While driving approximately 50 mph, we heard a sudden, extremely loud bang, followed immediately by the sound of shattering glass. We pulled over and discovered that the panoramic sunroof had shattered and appeared to have exploded outward. There was no collision, no object that we saw strike the vehicle, and no warning before the failure. The glass remained largely in place but was completely fractured. This occurred while my family was in the vehicle, including my young children. The sudden explosion startled the driver and created a potentially dangerous driving situation. I am concerned that a spontaneous sunroof failure at highway speeds could cause a driver to lose control of the vehicle or result in injuries from flying glass. I am reporting this because I believe it represents a serious safety issue that should be investigated to determine whether this is a manufacturing defect or other vehicle safety problem.
NHTSA complaint #11754493 — an unverified report by a vehicle owner.
When curving left my steering wheel will get “stuck”. It becomes heavy and then jerks back like it just “unlocked”. I haven’t had to pull it back forcefully, yet, but I’m sure it’s not far off. Went to Mazda dealership who state it’s mechanically related to a rack and pinion within the steering components. My car was part of the initial “sticky steering” recall which the previous owner had done in March of 2024. Happy to allow inspection if needed. My safety, along with the safety of others, is at risk anytime I travel along a curve where I could cross into on coming traffic because I am unable to forcefully move my steering wheel out of the “sticking” position. Potentially deadly. Mainly notice it around speeds of 45+ regardless of weather.
NHTSA complaint #11752549 — an unverified report by a vehicle owner.
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 am writing to formally notify you that I have officially filed comprehensive complaints with the NHTSA (National Highway Traffic Safety Administration), the Tennessee Department of Commerce and Insurance (TDCI, Case #202604748), and the Better Business Bureau (BBB) regarding Wyatt Johnson Mazda. I am submitting my vehicle's official Warranty Vehicle Inquiry Report as evidence of consistent technical issues and mismanagement by Wyatt Johnson Mazda. Please note the following: History of Repeated Technical Issues: The Warranty History shows a long list of repairs, including PCM/TCM reprogramming and other electronic service actions performed by the same dealer. This demonstrates that the vehicle has had ongoing, recurring technical problems that the dealer was well aware of. Contradiction in Dealership's Claims: Despite this extensive record of technical service, when I brought the vehicle in for the steering issue, the dealer claimed there was "no issue." This report clearly proves the dealer has been documenting and performing technical service on this specific VIN since 2023, making their claim of "no issue" highly suspicious and professionally negligent. Evidence of Neglect: The report confirms that my vehicle has been serviced exclusively by this dealer (Dealer 24014). They have full knowledge of the vehicle’s history, yet they chose to ignore the steering defect and attempted to charge me for a repair that should have been addressed under recall or warranty considerations. Bad-Faith Conduct by General Management: Furthermore, the Dealership General Manager persistently refused to acknowledge these documented defects. He went as far as bringing a technician to confront me, and despite me presenting this official warranty history as evidence, they dismissed it entirely and demanded $2,438 for a steering system replacement. I have photographic evidence documenting this interaction and the demand for payment, which confirms their bad-faith efforts to extort r

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.

The vehicle lurched to a complete stop and engaged the parking brake while entering the on ramp at FDR bridge in NYC. I had my whole family (7 of us) in the vehicle. Cars behind us had to slam on the brakes or swear to not hit us. The worst part is, the car had no option to put it into neutral to move the vehicle to a safe location. I sat praying for 45 minutes while we waited for a tow truck. Cars were flying past us as we were blocking 2 lanes of traffic, one of which was the on ramp. They could not see us as they were coming around a corner. Several accidents almost happened. There was nothing we could do but sit there. This is a known issue with Mazda CX 90 2024 PHEV system. Mazda did not warn me in any way that if the vehicle has an issue with the PHEV system, it was going to disable the vehicle to the point that you are unable to put it into neutral. There was no way to disengage the parking break. The vehicle was towed twice with the break engaged.

Vehicle radiator cracked at 31k miles on the highway leaving myself and my family stranded. My roof has been leaking since I bought the vehicle and Mazda keeps saying they can't replicate the issue and if I can find it they will then fix it. I don't think that's my job. I bought a car that I expected to be able to drive safely without issues. I don't want to play find the issue because I'm not a mechanic or manufacturer. It has been in and out of the shop since purchase in October 2023. Longest period was about 28 days. It's currently in the shop for the radiator and many people are having the same issue. They say I am 3 weeks past warranty but with these items being known issue I don't want to have to pay for them.

When turning on the heater or AC, the car blows out a coolant smell out of the vents. It does it every time the heat is turned on or switched over to AC. We have another appointment with the dealership to have this looked at, as well as many other issues we're having with this vehicle.

I am reporting a persistent and dangerous "sticky steering" defect in my 2024 Mazda CX-90. While driving at various speeds, the steering wheel exhibits sudden, momentary resistance and physical binding, requiring increased manual force to overcome. In several instances, the vehicle veers into other lanes and, if not corrected, would enter into the median/other lanes of traffic. This vehicle has been to the dealership three times for this specific issue and has been out of service for a cumulative total of 36 days. Despite a "repair" attempt by the dealership, the nonconformity persists. The dealership initially attempted to attribute this mechanical binding to the Lane Keep Assist (LKA) system; however, I have personally conducted road tests with the LKA system fully disabled, and the physical "stickiness" remains present. I am aware of NHTSA’s 2026 Recall Query (RQ26) regarding the effectiveness of Mazda’s steering remedies for this model. Even though my vehicle does not fall under the recall for this issue, my vehicle is currently exhibiting the exact failure symptoms that the federal government is investigating as a potential safety risk. The sudden increase in steering effort is unpredictable and poses a significant risk of over-correction or loss of control, especially in highway traffic. During the most recent repair attempt by the dealership, they were unable to duplicate the issue; however, it is very prominent and concerning. There is no warning of when it will occur. If the vehicle veers over the line on either the right or left, the lane keep assist (LKA) will engage to correct the vehicle. In some instances, the resistance is too strong for the LKA to correct the vehicle, and it requires driver correction.

Started the car to go to work and the check engine light came on, I stop started flashing and wouldn’t turn off. Message says there is a malfunction with the hybrid system and to visit Mazda dealer. I had to drive it to work, so it drove fine. But the lights never went off.
NHTSA complaint #11727151 — an unverified report by a vehicle owner.
I am reporting a serious safety defect involving unintended acceleration in my 2024 Mazda plug-in hybrid vehicle. On multiple occasions, the vehicle has suddenly accelerated without input from me, creating dangerous situations where I nearly lost control and risked a collision. This issue has occurred at least four times since January 2026. I previously brought the vehicle to an authorized Mazda dealership, where it remained for approximately two weeks; however, they were unable to replicate the problem and returned the vehicle, stating no faults were found. Despite this, the unintended acceleration continues to occur intermittently. I have attempted to follow up with both the dealership and Mazda corporate without receiving a response. This ongoing issue poses a significant safety risk to myself, my passengers, and others on the road.

I am reporting a safety defect involving my Mazda CX-90 with approximately 1,400 miles. The vehicle emits strong chemical fumes into the passenger cabin during normal operation. I first noticed it the night I purchased the vehicle when I was driving it home. The fumes occur both with and without the HVAC system in use. Once present, the odor lingers inside the cabin for an extended period, even after the vehicle is turned off. The exposure causes physical symptoms, including headaches, burning eyes, watering, and irritation while driving. The severity of the symptoms raises concern that harmful fumes or gases are entering and remaining inside the vehicle cabin. The vehicle has been taken to Mazda service centers twice and it is currently there for the third time. The dealerships have stated they are unable to detect the odor and has not performed any effective repair. The condition persists and continues to affect occupant safety. This issue is not consistent with a typical “new vehicle smell.” The intensity, recurrence, and physical symptoms suggest a potential defect allowing chemical or exhaust fumes to enter the passenger compartment. I am submitting this complaint due to concern for my safety and the safety of passengers, and to request investigation into whether this is a broader defect affecting this vehicle model.

On March 14, 2026, I was attempting to turn left into a parking stall within a busy shopping center lot when my vehicle suddenly accelerated unexpectedly. I lost all control of both the steering and the braking systems. This resulted in my vehicle striking a parked car to my left, jumping a cemented planter border, and coming to rest in the adjacent parking stall. Fortunately, the other vehicle was unoccupied, and both my passenger and I were uninjured. Local law enforcement was contacted; however, they indicated the policy officers will not be sent to the seen to file a report as there were no injuries. They did assist in identifying the owner of the other vehicle. I have initiated a claim with my insurance carrier, American National Property and Casualty Co (Claim #10401408), and have opened a case with Mazda Corporate (Case #00428640). Mazda has indicated that they require a report from my insurance provider to proceed with a technical investigation. Please advise what other steps I need to take.

NOTES FROM SERVICE TO MY CX90 MAZDA FROM HILEY MAZDA OF HUNTSVILLE 256-578-1915 During my last oil change with Maza on Nov. 12, 1pm the dealership noticed my windshield wiper fluid leaking into the radiator. They had to order a new radiator and repair this problem. They gave me a loaner CX90 for a week until a new radiator and parts arrived. On Dec 03 new radiator came in and my Mazda dealership and they replaced the radiator and windshield wiper mechanisms. Now on [XXX] I noticed my coolant reservior was empty while I was filling my windshield washer reservior. I drove my vehicle to the nearest Kelley Car Parts store and they filled the reservior for me and suggested I get the vehicle to Hiley Mazda asap. I called Mazda on Monday March 2 and they said to bring the vehicle in on March 3 at 1pm. They are now keeping my vehicle to find out what the problem is. I believe they never replaced the new radiator properly. I now have been give a CX50 as a loaner while they again try to fix my car. I am [XXX] and should not have to deal with this. A Mazda 2024 CX90 with only 20, 202 miles on it should not be having these issues. I researched and have found out the Mazda CX90s are having major problems with the radiators leaking from the sides and customers have to have their radiators replaced. This problem should not be happening to a vehicle I purchased brand new [XXX]. I believe Mazda should replace my vehicle with a new vehicle.

My car is giving me various problems with a gear box(a) and accelerations(b). a. It shift from one gear to another on its own. The gear can be put in Reverse, but the light would indicate Park, and the car would not move. Sometime I put the car into Drive and the Parking Break would come up and wont let me release it until I put the car back into Park mode. I've already had multiple"glitches" like this. Couple of weeks ago, when coming out of a stop sign, the gear shifted from Drive into Neutral in the middle of intersection with 2 minors in the car. b. The car experiences acceleration problems every time it come from a stop. It moves very slow and "jerks" as if it is about to shut down. This problem has gotten getting worse in the last couple of weeks. I brought the car to Mazda dealer last summer, as the gear box would take forever to unlock for driving. They said it is normal and thats just like the car is. I have my 3 children [XXX] and [XXX] ) with me 95% of my driving. I have big concerns about this vehicle and its safety.

NHTSA complaint #11721941 — an unverified report by a vehicle owner.
I purchased a new 2025 Mazda CX-90 Plug-In Hybrid, which currently has approximately 16,500 miles. Despite normal daily driving, proper maintenance, and all scheduled services performed at authorized Mazda dealerships, all four original tires have prematurely worn out and require full replacement. This level of tire wear is abnormal and significantly below the expected lifespan for a vehicle of this type. Mazda representatives have verbally acknowledged that premature tire wear is a known issue with this model, reportedly related to the vehicle’s weight and design, yet no corrective action, repair, or warranty assistance has been offered. This defect creates an unexpected financial burden and raises safety concerns for a family vehicle used daily to transport children. Based on current wear, this issue will require tire replacement on a yearly basis, which is unreasonable for a high-purchase-price vehicle of this class. I am seeking a fair resolution, including reimbursement for premature tire replacement and appropriate corrective measures to address the underlying cause of the excessive tire wear.

Component Involved: Front suspension – Lower control arms Braking system (ongoing unresolved brake noise) Description of the Safety Issue: The front lower control arms on my 2024 Mazda CX-90 show visible erosion/corrosion and looseness. The condition was identified during inspection by a national tire service center and documented on video. The component remains on the vehicle and is available for inspection. The dealership has been notified of persistent brake noise during the last five oil change visits, but the concern has not been resolved. Safety Risk: The loose and eroded lower control arms create a significant risk of: •Loss of steering control •Suspension instability •Increased likelihood of component failure •Potential crash risk at highway speeds There were no warning lights related to suspension failure prior to discovery. The defect was identified during independent inspection rather than through vehicle alerts. Confirmation: The condition was observed and documented by an independent service center. The manufacturer has not yet conducted a formal inspection beyond routine service appointments. No crash has occurred to date, but the condition poses a clear safety risk. Additional safety information will be provided once the inspection is complete.
