See attached document for complaint.

Incident

May 20, 2026

On 06/18/2026, the vehicle displayed multiple safety warnings, including ABS malfunction, dynamic stability control/traction control malfunction, Smart Brake Support and Forward Obstruction Warning disabled, possible forward sensing camera malfunction, and airbag/seat belt pre-tensioner malfunction. These warnings involve braking, stability control, collision avoidance, airbag, and seat belt safety systems. This was not the first occurrence. On 04/24/2025, the vehicle displayed similar warnings, including critical brake system/Electronic Brake Force Distribution malfunction, ABS malfunction, Smart Brake Support and Forward Obstruction Warning disabled, possible forward sensing camera malfunction, and keyless entry malfunction. The vehicle was towed at that time. The vehicle was inspected by an authorized Mazda dealer in June 2026. The dealer replaced the battery under warranty, but I was not provided diagnostic trouble codes, a root-cause explanation, or written confirmation that the braking, ABS, airbag/seat belt, stability control, Smart Brake Support, Forward Obstruction Warning, and forward sensing/camera systems were fully diagnosed and verified safe. The dealer inspection report also listed the mileage as “No Mileage.” The vehicle is available for inspection upon request. I do not feel safe driving it because the repeated warnings involve braking, collision avoidance, stability control, airbags, and seat belt systems. I am concerned that an electrical, braking, or safety-control defect may disable safety systems while driving.

The contact leased a 2024 Mazda CX-5. The contact stated that the yellow electronic emergency brake light was displayed. The cruise control and rear brakes were inoperable. The brake pedal was pulsating while depressed. There was smoke coming from the front brakes. The vehicle was taken to a local dealer, who replaced the brakes, and the module was inoperable, but the failure recurred. The vehicle was taken to three independent mechanics, who determined that the rear brakes were firm. The manufacturer was contacted, and a case was opened. The failure mileage was approximately 24,000.

The contact owns a 2024 Mazda CX-5. The contact stated that while his wife was entering the garage, at an undisclosed speed, the vehicle suddenly accelerated; the brake pedal was applied but failed to respond, and it crashed into the refrigerator. The contact was concerned that the failure could have occurred while children were at play. No warning lights illuminated. There were no reported injuries, airbag deployments, fires, or police reports filed. There was a tire imprint on the garage floor. The contact called the local dealer, who scheduled an appointment. The vehicle was not diagnosed or repaired. The manufacturer was contacted, who opened a case and confirmed there was no recall coverage. The failure mileage was approximately 10,000.

Go down road, straight, less than 40, automatic braking system we off with no one in front of me or in lane next to me

Straight to the point, I backed the vehicle up, pushed the brake peddle in and shifted into park. The engine begun to increase in RPMs and I could hear the engine load increase, maybe about 2,000 to 5,000 rpms higher than idle or first start building vacuum idle, as if I was pushing on the accelerator. I literally looked down at the peddles, as I was just doing a quick spot change in my driveway, the accelerator did not appear to be stuck or in contact with the aftermarket winter weather plastic floor mat. I decompressed the brake peddle again and shifted the car from P to D and the engine went to its normal baseline idling RPMs and sound. I put it back in P and turned it off, no issue. I have noticed this problem before, but I only noticed it during this past winter season and blamed it on my winter boots and/or myself instead of the vehicle. I am going to guess this has happened in total about 4 times, including the most recent incident that I just wrote about. The CX-5 is connected to Mazda's network/ data service or whatever it is called, because I like my cars clock to maintain correct time, which it won't or can't do if I prefer my privacy from Mazda. So Mazda should be able to see what happened on their end. It happened in the late afternoon to early evening. I do also use 'auto hold' daily and cruise control w/out radar active.

The most recent incident: Driving 35 MPH on a 4 lane divided boulevard, vehicle 5-6 car lengths in front of me indicates intention to turn right. No traffic in lane to my left should I need to change lanes. I continue to coast. At approximately 2-3 car lengths, the vehicle in front has nearly completed the right turn - there is no risk of collision - but my car BRAKES HARD. This is the 4th time my car has activated emegency braking in a situation it is not warranted. I have been dirving for 36 years with no accident. I do not need nor want this technology as it is more prone to causing accidents than preventing them. Additionally, the car throttle response is slow to recover in these situations, so while I mashed the acclerator to the floor to avoid being rear-ended - the car did not accelerate for 1-2 seconds (RPM went up, but the engine did not engage for several seconds). In situations where AEB might have been marginally helpful, detecting cross traffic running red lights, the car has NEVER detected this - and thankfully I'm an experienced driver so AEB was not needed. This technology, IMO, is not safe and will lead to over-reliance causing more accidents in the future.

Incident

I had coplained about a long, soft brake pedal on 10 February 2024 to Hiley Fort Worth Motorcars and got a report on 13 February 2024 stated that after inspection, they could not duplicate my complaint, so they did a visual inspection and washed the car!!!! Today, 29 May 2024, I had to make an emergency stop and pressed the brake pedal to the floor! The ABS came on, but the brake pedal should never reach the floor. The other car had stopped and I swerved out of the way. No warning lights came on nor sounds. Additional information; if the brakes are applied by the adaptive cruise control, and you step on the brake pedal after the brakes have been applied automatically, the brake pedal is nice and firm, like it should be. But if there is no intervention with the car, the brake pedal is very long and soft.

I have a 2024 Mazda CX-5 but this is in any model and year that has the Adaptive Radar Cruise Control. When you set the distance you want to follow the vehicle in front of you, you will go the speed you are going until you come to the space you have set for the vehicle in front of you. Your vehicle will slow to match that vehicles speed. If that vehicle slows down, you will slow down. What it doesn't do it turn on your brake lights so the vehicle behind you knows that your vehicle is slowing down. Sometimes if the vehicle in front of you slows down fast, so does your vehicle. You have no control how fast it does that, it just does it. Now if the vehicle behind you doesn't realize that your vehicle has done this, well it has been very close two times so far. I do not want my new car rear ended. I did not know it did this with the brake lights and Mazda doesn't tell you that you have no brake lights when this happens. Why would they have a setup like this. It is like brake checking the vehicle behind you. I do not use my cruise control for that reason. It would be nice to be able to use it on a new car but I do not want to get hurt or get someone else hurt by doing so. I did contact Mazda and they know it does that. This is what they told me "Case Number [XXX]   Hello. My name is Dominique. I am sorry that you have had some very close calls while slowing down while vehicles were behind you. As for the question you had asked about cruise control activating the brakes when your vehicle starts to slow down, it does not activate the brake lights. It is just like when you are driving without cruise control and you go to take your foot off of the gas pedal instead of using the brake to slow down, it would not activate brake lights either unless you actually mash the brakes, the same with cruise control. Thank you for being a part of the Mazda family. " Isn't that great. I am now a safely hazard or at least my vehicle is, and they are all like that. Who knew. Not me. INFORMATION REDACTED PURSUANT TO THE FREEDOM OF INFOR
