To Whom It May Concern: On Sunday October 2, 2022, while driving in very rainy conditions caused by Hurricane Ian, my windshield wipers failed. On Monday, October 3, 2022, I took the car to an independent mechanic at Chesapeake Import Services in Annapolis, MD. The auto mechanic ran a diagnostic test on my vehicle to discover an electric malfunction caused by a defective relay. This is the same issue that is noted as part of the recall that has already been identified here: https://static.nhtsa.gov/odi/rcl/2019/RMISC-19V272-0572.pdf. Unfortunately, my VIN does not fall into the recalled VINs. I am requested that you review and expand the recall to include additionally impacted vehicles, and this issue seems to be significantly more widespread that originally noted. …

I took my vehicle into RBMC dealership due to the vehicle was experiencing electrical issues and had an open recall / still does. The dealership said I can't have a dash cam plugged in to a charging port. FCM / LDW / E-Break staying on / throwing error codes = C1001 FSC failure type 97 & U3003 EPB control module power supply failure type 16. They gave me back the car the battery failed the next day and when I called them they banned the VIN of this car to ever return to them. ( the battery was under factory warranty) the issue has only gotten worse and removed my dash cam as they demanded and now I can't get the car fixed and the issue has gotten worse then taking the car to this dealership less then 30 days ago. They also did not perform the recall when the car was there. …

In 2023, the reverse camera would either flicker or completely shut off (displaying a blank screen) while the reverse gear is engaged. While reversing the vehicle to park onto the property the rear camera image failed to display in the vehicle, leading to a collision with the curb. The limited visibility out of the rear windshield for the Mazda 3 leads to a typical driver relying on the camera display to show obstructions not visible through the rear and side mirrors. This failure lead to the car impacting the curb and the passenger being shocked that the car was in an accident. If that was child or small animal, they would have been hit or run over. Luckily, this failure only resulted in property damage, a large dent in the bumper, and possible exhaust damage (see attached). …

I was driving in the rain on the freeway and my wiper stopped working on 12/27/2022. Dealership diagnosed the issue that it was caused by the front body control module with an internal relay failure. The cause was exactly the same as the recall campaign #3219D after my research. However, the original recall did not cover my vehicle even though my vehicle's model year is exactly the same as stated in the recall campaign. I had to pay out of pocket to repair this issue at the dealership ($663.34) and went back and forth with Mazda's customer service and they could not do anything because my VIN does not match the original recall. The vehicle was repaired on January 2023 but I was not aware that I could file a complaint here on NHTSA. …

This is related to the existing recall with the backup camera. I have intermittently experience, fuzzing of the review camera. I have also experienced total loss of the review camera. In addition, I have had occasionally experienced the panel system not switching over to the rear view camera. The issues appear to be associated with opening and closing the rear hatch and if occurred could sometimes be resolved by turning the car off and back on. The issue was persistent and occurring on a more or less regular basis, but then in the last month it has ceased to occur though I have been opening and closing the hatch on a regular basis... …

Mazda has a warranty extension for the 2014-2016 Mazda 3 infotainment touch screen as it may malfunction and glitch. This glitch can be a distraction as the system believes that it is being touched and may cause many things to change in the car such as radio station, navigation setting, and even some vehicle setting accessible from the infotainment screen, causing distractions. However, this issue is also possible on newer 2017 and 2018 models, and there is currently no program to fix the issue. While Mazda may seem like this is not a safety as the touch screen is disabled above 5 MPH, it can still cause distractions when coming to a stop and while stopped which may result in an accident. I think this needs to be resolved and Mazda needs to acknowledge that this touch issue "Ghost Touch" can affect all Mazdas with Mazda Connect 1. …

The touchscreen has started to exhibit similar issues as seen in previous recalls for the Mazdas. Commonly known as "ghost touch," the screen receives erroneous inputs, causing settings to change or unwanted functionality to start/stop. Depending on the active screen, the system will exhibit different behavior. In my case, the discoloration is directly at the 6 o'clock position. Whatever application button is there is the one that will be triggered. On a Bluetooth connection, that is the random button. On the AM or FM application, that is the seek button. On the settings menu, that could be any number of important things, including safety systems' settings including the ability to disable traction control. You can see on the display where it has been overheated and is discolored. This is the same location that the "ghost touches" occur. …

Mazda had previously issued a Special Service Plan (SSP) to remediate issues with their Mazda Connect Center Display (infotainment system), specifically "ghost touches" and "spider cracking" of the screen: [redacted] This Special Service Plan only applied to 2014-2016 models of the Mazda3. I own a 2018 Mazda3 which has the exact same issue described in the above service plan. Searching online, I am far from the only person who is affected by this issue that continues to be present in newer models of the Mazda3. Mazda should replace my (and others) infotainment system, as it is unusable and distracting in it's current condition.

Safety Recall 6023G - NHTSA Campaign Number 23V-487. The car was purchased in 2018. On 5/29/2024 the backup camera view has gone black, providing no image. Since I've owned this car, the backup camera view appears, sometimes flickers, and now, has gone completely black, only to "pop" on randomly. I have asked the local Mazda dealer on multiple occasions, since purchasing the car, if it can be repaired/replaced, but am told parts are not available or that there is no "start date" on file. The mechanic has done something to that camera system when the car gets an oil change, and the problem goes away, only to return.
