On 1/14/2026, I was pulling into a parking space in a parking garage when the vehicle abruptly accelerated causing the vehicle to hit the concrete wall in front of me. No braking assist or front collision warning issued. Airbags deployed. The car is currently at Joe Myers Collision Center in Houston, Texas to obtain an estimate for repair. The police did not respond to reported incident. Incident was reported to my insurance company immediately.

Following a professional brake flush at Roger Beasley Mazda Central in Austin, Texas, the left front brake bleeder screw was left loose. This resulted in a significant loss of brake fluid over several days, causing a 'Brake Warning' light to illuminate and a visible reduction in braking performance. A secondary inspection by an independent mechanic confirmed the screw was not tightened, which caused corrosive fluid to leak onto the wheel and compromised the safety of the vehicle.

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.

When driving, the car automatically apply the brakes even though there is no car or any obstruction in front of the vehicle. This happens 3-4 times in the last year. The i-ACTIVESENSE System malfunction. The brake system malfunction. Now I am receiving a Critical Vehicle Malfunction Alert. I am bringing my car to the dealer tomorrow morning (Monday, December 23rd, 2024) for it to be addressed. This is a very serious and dangerous issue and almost cost me an accident on two occasion.

I was hearing squealing, as if the brake pads were worn. Called the dealer to ask about parts, was asked to bring it in as it seems too soon for brakes. Upon inspection I was told my rear brakes are worn out at 22k highway miles, and will need rotors too. I asked how this is possible and for a manager whom then stated I could do just the pads. Still no explanation on how, but won't be covered on the warranty. I left without doing the repair because I wanted another mechanic to look at this since you can only get the rear pads from Mazda, so it's expensive. I do need this done and I believe there is a problem with the brake system or the electronic brake you hear engage Everytime you shut the car off. There are also several others complaining about this on Reddit, Google and YouTube, but Mazda seems to be looking the other way in it. I can say this is my 12th Mazda and I have never had one that has needed brakes before 60-70,000 miles and that was with city driving. There is clearly an issue and I'm not the only one.

The key light went on without me knowing what it was. Brakes are taking a while to engage. The acc stoped my car while driving in traffic almost caused an accident. Don’t know if this matters but phone charger does not stay connected with cover or not.

If any liquid or debris material enters the console cover area where many controls for the car are located, the “command switch” (as described by the Mazda dealer) underneath is destroyed. Many items are affected as noted above (some of which I could not check off). They have not responded as to whether some type of shield or even tape could be used to prevent this fault.

We were driving in a snowstorm during the daytime on a 2-lane highway with directional passing lanes (where it opens and closes, not crossing into oncoming lane to pass) from CO to UT. While passing a semi truck, with traffic in the oncoming lane, and behind us, the auto-braking activated. There were no vehicles in front of us. The alert went off, and the car rapidly slowed from 70 to 35, and applying the gas did not resolve the issue. This almost caused a rear end collision by other cars also trying to pass the semi. We think it was either caused by slush thrown up by the passed truck tires, or a slight curve in the road that made the computer think that someone was in front of us. Whatever it was, it was very dangerous to have the brakes slammed on on a snow road with vehicles all around us.

The manufacturer has deceived buyers concerning the towing capabilities: https://insidemazda.mazdausa.com/the-mazda-way/mazda-cx-50-offers-confident-towing-capabilities/ I bought the OEM tow hitch and wiring to achieve the advertised 3500 lb towing capacity, but according to the owners manual that is not possible as you are limited to 1000 lb without a brake controller which can not be purchased through Mazda. The trailer wiring and vehicle manual states that you must not modify it, which would be required to install a brake controller. I currently own a 2000lb trailer; I bought this vehicle specifically to pull it. There is no way to achieve this safely and legally despite the advertisements without aftermarket parts. If the required aftermarket brake controller install were to damage the vehicle's electrical system in some way, I doubt Mazda would cover that under warranty. The promotional material says nothing about non-OEM equipment first having to be installed in the car to achieve this tow limit safely. I'm sure the Mazda marketing department is well aware that this claim would make the CX-50 more appealing vs. it's competitors, however it is not accurate.

I was driving my vehicle and a large plastic part fell from the upper footwell and became lodged under the break pedal causing me to become unable to use the brakes. This is a major safety concern, and could have resulted in an accident.

At 10:16 am, I was driving home on Hall Rd. in Michigan. Hall Road is currently under construction and only two lanes are open and the speed is 40mph. It was raining pretty hard and also very windy. I was traveling West in the left lane and i noticed people in front of me began slowing down to about 10mph and going around an object I couldnt see. By the time it was my turn to pass said object, I realized it was a speed limit sign that had been knocked over by the wind. I went around it and pulled off to the side of the road where there was a small patch of flat, clear land (I believe there is a fire extinguisher or some kind of service system there). Try to act fast, I opened my door, removed my seatbelt and after looking for cars behind me, I ran across the road and picked up the large sign and moved it out of the way. By the time I had moved the sign, I noticed cars slowly approaching but were not willing to pass me. Then I heard them honking their horns but because it was raining hard, I couldnt see who or hear what they were saying. I figured Id look back at my car in case that was the reason and sure enough, it was and I jumped out of the way, and watched my car slowly fall off the ledge of the open roads and into the construction area of the new roads (there was a 2-3 foot deep and maybe 1-2 feet wide trench between the open road and the newly paved roads). My car then stopped abruptly, hanging over the ledge. Seeing the car had stopped completely, I opened the door and slowly got the car off the ledge. This did minor damage to the underside of my front and rear bumper but nothing serious. The problem I feel that is evident is that the car never engaged the electronic parking brake. This was a similar issue to what led to the death of [XXX] (granted, his shifting mechanism was an Audi style shifter and was shift-by-wire). I am not sure exactly what kind of automatic transmission is in my Mazda other than a 6spd. INFORMATION Redacted PURSUANT TO THE FREEDOM OF INFORMATION ACT (FOIA), 5 U.S.C. 552(B
