2023 MAZDA MAZDA3 Electrical System Problems

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...

I was driving on the highway and decided to switch int the left lane so I sped up and heard a big bang and what sounded like my bumper being dragged against the ground. I see on my dashboard that there’s an electrical and engine malfunction so I pullover and pop the hood. A bunch of smoke comes out and i see a little fire so me and my friends run and call the police. The police and firefighters arrived just as the fire was getting large and it had engulfed the front right side of my car. If the notification that there was a malfunction didn’t come on, I feel as if we could’ve been hurt much worse or even have died. I’m not much of a person that knows about cars and it sounded like my bumper was scraping and by the amount of times i’ve scraped my...

Automatic emergency braking suddenly engaged while driving on the highway. The car decelerated abruptly to a complete stop, causing the driver behind to rear-end me. There were no vehicles or obstacles in front of the car when the brakes engaged - the closest car was at least 100 feet in front of me. This collision was clearly the result of a faulty automatic emergency braking system. I do not feel safe driving the car knowing this malfunction could happen again, especially at highway speeds. Sudden unexplained braking presents a huge safety hazard to all drivers, increasing the likelihood for collisions and injuries. There were no warnings or symptoms prior to the unexpected brake system activation. After the brakes activated mistakenly, warning beeps and “BRAKE!” message appeared. Car has collision damage and has not yet been inspected by dealer. Police report filed.
