2025 Mazda CX-90 Owner Complaints

The tires on my 2025 CX90 where declared by the dealership to be unsafe/worn at only 20,000 miles. They told me the tires are well into the red zone for replacement. The problem was confirmed by the dealer where I brought the car. The tires are Toyo open country. Evidently Mazda issued a TSB for the Falkan tires that are also failing early. Mazda and the tire manufacturer are well aware of the problem. They have offered to give me 50% off a new set (not to include mounting, balancing, etc.) of the same tires which will only wear out quickly like the current set. The challenge is neither the dearlership or Mazda will help with purchasing other tires that will wear longer and since there are so few tires that will fit the CX90 I feel my concerns are not being addressed. I do not want to buy another set of faulty tires - the internet is full of consumers discussing this very issue.11

At roughly 15,000 miles, the OEM Falken tires experienced severe, premature tread degradation down to the cords under regular driving conditions. Mazda is aware of the defect, as documented in TSB 02-003/26 regarding higher-than-expected wear rates on these factory tires. Driving a 5,000-lb SUV with compromised tire integrity presents a severe safety hazard, including catastrophic highway blowout and loss of control. Mazda has avoided a formal safety recall by classifying the repair as limited 'goodwill assistance' while denying warranty reimbursement to affected owners. This widespread tire defect on heavy vehicles warrants immediate regulatory investigation.

275/45R21 Falken ZIEX ct60a A/S Hi, Yesterday I went to my Mazda dealership to get an oil change and was to told my tires are at 4/32 backs 6/32 fronts Falken ZIEX ct60a A/S 275/45R21 I bought my 2025 Mazda CX90 PHEV on 8/1/25 and has 13020 as of today. They told me Mazda and Falken have a settlement agreement and know the tires are faulty BUT wont replace for free till 3/32.. I told them I don't feel safe driving on these tires and Falken acknowledge the tires have an issue they should be replaced before our Wisconsin harsh winters.. BUT they wont till the trend goes to 3/32. The dealership wants me to replace these tires now as we have harsh Wisconsin winters and these tires wont be safe to drive on for the upcoming winter and because the CX90 is so heavy they don't think with this trend it would have stopping issues on these tires.. I've never heard of tires going so bad so fast. Can you please help.. Thank you

I was driving on the freeway at about 60mph with my family in the car (kids in backseat). The sunroof spontaneously exploded (sounded like a gunshot went off in the vehicle). Most of the glass shot upward and behind us. The sunshade was closed so no one was injured, but this is a huge safety hazard to drivers in the vehicle as well as behind us on the road. The dealer is trying to pass it off as a rock hitting the windshield. I suppose there is no official way to prove whether this did occur, but EVEN SO, in any event, if a rock caused the sunroof to EXPLODE as opposed to just shattering or chipping that is a huge manufacturing safety issue. Sunroofs should never explode. The car is currently sitting at the dealer, I'm going to request a formal inspection.

The steering seems to be malfunctioning and is hesitant or sticking when operating the vehicle. The steering wheel seems to hesitate or stick only during left hand turns, even slight ones. If you do not manually pull the steering wheel back after turning, it will stay in the position and not return as it should. This issue posses a severe safety risk to my family and others if the steering component does not perform properly. An accident could easily occur as a result of this issue. The issue has not been confirmed by an authorized dealer yet. I am taking the vehicle to a Mazda dealership in the next week or so. No warning lamps or messages occur prior to or during the issue. This issue was first noticed 9/21/26.

I stopped for gas and when I removed the gas cap air came of out of the filler pipe like it was under high pressure. I could not fuel the vehicle because of the force of the air coming out of the tank blew gas out and shut off the pump. I started and shut off the car numerous times without the gas cap on and with it on which did nothing to affect the issue. It finally stopped after turning off all fans, radio and all accessories in the car and starting it without gas cap. The symptom lasted for more than 25 minutes. When I took my vehicle in for service they told me it was due to temperature change. I have not experienced anything like this with any other vehicle.

The vehicle utilizes I-Stop, which comes on when stopping and while traveling down the interstate when the computer isn’t registering throttle input as a way to increase fuel economy. At least a dozen times now, the vehicle has failed to register throttle input, which isn't allowing the vehicle to restart when traveling down the road. The tachometer will remain at zero even with the pedal all the way to the floor. This has even happened while traveling down [XXX] in Northern Virginia placing myself and my family at risk of a collision. We have taken the vehicle in for service and mazda has been unable to replicate the issue or successfully diagnose the problem.

My 2025 Mazda CX-90 PHEV has experienced multiple incidents of sudden, uncommanded hard braking when there was no visible obstacle or danger in front of the vehicle. The most serious incident occurred on September 4, 2026, during rush hour traffic. The vehicle beeped, a warning that said "BRAKE!!" appeared on the dash, and abruptly braked without driver input, creating a significant rear-end collision risk. My dog was thrown from the back seat as a result of the braking. Another unexpected braking incident occurred the following morning when I was backing out of my driveway. Similar unexpected braking behavior has occurred earlier in my ownership of the vehicle as well. I brought the vehicle to a Mazda dealership for diagnosis on September 10, 2026 (their earliest available appointment). They kept and tested the vehicle, but were unable to reproduce the condition or identify a cause. No repair has been made that explains or corrects the unexpected braking. On October 2, the dealership informed me that the vehicle was ready to be picked up and that they considered nothing to be wrong with it. The service manager, Rocky, told my husband that a "critter or shadow" could have caused the braking. I did not observe any squirrel, pedestrian, vehicle, object, or other hazard in front of or behind the vehicle during the incidents. I remain concerned that the vehicle may unexpectedly apply the brakes again, particularly in traffic and/or with my young son in the car. I do not feel comfortable driving it with my family while the cause is unidentified and no repair has been attempted. Mazda has been notified of the issue and I have requested a repurchase/buyback of the vehicle.

Recently, while driving our Mazda CX-90 (2025) we noticed a persistent and constant odor of fuel/gasoline vapors arise from the vehicle. We noticed this after driving the vehicle approximately 120 min from Las Vegas, NV to St. George, UT. The smell was intoxicating and nauseating. I took it into 2 local dealerships to investigate and called Mazda USA headquarters and spoke to a supervisor located in Irvine, CA. She explained to me that she gets complaints like this all the time during the summer months and that the larger Cx-90 is known to have the issue of leaking gasoline fumes/smelling of strong gasoline odor. I expressed my concerns for the safety of my family and surrounding environment including the flammable nature as well. The remedy that was provided was similar to the previous stating to park it outside and not fill up the gasoline tank greater than 3/4 full. I expressed that I drive a 2012 Honda Accord and do not have a gasoline leak nor strong odor of this magnitude nor have I ever experienced this before. We live in Las Vegas, NV. I am expected to drive my vehicle less and park it on the street all summer or when temperatures are above 100 deg? She stated, “We live in times where these newer vehicles are not made like the old ones.” I asked, “So is it this model that has the issue?” She replied, “Its the big one right, the CX-90? Yes, the bigger vehicles have this issue.” Is this considered normal to have a valve to release fuel vapors due to high pressures?

Incident

Aug 15, 2026

ISSUE 1 – UNINTENDED DECELERATION (Power Train): While driving at highway speeds (60–80 mph) with foot off accelerator for approximately 5+ seconds while coasting, the vehicle unexpectedly executes a sharp, single downshift causing sudden unintended deceleration and an RPM spike. No warning lights illuminate. Documented on 11 occasions between May 20, 2026 and July 29, 2026; incidents occurred prior to May 2026 but were undocumented. Occurs most frequently decelerating off highway exit ramps but also during general highway coasting in Houston, TX. A passenger was present during multiple incidents. Trailing vehicles are not anticipating the sudden speed reduction, creating rear-end collision risk. ISSUE 2 – FALSE BLIND SPOT / REAR RADAR ALERTS (ADAS): The Blind Spot Monitoring and Rear Radar Sensor systems generate daily false alerts — both audible and visual — when no vehicles or objects are present. Triggers randomly across varying conditions. False alerts have caused multiple aborted lane changes that were otherwise safe to execute. ISSUE 3 – LANE KEEPING ASSISTANCE (ADAS): The LKA system applies forceful steering corrections during intentional, signal-indicated lane changes, including in areas without lane markings. Occurs at highway speeds during on/off-ramp transitions. Corrections have triggered reactive maneuvers by surrounding drivers in dense traffic, causing near-collision situations. Dealer service appointment scheduled August 6, 2026.

I purchased this Mazda new in October 2025. Since purchasing the vehicle, it has unexpectedly applied the brakes on three separate occasions while I was driving under normal conditions. There was no reason for the vehicle to brake, and each incident created a dangerous situation because the vehicle slowed suddenly without my input. I brought the vehicle to my local Mazda dealership for inspection. The dealership was unable to identify a defect or repair the issue. I was told that the automatic emergency braking system may sometimes react to reflections and that this behavior is considered normal. However, I do not believe it is normal or safe for a vehicle to apply the brakes unexpectedly during normal driving. I no longer feel safe driving this vehicle, especially with my husband and young child as passengers. I am concerned that if the vehicle brakes unexpectedly again, it could cause a rear-end collision or another serious accident. I am submitting this complaint because I believe this may be a safety-related defect involving the automatic emergency braking/forward collision avoidance system. I am requesting that this issue be documented and investigated.

Incident

Jul 1, 2026

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.

I own a 2026 Mazda CX-90 hybrid with approximately 13,000 miles. The vehicle began making a grinding noise while driving, which has progressively worsened over time. It has since developed a hard knocking noise accompanied by noticeable vibration when the vehicle shifts gears. This knocking occurs during normal in-town driving. I have taken the vehicle to the selling/authorized Mazda dealership on two occasions — June 2, 2026 and July 14, 2026. On both visits, the dealer was able to reproduce and confirm the noise and knocking. The dealer stated they are aware other customers have reported the same issue, but that Mazda considers the noise/knocking acceptable and declined to perform a repair. No warning lights or diagnostic trouble codes have appeared at any point; the only symptoms are audible and physical. The vehicle is under both factory warranty and a purchased service/maintenance agreement. It has only been inspected by the selling dealership; no inspection has been performed directly by Mazda North America, law enforcement, or an insurance representative. I am concerned about my safety and the safety of others because a worsening, unexplained drivetrain issue that produces hard knocking and vibration during routine driving suggests a mechanical fault that could progress to sudden failure, and the manufacturer has declined to investigate or repair it further despite the symptom escalating across two documented visits. The vehicle remains available for inspection upon request.

My car is literally stalling out on me. It started by sputtering when I put my foot on the gas a week or so ago. Then today It literally started just losing power while driving. It’s not throwing any codes but that’s super dangerous and this car is only a year old. I am extremely concerned for my safety.

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.

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.

There is an intermittent issue where the dashboard will indicate that the rear side radar is obscured and turn off all the safety features of the car. This happens typically on a clear day when there should be no issues. Turning off the car resets this. Its unsettling because as there are quite a few blind spots in this vehicle you are dependent on the blind spot warning, especially in heavy traffic. Reported it to dealer but they indicated since its intermittent there isn't much they can do. Ridiculous for a new $45k vehicle

2025 backup camera not working with 8,500 miles on the car. This is a safety hazard and so far neither Mazda of Everett who broke it will not fix it unless I pay just about $1,300. They claim I have to talk to Mazda to see if they will warranty the part even though I have a 4 year 48,000 mile bumper to bumper warranty. There is no damage to the car what so ever and it has been inspected by the dealer since new with a 190 point inspection at 3,700 miles and never a problem with the camera. EITHER THE BACKUP CAMERA IS A BAD DESIGN THAT DOES NOT ACCEPT NORMAL USAGE OR THE DEALER DOES NOT TAKE SAFTEY FEATURES SERIOUSLY and broke it when washing the car.

I am submitting this complaint regarding my 2025 Mazda CX-90 PHEV, leased in April 2025. Since early in my lease, the vehicle has had ongoing drivability issues that have worsened over time and now present a serious safety concern.From the beginning, the vehicle exhibited jerking and hesitation while driving. Initially minor, this has become more frequent and now includes stalling behavior during normal driving conditions, including acceleration and traffic flow. This creates a risk of collision, especially when merging or at intersections.Approximately six months into my lease, the radiator failed and had to be replaced. More recently, while driving, multiple warnings appeared at once: Hybrid System Malfunction, Battery System Malfunction, Oil Monitoring Malfunction, and i-ACTIVSENSE partially disabled. These warnings were documented.Two weeks prior, the dealership reported no diagnostic codes. However, on my most recent visit, I was told via video that the active air shutter is now the issue. The required part is on backorder until August. I was told I could either remain in a non-comparable loaner while still making full lease payments, or continue driving the vehicle in its current condition until the part arrives. I find this unacceptable given the safety concerns.I expressed that I do not feel safe driving this vehicle, but the service advisor stated this is “not a safety concern.” I disagree. A vehicle that jerks, hesitates, or stalls while driving, combined with multiple system malfunctions and disabled safety features, presents a clear safety risk.I also disclosed prior to leasing that I do not have access to charging. I was told this would not be an issue. I am now being told that not charging the vehicle may be contributing to the problem. Service advisors have also indicated these vehicles have known hybrid battery issues.I no longer feel safe driving this vehicle and am concerned for my safety and my family’s safety.

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.
