My car caught on fire on [ccc] and it's completely burned down, a total loss. Following is information about my car and some summary of what happened. Car information: - Mazda cx5 2024 - bought in June or July 2024(car payment only made 22 times so far) - odometer 24,445mi(as of 05/15/2026) what happened: - in [xxx] Friday afternoon, I was in bellevue and noticed an engine overheat warning. So, I stopped immediately to cool down and called Mazda dealership(lee johnson Mazda) to schedule a service. - then after 20-30 minutes, I started the car again and the warning was gone. So I drove slowly and got on [xxx] to head home in kirkland. I was already driving slowly. - after a few minutes, overheat warning as well as engine warning started firing and noticed that smoke coming out of bonnet. - so, I pulled over on the shoulder near [xxx] and called roadside assistance. But even before I get connected to the roadside service, engine caught on fire and I had to call 911. - the car is completely burned down and it's a total loss. - state patrol wrote me a "exchange of information" and "tow/impound and inventory record". Why I am submitting this form: - this car is less than 2years old and has been seeing Mazda service regularly. The odometer checked by dealership on 05/15 is 24,445mi which is slightly more than 24,000 which is stated in the lemon law. But still, the car is pretty brand new and around 24,000 ish. So, I'm wondering if this still qualifies for lemon law. - even before this happened, I had a service history for engine warning and get the engine checked on 05/15/2026 which is exactly a week ago before the accident. Also, they said the engine thermostat had an issue and replaced and covered by Mazda's warranty. - overheat and engine warning was on and off. As soon as I pull over, it caught on fire. - this happened on [xxx]. It was very dangerous and lucky that we pulled over on right before it caught on fire information redacted pursuant to the freedom of information act (foia), 5 u. S. C. 552(b)(6).
While driving on the freeway, the car stopped having the ability to accelerate. The engine light came on, and I received a notification on the Mazda app stating there was an "engine malfunction. " I took it to Mazda, and they told me nothing was wrong. Flash forward a month and the same exact situation occurred. I took it to Mazda, and they told me the same thing. This is incredibly dangerous, as losing the ability to accelerate on a very busy freeway is life-threatening.
Incident description: on multiple occasions in January and February 2026, while operating a 2024 Mazda Cx-5 in reverse on low-friction surfaces (snow/ice) with a slight incline, the vehicle suffered a total systemic failure. System failures: while reversing at low speeds, the engine spontaneously shut off without warning. This resulted in an immediate loss of power braking and power steering. Simultaneously, the electronic gear selector (shifter) became non-functional, preventing the vehicle from being placed into 'park' to stop the uncontrolled rearward slide. Safety risk: the vehicle became a "runaway" object on several occasions. In one instance, the vehicle narrowly avoided crushing a pedestrian against another parked car, stopping only when the tires reached a different surface texture. In a separate incident, the vehicle slid uncontrolled down a residential hill, striking snowbanks. There is a grave concern regarding whether the supplemental restraint system (airbags) remains functional during these engine-stall events, as the dealer could not confirm occupant protection status during a total power loss. Inspection & reproduction: the vehicle was presented to an authorized Mazda dealer on March 3, 2026. The service department attempted to replicate the issue by reversing over soapy water on a gravel surface. However, due to the high friction of the gravel, they were unable to induce the specific tire-slip/low-traction conditions required to trigger the malfunction. No error codes were found during an informal scan, and no warning lamps or messages appeared prior to or during the failures. Component for inspection: the vehicle is available for inspection. I believe the failure is rooted in the traction control or engine management software, which appears to improperly shut down the powertrain when it detects specific wheel-spin patterns in reverse, subsequently disabling critical safety systems including brakes and transmission locks.

The contact owns a 2024 Mazda Cx-5. The contact stated while driving at 45 mph, the check engine light illmiunated. The contact mention when depressing accelerator pedal, the rpm's get suck independently and the vehicle fails to respond as intended. A dealer was contacted. The vehicle was taken to the dealer to be diagnosed, however the dignanoses was unknown. The vehicle was not repaired. The manufacturer was not notified on the failure. The approximate failure mileage was 39,381.
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.
This vehicle belongs to my friend, but I was the injured party. She was visiting me and realized she forgot her phone,. The vehicle wias at the top of my driveway and in park. She wanted to go back in the house to look and got out of the car & left the door open. , I leaned into the car to press stop engine and immediately the car began to roll down the hill, dragging me 50'. Car still in park slammed into the stone wall of my garage. I had injuries to my right leg. Aplit lip, frctured nasal bone, nerve damage to my thigh and torn meniscus. The ambulance arrived, I was taken to the hospital and treated. Witnesses signed affadavits confirming vehicle still in park. I have not been awarded any compensation since they say that my injuries were not serious enough. Mazda,at this time, has refused to take respomsibility since they could not duplicate the incident remotely tested by a calif. Facility. I am reporting this incident because all other parties have failed to do so.
