Mazda CX-5 2025

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.

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

I was driving from Rock Hill, SC on October 17, 2025 on Route 77 South when I heard an explosion while talking to my daughter at approximately 8:40 am. I stopped the car twice to check the tires. On the second stop, I lifted the hatch but did not see anything. I got back into the car and decided to open the sunroof slide just a bit. I opened it slowly and saw shards of glass and put my hand up through the hole. I closed the slider carefully. I continued to drive to the Florida Welcome Center where I found a maintenance man to put duck tape over it. This did not hold. I was only driving about 60 mph as I was afraid that glass would fly out and harm the vehicle behind me. I decided to stop at my son’s as it was closer than my home. The next morning we purchased vinyl and duck tape to cover the hole better. I called my Mazda dealership while in SC. They said to bring it in for them to look at it on Monday. I called again at the Welcome Center to see if I should cover it. They said that was best. It is now Monday morning, October 20, 2025 and am at the dealership. Mileage is approximate.

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 system that failed was the acceleration. This how it happened the first time, because after that it has happened at least two more in one year. I was leaving my office parking area, and I was waiting for the cars in front of me to continue moving. Then I was ready to start moving and put my foot on the accelerator and just went to a high acceleration. Which I immediately slammed the brakes because otherwise I would have smashed the rear part of the vehicle in front of me. My safety was in jeopardy because if I would have hit the car in front of me and my airbags would have deployed. And the speed of the acceleration was so, that the driver in front of me would have definitely felt it in his neck and God forbids what else!!! Yes, I reported to my dealer, and they said that nothing showed in their computer system, and mentioned something of a throttler not been wrong, (which I don't know what that is). There were no warning lamps or messages in the dashboard prior to the failure. This happened to me again in random occasions where I was just getting my car out of my parking in my condominium, also lucky, it was early in the morning and no cars around. AND the other instance also in my condominium parking area, but this time arriving, and also, lucky no cars near!!!! Your website describes a similar complaint for the same make and model of my car, thus implying that there is a problem with the system.

My 2025 Mazda CX-5 includes a Traffic Jam Assist (TJA) stop and go feature. This feature allows the adaptive cruise control to move the vehicle in traffic with minimal drier intervention. As traffic advances the vehicle moves. If traffic stops, the vehicle stops. When clear of vehicles based on the set safe space setting in the adaptive cruise control, it resumes the predetermined speed set in the adaptive cruise control. The problem: While in "traffic jam assist" (TJA) mode, if changing lanes L or R to a lane that has vehicles farther away (clear lane), the cruise control radar/camera then sees a clear opening and begins accelerating to the predetermined speed on the cruise control. However - at this time the system fails to recognize a that another vehicle is farther ahead. maybe 4 or 5 car lengths ahead, and continues accelerating dangerously close to the next vehicle (I cannot say if it will stop or not because I have intervened to apply the brakes), cannot risk a rear end to another vehicle.The system fails to recognize that another vehicle is present after a lane change has occurred and braking or slowing as expected does not take place. This is a common repeatable scenario. The failure to recognize another vehicle after changing lanes is a serious and dangerous problem that should not be taking place. This poses an accident risk from an automated system that has a inherent flaw in its logic/design. The NHTSA should investigate this system and determine what corrective action can be taken to prevent a collision while using this system.

While driving at various speeds, including highway speeds, the vehicle intermittently fails to slow down when the brake pedal is applied. On multiple occasions, the brake pedal was pressed but the vehicle did not respond appropriately and continued moving forward. On December 1, 2025, while traveling at approximately 65 mph on the interstate in rainy conditions, the vehicle began making a grinding sound and started sliding instead of slowing down. The vehicle briefly lost the ability to decelerate, creating a near-collision with a semi-truck. On December 22, 2025, the issue occurred twice in one day. While attempting to brake at a stop sign and in traffic, the vehicle did not slow down, nearly causing collisions with vehicles in front and adjacent lanes. In the instance where approaching the stop sign where a vehicle was stopped, the dashboard flashed “break” while I was breaking as hard as I could. Warning lights and sensor-related alerts have appeared intermittently prior to and during some incidents. The issue has continued intermittently, including additional incidents where the brakes were either unresponsive or overly sensitive. They do not respond in a consistent or predictable manner, making safe driving nearly impossible. This problem places myself and others at significant risk of collision due to loss of braking control. The vehicle has been taken to multiple dealerships for inspection. The problem has not been successfully replicated, and no repairs have been performed to resolve the issue. Dealership documentation includes customer reports of “NOT BRAKING” and brake malfunction concerns.

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)

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.

1.What component or system failed or malfunctioned, and is it available for inspection upon request? The vehicle exhibits trembling while idling and previously showed erratic behavior during hard stops. Possible issue with the engine control software or powertrain system. The vehicle is available for inspection upon request. 2.How was your safety or the safety of others put at risk? The trembling at idle and inconsistent braking behavior compromise vehicle stability and driver control, especially in heavy traffic or emergency situations. These symptoms raise serious concerns about a potential underlying defect. Mazda has issued recent software-related recalls involving loss of drive power—though not for my model—which heightens my fear that similar risks may exist. I should not have to wait for a catastrophic failure or breakdown to validate my safety concerns. By then, it may be too late. I do not feel safe driving the vehicle. 3.Has the problem been reproduced or confirmed by a dealer or independent service center? Yes. Mastria Mazda in Raynham, MA acknowledged the issue and performed a software update. While braking behavior improved slightly, the trembling at idle and other concerns persist. 4.Has the vehicle or component been inspected by the manufacturer, police, insurance representatives or others? No formal inspection has been conducted. I mailed a detailed letter to Mazda’s corporate office in Hiroshima in July 2025 and received confirmation of receipt, but no response or inspection followed. I also mailed a letter to Quirk Mazda, the dealership where I purchased the vehicle, and received no reply. When I attempted to discuss the issue the service manager at Quirk Mazda dismissed my concerns and stated it would be “impossible to recreate” the issue. No one from Mazda or its representatives has contacted me to inspect or address the problem. 5. No warning lamps or dashboard messages appeared. The trembling and braking issues began shortly after purchase.

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

2025 Mazda CX-5. The vehicle experienced a severe, dynamic charging system failure that creates an active safety hazard on public roads. A dealership service department attempted a software update, which turned off the active dashboard layout indicator but completely failed to resolve the root hardware issue. The system failure remains active and has thrown consecutive advanced safety system faults. VEHICLE DIAGNOSTIC TIMELINE & BRIEF •Vehicle: 2025 Mazda CX-5 •Warranty Status: Active (Under Bumper-to-Bumper New-Vehicle Limited Warranty) •Modifications: None (100% Factory Standard; No aftermarket accessories) On the evening of [XXX], while preparing to leave on a cross-country trip, the car would not start. It was originally believed it was because while loading the car we left one of the key fobs in the car and tried to lock the doors. We reset the fob and tried the manual override to get the car to start with no luck. There were several warning lights coming up on dash to include an istop warning. Unfortunately, I didn't take pictures of the original incident. We contacted AAA and they came and jump started the car. We left on our trip the morning of [XXX]. The car started with no issue. That afternoon as we were driving through a small town, we stopped at a traffic light and received the "Battery Malfunction" warring light. We headed to Auto Zone, they checked the battery and said it had low charge, even though we had just driven the car over 400 miles. We parked the car at the hotel fulling expect to have to call AAA again but the next morning the car started without a problem. On [XXX], we continued our trip. When we stopped for gas that afternoon the car would not start. We again had to jump it. When we left the gas station the check engine light came on (amber). We were close to Wichita Falls, TX so we stopped for the day and made an appointment with the dealership there for the nINFORMATION REDACTED PURSUANT TO THE FREEDOM OF INFORMATION ACT (FOIA), 5 U.S.C.
