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.

My 2024 Mazda CX-90 PHEV Premium Plus has experienced repeated hybrid system failures. The vehicle currently has an active "Hybrid System Malfunction" warning light. This is the latest in a series of 17 recalls and recurring defects since purchase in July 2023. Most recently, the vehicle was out of service from February 14, 2026 to approximately March 18, 2026 due to a severe transmission fluid leak, which the dealer (Nealson Mazda Cool Springs, TN) acknowledged was common in this model. The current hybrid system malfunction warning poses a direct safety concern as it affects the vehicle's powertrain and reliability. I am a daily driver of this vehicle and have two young children who ride in it regularly.
Low voltage battery system Safety is at risk because vehicle could loose power and be forced into a turtle mode cause injury from sudden slow down Yes there were warning lights This is a continued problem identified but other owners and consistently replaced
The contact leases a 2024 Mazda CX-90. The contact stated that on two separate occasions while stopped and the ON/OFF feature was activated, the vehicle shut off. The contact stated that several warning messages including the "Engine Malfunction ", "Charging System Malfunction", and "Eye Active Sense System Malfunction" appeared on the instrument panel. The contact then stated that she had received a recall notice for the federal safety agency Campaign Number: 24V816000( Electrical System, Power Train). The vehicle was taken to the dealer and the vehicle was serviced. The contact stated that while driving at a 20 MPH, the vehicle shut off as the previous warning messages appeared on the instrument panel. The contact managed to restart the vehicle; however, an audible beeping sound persisted. Due to the failure, the contact pulled over and had the vehicle towed to the dealer. The dealer kept the vehicle for nearly two weeks where they replaced the mild hybrid battery. Despite the latest repair, the contact expressed concern about the vehicle being that the failure occurred while her two young children were in the vehicle. The manufacturer was notified of the failure in a letter and requested to have them replace the vehicle under her lease. The manufacturer denied the contact's request and closed the case. The failure mileage was approximately 31,000.
The car thinks the key fob is inside the vehicle when it is not. If you get out of the vehicle it will not self lock even if you have that feature set up. It will also beep consistently for about 10 seconds when you press the lock button on the key fob when your outside of the car, indicating that there is a key fob in the car....but there is not. The most concerning thing is you can get into the car and start it without any key fob inside the vehicle. It always thinks the key fob is in it, at all the time and will start without any key fob in it. This is not an occasional thing. It has been like this since we pirchased it from Mazda as a CPO vehicle. It's been doing this for all 2 months that we've owned it. We currently have an appointment with the dealership to take it in for them to hopefully fix it as well as other issues.
The vehicle experienced a sudden and repeated malfunction of the hybrid/electrical system and powertrain, resulting in the vehicle becoming inoperable. The vehicle is currently at the dealership and is available for inspection upon request. While driving in traffic, multiple warning messages appeared, including "Hybrid System Malfunction," "Charging System Malfunction," "Engine Malfunction," "Brake" and "i-ACTIVSENSE System Malfunction." The vehicle lost functionality and could not operate normally, creating a dangerous situation in active traffic. I was forced to slowly maneuver the vehicle to the shoulder after several restart attempts. This issue has been reproduced multiple times. The vehicle has previously been inspected and repaired by an authorized dealership, including recent repairs (12V battery and engine mounts). Despite these repairs, the same critical malfunction occurred again shortly after the vehicle was returned as repaired. The vehicle is currently being inspected again by the dealership. The issue has not yet been permanently resolved. Prior to the failure, the vehicle had a history of similar warning messages and abnormal behavior beginning at approximately 20,000 miles. These issues have continued intermittently despite multiple repair attempts. The repeated failures, including the most recent incident, indicate an ongoing unresolved defect that creates a significant safety concern. This issue is a continuation of a previously reported complaint (the federal safety agency Report No. 11734505).
1) What component or system failed? The issue appears to involve the vehicle’s electrical system and hybrid system, as well as brake-related electronic systems. The vehicle displayed multiple warnings including “Hybrid System Malfunction” and “Critical Vehicle Malfunction.” The electronic parking brake system was also affected during the incident, including a situation where the brake could not be released while the vehicle was in motion. The affected components are available for inspection upon request. 2) How was safety put at risk? Safety was put at risk because the malfunction occurred while driving and involved critical system warnings and brake-related issues, including the inability to release the electronic parking brake. The sudden appearance of a “Critical Vehicle Malfunction” warning during operation created concern about potential loss of vehicle control and safe braking capability in traffic. 3) Has the problem been reproduced or confirmed by a dealer? The issue has not been fully resolved. The vehicle previously underwent service for a high-voltage hybrid battery replacement, but the current symptoms continue to occur repeatedly. The problem has not yet been confirmed as permanently resolved by the dealer. 4) Has the vehicle been inspected by manufacturer, police, insurance, etc.? UNKNOWN 5) Were there warning lamps or symptoms before failure? Yes. Over the past two weeks, multiple warning lights and messages have appeared almost daily, including: Check Engine Light Hybrid System Malfunction i-Stop malfunction Intermittent brake / electronic parking brake warnings A “Critical Vehicle Malfunction” warning occurred once while driving, along with multiple simultaneous alerts. These warnings sometimes disappear after restarting the vehicle but consistently reappear during normal driving.
The contact owns a 2024 Mazda CX-90. The contact was informed about a previous recall associated with the steering that was repaired prior to owning the vehicle, but the failure persisted. The contact stated that while driving on several occasions at various speeds and turning, the steering wheel jerked in the opposite direction, then became soft, and then more difficult to steer. The vehicle was not diagnosed or repaired, but the contact was informed of a steering investigation. On another occasion, the contact stated that when the vehicle was stopped and the ON/OFF feature was activated. There was an abnormal knocking sound coming from the engine compartment. The contact stated that after turning off and restarting the vehicle, and after refueling the vehicle, the messages "Engine Malfunction – Inspect Vehicle" and "Hybrid System Malfunction" was displayed. The check engine warning light was illuminated. The vehicle was not diagnosed or repaired. The manufacturer was notified of the failure. The failure mileage was 56,050.
Since taking delivery of this vehicle in June 2024 from Kenny Ross Mazda, I have experienced a persistent and unresolved error message on the vehicle’s display screen relating to “Multiple ECUs Reprogramming.” This error message first appeared within the first twelve (12) months of ownership and has remained continuously present on the vehicle’s instrument cluster/infotainment screen despite numerous repair attempts. The defect substantially impairs the use, value, and safety of the vehicle, as it creates constant uncertainty about the operational status of critical electronic control systems, diminishes the vehicle’s resale value, and interferes with my normal use and enjoyment of the vehicle. Photographic evidence of this error message is attached as Enclosures 2 through 5. I have brought the vehicle to Rohrich Mazda, an authorized Mazda dealership and service facility located in Pittsburgh, Pennsylvania, on at least seven (7) separate occasions over the past twelve (12) or more months in an effort to resolve this defect. Each time, the dealership has been unable to eliminate the error message. During the course of these repair attempts, the dealership initially believed the issue was related to a recall (Safety Recall 7024J — Multiple ECU’s Programming), but subsequent repair attempts have failed to resolve the condition. The dealership has contacted Mazda Corporate technical support on multiple occasions, and Mazda Corporate has been unable to provide a solution. As of this writing, the dealership and Mazda Corporate have acknowledged that they do not currently have a fix for this problem. The service ticket remains open.
Incident 1: While driving my 2024 Mazda CX-90 PHEV at low-to-moderate speed, the vehicle suddenly and completely locked up without any driver input. There was no gradual slowing or normal braking behavior. Instead, the vehicle went immediately from moving to an abrupt, forceful stop, as if maximum braking was applied instantly. There were no warning lights, alerts, or audible signals before or during the event, and there were no obstacles or vehicles in front of me. Incident 2 (approximately 6 months later): A second, nearly identical event occurred while I was accelerating or cruising. The vehicle again immediately locked up and came to a sudden stop with no warning and no driver input. There was no progressive braking or deceleration. The stop was instantaneous and extremely forceful, causing me to lurch forward into the steering wheel. There were no hazards or objects present that would justify emergency braking. Additional Details: Both events involved an immediate, full-force stop with no transition or gradual braking. There were no dashboard alerts, warning sounds, or messages during either incident. The behavior did not match any known system alerts (such as door open or limp mode). The dealership was unable to reproduce the issue and found no diagnostic trouble codes. This creates a serious safety risk, especially the risk of being rear-ended during normal driving.
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.
The car had a recall repair to the steering system done due to it being sticky. But the issue has coma back again while driving on ramps and curvy roads. The steering requires significantly more effort and also has a feel of a ratchet. It also feels like a ratchet, when moving very slow and making tight turns. The car also had a recall battery replacement done for the MHEV battery and now the problem is back again within a few months and it shows "Hybrid system failed" and "Engine malfunction".
Reporting multiple safety-related defects on my 2024 Mazda CX-90. Steering system: At approximately 5,000 miles, the vehicle developed abnormal steering behavior, including inconsistent steering response and abnormal feel during normal driving and turning. The condition affected my ability to steer the vehicle predictably and raised safety concerns, particularly during low-speed turns, parking maneuvers, and city driving. The issue was confirmed by the dealer and required replacement of the steering rack, a major steering component. The vehicle remains available for inspection upon request. Hybrid system: At approximately 22,000 miles, the vehicle experienced a hybrid system malfunction that required the vehicle to be taken out of service for an extended period. The malfunction affected drivability and reliability and required dealer diagnosis and repair. The vehicle was inspected and repaired by an authorized Mazda dealer. Braking system: The vehicle has experienced ongoing abnormal brake squeaking during normal driving and low-speed braking. While braking function remains present, the abnormal noise raises concerns about brake system integrity, wear, and long-term braking performance. Electrical / infotainment system: The infotainment system intermittently shuts off or resets while driving without warning. When this occurs, the display goes blank and then restarts. This results in loss of access to navigation, rear camera display, vehicle settings, and driver-assistance information, creating driver distraction and a potential safety risk. These issues occurred on a relatively new vehicle and involve critical systems including steering, drivetrain/hybrid, brakes, and vehicle electronics. The combination of defects raises concerns about vehicle safety, reliability, and loss of driver confidence. Warning messages were present for the hybrid malfunction; other issues occurred without warning. The vehicle has been inspected and repaired by authorized Mazda deal
Need a recall for, P0DAB - Hybrid battery cell balancing conformance error code. Thousands of 2024 CX-90 customers experiencing the issue and MAZDA USA is not responsive. All of the 2024 vehicles are LEMONS and the federal safety agency should force Mazda to replace these lemons with a new model for the safety of the US citizens.
I have a 2024 MAZD CX-90 Preferred Plus AWD. I was driving my [XXX] grandson to preschool and it sounded as though the passenger's door opened while I was driving. In the split second I looked back to check, unfortunately, I hit a guard rail. My grandson was buckled in his car seat. his first words were "Meme, the door opened but I didn't do it". He was buckled in his car seat and I believe the safety door locks were on. There was no warning sound or light indicating the door was open while I drove. I pulled over, got out of the car and looked. the passenger's back door handle was positioned up but the door was closed. being so shook up, I didn't think to take any pictures. I then had messages on my car saying Dynamic Stability control malfunction - have the vehicle inspected and Engine Malfunction - have the vehicle inspected. I called my dealership to find out if there were any recalls on this type of problem (they said that there weren't any). I have come across a forum where a person states: "So can confirm 1st row passenger door does not provide any warning as well. Looking at the manual, I see that there is supposed to be a warning sound when any door/hood/liftgate is open while driving, as quoted below. If someone else confirms this is normal behaviour, then I think we should file a safety defect complaint with the federal safety agency and Transport Canada. “Door-ajar Warning Light/Liftgate-open Warning Light/Hood-open Warning Light The light turns on if any door/liftgate/hood is not closed securely. In addition, the warning sound is activated if any door/trunk lid/liftgate is not closed and the vehicle is driven. Close the door/liftgate/hood securely.” This was a very scary situation. I absolutely will concede that something did happen with this rear passenger door. INFORMATION REDACTED PURSUANT TO THE FREEDOM OF INFORMATION ACT (FOIA), 5 U.S.C. 552(B)(6)

I am reporting an unresolved safety-related defect with my Mazda CX-90. The vehicle began experiencing repeated malfunctions affecting reliable operation while being driven. The issue was reported to the dealer while the vehicle was still under the manufacturer’s original warranty. The vehicle was taken to a Mazda dealership for diagnosis and repair. The problem has not been resolved, and the vehicle has been held at the dealer for over 30 days. I was provided a manufacturer loaner vehicle because my vehicle has not been deemed reliable to return to service. Mazda North America has escalated the issue and informed the dealer that they are “waiting on Japan” for engineering guidance, indicating there is currently no approved repair or resolution. As of now, no permanent fix has been identified. This defect raises safety concerns because the vehicle’s reliability cannot be assured, and returning the vehicle to service without a confirmed repair could put occupants and others at risk. The extended out-of-service time and lack of an approved repair suggest a potential systemic issue. The vehicle remains available for inspection and is currently in the possession of the Mazda dealer. -
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.
The contact owns a 2024 Mazda CX-90. The contact received notification of the federal safety agency 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 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."
Brought vehicle into Dealer for Service due to Check Engine Light being on and Notification of a Malfunction of the I-Stop System. Service Tech indicates that this is a known issue with the Hybrid Battery in these vehicles that could cause the vehicle to unexpectedly stall. This safety issue is significant enough that they would not let us take our car home while we wait for them to obtain a battery, which are currently on backorder. Pursuant to a conversation with a Mazda Customer Experience Representative this has been a known issue since at least January. We have not received any correspondence from Mazda regarding this issue. It would appear that a Bulletin or Recall is warranted for what appears to be a prevalent issue with significant safety impacts.
The contact owns a 2024 Mazda CX-90. The contact received notifications of the federal safety agency Campaign Numbers: 24V814000 (Electrical System, Structure) and 24V815000 (Power Train, Engine and Engine Cooling); and parts were available. The contact stated that upon taking the vehicle to the dealer, he was informed that the manufacturer would not cover the cost of the repair. The manufacturer was made aware of the issue and confirmed with the contact that as the second owner of the vehicle, he was not entitled to have the cost of the repair covered by the manufacturer. The contact had not experienced a failure. Parts distribution disconnect.
Hybrid battery failure. Battery issue can cause car to lock up while driving. Dealer service department indicate they have at least 6 vehicles with this same issue. The vehicle has not been inspected by other than the dealership service department that I am aware of. While driving to the dealership for a routine oil change, the car made a quick odd noise then 3 alerts came on said Hybrid system malfunction have vehicle inspected, engine malfunction, system malfunction. Dealer inspected vehicle determined needed a hybrid batter replacement, indicated they could not say vehicle was safe to drive as it could just stop working. Considering they already have a number of cars with same issues in the shop I am concerned this could be a defect problem in many vehicles.
Bought this brand new CX90 Premium in October 2024! As of today Feb 11, the car has been in the dealership 4 x fir the same issue!! Dead battery after sitting for 2 weeks! They have replace one small battery and that worked for a month! Took it in last week for the same issue! Dead battery! We find that this is a very coming problem. They said they would now replace the 58 volt battery but it is on back order for 8 weeks. In the mean time I’m paying on this car and I have to drive a loaner which isn’t even close to my car! I’m finding out by talking to other customers this is a common problem! We didn’t get any notice or call! I am demanding this be considered “lemon law” as this is the fourth time it has been in for the same problem. I want all my money back that I paid and demand Mazda USA issue recalls for this issue. It is definitely a big safety issue! The dealer seems to be trying but they are frustrated as well! They are Olympia Mazda in Olympia, Wash, service manager is James Ellis Please respond!

The fuel gauge and range indicator are faulty. I was doing long-distance highway driving during the holidays. At 1/4 tank, the range indicator said 110 miles until empty. As soon as the needle dipped a fraction below 1/4 tank (about 20 miles later) the range indicator dropped instantly to 40 miles left AND THEN DROPPED ONE MILE PER SECOND UNTIL IT REGISTERED ZERO. The needle also fell at the same rate until I was driving on the interstate with zero range and a gas gauge buried below empty. All of this occurred within one minute. I pulled into the nearest gas station and filled up with 12.71 gallons (it's an 18.5 gallon tank). So I actually had 5.79 gallons left (or 156.33 miles of range at 27mpg on the highway). Not being able to rely on the gas gauge/range indicator is a safety issue.
Stopped at a red light on a busy 2-lane road. I-stop function turned the engine off. When the light turned green, releasing the brake caused a "Hybrid Battery Malfunction" error and the engine failed to start. We put the transmission in park and attempted to turn off and turn on the car with the push to start button. When we attempted to start the car with the push to start button, the car would not start. We were unable to shift into neutral to move the car out of the busy 2-lane highway and were blocking traffic for about an hour. The first tow truck to arrive was unable to move the car onto the flat-bed because the transmission was stuck in park and would not go into neutral so another tow truck was dispatched with a dolly. Our safety was at risk because we were stuck in an immobile car in busy highway traffic. A police officer arrived to help direct traffic around our disabled car. The vehicle is currently at the dealership and has not been inspected as of the time of this report.
There has been two dangerous failures both occurring in an intersection. First instance was in December of 2023 whey the fuel pump failed while turning in an intersection. The second incident was a hybrid battery malfunction, rendering my vehicle unusable in the middle of an intersection again. This was 03/2023
The major issue that happened to our newly purchased CX 90 last February 3 with more than 500 miles on it started around 5:30 pm of February 8, while my wife is driving this vehicle with my daughter, all of a sudden the car stopped at the middle of the road with warning signs popping up in the dash screen like I-active sense malfunction, hybrid battery malfunction, engine malfunction light on, and on top of these, critical vehicle malfunction. The car won't start and disabled. Also, the vehicle cannot switch to neutral gear to push/pull the vehicle to the side that made the vehicle blocking the roadway until the tow truck came in. My wife and daughter's life was put in danger when this vehicle suddenly stopped in the middle of the road with cars passing by on both ways. I also found out based on the federal safety agency vehicle safety, Mazda recall website, carfax and Kelly blue book, that this particular vehicle with its VIN has a SAFETY RECALL due to its steering issue that may increase risk for crash. This was not disclosed to us when we are on the process purchasing this vehicle and they did state inspection and passed it that made we doubt how did it happened.. The vehicle is now with the dealership repair shop and the last update I receive was the technician is still checking on it.
On 02/07/2024, malfunction prompts displayed on my dash relating to I-stop functionality, hybrid functionality, engine. Took the vehicle the next day to be diagnosed, the appointment was set as an inspection with oil change, filter change, and the prompts on my dash. I was advised that the issue to the prompts stemmed from the hybrid battery. I was told that contact was made to the manufacturer and that the battery would have to be replaced. The battery is on backlog and it would be about a month to arrive. I called in after leaving with additional questions as to the safety of the vehicle with the hybrid battery problem. The man on the phone said it is safe to drive, what would be affected would be the mileage I would not get because the hybrid portion was not functioning. He mentioned that a separate case was created with another 2024 cx-9 car owner with the same hybrid battery issue. It’s now two known cases with the hybrid battery issue. I called customer service and was provided with case number 00174049. The resolution to that call to corporate customer service is that I would receive a call back from the local dealership about a loaner car with about an hour. I became aware of a fourth recall, that the corporate agent referred to as a campaign, pertaining to the steering wheel. I asked my dealership advisor if that can be looked in addition to the other issues. She stated that she could not because it has not been launched. The corporate agent advised me that notification would normally happen 2-3 weeks. I looked up the steering wheel recall on the dep of transportation website. The recall has been published since the 18 of Jan 2024 and have yet to receive notification. I only found out today when I took the vehicle in for inspection.
The contact owns a 2024 Mazda. CX-90 The contact stated while driving at undisclosed speeds, the blind side detector inadvertently illuminated. The contact stated that the blind side detector randomly illuminated without an object being nearby. The vehicle was taken to the dealer where it was diagnosed that the blind spot sensors failed and needed to be replaced. The vehicle was repaired; however, the failure recurred. The vehicle was taken back to the dealer, but the failure could not be duplicated. The vehicle was not repaired. The manufacturer was notified of the failure and the contact was provided a case number. The failure mileage was approximately 1,300.
