2021 MAZDA MAZDA3 Complaints

Vehicle detects cars in other lane as an impeding collision in turns, activates emergency braking when no collision is imminent.

At around 3600 Miles my Mazda which I had for only a couple of months displayed a low engine oil light which required a visit to the dealership.This was under normal driving conditions.

My Mazda 3 2.5T has been burning oil in excess. The car has a total of 24,000 miles and has been serviced 3 times. I have had to add oil in between every service. The oil has been completely burned off by 4,000-5,000 miles. I have noticed that other people have been posting about the same issues online. When talking to the dealership they state that they have noticed this issue with the 2.5T’s but offer no fix and seem to overfill the engine oil to try and compensate.

Excess oil consumption in engine. Low light came on around 5,000 miles and dipstick showed engine oil was at the minimum mark.

Engine is consuming excessive oil. Dealership states there is a TSB out but the fix is to keep topping the oil off. I would like an investigation to determine the root cause of the oil consumption on a new engine.

The vehicle was badly rear ended and the airbags didn't deploy. The dashboard indicated an "airbag malfunction" after the collision happened. The failure of the airbags put myself and my passengers at serious risk; if we weren't wearing our seatbelts, which we were, we would have been gravely injured. The vehicle is less than a year old and still under warranty.

Low engine oil warning between oil changes. Burned 3+ quarts between 5000 mile and 10,000 mile service.

A have a new 2021 Mazda 3 Hatchback with 3,500 miles. As I was driving and approaching a traffic light to stop, my car shut down completely while in traffic. I turned on my hazard lights, put the car in the park position, and restarted the vehicle. As I proceed with driving, when I made a right turn onto the blvd, a minute after turning when I came to another stop, the vehicle shut down again. I called Romano Mazda in Syracuse, NY. They set me up with an appointment for the following week and gave me a rental. They kept my vehicle for 3 days. Per the technician, there were no codes found or pending codes. said they contacted the Mazda tech line and was told there was no history of the fault within the ODR date and released my vehicle back to me. My vehicle only has 3,500 miles on it. ITs a huge safety hazard. I transport my mother who is 93 years of age. I don't feel confident driving it. especially on the highways. In 2019 over 262,000 Mazdas, including the Mazda 3 hatchback were recalled for problems with vehicles stalling out. Sound like the same issue with the 2021's

My car started to show a warning on the dashboard that the airbag system is malfunctioning. The alarm would come on for a few seconds, then turn off, then repeat like that multiple times every drive. At the time it started, my car had less than 500 miles on it, and it continued after that until I got it fixed. I took it to the Mazda dealership where I bought it, and they said it was a short circuit to the driver's side airbags. They told me that could have caused the airbags to deploy prematurely or not at all in an accident. I am also a part of a Mazda 3 community and am active on the forums, and in the last month I have seen at least 30-40 other 2021 Mazda 3 owners also report the same exact error code, with the same short circuit issue being cited as the problem by the dealership. Parts are on backorder for weeks for most of these owners, and some of them were told by the dealership to keep their car while they waited for the part, whereas my own dealership told me it was unsafe to drive the car and to have it towed to the dealership instead.

Context: ADAS was not on. Lane keep assist is disabled in system settings entirely as it is dangerous. Blinkers were on, I was pulling out from parallel parking into left turn lane onto a straight road with slight incline. Car is of the Turbo trim on stock tires. Upon finishing pulling out of parallel parking spot and gassing the car, torque vectoring or some underlying collision avoidance may have phantom activated. I felt torque shift to the wrong tires, unsettling the car, and the wheel -- with no human input -- jerked to the left to force me into the lane left of intended. I applied throttle and steered right back into the correct lane, but the car was applying torque to the wrong tires and applying a left bias to the steering. Only after I got above 25mph and held straight did the car settle. Almost caused an accident if the lane was not empty due to car unsettling itself into the left lane.
