2025 MAZDA CX-70 Lane Departure Problems

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.

[XXX]: While traveling eastbound and westbound on [XXX] between La Crosse, WI and La Crescent, MN, the right side BSM mirror warning illuminated several time with NO vehicles in blind spot (no video captured). [XXX]: while entering La Crescent, MN from [XXX] southbound, the right side BSM mirror warning illuminated with NO vehicle in blind spot. Video was captured on cellphone if requested, 277MB in MP4 format. INFORMATION REDACTED PURSUANT TO THE FREEDOM OF INFORMATION ACT (FOIA), 5 U.S.C. 552(B)(6)

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.

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.

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.

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.

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.

The i-Active safety sense system in the vehicle shuts off in moderate rain. I believe it to be far too sensitive. the system complains that it cannot see the road and vehicles with the camera system. Inclement weather is when I need the i-Active safety sense the more. Earlier this week on my way to work, it disabled itself in very light rainy conditions. I had no trouble seeing but the system did. When this happens cruise control is completely disabled. I reported this to the dealer but they shrugged their shoulders. No one seems to test these systems in less than perfect weather. There are warning on the dash saying that i-Active safety sense is disabled.

Often, when I drive on highways, I find that the blind spot indicator turns on when there are no cars around. It creates unnecessary panic and confusion during long road trips, increasing driver's stress and anxiety.

Blind spot warning light keep comes on even if there is no vehicles around. It was constantly coming on and off while I was driving for about an hour and half.
