SERVICE BRAKES, ENGINE, UNKNOWN OR OTHER
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.

LANE DEPARTURE: BLIND SPOT DETECTION, FORWARD COLLISION AVOIDANCE: WARNINGS
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.

AIR BAGS
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

VISIBILITY/WIPER
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!

LANE DEPARTURE: BLIND SPOT DETECTION, BACK OVER PREVENTION: REARVIEW SYSTEM BRAKING
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.

SUSPENSION
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.

UNKNOWN OR OTHER, POWER TRAIN
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.

STEERING, LANE DEPARTURE: ASSIST, LANE DEPARTURE: WARNING
While traveling eastbound on GA-20, I signaled to change lanes with my hands in the 9 and 3 position. I don't hold the wheel in a death grip like some people do, as I am confident with my vehicle and my skills. As I am changing lanes at 62 mph the car jerked the wheel to the right while flashing a warning that I need to hold the wheel. This has happened multiple times even though I am in complete control of the vehicle and very comfortable with my hand position. The car should NEVER jerk the wheel like that unexpectedly. I have lane departure turned off for this reason.

FORWARD COLLISION AVOIDANCE: WARNINGS, LANE DEPARTURE: BLIND SPOT DETECTION, FUEL/PROPULSION SYSTEM
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.

ENGINE, POWER TRAIN
After starting the vehicle and driving it for a short distance, I forgot to disable the engine start/stop function. When the engine shut down, I pressed the button to disable it as I loathe this feature. The button would not respond, resulting in the engine repeatedly shutting down during coasting events and limiting the functionality of my AC. I tried multiple times during my 45-minute drive to disable it, but was unable to. I shut the vehicle off and restarted it when I was safely stopped. The system worked as intended after this action. I have never had a car with so many technology bugs and electronic safety system issues as this one.

LANE DEPARTURE: ASSIST, LANE DEPARTURE: WARNING
While attempting to change lanes on I-75 southbound, one lane to the left of my current position, I was enforced and the steering wheel pulled back to the right. I was navigating a right-hand curve on the interstate and moving past slower traffic at 81 mph. My turn signal was activated, the lane departure system deactivated, and the signal was still flashing as the lane change was executed. The turn signal should suspend enforcement as well as the system being deactivated. Both interlocks failed to operate. No other vehicles in the area would've contributed to this event. The lane departure "off" warning light was on the dash, indicating that the system was not operational. I was not firmly holding the wheel and allowing it to glide effortlessly through the lane change to execute my plan when it jerked back to the right.

FORWARD COLLISION AVOIDANCE: AUTOMATIC EMERGENCY BRAKING
I was operating the motor vehicle at roughly 60 mph on a two-lane divided highway around 830AM. I was driving toward the sunrise to the east and passed under a highway overpass. As I cleared the overpass from the shade back into the sun, the vehicle flashed a collision warning on the windshield and immediately applied aggressive braking for no reason. No other cars were in the area around me at the time of the incident. Had someone been following me too closely, this would have likely resulted in a rear-end collision. Safety system malfunctions are frequent and unexpected. It is always something, and this isn't the only time it has happened. It has simply annoyed me enough to cause me to submit a report.

FORWARD COLLISION AVOIDANCE: ADAPTIVE CRUISE CONTROL, FORWARD COLLISION AVOIDANCE: AUTOMATIC EMERGENCY BRAKING, LANE DEPARTURE: BLIND SPOT DETECTION
On multiple occasions I have had driver assistance system failures with the most recent occurring this past Saturday 8/2/25, which I have on dashcam. In this incident, I had adaptive cruise control set to short following distance. I had about 5 or 6 car lengths in front of me at highway speed and the lead car was far enough ahead that the car was not showing it on the interactive display. Another car changed lanes from the right to left in front of me right behind the lead vehicle. The car that changed lanes was not detected by the vehicle even though it was right in front of me. I was approaching the vehicle at a higher rate of speed and the car never attempted to slow eventually requiring me to depress the brake to cancel the cruise as the car was not responding to the fact that I was now right behind the car and had to brake to avoid a collision. On a separate incident a month or so ago, I was entering a center turn lane, waiting to turn into a gas station which required crossing of 2 lanes of traffic in the opposite direction. As I was entering the center lane with my signal on, the car detected the opposing traffic and slammed on the breaks nearly causing me to get rear-ended by the traffic behind me that expected me to enter the turn lane at the rate of speed I was going. Routinely, the car fails to detect vehicles in the blind spot. I can approach, pass, and clear a vehicle on the left (vehicle to my right) and the car will never detect that a car was there in the first place. Additionally, if a car is detected and then stays in the blind spot long enough, the car loses it and thinks the car is no longer in the blind spot.

LANE DEPARTURE: WARNING, LANE DEPARTURE: ASSIST
Blind spot monitoring at highway speeds randomly triggers when nothing is there. Due to this, car fights lane changes due to collision avoidance system if you try to change lanes when it thinks something is there when it’s not.
