2025 Mazda CX-70 Problems

Vehicle Information I am reporting multiple persistent safety-related defects in my 2025 Mazda CX-70 that began immediately after purchase and continue despite repeated service visits, software updates (including MSP66 on July 9, 2026), and good-faith repair attempts. These defects substantially impair the vehicle’s safety, drivability, reliability, and security. • Warning Lights & Phantom Braking: Brake messages and related warnings on the cluster appeared on the drive home from the dealership shortly after purchase, even with no obstacles present. Intermittent false warnings have continued. • Shifter / Transmission Behavior & Hard Shifting: Intermittently fails to engage Drive after Neutral (especially after car washes). The shifter moves to D but the vehicle remains in Neutral. Notable hard shifting and intermittent poor power acceleration have also been observed. Video evidence provided to dealer. • Door Lock & Latch Failures: Doors intermittently fail to lock or unlock via key fob or interior switches. Doors sometimes do not open when pulling handles. Auto-lock does not always engage. I have observed the vehicle automatically lock (audible sound and folding mirrors) only for it to be found unlocked the next morning. Passengers have been trapped inside on multiple occasions. These issues raise serious entrapment, safety, and theft concerns. • Hybrid System / i-Stop Malfunctions: Repeated MyMazda app alerts for “Hybrid system malfunction. Vehicle would not restart from I-Stop shut down causing me to have to put it back into park and restart the vehicle. • i-Active system failures: The i-Active system occasionally disengages even during clear weather. Dealership states this can sometimes happen due to direct sunlight and sensors? • During a previous discussion with Mazda Customer Care, they stated that they notes a previous power train failure on their end which I was unaware of.

Multiple instances while driving on the highway with cruise control and lane keep assist on - on a bend slight turn the car veered into the other lane across the lane lines - even with other cars present. Additionally, it does not auto steer away from a blind spot collision - had I not noticed the car there would have been an accident.

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.

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.

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.

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.

My cx 70 has extreme brake squealing. This began early on after I purchased this vehicle new from the dealership. I have brought this car to the Mazda dealership that I bought it from three times for this issue.

After fuel gage recall completed, vehicle still doesn’t read fuel level correctly. Sometimes doesn’t show fuel level at all, sometimes, after refueling to a full tank, computer only shows 250 miles of range.

CX-70 routinely has been falsely alerting to an impending crash when no vehicles in front or to the sides. Vehicle routinely does not alert when there is traffic to left or right when merging into a lane. Multiple near accidents when a vehicle was present in blind spot when merging lanes and the safety system failed to steer away or make an alert noise. Vehicle routinely alerts to take over steering wheel even when both hands are on steering wheel. I do not feel confident in the safety systems as they are not executing safety procedures as described in the vehicle manual and appear to be defective. Vehicle fuel gauge consistently under reports the amount of remaining fuel. This causes the gauge cluster to fall to empty faster than it actually should be.

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. As a result, the issue has not yet been reproduced or confirmed by a dealer or independent service center. I contacted Mazda of Hillsboro (Oregon), and the service center manager contacted the Mazda Experience Center on my behalf under case number 00404588. I was informed that the Mazda Experience Center advised them that the case would be closed with no further investigation. I was advised to take the vehicle to a body shop and to file an insurance claim. ________________________________________ Has the vehicle or component been inspected by the manufacturer, police, insurance representatives, or others? Mazda Corporate has been notified of the incident. The vehicle has not yet been inspected by the manufacturer, a dealer, law enforcem

As I was stopped on [XXX] waiting to turn left onto [XXX] , another vehicle struck mine from the rear, at approximately 50mph. The seat belt did not immediately lock, compromising my safety. I slid upward, partially out of the seat belt striking my head on the headliner and the belt caused a large bruise on my upper left arm. Additionally, the air bags did not deploy, but a spray of chemical came out onto me from the dash. The chemical sprayed onto the right side of my neck and collar bone, leaving a burning sensation. A week after this wreck, all the skin that was contacted by the spray, began peeling off, like a sunburn peel does. After this wreck, a warning notice appeared on my dash screen, stating AIRBAG FAILURE, in red lettering. There were no failure notices prior to this wreck. It’s unknown if any inspection of these two failures was done by my insurance adjusters, the manufacturer, the police or a dealership. There has been no known reproduction of these failures I am aware of. The vehicle is expected to be a total loss, but I am still waiting for that determination. The vehicle is still at the repair facility, Caliber Collision in Carbondale, IL, as of 7-1-2025. I have reported these failures to my insurance representative, the manufacturer, the repair facility and the dealership.

While unloading cargo from the rear of my 2025 Mazda CX-70, I activated the power liftgate(key was in pocket ) to close while i was reach back cargo . As the liftgate was closing, it struck me in my head and continued closing instead of stopping or reversing. I had to quickly move out of the way to avoid further injury. The obstacle detection feature did not appear to function as expected. I am concerned this could cause injuries to other owners, especially children or older adults.When I demonstrated my concern to the dealership using a soft pillow ( today when i wen to change oil 7-31-26), the liftgate compressed the pillow before reversing only a few inches. I remain concerned that the obstacle detection system may not provide adequate protection if a person is in the path of the liftgate.

water was leaking from the forward ceiling near interior light control panel. parked the car outdoor overnight, and next morning I started the car and moved slowly, then constant stream of water leaked from the forward ceiling for few seconds.

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.

See attached document for complaint.

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.

See attached document for complaint.

Dealer advised that that the tires needed to be replace, 4/32 front, 5/32 rear. Car only has 12,277 miles, over half of them are freeway and the remainer are mostly country roads. Service department at the dealership said he has seen examples of bald tires ant 10k miles. Service department said they are too soft of a compound for the heavy car. Tires are Falken ZIEX CT60A A/S 275/45 A21. I normally see original tires needing replacement at 30k. The Service rep at Falken said that normal original tires last 30k. My ticket with Falken tire is 2102897918 and I talked to them at 11:30 AM EDT on 9/25/2025.

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!
