Hybrid battery failed causing electrical issues. - Fix in October 2024. During this time Service repair for the recall related to the power steering. Car became jerky and would lose the ability to hold turns. Took to mazda and told there was a gear housing need to be replaced. Was quoted at 4000 for the repair due to car having 49000. Mazda customer service stepped in and dropped the price in half. Eventually cover the majority of the cost as we reported this as a safety issue and it only camp up after the recall was performed for the power steering and the suspension was fixed. In the service report, Technician stated that the steering has fuse to the sway bar. I am now very concerned the sway bar is unsafe. Mazda did not comment on this when I ask. It appears as the fix one thing more continue to break. with The issues the lane assist continues to have issues seems to struggle with alignment issues. Car was with Mazda for 7 weeks during the 1st year of owning it. I am also concerned with some of the finding as I look at them with details pertaining to original purchase and miles being reported on our documents. Living in Kentucky the Lemon law does help with providing any sort of real action plans on CPO. Break have been squeaky causing uneven feedback. This issue has worsened over time. Car was purchased CPO - in April of 2025.
2024 Mazda CX-90 driver assistance complaints
Page 2 of 3: complaints 11 to 40 of 53, newest first, as owners wrote them.
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 parking cameras will fail to activate unexpectedly when backing up or if the cameras are activated using the manual button. The issue is similar to what is described in Mazda Safety Recall 6223J: "Images of the front-, side-, and rear-view cameras may flicker and, in some cases, may no longer appear on the center display monitor. Improper processing logic in the view monitor camera control module may cause image deterioration. Loss of front-, side-, and rear-view camera images when in reverse and/or using the 360-degree monitor can increase the risk of a crash. There is no warning preceding the occurrence of this defect." I brought this issue to the dealer and Mazda USA but it remains a problem. The issue most recently occured on April 15, 2026, but has happened multiple times in the past.
Sticky steering overactive lane assist
Stick steering wheel. Excessive force need to steer while making a turn.
At highway speeds, even with lane keeping assist disabled/turned off, if the ADAS is turned on LKA seems to remain active. Steering effort is unpredictable making it difficult to maintain a line through the corner. Effort will suddenly decrease resulting in oversteer. This is particularly dangerous when next to other cars, guardrails, barriers and the like. The behavior is greatly reduced with all ADAS off. This is largely repeatable over the last 18 mos/24,000 miles.
I am reporting a serious steering safety issue. I was told a steering recall had already been fixed before purchase. About four months later, the steering wheel began locking or strongly resisting movement while driving on curvy roads at speeds over 50 mph. When this happens, the wheel does not return to center and requires force to correct, creating a loss of steering control. I took the vehicle to Passport Mazda in Maryland on January 2, 2026. The dealer stated the entire steering wheel panel needs replacement and the part is backordered until March 2026. This is a dangerous defect in a recently recalled system and needs investigation.
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.
We have had Multiple I-Sense(safety system).It will shutdown whwnever it feels like it no matter the weather.We have had at Mazda 7 times and they have applied several programming updates withouit success. We have also have Apple wireless airplay for directions and phone failure 100's of times and have had it Mazda fro the same 7 times to fix to no avail
On multiple occasions the vehicle has falsely detected collisions and suddenly braked while on highway leading to serious safety issues. On other occasions, while changing the lanes with blinkers on, the vehicle suddenly steered back into the original lane and triggered a collision warning even though there was no vehicle/obstacle nearby. This created a serious risk of collision. Even at slow speeds, the vehicle inaccurately triggers a collision warning creating unsafe driving conditions. This frequently happens when we are driving the vehicle in the parking garage, even in absence of moving vehicles nearby. The mild hybrid power train system had issue leading to hybrid system malfunction and iSTOP malfunction. This finally led to hybrid battery failure and the vehicle remaining out of service for over a month. Apple Carplay disconnects erratically creating hazardous condition especially when we are using Carplay for navigation. Such a disconnection requires the driver to suddenly reach over to the phone and input driving directions in the phone again. This is especially dangerous in city driving conditions needing frequent turns.
Same problem as Recall no. 24V349000, which does not apply to my vehicle because it is newer than the manufacturer build range. 100% repeatable.
I was parking the car at a low speed (2mph) when it suddenly accelerated with a great speed, jumped the curb in front and moved forward and up a small hill. The car collided with a tree before I was able to stop it. All ADAS features were activated in the car and no alarms sounded prior or during the event, which lasted between 1-2 seconds. The vehicle was inspected by Mazda and deemed safe to continue to operate. The dealer did not find a cause for the malfunction and suggested external influence. The inspection took about 3hrs, which included addressing multiple recalls on the vehicle. At time of incident I have owned the car for about two months and did not experience similar issues, however others did according to my web search. I found reports on popular forums describing sudden acceleration of Mazda CX-90 vehicles.
Driving between 30 - 40 mph on a strait road with no obstacles in front or along side the emergency braking engaged for no apparent reason at all! This has been an ongoing issue with this vehicle, there was a recall to update the software but the problem still exists intermittently! This is a very serious safety concern to have an all of a sudden unexpected hard braking action when the road is free and clear!
Going down the road with cruise control I have been used to it dropping a little bit in curves but today and car behind me had to slam on there brakes because the cruise control in a small curve dropped me down immediately from 60 to 45 jerk and all. If the driver behind me had not been paying attention they would have slammed into me since we were both going 60 no other cars around just a small curve on a straight road
The contact owned a 2024 Mazda CX-90. The contact stated that while driving at various speeds, a clunking noise would emit from underneath the engine compartment. The vehicle was taken to a dealer where it was diagnosed that the control arm had failed. The vehicle had been repaired. The contact stated 3 days later while driving approximately 35 -45 MPH, the brake pedal was depressed but failed to respond. In addition, the vehicle was attempted to be veered to the left or right and it failed to drive in either direction. As a result, the vehicle crashed into the rear-ended of the vehicle in front. The air bags deployed. The vehicle was towed and deemed totaled. The contact stated that the other party's vehicle was damaged and towed away. A police report was filed. The contact sustained a left leg, right arm, shoulder, wrist, and neck injuries that required medical attention via hospital. The contact's wife was seated in the passenger seat at the time of the crash and sustained injuries to the right shoulder, wrist, and both the left and right foot's toes that required medical attention via hospital. The contact was unsure of any injuries to the occupants of the other vehicle. A dealer was contacted. The vehicle was not diagnosed or repaired. The contact received notification of the federal safety agency Campaign Number: 24V349000 (Forward Collision Avoidance) however, the part to do the recall repair was unavailable. The contact stated that the manufacturer exceeded a reasonable amount of time for the recall repair. The manufacturer had been made aware of the failure and opened a case. The failure mileage was 23,209. VIN tool confirms parts not available.
An ultrasonic sensor located in the right front grill area was determined to have failed producing the following message on the dash display: I-Activsense Temporarily Disabled. Ultrasonic Sensor Obscured. Drive Safely. This message initially appeared at approximately the 1500 mile mark of service and was documented when the vehicle was brought in for routine maintenance to Fort Myers Mazda at mile mark 3583 on 3/12/24. It is my position that safety equipment should be reasonably durable and reliable which is clearly not the case in this situation. There is a small pin sized dimple in the sensor lens. The sensor is currently available for inspection. It is further the position of Fort Myers Mazda that this sensor is not covered by the Manufacturer’s warranty due to component damage.
The contact owns a 2024 Mazda CX-90. The contact stated while driving the same day the vehicle was purchased, the message "Telematics Malfunction" was displayed. The vehicle was taken to the local dealer, where the message was cleared; however, the failure persisted. Additionally, the contact became aware that the VIN was included in the federal safety agency Campaign Number: 23V718000 (Back Over Prevention, Forward Collision Avoidance, Lane Departure). The contact stated that while driving, the images of the front-view, side-view, and rear-view cameras failed to appear on the center display intermittently. The vehicle was taken to the dealer, where it was diagnosed, and the dealer determined that the view monitor control module software needed to be updated; however, the part to do the recall repair was not yet available. The vehicle was not repaired. The contact stated that the manufacturer had exceeded a reasonable amount of time for the recall repair. The manufacturer was not made aware of the failure. The failure mileage was approximately 8,500. Parts distribution disconnect.
The “360 View Camera” image periodically goes blank, providing no image, just a blank screen with the colored lines showing vehicle and wheel direction. So when the car is put in reverse or forward, no image of the surroundings are visible. This will not resolve until the vehicle is turned off for an extended period. (An immediate restarting of the car will not resolve.) This car has had the other camera recall addressed and another camera TSB addressed. The issue continues to occur at random, unpredictable times. It has perhaps occurred 10-11 times.
The lane assist safety feature stops working. The car will allow drifting across well-marked lanes, despite being a clean car and a clear weather day. The car will not attempt to keep the car in the lane. The events are unpredictable. I have checked the settings when it has happened and they all appear to be the same - the lane assist and related boxes remain checked, etc. After turning off the vehicle for an hour or two, the system seems to reset and work again. This has happened twice that I know if, but could have happened at other times that I did not notice.
I have raised case [XXX] [XXX] [XXX] ] with Mazda regarding my 2024 CX90 where there's a suspension and emergency automatic forward Collison breaking since I purchased the car and now this steering issue safety recall. They are not replacing or buying back. I'm feeling unsafe and fear to drive as if this malfunction car leads to accident. Please assist. INFORMATION REDACTED PURSUANT TO THE FREEDOM OF INFORMATION ACT (FOIA), 5 U.S.C. 552(B)(6)
When driving on the highway next to a large truck or semi and on a curve, the adaptive cruise control thinks that there’s a vehicle in front of you and slams on the brakes. This has happened a few times with my vehicle. Thankfully, there were no vehicles immediately behind me, or the results could’ve been tragic.
During cruise control engagement when passing a larger vehicle the system sometimes will execute aggressive braking potentially causing an accident with a vehicle following behind. Have to be ready to disengage cruise control during all situations with other vehicles in proximity. It will always perform the aggressive braking maneuver when passing a semi-truck on a curved highway.
Passenger side, side view mirror will intermittently turn all the way in and down. This makes it impossible to see traffic on your side. Once it turns in, it is stuck and you need to get out of the car to physical move it so the motor will adjust it again. This can happen at anytime and has happen at least 10 times since we've purchased the car on 12/29/2023
In tighter corners the car coasts/brakes unnecessarily while cruise is on. Seems like a safety feature possibly or a malfunction as I haven't had that on any other cruise controls on other vehicles. Then after the corner it accelerates. I find very annoying. If this is considered a safety feature then ok but it is way to sensitive currently and needs an update.
When using the adaptive cruise control on a multi-lane highway the system will detect trucks/larger vehicles moving into your lane on a slight curve when they are not. The system will apply brakes to avoid a collision. The first time this happened there was no vehicle moving into my lane but there was an 18-wheeler behind me that wasn't expecting my vehicle to brake and they almost rear-ended me. This happened several other times before I understood the problem and turned the system off. I have reported this to my dealer and they stated the problem couldn't be replicated. This has been reported multiple times by other CX-90 drivers on this site and Mazda will get someone injured or killed if this is not fixed. If you drive a CX-90 do not use the cruise control until this is addressed by Mazda.
When using adaptive cruise control and you are driving on a curve, if there is a vehicle, guard rail or jersey barrier in the next lane or on the side of the road, the vehicle will brake hard thinking there’s something in front of it. It has even happened when there was a hillside next to the road. This is very dangerous on a high speed highway. It can slow down from 75 mph to 45 mph in a very short amount of time.
When going into curves on interstate, car thinks its gonna hit something and slams on the brakes when cruise control is engages. When passing a semi (semi slow lane, passing in passing lane), vehicle detects something in front of it and slams on the brakes. Does this on straight stretches. Slows down extremely fast to mabye 40 mph, then floors it once it thinks the "obstacle" has disappeared and speeds back up to the set speed as fast as it can. Sometimes does it when no othwr vehicles near it on straight stretchss of highway. This is gonna cause accidens. I don't trust the adaptive cruise control feature because it does this. This isn't weather or light related. Does it all the time.
When adaptive cruise control is engaged, and travelling in the left lane of a multilane highway, automatic braking frequently activates when there is a vehicle ahead in the right lane (especially, but not always, a truck) but no hazard in the lane directly ahead.
When a large object like 18wheeler is in right lane and you are in left lane the car thinks it is in your way and the vehicle brakes hard. Very dangerous. Has happened numerous times.
While using the radar cruise control, the vehicle will aggressively apply braking pressure, without warning and risk losing control of the vehicle. The risk of being rear ended is frightening at highway speeds. This usually happens through turns, and the Mazda mistakes vehicles in opposite lanes as being in the same lane. This has occurred multiple times with different people.
