ELECTRICAL SYSTEM, VISIBILITY/WIPER, BACK OVER PREVENTION: WARNINGS
The vehicle's Connectivity Master Unit (CMU) / infotainment system has experienced a complete, permanent internal electronic failure, logged by Diagnostic Trouble Code DTC U3000:49 (Control Module Internal Electronic Failure). The main display screen is completely dark at all times and never powers on or responds. The unit is available for inspection upon request. This total hardware failure creates critical safety hazards: 1. Non-Compliance with FMVSS No. 111 (Rear Visibility): Because the rearview camera relies entirely on the main display screen, the backup camera is 100% inoperative. When shifting into Reverse, the screen remains black, offering zero rearward visibility and creating an immediate backover risk to pedestrians, children, and property. 2. Complete Loss of Driver Assistance & Emergency Systems: The permanently dark display eliminates access to active safety guidance, rear cross-traffic visual alerts, parking distance indicators, turn-by-turn navigation, and hands-free emergency communication interfaces. 3. Ongoing Driver Distraction: Operating the vehicle without essential safety/navigation displays requires additional driver focus, causing persistent cognitive distraction. The failure was confirmed via professional OBD-II diagnostic scanning showing DTC U3000:49, which explicitly denotes an unprovoked internal component failure rather than wear and tear. The manufacturer has declined to repair or replace the failed assembly out of warranty.

ELECTRICAL SYSTEM, UNKNOWN OR OTHER
I was denied work on a network issue recall 3 separate times at the dealership I bought the car. The first time I was told it was because of a smell. If I clean the car, they will fix it. I noticed after they were in the car my backup camera didn’t work which I also thought might be a recall but found out it wasnt. I went ahead and cleaned it twice. I came back they alleged it smelled like cat litter and urine. I asked to speak to someone else because there was nothing in my car and I know it didn’t. There were also no stains, mold, anything like that. It smelled of cleaning products. But I took it home and scrubbed extensively even though I was confused by the comment. When I went there it was smelling like lemon. Zero stains, mold, nothing in the car but maybe a little sand and baking soda. The person went as far as to say wow the car is improved said but thry still sorta smell it and there’s stuff on the window (there wasn’t). At that point I knew I was being picked on because either they didn’t know how to fix it or didn’t want to work with me. It felt discriminatory and differential to others. I now have a super clean car but a network issue and no backup camera because of this. They claim now they fixed everything but a non-safety issue but I also still have two errors that say “telematics” and “networking issue have vehicle inspected.” I believe I have rights under NC lemon law as this is within 24 months of purchase with only 4600 miles

While driving on the highway (50mph), the sunroof had shattered unexpectedly. The sunroof itself was not open, but the visor was open so the glass fell into the car, onto the driver, the passenger and into the backseats. The glass shattering sounded like a gunshot which startled us while on the highway, and the broken glass cut the driver.

The vehicle was involved in a rear and side impact collision and the car was totaled on 5/14/2026. The air bags did not deploy. There was a recall on the air bag system immediately after purchase 6/28/2025 and it was taken in July of 2025 to Mazda of Columbia, SC and it was “repaired.” The airbags of the truck that collided with the Mazda did deploy.

SEAT BELTS
I am reporting a catastrophic failure of the rear seatbelt restraint system in my 2025 Mazda 3. The rear seatbelt guide geometry is badly designed, allowing the webbing to bunch and jam during normal operation. This physical obstruction prevents the seatbelt from retracting, leading to three severe safety hazards: 1) Total failure to restrain occupants. 2) Structural damage to the vehicle's safety cell. 3) Public hazard where the obstructed door rebounded open into oncoming traffic. Restraint Failure: On multiple occasions, the rear seatbelt jammed in the guide clip while in use. Due to the lack of retraction, a 200lb adult passenger was able to fully exit the vehicle while the belt remained buckled. Most alarmingly, the vehicle's safety logic failed to trigger any occupancy warning alarms. The system remained "satisfied" because the buckle was engaged, despite providing zero tension or restraint to the occupant. Structural Damage & Public Hazard: Because the belt failed to retract, it remained loose and obstructed the rear door's closing path. The door rebounded off the slack belt into oncoming traffic, resulting in a significant structural dent to the C-pillar (door jamb) immediately adjacent to the striker. This deformation occurred in a critical area for side-impact protection. Efforts to Resolve: The vehicle was inspected by a dealer, who claimed the system was functioning normally despite being shown the jamming. I escalated this to the Mazda North American Operations Executive Office. The executive team issued a final dismissal, refusing to provide technical answers or acknowledge the documented failure points. Crucially, they denied my request for a Regional Technical Manager (RTM) to perform an engineering review of the guide geometry and refused to inspect the damage to the C-pillar. By refusing a corporate inspection, Mazda has ignored a reported life-safety defect and its resulting structural damage. This is documented on a video provided

POWER TRAIN, FORWARD COLLISION AVOIDANCE: AUTOMATIC EMERGENCY BRAKING, FORWARD COLLISION AVOIDANCE: ADAPTIVE CRUISE CONTROL
left-most lane of a three-lane highway, I pressed the accelerator to maintain the flow of traffic. The vehicle suddenly began revving between 4,000–5,000 RPM without increasing speed. When I attempted to accelerate again, the RPM remained around 3,000, and I immediately received multiple warning messages on the dashboard, including: “Skyactiv Partially Disabled” warning Engine Malfunction warning ATF (Automatic Transmission Fluid) warning light Simultaneously, the vehicle rapidly decelerated from 65 MPH to approximately 55 MPH, creating an extremely hazardous situation and nearly resulting in a collision. I had to carefully maneuver across lanes to reach the shoulder. After shutting the vehicle off and restarting it, the warning lights temporarily cleared; however, the vehicle appeared to be operating in limp mode. I had the car towed home via AAA. After this near-fatal incident, I scanned the vehicle using an OBD2 reader and retrieved diagnostic trouble codes P0780 and P0761, indicating Shift Malfunction and Shift Solenoid 3 Performance issues. To address the issue proactively, I had my mechanic perform two full transmission fluid and filter exchanges on Monday, February 16, 2026, and again on February 18, 2026. Both services included a pan drop, replacement of the transmission filter, use of Mazda OEM transmission fluid (0000A7115QT and FZ01-21-500), and a complete transmission relearn procedure after each service. Despite these efforts, the same codes (P0761 and P0780) reappeared when scanned with a professional-grade diagnostic tool. The battery has been tested and confirmed fully charged. Additionally, my mechanic identified oil leaking from the timing chain cover.

POWER TRAIN
My rear differential case cracked, anytime the four wheel drive system was engaged the entire drivetrain would lock up. Luckily we were only on side roads so going less than 30 mph if we had been on the highway when this happened we could have been in an accident or lost control. The dealer did confirm the problem and it was fixed under an extended warranty. There was no warning just all of a sudden a loud bang and all the wheels locked up. I have a copy of the video inspection done at the dealer if there's anyway to send that. I can get a copy of the repair invoice if needed

ELECTRICAL SYSTEM, STEERING, SERVICE BRAKES
On 14th, 2026, while traveling at approximately 60 mph on the northbound 55 Freeway near the Katella exit, my vehicle suddenly began to shake violently without any prior warning. In response, I attempted to slow down by applying the brakes; however, the speedometer rapidly increased even as I maintained firm pressure on the brake pedal. Immediately afterward, the vehicle pulled sharply to the left, causing a complete loss of steering control and resulting in a collision with the center median barrier. Despite the force of the impact, the airbags did not deploy, raising additional concerns about potential safety system failures. At no point before the incident were there warning lights, alerts, or indications of mechanical or electronic issues. The vehicle had also undergone its regularly scheduled maintenance at the Tustin Mazda dealership on January 2nd, 2026, just prior to the accident. Given the sudden shaking, unintended acceleration, loss of braking effectiveness, steering failure, and non‑deployment of airbags, I believe this incident may involve one or more manufacturer defects affecting critical safety systems. I respectfully request that NHTSA investigate this matter. I also believe the vehicle’s Event Data Recorder (EDR) may contain information relevant to identifying the root cause of these failures.

VEHICLE SPEED CONTROL
Transmission control unit (TCU) failure with error code P061B in 2022 Mazda 3. Problem began approximately 6 months after purchase (February 2023, mileage 8181). Despite five repair attempts by Russell & Smith Mazda Houston (August 8, 2023; January 22, 2025; April 8, 2025; October 13, 2025; December 23, 2025), dealer has been unable to correct the issue. TCU malfunction substantially impairs vehicle use and creates serious safety hazard.

ELECTRICAL SYSTEM
“My 2022 Mazda 3 is experiencing an ‘in-network malfunction’ related to the vehicle’s internal communication system. Multiple technicians have told me this is an internal vehicle network/communication fault, not caused by wear or damage. The dealer refuses to repair it unless I pay out-of-pocket, even though this appears to be a manufacturer defect in the electrical network system, (TCU)This malfunction affects the reliability of the vehicle’s electronics and could impact safety systems while driving. Mazda has not taken responsibility for diagnosing or repairing the issue, and I believe this defect needs to be investigated, as other owners may be affected as well.”

ELECTRICAL SYSTEM
Car doesn't start if sitting more than 4 days untouched. When i went to the dealer, they informed me they know about the issue but nothing can be done about it. They even told me what the issue was, there's something in the car (they don't know what) that draws a lot of power non stop. kills the battery and some time will get stuck mid ignition. I've replaced the battery a few times as well. It's very stressful trying to deal with it after a 12-16 hour shift at work. knowing it will happened again and again, over and over.

SUSPENSION, WHEELS
January 10, 2025, at low city speed, I struck a small pothole. The entire car felt like it had been in an accident—a violent jolt—followed by immediate vibration and a pull. Inspection showed one OEM 18" rim was bent. I contacted Mazda after diagnosing and was offered a slight discount on the replacement rim, not a warranty repair or full diagnosis. I have the bent rim in my possession. July 2025, at low speed, I barely contacted another small pothole and immediately felt the same drivability issues. A second rim was found damaged. This was only 4,500 miles after the first incident. I called the dealership manager; he said he would get back to me but never did. I later sent a letter that went unanswered. My subsequent research shows innumerable similar owner complaints for 2020–2025 Mazda 3s experiencing rim deformation from ordinary road irregularities. Why this is a safety issue (technical points): Bead-seat deformation & air loss: A bent alloy rim can distort the bead seat, causing slow leaks or sudden deflation, especially after heat cycles—creating a loss-of-control risk. Dynamic instability: A rim that’s even slightly out-of-round produces high-frequency vibration, steering pull, and reduced traction in turns or under braking; it can trigger ABS/ESC interventions and increase stopping distance. Load path & suspension stress: The 18" low-profile package leaves little sidewall cushion. On normal bumps/potholes, impact energy transfers directly to the wheel. Repeated “bottom-out” events may damage shocks/struts, alignment, and tires, compounding instability. Repeatability & foreseeability: Two events under ordinary use within a short interval indicate a systemic integrity problem, not random abuse. Requested resolution: A no-cost remedy: (1) replace all rims/tires with more durable parts and inspect/repair suspension; or (2) provide comprehensive wheel/tire protection and repair damaged rim; or (3) exchange he vehicle for a comparable model with no issue

SERVICE BRAKES, ELECTRICAL SYSTEM, FORWARD COLLISION AVOIDANCE: AUTOMATIC EMERGENCY BRAKING
Car gives me emergency brake warnings about imminent collision maybe once or twice a week with nothing in front of me what so ever and once even straight up just brought me to a complete halt in the middle of the road with absolutely nothing in the road. The dealership basically told me it was a known issue and that “some models are more sensitive than others” and that they will be doing nothing about it. Different models of Mazda 3s from the same year are currently being investigated for the same recalls. This definitely needs to be addressed before I get into an accident.

AIR BAGS
I recently received a warning on the dashboard that there is an airbag malfunction and needs to be taken in to get serviced. The warning continues to appear. This appears similar to a recent recall of 2024-2025 Mazda 3s and CX-30s, but there does not appear to be a recall issued for 2022 Mazda 3 models. I have scheduled an appointment for July 24, 2025 at the Mazda dealership to get my vehicle inspected, but because there is no active recall, Mazda states that I may have to pay for the diagnosis and any repairs. I disagree that I am required to pay for any diagnosis/inspections/repairs.

STRUCTURE:BODY, AIR BAGS, LANE DEPARTURE: BLIND SPOT DETECTION
On July 1, 2025, I was involved in a severe rear-end collision while driving my 2024 Mazda3 manual hatchback. The impact was forceful enough to shatter the rear windshield, leave a deep dent in the tailgate, and bend the trailer hitch mount under the vehicle by several inches. Despite this, none of the airbags deployed, and there were no airbag warning lights before or after the crash. After the incident, I checked my vehicle’s VIN on NHTSA’s recall lookup tool and discovered that Recall 7525E had been issued on June 6, 2025, for a critical airbag sensing system defect (SAS module), which can disable airbag deployment after battery depletion or improper power conditions. According to Mazda and NHTSA documents, this defect can completely disable airbag function, increasing the risk of injury in a crash. As of July 11, 2025, I have not received any recall notice from Mazda by mail, email, phone, or dealer contact—despite being the registered owner. Mazda’s documentation shows that: Dealers were notified as early as June 3, 2025 Owner letters are not scheduled until July 28, 2025 This means that I was driving a defective vehicle without knowledge of a serious safety issue at the time of the crash. I believe that: Mazda failed in its legal obligation to notify me in a timely and adequate manner. The non-deployment of airbags in my crash is consistent with the failure described in Recall 7525E. Other affected Mazda owners may remain unaware and at significant risk. I respectfully request that NHTSA: Investigate whether Recall 7525E was the cause of airbag failure in this incident. Determine whether Mazda’s recall notification practices met regulatory requirements. Ensure immediate outreach to affected owners to prevent further injury or risk. I am also seeking legal counsel due to the serious safety implications and potential liability arising from this defect. I will be retaining all documentation, vehicle records, photos, and post-

I found out about this recall today. Mazda doesn’t have a fix to this recall yet. I am scared to drive my car in the event of a crash, due to the fact that my airbags won’t go off due to the recall. Mazda said to just “be aware until we have a fix” I cannot just “be aware” if I get into an accident and my airbags don’t go off.
