2025 Mazda CX-70 driver assistance problems

Randomly, the rear blind spot warning will go off even when there is nothing there while driving. It is typically always the right rear blind spot. It has done this for over 9 months now. I contacted the dealer but they ignored me.

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 took the car into a Mazda dealer in [XXX] ,FINDLAY MAZDA they told us that the system is malfunctioning but the software fix is not yet available from the manufacturer Mazda. We were told to wait for contact from Mazda to get the update . About two moths later we backed into a mailbox at slow speed and received no alert . This collision caused $600 damage to the right tail light . This incident prompted me to call Mazda customer experience to get our software update expedited. They resisted and continued with the unavailable narrative .I insisted and demanded a fix as this was a safety feature that is now an unsafe condition and also it is a very expensive feature on this car that we paid for and have not had the use of for several month to that point . A service appointment was arranged at Alan Webb Mazda in [XXX] . By the time of the appointment there were two other service recalls that needed to be accomplished on the vehicle so I approved that works also but the repair of the collision avoidance system was my primary concern and also Mazda had agreed to replace the tail light if in fact the system had malfunctioned . The next day the vehicle was ready for pickup (July30, 2026). When the vehicle was picked up at the service dept. I was told that there were no problems with the collision avoidance system . As of Aug 1,2026 the system is still malfunctioning in the same way as the two previous complaints . I believe they are hiding the truth about vehicle safety features.

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.

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

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 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.

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.
