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 t…
Phantom Blind Spot Monitoring occurred while driving 70-73mph. Right driver side blind spot turns on for almost 5 minutes with no other vehicles around. Switching lanes causes lane departure warning system to activate.
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 …
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 vehicleâs 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 aft…
Blind Spot Monitor detecting phantom objects at highway speeds with no other vehicles around. Speeds between 69-75mph. Right Passenger side blind spot light turns for up to 20 seconds, turns off, then turns on again.
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, the panoramic sunroof suddenly exploded outward without any impact from road debris or another object. The glass shattered unexpectedly, creating a safety hazard from falling glass and the sudden loud noise. I believe the failure may have been caused by pressure inside the cabin or a defect in the sunroof glass or its installation. There were no visible signs that the vehicle struck anything before the glass shattered.
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 20…

DESCRIPTION Some CX-70 and CX-90 PHEV vehicles may fail to start (enter READY mode) in cold weather, but the vehicle can often be started successfully on the next attempt. This may occur when leakage current between connector terminals causes the MAIN Relay to be falsely detected as ON. As a result, the Battery ECU may incorrectly determine the relay status, preventing READY mode activation and resulting in a no-start condition. One or more of the following DTCs may be stored: P0AB9, U0100, U0110, and U0115 and multiple warning lights may also turn on. This is caused by corrosion of the connec

Source: NHTSA Office of Defects Investigation public data (complaints, manufacturer communications, investigations), model years 2010 and later. Had a safety problem? Report it to NHTSA.
In complaints filed with NHTSA for model years 2025–2026, owners most often name: lane departure, forward collision avoidance, power train. 54 complaints are on record.
No. A complaint is an unverified report from an owner. A technical service bulletin (TSB) is the manufacturer telling dealers how to fix a known issue; it is not a safety recall and is usually covered only under warranty. A recall is a formal safety action, and its repair is free.
File a vehicle safety complaint at NHTSA.gov. NHTSA reads every report, and patterns of complaints are what open defect investigations and, eventually, recalls.
