The vehicle exhibits a repeatable low-speed driveline-related problem consisting of pronounced clicking or clunking from the driver-front area, fore-and-aft jerking, and harsh engagement during deceleration and light on/off-throttle transitions, particularly around 15–17 mph; the behavior can become significantly worse over rough or uneven terrain. The exact failed component or system has not yet been identified. The vehicle is still essentially new, with fewer than 5,000 miles, and has not yet reached its first scheduled service interval, so it has not yet been formally inspected for this condition. No warning lamp or diagnostic message has appeared. Other owners online have described a similar low-speed clunking and jerking phenomenon, and Mazda has issued at least one prior transmission-related TSB addressing somewhat similar harsh shift behavior, although that bulletin does not appear to apply to this vehicle or this exact symptom. The vehicle is available for inspection upon request. The concern presents a potential safety risk because the vehicle can unexpectedly jerk, lurch, or abruptly change driveline load during ordinary low-speed driving, which can make accelerator response and vehicle speed less predictable in traffic, parking lots, intersections, or on uneven surfaces. The symptoms began within the first few thousand miles and remain repeatable.

The vehicle was brought to Mazda three times for the same brake-related concern. The issue occurred during braking and has not been resolved despite inspections and repair attempts.” If you’re listing each visit, do it like “Visit 1: Customer reported brake noise. Dealer inspected. Visit 2: Same concern returned, vehicle brought back for diagnosis and repair. Visit 3: Brake-related issue reported again. Problem continued.” That keeps it clean and close to the service records. And it at a dealer ship for the 4 time already , and they keep saying it the brakes but now I have to pay for the fix when I was complaining about well under wa

At about 6:50am July 7th 2026, I was getting in the exit lane of interstate 50 to exit. I merge into the lane and being applying my breaks since I was going about 55-60mph. However, my vehicle did not slow down. I began to press harder, it still did not slow down, so I pressed as hard as I could because I was rapidly approaching stopped vehicles. The vehicle began to make a grinding sound, it started shaking, and then a "break" light appeared on the instrument panel. After this it came to a sudden and violent stop. I have taken it to the dealership for similar issues many times since I got the vehicle in October 2025. Each time they state that they cannot replicate the issue and the vehicle operates as it should. It is under warranty so I have not taken anywhere other than the Mazda dealership.
I have a serious safety issue with my 2025 Mazda CX-5, purchased new in January 2026 from Island Mazda on [XXX]. A few days before the critical alert, I noticed the car stopping on its own before pressing the brake. While driving on the highway, I received a “faulty sensor” alert that went away. On July 10, 2026, I received a Critical Vehicle Malfunction Alert in the MyMazda app. The app gave no specific details. I called Mazda Customer Experience. They confirmed via email the system labels it as a Parking Brake Malfunction and instructed me not to drive the vehicle. They advised it could stop at any time or not stop. I also experienced pulling and unprompted braking while driving. On XXX, I called Island Mazda service multiple times (calls went to a call center). No callbacks. I went in person. General Manager [XXX] was unavailable; Sales Manager [XXX] advised towing to [XXX]. The car was towed XXX at 1:29 PM. No confirmation call. I called again at ~2 PM. Technician [XXX] called first. Service Manager [XXX] later called and was rude/dismissive. He yelled when I mentioned lemon law saying he can no longer speak to me when i mention that, downplayed the issue, refused to discuss documentation, and suggested I test drive the unsafe vehicle with them to figure out whats wrong. He spoke over me and said it would take a long time to fix because they are busy. He said he would forward my case to someone else and i agreed he is not capable of handling this appropriately. This is a brand new vehicle under warranty. I have a [XXX] son with congenital adrenal hyperplasia (rare condition requiring stress-dosing for injury). I do not feel safe driving it since the alert never even appeared in my actual car just the mazda app on my phone i do not trust the dealership after this treatment to fix it. Requesting full investigation into the defect and dealership handling. INFORMATION REDACTED PURSUANT TO THE FREEDOM OF INFORMATION ACT (FOIA), 5 U.S.C. 552(B)(6)

The automatic emergency braking system prematurely and overly-aggressively takes over when I have full control of the situation. When it takes control it locks up all four wheels, each time almost causing a rear-end collision. It has done this on a total of 4 occasions under normal congested traffic situations. On or about 6/14/26 I was driving westbound on the Massachusetts Turnpike. There was a sudden traffic stop. I had sufficient distance to stop before colliding with the car in front of me and further had the passing side breakdown lane to divert into if necessary. The emergency braking software took over and locked up the wheels causing the person behind me to have a rear-end collision with my car. There was little-to-no damage and no injuries. The dangerous turnpike traffic conditions discouraged making a police report. Conclusion: System is overly aggressive and creates undue risk of personal injury. The risk far outweighs any benefit the system offers. - Plans to report issue to Mazda during next maintenance appt -No warning lights -Problem is re-occurring but not with independent entity (yet)
