ENGINE, SUSPENSION, POWER TRAIN
After driving >2000 miles or about a month, I could hear a loud, grunting/grinding noise when accelerating aggressively from 1st to 2nd gear when on EV or gas mode. Brought the vehicle at the dealership service department 4 times already, each time MAZDA Headquarters in California confirmed that this is a known and documented condition. According to Mazda, the grunt noise you’re hearing when the vehicle shifts from first to second gear under medium to aggressive throttle is considered normal operation. It has been determined that this does not affect the drivability or reliability of the vehicle, and it is safe to drive. The transmission is operating as designed and performing within normal parameters. Mazda is continuing to collect data on this condition as part of their ongoing commitment to improvement. However, I totally disagreed to their answer and that the truth is that they don't know how to fix it, unless tearing down completely the transmission to find out what the cause is! I feel it is a safety problem as explained by a top transmission repair shop: "In most cases, a loud, grunting or grinding noise when accelerating from 1st to 2nd gear would likely be considered a defect that substantially impairs the vehicle's use and could also affect safety, particularly under the context of Oregon's Lemon Law. Here's why: •Impact on Use: Grinding and grunting noises suggest that the transmission is not functioning properly, according to Top Notch Transmissions. This makes the vehicle less reliable and less enjoyable to drive. If the problem persists or worsens, it can hinder the vehicle's ability to operate safely and effectively, potentially leading to hard or delayed shifting, or even transmission failure."

ENGINE, POWER TRAIN
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.

SERVICE BRAKES, FORWARD COLLISION AVOIDANCE: AUTOMATIC EMERGENCY BRAKING
The car automatically brakes at lower speeds. This happens about 3x week and typically on a specific freeway entrances but in other locations as well. I believe this is a known phantom braking issue but for some reason my car is not included in the recall.

ELECTRICAL SYSTEM, UNKNOWN OR OTHER
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.

VEHICLE SPEED CONTROL
The drive power on my 2025 Mazda CX-90 was SEVERELY reduced last week while making a left turn in front of oncoming traffic. No warning light nor sound from my car appeared at the time of this incident. The vehicle was purchased 5 months ago and there have been other occasions where the power was reduced while turning. This incident, however, was the most dangerous. The turn was made at a traffic light while sitting on a hill yielding to oncoming traffic. The approaching car was moving slow enough to make a safe left turn in front of it, but the lack of power prevented me from making a reasonable (not reckless) fast turn. Fortunately the oncoming vehicle was able to stop in time to prevent an accident.

FUEL/PROPULSION SYSTEM, ENGINE
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.

POWER TRAIN, ENGINE
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
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.

LANE DEPARTURE: ASSIST, FORWARD COLLISION AVOIDANCE: ADAPTIVE CRUISE CONTROL, LANE DEPARTURE: WARNING
The Mazda CX90 PHEVs i-activesense system that controls the adaptive cruise, lane departure and lane keep assist system disables at random times with a message "i-activesense temporarily disabled. front radar obstructed." There is never any objects obstructing the radars and no outside weather/elements affecting it. It will not turn back on either, even though it should turn back on if the obstruction is cleared from the radars/sensors. Since there isnt anything to clear when it happens, it stays disabled unless the vehicle is turned off completely and back on. I have had this vehicle for 2 weeks and it has disabled on the interstate traveling 70+ mph and on city roads in congested traffic over 15 times. When it happens with the cruise control enabled, it immediately begins decelerating quickly, causing a safety issue when on the interstate at high speeds. Was brought back to service 24 hours after acquiring the vehicle but Mazda cannot seem to figure out what is wrong with it. Its a huge safety issue when it all disables and the car quickly decelerates without any warning. Has happened on multiple dates, at least 15 times in 2 weeks, at various speeds with 75 mph being the fastest.

ENGINE, ELECTRICAL SYSTEM, VEHICLE SPEED CONTROL
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.

STEERING, ELECTRICAL SYSTEM
"The steering wheel intermittently sticks and feels resistant when switching lanes or making turns, especially at highway speeds. It does not return smoothly to center, making it feel unsafe and unpredictable. I brought the vehicle to the Mazda dealership, but they stated they 'cannot replicate the issue' and refused to perform any repairs. This is a safety concern because the sticky steering can make it difficult to control the vehicle and could potentially lead to a crash. There are no warning lights or error messages displayed when this occurs. The issue happens intermittently, making it hard to demonstrate on demand, but it is recurring and worsening. Since this is a brand-new 2024 Mazda CX-90, I believe this could indicate a defect in the electric power steering system or related components."

BACK OVER PREVENTION: WARNINGS, BACK OVER PREVENTION: SENSING SYSTEM: CAMERA
The backup camera did not beep as I backed into a mailbox. The emergency braking also did not activate. The following day when I used the backup camera it was displaying an image of somewhere I had parked prior (it was not the real time image). The wrong image stayed displayed despite turning the car off and back on multiple times.

TIRES:TREAD/BELT
While I understand that tires themselves are typically covered by the tire manufacturer’s warranty, this situation is different. Mazda equipped the CX-90 with Falken OEM tires that are inadequate for the weight and design of the vehicle, leading to premature wear at only 20,000 miles. This is not normal wear-and-tear. My claim is that Mazda bears responsibility for installing unsuitable tires on a heavy SUV, which created a safety hazard.

VEHICLE SPEED CONTROL, FUEL/PROPULSION SYSTEM
Decelerating behind traffic my Mazda cx90 shut the engine down. While still rolling traffic began to accelerate and I pressed the accelerator. The engine did not restart. I bottomed out the pedal with no reaction. I completely removed pressure from the pedal then pressed again before the engine restarted. This vehicle has already had a recall repair that seemed to be for this issue

STRUCTURE:BODY
The rear door seals on the vehicle do not seal which allows water and dust to enter the vehicle from the rear two doors. Mazda customer service has been contacted multiple times on this issue and they refuse to address the issue. The dealer it was purchased at said it was a known issue after we had already purchased the vehicle. You can look online and see a bunch of people reporting the same issue with no resolution.

ELECTRICAL SYSTEM, ENGINE
On two separate occasions, my young children were locked inside the vehicle, and on one of the two occasions my elderly mother was also locked inside. In all incidents, the doors and windows remained closed and would not unlock, even when attempting to use the key fob. Specifically, after parking, I exited the driver’s seat and closed my door. When I went to open the rear doors to get my children out of their car seats, the rear doors were locked and could not be unlocked by the key fob. The same occurred when my elderly mother was in the vehicle. Each time, the car was in hot conditions, and we were fortunately able — after some struggle — to unlock the doors and remove them from the vehicle. This presents a serious safety risk, particularly in warm weather and with young or elderly passengers who cannot exit the vehicle themselves. I am currently pursuing a lemon law claim for this vehicle, but I also wanted to formally report this defect because of the danger it poses.

HYBRID PROPULSION SYSTEM
The contact owns a 2024 Mazda CX-90. The contact stated that the vehicle failed to start up after several attempts due to an issue with the hybrid battery. The contact stated that the message "Electrical Leakage in the Hybrid System” was displayed. Due to the failure, the vehicle was towed to a dealer where the service technician acknowledged that the failure and confirmed that the issue with the hybrid battery was a known issue. The vehicle was not diagnosed or repaired and remained with the dealer. The manufacturer was not notified of the failure. The failure mileage was approximately 24,000.
