What component or system failed or malfunctioned, and is it available for inspection upon request" - The infotainment system goes into a reboot loop and never starts. At times the backup camera will turn off when backing up. At other times the backup camera will not turn off and will be on while driving forward. How was your safety or the safety of others put at risk? When the backup camera turns off while utilizing it there is the possibility for an incident. Has the problem been reproduced or confirmed by a dealer or independent service center? - Yes, the dealer confirmed the reboot loop. Has the vehicle or component been inspected by the manufacturer, police, insurance representatives or others? - Only the dealer. Were there any warning lamps, messages or other symptoms of the problem prior to the failure, and when did they first appear" - No, they appears a few years ago. I believe the main CPU got corrupted by an HD radio channel.

UNKNOWN cause for short battery life. The battery has been changed 4-5 times since 2020 with a brand new battery. The alternator has been checked and is fine. The dealership is going to check my vehicle again but this is an issue for multiple people with the same vehicle model.

The electronic emergency brake switch freezes in cold weather. The parking brake can not be released until the weather warms. This is safety issue, because the motorists is now stranded. I took my vehicle to the dealership, . but the would not address the problem. This happened 2 times on the following dates 13 February 2019 14 February 2022. I'm retired and very little. I only have about 23000.miles on my vehicle. I live ln New York City and do not feel safe driving in the winter, because my vehicle's electronic emergency brake switch freezes in the cold weather.

smart key. during driving all the lights on the dashboard come on and the siren goes off and unable to have it turn off. After a period of time, its wears down the battery and it is no longer drivable. First time, it was towed to the AAA auto repair and they could not find anything wrong with it. The 2nd and 3rd time, AAA towed it back to Maita Mazda where we purchased it in good faith less than two months ago, and their service department could not find anything wrong with the electrical system. They replaced the battery the seond time, and the issue still occurred again when I turned it off. Then turned it back on as I needed to close the driver side window, and it would not turn on. No one seems to believe me, and we cannot get Maita to take it back and give us another vehicle in its place. It is extemely dangerous to drive in traffic, and we only bought it because it has a big enough trunk for my spouse's walker, and later a wheel chair. It is paid for in full,

Last month, my vehicle suddenly applied the electronic parking brake (EPB) while I was driving. The EPB & related warning lights illuminated & would not release until the vehicle was turned off. After turning off the vehicle, the EPB motor could be heard applying the brake to the rear wheels. When the car was restarted, the EPB would remain off for a period of time but would then suddenly reapply. I took my vehicle to a Mazda dealer & they determined the calipers & EPB motor had failed due to my vehicle not being placed in service mode by the brake servicer. This explanation makes no sense because the brakes were replaced over a year ago (& not since) with thousands of miles being driven since then without this issue arising. I also conducted my own research & found that Mazda has issued at least 3 separate technical service bulletins (TSB) on this issue. The first two recommended replacement of the EPB switch & the third determined that defective calipers were the cause and should be replaced. I asked the dealer to save my calipers & confirmed that they are part of the defective batch noted in this TSB. I have contacted Mazda (including their legal counsel) & they are unwilling to provide any explanation or engage in any sort of investigation. As former legal counsel for an automotive company, I believe this presents a serious safety issue for consumers based upon the fact that a parking brake could randomly engage while driving & cause sudden loss of speed/control. Thankfully, this did not result in harm to my family, myself or others. I am certain that this issue is affecting others based on chatboard discussions I have found online related to this topic (which helped me find the TSB). I am concerned that Mazda may have attempted to undertake a silent recall via this TSB where in warranty customers are covered & out of warranty customers are given the 'service mode' explanation to justify their responsibility. This should have been handled as a recall by Mazda.

Parked by the curb at the Ft. Lauderdale International Airport. I put the car in Park and left the car idling with the air-conditioning running.as it was 95 degrees and about 100 at around 8:00 AM. There was a shuttle van parked by the curb about 11 feet in front of me. I had to exit my car to talk to the driver in the car behind me. I walked to the car behind me and started talking to the driver. I glanced back at my Mazda CX5 and it started rolling forward. I ran up to the car and got the door open and stepped on the brake. The brakes did not engage. I repeated stepping on the brake several times and the car would not stop. I got in the drivers seat to shift the car into reverse and keep my foot on the brake pedal. The car would not shift into reverse. and by this time the Mazda had pinned to the shuttle van a lady who was trying to unload her luggage. On the sixth attempt to shift into reverse the shifter finally moved into reverse and by standers came to the aid of the lady that had been pinned to the shuttle van. Airport security and the Broward County police took the statements. The lady retrieving her baggage declined medical attention. When I checked to see what the police were reporting they did not acknowledge that I was attempting to stop a runaway vehicle. The report said that I failed to put the car in park and left it in drive. It is not possible to get out of a car that is idling and in gear without the car moving forward or backward before you can even get all the way out of the car. This incident happened about mid July in 2017. Near the end of June this year while in my driveway I left the car idling and in park, exited the car walking to the rear of the car and it dropped into reverse. Got back in the car and shut off the engine. July 2017 the local Mazda dealer inspected the vehicle and could not find as problem. Not unlikely with an intermittent electrical anomaly. There were no prior warning lamps in either incident.

The Infotainment system engages in "ghost touch, " where the screen scrolls through and clicks random buttons on its own. This occurs both while I am driving and while I am parked. It will change radio stations, exit out of the navigation, and click other random buttons so that I then have to turn off the display in order to get it to stop. For example, yesterday, it kept clicking the repeat button on the Bluetooth display so I was forced to listen to the same 1 second of a song until I could finally shut the Infotainment off. When this occurs while driving it is a hazardous distraction. Mazda had the same issue with its Infotainment system in the 2016 CX-3 and issued a recall. I reached out to Mazda to explain I am having the same problem but they will not fix it.

When the vehicle is running, but not moving the touch screen display randomly jumps/changes the display. This malfunction has changed the current radio station, navigation map screen, and/or the maintenance warnings/alerts. I believe this "ghost touch" poses a safety hazard not only due to the distracting beeps and screen changes but also the random change/reset of important maintenance alerts such as oil change and tire rotations. My Mazda dealer has updated the software but did not correct the malfunction. They now say I need to pay for a replacement of the touch screen display component to correct the "ghost touch" defect.

This is a follow up to NHTSA complaint ID Number 11442992: After doing a fair amount of research the problem was deemed to be the Front Body Control Module. A new replacement was ordered (about $250). It took about 1-1/2 to 2 weeks for the module to be received and about an hour for its installation. So far the wipers seem to be working correctly although they have yet been 'used', only tested. Googling "mazda wiper problem" you will find others reporting similar problems with the Body Control Module. I found this (https://www.mazda3revolution.com/threads/for-those-suffering-wiper-motor-issues-here-is-the-fix.232623/) forum entry when I did the aforementioned google search. And finally, post replacement I have visually inspected the original module and can easily see one of the components marked "2741" with corrosion around its mounting.

While driving on a remote highway the seat heating was on on both the driver and passenger seat. After a while it felt way ti hot and smelled like something burning and found the passenger jacket (that was taken off and left behind his back to be extensively burnt.

My problem is with the keyless start system. The problem is that if I forget to push the start button to shut down the vehicle and open the door and leave the automobile and shut the door with the key in my possession the auto will keep running until it runs out of fuel. Wouldn't it make more sense for the vehicle to shut down after 3 minutes if the key is not present. As you know people have died from carbon monoxide poisoning by parking in their garage and forgetting to shut down the vehicle and the vehicle keeps running and filling their homes with carbon monoxide. This happened to a older couple in Sarasota Florida with a new car that they just purchased and were not familiar with the starting system. Just wanted to know just how many people have to die before something is done about this problem. I asked my Mazda dealer and they told me that the vehicle will run until out of fuel and basically said that I was stupid for being concerned.

The component that failed was the CMU unit in my screen. I was unable to use Bluetooth and hands free driving which put my safety at risk and when driving at night the screen would light up, reboot, shut down, light up which was very distracting. I took it to the dealership which they said this is happening in cars and they will not cover it. They fixed it at a cost of $864.34. I contacted Mazda and explained how distracting this is to drive and they explained there is nothing they could do but give me a $250 credit.

I would like to express that this is now the second time I have had to take my car in for service and repairs due to the soy-based components they use in the electrical harness that have been continuously eaten thru by squirrels. My car's horn and headlights no longer work again and this is now the second time. I ask that these elements are recalled immediately for safety reasons. Wire harnesses are a critical component to vehicle safety. Wires that can degrade during the normal service life of a vehicle can be deadly. Think about a wire harness with insulation that's been eaten that controls the ABS, fuel injection or an airflow sensor, and you hit a bump in the road and it shorts. Now you lose power or braking. Are we willing to have someone's vehicle fail and the people seriously hurt or dead because of a fundamental design flaw? I can email pictures from my phone to provide evidence of the damage. Again these wires should never be soy based. I don't feel like dying anytime soon because a rodent chewed through a critical component.
