2025 Mazda CX-70 Forward collision avoidance Problems

“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. …”

“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.”

“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. …”

“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. …”

“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. …”
