2015 Mazda MAZDA3

Infotainment and phone connect system for hands free phone use is not operational. The computer for the system is in a continuous reboot loop. This puts safety or safety of others at risk as I cannot use hands free. Mazda corporate suggested that a software update of the Connectivity Master Unit (CMU) might solve the problem. I brought the car in to Smithhaven Mazda on 090722 for update. The repair technician could not update the computer software and advised customer that the possible CMU problem is cause of concern. I was then advised that resolution would be replacement of CMU at $700. Problem was first observed 082022.

In February, 2022, my 2015 Mazda 3 experienced a major failure, while I was driving on a local road, going 35 miles per hour. All of a sudden, the engine lost power, three warning lights came on, and the car was struggling to go 20 miles per hour. Being near a friend's house, I drove there. From there, her husband followed me home. The next day, my car was towed to the Mazda dealership. The mechanic diagnosed the problem as “found TBS NUMBER: 01-014/16 and inspected coils found they were bad according to lot numbers”. He replaced all four engine coils and all four spark plugs. The service manager told me that the parts were not under warranty. My research revealed that engine coils are supposed to last the lifetime of the car, which is 150,000 to 200,000 miles for a Mazda 3. My car only had 43,048 miles. The spark plugs should have lasted about five more years. I looked into the Bulletin issued by Mazda USA. Mazda USA was first aware of a problem January, 2016. On 17 March 2016, I bought the car. Mazda USA updated the Bulletin to include my car on 29 July 2016. The car was under full warranty at this time and could have been fixed, if I had been notified of the defects. The faulty coils can cause a catastrophic failure, resulting in serious accidents and injuries. My car was a “ticking bomb”, waiting to go off. I was on a local road, with light traffic, not a secondary road or highway, with heavy traffic. Rather than notify customers of the danger of the engine malfunctioning, Mazda USA chose to remain silent. The Bulletin directs that nothing be done until a customer complains. The customer does not know to complain until the car malfunctions! The customer must complain within the normal warranty period. Mazda is hoping that the bad coils fail after the warranty period.

The multifunction / infotainment display in my Mazda went haywire last weekend--it loops through bootup sequence over and over but never loads. Backup camera still works, sort of, but the image jumps and it goes blank sometimes. I can't unplug the display or pull the fuse, or would lose backup camera altogether. So I have no Nav system, can't change radio station, etc.--and am stuck with the 7" screen flashing in my face as I drive. Local Mazda dealer advises that this is caused by cell phone transition to 5G. They took my contact info but did not offer any solution. There have been a couple of local news stories this week about other Mazda owners experiencing this issue. Interestingly, those all seem to report that owners' radios are stuck on a local NPR station. Mine is also stuck on one station, but not the NPR affiliate. https://www.geekwire.com/2022/youre-listening-to-kuow-like-it-or-not-mysterious-glitch-has-mazda-drivers-stuck-on-public-radio/

My 2015 mazda3 was in a collision on 09/08/2021 and my vehicle was totaled. None of my airbags deployed . Fortunately i only sustained neck and back injuries. I believe that i would have avoided these injuries if my airbags deployed properly. Has anyone else reported a problem with airbags on the 2015 mazda3? If there is a problem with the airbag then other owners need to be notified of this safety issue.

MY CARS INFOTAINMENT SYSTEM, WHICH INCLUDES THE REARVIEW CAMERA, STARTED MALFUNCTIONING IN EARLY 2019. THE INFOTAINMENT SCREEN (FOR THE CLOCK, RADIO, GPS AND REARVIEW CAMERA) WAS IN A REBOOT LOOP (CONSTANTLY REBOOTING OVER AND OVER). WHEN THE CAR IS PUT IN REVERSE, THE REARVIEW CAMERA WORKS SPORADICALLY, INCLUDING SHUTTING OFF IN THE MIDDLE OF REVERSING THE CAR. I TOOK THE CARE TO THE ORIGINAL DEALER AND (PER THE SERVICE INVOICE ATTACHED), THEY DIAGNOSED THE PROBLEM AS "CMU FAILURE" WHICH WOULD COST ME $1000 (ONE THOUSAND DOLLARS) TO FIX. I REFUSED, AS I DID NOT THINK IT WAS APPROPRIATE FOR THE CMU TO FAIL ROUGHLY FOUR (4) YEARS AFTER PURCHASE. I GOOGLED THE PROBLEM AND IT'S EVIDENT THAT MANY OTHER MAZDA OWNERS HAVE EXPERIENCED THE SAME PROBLEM.

I WAS DRIVING ABOUT 60MPH ON A 4 LANE US ROUTE WHEN I HEARD A LOUD BANG COMING FROM MY SUNROOF. I LOOK IN THE REARVIEW MIRROR AND SEE A LARGE CHUNK OF GLASS FLYING BEHIND ME. I OPEN THE SUNROOF VISOR PARTIALLY AND NOTICE I AM MISSING GLASS. THE GLASS FOR MY SUNROOF IS TEMPERED. IT WAS ABOUT 65 DEGREES AND VERY HUMID, BUT NO PRECIPITATION. THE PICTURE IS FROM A PARKING LOT ABOUT 10MINS AFTER THE INCIDENT.

GOOD AFTERNOON, MY CAR IS EXPERIENCING THE GHOSTING ISSUE WITH MY INFOTAINMENT SCREEN. THIS IS HAPPENING IN MANY MAZDA 3'S THROUGHOUT THE COUNTRY AND IS A BIG SAFETY HAZARD AS IT IS DISTRACTING WHILE WE ARE DRIVING. CURRENTLY IT IS A WARRANTY ISSUE BUT THIS SHOULD BE A RECALL INSTEAD AND I SHOULDNT HAVE TO PAY TO HAVE THIS FIXED. MY REASONING FOR THIS IS WHEN I AM DRIVING THE SCREEN WILL GO CRAZY AND SELECT WHAT IT WANTS TO AND PLACE CALLS AND GO INTO A BUNCH OF DIFFERENT AREAS. THIS CAUSE ME AND OTHER DRIVERS TO TAKE OUR EYES OF THE ROAD AND ALSO OUR HANDS OFF THE STEERING WHEEL TO CANCEL CALLS OR TO EXIT WHERE THE SCREEN DECIDES TO GO.THIS IN TURN CAN CAUSE ACCIDENTS NOT ONLY FOR MYSELF BUT OTHERS ON THE ROAD AS WELL. THERE IS NO WAY TO DISABLE THE TOUCH FEATURE IN THE SETTINGS ITSELF SO I CANT DISABLE THIS FUNCTION IF I WANTED TO WITHOUT TAKEN APART THE DASH AND VOIDING MY WARRANTY. THIS HAPPENS WHEN STATIONARY, IN MOTION, IN THE CITY AND ON THE HIGHWAY. THIS ISSUE HAPPENS OFF AND ON THROUGH THE WEEK.
