ELECTRICAL SYSTEM, ENGINE
I am reporting serious safety concerns with my Mazda CX-90 PHEV (leased, manufactured September 2023). These issues create unacceptable risk to occupants and other road users. Multiple Severe Recalls: My vehicle has had at least four major recalls: • 6323J – Engine & Motor Shutdown: Complete loss of propulsion without warning. • 7024J – ECU Software Failures: Loss of drive power and restart failures. • 24V817000 – EV Mode Power Loss: Sudden propulsion loss in EV mode. • 6724E – Sudden Braking: Automatic braking without cause. These defects could lead to crashes or fatalities. Hybrid System Malfunctions: Two recent “Hybrid System Malfunction” warnings required dealer visits. These failures could cause the car to shut off while driving—even at highway speeds. • First incident: Battery-related issue. • Second incident: Triggered by a loud noise during startup, impacting the AVAS system. A loud noise should never disable a family vehicle, indicating a design flaw. Charging Safety Issues: Charging via a standard outlet caused flickering lights and breaker buzzing in my house. A licensed electrician diagnosed harmonic distortion from the onboard charger. I spent $7,500 on electrical upgrades (dedicated EV line and panel upgrade) to charge safely. Manufacturer Response: I have had an open case with Mazda corporate for nearly two weeks. They refuse to acknowledge overall vehicle safety or provide written documentation confirming safety. Request: I urge NHTSA to investigate whether these defects represent a systemic safety issue in Mazda CX-90 PHEV models and take appropriate regulatory action

ELECTRICAL SYSTEM, ENGINE, POWER TRAIN
My new Mazda CX-90 failed to restart after being stopped at a stop sign. After restarting manually, the dash displayed the check engine light and the “i-stop malfunction” light. The car now flashes this warning whenever it is on. There is an open recall for this issue (24V-816) but my local Mazda dealer does not pull anything up when they search my VIN. It appears the recall only applies to these vehicles built between 12/23 and 4/24. My car was built in 11/23. I believe this recall should be expanded to included more vehicles like mine.

LATCHES/LOCKS/LINKAGES:DOORS:LATCH, STRUCTURE:BODY:DOOR:HANDLE:EXTERIOR
The exterior rear door handles get stuck in the open position. This is a danger and the door has opened while driving since the door handle did not close all the way. I have tried lubricating the both door handles with no improvement. Our car has never been in accident is approximately 18 months old. I have done research on the internet and it looks like this is not a new problem with multiple owners who have complained to the manufacturer in the past with no fix.

STEERING
Steering "locks up" and the steering wheel is hard to turn back to center when making a left turn. When the vehicle was new and under warrant, I complained to Mazda-USA on 11/21/23 and took it to the dealer and the steering was better afterwards. I assumed they applied grease to something which was Mazda's fix for many other vehicle issues. Now the steering locking issue has returned again and the vehicle is no longer under warranty. I don't feel I should have to pay thousands of dollars to fix their manufacturing defect which came with the new vehicle.

SERVICE BRAKES, UNKNOWN OR OTHER, FORWARD COLLISION AVOIDANCE: AUTOMATIC EMERGENCY BRAKING
I was stopped by a railroad crossing and when I started driving, my automatic emergency braking activated and jerked to a stop. This happened two consecutive days in a row. Gratefully no one was behind me, or they would have rear ended my vehicle.

STEERING
Steering wheel is sticking at highway speeds. When going around a curve at highway speeds, steering becomes stuck, requiring additional effort to turn and keep vehicle centered in lane. Steering wheel has to be 'broken loose' by pulling it to the direction opposite of the curve. This results in the vehicle bouncing around lanes which is unsafe. The vehicle is currently at the dealer being inspected. No warnings were present.

LANE DEPARTURE: ASSIST, STEERING
There is a potential safety risk with the 2024 Mazda CX-90 power steering/lane keep assist. When traveling at moderate speeds steering left into a turn the vehicle jerks to the right. I do not believe this is a direct problem with the lane keep assist as the problem only occurs when in the center of the travel lane and not while on the edge of the road. Lane keep assist works as intended when on the edge of the road or on the center stripped line as I feel a gentle assist again as intended. The hard pulling to the right problem only occurs when steering left into a turn. There are no warning lights on the instrument cluster. The authorized dealer has not been able to reproduce the issue. The issue has been ongoing for at least the past six months.

STEERING
The steering is inconsistent. Sometimes it requires more or less effort to turn. The steering has been sticking around turns lately. This issue started over a year ago. They applied grease and it made the sticking go away but it has came back after 9 months.

STEERING
The steering is notchy during turns when the steering wheel is off center, making fine turning adjustments very difficult especially during turns. If any bumps are encountered during a turn or any turning adjustments need to be made, the steering will catch and release and move in a different direction than expected. It requires constant adjustment but the adjustments are not smooth, there is a binding/notchy feeling. When the car is stationary, the it is clearly observed by turning the wheel slowly and feeling the vibrations or observing the continuous jumps in steering wheel. I took the car into the dealer for repair under warranty and they said the steering wheel turns side to side so it's not a problem and refused to further diagnose or make any repairs. I told them it was unsafe to drive the car as is and they said there was nothing wrong with the car so they wouldn't be doing anything more. I asked to show them what was wrong and they said they had done enough and refused to do any more diagnostics. I asked them to look into Safety Recall 6524A and said it feels a lot like what other people describe was wrong with that recall, they said the recall has already been done to this vehicle it doesn't apply, and furthermore that the recall was not an actual issue but just Mazda wanting stiffer steering feel. I now have an appointment with a different dealer to see if they will fix it since the car feels very dangerous to drive as is.

ELECTRICAL SYSTEM
My 2024 Mazda CX-90 continues to have a malfunctioning fuel gauge despite multiple dealer visits and the recall repair (Recall 25V568). The dealer confirmed the issue was fixed, but it is not. The digital fuel gauge does not update in real time. It remains stuck for long distances and only partially recalibrates after restarting the car. For example, on November 5, 2025, I drove more than 60 miles, but the gauge dropped by only about 10 miles. After turning the ignition off and on, the gauge adjusted slightly but still did not reflect the true fuel level. Photos from that day are attached. I have serious safety concerns. The recall notice states: “If the vehicle incorrectly indicates an inaccurate fuel level, there is a chance of unexpectedly running out of fuel while driving. This would result in an engine stall and vehicle being unable to restart, increasing the risk of a crash.” This issue persists even after the recall service was completed, suggesting that the current fix may not fully resolve the defect. This has been an ongoing issue. I visited the dealership again on Nov 5th, 2025.

ENGINE, FUEL/PROPULSION SYSTEM
Upon starting the vehicle, on the dash there was a message "hybrid system malfunction" as well as "engine malfunction have the vehicle inspected". Upon driving it home, the same message appeared 10/24/25 as of today when the car starts now the only message that remains is "engine malfunction have the vehicle inspected" I have an appointment at Mazda on 10/30/25 for the vehicle to be inspected. This vehicle has already been taken to this location for two recalls. Today 10/26/25 I looked up my vin for any new recalls and there is an additional recall. Manufacturer Recall Number7825I NHTSA Recall Number25V-568 Summary When fuel containing ethanol is used, it may react with materials on the sending unit circuit board in the sub-tank. This reaction can create a buildup that interferes with the gauge function that may cause the display on the instrument cluster to read an incorrect fuel level. Safety Risk If the vehicle incorrectly indicates an inaccurate fuel level, there is a risk of running out of fuel while driving. This would result in an engine stall and the vehicle cannot be restarted, increasing the risk of a crash.

STEERING
The steering rack catastrophically failed at highway speeds with no warning or signals from from the car that anything was wrong. I was driving on a curvy highway at 60mph when the steering started to feel a bit weird when turning to the left. At first it felt like irregularities in the road surface or something of that nature. A few moments later, it was clear that something was completely broken as the car would turn to the right completely normally, but had a wildly different amount of feeling and effort required to turn left at highway speeds. When taking a left curve at highway speeds, the steering inconsistently switched from taking several times more effort to turn the wheel (feeling as if components were grinding together) to being lighter than normal, oscillating back and forth between these feelings randomly. I distinctly remember that recall 6524A and the associated stop sale was for "2024 Mazda CX-90 vehicles that have a sudden increase in steering effort while driving" due to "A worm gear in the steering gear assembly may have excessive friction, leading to a sudden increase in the effort required to turn the steering wheel while driving" which said that "This sudden change in steering effort could increase the risk of a crash". I'm suspicious that the failure that I experienced is related to this original issue despite the recall being "resolved" for my 2024 CX-90. I can say with certainty that I'm lucky that I did not crash due to the issue. I'm extremely concerned that this failure poses an imminent safety risk for drivers in other CX-90s. I'm also concerned that Mazda created a new steering rack for later model years unaffected by recall 6524A and provided an ineffective fix to the original problem.

VEHICLE SPEED CONTROL
On or about [XXX], I leased a 2025 Mazda CX-90 PHEV Premium Sport from Bob Penkhus Mazda, Colorado Springs, CO. Within approximately six weeks, on [XXX], while traveling south on [XXX] from Pueblo toward Walsenburg, the vehicle experienced severe loss of power under load. Despite the accelerator being fully depressed, the vehicle would not exceed 74 mph on the initial incline and later would not accelerate past 64 mph near La Veta Pass, even in sport mode. During an attempt to pass a slow-moving truck, the vehicle failed to accelerate, forcing me to brake hard to avoid a head-on collision. My fiancée and our infant twins were in the vehicle at the time. I immediately contacted Service Manager Steven Constable at Bob Penkhus Mazda. The dealership retained the vehicle for inspection but claimed they “could not duplicate” the issue because “they don’t have mountains to drive it up.” No repairs were made. Instead, I was told to “drive it for 30 days to monitor,” despite the documented safety risk. I refused to assume that risk and requested a repurchase, replacement, or trade into a non-PHEV model. I even offered to accept a lower-trim base model, provided it had captain’s chairs, and to continue paying my current monthly amount. The dealership and General Manager A.J. Ager rejected this and demanded that I personally pick up the unrepaired vehicle, although they knew I live three hours away in Monte Vista and Mazda advertises complimentary pickup service.

TIRES
The tires are listed with the manufacturer and were sold by Mazda on a brand new car to me as 65,000 mile tires I was at a little over 17,000 when Mazda said they were “wearing” oddly and this past Monday they said I needed replacement tires. The pros at the dealership stated they are seeing all CX-90 and CX-70 hybrids need tires before 25,000 miles. It is all over the internet that people are being told the extra weight and torque from the motor are wearing tires to quickly leading to needing to replace them well before time and or some folks are having tire failures. The couple at 16,000 miles needing tires was horrible to watch. It is my belief that the issue is a Mazda and falken failure due to a tire being used that is not suitable for the performance for the vehicle leading to a failure in safety. The dealership also stated the mileage had been removed from the tire sheet by Mazda for this particular tire in the last couple weeks so consumers can no longer request the printout for the VIN of their vehicle, but the mileage still remains for CX-5 options at 65,000. Mazda knows it is an issue and needs to find a solution quickly before lives are lost.

ELECTRICAL SYSTEM, UNKNOWN OR OTHER
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.
