2021 Mazda MAZDA3

The driver window, upon attempted to be let up, will start to go up then go all the way down, ignoring the function to go up. This is a safety concern, as harsh temperatures and foreign objects are able to enter the vehicle cabin at any time, including driving. The problem has been reproduced by a dealer, and the vehicle is available for inspection upon request. There are no warning indicators for this issue beyond witness the failure occur in real time.

My 2021 Mazda 3 was bought used in August 2023 and is about a year old in my possession. it has been at the Mazda dealership for repairs multiple times since August 2023. it dangerously stalls and hesitates when trying to accelerate from a stop position. When the brake pedal is released and I start to accelerate like merging onto highways,the car rumbles or shakes slightly and then shuts off. I Came across a review online that had the exact same problem and it stated a PCM update solved the issue. I have been to the dealer frequently since purchased and they kept my car for over a week and claimed they could not reproduce the customers complaint and there is no diagnostic code generated. There is Frequent parking light malfunction alerts, switch operation not accepted alerts, Brake alerts on desolate roadways I believe this vehicle behavior is dangerous on multiple levels, but the dealer Refused to remedy the complaint or give me copies of the papers that I signed, stating they are only for the dealership. I also received a notice in the mail for a class action settlement for faulty fuel pump used in MAZDA vehicles but not the 2021 Mazda 3 although it displays the same Dangerous behavior. So between the faulty fuel pump or required PCM update the vehicle is questionable to drive safely under certain circumstances. The dealer inferred I should have purchased a used certified Mazda from them instead. Thanks

While driving at a normal speed on a clear, sunny day with no other vehicles close by, I heard a loud crash sound and my car's sunroof unexpectedly shattered. The inside glass panel looks like it's shattered and it caused tiny glass shards to fall inside the vehicle onto my right arm and the surrounding area. I closed the cover to prevent more from falling. This occurred without any prior warning, signs, or symptoms such as unusual noises or warning lights from the car. This incident posed a significant safety risk, not only due to the distraction, shock of the sudden noise, glass falling, injury in a potential accident, but also the potential for physical harm from the glass shards. Thankfully, no injuries occurred, but the potential for serious harm was evident. This problem has not yet been inspected by the dealer or confirmed by an independent service center, and there has been no opportunity for an inspection by any manufacturer, police, or insurance representatives. However, I've reached out to Mazda, both locally and corporate and am receiving a run-around, no surprise. I will attach photos of the inside and the outside of the glass. The outside photo was taken after the cover was closed. However, the broken sunroof is available for inspection upon request.

For the past 7 months (since July 2023) the passenger rear tire keeps loosing air pressure about every two weeks requiring more air. It always drops to 10 points below the other tires. The tires have been rotated twice so it is not a problem with the tire. I believe there is a recall for the same or similar issue on Mazda 3s just not including my VIN#. I brought my car to good year a few times unable to stop this from happening.

Experiencing a known excessive oil consumption issue. Low engine oil warning light came on and upon checking, oil was low. This occured at 4000 to 4200 miles. It occured again about 4000 miles later and again at a similar interval. I notified the dealer and scheduled a repair date but I am concerned of other possible damage that may have already occured due to this issue. An oxygen sensor needs to be replaced and is most likely due to the engine malfunction. The cause of the consumption is said to be damage to the valve seals on the exhaust side.

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
