2016 MAZDA MAZDA3 Complaints

Apparently all of sudden the front occupants seat belt had lock and malfunctioning to the point you are unable to pull the belt strap to securely wrapped around the passenger, took it to have it evaluated at the request of the auto maker, supposedly this what I understood from two separate auto repair shops ( Mazda) dealership and a reliable auto repair (Apex) shop stating that a spring loaded system mechanism part was actually missing and that the standard mechanical labor (code) cost for the repair were not (unknown) listed while the other suggested the whole seat belt needed to be replaced I strongly feel this should be a safety related issue for both the driver and passenger seat belts should be recalled and carefully looked into for driver/passenger safety reasons.

There is a main board failure that controls the information screen and back up camera The part number is TC3M-66-9C0B . The screen will keep rebooting not allowing the back up camera to work. According to Mazda dealer personal Mazda will not cover this. This is know to be a regular problem with many of these cars

I have had to replace the battery on this vehicle three times in the last year. I have taken it to Mazda who replaces the battery. No excessive electrical power is being used with in the car. The car is driven regularly as well.

Parking brake does not fully disengage. This causes the rear brakes to wear prematurely and also has the potential to generate excessive heat.

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.

Timing cover leak, all maintenance was completed before the service bulletin. This is a TSB but should be a recall for how common this issue is as they stated it could be caused from the assembly line during a pressurized test. “ This may be caused by oil escaping from a fine clearance created at the sealant applied to joint (A)between the cylinder block (B) and head (C) when the engine was pressurized during leak testing on the engine assembly line.” TSB Bulletin No.: 01-018/18. Timing cover issues are not something that should be happening under 100k miles.

Front end passages side shaking with 60 mhg. And some time smelling gasoline when first started up my car.

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. I have seen a safety recall on other Mazda's with relation to the infotainment screen, but I do not see one here. I wonder why? To repair this crucial component would cost many hundreds of dollars -- something I am not in a position to do. Mazda claims this infotainment center is not under warranty, but with so much important information and safety features embedded into it, I think it should be corrected by recall. Thank you for investigating this issue. Regina

The windshield wipers work but the washer does not squirt the windshield washing fluid out and it the reservoir is full of fluid but there are certain days in which I need that to work because my visibility is greatly reduced which has made the risk of accident that much greater. it says there is a recall pertaining to this problem and the fix was a relay However nothing comes up for my specific car when I enter the Vin but I would like this problem fixed and I’m not sure how to go about it

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.
