Mileage when the problem started
Owner reports
Selected complaints filed with NHTSA by 2016 Mazda Mazda3 owners, lightly cleaned up (personal details are redacted by NHTSA).
The contact owns a 2016 Mazda Mazda3. The contact stated that while driving and while starting the vehicle, the instrument cluster was inoperable. The contact also stated that the instrument cluster screen was peeling, and critical information for the vehicle was not displayed. Additionally, the infotainment system became intermittently inoperable due to the failure. The dealer was contacted; however, the vehicle was not diagnosed or repaired. The manufacturer was not made aware of the failure. The contact expressed concerns that the inoperable instrument cluster created a hazardous and unsafe condition due to the complete loss of instrument panel functionality. The approximate failure mileage was 142,000.
Car began to smoke. Roof caught fire at driver's visor while occupied with 2 people. Both able to exit safely. Neighbor put out with fire extinguisher. Inspected by insurance adjuster - total loss. Dealership notified. No warning lamps or messages.
The infotainment system fails to work - it is where I can access information re: maintenance schedule, or any info that is associated with a lit engine light. In addition the charging system for my mobile phone has ceased working. This includes both the usb ports and the lighter port which can be adapted with a charger that works in that receptable. These are all safety issues as far as I am concerned. Not having information related to the vehicle engine light is a big issue, but so is the fact that I can't charge my phone on long distance drives. If I needed assistance, I would be unable to contact anyone without a working cell phone. Because the display also controls the ability to pair a phone with blue tooth, there is concern for other drivers of the Mazda 3 (mine is a 2016) will be using the phone regardless of the bluetooth malfunction. …
NHTSA Recall # 23V-487 Manufacturer Recall # 6023G issued July 14, 2023 After repeated phone calls to the Manufacturer and the Mazda Dealership, the recall has not been fixed. I have been told that the parts are not available. As of this date, 16 months after the recall, Mazda has not fixed the problem. I have been told by the Manufacturer and the Mazda Dealership, that parts are not available. The manufacturer told me that they have no date when parts will be available. I have asked to speak with a Manager at the Manufacturer and was told that there is no one else to talk to except Customer Service. I asked for a contact at the Corporate level that I could send an email to, and was told that there was no email address available. They have suggested that I get it fixed at my own cost and submit a claim that may or may not be reimbursed. …
The rear parking assist camera has only worked intermittently since I purchased the car. There is really no pattern to when or why the camera chooses to work or not work, but It seems most affected by opening and closing the rear hatch: if it's working and i open the hatch, it stops working; if it's not working, opening/closing it will often cause it to work again. This is a problem because parking/backing up becomes a challenge when it's not working. This puts my safety at risk because it increases the chances of me having a fender bender when in reverse.
The Mazda Connect touch screen in the center display does not accept touch commands properly or will often operate by itself (ghost touch). When it does this, even though I will have navigation on, it will interrupt the service to jump screens, causing me to lose guidance and force me to pull-over to try to deal with the issue. I have had to swerve in my lane trying to correct the issue until I have the opportunity to pull-over, and it has been dangerous to me and the folks on the road with me when this happens.
In mid-2021, the Mazda Connect infotainment system suddenly stopped working. Upon starting the car, the software boots over and over again. The Bluetooth is inoperable; radio plays but I cannot change stations; steering wheel functionality of these features is absent; backup camera is intermittent and dimmer. The latter is a safety issue. The Mazda dealer diagnosed a malfunction of the connectivity master unit (CMU) and said they have had a rash of the same problem with 2016's recently.
Infotainment system / center console doesn't work properly. Buttons would be pushed at random, changing stations and flipping thru menus. It deteriorated to the point where it would constantly reset itself, flashing a very bright (and not dimmable) Mazda logo over and over. Mazda insisted on charging for repairs so I have instead simply removed the center console instead. otherwise the bright flashing light at night was distracting to the point of dangerous.
When I checked for recall information 2 recalls were listed under my car's vin #: Recall #1: 3219D with Closed status. Recall #2: 6023G is listed as Active. But, when I tried to schedule a repair for the active recall, the manufacturing website ONLY listed the "closed" recall (3219D) was listed as available for repair, which is bizarre. Please see the attached screenshot of the website. Thanks.
The Mazda Connect infotainment system will begin to press random buttons and continue to perform its own actions, at one point resulting in it dimming my screen so low I could not see my backup camera screen, which is a huge safety hazard.
