   Within 100 days of purchasing the CX70 new ,we noticed that the collision avoidance system was malfunctioning . It would alert when no car was near us . It did not alert every time a car was actually in our right blind spot or moving through our right blind spot . The malfunctions were random and happened in a variation of conditions and driving situations . We began to mistrust the system and continually disregarded many of its alerts . The old boy who cried Wolf sinerio.We…

   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…

   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.

   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…

   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

   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…

   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…

   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…

    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…

    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…
