2024 MAZDA CX-90 Complaints

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.

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.

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.

This vehicle at highway speeds will suddenly brake when intuitive cruise control is engaged. It mainly does this when the hwy is not straight and there is a vehicle ahead in a different lane or if there is a concrete median on either side. It’s not safe to be going 70-78mph and have your vehicle brake and bring speed down to 50-60. I’ve had intuitive cruise control on 3 other vehicles and none of them did this. Vehicles following become upset when vehicle brakes with no vehicle ahead of us. Also, it’s a danger of being rear ended or causing a road range incident when someone behind you thinks you are brake checking them.

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!

Driver side mirror shakes at speeds over 45 mph which makes viability in driver side mirror unsafe and distracting while driving.

The vehicle incorrectly sensed a large truck in the right lane, next to the lane I was in, as being in my lane causing the vehicle to slam on the brakes and caused me to nearly get rear ended by following vehicle. Other vehicle had no notice, as my lane was completely clear. Further testing on my part found that numerous vehicles had incorrect lane placement on the provided graphical display. Dealer says everything checks out normal. This is a major safety issue for me.

While traveling in the left lane on a 2 lane interstate, 79S, the car suddenly braked as I passed a truck in the right lane entering a curve. The "apply brake now" emergency message also flashed on the display. Had a vehicle been closely following behind, it would have crashed into my rear

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.
