2025 Mazda CX-5 Problems

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)

On May 21st , 2026, while waiting in line to make a right turn (positioned 3rd in queue), the vehicles ahead moved forward. As I transitioned from the brake to the gas pedal to follow, the vehicle experienced an instantaneous engine stall and total electrical failure (NOT an i-Stop event). Pressing the gas caused the vehicle to slowly roll backward. When I immediately tried to reapply the brakes, the brake pedal became extremely stiff and nearly impossible to press down, failing to hold the vehicle effectively. The driver behind me began honking aggressively due to the imminent collision risk. I attempted to lower the windows to signal the other driver, but all electronic controls were completely dead. I had to quickly shift the gear into Park (P) and hit the start button to successfully restart the engine, which temporarily restored functions.

The vehicle exhibits unintended acceleration behavior when the brake pedal is applied. Instead of slowing down, the engine revs and the vehicle does not decelerate as expected. On March 16, 2026, while merging onto a highway and applying the brakes, the engine suddenly revved to approximately 3,500 RPMs while the vehicle failed to slow down. There have been previous issues with the vehicle not slowing when breaks are being applied, nut this is the first instance when it was noticed that the RPMs increased while breaking. This issue has also been reported to the dealership, with service documentation noting that when applying the brakes, the engine revs and the vehicle does not slow or accelerate properly. This creates a dangerous condition where braking input does not result in expected deceleration and may instead cause acceleration-related behavior. The issue has not been resolved. This issue significantly increases the risk of collision and loss of vehicle control.

While driving on February 12, 2026, the steering system failed, resulting in the steering wheel locking and becoming impossible to turn. While making a right-hand turn, the steering wheel suddenly locked. I had to forcefully jerk the wheel to regain control and avoid colliding with a concrete barrier on the right shoulder. After several seconds, the steering function returned to normal. This failure occurred without warning and created an immediate safety hazard due to loss of steering control. The vehicle has been inspected by a dealership, but the issue could not be replicated and no repairs were performed. This condition presents a serious safety risk as it can occur during normal driving maneuvers and may lead to loss of control and collision.

Description of Safety Defect: The driver-side exterior rearview mirror vibrates excessively, escalating into a violent shake depending on vehicle speed, crosswinds, and road surfaces. The issue is highly pronounced at highway speeds (65+ mph) and deteriorates aggressively as speed increases, particularly on open, wind-swept highways with like MA-3. ​The resulting violent vibration causes severe visual distortion, creating a blurred, "low-resolution" image that makes it incredibly difficult to accurately judge the distance, speed, and presence of overtaking vehicles. When checking the driver-side blind spot, this rapid blurring induces sudden, brief physical dizziness and vertigo, posing an immediate safety hazard during high-speed lane changes. The passenger-side mirror remains perfectly stable and clear under identical driving and road conditions. ​Attempts to Correct / Dealer History: The vehicle has been taken to an authorized dealership (Tulley Mazda, Nashua, NH) twice for this specific issue: ​On 03/18/2026 (Mileage: 5,862), Repair Order #XXX/1 noted the complaint. The technician verified the vibration on a road test but dismissed it as a "normal characteristic of the vehicle". ​On 04/21/2026 (Mileage: 6,846), Repair Order #XXX was opened because the condition worsened and began occurring at lower speeds. A ride-along was conducted, and the Shop Foreman confirmed the defect. Upon mirror disassembly, the technician found "loose internal components causing the issue". ​Current Status: Under warranty, the dealership replaced the body door mirror assembly (Part KJL1-69-181C) and the mirror glass/holder (Part TK71-69-1G7). However, the violent shaking remains completely unresolved and continues to worsen at high speeds. The dealership is now refusing further diagnostic or repair work, claiming the vehicle is "within spec," despite the persistent visual distortion and subsequent driver vertigo. No crash yet, but the defect is serious safety concern.

This vehicle was purchased two months ago. In that time the windshield has sustained multiple significant chips on multiple occasions during routine highway commuting. Some of these are in the line of sight of the driver, causing distractions or visibility issues. Prior to purchasing this vehicle I owned a 2012 Toyota Corolla, which traveled the same route every day and did not receive any significant windshield chips over a period of years. It seems that the windshield of the Mazda is particularly fragile and/or brittle compared to other windshields and suffers chips and cracks too easily.

The contact owns a 2025 . The contact was in a parking lot of a shopping center, put the car in gear and the steering wheel became inoperable , vehicle would not stop while depressing the brakes. Four additional vehicles were damaged from the impact with one vehicle deemed a total loss. The right front end was impacted including the hood and the right wheel. No additional property damage. The vehicle came to a stop in the parking lot from impacting the vehicles. Both front driver and passenger side air bags deployed. The vehicle was towed to a tow yard. The vehicle was deemed as a total loss by the insurance company. The contact sustained injuries left broken clavicle, left arm, left and right knees received lacerations and lacerations and 3 broken ribs on the left side and hematoma and received medical treatment at the emergency room intensive care. A woman in the back seat of one of the parked vehicles sustained minor injuries and received medical treatment. The dealer nor manufacturer was notified of the failure. The failure mileage was 2,837

Breaks and gas pedal simultaneously stopped working while driving and steering wheel locked up

At stop signs, in a row of 3 or 4 cars, on the 3rd or 4th stop, I apply the brake but it accelerates as i am braking, moving forward 8 or 10 feet. Over the course of 1800 miles, this has occurred 3 or 4 times, narrowly avoiding collisions.

Life-threatening, unoccupied rollaway vehicle with personal injury. Possible and/or suspected issues: "Not-P" switch circuit malfunction; "false park"; lack of cross-module redundancy; lack of BCM and PCM redundancy; Diagnostic Blind Spot; lack of Occupancy-Brake interlock; systematic safety failure culminating in unintended, driverless, runaway Zombie vehicle with personal injury. Background Info: * Low mileage, mainly in-town errands driving. * Not previously reported quirks, possible latent defects: liftgate opening that was hit-or-miss requiring multiple unlock trunk-unlock doors + get out of the car manual attempts; intermittent off-shutdown double-tap issue to power off car; ill-timed "rear seat alert". * Reported "engine won't start" resulting in three key FOB battery replacements and a locked key FOB. Day of Incident: * Auto-lock and the EBS were not used. * Driver intent was to park and unload, then permanently park. Car was in-park twice before ultimately placed in reverse and backed into position, facing downhill on a slight slope and along a left-side stone retaining wall. * Driver thought vehicle was fully in Park. * Attempted open liftgate via "open trunk, open door" routine, which did not work, so I exited the vehicle to try the manual liftgate button, which also did not work. * Three back-and-forth "unlock trunk/doors + manually press liftgate button" did not work. * Note: Upon opening the door or anytime after, I did NOT hear an audible warning that the car was not fully in Park. Nor did the car move/creep in any direction. * Deducing I must need to shut off the car to open the liftgate -- I leaned in and depressed the on/off button. * This caused the car to move forward, driverless, door open and scraping the stone wall, across a secondary road, over an 11" curb, and down a hill before stopping due to a tree. * I was injured. Pinned between a narrowing door and the car, I tried to turn the wheel right before being knocked down/falling

I pulled the car into garage, and realized it's not inside enough. So I moved the car forward, but forgot to place the shift to P position. With the shift in D position, I shut off the engine, opened the door, ready to get out. I did not notice the car was moving backward, until the open door hit the garage frame. I file a claim with my insurance, had the front door replaced in a local body shop. I confirmed that in D position, with engine shut off, the car can move freely in my drive way. I did have this issue in my other two cars, I occasionally forgot put the shift from D position to P position, but the car did not move. This issue - a car can move freely without driver's awareness - is a serious and dangerous issue. If this happens in the street, a serious crash can occur. The car manufacturer should figure a way to prevent this from happening when the shift is in D position and engine is shut off.

The driver side mirror vibrates at speeds above 65 miles per hour especially with windy conditions. Went to the dealer they replaced the mirror assembly with the issue still remaining. Mazda answer is that is common in CX 5 models. It is a safety issue as it really limits visibility for vehicles behind.
