical System); however, the part to do the recall repair was not yet available. The local dealer was not contacted. The contact stated that the manufacturer had exceeded a reasonable amount of time for the recall repair. The manufacturer was made aware of the issue. The contact had not experienced a failure.

The hybrid battery and hybrid system malfunctioned. The vehicle emitted a strong rotten-egg odor (consistent with hydrogen sulfide gas) inside the cabin from [XXX] to [XXX]. The hybrid system warning light first appeared on [XXX]. On [XXX], the air conditioner did not work while driving, and on other occasions it failed to turn on until the engine was restarted. On August 5, 2025, the vehicle was serviced for a related recall, but the warning light returned shortly afterward. From [XXX] to [XXX], my children (ages [XXX] and [XXX] ), my elderly mother, and I were exposed to fumes inside the cabin. We experienced headaches, nausea, and dizziness. On one occasion, my mother nearly fainted after dinner while visiting, which coincided with her exposure to the odor. The dealership did not warn me that the hybrid warning light could be associated with the odor or that an odor would be hazardous, so I continued driving the vehicle during this period. On September 3, 2025, the dealership confirmed the hybrid system malfunction, deemed the car unsafe to drive, and ordered a replacement battery. The vehicle was out of service until September 15, 2025, when the entire hybrid battery was replaced. The dealership inspected the vehicle multiple times, and Mazda corporate (Customer Experience Center case manager) was notified. The component was replaced under warranty, but the event created a significant safety risk due to exposure to toxic fumes and the potential for hybrid system failure while driving.

I bought a brand new 2024 CX90 in May 2025. I was on the on-ramp entering a Highway at an accelerating speed when the car all of a sudden went into a limp mode and was unable to accelerate. This limp mode that kicked in almost caused me to be hit from behind. Immediately on the dash it flashed Engine Malfunction. I had to pull over to the side of the highway and had the car brought to my local Mazda Dealer. My local Mazda dealer stated that the recent recall #25V-568 NTSHA caused the program/software for the car to misread my fuel pump and essentially burned out my fuel pump, and therefore breaking my fuel pump. They said they called Mazda, and Mazda is denying the fix because there is "no release date". Since Mazda is refusing to fix this, my local dealer says I have to drive the car as is. However, this is unsafe to drive. I paid for a brand new car only for it to have tech issues with Mazda refusing to do any fixes. This is our family car and I drive around with young kids. This is very unsafe to drive and Mazda needs to remedy this siutation immediately.

My Mazda CX90 consistently has a hard delay before jerking my car forward, especially when shifting between 2nd and 3rd gear. This is most common at slow speeds and accelerating from a stop. On top of generally rough shifting, there have been four separate instances where my car blatantly stopped accelerating and slowed my car from 70-80 mph down to 40-45 mph. Once driving up a hill, and the rest on a flat interstate. I tried flooring the gas each time and the rpms would go up to approx 6000, but the car simply would not respond. After multiple attempts to let off of the gas and re-engage the vehicle, my car suddenly began accelerating again and continued as if nothing happened. I have been able to safely move out of traffic's way each time, but this presents a great threat to myself and others as I have no control over my speed and can easily get into a collision. As if uncontrollable stopping on the freeway isn't enough, my vehicle also accelerates on its own and jolts itself forward when driving at slow speeds through parking lots and stand-still traffic. These accelerations have occurred at idle with the breaks both on and off. The vehicle only propels itself forward by a couple of feet, but the issue seems to be getting more severe each time it occurs. Luckily I have been able to control the car and stop myself from hitting others so far, but I am afraid this may cause harm to pedestrians or people in nearby vehicles. I have mentioned these issues to my local Mazda dealership on multiple occasions, but they dismissed my concerns each time and told me my vehicle is in safe operating conditions. They claim they have not been able to replicate any accelerating/ decelerating instances, and they say the car's shifting is within spec. My car has never thrown any codes or displayed warning lights on the dash. I have taken the vehicle in for all recalls and maintained it well. I recently hit 15000 miles, though these issues have been presenting since 5000.

Steering wheel is "notchy" when turning, mostly to the left. Worse at higher speeds, like exiting or entering the freeway. It often feels like it may get stuck and I have to jerk it to the right a bit to get it unstuck.

Ever since the lease of this vehicle on January 2025 we’ve had problems with the brake/rotors took it in twice for that. As of recent August 2025, we took it in for loss of power going up a hill, hybrid malfunctioning electrical system going out. Dealership gave it back saying everything was fine. We took it on August 29, 2025 to Colorado vehicle failed to perform loss of power going up the mountain almost got hit by a vehicle because I was in a fast lane with my family had to pull over with whatever power I had left in the engine (not the battery). I mean the vehicle just keeps failing to perform as it should as well on the way back. It had the same issues but as severe going to Colorado.Vehicle does not change gears going uphill. When we stopped in Vegas for fuel, fuel door did not open it & malfunctioned. So vehicle does not perform well in cold and hot weather AWD system does not work at all. We feel a jerking, we hear a whistling’s type of noise that the dealership fell to inspect. Per them everything worked fine but when we took it to Colorado this weekend for Labor Day, vehicle underperformed with extreme safety concerns and we contacted Mazda, but they fell to listen to our concerns and say the vehicle is fine but when you drive the vehicle, it does not perform as it should and is a safety hazard to us and anybody around us due to a loss of power and everything I described above.
