I have had my 2023 Mazda CX-50 for almost two years. Since I got the car, I have had no issues with the i-Activsense until June 2025. The reason I got the newer car was to ensure the safety of my family; however, Mazda failed to do their part. My car was recently involved in a car accident due to a faulty system. It appears that the newer Mazda CX-50s were included in a recall, but the 2023 model was not and it should be. On the day of the accident, my daughter was driving my car. The traffic was slowing down, and two lanes of traffic had to merge to one lane due to construction and all of a sudden, the car in front of her slammed on their breaks and the car could not stop in time before hitting them. My car never sent an alert until contact was made with the other car, and the emergency breaking did not activate. After my car hit the other car, an alert came on screen that indicated the i-Activsense was disabled. Once the car was turned off and then back on the alert disappeared. Additionally, I am now having issues with the rear camera not alerting if someone is behind me (car or pedestrian). I have a 2019 Jeep Grand Cherokee that will slam on the break for you if you get too close to an object when you are in reverse. Isn't that what the Mazda CX-50 should be doing?

On [XXX], our 2023 Mazda CX-50 experienced a failure of the control arm, which was confirmed by Auffenberg Mazda of O’Fallon, IL, to be a manufacturer’s defect. Despite this, the dealer informed us that the vehicle was safe to drive. However, Mazda corporate contradicted this, stating the vehicle is unsafe to drive and instructed us not to operate it. We were informed that the replacement part will not be available until sometime in July 2025, leaving us without a safe vehicle for nearly two months. Both Mazda corporate and Auffenberg Mazda of O’Fallon, IL, have refused to provide a loaner vehicle or commit to reimbursing rental car expenses during this period. Additionally, Mazda corporate has failed to maintain consistent communication, not returning calls when promised and leaving us without timely updates or resolution. This situation poses a significant safety concern and financial burden, as we are left without a reliable means of transportation due to a confirmed manufacturing defect. We request that the NHTSA investigate this issue, including the conflicting safety assessments provided by the dealer and Mazda corporate, the delay in part availability, and the refusal to provide a loaner vehicle or rental car reimbursement. We also urge an evaluation of the control arm defect to ensure other Mazda CX-50 owners are not at risk. INFORMATION REDACTED PURSUANT TO THE FREEDOM OF INFORMATION ACT (FOIA), 5 U.S.C. 552(B)(6)

The stock manufacturer brakes on this vehicle have been known for issues. There is a open recall on some models but according to records my vehicle does not fall under the listed VIN numbers associated with the recall. Although my vehicle experiences the same concerns the recall list stats. The brakes seem to intermittently have trouble slowing the car down while ascending slopes and coming to a immediate stop. Often you are forced to use excessive force on the pedal and it still does not come to a complete stop.With the amount of forced iv had to use in the past the brakes should lock up and and create a slide but iv never experienced it. If im am not careful and maintain all attention to what its front of me i fear i will create a accident some day. To often in stop and go traffic or abrupt braking situations i have not been able to assure the vehical will stop . This causes concerns due to always having to travel at slower speeds and politically car repair bills. The life expectancy on the brakes are wearing out quickly. I am not a aggressive driver so i should have no problems with premature brake wear. Iv had the brakes inspected by the same dealership multiple times but they always say there's nothing wrong. The brakes have felt the same since purchasing date. Now we are two years into own the vehicle. The dealership is no help and the manufacture is not as well.

On the freeway going 60 MPH, the safety system malfunctioned and applied maximum braking - as if I was going to collide with something in front of me. It was frightening. There was a 1/4 mile of open road in front. It happened 2 more times in the next 2 miles on the interstate. Background: I had been driving through a snow storm for a couple hours prior to the incident and I received a forward camera dirty warning. I was in the left lane (of 3 lanes) with a concrete barrier about 15 ft to my left. All 3 times, there was a semi truck & trailer on the right. I was in no danger of collision. I took the CX50 to the Mazda Dealer and the issue was escalated to the regional service techs who said the auto was "working as intended" I vehemently disagree. I am lucky there was no one driving close behind me, otherwise there would have been a terrible accident
