Forward Collision Avoidance owner reports: Mazda Mazda3 years in the records

The records describe a problem worth checking before purchase.

“While driving on a residential street the automatic emergency braking system activated and brought the car to a very abrupt stop but there was nothing in the front of the car to activate the system. There were no cars in the on-coming lane and no cars in the lane beside my car. When the car stopped the Brake warning appeared in the windshield and a warning tone sounded. It was in the early evening and it was raining. Fortunately there were no cars behind me so there were no injuries. I took the car to the Mazda dealership and upon inspection they noted that the radar system associated with the automatic emergency braking system was malfunctioning and not correctly calculating the distance between the car and other objects. They are in the process of replacing the radar. If this had happened on the highway at higher speeds or if there had been a car behind me I would have been injured.”

“on 3 occasions may 2023, June 2023 and July 2023 the forward Collison camera activated. in May and June it showed the vehicle to near stop like radar cruise control in rush hour speed traffic. in July 2023 it sounded the alarm and came to a full stop in heavy traffic. it occurs on bright hot days going straight no turns no oncoming traffic no traffic around and no obstacles hold or dips. this can cause the car to stop immediately and cause an accident. App detects problem with system but dealer cannot find problem and blame camera or GPS or satellite radio factory equipped.”

“•The first incident I had with the SBS was about a month on the highway, I was approaching a vehicle that was braking due to upcoming traffic. I had plenty of time to stop, upwards of 8-10 car lengths. Yet my SBS kicked in and slammed the brakes, jarring me forward. Luckily no one was directly behind me at that time because I have no doubt it would have caused an accident. At that time, it was the only time it had occurred, so I wrote it off as the sensor being a bit too sensitive. •The second incident I have had was recent, 11/23. I was pulling into a parking spot at work, that has a concrete wall to section off parking spots. I was low speed, turned into the spot and the SBS activated, slamming the brakes, resulting in me being propelled into my steering wheel. I was roughly 5-6 feet away from the wall”

“I was traveling approximately 5 mph with approximately 15 feet from the car in front of me, maintaining a constant following distance. The collision warning sounded, followed by emergency braking within 1 second. No collision was imminent.”

“I was traveling 25mph with no obstruction in front of me, when the collision warning sounded. The braking system did not activate. No collision was imminent.”

“Was letting car slow down for red light. No cars in front of me. Suddenly the car braked and the brake warning came on. I was pretty far back from the light. I took the car to the dealer and he said the occurrence did not show on the computer. There was a recall for this problem but not for my car. If someone had been behind me or if this happens on a busy street, I would be rear ended. There have been other computer problems with this car but they never happen when the dealer checks for them.”

“While driving the vehicle decided to suddenly brake ....... thinking it was dangerous ..... lucky no one was behind me ..... that was really scarry and could have caused an accident for no reason.”

“I was on the Queensboro Bridge headed from Queens, NY into Manhattan on the afternoon of August 29. Weather was partly cloudy and dry conditions. Traffic was bumper to bumper and moving anywhere from 0mph to maybe 5mph. I was in the middle of the bridge driving approximately 5mph and my 2020 Mazda 3 beeped (collision warning) and applied brakes. I was almost rear ended and my two passengers were jolted forward. I maintained a safe following distance the entire time. I believe a van on my left triggered my car’s actions as it passed. I was in no danger of getting into an accident although I was quite shaken up since this is the first time my car applied its brakes. I have an appointment to bring my car in and would like the automatic braking system disabled. Previously, the car from time to time has alerted of a collision always under 40mph and a previous inspection of my vehicle (after I reported collision warning activation) revealed everything was working properly.”
