What 46 owners told NHTSA about the 2025 Mazda Cx-70

This happens often. On a trip to Florida of 1200 miles, it happened 12 times each way. After being slowed in the right lane by a car in front driving slower tan my set cruise speed, I signal and move to an empty (in front of me) left lane. Instead of accelerating to resume my set cruise speed, the car decelerates abruptly by as much as 10 mph. If a car is following me and most logically is expecting me to accelerate after moving to the left lane, that car's driver is surprised and risks rear ending me. I took the car in to service this issue. Mazda has a Service Alert (SA-007/24. The conclusion of the SA is basically it is what it is. I think that this is a serious safety issue. I have a 2016 Subaru Outback with adaptive cruise control and it never does this. Maxda's system is deficient. The NHTSB should analyze and compare adaptive cruise control systems.

There have been several false blind spot monitoring alerts since I received vehicle. It seems to get worse with time. Now on freeway trips it’s almost constant leaving no trust with alerts

While driving at a speed just under 45 mph, my Mazda CX-70 suddenly displayed and chimed “Hybrid System Malfunction. Have Vehicle Inspected.“. This warning startled me because I am familiar with issues since I had briefly owned a CX-90 PHEV the first year this model came out and it had the same exact problem. I discovered that this issue carries serious safety concerns and ended up convincing the dealer to swap the vehicle for a CX-90 inline 6 gas only model after hours of pleading. I ended up signing up for another lease a couple of years later with this current CX-70 PHEV, as I was told that the “bugs” have pretty much been worked out so I would give it another try. This warning continued to stay on as I drove for a few minutes so I immediately took the car straight to the Mazda dealership service department where it was kept 24 hours. The dealer said that the issue resolved itself - something to do with not driving the vehicle interchangeably enough between gas and EV mode. The photo was taken once I slowed down to stop at an intersection since it took me 15 minutes to drive to the dealer.

This has occurred numerous times. Using the adaptive cruise control, the vehicle decelerates as I approach a slower moving vehicle. That is what it should do. When I move from the right lane to the open left lane, instead of accelerating back to the set cruise speed, the car decelerates as much as 10 mph before finally regaining its mind and accelerating to the set speed. I have had cars following me that are expecting my car to accelerate that are surprised that the car decelerates. This happens on straight roads with no car ahead of me in the left lane.

The steering wheel on the car will often get stuck and not return to the normal position when turning. Happens at low speeds on on/off ramps and at interstate speeds when the road slightly shifts. “Jerking” the steering wheel is often required to get the car to drive straight and return to normal driving position.

The vehicle has engaged the automatic braking feature multiple times while in a parking garage and when in the middle of a four-way stop despite there being no cross traffic or moving vehicles around my vehicle. In two instances, there was a vehicle behind mine that the breaking could have led to me being rear-ended and in the case of the four-way stop, there were other vehicles waiting to cross that could have hit me from behind or on the side. The vehicle was taken to the local Mazda dealership who had the vehicle for approximately 3 weeks trying to identify a fix and was subsequently told to pick up the vehicle without a fix being performed. I was informed after that time that Mazda was aware of this being an issue for multiple owners but did not have a solution to resolve it. I was told to wait to be contracted at some point in the future about an identified repair or recall. This is a serious safety issue that could lead to a collision and Mazda has stated that they do not have a solution to the problem.

The contact owns a 2025 Mazda CX-70. The contact stated that while driving on several occasions at various speeds with the Lane Keep Assist feature deactivated, the steering wheel jerked to the left. The vehicle was towed to a dealer, and the failure was being investigated. The vehicle was not yet repaired. The manufacturer was notified of the failure, and a complaint was filed. The failure mileage was approximately 19,000.

Lane assist system acts on it's own and attempts to override my input. It can be very jarring especially at high speeds. I notice the issue mostly when I'm on the highway/freeway and attempting to lane change or take an exit ramp. The system trys to correct my steering and I have to briefly fight against it to maintain control.

I purchased a Certified Pre-Owned Mazda CX-70 that exhibits intermittent and unpredictable steering behavior, creating a significant safety concern. The steering will intermittently stiffen and then pull the vehicle left or right without driver input, at times toward oncoming traffic or the breakdown lane, requiring immediate correction. On straight roads, the vehicle does not consistently track and will drift unpredictably. When driving over minor road variations (such as small bumps or frost heaves), the steering wheel may jerk suddenly in the opposite direction. The vehicle also intermittently behaves as though lane-keeping assistance is active—auto-correcting relative to lane lines—despite all lane assist features being turned off. In multiple instances, the vehicle has tracked erratically along lane lines or navigated slight curves without driver input. The issue occurs unpredictably but is more pronounced on rural or uneven roads and during initial driving, though it can persist on highways as well. The issue caused several near miss accidents-twice it sent my vehicle careening into oncoming traffic; another time it tried to drive me back toward a pedestrian I was driving around intentionally. Driver has to be at constant heightened attention to avoid accident. Multiple repair attempts were made, including replacement of the steering column. The condition temporarily improved but returned and worsened. During the final repair attempt, dealership foreman, master technicians, and manufacturer technical support were involved, and the condition was ultimately deemed a “characteristic” with no repair available. The vehicle remains unrepaired and unsafe to operate. The dealer is refusing to supply the customer with any details of the repair order and diagnostic work that was done. The manufacturer has agreed to repurchase the vehicle under lemon law, confirming the defect could not be resolved.

Vehicle has transmission related issues. Delayed response/hesitation when accelerating from a stop or after decelerating. Delayed torque sometimes few seconds off. Others reported dealer has had software updates however issues remain which is a safety concern when on the road. Suspension frond end mild early on 500 miles or so however has gotten louder at 12k miles. Vehicle seems to be to heavy for the type of suspension used or defective suspensions parts. Many complaints filed on the front end noise however Mazda has not announced recalls. Stock tires Toyo All Weather are a safety hazard. Slippery in the rain and snow. These are not safe for a vehicle this size. Doors do not have insulation, road debris comes inside and all the cold air or wind makes it in through the side and bottom doors.

I have put on over 20,000 miles since I purchased new in September 2024. The entire time of ownership, I have dealt with false blind spot warnings. With a clean car/clean sensors, it doesn't matter the time of day/night... when driving at highway speeds, the right rear blind spot warning comes on intermittently even when driving in the right lane of interstate with only the shoulder of the interstate next to me and no other obstructions. When this happens while in the passing lane and believing there is nobody next to me and I put on the blinker and try to switch lanes.... it alarms me saying there is something in my blindspot. These are false readings, that make this "safety feature" a safety concern. Sometimes, the car even tries to pull me back in my current lane even though there is nothing in sight in the lane I'm trying to switch to. The I have had the car to the dealership approximately 4 times for this ongoing issue and they claim they are unable to replicate the problem. I have read numerous other complaints reporting the same issue, and Mazda has not developed a fix to date.

On the morning of January 28, 2026 I arrived to work and came to a complete stop in my works parking garage. I used my key card to raise the gate. Once the gate was fully raised I pressed the accelerator to drive up the ramp. Shortly after accelerating, my engine revved really loud and high rate, then my car automatically increased speed. I immediately pressed the brake pedal but it didn’t stop. It continued accelerating at a speed not controlled by me with my brakes not engaging even though I was pressing the brake as hard as could. I estimate I travel about 100’ with no control of the gas or brake. It lasted about 15-20 seconds. If a car were in front of me at that time, I would have crashed into them because I could not stop the car. I immediately called Davis Moore Mazda. I had the vehicle towed there because I didn’t feel safe driving it. Information from my cars computer program was sent to Mazda. Mazda didn’t see any issues and their diagnosis was a foot was likely on the accelerator causing the acceleration. The general manager called me to discuss. He said the only thing that registered was acceleration. I asked does the computer show my attempt to brake (stop) the car. His response was the computer wouldn’t read that because that was a normal driving process that wouldn’t be recorded. I asked why the acceleration would trigger an alert in the computer, since acceleration is also a normal driving process. He then said the computer picked it up because it accelerated quickly. There were no warnings present prior to this issue.

At highway speeds (>60 mph), the blind spot detection on the passenger side will alert that a car is present in the vehicles blind spot when no car is present. This will happen intermittently and will continue even if I begin the lane change process, it will continue to alert that the car is there. Additionally, and less frequently, the forward collision detection system will identify a car is in front of the vehicle causing a sudden slow down in the adaptive cruise control or an alert.

Incident details: While driving under winter road conditions, the vehicle experienced a brief slide. During this slide, the vehicle lightly scrapped a curb, leaving a minor mark on the wheel. Despite this, the airbags deployed unexpectedly. There was no collision, no rollover, and no other object was struck, and there is no visible exterior damage to the vehicle. ________________________________________ What component or system failed or malfunctioned, and is it available for inspection upon request? The suspected malfunction involves the airbag system, potentially including the airbag control module (ACM), crash sensors, or the electronic stability control (ESC) system. The airbags deployed without a qualifying collision or impact. The vehicle is being preserved and has not been repaired, and it is available for inspection upon request, with event data recorder (EDR) data preserved and available for retrieval.________________________________________ ________________________________________ Has the problem been reproduced or confirmed by a dealer or independent service center? No. A Mazda-authorized dealer (Mazda of Salem, Oregon) declined to accept the vehicle, stating that they do not perform post–airbag deployment investigations.

I had my car only for 4 months, but the windshield glass is broken when the car was parked on my driveway couple days ago I usually only drive my cars during weekends so the windshield glass broke without any forcing. I was asked to bring to Mazda dealer, the 495 Mazdas at Lowell MA. The technician couldn’t find any cause leading to broken windshield. I took the car to safelite shop. The inspection report is same and believe it is most likely due to quality issue. However Mazda service was not willing to repair. Very poor and disappointing customer support!

Multiple times when there is a car on my left or right blind spot and I am merging into their lane the warning does not go off and has caused me to nearly collide with the cars without my intervention. The warnings only work if the cars are behind me not adjacently. This is misleading because the , i-ACTIVSENSE says its 360 degrees, but its not alerting or warning to cars to my left or right. I do not trust the safety systems.

with 500 miles on the car i heard a faint rattle around the front driver tire when driving slow on rough roads and slow over small bumps. Now with 3600 miles on the car the noise is much louder and something sounds very lose. Fear failure of suspension will cause an accident. TSB was released on CX-70 for vehicles produced prior to my vehicles production date. Fear the issue has not been resolved and my safety and my vehicle are at risk.

Safety Issue: Gear box unexpectedly disengaged while driving at highway speeds, between 60 and 70 mph. This occurred without warning and under normal road and operating conditions. Driver was unable to accelerate or decelerate vehicle. Driver did not have forward propulsion of vehicle at time of incidents (this happened more than once), and therefore, this is an extreme safety issue.
