2020 Mazda Mazda3 owner complaints

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.

•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 aw

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 happen

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 fro

The Mazda Radar Cruise Control (MRCC) system performs poorly (it does not hold a set speed well up and down hill; compared to our 2006 Mazda3), but the safety concern is the forceful, sudden, and not-always-predictable braking the vehicle does even if there is not another vehicle in front of us. It brakes, sometimes, for a vehicle in the right lane (we, in the left), and continues to brake unless we override the system. No problem--except if there may be someone following too closely, it could cause a collision. It seems to be related to the MRCC, as no "Brake!" warning accompanies the unwanted brake application. I've contacted Mazda numerous times; they recommended taking it to the dealer. I have--they can find nothing wrong. All of this seems related to a MRCC update (SSP C5) that was do

Fuel pump, car dying out, can't turn off brake release from when it dies. Shaking when accelerating. Fuel gas issue.

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.

in May 2023 the visors of the vehicle hinge melted causing the visors to hang down to eye level and would not hold up causing visibly issues for driver and passenger. dealer said it is a common issue in heat but it blocks forward visibility and won't hold up and if there were and accident, forward movement of passenger or driver can cause the head to hit the visor causing injury.

The front radar sensor failed and doesn’t work anymore rendering the FCW and ACC useless. There is a TSB out about water damage getting into the sensor. There are 2 warning lights on. They first appeared when I turned on my car one day.

I was driving down 2nd Avenue in Manhattan, traffic was crowded but flowing with an estimated speed of 20mph between lights. I believe the distance between my front bumper and the car ahead was only slightly under 2 car lengths in motion. Coming to a stop light, the car in front of me slowed and I followed, applying pressure to the brake gradually. Roughly 2-3 seconds into my braking, the forward collision warning activated (fast beep) followed by a hard brake causing myself and one passenger to lurch forward. The car behind me managed to hard brake before hitting me by a very small margin. As my car came to a near stop the space in front opened to several car lengths, that is a continuous application of gradual braking would have been totally sufficient to stop. Weather conditions were g

My new 2020 Mazda 3 premium with 1,177 miles suddenly took complete control of steering my car. Driving 65-70 MPH on a 3 lane straight highway on a clear day, with light traffic, I moved one lane to my left, and the car took over the steering, pulling my car out of the left lane nearly missing the center cement divider, then darting back across my lane and halfway into the lane to my right,then dashing back to the cement median. I am unaware of how many times the back and forth occurred, I tried to slow the car down to no avail. The car was moving fast, and the pattern the car moved in was very precise, as if the car knew not to hit the median and go further into the lane to my right. Finally the car stopped steering itself, and I was able to exit the highway. My car was not damaged. I

Lane departure warning activated and attempted to correct during a gentle curve. The location had shifted lanes due to construction, so clear lines were visible but not the actual lane to follow which is a frequent occurrence in New York City. The system came close to steering me into the adjacent lane occupied by another vehicle forcing me to fight the correction. There was a lane departure warning on the dash and I believe the blind spot indicator was on (i.e. the adjacent vehicle was detected in some capacity). I considered this especially dangerous as in this zone also had very tight lanes so my physical correction could have also caused an accident. There was no malfunction of the physical components. No dealer or service center has reproduced the issue however I have discussed with o

Automatic switching between high and low beams is unavailable.

The contact owns a 2020 Mazda Mazda3. The contact stated while driving 35 MPH, the ABS warning light illuminated, and the brakes locked up and caused the vehicle to stall. The contact was able to restart the vehicle however, the failure persisted. The contact had taken the vehicle to a local dealer to be diagnosed however, the dealer was not able to duplicate the failure. The vehicle was not repaired. The manufacturer was made aware of the failure. The failure mileage was approximately 2,000.

My car's automatic emergency brake is deploying without warning, during driving, when there are no other cars in my forward proximity. I took it to the dealership to have it fixed, and on the drive home, it did it again. There is a recall for similar makes and models for this year, but my car has not been included.

I pulled into the driveway (at about 5 mph) of my passenger's home, when a very loud, metallic pop occurred somewhere inside my vehicle. I could not discern the problem by visually inspecting the car. Upon returning to my home, I arranged for the dealership to inspect the car's suspension. They found that both rear springs had snapped off from their lower vehicle attachment points. At the time of the incident, my car was less than 6 years old and had approximately 62500 total miles. I had the dealership replace both rear springs and associated attachment hardware. Prior to this failure, the dealership had routinely inspected the suspension of my vehicle as part of PA annual inspections. I experienced NO warning symptoms prior to the suspension failure.
