VEHICLE SPEED CONTROL, FORWARD COLLISION AVOIDANCE: ADAPTIVE CRUISE CONTROL, FORWARD COLLISION AVOIDANCE: AUTOMATIC EMERGENCY BRAKING
When going into curves on interstate, car thinks its gonna hit something and slams on the brakes when cruise control is engages. When passing a semi (semi slow lane, passing in passing lane), vehicle detects something in front of it and slams on the brakes. Does this on straight stretches. Slows down extremely fast to mabye 40 mph, then floors it once it thinks the "obstacle" has disappeared and speeds back up to the set speed as fast as it can. Sometimes does it when no othwr vehicles near it on straight stretchss of highway. This is gonna cause accidens. I don't trust the adaptive cruise control feature because it does this. This isn't weather or light related. Does it all the time.

FORWARD COLLISION AVOIDANCE: ADAPTIVE CRUISE CONTROL, FORWARD COLLISION AVOIDANCE: AUTOMATIC EMERGENCY BRAKING
When adaptive cruise control is engaged, and travelling in the left lane of a multilane highway, automatic braking frequently activates when there is a vehicle ahead in the right lane (especially, but not always, a truck) but no hazard in the lane directly ahead.

VEHICLE SPEED CONTROL, FORWARD COLLISION AVOIDANCE: ADAPTIVE CRUISE CONTROL
When a large object like 18wheeler is in right lane and you are in left lane the car thinks it is in your way and the vehicle brakes hard. Very dangerous. Has happened numerous times.

VEHICLE SPEED CONTROL, FORWARD COLLISION AVOIDANCE: ADAPTIVE CRUISE CONTROL, FORWARD COLLISION AVOIDANCE: AUTOMATIC EMERGENCY BRAKING
While using the radar cruise control, the vehicle will aggressively apply braking pressure, without warning and risk losing control of the vehicle. The risk of being rear ended is frightening at highway speeds. This usually happens through turns, and the Mazda mistakes vehicles in opposite lanes as being in the same lane. This has occurred multiple times with different people.

FORWARD COLLISION AVOIDANCE: ADAPTIVE CRUISE CONTROL, LANE DEPARTURE: BLIND SPOT DETECTION
Cruise control safety concern: car detects vehicle in front when there isn't and brakes sometimes hard abruptly due to misdetecting a vehicle ahead in a different lane as is it was in the car's same lane specially in curves or if the vehicle ahead but in a different lane is casting a shadow in front of car. Blind spot: blind spot detects a vehicle in the blind spot even when there's no vehicle. Noticed that car sometimes detects vehicles on an opposite direction road as if they're in the blind spot and it can set off the blind spot monitor.

VEHICLE SPEED CONTROL, FORWARD COLLISION AVOIDANCE: ADAPTIVE CRUISE CONTROL
When driving on a highway with cruise control on. If you are in an outside lane and the is a tractor-trailer in the inside lane maybe 100-200 feet ahead of you. If the highway veers to the left even though the truck remains in the inside lane the system seems to think the truck is right in front of the car. Cruise shuts down and it starts to brake. I have almost gotten hit by cars behind me twice. It has happened 4 times now. The first time was in mid June 2023 and three other times since. I asked about it and was told to go with manual cruise - I would have to manually do that each time I want to use it. Not acceptable and very unsafe. Reports of this type of incident have shown up several times on the Facebook Mazda CX-90 site. One other problem is with the front bushings. A hard right turn going over any kind of bump causes a severe rubbing sound.

VEHICLE SPEED CONTROL, FORWARD COLLISION AVOIDANCE: ADAPTIVE CRUISE CONTROL, FORWARD COLLISION AVOIDANCE: AUTOMATIC EMERGENCY BRAKING
When operating the radar cruise control, if a large truck (semi, box truck) is next to you when going around a curve, the vehicle is seeing that truck in your lane and applies the brakes very suddenly. This is an issue, because if someone is following behind you, it is almost as if you are brake checking them. Clearly that is not safe at highway speeds. This has happened to me several times since owning this vehicle.

VEHICLE SPEED CONTROL, FORWARD COLLISION AVOIDANCE: ADAPTIVE CRUISE CONTROL
Using the adaptive cruise control in I-64, the car will dangerously slow down/brake in the turns. If someone was following m, this slow down would have been unexpected, and could have rear ended us or lost control trying to avoid us. Unexpected slowdowns are dangerous. Not sure if this happens at lower speeds on side triads since I don’t use the cruise control on those roads.

VEHICLE SPEED CONTROL, FORWARD COLLISION AVOIDANCE: ADAPTIVE CRUISE CONTROL, FORWARD COLLISION AVOIDANCE: AUTOMATIC EMERGENCY BRAKING
While driving on freeway with Adaptive cruise control set, vehicle automatically brakes when passing large vehicles, like semi trucks. ACC set at 75, I'm in left lane to pass truck going around curve and brakes come on and slow vehicle down to 60. I am clearly in the left lane to pass and truck in right lane. My safety and those behind are at a HUGE risk. This will cause an accident if not addressed. I am going to get rearended, it's just a matter of time. I have taken it to dealership and have been told this is normal. No it is not! No warnings other than car slamming on breaks for no reason. This has happened several times. I put down the date it first happened. I am available to bring it to dearship, again.

FORWARD COLLISION AVOIDANCE: ADAPTIVE CRUISE CONTROL
My car detects a vehicle in front and slows down in the following scenario - when on cruise control and passing a big truck from the other lane and the road is bent toward the right or left. It's so annoying and I might get rear-ended one day as the vehicle behind me doesn't expect that I slow down. Very dangerous safety issue!

After turning vehicle off, two incorrect warnings appeared on the dash monitor. 1) “Rear Seat Alert. Check Rear Seats….” 2) Warning image and sound regarding the rear bumper. However, there were no objects in the back seats (except for a light sunhat that had been there for weeks), and there was nothing near the left rear bumper. In fact no objects for probably 10 feet from the bumper. I noticed this once, 10/24/2023 but it may have occurred before and I didn’t notice (I frequently get out of the car quickly when at my destination). Safety concern since the safety features are not giving correct warning signals.

Gear shift can easily slide from Drive to Neutral (and from Neutral to Reverse) if a book, purse, or other object is on the center console and slides forward and touches the gearshift when vehicle comes to a stop. Photos attached show me shifting from D to N with my pinky finger. This is a safety problem because if the center console is flat, making it easy for someone to place an object on it. When the car needs to stop somewhat quickly, the object on the console slides forward and pushes the gearshift into Neutral. This happened to me while I was in traffic, resulting in confusion as to why I could not drive the car forward after my stop. I then realized the car had been shifted into neutral. I shifted the car back into Drive and removed the object from the console. Safety issue for anyone beginning to drive this car wi the out this knowledge. Could also occur if a passenger (unknown to the driver) places an object on the console.

UNKNOWN OR OTHER
Safety issue, random, with 360 View Monitor cameras malfunctioning. This camera issue has happened randomly at least 7 times since I purchased the car in May 2023. The most recent occurrences were 10/26, 09/27, 09/23, 08/03/2023. What happens: when starting the car, 360 View Monitor should show images of surroundings. Instead, no image from the cameras shows; it’s black on the screen. Colored lines show the direction the car is backing up or moving forward, but the rest of the screen is black. When it occurs, it will remain in this faulty condition for the entire drive. The button on the console (left of gearshift) that turns on the image cameras when driving will show the same image. It will remain in this disabled mode until the car is turned off for a long time. I’ve tried turning it off and letting it sit until the computer sounds like it has shut off (2-3 min, perhaps), and restarting the vehicle — this does not cure the problem. The car seems to need to be turned off for a longer time. If I turn the car off and return in, say, 2 or more hours, the issue is cured (temporarily). Attached are still images from a video. This is random in occurrence and seems to be completely unpredictable when it will will happen. Safety issue.

UNKNOWN OR OTHER
Problem noticed shortly after purchasing the car in May 2023, and is a constant issue. Always: when driving, and when I press the the button to the left of the gearshift to activate the 360 View Monitor, the default image shows a useless, mostly black, image. (Scrolling to the other two, non-default images, they are useful images.). Instead, it gives the appearance of a black gap in the space around the car. I am attaching several still images from a video. Safety concern, because the image is not correct, and this is a listed safety feature.

FORWARD COLLISION AVOIDANCE: ADAPTIVE CRUISE CONTROL
When using adaptive cruise control and passing a large trailer or truck in the left lane (the trailer or truck is in the right lane), the adaptive cruise control system incorrectly detects the trailer or truck to be in the same lane as the CX-90 and in some situations can slam on the brakes causing a potentially dangerous situation.

FORWARD COLLISION AVOIDANCE: ADAPTIVE CRUISE CONTROL
The adaptive cruise control sometimes misreads the driving situation, especially on curves, and applies strong braking when there is no vehicle ahead in your lane. Especially when the vehicle in the adjacent lane is a truck. This could easily lead to being rear ended by a close following vehicle that is not expecting you to abruptly slow down. I had to turn it off on a trip on mountain interstates. I will address this at my first oil change at the dealer. I have had adaptive cruise on several other vehicles and never experienced this problem.

FORWARD COLLISION AVOIDANCE: ADAPTIVE CRUISE CONTROL
Hi, When passing a truck which is on the right lane of the car, the car recognise the truck as a car in it's current plane and putting a sudden brakes. I almost got rear ended couple of times in the last one month. Please request Mazda to fix this Adaptive Cruise Control issue. Thanks, [XXX] INFORMATION REDACTED PURSUANT TO THE FREEDOM OF INFORMATION ACT (FOIA), 5 U.S.C. 552(B)(6)

FORWARD COLLISION AVOIDANCE: ADAPTIVE CRUISE CONTROL
When ACC is on and speed is set, if the vehicle comes up onto a tractor trailer in the right lane, the CX-90 will think it is actually in front of my vehicle and abruptly slow my vehicle down, potentially causing myself to be rear ended.

FORWARD COLLISION AVOIDANCE: ADAPTIVE CRUISE CONTROL
The adaptive cruise control (ACC) system in the CX90 is experiencing a high number of false positive incidents, which could lead to accidents. The system consistently thinks that a vehicle in the right or left lane has moved in front of the CX90, mainly when going around a curve. This is especially common when passing 18-wheelers, where the system will start alerting the driver with a noise and flashing alert to depress the brake pedal. The system then begins emergency braking procedures, even though the 18-wheeler or other vehicle has not actually moved lanes. This rapid deceleration at highway speeds is incredibly dangerous, especially for vehicles and large trucks following behind the CX90. In all of my incidents, the system has detected a vehicle in the other lane, but the vehicle has made no deviation towards the CX90's lane.
