2024 MAZDA CX-90 Forward Collision Avoidance Warnings Problems

We have had Multiple I-Sense(safety system).It will shutdown whwnever it feels like it no matter the weather.We have had at Mazda 7 times and they have applied several programming updates withouit success. We have also have Apple wireless airplay for directions and phone failure 100's of times and have had it Mazda fro the same 7 times to fix to no avail

On multiple occasions the vehicle has falsely detected collisions and suddenly braked while on highway leading to serious safety issues. On other occasions, while changing the lanes with blinkers on, the vehicle suddenly steered back into the original lane and triggered a collision warning even though there was no vehicle/obstacle nearby. This created a serious risk of collision. Even at slow speeds, the vehicle inaccurately triggers a collision warning creating unsafe driving conditions. This frequently happens when we are driving the vehicle in the parking garage, even in absence of moving vehicles nearby. The mild hybrid power train system had issue leading to hybrid system malfunction and iSTOP malfunction. This finally led to hybrid battery failure and the vehicle remaining out of service for over a month. Apple Carplay disconnects erratically creating hazardous condition especially when we are using Carplay for navigation. Such a disconnection requires the driver to suddenly...

I was parking the car at a low speed (2mph) when it suddenly accelerated with a great speed, jumped the curb in front and moved forward and up a small hill. The car collided with a tree before I was able to stop it. All ADAS features were activated in the car and no alarms sounded prior or during the event, which lasted between 1-2 seconds. The vehicle was inspected by Mazda and deemed safe to continue to operate. The dealer did not find a cause for the malfunction and suggested external influence. The inspection took about 3hrs, which included addressing multiple recalls on the vehicle. At time of incident I have owned the car for about two months and did not experience similar issues, however others did according to my web search. I found reports on popular forums describing sudden acceleration of Mazda CX-90 vehicles.

An ultrasonic sensor located in the right front grill area was determined to have failed producing the following message on the dash display: I-Activsense Temporarily Disabled. Ultrasonic Sensor Obscured. Drive Safely. This message initially appeared at approximately the 1500 mile mark of service and was documented when the vehicle was brought in for routine maintenance to Fort Myers Mazda at mile mark 3583 on 3/12/24. It is my position that safety equipment should be reasonably durable and reliable which is clearly not the case in this situation. There is a small pin sized dimple in the sensor lens. The sensor is currently available for inspection. It is further the position of Fort Myers Mazda that this sensor is not covered by the Manufacturer’s warranty due to component damage.

When using the adaptive cruise control on a multi-lane highway the system will detect trucks/larger vehicles moving into your lane on a slight curve when they are not. The system will apply brakes to avoid a collision. The first time this happened there was no vehicle moving into my lane but there was an 18-wheeler behind me that wasn't expecting my vehicle to brake and they almost rear-ended me. This happened several other times before I understood the problem and turned the system off. I have reported this to my dealer and they stated the problem couldn't be replicated. This has been reported multiple times by other CX-90 drivers on this site and Mazda will get someone injured or killed if this is not fixed. If you drive a CX-90 do not use the cruise control until this is addressed by Mazda.
