2024 Mazda CX-90-PHEV

While driving through a busy intersection with my family inside the vehicle, my 2024 Mazda CX-90 suddenly experienced a complete loss of propulsion. Pressing the accelerator pedal produced no response, leaving the vehicle unable to accelerate or maintain speed. The vehicle displayed warning messages stating “Engine malfunction” and “Stop safely and shift to Park.” I was forced to rely on the vehicle’s remaining momentum to coast out of the busy intersection and into a nearby gas station. This unexpected loss of propulsion created an extremely dangerous situation and placed my family at serious risk of a collision with surrounding traffic. Following the incident, the vehicle was taken to Hiley Mazda, where technicians diagnosed a failed 48-volt mild-hybrid battery and ordered a replacement under warranty. A leaking radiator was also discovered during the same service visit. This vehicle has an extensive history of electrical malfunctions, abnormal i-Stop operation, software-related issues, and previous safety concerns. However, this incident was particularly alarming because the vehicle completely lost propulsion while operating in active traffic. I am extremely concerned that this type of failure could occur in other Mazda CX-90 vehicles, potentially resulting in a serious accident or injury. I am requesting that NHTSA investigate this sudden loss-of-propulsion failure and determine whether it represents a broader safety defect affecting Mazda’s 48-volt mild-hybrid system.

I am reporting a potentially dangerous steering defect in my Mazda CX-90. The steering problem initially developed approximately two months ago at around 8,500 miles and has progressively worsened. The vehicle currently has 9,443 miles, and the steering now catches or binds during nearly every low-speed turn. Specifically, when making turns at approximately 10 mph, the steering wheel appears to catch or become stuck about halfway through the turn. I must apply additional force to overcome the resistance and straighten the steering wheel. The steering does not move smoothly or return to center as expected. This is no longer an occasional occurrence. It happens during nearly every low-speed turn, making the vehicle's steering unpredictable and unsafe. I have owned and driven numerous vehicles and have never experienced this behavior. My wife refuses to drive the vehicle because she does not feel safe operating it. I am concerned that the unexpected steering resistance could result in a loss of vehicle control or an accident. I recently learned of Mazda's steering recall (NHTSA 24V-022), involving excessive friction in the electric power steering worm gear assembly, and a subsequent NHTSA investigation into reports of similar steering problems. I have scheduled a dealership service appointment for October 20, 2026, to have the steering system inspected. Given the increasing frequency and severity of this issue, I am requesting that NHTSA investigate whether my vehicle is experiencing the same steering defect identified in previous complaints and determine whether additional corrective action is necessary.

We recently purchased a used 2024 Mazda CX-90 and noticed that upon driving on winding roads at approximately 35-45 mph when turning the wheel on a curve in the road, the steering wheel would stick in position and then fight to go back to center. It almost felt like the steering wheel was fighting me. After about a week of driving the vehicle both my wife and I experienced the same issue. We noticed that when turning to the left, it stuck in position longer than when turning to the right but in both directions, the same issue occurred. We brought it to the dealership and they said they could not recreate the issue and said the car is fine. I do not feel safe driving the car and now we are stuck with it.

The component of concern is my interior rearview mirror and it's mounting piece. While i was driving the entire rearview mirror and it's mounting piece detached together and fell off. there was no collision , and there was no visible damages to the windshield. The exact cause of detachment is unknown. The safety concern is the interior rearview mirror used to see traffic behind the vehicle is no longer available that was included with my vehicle. The unexpected detachment affected my ability to use the mirror while driving. I had my care serviced in Maryland at the dealer service center and my rearview mirror and it's mounting was inspected for broken pieces . The rearview mirror and mounting was repaired at the service center after the inspection. As soon as i pulled off made a right turn at the first traffic light the mirror and mounting fell down . I returned within minutes to the same service center and was given a refund and was informed the tech can't fix the mirror / mounting. I reported the issue to Mazda Corporate and requested assistance. Mazda declined to provide goodwill assistance after the dealership service manager classified the issue as an external concern . My auto insurance company advised me that the incident falls under mechanical breakdown and is not covered . No warning messages prior . I am requesting that this incident be documented and reviewed to determine whether a defect involving the rearview mirror mounting assembly or attachment may have contributed to this failure. The detached mirror and mounting pieces may be available for inspection upon request. The specific componet failure has not yet been independently confirmed.

No specific incident happened however, oftentimes while driving, I experience "stickey steering" which I have researched and appears as though affected 2024 CX-90 Mazda's. Whili I am driving around sharp turns or on/off ramps that are curved, my steering wheel gets stuch and I have to manually ensure that when I am straightening out the steering wheel, that I don't over correct, merge over the cross line or hit another oncoming vehicle.

I took my 2024 Mazda CX-90 PHEV to the Mazda dealership due to a sticky steering and jerking while turning at high and low speeds. I did some research and found Safety Recall 6524A. The dealership said my vehicle did not have any pending/open recalls so they could not do anything with that information. They charged me a diagnostic fee, and recommended a complete steering rack replacement. However, I am outside the warranty for my vehicle. I checked the Mazda Recall info webpage myself, typed in my VIN and the recall does show up as CLOSED. I would like to have this safety recall re-repaired, since it is a safety concern for me and my family. This issue has almost caused me to have an accident more than a few times at high speeds, and this safety recall 6524A EXACTLY describes the problem. I have no information as to when the recall was repaired on my vehicle, as I purchased it used. No other symptoms or warning lights have popped up, and I have noticed this issue a few weeks ago.

Safety Recall 6524A (NHTSA Campaign 24V022000) was previously performed on this vehicle. However, the 'sticky steering' and sudden increase in steering effort have entirely returned. The dealership is stating a full steering rack replacement is required but Mazda is denying warranty coverage due to mileage. This is a recurring safety defect that the initial recall remedy failed to permanently resolve.

The contact owns a 2024 Mazda CX-90. The contact stated that the vehicle was previously repaired by a dealer. While driving, the vehicle lost motive power. The contact turned off and restarted the vehicle. Additionally, the front passenger’s seat failed to move as needed. The vehicle was taken to the dealer, and it was determined that there was a radiator and battery case leak. The contact was informed that the vehicle was unsafe to drive and was provided a loaner vehicle. The dealer replaced the battery and the front passenger’s seat electric switch. The battery case and radiator needed to be replaced. The manufacturer was notified of the failure by email. The failure mileage was 46,464.

The contact owns a 2024 Mazda CX-90. The contact stated that the steering rack coil was previously replaced under a recall. The contact stated that while driving 40 MPH off the highway, the contact suddenly lost steering and directional control, and the vehicle independently veered out of the lane. The contact was able to regain control after several attempts. The contact initially believed that the vehicle had hydroplaned; however, the failure reoccurred a month later. The contact stated that while driving 35 MPH on another occasion, the driver completely lost steering and directional control. The vehicle independently veered to the left and moved uncontrollably while the contact attempted to turn right. The steering wheel felt firm and was stuck before overcorrecting, causing the rear passenger’s side rim to strike a curb on the right. The vehicle was towed to the dealer, where it was diagnosed and determined that the steering rack had failed and needed to be replaced. The vehicle was repaired. The manufacturer was notified of the failure by phone. The failure mileage was approximately 39,900.

Sometime around Dec 2025 I noticed the headlights would flicker from time to time producing inconsistent and unsatisfactory illumination in front the vehicle and at times causing a blinding effect to oncoming drivers. The vehicle was taken to the Mazda dealership where they loaded some software in an attempted fix and stated that if that didn’t fix the problem, they would have to order the headlight switch and I would need to reschedule the vehicle back for the replacement. It took a few more months before I noticed the problem wasn’t fix. At that time I was getting ready to take the vehicle back to a Mazda dealership for some unrelated work, so I added that to the list of things to be addressed at the dealership during that visit. Before my scheduled appointment, I was able to determine that the problem only occurred while it was raining. At the dealership they mentioned that this problem had now been reported by others and was determined to be the result of water running off the front of the hood onto and down the front of the headlights. The fix was to install some “eyelids” to channel the water away from the headlights but I needed to reschedule a visit due to parts not being on hand at this time. I rescheduled the visit and had the suggested fix complied with, only to find out during the next rain fall that it only helped a little with the flickering but that the problem still existed. I mention this to the dealership to which they responded that they have done all that Mazda recommended and that there was nothing else they could do. Several months later I took the vehicle back to the dealership for another unrelated issue and to have the headlight problem reinvestigated for a possible permanent fix to which I was informed that there was no new info on this issue and that Mazda had done all that they could do at this point.

I am experiencing the intermittent sticky steering defect on the highway. It begins as a binding sensation during micro-corrections at high speeds, and then the steering remains notched and heavy for the rest of the drive at lower speeds. It doesn’t happen 100% of the time. I need to be driving for a little while on the highway before it starts. I took it back to dealership but they couldn’t get it to do the same thing but they did add grease to a part of the steering. It seemed ok for a few weeks, but it is now back again. I am going to call the dealership back because they advised to let them know if it does start happening again.

At high speeds, when turning around a bend the steering wheel gets sticky and will get stuck and then suddenly move again. This can happen 2-3 times as the wheel is turned around a bend.
