This car's backup camera has been un-usable ~50% of the time, dating back to last year, due to the issue described in the recall. Westcott Mazda refused to inspect and certify the existence of the issue and simply said parts to fix it were unavailable. This recall was issued over 9 months ago.

Vehicle touch screen has aggressive and persistent -??ghost touch-?? during vehicle operation (while in drive), which should not be possible while in drive at all. This causes any setting or feature accessible through the vehicle -??infotainment-?? system to be activated at random leading to distracting, undesired operation. There is no setting within the -??infotainment-?? system that allows you to disable the touch screen, leading to dangerously distracting situations. There is a voluntary extended warranty period provided by Mazda, but I was not notified required by law, nor was the warranty service offered to me when bringing my car to dealership(s) during the warranty period. Mazda is not willing to pay to fix the acknowledged safety defect.

The "infotainment" system, which includes media, navigation, hands-free calling, and the backup camera function, frequently malfunctions. The system will either freeze, or it will execute button presses on its own. The result is that it will change audio selection, make hands free calls via the connected phone, etc. on its own with no driver interaction, which is distracting while driving and could and has caused hazardous driving conditions. While I am listing the most recent occurrence in this form, this has been occurring on nearly every drive for the last 2 years. This typically happens in stop-and-go traffic. The vehicle has a manual transmission and the movement in the center console caused by shifting may be causing loose electrical connections to be disturbed and contribute to the behavior.

1. it is available for inspection 2. the infotainment system cuts off an on at will and switches views when using the navigation system which can cause you to be distracted when driving, especially if you're driving in an unknown area. 3. vehicle has been seen by the Mazda dealership which refuses to repair even though this is a known problem with this model as well as other models. 4. no warnings, just started changing screens all the sudden. Mazda is well aware of this problem and the driving dangers that this poses but yet refuses to address the issue. I did discover that they did issue some type of notice on this but it was never a formal written recall. Only fixed if you took in and told them about the problem, most people I would think did not do this because it is cost prohibitive, that system cost about $1400 to replace. Thats not pocket change for most people.so without a formal written mailed letter most people just tried to live with it.

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 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.

Infotainment system keeps rebooting in an infinite loop. Vehicle was parked when issue started. Vehicle had been off for about 3minutes prior to issue. Infotainment was working prior to being off for 3 min.

- Glendale, WI, USA

Infotainment system restarts 3 to 5 times, when first starting car, when temperatures in unheated garage are below 50 degrees. I drive four to eight miles, with heater on, before it stops restarting. Have taken to dealer 3 times, while under warranty. All they do is reboot it. Now the car is no longer under warranty and I refuse to take it back, and be changed for something that should have been fixed the first time. This just might be a deal breaker in buying a Mazda as my next car. Very annoying.

Takata recall the infotainment system is going haywire, making ghosts selections such as calling ppl, self selecting settings and all other buttons at random times during driving which has become extremely distracting and dangerous to drive the car with this issue. This is apparently a known issue to Mazda but they refuse to fix it. All they will offer is swapping it for another infotainment system that will eventually do the same thing again at the customers expense. This takes place while the car is traveling at 5mph or less so it most frequently happens when I am slowing to take turns or traveling in my neighborhood and while at a stop at random times. I have no control over the system once it starts glitching and making calls and changing settings or dialing numbers, I cant hang up im forced to disconnect the bluetooth from the phone but that only prevents it from making calls it still continues to go to the setting at press random buttons

2015 Mazda 3. consumer writes in regards to no recalls being issued for defective parts on vehicle. The consumer stated he was not notified of any recalls for this vehicle. Updated 09/29/2017

Hot weather acceleration and blind spot monitoring system (bsm) issue: In extremely hot weather bsm off light turns on repeatedly while the vehicle is in motion or starting from complete stop. At the same time the infotainment system display flickers in sync with the bsm off light appearance. When this occurs there is a clicking sound coming from the front of the car/where the engine is located. The sound is accompanied by temporary loss of acceleration when in motion or starting to move from a complete stop. When this occurs while starting from a complete stop, the engine revolutions (rev) drops below 1K RPM despite gas pedal input thus the car would not move/accelerate for about 5 seconds. When it occurs when the car is in motion such as on the highway or merging onramp into the highway the car unsafely slows down despite gas pedal input. Again this issue is observed during unusually hot days eg. July 22, 2017 in St. Louis, Missouri.

The day was hot and I was in stop and go traffic with the ac set to 72 degrees in my 2015 Mazda 3 with just 21K miles on it. My car unexpectedly stalled and the check engine and charging system/battery lights came on briefly in the dash. I had to shift into park and push the button to restart my vehicle. The car's ECU/PCM did not set any codes and the problem has not occurred again since that hot day. This is a danger because the sudden loss of power could result in a rear end collision luckily I was in stop and go traffic. Dealer and Mazda have been slow to investigate this thoroughly. Feels like they just want to send me on my way without doing a thorough investigation of this issue.
